INTRODUCTION Osteoid osteoma is a painful, benign bone tumor that mainly affects young people. Thermocoagulation is one of the recommended percutaneous treatment methods. This study sought to assess its efficacy and identify risk factors for osteoma recurrence. METHODS Results were analyzed retrospectively for a group of 87 patients treated by thermocoagulation between 2002 and 2011. The recurrence rate was calculated and analyzed relative to patient and tumor characteristics. The treatment efficacy was determined and methods to prevent complications were analyzed. RESULTS The mean follow-up time was 34 months. The average patient age was 23 years. There were seven complications including three patients with delayed wound healing, mainly at tibial sites. The recurrence rate was 10.4%. The success rate for first-line treatment was 89.6% and it was 97.5% for second-line treatment. Analysis of patient characteristics and tumor locations revealed no risk factors for recurrence. CONCLUSION Percutaneous thermocoagulation is a reliable and effective technique that provides fast, long-lasting pain relief. However recurrence can occur even after the nidus is completely resected. These recurrences can be effectively managed by repeat treatment. Recent technical improvements have reduced the risk of thermocoagulation-related complications. LEVEL OF EVIDENCE IV.

BACKGROUND The objective of this study was to assess clinical and computed-tomography (CT) outcomes at least 2 years after humeral head resurfacing to treat concentric gleno-humeral osteoarthritis. HYPOTHESIS Humeral head resurfacing provides similar outcomes to those achieved with stemmed humeral head implants. MATERIALS AND METHODS This single-centre retrospective study included 40 Copeland™ and 65 Aequalis™ humeral resurfacing heads implanted between 2004 and 2012. Mean patient age at diagnosis was 64 years. The diagnoses were osteoarthritis with an intact (68%) or torn (21%) rotator cuff, avascular necrosis (5%), osteoarthritis complicating chronic instability (3%), post-traumatic osteoarthritis (2%), and chronic inflammatory joint disease (1%). Validated clinical scores, radiographs, and CT before surgery and at last follow-up were compared. RESULTS During the mean follow-up of 56 months, complications occurred in 24 implants. Revision surgery with reverse shoulder replacement was required in 18 cases, after a mean of 43.6 months, to treat glenoid wear or a rotator cuff tear. At last follow-up, for the implants that did not require revision surgery, the mean Constant score was 64/100. The implants had a mean varus of 5° and mean retroversion of -13.3°. The mean increase in glenoid cavity depth was 2.4mm. Mean increases in medial and lateral humeral offset were 1.9mm and 2.7mm, respectively. Pre-operative factors significantly associated with failure were rotator cuff tear (P=0.017) and glenoid erosion (P=0.001). DISCUSSION We found a high failure rate related to glenoid wear or progressive rotator-cuff impairment, although CT showed no evidence of implant malposition or overstuffing. Previous studies of stemmed humeral head implants showed better outcomes. Given the low medium-term prosthesis survival rate, we now reserve humeral head resurfacing for concentric osteoarthritis without glenoid erosions or rotator cuff damage. LEVEL OF EVIDENCE IV, retrospective study.
