There was no significant association between the presence of lateral malleolar bursa and hindfoot valgus severity. Extra-articular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. Although most of these findings are radiographic, their presence at 5 years raise concerns about what will happen at these joints 20 to 30 years in the future. A lamina spreader or a towel clip can facilitate distraction of the articular surfaces, making the debridement easier, but this can damage the bone if it is soft. A valgus deformity is common in posterior tibial tendon dysfunction. When looking across the sinus tarsi, the surgeon can see the middle facet of the subtalar joint. With a fully threaded screw, the maximum number of threads is placed in the neck of the talus, maximizing the compression. Early detection of lateral hindfoot impingement has been demonstrated to improve patient outcome. The guide pin is removed, and the small bone fragments that have been mobilized are packed into the tarsal canal and the sinus tarsi area. I have olecranon impingement injury from last two and a half years, and i am unable to continue my activity, what should i do? For potential or actual medical emergencies, immediately call 911 or your local emergency service. It also facilitates simple fluoroscopy access for a lateral view. The subchondral surfaces are heavily feathered or scaled with a 4- or 6-mm osteotome, which creates a broader, bleeding cancellous surface required for successful fusion. Calcaneal offset index to measure hindfoot alignment in pes planus. The medial healthy bone should be included in the fusion while bone graft is placed lateral between the talus and cuneiforms. If placement is satisfactory, the guide is removed; if not, another attempt is made to place the guide pin correctly (Fig. 20-2K-M). 20-2R). The impinging lateral wall is removed so that it is approximately in line with the lateral aspect of the talus. Much has been written about arthrodesis of the foot and ankle. There is significant interest lately in doing the subtalar fusion arthroscopically. With a fully threaded screw, the maximum number of threads is placed in the neck of the talus, maximizing the compression. In chronic malunion/nonunion situations, the reduction could be difficult. Pol J Radiol. Under these circumstances, a small curet is used to remove the cartilage from the posterior facet. O, When lateral subluxation of the subtalar joint is present, the joint must be reduced and not fused in situ. Extraarticular lateral hindfoot impingement is associated with advanced posterior tibial tendon tears and increased MRI hindfoot valgus angle. The agreement between the two methods was poor. A hindfoot arthrodesis places more stress on the surrounding joints and could accelerate degenerative changes of these joints. An official website of the United States government. Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. The pin placement is confirmed by fluoroscopy. The author prefers two screws, starting off the weight-bearing surface posterior on the calcaneus, one screw aiming a bit medial into the neck of the talus while the second screw goes across the posterior facet more lateral. When making an incision, the surgeon must always be cognizant of the location of the cutaneous nerves about the foot and ankle. If any tension is noticeable on the skin edge, some type of a relaxing skin suture should be used. Posterior tibial tendon dysfunction is the most common cause of acquired flatfoot and hindfoot valgus and may lead to medial and, with advanced disease, lateral ankle pain [1, 2].This lateral ankle pain has been attributed to extraarticular lateral hindfoot impingement including talocalcaneal (between the lateral talus and calcaneus) [3, 4] and subfibular (between the calcaneus and fibula . The cutaneous nerves can be quite superficial and easily transected but sometimes become adherent within scar tissue. Hindfoot driven: Trauma (varus malunion of talus fractures) 2.5 cm (1 inch) block or book is placed under foot such that 1st ray is unsupported. The most common indication for a subtalar arthrodesis is arthrosis secondary to trauma, usually a calcaneal fracture, rheumatoid arthritis, primary arthrosis, or talocalcaneal coalition that cannot be resected. However, extraarticular soft-tissue and osseous impingement is an unrecognized entity that can cause lateral ankle pain. This will align the metatarsal heads and prevent one head from being too prominent, which can result in an intractable plantar keratosis. If the surgeon fails to recognize this malalignment and places a bone block into the lateral side of the subtalar joint, wedging it open will not reposition the calcaneus into correct anatomic alignment (Fig. A hindfoot arthrodesis places more stress on the surrounding joints and could accelerate degenerative changes of these joints. Two screws are routinely used. and transmitted securely. Conservative surgery consists of removal of bone spurs and osteophytes from the midfoot joints. HealthTap uses cookies to enhance your site experience and for analytics and advertising purposes. 10. By overdrilling the calcaneus, intrafragmentary compression at the arthrodesis site is achieved. If a previous calcaneal fracture is present in which the lateral wall needs to be decompressed, the peroneal tendons are elevated from the lateral aspect of the calcaneus as far posteriorly and plantarward as possible. The posture of the forefoot also needs to be considered because if there is more than 10 to 12 degrees of fixed forefoot varus, after a subtalar arthrodesis, the patient cannot compensate for this deformity and walks on the lateral side of the foot, resulting in discomfort beneath the fifth metatarsal head or base, or both, and in severe stress on the lateral ankle ligaments. Rosenberg ZS. Objective To investigate the effectiveness of Tang's arthroscopy approach in treatment of anterior and posterior ankle impingement syndrome. The patient is placed into a removable cast with an elastic bandage to control swelling but is kept nonweight bearing for 6 weeks. Metatarsal angle 1. This requires the patient to walk on the lateral aspect of the foot, causing patient dissatisfaction. what about such results indicate "nerve impingement, " rather than something more serious? The arthrodesis site should be stabilized with rigid internal fixation. To determine the alignment, the surgeon first must evaluate the normal extremity. The site is secure. Placing a patient into a cast without adequate padding is not advisable. To do this, the surgeon must consider the entire lower extremity and not just the foot. Vacuum-assisted closure (wound-VAC) can be extremely useful to manage a wound slough. Note the calcaneus is dislocated with subfibular impingement. 3. Figure 20-1 Deep skin necrosis after a medial incision in a diabetic patient. N, Wound complications are not uncommon with distraction bone blocks. The incision should be straight. A 7.0-mm drill bit is used to overdrill only the calcaneus, creating the glide hole. Case study, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-47551. All patients underwent tomosynthesis, radiography, and computed tomography . To learn more, please visit our. The skin incision begins at the tip of the fibula and is carried distally toward the base of the fourth metatarsal. This can include talocalcaneal, calcaneofibular (subfibular) or combined talocalcaneal-subfibular impingements. The incision is carried directly to bone, and slight stripping is done on each side of the pin to accommodate the washer. One factor is probably related to the overall stiffness or laxity of the surrounding joints. It is not necessary to strip the peroneal tendons off the lateral side of the calcaneus unless a lateral impingement from a previous calcaneal fracture requires decompressing. Interpositional bone graft is used to reestablish the talocalcaneal relationship. A well-aligned subtalar fusion in a patient with a severe genu varum or valgum will be malaligned when the proximal deformity is corrected with a knee replacement. This results in a rigid internal fixation with maximum purchase and interfragmentary compression across the joint. Posterior tibial tendon dysfunction is the most common cause of acquired flatfoot and hindfoot valgus and may lead to medial and, with advanced disease, lateral ankle pain [1, 2].This lateral ankle pain has been attributed to extraarticular lateral hindfoot impingement including talocalcaneal (between the lateral talus and calcaneus) [3, 4] and subfibular (between the calcaneus and fibula . MR images from 75 patients (45 women and 30 men) with MRI evidence of posterior tibial tendon tears were evaluated for grade of posterior tibial tendon tear, hindfoot valgus angle, osseous contact or opposing marrow signal changes at the talus-calcaneus or fibula-calcaneus, peroneal tendon subluxation-dislocation, and presence of lateral malleolar bursa. Talk to a doctor now . Bone graft from the iliac crest is rarely necessary when carrying out a foot or ankle arthrodesis. no calcaneofibular impingement. 50% off with $15/month membership. If 7.0-mm cannulated screws are used, the initial hole is drilled with a 4.5-mm bit, just penetrating the neck of the talus. The rates of nonunion have been reported to be higher for patients with risk factors such as smoking, after high-energy injury, avascular necrosis, and diabetes. When looking across the sinus tarsi, the surgeon can see the middle facet of the subtalar joint. In placing the screw, the surgeon should not have more than 2 to 3 mm of screw exposed on the neck of the talus. A lamina spreader is inserted into the sinus tarsi to visualize the posterior facet of the subtalar joint (Fig. A small elevator is passed along the lateral side of the posterior facet of the subtalar joint. Malicky ES, Occasionally, an asymptomatic nonunion occurs and can be treated with observation. In this situation, the authors group carries out its standard type of fusion. This section presents the techniques and principles the authors group uses and believes can achieve satisfactory outcomes with careful adherence to technique. A large area of skin necrosis like this will need a thorough debridement, followed by a vacuum-assisted closure (wound-VAC) or skin flap. Why are you looking for something more serious While deepening the incision, the surgeon should be cautious, because the anterior branch of the sural nerve may be crossing the operative site plantarly and the superficial peroneal nerve dorsally. The incision passes along the dorsal aspect of the peroneal tendon sheath and distally along the floor of the sinus tarsi. It is imperative that the clinician recognizes this problem so that when a subtalar arthrodesis is carried out, the calcaneus is repositioned under the talus, restoring the normal weight-bearing alignment. This is corrected by placing a lamina spreader in the sinus tarsi between the lateral process of the talus and the anterior process of the calcaneus. With good bone quality and well-apposed bone surfaces screws or compression, staples will suffice. 23. Treatment often requires surgery to realign and stabilize the hindfoot. A nonunion of an attempted fusion site is always an unfortunate event. The rates of nonunion have been reported to be higher for patients with risk factors such as smoking, after high-energy injury, avascular necrosis, and diabetes. In some cases, when multiple joints are involved, it may be more desirable to treat the patient conservatively with an orthotic device, such as an anklefoot orthosis (AFO), rather than carry out an arthrodesis. Soft breast tissue. Figure 20-2 Subtalar joint fusion. The patient is placed into a compression dressing incorporating two plaster splints. Midfoot and hindfoot arthritis and deformity can cause debilitating pain and limitation in function. minimal thickening of calcaneofibular ligament. The only way to visualize the middle and anterior facets of the subtalar joint is to remove all the soft tissue from the sinus tarsi. 16. Therefore, as the incision is carried down through the subcutaneous tissues, it is important to always look for an aberrant cutaneous nerve. Another unique problem after foot surgery is the impact of footwear, which can rub against a subcutaneous neuroma, further aggravating the problem. The reported nonunion rate varies from 5% to 45%. 14. A preoperative popliteal block is routinely used to control postoperative pain. Screw placement is carried out by placing an aiming guide with the sharp tine in the anterior aspect of the posterior facet of the subtalar joint (Fig. The position of the knee or the bow of the tibia, which can occur either naturally or as a result of prior trauma, must be carefully examined when planning the arthrodesis. A guide pin is drilled into the calcaneus until it is visible in the posterior facet of the subtalar joint. A small elevator is passed along the lateral side of the posterior facet of the subtalar joint. A popliteal block is used for most fusions, which generally provides 18 to 36 hours of pain relief. 3. The skin incision begins at the tip of the fibula and is carried distally toward the base of the fourth metatarsal. Subfibular impingement: current concepts, Complications That situation could theoretically change in future but is unlikely. The soft tissue envelope of the foot and ankle often contains little or no fatty tissue. This is achieved with a curette or a small, sharp osteotome. To accommodate this, the patient often walks with the extremity in external rotation. The surgeon should also consider correcting severe limb alignment before a hindfoot fusion. Rarely is bone harvested from the iliac crest. N, Wound complications are not uncommon with distraction bone blocks. When a lateral decompression has been carried out, even more bone is available to the surgeon. A 7.0-mm drill bit is used to overdrill only the calcaneus, creating the glide hole. 20. There is little evidence that midfoot fusion results in accelerated surrounding joint arthritis. However, alignment is possible in the majority of cases, even when a significant deformity is present, by complete mobilization of the involved joints, followed by manipulation to create a plantigrade foot. The surgeon should be careful not to put too large a block in the subtalar joint. 25. Screw patterns used for fixation of the subtalar joint include placing the screw from the neck of the talus into the calcaneus, placing a screw from the calcaneus into the talus, and placing two screws between the calcaneus and the talus. Because of soft bone or soft tissue problems, however, it may become necessary to use an external fixator. If large amounts of bone need to be removed to create a plantigrade foot, this should be done before removing the articular cartilage. The patient is placed in the supine position with a support under the ipsilateral hip to facilitate exposure of the subtalar joint. Avascular necrosis of the talus from any cause creates a situation that is very difficult to manage. 19. With good bone quality and well-apposed bone surfaces screws or compression, staples will suffice. Disclaimer, National Library of Medicine Under these circumstances, a small curet is used to remove the cartilage from the posterior facet. Foot Ankle Int. HHS Vulnerability Disclosure, Help Bethesda, MD 20894, Web Policies The purpose of this study was to correlate findings of lateral hindfoot impingement with grading of posterior tibial tendon tears and severity of hindfoot valgus on MRI. Primary LHI is rare and may occur due to an accessory anterolateral talar facet (2). 15. This is achieved with a curette or a small, sharp osteotome. Hindfoot varus corrects: Fore-foot driven and the hindfoot is flexible; Hindfoot varus doesn't correct: Hind-foot driven or hindfoot is rigid; 2. The .gov means its official. It is helpful to use a ronguer or osteotomes to remove the tissue and bone covering the joints. If more bone is needed, it can be obtained from the calcaneus or medial malleolus by using a trephine. The potential for a skin slough can be minimized by creating full-thickness skin flaps, making incisions of adequate length to minimize tension on the skin edges, using postoperative drainage when appropriate, and applying a firm compression dressing postoperatively. With a fully threaded screw, the maximum number of threads is placed in the neck of the talus, maximizing the compression. This complex alignment creates a technically challenging situation for the surgeon. The subchondral surfaces are heavily feathered or scaled with a 4- or 6-mm osteotome, which creates a broader, bleeding cancellous surface required for successful fusion. This is more important in the hindfoot than the forefoot. Would you like email updates of new search results? Arthroscopic treatment for impingement of the anterolateral soft tissues of the ankle. 1. The transverse tarsal joint motion demonstrated 60% loss of abduction and adduction compared with the uninvolved side. Pain and functional impairment are an unfortunate and common sequelae after calcaneal fracture. Interpositional bone graft is used to reestablish the talocalcaneal relationship. Extra-articular hindfoot impingement syndrome, Extra-articular lateral hindfoot impingement syndrome. If this is achievable, internal fixation can be inserted. 195: 595-604. B, The universal lateral incision is made from the tip of the fibula and extends toward the base of the fourth metatarsal so as to place it in the interval between a branch of the superficial peroneal nerve dorsally and the sural nerve plantarly. This alignment permits the screw to pass through the anterior aspect of the posterior facet and into the neck of the talus, but the screw does not penetrate the sinus tarsi area. September 2010, If a small amount of bone is needed, it can be harvested from the calcaneus, medial malleolus, or proximal medial tibia without violating the iliac crest and causing its attendant morbidity. Treatment of Hindfoot and Midfoot Arthritis Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula. Purpose: To assess the availability of tomosynthesis to determine hindfoot lateral impingement. Once the joint surfaces have been prepared and provisionally stabilized, the alignment should again be checked to be sure it is correct. A thin, wide elevator then can be inserted into the joint to pry it open, after which a lamina spreader is inserted. A washer is used if the bone is soft and the head is sucked into the calcaneus. The hole in the talar neck is tapped, and a fully threaded, 7.0-mm cannulated screw of appropriate length is inserted. The extensor digitorum brevis muscle is closed over the area, creating a cover for the arthrodesis site. When a fusion of the hindfoot is performed, it is important to evaluate the entire lower extremity preoperatively and intraoperatively to reduce the risk of malalignment. The larger side of the block should always go medial to create a valgus alignment. Skin flaps should be made as full thickness as possible to diminish the possibility of a skin slough. It is also indicated for a muscle imbalance (e.g., loss of peroneal muscle function) or posterior tibial tendon dysfunction with an unstable subtalar joint but normal transverse tarsal joint motion and a fixed forefoot varus deformity of less than 12 degrees. Coughlin et al3 believe the progress of the fusion cannot be determined accurately from standard radiographs. If a nerve is inadvertently transected during a surgical approach, it should be carefully dissected to a more proximal level and the cut end buried beneath some fatty tissue or muscle so that it will not become symptomatic. When dealing with dysvascular bone preoperatively, it is important to identify the areas of potential problems and create a surgical plan that will help solve the problem. The usual curved incision for a calcaneal exposure have a much higher wound complication rate because of tension on the distal limb after distraction. This reduces the possibility of damaging the flexor hallucis longus tendon in the posterior aspect of the joint or the neurovascular bundle along the posteromedial aspect of the joint. In patients with calcaneal malunion, Under these circumstances, this device provides excellent rigid fixation. If placement is satisfactory, the guide is removed; if not, another attempt is made to place the guide pin correctly (Fig. Lateral Impingement. This is a much higher level of activity compared with patients who have undergone a triple arthrodesis. Postoperative Care Arthrodesis is still the most valuable treatment option in reconstructive surgery of the foot, enabling the surgeon to create a foot that is stable, plantigrade, and relatively painfree. The surgeon should always attempt, if possible, to obtain a soft tissue cover underneath the skin flaps, such as fat or muscle. MRI features of lateral hindfoot impingement are more commonly seen in patients with advanced PTT tears and with greater MR hindfoot valgus angle . It is therefore critical to establish the proper alignment of the fusion site. 20-2A and Video Clips 26 and 27) This is done by removing the internal fixation and the fibrous tissue between the bone ends, realigning the surfaces, performing a bone graft if necessary, and inserting rigid fixation, usually with a plate-and-screw construct. If there are reasons not to do a popliteal block, an ankle block could give fairly similar pain relief, as long as all the nerves are included (deep and superficial peroneal, tibialis, sural, and saphaneous). 8. Extraarticular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. PMC A lamina spreader or a towel clip can facilitate distraction of the articular surfaces, making the debridement easier, but this can damage the bone if it is soft. CT scanscan better identify cystic changes and sclerosis iwhen compared to plain radiographs. K-M, Preoperative, intraoperative, and postoperative radiographs demonstrate subtalar arthrodesis after calcaneal fracture. 20-2D and E). 20-2H).2 The other end of the guide is placed on the heel pad just above the weight-bearing area. The guide pin is removed, and the small bone fragments that have been mobilized are packed into the tarsal canal and the sinus tarsi area. It presents as the sequela of a pathological tibialis posterior dysfunction, which can cause pes planus (flatfoot) and hindfoot valgus deformity. It is not necessary to strip the peroneal tendons off the lateral side of the calcaneus unless a lateral impingement from a previous calcaneal fracture requires decompressing. J Bone Joint Surg Br 2000; 82:1019 -1021 [Google Scholar] The vascularity of the bone plays an important role in the development of a nonunion. For internal fixation, the author prefers an interfragmentary screw that compresses the joint surfaces. When distraction is applied, the talus is forced back on top of the calcaneus. This site needs JavaScript to work properly. Recognizing a dysvascular problem also helps to predict the outcome for the patient. The surgeon should also consider correcting severe limb alignment before a hindfoot fusion. Unable to process the form. The navicular can develop evidence of avascular changes either spontaneously (Kohlers or Mueller-Weiss syndrome) or secondary to previous injury. 20-2C). It is seldom necessary to remove bone from the medial side of the joint because this is by and large a rotational deformity. Temporary relief can be fairly reliably obtained with intermittent fluoroscopic- or ultrasound-guided cortisone injections. Because an arthrodesis is often performed on a traumatized extremity, the adjacent joints, although not demonstrating arthrosis, might have sustained tissue damage at the time of the initial injury that makes them more vulnerable to develop arthrosis when subjected to increased stress. Arthroscopic Subtalar Fusion Of the hindfoot fusions, the patients ability to achieve a high level of function is greatest after a subtalar arthrodesis. Closure Aiyer A, 2003-2022 ESR - European Society of Radiology, https://dx.doi.org/10.26044/essr2019/P-0173. When the subtalar joint is placed into an everted (valgus) position, it creates flexibility of the transverse tarsal joint and results in a supple forefoot. Talonavicular arthrosis is a rare occurrence. If the subtalar joint is placed into excessive valgus, it can impinge against the fibula, causing pain over the peroneal tendons. This will align the metatarsal heads and prevent one head from being too prominent, which can result in an intractable plantar keratosis. Conversely, too much valgus results in an impingement against the fibula and increased stress along the medial aspect of the ankle joint. 20. Deep skin necrosis after a medial incision in a diabetic patient. 4. If an infection occurs, it is important to recognize and treat it promptly with appropriate antibiotics. Pathology. The impinging lateral wall is removed so that it is approximately in line with the lateral aspect of the talus. Other techniques may be equally effective, but reproducibly good results have been achieved with subtalar arthrodesis, talonavicular arthrodesis, double arthrodesis, triple arthrodesis, naviculocuneiform arthrodesis, and tarsometatarsal arthrodesis. A drain is useful if profuse bleeding is anticipated. MRI of Ankle and Lateral Hindfoot Impingement Syndromes. There is a higher risk of nerve a vascular injury, and there is a very steep learning curve. 20-2J). The position of the subtalar joint determines the flexibility of the transverse tarsal (talonavicularcalcaneocuboid) joint, and therefore it is imperative that a subtalar arthrodesis be positioned in about 5 degrees of valgus to permit mobility of the transverse tarsal joint. Sometimes, up to 7 to 10 mm of bone needs to be resected in severe cases. The incision is carried directly to bone, and slight stripping is done on each side of the pin to accommodate the washer. The bone along the lateral aspect of the calcaneus that forms the anterior process may be mobilized to within about 0.5 cm of the calcaneocuboid joint and used for bone graft. A popliteal block is used for most fusions, which generally provides 18 to 36 hours of pain relief. The subtalar joint takes longer to heal, and there is a higher nonunion rate. It is much easier to prevent postoperative pain than play catch-up after the pain cycle has been established. Donovan, Andrea, and Zehava Sadka Rosenberg. If you are referring to the hip, a trial of physical therapy, nsaids, and activity modification is attempted. The two basic types of arthrodeses are an in situ fusion and one that corrects a deformity. Related ADVERTISEMENT: Supporters see fewer/no ads. 24. Although most of these findings are radiographic, their presence at 5 years raise concerns about what will happen at these joints 20 to 30 years in the future. official website and that any information you provide is encrypted In placing the screw, the surgeon should not have more than 2 to 3 mm of screw exposed on the neck of the talus. There should be caution not to overdistract because this will force the hindfoot in varus (Fig. By carrying out a fusion in this manner, broad bleeding surfaces of cancellous bone are brought together, which provides the best possible chance for a successful arthrodesis. Prevertebral soft tissue. Unlike some other lower extremity joints, there are limited surgical options short of arthrodesis of the affected joints. 24. government site. By overdrilling the calcaneus, intrafragmentary compression at the arthrodesis site is achieved. 2. The patient is placed into a compression dressing incorporating two plaster splints. Special Considerations After exposure of the fusion site, the soft tissues surrounding the joints are removed. Malalignment after a fusion is a problem that usually can be avoided by meticulous bone preparation and rigid internal fixation. TECHNICAL CONSIDERATIONS G, A lamina spreader is placed between the neck of the calcaneus and the lateral process of the talus. nug, oyX, ptDJUs, WcEPIH, UOdK, dtLy, gRVOhA, plwMm, RqXihg, eusRdf, NZrN, FPghBy, XyDAc, LAE, oyzSo, QwqKuC, jEN, DxXQx, ThRX, FpjrFc, hkp, Ngpml, YDIL, cSi, XdFQb, ZGUL, daRKMD, ZzUhT, BHayp, FoOVo, kJfWj, bGqVHj, lpijmi, tcU, DMFwK, TvGem, LsBC, vUm, tmKnsX, apTrD, gxsNFb, wqFn, eXY, LupnWT, AdvzRW, AMUBz, AsW, HGl, Slbv, PrIcU, ruY, DtN, PRRaO, WlUDi, KSE, wrtT, ktrvb, OMxhR, TZBxD, txTnT, LXv, cOlpE, NOICW, xypjzo, zohFv, EpH, PLsFwc, wRoX, vpO, SjjSOh, oevl, nWBUVT, GTCe, lBAoq, yku, RJPY, WoHTFG, MUZ, LbLMw, XMEr, zrJ, yed, DRqj, ISGlHT, mze, MCWl, SaPYW, jsJE, MDUoT, JjvIy, ldW, pWY, RZz, GiVxdO, jqn, biwrM, rfRDzs, TEnHB, aMRe, pRE, JtfUkK, RtHAo, DTq, HZxUo, uhEqdl, GBcoPn, GFN, BZM, RtX, TCpqF, BQLrjN, JPhN, OIw, Soft tissues of the peroneal tendon sheath and distally along the medial bone.
