Objective To summarize the clinical effects of the repairing methods for deep wounds of the foot and ankle. Methods From March 2002 to June 2006, 49 patients with skin and deep tissue defects of the foot and ankle underwent the repairing treatment. Of them, 36 were males and 13 were females, aged 16 to 67 years( 39 years on average). The causes of injuries included mangled injury in 24 cases, high fall injury in 9 cases, cut injury in 7 cases, malignant soft tissue tumor in 5 cases, decubital ulcer in 2 cases, and electric burn in 2 cases. Of the 49 cases, 19 were in left side and 30 in right side. The defect size of skin ranged from 3 cm×2 cm to 20 cm×15 cm and deep tissue injuries were accompanied by defects of tendon and ligament in 24 cases, by damage of joint in 12 cases, and by bone defect in 9 cases, and 35 of them had infections, and 2 of them had diabetes of stage 2. The time between the injury and surgery ranged from 4 hours to 1 year.The wounds were repaired separately by local flap(3 cm×3 cm to 6 cm×4 cm) in 15 cases, local island flap(8 cm×5 cm to 12 cm×7 cm) in 25 cases, free flap(15 cm×11 cm to 24 cm×17 cm) in 4 cases, and cross leg flap(5 cm×4 cm to 8 cm×6 cm) in 5 cases. In 24 cases of defects of tendon and ligament, 15 underwent the reconstruction in one-stage operations,9 in two-satge operation.In 9 cases accompanied by bone defect, twostage bone grafting (12-64 g) was given after wound healed. Results All of the 49 flaps survived. Fortysix healed by the first intention and 3 with distal edge necrosis healed after skin grafting. Two patients with sinus formation healed after 68 months of dressing change. All the cases were followed up 6 months to 3 years, and all the flaps were well developed, the functions of the foot and ankle were satisfactory. Conclusion It can get an excellent result of appearance and function recovery repairing deep wounds of the foot and ankle with proper flaps in earlier time.
【Abstract】 Objective To explore the cause of the perioprative period compl ication of scandinavian total anklereplacement(STAR) and to summarize the experience in the treatment and prevention. Methods From March 1999 toNovember 2006, 35 patients were given total ankle replacement(TAR) with STAR system. There were 19 males and 16 femaleswith an average age of 50.5 years (27 to 68 years), including 12 cases of posttraumatic arthritis, 8 cases of osteoarthritis and 15cases of rheumatoid arthritis. All patients had pain of ankle joint, swell ing and l imitation of joint motion. The disease coursewas 9-64 months. The curative effect was estimated by Kofoed total ankle scoring system. The mean preoperative ankle scorewas 29(6-48); the mean pain score was 18.3(0-35); the mean function score was 11.7(6-18); and the mean activity score was9.2(3-12). The type of all compl ications were record, and its cause, prevetion and treatment were analyszed. Results Thirtythreepatients achieved heal ing by first intention, 2 achieved delayed union because of infection. Twenty-eight patients werefollowed up 3-80 months (mean 43.5 months). Medial malleolus fracture occurred in 2 cases, unstable ankle joint introversion in2 cases, l imitation of ankle dorsiextension in 1 case and 1 case had hypoesthesia at intermediate dorsal skin of foot and 3rd-5thmetatarsal skin without obvious dysfunction; all were treated with symptomatic medication. The postoperative mean ankle scorewas 85.5 (58-95); the mean pain score was 48.3(35-50); the mean function score was 20.7(18-30); the mean activity score was17.2(16-20). There were statistically significant differences when compared with preoperative score(P lt; 0.01). The cl inical resultswere excellent in 16 patients, good in 9 patients and fair in 3 patients. The X-ray films showed no loosening and subsidence ofprosthesis. Conclusion Although STAR can retain the functions of the operated joint, it has its special compl ications. It isimportant to obey operation principle with proficient operative technique, to strictly control surgical indication and to intensifyperioperative period treatment so as to decrease the compl ications.
Objective To explore the clinical effect of the lower rotating point super sural neurocutaneous vascular flap on the repair of the softtissue defects in the ankle and foot. Methods From May 2001 to February 2006, 24 patients with the soft tissue defects in the ankle and foot were treated with the lower rotating point super sural neurocutaneous vascular flaps. Among the patients, 15 had an injury in a traffic accident, 6 were wringedand rolled by a machine, 1 was frostbited in both feet, 2 were burned, 25 had an exposure of the bone and joint. The disease course varied from 3 days to 22 months; 19 patients began their treatment 3-7 days after the injury and 5 patients were treated by an elective operation. The soft tissue defects ranged in area from 22 cm × 12 cm to 28 cm × 12 cm. The flaps ranged in size from 24 cm × 14cm to 30 cm × 14 cm, with a range up to the lower region of the popliteal fossa. The rotating point of the flap could be taken in the region 1-5 cm above thelateral malleolar. The donor site was covered by an intermediate thickness skingraft. Results All the 25 flaps in 24 patients survived with asatisfactory appearance and a good function. The distal skin necrosis occurred in 1 flap, but healing occurred after debridement and intermediate thickness skin grafting. The follow-up for 3 months to 5 years revealed that the patients had a normal gait, the flaps had a good sense and a resistance to wearing, and no ulcer occurred. The two point discrimination of the flap was 5-10 mm. Conclusion The lower rotating point super sural neurocutaneous vascular flap has a good skin quality, a high survival rate, and a large donor skin area. The grafting is easy, without any sacrifice of the major blood vessel; therefore, it is a good donor flap in repairing a large soft tissue defect in the ankle and foot.
ObjectiveTo evaluate the level of arteriosclerosis in patients with hypertension defined by the American Heart Association (AHA) and classical diagnostic criteria. MethodsA total of 3 815 residents were enrolled in 10 communities in north Shanghai. According to the classic diagnostic criteria of hypertension (systolic blood pressure≥140 mmHg and/or diastolic blood pressure≥90 mmHg) and AHA diagnostic criteria (systolic blood pressure≥130 mmHg and/or diastolic blood pressure≥80 mmHg), the population was divided into normal blood pressure group, AHA diagnosis standard hypertension group, and classic methods of diagnosis of hypertension group. The differences in cervical-femoral pulse wave velocity (cf-PWV) and brachial-ankle pulse wave velocity (ba-PWV) among the three groups were compared. SPSS 13.0 software was then used for data analysis.ResultsCompared with the patients who met the standard criteria, patients who met AHA criteria had lower mean ages (70.2±7.4 vs. 71.4±7.9 year, P<0.001), more history of hypertension (48.8% vs. 72.7%, P<0.001) and lower body mass index (24.1±3.5 vs. 24.7±3.9 kg/m2, P<0.001), low-density lipoprotein (3.07±0.92 vs. 3.15±0.97 mmol/L, P=0.033), cf-PWV (8.7±2.7 vs. 9.8±3.0 m/s, P<0.001) and ba-PWV (1 647.7±610.1 vs. 1 797.2±729.7 cm/s, P<0.001). ConclusionsThe degree of arteriosclerosis of patients who meet AHA standards is between that who meet the standard criteria and the normal population. For these patients, blood pressure should be actively controlled to delay the progression of arteriosclerosis.
ObjectiveTo investigate the effectiveness of free transverse gracilis myocutaneous flap for soft tissue defects of foot and ankle. Methods Between January 2017 and December 2020, 16 cases (17 feet) of soft tissue defects of foot and ankle were repaired with free transverse gracilis myocutaneous flaps. There were 10 males and 6 females, with an average age of 38 years (range, 23-60 years). There were 9 cases of left foot, 6 cases of right foot, and 1 case of bilateral feet. The causes of soft tissue defect were traffic accident injury in 3 cases, heavy object smash injury in 4 cases, machine injury in 3 cases, infection in 4 cases, electrical burn in 1 case, and synovial sarcoma after operation in 1 case. The wounds located at the distal plantar in 2 cases (2 feet), the heel and ankle in 6 cases (6 feet), the dorsum of the foot in 7 cases (8 feet), and the first metatarsophalangeal joint to the medial malleolus in 1 case (1 foot). The size of wounds ranged from 6 cm×5 cm to 18 cm×7 cm. The size of flap ranged from 11 cm×6 cm to 21 cm×9 cm. The donor site was sutured directly. Results After operation, 1 case (1 foot) of flap vascular crisis, 1 case (1 foot) of partial necrosis of the flap, and 1 case of partial dehiscence of the incision at donor site occurred, all of which healed after symptomatic treatment. The other flaps survived, and the incisions at donor and recipient sites healed by first intention. All patients were followed up 12-36 months (mean, 24 months). Except for 1 case (1 foot) of swollen flap, which underwent two-stage trimming, the other flaps had good shape and texture. All the flaps had a protective feeling. At last follow-up, Kofoed scores of foot and ankle function ranged from 73 to 98 (mean, 89.7); 13 cases were excellent, 2 cases were good, and 1 case was poor, with an excellent and good rate of 93.8%. Linear scar was formed at the donor site without adverse effect on lower limb function. ConclusionThe free transverse gracilis myocutaneous flap is an effective flap for repairing large soft tissue defects of foot and ankle due to its advantages of large excisable area, less variation of vascular anatomy, and concealment of donor site.
ObjectiveTo investigate the effectiveness of arthroscopic talocalcaneal coalition resection in painful adults via a modified posterior approach.MethodsBetween January 2015 and December 2017, 9 patients with painful talocalcaneal coalition accepted arthroscopic resection via the posterior malleolus high lateral observation approach combined with the lower medial operation approach. Of them, 6 were male and 3 were female, aged from 19 to 30 years (mean, 24 years). Among them, 2 cases had no definite local trauma and 7 cases had a history of sprain of foot and ankle. The disease duration ranged from 6 to 30 months, with a median of 12 months. Rozansky classification of talocalcaneal coalition for the 9 patients: 5 cases (5 feet) were type Ⅰ, 2 cases (2 feet) type Ⅱ, and 2 cases (2 feet) type Ⅲ. The patients had no sequelae of limb dysfunction and no limb joint surgery in the past. All the patients received anteroposterior and lateral X-ray films and CT scans of the ankle joint during follow-up. The visual analogue scale (VAS) score and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score were used to evaluate the effectiveness.ResultsThe operation time was 60-90 minutes (mean, 76 minutes). All patients were followed up 12-24 months (mean, 18 months). All the incisions healed by first intention, without infection, skin necrosis, lower extremity deep vein thrombosis, vascular nerve and tendon injury, bone bridge recurrence, and other complications. The ankle function recovered well and the pain was relieved obviously after operation, and the patients returned to work at 3-5 months after operation, with an average of 3.9 months. At last follow-up, the VAS score was 0.7±0.5, which was significantly improved (t=20.239, P=0.000) when compared with preoperative score (4.2±0.5); the AOFAS ankle-hind foot score was 94±4, which was significantly improved (t=−27.424, P=0.000) when compared with preoperative score (62±2). According to AOFAS ankle-hindfoot scoring system, the results were excellent in 7 cases and good in 2 cases at last follow-up.ConclusionIt is more intuitive, more space, and more flexibility for operation via the modified posterior malleolus high lateral observation approach combined with the lower medial operation approach in talocalcaneal coalition. It is feasible to remove talocalcaneal coalition programmatically according to the specific anatomic signs during the operation.

Objective To analyse the cl inical outcomes of the Z-osteotomy of the distal fibula to correct widened mortice of the ankle after fracture. Methods Between September 2009 and February 2011, 5 patients (5 feet) with widened ankle mortice after fracture underwent Z-osteotomy. There were 4 males and 1 female, aged from 23 to 58 years (mean, 38 years). At 3 months after operation of internal fixation when function exercises were done, patients got pains. The interval between trauma and operation ranged from 5 to 36 months (mean, 13.2 months). Lateral pressure test showed positive in2 cases and negative in 3 cases. American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 50.2 ±17.3. Results Primary healing of incision was achieved in all cases. Five patients were followed up 9 to 24 months (mean, 15.6 months). Mild to moderate swelling of the affected limb and anterolateral skin numbness of the i psilateral dorsal foot occurred, and gradually improved. The cl inical exam and radiology showed bone union at 12-15 weeks (mean, 13.5 weeks). Postoperative range of motion of ankle had no significant improvement. AOFAS ankle-hindfoot scores were 76.8 ± 11.2 at 6 months after operation, and 85.4 ± 3.2 at last follow-up, showing significant differences when compared with preoperative score (P lt; 0.05). Conclusion Shortened fibula is the main cause of widened ankle mortice after fracture; Z-osteotomy can effectively reduce the width of the ankle mortice, increase the stabil ity of ankle joint, and decrease the complication rate.
Objective By comparing with traditional L-shaped plate, to explore the effectiveness of new Pilon plate in the treatment of type C Pilon fracture.Methods A clinical data of 57 patients with type C Pilon fractures who met the selection criteria between May 2018 and January 2020 was analyzed retrospectively. Thirty-two patients were treated with new Pilon plate (trial group) and 25 patients with traditional L-shaped plate (control group). There was no significant difference in gender, age, cause of injury, fracture side and type, the interval between injury and operation between the two groups (P>0.05). The operation time and complications of the two groups were recorded. X-ray films were taken after operation to assess the quality of fracture reduction according to the Burwell-Charnley classification and fracture healing. Ankle function was evaluated according to Johner-Wruhs scoring standard and American Orthopaedic Foot and Ankle Society (AOFAS) score.Results The operations of the two groups were completed successfully, and the operation time of the trial group was significantly shorter than that of the control group (t=–3.025, P=0.005). After operation, the incision necrosis occurred in 2 cases of the control group, and the incisions of other patients in both groups healed by first intention. All patients were followed up 8-16 months, with an average of 10.1 months. There was no significant difference in follow-up time between the two groups (t=0.433, P=0.667). X-ray films showed that the ankle reduction of the trial group was rated as excellent in 28 cases and good in 4 cases, with an excellent and good rate of 100%, while in the control group, the ankle reduction was rated as excellent in 15 cases, good in 5 cases, and fair in 5 cases, with an excellent and good rate of 80.0%. There was a significant difference in the excellent and good rate of fracture reduction between the two groups (Z=–2.565, P=0.010). The fracture healed in both groups, and the healing time was (16.59±3.78) weeks in the trial group and (17.80±3.81) weeks in the control group, and there was no significant difference between the two groups (t=–1.191, P=0.239). At last follow-up, according to Johner-Wruhs scoring standard, the ankle joint function in the trial group was evaluated as excellent in 25 cases and good in 7 cases, with an excellent and good rate of 100%; the AOFAS score was 90.9±4.5. In the control group, 16 cases were excellent, 5 cases were good, and 4 cases were fair, and the excellent and good rate was 84.0%; the AOFAS score was 85.2±10.0. The ankle function scores of the trial group was superior to that of the control group (P<0.05). During follow-up, except for 1 case of ankle traumatic arthritis in the control group, there was no complication such as ankle malunion, plate loosening and fracture, or fracture reduction loss in both groups.Conclusion Compared with the traditional L-shaped plate, the new Pilon plate in the treatment of type C Pilon fracture has the advantages of high reduction quality, reliable fixation, less irritation to soft tissue, high fracture healing rate, and satisfactory functional recovery of ankle joint.
ObjectiveTo investigate the clinical application of the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap in repair of foot and ankle defects.MethodsBetween October 2014 and October 2018, 18 cases with foot and ankle defects were treated. There were 12 males and 6 females with an average age of 32.8 years (range, 8-56 years). There were 11 cases of traffic accident injuries, 3 cases of falling from height injuries, and 4 cases of heavy objects injuries. The wound was at the dorsum of the foot in 9 cases, the heel in 4 cases, the lateral malleolus in 5 cases. The time from injury to flap repair was 7-34 days (mean, 19 days). The size of wound ranged from 6.0 cm×2.5 cm to 11.0 cm×6.0 cm. The foot and ankle defects were repaired with the peroneal artery terminal perforator propeller flap in size of 6 cm×3 cm-18 cm×7 cm, which donor site was repaired with the anterior tibial artery perforator propeller flap in size of 8 cm×3 cm-16 cm×6 cm.ResultsOne patient had a hemorrhagic swelling in the peroneal artery terminal perforator propeller flap, and survived after symptomatic treatment. All recipient and donor sites healed by first intention. Eighteen patients were followed up 6-15 months (mean, 12.5 months). At last follow-up, the shape, color, texture, and thickness of the flaps in the donor sites were similar with those in the recipient sites. There were only linear scars on the donor sites. The two-point discrimination of the peroneal artery terminal perforator propeller flap ranged from 10 to 12 mm (mean, 11 mm). According to American Orthopaedic Foot and Ankle Society (AOFAS) score criteria, the results were excellent in 15 cases and good in 3 cases, with an excellent and good rate of 100%.ConclusionThe foot and ankle defects can be repaired with the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap. The procedure is not sacrificing the main vessel and can avoid the skin grafting and obtain the good ankle function.
