  • Title: Using Extensor Retinaculum to Reconstruct the Thumb Metacarpophalangeal Joint Ulnar Collateral Ligament.
    Author: Mastella D, Gorski J, Ashmead D, Wollstein R.
    Journal: Tech Hand Up Extrem Surg; 2020 Nov 06; 25(3):165-168. PubMed ID: 33165166.
    Abstract:
    Chronic complete tears of the ulnar collateral ligament of the thumb metacarpophalangeal joint often require surgical reconstruction. The indications, materials used, and the methods for reconstruction remain controversial. We describe a technique for reconstruction that utilizes a slip of the extensor retinaculum for reconstruction. The advantages of extensor retinaculum as a graft choice are that it matches the native ligament with a synovial and nonsynovial surface, has elasticity similar to the ligament and minimal donor site morbidity. Reconstruction of the ulnar collateral ligament with this graft successfully restores pinch.
