Flexor pollicis longus anomaly- Linburg-Comstock anomaly with tendon injury- a case report

We present a case of abnormal congenital communication between flexor pollicis longus(FPL) and flexor digitorum profundus(FDP) of index finger, which was found incidentally while exploring this case of Zone II flexor tendon injury of right thumb. FPL has many anatomical variations. Although many variations exist, abnormal tendinous communication between FPL and FDP is called LinburgComstock anomaly. Excision of this abnormal tendinous slip facilitated FPL repair.
