摘要
目的:对创伤性近侧指间关节挛缩的发病机制和治疗方法进行探讨。方法:对1995～2000年在我院治疗的创伤性近侧指间关节屈曲挛缩病例进行回顾,指间关节挛缩的发病机制,根据关节内外粘连的不同因素进行松解手术治疗。结果:创伤性近侧指间关节屈曲挛缩的病变可分为关节内粘连、关节外粘连及复合性粘连。经过:(1)单纯松解掌板延长及屈指浅肌腱切断等手术。(2)手术加牵引术,取得了良好结果。平均改善关节活动度达100度(屈)(伸)-10度。结论:(1)创伤性近侧指间关节屈曲挛缩的发生与早期处理不当有关。(2)粘连可以是关节内或关节外因素及复合因素造成。(2)手术治疗配合术后牵引治疗可取得良好的效果。
Objective: To explore the mechanisms of occurrence and the treatment methods for the traumatic stiff promimal interphalangeal joint in flexion. Methods: 16 cases of the stiff pronimal interphalangeal joints in flexion treated operatively(from 1995 to 2000)was reviewed. The tendolysis had been performed on the hasis of different factors in or out the joint. The occur mechanisms of this disease had also heen analyzed. Results: The pathological changes of the traumatic stiff promimal interphalengel joint in flexion may divide into in or out joint adherence. The results of operation had been satisfying. 100°(flexion)= - 10°(extention) mobilizing degree was obtained in all 23 fingers enrolled. Conclusion:(1)The stiff promimal interphalangeal joint in flexion are related to improper early treatment. (2)The adherence or comtracture might be caused by in or out joint factors. (3)Operation followed by proper traction treatment could obtain ideal result.
