Abstract
OBJECTIVE: The aim of this study was to report the short-term results and complications of partial humeral head resurfacing (HemiCup®) in patients treated by avascular necrosis. MATERIAL AND METHODS: Between 2010 and 2014, 9 patients who underwent partial resurfacing of humeral head were evaluated. All the patients were treated by avascular necrosis. The mean follow-up was 44 months (minimum 24 months). The average age was 47 years (range 32-57 years). The patients were evaluated clinically and radiologically. Complications were reported. RESULTS: The patients had a significant improvement in functional scores and mobility between the pre-operative and last follow-up control. The Constant score improved from 35 to 79 points (P<.001), ASES score improved from 31 to 76 points (P<.001), forward flexion and external rotation improved from 101 to 150° (P<.001), and from 24 to 45° (P<.001), respectively. One patient presented symptomatic glenoid wear during follow-up, requiring revision surgery. CONCLUSION: In our patients treated by avascular necrosis, the partial resurfacing of humeral head (HemiCup®) demonstrated a significant improvement in functional scores and mobility with an average follow-up of 44 months.
