The management of scapho-lunate (SL) instability remains controversial. Since 2001, the senior author has used a modified Brunelli tenodesis to achieve soft tissue stabilization in patients presenting with dynamic or static SL instability.

From 2001 to 2009, 13 patients were prospectively studied. All patients complained of painful clicking in the wrist, inability to use the wrist for loading activities, and all had a positive scaphoid shift test (Kirk Watson). Wrist arthroscopy was performed to confirm the diagnosis and to confirm the absence of degenerative change in all cases. Data collection pre-operatively included, range of motion, grip strength, DASH score and pain score.

All patients had wrist immobilisation in a forearm cast for six weeks post operatively. Physiotherapy commenced at that stage and clinical assessment was performed at 3 months, six months and 12 months post surgery. Patients were discharged from follow-up after 12 months.

A significant improvement in grip strength and DASH score was documented at the 12 month post operative assessment. The range of wrist flexion was decreased in all patients. The majority returned to their original employment. All patients reported that their wrist instability symptoms were improved.

Conclusion

Scapho-lunate ligament reconstruction using a split flexor carpi radialis tendon graft to achieve soft tissue stabilization, provided satisfactory results in patients with chronic SL instability. Improvement in DASH score and grip strength were documented at one year follow-up.
