骨骼肌的縫合與癒合

本實驗以白兔的脛前肌為樣本，分離出整條肌肉、神經血管，並且避免傷到神經血管，在固定長度即近端66.7%位置，以刀切斷脛前肌，用不同的三種縫合方式來縫合方式來縫合，探討其癒合情況及癒合結果。在生理學上探討有關肌肉收縮力量，肌肉收縮長度，以及在組織學上，以H&E及ATPase染色，觀察肌肉受傷的癒合是否因為縫合方法不同，而結果不同。另在手術後，將實驗動物分成參組，第一組採自由活動，術後讓兔子自由活動，觀察肌肉傷口在正常活動狀況下癒合的情況，第二組固定一週，第三組是以石膏固定四週讓肌肉傷口在靜止狀況下癒合，藉此比較大抓力（suture-holding capacity），即Modified Kessler方式縫合而且術後不用固定。

This study used m.anterior tibialis of rabbits to document recovery after laceration and repair after a healing period of 12 weeks. Postoperation care were divided into three groups: cast immobilization one or four weeks, and free activity. There were three different methods used to repair muscles including simple suture with Dexon 2-0, modified Kessler with 1/4 width of mersiline 5-0 and simple suture with tendon graft. Physiologic recovery including tension force and muscle contracture length had been tested. Histologic recovery including H&E and ATPase had been examined. The recovery of tension force was influenced by immobilization time, not by suture method. The best recovery of tension force was resulted from postoperation care with free activity. The result of shortening length of muscle was according to different suture methods and had no relation with immobilization time. Modified Kessler suture resulted in the best muscle contracture length. The method of modified Kessler suture without immobilization was recommended for management of lacerated muscle.
