Based on the anatomical studies, the authors had designed an operation for treating old dorsal subluxation of the inferior radio-ulnar joint.The periosteum was longitudinally incised at the dorsal side of the lower ulna. forming musculo-periosteal flap, and a periosteal flap, and a periosteal valves of pronator quadratus. They were subluxation, passing the flap from palmar to the dorsal side through thc subperiosteal tunnel at the lateral margin of the radius corresponding to the ulna. Then it was circled round the lower end on the ulna and sutured to the muscular flap and the tough interosseous membranes at the palmar side, being used to stabilize the recuperated dorsal subluxation of the inferior radio-ulnar joint. The result of its clinical use was satifying.
ObjectiveTo investigate the effectiveness of tibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft in the treatment of tibial bone defects.
MethodsBetween January 2007 and December 2013, 19 cases of traumatic tibia bone and soft tissue defects were treated. There were 14 males and 5 females, aged from 18 to 49 years (mean, 28 years). The tibial fracture site located at the middle tibia in 6 cases and at the distal tibia in 13 cases. According to Gustilo type, 4 cases were rated as type Ⅲ A, 14 cases as type Ⅲ B, and 1 case as type Ⅲ C (injury of anterior tibial artery). The length of bone defect ranged from 4.3 to 8.5 cm (mean, 6.3 cm). The soft tissue defects ranged from 8 cm×5 cm to 17 cm×9 cm. The time from injury to operation was 3 to 8 hours (mean, 4 hours). One-stage operation included debridement, external fixation, and vacuum sealing drainage. After formation of granulation tissue, the fresh wound was repaired with sural neurovascular flap or posterior tibial artery perforator flap. The flap size ranged from 10 cm×6 cm to 19 cm×11 cm. In two-stage operation, tibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft was used to repair tibial defect. The periosteal flap ranged from 6.5 cm×4.0 cm to 9.0 cm×5.0 cm; bone graft ranged from 4.5 to 9.0 cm in length. External fixation was changed to internal fixation.
ResultsAll flaps survived with soft texture, and no ulcer and infection occurred. All incisions healed by the first intention. All patients were followed up 18-40 months (mean, 22.5 months). All graft bone healed, with the healing time from 3 to 9 months (mean, 6.5 months). No complication of implant loosening or fracture was observed. No pain and abnormal activity in the affected leg occurred. All patients resumed weight-bearing and walking function. The length of the limb was recovered and difference value was 0.5-1.5 cm between normal and affected sides. The function of the knee and ankle joint was good without infection, malunion, and equinus. According to the Johner standard at last follow-up, the results were excellent in 15 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate of 94.7%.
ConclusionTibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft is an effective method to treat bone defect of the tibia.
ObjectiveTo assess the effectiveness of pedicled iliac periosteal flap graft for treatment of avascular necrosis of the femoral head (ANFH) after femoral neck fracture in adolescents.
MethodsBetween December 2006 and August 2011, 9 patients (9 hips) with ANFH after femoral neck fracture were treated with pedicled iliac periosteal flap graft. There were 6 males and 3 females with an average age of 14.7 years (range, 10-18 years). Fractures were caused by traffic accident injury (5 cases), falling injury from height (3 cases), and fall injury (1 case). The time from injury to internal fixation with Kirschner wires or cannulated screws was 3-16 days, and all fractures healed within 10 months after internal fixation. The interval between fracture fixation and ANFH was 10-42 months (mean, 24.4 months). According to Steinberg staging system, 1 hip was classified as stage Ⅲb, 2 hips as stage Ⅲc, 1 hip as stage IVa, 3 hips as stage IVb, and 2 hips as stage IVc. The Harris scores and Steinberg classification were compared between at pre- and post-operation to assess the outcomes clinically and radiologically.
ResultsAll incisions healed by first intention. No complications of infection, deep venous thrombosis of lower limb, and pain and numbness of donor site were observed during or after operation. All patients were followed up 38-76 months (mean, 52 months). Joint pain was relieved; no leg length discrepancy was observed; the walking gait was improved and range of motion of hips was increased. The Harris score was significantly increased from 62.8±3.6 at pre-operation to 92.7±9.9 at last follow-up, showing significant difference (t=-12.244, P=0.000). The hip function was excellent in 5 hips, good in 3 hips, and poor in 1 hip, and the excellent and good rate was 88.89%. Post-operative radiological assessment demonstrated that only 1 hip (stage Ⅲb) had further collapse of the femoral head, the other hips had no incidence of deterioration. The radiological success rate was 88.89% (8/9).
ConclusionThe pedicled iliac periosteal flap graft for ANFH after femoral neck fracture in adolescents can provide good osteogenesis and vascular reconstruction of the femoral head.
OBJECTIVE To investigate the therapeutical effect of treatment of ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum. METHODS From June 1983 to August 1997, 106 cases with ischemic necrosis of femoral head (II stage in 64 cases, III stage in 39 cases, IV stage in 3 cases) were treated by the transfer of vascular pedicled iliac periosteum with ascending branch of lateral femoral circumflex vessel or deep circumflex iliac vessel pedicle. RESULTS Followed up 2 years and 4 months to 16 years, there were excellent in 54 cases, better in 38 cases, moderate in 9 cases, poor in 5 cases, and 86.8% in excellent rate according to the criterion of the therapeutical effect on the repair and reconstruction of adult ischemic necrosis of femoral head. CONCLUSION Treating ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum has the advantage of constant pedicle, easily drawing materials and reliable therapeutical effect.
ObjectiveTo assess the long-term effectiveness of the transplantation of iliac bone flap pedicled with deep iliac circumflex vessels for treating avascular necrosis of femoral head (ANFH) at Ficat stage Ⅱ and Ⅲ.
MethodsThirty-two cases (43 hips) of ANFH underwent iliac bone flap transplantation pedicled with deep iliac circumflex vessels between October 2000 and February 2006, and the clinical data were retrospectively reviewed. Of 32 cases, 27 were male (38 hips), and 5 were female (5 hips), aged 21-52 years (mean, 36.6 years); there were 8 cases (11 hips) of hormone ANFH, 18 cases (23 hips) of alcoholic ANFH, and 6 cases (9 hips) of idiopathic ANFH. The disease duration ranged from 2-52 months (mean, 8.2 months). According to Ficat staging criteria, 26 hips were classified as stage Ⅱ and 17 hips as stage Ⅲ. The preoperative Harris hip score (HSS) was 68.2±8.4. The HHS scores and X-ray photograph were compared between at pre-and post-operation to assess the outcomes clinically and radiologically.
ResultsAll incisions healed by first intention. Two cases had numbness of the lateral femoral skin. Four patients (6 hips) failed to be followed up, and the other 28 cases were followed up 98-187 months (mean, 129.3 months). Five patients (6 hips) showed aggravation or no relief with progression to stage Ⅳ at 8-69 months, who received total hip arthroplasty. The 10-year survival rate was 83.78% (31/37). The HHS score was significantly increased to 86.7±9.0 at last follow-up (t=-48.313, P=0.000). The hip function was excellent in 9 hips, good in 13 hips, and fair in 9 hips, and the success rate was 75.68%. Radiographic examination showed signs of bone remodeling at 6-8 weeks. After bone healing, the femoral head density gradually became uniform. Until last follow-up, ANFH progressed from Ficat stage Ⅱ to Ⅲ in 5 hips, from Ficat stage Ⅱ to Ⅳ in 3 hips, and from Ficat stage Ⅲ to Ⅳ in 3 hips; complete hip shape, continuous Shenton line, and normal joint space were observed in the other 26 hips, and the radiographic success rate was 70.27% (26/37).
ConclusionThe pedicled iliac bone flap transplantation for ANFH at Ficat stage Ⅱ and Ⅲ can provide good osteogenesis and vascular reconstruction of the femoral head. The long-term follow-up effectiveness is satisfactory.
Objective To estimate clinical effect ofspin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middleaged. Methods From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap wasstripped off, and transferred to the front of femoral neck fundus，then transplanted to the narrow inside of fracture through outer open door of articular capsule.Results All patients were followed up for 17 years. All fracture healedwithout femoral head necrosis, but mild arthritis appeared in 7 cases.Conclusion Vascular pedicled periosteum flap transfer of young and middle-aged femoral neck fracture, by decompression of femoral neck and reconstruction of blood circulation, can promote the fracture healing and decrease the wound and blood circulation destroy.
Objective To investigate the method and the curative effect of postauricular muscular fasciae-periosteal flap and modified unwrinkle incision in parotidectomy. Methods From January 2006 to August 2008, 28 patients with benign lesions of parotid gland were treated. There were 17 males and 11 females aged 19 to 79 years old (average 50 years old),including 20 cases of mixed tumor, 5 cases of adenolymphoma, 1 case of branchial cleft cyst, 1 case of eosinophil ic hyperplastic lymphogranuloma, and 1 case of myoepithel ioma. Tumor masses were all prominent, with the diameter of 2.4-3.8 cm and partial-tough texture. The course of disease was 3-18 months (average 9.5 months). Parotid gland and tumor mass were resected with postauricular incision hidden within the hairl ine, introcession defect (3.0 cm × 2.0 cm × 1.0 cm-3.5 cm × 2.5 cm × 1.5 cm) were repaired with simultaneouly adopting postauricular muscular fasciae-periosteal flap (4.0 cm × 3.0 cm × 1.0 cm-5.0 cm × 4.0 cm × 1.5 cm) by turning the pedicle flap 180°. Results All incision healed by first intention and no necrosis of postauricular muscular fasciae-periosteal flap occurred. All patients were followed up for 6-24 months (average 12 months). The incision was hidden within postauricular hairl ine and shape of parotid realm was good. No sal ivary fistula, facial paralysis, and earlobe numbness occurred. No Frey syndrome were found by local iodine-starch tests. Conclusion Because of hidden incision, good repair effect of region introcession deformity, and fewer postoperative compl ications, the modified parotidectomy with postauricular muscular fasciae-periosteal flap and modified unwrinkle incision is a better method in parotidectomy.
