Scapholunate ligament reconstruction using a part of the extensor carpi radialis brevis tendon through a dorsal...

Thirty-six patients were assessed after scapholunate ligament reconstruction using a portion of the extensor carpi radialis brevis through a dorsal approach. The median age was 53 years. Most (27/38) were graded as scapholunate advanced collapse Grade I. At a median of 47 months after treatment, hand function using the Disabilities of Arm, Shoulder and Hand Questionnaire was 12. The postoperative range of wrist flexion and extension movement was 77% and grip strength 92% compared with the uninjured side. The median patient satisfaction was rated as 9/10. Median pain scores without and with load, using the numeric pain scale (0-10), were 1 and 3, respectively. This reconstruction leads to initial normalization of radiological features, such as scapholunate interval, scapholunate and radiolunate angles, but a notable loss of the immediate postoperative reduction was observed in long-term follow-up, which was not accompanied by any deterioration in the clinical examination. This technique, even in scapholunate advanced collapse type I wrists, resulted in long-term, improved outcomes compared with other techniques.Level of evidence: IV.
