Objective To investigate the effect of transplantation of the cutaneous iliac flap on repairing bone and soft tissue defect of metatarsal. Methods From October 1999 to December 2003, the cutaneous iliac flap was designed for the repair of bone and soft tissue defect of metatarsal in 4 male patients, whose ages ranged from 26 to 47, with skin graft for the coverage of the iliac flap. The duration of injury ranged from 1 to 5 months. The length of the defect ranged from 4 to 7 cm and the defect area ranged from 5 cm×3 cm to 9 cm×5 cm. Results One week after transplantation, complete survival of iliac flap was observed in 3 cases and partial survival in 1 case (but later proved survived). Callus was seen 1 month after transplantation and Kwires were removed 4months after transplantation. Patients were followed up for 5 to 24 months. There were no ulcers. The ability of walking and bearing was satisfying as well asthe function and shape. Conclusion With satisfying restoration of function and shape, transplantation of the cutaneous iliac flap with skin graft is an alternative to treat bone and soft tissue defect of metatarsal with one stage surgery.
Since 1979, vascularized iliac bone graft based on the deep circumflex iliac vessels (DCIV) or the deep superior branches of superior gluteal vassels (SGV) was used to the treatment of bone defect, non-union of fracture, and aseptic necrosis of the femoral head in Ⅱ4 cases. Of these Ⅱ4 graftings, 68 were pedicled, 46 were microvascular free transfer. Early callus formation developed 6 weeks after surgery. Solid bony union was obtained in 3 months. Among 32 patients with aseptic necrosis of femoral head followed more tha 1 years, dior relief of pain and omprovement of X-ray findings were obtained in 31. The advantages of using vascularized iliac bone graft, especially based on the DCIV and SGV, are discussed. The author has a good opinion of vascularized iliac bone graft based on the SGV.
From March. 1987 to March. 1989,we have treated 8cases of children with avascular necrosis of the femoral headby synovectomy of the hip and lateral circumflex femoralartery pedicled iliac bone graft to the femoral neck. Satisfac- tory therapeutic results were achived. The advantages of thisoperation are : 1. the microcirculation of the femoral headwas improved-by intraarticular decompression. 2. the venouspressure decreased by osteotomy at femoral head and neck.3. iliac bone graft can prevent femoral head coiiapsc.4.the blood supply of the femoral head was recstablished by vascularized iliac bone gredt.
In this experiment, bone grafts with or without perios-teum were taken from both ilium, usually a small amont ofmuscle was attached. These two types of grafts were trans-ferred respectively to the subcutaneous layer of the feet andto the defects of the metacarpus. After the operation , thespeciments were under gross and histologic examinations, andvolumetric measurment of the grafts pericdically. Vascularregeneration was found one week after operation, and thosegrafts with periosteum showed vascular regeneration and less absoption more than those with no periosteum. The vascular regeneration of the abundant iliac grafts transfered to the dcfects was more than to the subcutaneous layer.
Objective To evaluate the effectiveness of arthroscopic Pushlock anchor fixation with iliac creast bone autograft in the treatment of recurrent anterior shoulder instability with critical bone defect. Methods The clinical data of 80 patients with recurrent anterior shoulder instability with critical bone defect treated by arthroscopic Pushlock anchor fixation with iliac creast bone autograft between January 2016 and January 2019 were retrospectively analyzed. The patients were all male; they were 18-45 years old at the surgery, with an average of 25 years old. The disease duration ranged from 3 months to 5 years, with an average of 2 years. The shoulder joint dislocated 3-50 times, with an average of 8 times. X-ray films, MRI, CT scans and three-dimensional reconstruction of the shoulder were performed before operation. The area of the anterior glenoid defect was 25%-45%, with an average of 27.3%. The shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score were used to evaluate the shoulder function before operation and at last follow-up. ResultsPatients were followed up 1-3 years, with an average of 2 years. No shoulder dislocation occurred again during follow-up. All partial graft absorption occurred after operation, CT scan showed that the graft absorption ratio was less than 30% at 1 week and 3 months after operation. CT three-dimensional reconstruction at 1 year after operation showed that all grafts had healed to the glenoid. The anterior glenoid bone defect was less than 5% (from 0 to 5%, with an average of 3.2%). At last follow-up, the shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score significantly improved when compared with preoperative ones (P<0.05). The shoulder mobility of external rotation in abduction at 90° of the affected side limited when compared with the healthy side [(6.7±5.1)°]. ConclusionArthroscopic Pushlock anchor fixation with iliac creast bone autograft has a good effectiveness in the treatment of recurrent anterior shoulder instability with critical bone defect. The method is relatively simple and the learning curve is short.
The sternum is the pivotal component of the thoracic cavity. It is connected with the clavicle and ribs on the upper part and both sides respectively, and plays an important role in protecting the stability of the chest wall. Sternal resection usually results in a large segmental chest wall defect that causes the chest wall to float and requires sternal reconstruction. This paper reports a 62 years male patient with thymic squamous cell carcinoma with sternal metastasis, who underwent thymotomy, sternal tumor resection and autologous lilum graft combined with sternal reconstruction by titanium plate after relevant examination was completed and surgical contraindications were eliminated. The patient was followed up for 6 months, the respiratory and motor functions were normal and the thoracic appearance was good.
