桡侧腕短伸肌腱部分移位修复第一腕掌关节脱位的应用解剖与手术设计

Applied Anatomy and Operation Design of Transposition of Partial Tendon of Musculus Extensor Carpi Radialis Brevis to Repair Dislocation of Carpometacarpal Joint of thumb

目的:为桡侧腕短伸肌腱部分移位修复第一腕掌关节脱位提供解剖学依据。方法:30侧成人上肢标本,将桡侧腕短伸肌腱分为上、中、下3部分,进行形态学测量。结果:桡侧腕短伸肌腱长度为(15.3±1.9)cm(10～22.5cm),其宽度:上段为(15.4±5.2)mm(5.3～23.8mm),中段(10.0±3.0)mm(4.2～18.5mm),下段(5.5±0.6)mm(3.7～9.6mm);厚度:上段为(0.6±0.3)mm(0.1～1.4mm),中段为(1.8±0.7)mm(0.7～3.0mm),下段为(2.1±1.2)mm(0.8～3.1mm)。结论:桡侧腕短伸肌腱部分转位有足够的长度以修复第一腕掌关节脱位。

Objective：To provide anatomical basis for the operation of the transposition of partial tendon of musculus extensor carpi, radialis brevis to repair dislocation of carpometacarpal joint of thumb.Methods：To classify tendon of musculus extensor carpi radlalis brevis into three parts, morphology configuration were measured on 30 adult cadaver upper limbs. Results： The lenth of the tendon of musculus extensor carpi radlalis brevis is （15.3± 1.9）mm（ 10～ 22.5cm）. The width of tendon is （15.4 ± 5.2）mm （5.3±23.8mm）,（10.0± 3.0）mm（4.2±18.5mm） and （5.5±0.6）mm（3.7± 9.6mm） in the upper, middle and lower part. The thicknesses of the tendon is （0.6±0.3）mm（0.1± 1.4mm）,（1.8±0.7）mm（0.7±3.0mm） and （2.1 ± 1.2）mm（0.8±3.1 mm） in the upper part, middle part, lower part. Condusion：The transposition of tendon of musculus extensor carpi radialis brevis has enough lenth to repair dislocation carpometaearpal joint of thumb.
