A study of shoulder function was carried out in a group of 19 male patients who had their latissimus dorsi muscle removed as a free flap. A control group was examined to obtain data for the normal range of movement and power at the shoulder. Only a few patients had any subjective impairment of shoulder function; 13 of our 19 patients had a complete range of movement at the shoulder. There was no significant difference in power between the patient group and the control group when dominant and non-dominant sides were considered separately (p greater than 0.05). Patients who had surgery carried out more recently and patients with a scar contracture had a significantly higher disability score. The latter group also had a greater deficit in range of movement at the shoulder (p less than 0.05). Most patients encountered no difficulty whatever with their occupational and sporting activities. Our results support the view that the latissimus dorsi muscle is totally expendable and that there is no significant functional loss at the shoulder, either in casual or in forceful activities.
对一组19名男性患者进行了肩部功能研究，这些患者的背阔肌被作为游离皮瓣切除。检查了一个对照组，以获取肩部正常活动范围和力量的数据。只有少数患者有肩部功能的主观损害；我们的19名患者中有13名肩部活动范围完整。分别考虑优势侧和非优势侧时，患者组和对照组之间的力量没有显著差异（p大于0.05）。近期接受手术的患者和有瘢痕挛缩的患者残疾评分显著更高。后一组患者肩部活动范围的 deficit也更大（p小于0.05）。大多数患者在职业和体育活动中没有遇到任何困难。我们的结果支持这样的观点，即背阔肌是完全可牺牲的，并且在肩部无论是日常活动还是强力活动中都没有明显的功能丧失。 （注：原文中“deficit”未翻译完整，可能影响理解，建议补充完整准确含义。）
