INTRODUCTION
The Palmaris longus, one of the most variable muscles in the body both flexes the wrist and tenses the palmar fascia. It is used by surgeons as a source of tendon graft and racial differences in its variation have been documented. We sought to determine the frequency of the absence of the Palmaris longus in an East African population.
METHODS
A prospective study was conducted using ten common clinical tests among patients and students in a large teaching hospital in East Africa to determine the presence of a Palmaris longus.
RESULTS
The overall rate of absence was 4.4% with unilateral absence at 3.3% and bilateral absence at 1.1%. The overall difference between males and females was not statistically significant (p = 0.605). Participants were more likely to have absence in their non dominant hand.
DISCUSSION
Our findings though in contrast to many studies worldwide, it concurs with most studies done in the African setting. These differences may be due to the higher levels of manual labour and the more use of the right hand in these activities. The frequency of the absence of Palmaris longus in East Africa has been determined. Surgeons should acquaint themselves with prevalence in their areas of practice.
引言
作为腕部屈肌和掌侧筋膜的紧张肌，掌长肌是人体变化最多的肌肉之一。外科医生常将其作为肌腱移植物的来源，其变化的种族差异已有相关记录。我们旨在确定东非人群中掌长肌缺失的发生率。
方法
在东非的一家大型教学医院，对患者和学生进行了一项前瞻性研究，使用了十种常见的临床测试来确定掌长肌的存在。
结果
总体缺失率为 4.4%，单侧缺失率为 3.3%，双侧缺失率为 1.1%。男性和女性之间的总体差异无统计学意义（p=0.605）。参与者在非优势手上更有可能出现缺失。
讨论
我们的研究结果与世界范围内的许多研究结果相反，但与非洲的大多数研究结果一致。这些差异可能是由于在这些活动中，较高的体力劳动水平和更多地使用右手所致。已经确定了东非掌长肌缺失的频率。外科医生应了解自己在实践区域的流行情况。
