RESUMO

PURPOSE: The aim of this study was to determine the effectiveness of arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy. MATERIALS AND METHODS: Between May of 2006 and July of 2014, a total of 43 patients who had undergone surgery for primary osteoarthritis of the elbow with ulnar neuropathy were included in this study. We divided the subjects into two groups according to the method of surgery: group 1 (n=18) received mini-open ulnar nerve decompression only, and group 2 (n=25) received arthroscopic debridement with mini-open ulnar nerve decompression. Patients were assessed for the following clinical outcomes: visual analogue scales (VAS) score, range of motion of the elbow joint, Mayo elbow performance score (MEPS), and disabilities of the arm, shoulder and hand (DASH) at the time before surgery and 6 months after surgery. We analyzed the recovery of the ulnar nerve by the McGowan grade and Bishop rating score preoperatively and at 6 months after the surgery. RESULTS: The VAS score, range of motion of the elbow joint, MEPS, and DASH showed significant statistical difference after the surgery (p <0.05). However, between the 2 groups, there was no significant difference. For the McGowan grade, all cases of both groups–except one case each group–showed at least one grade improvement. Moreover, group 2 showed a greater significant difference than group 1 (p=0.001). At the final follow-up, according to the Bishop rating score, group 2 had a greater significant difference than group 1 (p=0.036). CONCLUSION: Arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy is a useful technique, which has several advantages, including the benefits associated with a minimally invasive surgery and also the improvement of elbow joint function and excellent recovery of the ulnar nerve.

RESUMO

BACKGROUND: Bisphosphonates are generally known to adversely affect fracture healing because they inhibit osteoclastic bone resorption. However, some authors argue that bisphosphonates have no adverse effect on the restoration of the mechanical integrity of long bones after fractures. It is unclear whether bisphosphonates can be initiated safely in patients with acute proximal humerus fractures. The aim of this study was to determine whether the early use of a bisphosphonate affects healing and outcomes of osteoporotic proximal humerus fractures treated with a locking compression plate. METHODS: Between August 2004 and June 2013, a total of 82 osteoporotic patients who underwent locking plate fixation of proximal humerus fractures were enrolled retrospectively. The patients were divided into two groups according to the timing of the commencement of treatment with alendronate after surgery: group A (n = 34, initiation of the bisphosphonate treatment within two weeks after surgery) and group B (n = 48, control group, initiation of the treatment three months after surgery). Patients were assessed for radiographic union at 2, 6, 10, and 16 weeks, 6 months, and 1 year after surgery. Clinical assessments were performed using the Constant score and American Shoulder and Elbow Surgeons (ASES) score at 1 year after surgery. RESULTS: No significant differences were observed between the two groups with respect to radiographic and clinical outcomes after locking plate fixation. All patients obtained fracture union, and the mean time to radiographic union was similar in group A and group B (6.3 and 6.6 weeks, respectively; p = 0.67). CONCLUSIONS: This study shows that the early initiation of bisphosphonate treatment does not affect bone union or clinical outcomes in patients with an osteoporotic proximal humerus fracture treated by locking compression plate fixation.
