Management
Injury to the extensor hood at the dorsal metacarpophalangeal joint leading to tendon instability may necessitate surgical intervention using a bone tunnel technique for graft placement, which creates a new pulley mechanism [PMID:20610064].
Complications
Chronic injuries often involve subluxation of the extensor tendon, indicating the progression of instability that may require surgical interventions such as local tissue grafting and pulley creation [PMID:20610064].
