The effect of ethanol intake on tendon healing: a histological and biomechanical study in a rat model

Introduction  

Ethanol has a suppressive effect on inflammation and the immune system, but the effect of ethanol on tendon healing in vivo has not been studied. The purpose of this study was to investigate the histological and biomechanical effects of ethanol intake on tendon healing in a rat tendon injury model.     

髋臼骨折合并同侧下肢骨折临床治疗分析

目的：探讨髋臼骨折合并同侧下肢骨折的创伤机制和治疗方法。方法：髋臼骨折并同侧下肢骨折14例,男9例,女5例;年龄18～65岁,平均35岁。髋臼骨折按Letournel分型,后壁伴后柱骨折11例,单纯后柱骨折3例,均行钢板内固定。伴同侧股骨转子间骨折3例,1例行起重机架外固定,2例行DHS固定;伴同侧股骨颈骨折3例,均行空心钉加压固定;伴同侧股骨干骨折6例,1例行钢板固定,余5例行带锁髓内钉固定;伴同侧胫骨平台骨折2例,行钢板内固定。结果：1例半年后死亡,余13例获得随访,随访时间18个月～5年,平均30个月。按照美国矫形外科研究院髋关节疗效评定标准,优9例,良3例,差1例。结论：髋臼骨折合并同侧下肢骨折受伤暴力大、机制复杂、合并创伤多、易漏诊,应早期明确诊断,合理内固定。     

Oblong cup in the management of aseptic loosening of the acetabular component in total hip replacement.

BACKGROUND AND AIMS: At present, revision surgery of a total hip replacement is a major problem that must be dealt with by all orthopedic facilities. Aseptic loosening of the acetabular component is often associated with destruction of the original spherical shape of the acetabulum and the formation of bone defects. An orthopedist faces the challenge of acetabular revision and stable fixation of the new acetabular component in an effort to re-establish the functioning of the hip replacement. MATERIAL AND METHODS: The authors evaluated a group of 74 patients in whom they implanted an oblong revision cup due to aseptic loosening of the acetabular component from August 2000 until December 2003. The mean duration of the follow-up period was 63 months (ranging from 38 to 78 months). RESULTS AND CONCLUSIONS: The authors reported very good results from the use of this implant, where osteointegration and good functional outcome evaluated according to the Harris Hip Score (HHS) were achieved in 95% of cases. The long-term outcome should be the subject of further investigation.     

Reconstruction of the anterior column of the thoracic and lumbar spine with a carbon fiber stackable cage system.

A carbon fiber stackable cage system is presented to promote the reconstruction of the anterior column after vertebrectomy or corpectomy in tumor and trauma surgery. Modularity, immediate stability, early fusion of the graft, radiolucency, and no risk of disease transmission are the main advantages of this system.
