Recently, palmaris longus has been introduced   as an independent risk factor for the development of carpal tunnel syndrome. The   purpose of this study was to assess the association of carpal tunnel syndrome with   the presence of palmaris longus tendon and functional superficial flexor of the fifth   finger.   Methods: Fifty-four patients with severe and bilateral carpal tunnel syndromes   that had indications for carpal tunnel release, and underwent surgery, were enrolled   prospectively in this study. Seventy patients as control group were selected on a basis   of age, gender, occupation, diabetes mellitus, thyroid disease, and rheumatoid   arthritis. The presence or absence of the palmaris longus tendon and functional superficial flexor tendon to the little finger were assessed in both groups clinically.   Results: The prevalence of palmaris longus agenesis was significantly lower in   the carpal tunnel group but there was no association between carpal tunnel syndrome   and presence of functional superficial flexor to the little finger.   Conclusion: The presence of the palmaris longus tendon is associated with the   development of carpal tunnel syndrome.   M3 ER -
