First extensor tendon compartment is composed of Extensor pollicis brevis (EPB) and Abductor pollicis longus (APL) and lack of knowledge of anatomical variation in conventional textbooks regarding these tendons lead to misdiagnosis of underlying condition.In our case, similar sized tendon slips of EPB with synovial sheath thickening was reported in Ultrasound (USG) as intra-substance tear and thus the inaccurate surgical plan was decided delaying the treatment and patient’s loss from work. Exploration of tendons lead to the findings of accessory slip of EPB and just pulley release of the same lead to faster restoration of daily activities without pain thus combating the surgical expense in resource deprived patient.
