Abstract
BACKGROUND
Kienbock's disease results in altered wrist biomechanics producing debilitating pain at the wrist. The disease is staged according to radiological and clinical findings and the stage guides the treatment. Various treatment options have been described for stage 3, however, there is a lack of consensus over these treatment methods. Scaphocapitate fusion is the preferred surgical option for advanced Kienbock's disease. Previous studies had heterogeneous cohorts with a short duration of follow-up and a lack of uniform surgical technique. The purpose of the study was to show the long-term functional and radiological outcome of scaphocapitate arthrodesis (SCA) by using Herbert screw for the treatment of Kienbock's disease in manual workers.
METHODS
For this single-centre, retrospective study, all consecutive patients who were manual workers and managed by SCA between January 2010 and Jan 2014 for Lichtman stage IIIA and IIIB with at least 7 years of follow-up were included. Patients were assessed using clinical and radiological parameters preoperatively and in the follow-up period. Disabilities of the Arm, Shoulder, and Hand (DASH), Patient-Related Wrist Evaluation (PRWE), and VAS for pain were assessed.
RESULTS
Out of 27 patients, 4 lost to follow-up, therefore, 23 patients (14 women and 9 men) with 30 years of median age at the time of the surgery were included. DASH scores, PRWE scores, and VAS for pain significantly improved (p < 0.5) after surgery. Wrist range of motion and grip strength also improved significantly (p < 0.5). Postoperative radiological parameters were found to be within a normal range.
CONCLUSION
Scaphocapitate fusion by Herbert screws gives good functional, clinical, and radiological outcomes, in stage 3 of Kienbock's disease with excellent rates of fusion with low complications. Even, in manual workers, scaphocapitate fusion can reliably provide good outcomes and this is maintained in the mid to long-term follow-up. Therefore, it should be considered as one of the procedures of choice.
