title: A comparison of treating Unicameral bone cyst using steroids and percutaneous autologous bone marrow aspiration injection.
abstract: OBJECTIVE
  To compare the results of percutaneous autologous bone aspiration injection and steroids injections in the treatment of unicameral bone cyst.
  
  
  METHODS
  The prospective study was conducted at Mayo Hospital, Lahore, from January 2008 to March 2014, and comprised patients diagnosed radiologically as a case of unicameral bone cyst. The patients were divided into two groups, with group 1 being treated with bone marrow aspiration injection, while group 2 was given steroids injection. Aspiration of bone marrow was done from tibial tuberosity.
  
  
  RESULTS
  The 30 patients in the study were divided into two groups of 15(50%) each. In group 1, 8(53.34%) patients and in group 2, 3 (20%) patients achieved healing after the first injection (p<0.05), while overall success rates were 13(86.67%) in group 1, and 11(73.33%) in group 2 (p> 0.05). The mean number of procedures required in group 1 was 1.57± 0.495 (range: 01-3) and for 2.19 ± 1.076 (range: 1-5) in group 2 (p<0.05), and mean interval-to-healing was 14.3 months ± 8.705 (range: 7-36) for group 1 and 12.5 months ± 7.88 (range: 4-32) for group 2 (p> 0.05).
  
  
  CONCLUSIONS
  Bone marrow aspiration injection was better than steroids in treating unicameral bone cyst.
