Abstract

Localized medial triquetral-hamate instability (LTHMI) is a relatively uncommon form of wrist instability. After an initial traumatic lesion elongating the triquetral-hamate (TH) complex (TH medial ligament and floor of the extensor carpi ulnaris [ECR] sheath), pain occurs during professional activities demanding ulno-radial movements (polo, tennis, music playing). Imbrication of the TH complex and augmentation with the ECU tendon is suggested for LTHMI.
