BACKGROUND: Rupture of the Achilles tendon is usually managed by surgical intervention. Recurrent tendon ruptures, segmental tendon defects, and overlying soft tissue defects render reconstructive procedures challenging. In this report, we present double or triple folding technique of the anterolateral thigh (ALT) free flap, and report the clinical outcomes of the reconstruction of combined defects, including the Achilles tendon and overlying soft tissue. METHOD: From 2008 to 2013, 7 patients un

BACKGROUND: Hip fractures are associated with notable mortality rates in elderly patients. The purpose of the study was to evaluate the mortality rate and influencing factors associated with mortality in the elderly patients with hip fractures. METHODS: Between October 2000 and December 2009, 807 elderly patients with hip fractures were enrolled in this study. There were 197 men and 610 women. The mean age at injuries were 78 years (range, 65-99 years). The fractures consisted of 390 femoral nec

Early reconstruction of severe open fractures, performed within 7 days of the injury, has a better outcome than closure after 7 days. However, the uncertain demarcation of damaged tissue often results in delayed reconstruction. In this article, we report our surgical outcomes of delayed reconstruction using latissimus dorsi free flap with internal fixation. Twenty-three patients with Gustilo type IIIB open tibial fractures Between March 2009 and May 2012 were included in this study. There were 1

The factors affecting the outcomes of segmental femoral shaft fractures are currently unknown. We evaluated the outcomes of intramedullary (IM) nail fixation and investigated factors affecting nonunion of femoral shaft segmental fractures. A total of 38 patients who underwent IM nail fixation for femoral shaft segmental fractures (AO/OTA 32C2) at three university hospitals with a minimum 1-year follow-up period were retrospectively reviewed. The patients were divided into union (n = 32) and nonu

We investigated the incidence of soft-tissue lesions after small head metal-on-metal total hip replacement (MoM THR). Between December 1993 and May 1999, 149 patients (195 hips) underwent primary cementless MoM THR. During the follow-up period, three patients (five THRs) died and eight patients (14 THRs) were lost to follow-up. We requested that all patients undergo CT evaluation. After exclusion of five patients (six THRs) who had undergone a revision procedure, and 22 (28 THRs) who were unwill

The thoracodorsal artery perforator flap is a versatile flap for the reconstruction of various soft tissue defects. Several anatomical variations of thoracodorsal artery have been described and an "accessory thoracodorsal artery" which has a separate and direct origin from the axillary artery has been reported. In this report, we describe a very unusual direct cutaneous perforator, which ran in a subfascial course above the latissimus dorsi muscle and was found to originate directly from the axi

The purpose of this study was to investigate the incidence of symptomatic venous thromboembolism (VTE) after chemoprophylaxis in patients with pelvic and lower-extremity fractures, and to identify risk factors for VTEs in this subgroup of patients. To detect VTE, multi-detector computed tomography (CT) angiography was performed. Of 363 patients assessed, the incidence of symptomatic VTE was 12.4% (45 patients), and the incidence of symptomatic PE was 5.2% (19 patients). For the risk-factor analy
