Objective: To compare the effectiveness of talonavicular-cuneiform joint fusion with iliac bone grafting and without bone grafting in the treatment of Müller-Weiss diseases (MWD)., Methods: The clinical data of 44 patients (44 feet) with MWD who received talonavicular-cuneiform joint fusion between January 2017 and November 2022 and met the selection criteria was retrospectively analyzed. Among them, 25 patients were treated with structural iliac bone grafting (bone grafting group) and 19 patients without bone grafting (non-bone grafting group). There was no significant difference ( P >0.05) in age, gender composition, body mass index, disease duration, affected side, Maceira stage, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, anteroposterior/lateral Meary angle, and Pitch angle between the two groups. Operation time, operation cost, and postoperative complications were recorded in the two groups. AOFAS and VAS scores were used to evaluate the function and pain degree of the affected foot. Meary angle and Pitch angle were measured on the X-ray film, and the joint fusion was observed after operation. The difference (change value) of the above indexes before and after operation was calculated for comparison between groups to evaluate the difference in effectiveness., Results: The operation was successfully completed in both groups, and the incisions in the two groups healed by first intention. The operation time and cost in the bone grafting group were significantly more than those in the non-bone grafting group ( P <0.05). All patients were followed up. The median follow-up time was 41.0 months (range, 16-77 months) in the non-bone grafting group and 40.0 months (range, 16-80 months) in the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case, internal fixation stimulation in 2 cases, and pain at the iliac bone harvesting area in 1 case of the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case and muscle atrophy of the lower limb in 1 case of the non-bone grafting group. There was no significant difference in the incidence of complications between the two groups ( P >0.05). At last follow-up, the AOFAS scores of the two groups significantly improved when compared with those before operation, while the VAS scores significantly decreased, the anteroposterior/lateral Meary angle and Pitch angle significantly improved, and the differences were significant ( P <0.05). There was no significant difference in the change values of outcome indicators between the two groups ( P >0.05). There was no delayed bone union or bone nonunion in both groups, and joint fusion was achieved at last follow-up., Conclusion: In the treatment of MWD, there is no significant difference in effectiveness and imaging improvement of talonavicular-cuneiform joint fusion combined with or without bone grafting. However, non-bone grafting can shorten the operation time, reduce the cost, and may avoid the complications of bone donor site.

Objective: To explore the effectiveness of modified internal fixation and fusion in treatment of type Ⅱ painful accessory navicular (PAN) in adults., Methods: Between January 2016 and December 2017, 29 patients (37 feet) with type Ⅱ PAN were treated with modified internal fixation and fusion. There were 12 males and 17 females with an average age of 41.4 years (range, 18-50 years). The injury caused by sprain in 24 cases and no obvious inducement occurred in 5 cases. All patients received conservative treatment for more than 6 months with no significant improvement. The effectiveness was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score before operation and at last follow-up. The inclination angle of calcaneus, the first metatarsal angle of talus, the inclusion angle of talonavicular joint, and the second metatarsal angle of talus were measured on X-ray films., Results: Superficial infection of incision occurred in 1 case after operation, and the incision healed after enhanced dressing change. The incisons of the other patients healed by first intention. There was no deep infection or osteomyelitis. All patients were followed up 12-33 months (mean, 25.1 months). X-ray films showed that the articular surfaces healed at 2-5 months after operation, with an average of 3.4 months. No loosening or rupture of internal fixator was found during the follow-up. At last follow-up, the pain, function, alignment scores, and total score of AOFAS were significantly improved when compared with those before operation ( P <0.05). The inclusion angle of talonavicular joint, the first metatarsal angle of talus, and the second metatarsal angle of talus were also significantly improved when compared with those before operation ( P <0.05). But there was no significant difference in the inclination angle of calcaneus between pre- and post-operation ( t =1.097, P =0.276)., Conclusion: Modified internal fixation and fusion in treatment of type Ⅱ PAN can effectively relieve the symptoms and obtain good recovery of feet function with less complications.

Objective: To evaluate the short-term effectiveness of talonavicular arthrodesis for Müller-Weiss disease., Methods: Between May 2013 and February 2015, 13 patients with Müller-Weiss disease were treated with talonavicular arthrodesis. There were 11 females and 2 males with an average age of 59 years (range, 42-67 years). The disease duration was 8-20 years (mean, 13 years). According to Maceira stage, there were 7 cases of stage Ⅲ, 6 cases of stage Ⅳ. The foot longitudinal arch height measured on weight-bearing X-ray films was (43.1±1.8) mm; the Meary angle and talocalcaneal angle measured on lateral X-ray films were (-2.8±2.3)° and (5.8±2.4)°, respectively; the calcaneal valgus angle measured on Saltzman position X-ray films was (-2.0±0.7)°. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.5±12.4, and visual analogue scale (VAS) score was 7.3±1.5., Results: All the patients were followed up 14-39 months (mean, 20 months). The symptoms of foot pain and intermittent claudication disappeared in all patients. All cases achieved bony union, the fusion time was 12-16 weeks (mean, 13 weeks). There was no complications such as wound infection, skin necrosis, or internal fixator broken. At last follow-up, the foot longitudinal arch height, Meary angle, talocalcaneal angle, and calcaneal valgus angle were (52.5±2.2) mm, (1.3±2.2)°, (16.5±3.7)°, and (0.4±0.7)°, respectively; the AOFAS score and VAS score were 83.8±9.1 and 1.0±0.4, respectively; all were significantly improved when compared with preoperative ones ( P <0.05)., Conclusion: If the subtalar and calcaneocuboid joints are relatively healthy, talonavicular arthrodesis may be a reliable and effective surgical option for Müller-Weiss disease that is resistant to conservative treatment.

Objective: To evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot., Methods: Seven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function., Results: All patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring., Conclusion: Tarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.

Accessory navicular source flatfoot is one of the foot deformity of clinical common disease,its treatment method is more controversial, differences in clinical efficacy of different surgical methods, according to accessory navicular source flatfoot symptoms of surgical treatment,there is no uniform standard, around a pair of accessory navicular excision how to reconstruct the arch produced a series of operation methods, the clinical curative effect of different operative methods produce also different, how to develop the operation strategy, choose operation method, and after acessory navicular excision whether to rebuild posterior tibial tendon, how to rebuild, the problems such as how to rebuild is the research hotspot and difficulty, looking forward to further research.

Objective: To investigate the effectiveness of double arthrodesis to correct flatfoot deformity with pes valgus., Methods: Between May 2009 and May 2012, 12 patients with flatfoot deformity and pes valgus were treated using subtalar and talonavicular joints arthrodesis through a single medial incision approach. There were 5 males and 7 females with an average age of 53.3 years (range, 21-78 years), including 5 left feet and 7 right feet. Of them, 11 cases had posterior tibial tendon dysfunctions; 6 cases were at Johnson-Strom stage III, 5 cases at stage II(c); and 1 case had tarsal coalition. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 48.75 ± 3.46 and 6.08 ± 1.14, respectively., Results: The mean operation time was 85.6 minutes (range, 65-125 minutes). Eleven patients were followed up for 19.4 months on average (range, 13-30 months). All of the cases obtained primary healing of incision, with no complication of infection and nerve or blood vessel injury. X-ray film showed that the mean time of bone union was 9.8 weeks (range, 7-18 weeks): no bone nonunion occurred. No loosening or breakage of internal fixation was observed. Pain occurred at the calcaneal-cuboid joint (1 case) and at fixation site (1 case), and was relieved after symptomatic treatment. The mean AOFAS score and VAS score were significantly increased to 81.36 ± 2.98 and 0.72 ± 0.11 respectively, showing significant differences when compared with preoperative scores (t = 19.946, P = 0.000; t = 16.288, P = 0.000)., Conclusion: Subtalar and talonavicular joints arthrodesis by a single medial incision approach is a useful alternative to triple arthrodesis for the correction of flatfoot deformity with pes valgus.

Objective: To evaluate the clinical outcome of accessory navicular fusion for treatment of the painful accessory navicular bone of type II in adults., Methods: From June 2006 to June 2012, a total of 38 feet (in 35 adult patients) with painful accessory navicular with type I underwent an fusion operation of the primary and accessory navicular bones,including 26 males and 9 females with a mean age of (32.4±7.3) years old ranging from 18 to 44 years old. The course of disease ranged from 3 to 10 months. The perioperative complications and radiological outcomes were observed and recorded. The foot function before and after operation were assessed by the American Orthopedic Foot and Ankle Society (AOFAS) midfoot score, and the easement of the pain was evaluated by visual analog score (VAS)., Results: Two patients had transient superficial inflammation of the incision, no obvious perioperative complications occurred. All patients were follow-up for (53.5±14.7) months (12 to 84 months). Bone union was confirmed on plain radiography in 32 cases (35 feet). The mean time from the operation to union was (13.7±2.3) weeks (9 to 18 weeks). Postoperative pain VAS score was improved obviosly than preoperative (V=12.14,P< 0.01). The talar-to-first metatarsal angle [(9.4±3.5)° vs (8.3±2.7)°, t=0.736, P>0.05)], calcaneal tilt angle [(17.7±2.2)° vs (18.9±3.4)°, t=0.794, P>0.05],talonavicular uncoverage angle [(14.3±3.4)° vs(12.5?4.6)°,t=0.947, P>0.05) ],and height of the first tarsometatarsal joint [(14.8±3.1) mm vs (15.9±2.8) mm,t=0.814,P>0.05)] before and after operations had no statistic difference. The AOFAS midfoot score was improced from preoperative 45.6±5.3 to postoperative 82.5±7.4 (t=3.214,P< 0.01)., Conclusion: For the painful accessory navicular bone of type II in adults, if the patient has a large navicular bone and not complicated with rigid flatfoot, once the conservative treatment fails, fusion of the primary and accessory naviculars may be a successful intervention. Overall, the procedure provides reliable pain relief, definite foot function improvement, and good patient satisfaction.

Objective: To investigate the application of the plantar horn shaped fasciocutaneous perforator flaps for the reconstruction of the defects on heel and fore plantar., Methods: The proximal end of the plantar fasciocutaneous perforator flaps were at the edge of defects. The deep fascia was cut off at the both sides of flaps. The plantar fascia should be included into the flaps. Then the flaps were rotated to cover the defects, containing two or three perforators. If necessary, the original supplying vessels could be cut off to facilitate the advancement of flaps., Results: From Jan. 2010 to Oct. 2012, 7 cases with plantar defects were treated with the horn shaped perforator flaps. The defects size ranged from 1.5 cm x 2.0 cm to 4.0 cm x5. 0 cm with the size of the flaps ranging from 7 cm x 3 cm to 13 cm x 7 cm. All the flaps survived completely with primary healing both on donor and recipient sites. The flap color, texture, function and appearance were satisfactory during the follow-up period of 3-24 months., Conclusions: The plantar horn shaped perforator flap can reconstruct the defects at plantar weight-bearing area with the similar thick skin tissue, which facilitates the functional reconstruction. No skin graft is necessary for the defect at donor site.

Objective: To evaluate therapy effect of radiofrequency in the treatment of painful heel syndrome under arthroscopy., Methods: From January 2006 to December 2011, 13 patients with painful heel syndrome being admitted into our hospital were studied. There were 5 males and 8 femals, ranging in age from 35 to 68 years. All these surgeries were performed under local anesthesia. After constructing a man-made lacouna in the subcutaneous tissue above plantar fascia, a medial and a lateral portal were established on both sides of plantar fascia and at the anterior edge of calcaneal tuberosity. Hyperplasia and torn fiber tissue of plantar fascia, and plantar calcaneal bursa were removed with radiofrequency probe under arthroscopy. Then penetration of the plantar fascia was carried out in a reticulation-shaped pattern with a special radiofrequency probe TOPAZ. Each patient was assessed with VAS pain evaluation criteria and AOFAS ankle-hindfoot score system (AOFAS-AH) before and after operation. All the patients were followed up, and the duration ranged from 6 to 12 months., Results: All the 13 patients got excellent recovery with their heel pain relieved significantly. VAS score was 8.71 +/- 1.64 before operation, 6.27 +/- 2.53 at the 1st month after operation, and 2.30 +/- 2.69 at the 6th month after operation. AOFAS-AH score was 56.43 +/- 3.72 preoperation, 68.15 +/- 7.38 at 1st month post operation, and 84.51 +/- 2.93 at 6th month after operation. There were no perioperative and postoperative complications related to the procedure, such as blood vessel and nerve injury, and infection., Conclusion: Plantar fasciitis and plantar calcaneal bursitis are main factors of painful heel syndrome. Due to advantages of being easy to operate, having definite effect and no use to do spur removal or plantar fasciotomy. Endoscopy assisted plantar calcaneal bursa removal and plantar fascia penetration by radiofrequency technique can be a satisfactory treatment method for painful heel syndrome.

Objective: To explore perioperative management and postoperative effectiveness of hemophilia induced lesions of the foot and ankle., Methods: Between June 1998 and February 2012, 10 cases (12 feet) of hemophilia induced lesions of the foot and ankle were treated with surgery, including 9 cases (11 feet) of hemophilia A and 1 case (1 foot) of hemophilia B. Single foot was involved in 8 cases and both feet in 2 cases, including 3 left feet and 9 right feet. All were males, aged from 13-41 years (mean, 22.6 years). Disease duration was 5-84 months (mean, 32.2 months). Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.2 +/- 21.1. Short Form 36 Health Survey Scale (SF-36) score was 45.4 +/- 20.0. All patients were given clotting factors (2 000-3 500 U) for pre-experiment and clotting factors substitution therapy was performed perioperatively. Four cases (4 feet) underwent arthrodesis, and 7 cases (8 feet) underwent Achilles tendon lengthening/tendon transposition (1 patient underwent tendon lengthening on the left foot and arthrodesis on the right foot)., Results: The operation time was 65-265 minutes (mean, 141.1 minutes); 1 case had 400 mL blood loss and 200 mL autogenous blood transfusion, the other cases had less than 50 mL blood loss and no blood transfusion. Wounds healed by first intention in all patients, no postoperative infection, deep vein thrombosis, or other complications occurred. All cases were followed up 6 months to 14 years and 3 months (median, 22 months). The X-ray films at last follow-up showed the patients undergoing arthrodesis obtained complete joint fusion. AOFAS scores at postoperative 6 months and last follow-up were 78.8 +/- 14.7 and 75.8 +/- 14.5, respectively; SF-36 scores were 76.6 +/- 13.1 and 75.5 +/- 13.2, respectively; and significant differences were found when compared with preoperative scores (P < 0.05), but no significant difference between postoperative 6 months and last follow-up (P > 0.05)., Conclusion: For patients with hemophilia induced lesions of the foot and ankle, surgical treatment could relieve foot and ankle pain and improve the function. Clotting factors pre-experiment at preoperation and substitution therapy at perioperation can reduce the risk of severe postoperative hemorrhage.

Objective: To discuss operative methods and effects for Müller-Weiss disease., Methods: From March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation., Results: Ten feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision., Conclusion: Operations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.

Objective: To analyze the excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular for the treatment of flatfoot related with accessory navicular and to evaluate its effectiveness., Methods: Between May 2006 and June 2011, 33 patients (40 feet) with flatfoot related with accessory navicular were treated. There were 14 males (17 feet) and 19 females (23 feet) with an average age of 30.1 years (range, 16-56 years). All patients had bilateral accessory navicular; 26 had unilateral flatfoot and 7 had bilateral flatfeet. The disease duration ranged from 7 months to 9 years (median, 24 months). The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-midfoot score was 47.9 +/- 7.3. The X-ray films showed type II accessory navicular, the arch height loss, and heel valgus in all patients. All of them received excision of accessory navicular and reconstruction of posterior tibial tendon insertion on navicular with anchor., Results: All patients got primary wound healing without any complication. Thirty patients (36 feet) were followed up 6-54 months with an average of 23 months. All patients achieved complete pain relief at 6 months after surgery and had good appearance of the feet. The AOFAS ankle-midfoot score was 90.4 +/- 2.0 at last follow-up, showing significant difference when compared with preoperative score (t=29.73, P=0.00). X-ray films showed that no screw loosening or breakage was observed. There were significant differences in the arch height, calcaneus inclination angle, talocalcaneal angle, and talar-first metatarsal angle between pre-operation and last follow-up (P < 0.01)., Conclusion: The excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular is a good choice for the treatment of flatfoot related with accessory navicular, with correction of deformity, excellent effectiveness, and less complications.

Objective: To treat heel pain with small needle-knife according to its classification,so as to improve the therapeutic effects., Methods: From August 2005 to December 2008, 200 patients with 266 heel pain were treated according to the author's classification standards. There were 83 males and 117 females, ranging in age from 26 to 72 years, with a mean age of 46 years; the course of the disease ranged from 3 to 36 months, averaged 6.8 months. According to the classification:67 heels with plantar fasciitis type, 61 heels with calcaneal bursitis type, 36 heels with plantar fat pad inflammation-based type, 6 heels with calcaneus high pressure-type, 21 heels with nerve compression type, 75 heels with mixed type. All the patients were treated with small needle-knife by using different methods according to its classification., Results: After 1 month treatment, among the patients with plantar fasciitis-type, 31 heels got an excellent result,36 good;among the patients with calcaneal bursitis type, 32 heels got an excellent result, 29 good; among the patients with plantar fat pad inflammation-based type, 9 heels got an excellent result, 20 good, 4 poor and 3 bad; among the patients with calcaneus high pressure-type, 1 patient got an excellent result, 3 good and 2 poor; among the patients with nerve compression type, 11 heels got an excellent result, 8 good, 1 poor and 1 bad; among the patients with mixed type, 16 heels got an excellent result, 46 good, 5 poor and 8 bad. At the 6th month after treatment, among the patients with plantar fasciitis-type, 21 heels got an excellent result, 40 good,5 poor and 1 bad; among the patients with calcaneal bursitis type, 30 heels got an excellent result, 28 good and 3 poor; among the patients with plantar fat pad inflammation-based type, 15 heels got an excellent result, 18 good, 2 poor and 1 bad; among the patients with calcaneus high pressure-type, 0 patient got an excellent result, 3 good and 3 poor;among the patients with nerve compression type,7 heels got an excellent result, 11 good, 1 poor and 2 bad; among the patients with mixed type, 10 heels got an excellent result, 45 good, 11 poor and 9 bad., Conclusion: The causes of heel pain can't be explained by using single pathogenesy,and also can't be treated with one method. The patients with calcaneal pain should be treated with different methods according to classification of heel pain, and thus the therapeutic effects can be improved.

Objective: To observe and evaluate the clinical effects of surgical treatment for the accessory navicular syndrome with simple excision., Methods: From November 2006 to December 2008, 23 patients (twenty-five feet) with accessory navicular syndrome received simple excision of the accessory navicular bone. The chief complains were intermittent pain of feet after running or walking. Physical examination showed local tenderness on palpation in the region of the navicular bone. X-ray or CT showed there was an accessory navicular bone. The present history ranged from 6 months to 12 years. There were 14 males and 9 females. The mean age was 14.6 years, ranging from 8 to 35 years. About 2 cm long incision was made at the tip of the medial prominence of the navicular bone. After partial dissection of the posterior tibial tendon, the accesssory navicular bone was exposed and excisied. The prominence of the tuberosity of the navicular bone was cut and shaved. The posterior tibial tenden was repaired before closing the wound. The foot was immobilized with cast or brace in inversion position and no weight-bearing for 2 weeks. Strenuous jumping or dancing must be avoided in 3 months after surgery. The patients with residual symptoms and signs received physical therapy and an arch support for shoes without flatfoot deformity., Results: The average clinical follow-up during was 12 month (ranged, 3 to 18 months). The excellent results in 21 feet and good in 4 feet (3 feet with mild flat deformity and 1 foot with old sprain injury). The average hospital stay was 5 days and no wound infection occurred. All patients resumed the normal life and study after operation., Conclusion: Surgical treatment of the accessory navicular syndrome with simple excision has the advantages of less invasive to the posterior tibial tenden and the medial longitudinal arch of the foot, shorter time of immobilization of the foot and stay in hospital, small incision and good clinical results. This procedure is one of the best selective treatments for the accessory navicular syndrome, especially for the patients without flatfoot deformity and old sprain injury.

Objective: To evaluate therapeutic effects of traditional Chinese drug soaking,continual irrigation and focus elimination for foot osteomyelitis complicated with massive skin defect and denervation., Methods: There were 25 males and 28 females in the study. All the patients suffering from foot osteomyelitis complicated with massive skin defect and denervation were treated with comprehensive therapy including preoperative traditional Chinese drug soaking, skin release, focus elimination,continual irrigation, and two-stage suture if necessary. Among the patients, there were 42 cases of left foot and 11 cases of right one. Fifty-one patients complicated with skin defect and sinus tract,only 2 patients complicated with skin defect. There were 48 patients with denervation caused by spina bifida, 5 patients by other causes., Results: The follow-up duration was from 1 to 12 years,the mean time was about 5 years. Osteomyelitis recurred in 3 cases and skin defect reoccurred in original position in 9 cases., Conclusion: The methods of traditional Chinese drug soaking, continual irrigation and elimination of focus have good effects for foot osteomyelitis complicated with massive skin defect and denervation. To some degree,this therapy may avoid skin flap transplantation, bone graft and amputation. It deserves further studies and promotion.

Forty-four patients with acute skin loss or chronic scarring around ankle were treated by skin transplantation for covering the skin defect or replacing the scar tissue as well as restoring sensation. 13 of them were treated by pedicled sensorineural island flap, 23 by sensorineural free flap, and 8 transplanting sensorineural band into the skin flap. Follow-up study for 2 to 6 years revealed that sensation of pain, temperature and touch was normal in each flap, with 2-point discrimination of 20 to 60 mm. Trophic ulcer never developed in any case though on weight-bearing at least for 6 hours daily. Block of the sensory nerve proximal to the flap with 2% procaine in 6 cases resulted in senselessness over the flap area. The surgical procedures and the merits of every one of the three types of operation were described and discussed.
