Collateral ligament reconstruction of the chronic thumb injury with bio-tenodesis screw fixation

Tech Hand Up Extrem Surg. 2014 Dec;18(4):160-4. doi: 10.1097/BTH.0000000000000058.


We describe a new technique for the reconstruction of chronic lesions of the collateral ligaments of the metacarpophalangeal ligaments of the thumb, using a Bio-Tenodesis screw for the fixation of a tendon graft in a triangular manner with proximal apex and allowing early mobilization, starting 2 weeks after operation. Short-term results after 12 to 43 months (mean, 26 mo), showed no significant differences in grip and pinch strength compared with the opposite thumb and restricted loss of motion in the metacarpophalangeal joints (10%) and the interphalangeal joints (4%). We conclude that this technique minimizes the rehabilitation and sick leave period and represents a good alternative to other methods.
