Mid term results of radial metaphyseal core decompression on Kienbock's disease

Abstract

OBJECTIVE: Kienbock's disease is a commonly seen posttraumatic avascular necrosis characterized by avascular necrosis of the lunate bone of the wrist which involves the dominant hand. In our study, we aimed to present midterm outcomes of 12 cases treated with radial metaphyseal core decompression.

PATIENTS AND METHODS: In our clinic, 12 patients who applied to our outpatient clinic with intractable pain despite at least six weeks of conservative treatment were previously diagnosed and evaluated as Kienbock's disease between the years 2006 and 2014. Patients at early stage received radial metaphyseal core decompression.

RESULTS: The patients were evaluated as postoperative grip strength, flexion-extension gap, ulnar-radial deviation gap, VAS, Quick DASH and MAYO wrist scoring and patient satisfaction.

CONCLUSIONS: We determined that interventions performed for Kienbock's disease cannot halt radiological progression. We are of the opinion that radial metaphyseal core decompression, aiming at increasing blood perfusion, improve early diagnosis and treatment of Kienbock's disease, increasing the patient satisfaction.
