A 38-year-old man sustained a traffic accident injury to his right medial malleolus and leg. It was an open fracture of the right tibia and fibula accompanied by a large soft tissue defect of the right medial malleolus sized 12 cm multiply 4 cm. Doppler examination revealed that the tibialis posterior vessel was occluded due to thrombosis. The anterior tibial artery was patent. Three weeks after injury, the left anterolateral thigh muscle flap was harvested and transplanted to the right medial malleolus defect area for repair of the soft tissue defect, and an end-to-side anastomosis was performed between the posterior tibial vessel of the contralateral leg and the muscle flap's vascular pedicle. A split thickness free skin graft was used to cover the muscle flap and around the flap's vascular pedicle. The vascular pedicle was cut off after 28 days and the muscle flap survived completely. After 3-year follow-up postoperatively, the right tibia and fibula fractures were confirmed healing radiologically. The posterior tibial artery of contralateral leg was patent by clinical and Doppler examinations. This technique can be used to preserve the flow and patency of recipient arteries.

Both severed legs were replanted in a 41-year-old man. Bilateral tibia and fibula were shortened by 4 cm equally. Tibial fixation was performed with reconstruction plate. Four weeks after the replantation, active and passive exercises were initiated in both of the knee joints. Four months after surgery, the patient was capable of walking independently for 20-30 m without the aid of crutches. After 28 months' follow-up, plantar sensitivity was defined as S3. This patient was satisfactory with the cosmetic and functional results.

This paper discussed the injury mechanism and management of a patient who had concomitant ipsilateral hip and knee dislocations and contralateral open leg fracture. A 32-year-old man presented with ipsilateral fracture-dislocations of the left hip (Pipkin's type IV) and knee (Moore II) joints and contralateral open fracture of the leg bones after a car accident. After emergency resuscitative measures, the hip joint was reduced and Pipkin's fracture was fixed using Ganz approach with lag screws; knee joint was reduced closely and tibial plateau fracture was stabilized with lateral buttress plate and a transarticular spanning fixator. The open fracture on the other leg was debrided and fixed with an external fixator. There was no instability in both joints after fixation when he was examined under anesthesia. The fractures united after 3 months and the patient had no residual instability of hip and knee. There was no clinical or radiological evidence of osteonecrosis in the hip joint after 6 months. At one-year follow-up, he had satisfactory functional outcome with almost normal range of motion at both joints. Ipsilateral hip and knee dislocations are rare injuries and more caution is needed for early diagnosis. A timely appropriate intervention can provide good functional outcome to the patient in this situation.

The treatment of an above knee amputee who has sustained a fracture of the femoral neck is a chal- lenging situation for both the orthopedic surgeon and the rehabilitation team. These fractures may be managed acutely either by reduction and internal fixation or by endoprosthetic replacement based on the same criteria as in any other patient with otherwise intact limbs.We present a neglected case treated successfully with valgus osteotomy. We conclude that these fractures should be treated with the same urgency and expertise as similar fractures in non-amputees as long-term survival and good quality of life can be expected.

A 68-year-old female patient was treated for unhealed ulcer in the fourth toe of the left foot. Clinical examinations identified severe stenosis of the proximal segment and occlusion of the distal segment of the left anterior tibial artery, and occlusion of the left posterior tibial artery and the peroneal artery. The proximal stenotic segment of the left anterior tibial artery was dilated, but the distal occlusive part failed to be re-canalized. Left anterior tibial artery to dorsal pedal artery bypass was performed on the patient with an epoxide-crosslinked, special radicals antigen-sealed, porcine-derived biological graft; debridement of the left 4th digiti pedis was also performed. Postoperation course was uneventful. The pulse of the left dorsal pedal artery was strong. The ankle brachial index (ABI) increased from 0.60 to 1.09. Warfarin and two antiplatelet drugs were given after the operation. Six months after operation, computed tomographic angiogram (CTA) identified the patent graft.

OBJECTIVETo evaluate a method to partially remove gastrocnemius for improvement of the contour of the leg.

METHODSThirteen patients with bulked calf were undergoing the treatment. With a self-designed apparatus, the gastrocnemius was partially removed by placing the device in the muscle through an incision in the popliteal fossa. The follow-ups were carried out for 1-6 months.

RESULTSThirteen patients were successfully treated by above mentioned technique. The removed amount of muscle was weighted between 11 g and 201 g, averaged 77 g. All of the patients could be able to walk three days after the operation. But, the normal walk had to take 1 month after of the surgery for recovering. The function of the ankle joint was not obviously influenced.

CONCLUSIONThe above mentioned technique is a safe and effective method for re-contouring the leg.

OBJECTIVETo evaluate the clinical application of the medial approach for repairing popliteal artery injuries.

METHODSFrom 2002 to 2008, 11 cases of popliteal artery injuries had been repaired via the medial approach. Of these cases, 8 had limb fractures, 1 had knee dislocation, and 2 had visceral injuries. Ten popliteal arteries were anastomosed directly while one was repaired with a great saphenous vein graft.

RESULTSThe operation time ranged from 3 to 4 hours (averaging 3.6 hours). All the injured limbs survived. At the follow up, 8 legs recovered the full function, 2 had minor contracture, and 1 serious Volkmann's contracture without amputation.

CONCLUSIONThe medial approach for repair of the popliteal artery is effective, applicable, and more advantageous to the management of multi-injures.

OBJECTIVE: To investigate the effect of different proximal femoral shapes on leg length discrepancy(LLD) after total hip arthroplasty(THA). METHODS: Total 131 patients with osteoarthritis or osteonecrosis received unilateral biological total hip arthroplasty from June 2013 to June 2019. All patients' age, sex, side and pelvis anteroposterior digital radiography were retraspectively analyzed. There were 69 males and 62 females, 57 cases of left hip and 74 cases of right hip. The age ranges from 25 to 89 with an average age of 62 years. There were 48 cases of osteoarthritis and 83 cases of osteonecrosis. In this study, femoral cortical index (FCI) was used as the classification of proximal femoral shape, and bilateral lower limb length differences were measured by preoperative and postoperative pelvis anteroposterior digital radiography. Grouping according to FCI:> 0.6 was Dorr A group, 0.5 to 0.6 was Dorr B group, <0.5 was the Dorr C group, and the relationship between proximal femur morphology and the leg length discrepancy after total hip arthroplasty was determined. RESULTS: The postoperative average FCI was(0.56±0.08) mm and the median LLD was 5.10 mm (IQR -1.00 to 8.80 mm). Three groups were divided according to the level of FCI, and there were no statistically significant differences in gender, age, side, diagnosis and intraoperative fracture rate distribution among three groups. FCI>0.6, the postoperative LLD was 6.30 mm (IQR 1.00 to 10.95 mm). When FCI was 0.5 to 0.6, the postoperative LLD was 5.85 mm(IQR-0.55 to 8.90 mm). FCI<0.5, the postoperative LLD was 1.95 mm(IQR -2.50 to 6.68 mm). LLD comparison of different proximal femoral shape was statistically significant ( CONCLUSION High FCI increases the risk of lower extremity prolongation after surgery on the affectedside, while low FCI reduces the risk of lower extremity prolongation after surgery on the affected side. The surgeon can assess the shape of the proximal femur of the patient preoperatively and inform the patient in advance of possible changes in leg length of both lower extremities after total hip replacement.
