title: Arthroscopic ablation of an osteoid osteoma of the elbow: a case series with a minimum of 18 months' follow-up.
abstract: BACKGROUND
  Arthroscopic excision of an osteoid osteoma was first reported in the knee joint; since then, there have been several reports of arthroscopic excisions in the knee, shoulder, and elbow, with inconclusive outcomes because of a limited number of cases. The aim of this prospective study was to evaluate the medium-term functional effects of arthroscopic ablation in cases of an osteoid osteoma around the elbow.
  
  
  METHODS
  We treated osteoid osteoma of the elbow through arthroscopic ablation in 10 patients. The arthroscopic resection procedure was performed 23 ± 9 months (range, 12-36 months) after initial symptoms. At the preoperative examination and last follow-up examination, the elbow flexion-extension and forearm supination-pronation ranges of motion were measured. The patients were assessed by the Mayo Elbow Performance Score, the visual analog scale for the elbow and wrist, and the Quick Disabilities of the Arm, Shoulder, and Hand score. Finally, the patients' general satisfaction was assessed.
  
  
  RESULTS
  The postoperative elbow flexion-extension range of motion was significantly higher compared with range of motion before surgery (P = .001; r = 0.86). According to the Mayo Elbow Performance Score, the average score increased significantly at the final follow-up examination. The mean preoperative and final Quick Disabilities of the Arm, Shoulder, and Hand scores were 47 ± 14 and 1.6 ± 2.8, respectively (P < .001). All patients were satisfied with the operation result.
  
  
  CONCLUSIONS
  According to the results of our study, arthroscopic ablation is a safe and efficient method of treatment for osteoid osteoma of the elbow, with a fast rehabilitation time.
