Preoperative and post operative pain scores (visual analogue scale), ambulatory status, and patient satisfaction were measured.Anterior vertebral height, as well as the status and size of cement were assessed radiologically preoperatively, postoperatively, and at 3 months and 1 year.Results: Pain scores (visual analogue scale) and ambulatory status improved significantly after kyphoplasty and remained unchanged during follow-up. Overall patient satisfaction was 93%. Radiological findings showed that mean vertebral height was significantly higher than preoperative (p�0.05). According to follow-up radiological finding, we divided cases into 4 groups: Group 1, 2; maintained vertebral height with minimal or some cement resorption; Group 3, 4; cement crack resorption and vertebral collapse. Group 1, 2 and Group 3, 4 had 38 patients (84%) and 7 patients(16%) respectively. Revision surgery was needed in 3 cases (antero-posterior surgery in 2 cases of group 4, and decompression in 1 case of extravasation into the neural canal).Conclusions: Kyphoplasty with calcium phosphate may be a good alternative for treatment of osteoporotic vertebral fracture, but non-union of the vertebral body with a large cleft showed a high risk of premature resorption and collapse of the vertebral body. The presumed advantage over PMMA needs longer follow-up.

Multiple rice bodies are a rare disorder that is most commonly observed in chronic rheumatoid arthritis patients and as a complication of chronic inflammation in the bursa. However, it can occur in the absence of an underlying systemic disorder. Although it resembles synovial chondromatosis clinically and on imaging, the condition can be discriminated by an analysis of the radiographic and MR appearances. We encountered a case of multiple rice body formation with subacromial bursitis on the shoulder of a 37-year old man suffering from pain and motion limitation. The patient was treated by arthroscopic removal of the multiple rice bodies and a subacromial bursectomy. We present this case with a review of the relevant literature.
