The value of magnetic resonance imaging and ultrasound in diagnosing displaced rupture of the thumb ulnar collateral ligament

Management of Complex Hand and Wrist Ligament Injuries

Ligamentous injuries in the hand and wrist are often underdiagnosed and can present with significant functional limitations if there is untimely recognition of injury. Adequate repair or reconstruction is critical in restoring joint stability and mobility. The purpose of this review is to provide an overview of the metacarpophalangeal joint, scapholunate interosseous ligament (SLIL), and non-SLIL carpal ligament anatomy, diagnosis, imaging, treatment consideration and options, as well as surgical techniques encompassing repair, reconstruction, and fusion.

Morphometry of thenar muscles by water bath ultrasonography in trapeziometacarpal osteoarthritis: intra- and inter-rater reliability

We studied the intra- and inter-rater reliability of muscle thickness and cross-sectional area measurements of thenar muscles with a water bath ultrasonography technique in eight healthy volunteers and 16 patients with trapeziometacarpal osteoarthritis. Thickness and cross-sectional area of the opponens pollicis, abductor pollicis brevis, flexor pollicis brevis, first dorsal interosseous and adductor pollicis muscle were measured. The results showed changes in the morphometric properties of the thenar muscles in patients with trapeziometacarpal osteoarthritis (TMC OA) compared with the healthy volunteers. In the dominant-sided patients (n = 14), there were lower cross-sectional area values for the abductor pollicis brevis and opponens pollicis muscles. In the non-dominant-sided patients (n = 10), there were lower cross-sectional area values for the abductor pollicis brevis and flexor pollicis brevis and lower muscle thickness of the abductor pollicis brevis. The water bath ultrasonography technique could be used to diagnose and treat diseases where changes in thenar muscle thickness and cross-sectional area can be expected.Level of evidence: III.
