The palmaris longus muscle (PLM) is extremely variable both in number and form. We present the first reported case of three-headed reversed PLM in a 36-year old woman. The relevant literature is reviewed. Variations of the muscles of the forearm and specifically the PLM are not uncommon. However, different rates are given for the types and agenesis of PLM. In one study, the incidence of agenesis was 12.8% and other anomalies were 9%. 15 cases of reversed PLM have been reported in the literature. In our case, the three-headed PLM was resected. The patient's symptoms resolved and at 1-year follow-up she remains symptom-free.
掌长肌（PLM）在数量和形态上极具变异性。我们报告首例36岁女性三头反转掌长肌病例，并对相关文献进行综述。前臂肌肉尤其是掌长肌的变异并不罕见。然而，掌长肌的类型和发育不全发生率有不同报道。一项研究中，发育不全的发生率为12.8%，其他异常为9%。文献中已报道15例反转掌长肌病例。在我们的病例中，切除了三头掌长肌。患者症状缓解，随访1年无症状。
