There is no objective data in the literature to support the statement that shoulder-girdle strength can be preserved better after muscle-sparing thoracotomy compared with standard thoracotomy. The aim of this study is to determine the decrease on muscle strength with objective criteria by measuring the peak torque value produced by the shoulder girdle.
Peak torque values on abduction and adduction of entire shoulder range at the velocity of 60 and 120 degree per second were measured with an isokinetik dynomometer which was attached to a computer. The measurements were performed in 20 cases, all candidates for thoracotomy. Patients were randomised into 2 groups; muscle sparing thoracotomy was undertaken in group A, and standard thoracotomy in group B. The same measurements were repeated 3 months after the surgery.
The decrease in postoperative PT values between group A and B was statistically significant (p<0.003). The decrease on shoulder abduction and adduction was insignificant in group A (p = 0.33 and p=0.13) and statistically significant in group B (p<0.0001 and p<0.001).
These results confirm the statement that shoulder girdle strength is better preserved with muscle-sparing thoracotomy.
文献中没有客观数据支持以下说法，即与标准开胸手术相比，保留肌肉的开胸手术后肩胛带力量能得到更好的保留。本研究的目的是通过测量肩胛带产生的峰值扭矩值，以客观标准确定肌肉力量的下降情况。
使用连接到计算机的等速测力计测量在每秒60度和120度速度下整个肩部外展和内收时的峰值扭矩值。对20例所有开胸手术候选患者进行测量。患者被随机分为两组；A组进行保留肌肉的开胸手术，B组进行标准开胸手术。术后3个月重复相同测量。
A组和B组术后PT值的下降具有统计学意义（p<0.003）。A组肩部外展和内收的下降不显著（p = 0.33和p = 0.13），而B组具有统计学意义（p<0.0001和p<0.001）。
这些结果证实了保留肌肉的开胸手术能更好地保留肩胛带力量这一说法。
