缝匠肌骨瓣移植空心拉力钉固定治疗青壮年股骨颈骨折

目的：通过采用缝匠骼骨瓣移植、空心拉力钉固定治疗青壮年股骨颈骨折,获得更好的疗效。方法：自１９９２年１月～１９９９年１２月,采用缝匠肌骨瓣移植桥接与空心拉力钉固定治疗青壮年股骨颈骨折,随访时间１～５年,平均４年。结果：７３例新鲜骨折中１例骨折不愈合,股骨头坏死,１例骨折愈合股骨头坏死;２７例移位型陈旧骨折中３例骨折不愈合,股骨头坏死,２例骨折愈合后股骨头坏死。骨折愈合率９６％,股骨头坏死率７％。结论：缝匠肌骨瓣移植可改善股骨头血供并使植骨以“活骨骨折愈合”的方式完成,陈旧性骨折股骨颈吸收的可重建股骨颈,井有一定的强度支撑防止股骨头坏死应力塌陷,与空心拉力钉有协同支撑固定作用。三根空心拉力钉固定创伤小而连接控制面积大是理想的内固定物。

Vacuum‐assisted closure therapy for vascular graft infection (Szilagyi grade III) in the groin—a 10‐year multi‐center experience

The aim of the study was to evaluate the benefit of vacuum‐assisted closure (VAC) therapy in the management of deep, alloplastic graft infections (Szilagyi grade III) in the groin. From 2000 to 2009, we identified and included in our study 72 deep inguinal infections in 68 patients, involving native as well as synthetic graft or patch material. There were 29 early graft infections (<30 days after implantation) and 43 late infections (≥30 days after implantation). Among these, 17 cases involved native grafts/patches (12 grafts and 5 patches), while 55 cases involved non‐native grafts/patches [26 polytetrafluorethylene (PTFE) grafts and 24 Dacron grafts (Haemashield, Meadox Medical, Boston Scientific Corporation, Natick, NY; Gelsoft graft, Vascutek, Inchinnan, Renfrewshire, Scotland, UK; Intervascular, Mahwah, NJ); INVISTA, and 5 Vascu‐Guard^? bovine pericardial patches; Synovis Surgical Innovation]. All patients were treated with multiple wound debridements, graft salvage, sartorius myoplasty, intravenous antibiotics and VAC therapy until thorough surface healing was achieved. Exclusion criteria were an alloplastic graft infection with proximal expansion above the inguinal ligament, blood culture positive for septicaemia or septic anastomotic herald or overt bleeding. Nine months after initiation of therapy, overall, graft/patch salvage was achieved in 61 of 72 (84·7%) cases. Of the native graft/patch group, infected graft material was replaced with an autogenous great saphenous vein graft or patch in four patients (23·5%). In the non‐native group, vein or synthetic graft preservation without revision was achieved in 48 of 55 (87·3%) patients. The mean duration of VAC therapy was 16 ± 7·7 days, and postoperative mean hospital stay was 25·3 ± 8·5 days. In 23 of 72 (31·9%) cases, a secondary closure of the wound was achieved; in the other 49 cases, wound healing was achieved by meshed split‐thickness skin grafting. Mean wound healing time for all wounds was 24·3 ± 12·5 days. Specific complications during VAC therapy were wound fluid retention in 2 cases and an increased need for analgesics in 12 cases (16·66%). Negative pressure wound therapy (NPWT) has been reported to be useful in the treatment of severe wound infections. Even in the presence of synthetic vascular graft material, NPWT can greatly simplify challenging wound‐healing problems leading to wound dehiscence and its sequelae. Our long‐term experience demonstrates the safety and effectiveness of VAC therapy in the management of deep graft infections.
