Anomalous V-shape Palmaris Longus Tendon: Two Cases

Ali A. Alshaham, Paw Mular, Kadhim Jawad


We describe an incidental rare finding of V-shape tendon of Palmaris Longus (PL) in two cases. Examination of 253 subjects/506 hands for detection of PL Tendon by the standard clinical tests was undergone. The sample mean age was 21 years and M/F ratio was 1:3.The identification of V-shape bifid tendon was revealed only by Schaeffers test whiles both Thompsons and Mishras tests failed to demonstrate the anomaly. These two cases with anomalous tendon did not provoke any symptom. The importance of this finding being a potential source of V-shape support that can be used as tendon transfer to extensor tendons, in restoration procedure of radial palsy, and as free transplant in reanimation of oral and lid angles in facial palsy or any where when a V-shape support is required. Therefore surgeon awareness of this anomalous tendon and pre-operative identification is warranted.
