Abstract

The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Extensor tendon injuries are common and they can lead decreased wrist and finger movements. Classification of extensor injuries into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate management. In our retrospective observational study, we analyzed the demographic data, management & surgical outcomes of primary repair in 78 patients who presented with extensor tendon injuries in zone 6, according to Verdan’s classification, to our institute from May 2021 to April 2022. 71 (91.02%) patients were males and 7 (8.98%) were female patients. The average age of patients were 34.6 years. Right hand was involved more than the left The most common etiology was work spot injury, mostly cutting machine injuries which accounted for 35 patients. The next most common cause was glass cut injuries seen in 23 patients. 15 patients had associated bony injuries. 55 patients had injury to multiple extensor tendons and 23 patients had injury to single extensor tendon. A total of 168 tendons were repaired. Functional outcomes were studied using Miller’s criteria. The outcomes of the zone 6 extensor repair depends mainly on the severity of the tendon injury, injury to adjacent structures, strength of the repair and patient’s compliance to physiotherapy
