RESUMO
The relationship between long-term bisphosphonate usage and insufficiency fracture in osteoporotic elderly patients has been increased interest in recent years. Most reported insufficiency fractures are predominantly concentrated on proximal femoral shaft or pelvic bone. However, there was no report about insufficiency femoral neck fracture after long term use of bisphosphonate in domestic. We experienced a rare case of a 70-years-old woman who was diagnosed with bilateral insufficiency femoral neck fracture after 8 years use of alendronate. We performed an internal fixation using 6.5 mm diameter cannulated screws for the both insufficiency femoral neck fracture. Symptoms disappeared immediately after the surgery and there was no radiologic and clinical complication such as nonunion or delayed union up to the latest follow-up at 12 months postoperatively.

BACKGROUND: Arthroscopic rotator cuff repair generally has a good clinical outcome but shoulder stiffness after surgery due to subacromial adhesion is one of the most common and clinically important complications. Sodium hyaluronate (HA) has been reported to be an anti-adhesive agent in a range of surgical procedures. However, there are few reports of the outcomes of arthroscopic rotator cuff repair of the shoulder. This study examined whether a subacromial injection of HA/carboxymethylated cellulose (CMC) affected the postoperative shoulder stiffness and healing of rotator cuff repair, as well as the safety of an injection. METHODS: Between January 2008 and May 2008, 80 consecutive patients with arthroscopic rotator cuff repair were enrolled. The patients were assigned randomly to the HA/CMC injection group (n = 40) or control group (n = 40). All patients were evaluated using the visual analog scale (VAS) for pain, passive range of motion at 2, 6 weeks, 3, 6, 12 months after surgery, and the functional scores at 6, 12 months postoperatively. Cuff healing was also evaluated using CT arthrography or ultrasonography at 6 or 12 months after surgery. RESULTS: The HA/CMC injection group showed faster recovery of forward flexion at 2 weeks postoperatively than the control group but the difference was not statistically significant (p = 0.09). There were no significant difference in pain VAS, internal rotation, external rotation and functional scores between two groups at each follow-up period. The functional scores improved 6 months after surgery in both groups but there were no differences between the two groups. The incidence of unhealed rotator cuff was similar in the two groups. There were no complications related to an injection of anti-adhesive agents including wound problems or infections. CONCLUSIONS: A subacromial injection of an anti-adhesive agent after arthroscopic rotator cuff repair tended to produce faster recovery in forward flexion with no adverse effects on cuff healing. However, its anti-adhesive effects after rotator cuff repair should be considered carefully with further studies.

PURPOSE: The aim of this study was to examine the dose-related effect of extracorporeal shock wave therapy (ESWT) for lateral epicondylitis. MATERIALS AND METHODS: Thirty patients with refractory lateral epicondylitis despite conservative treatment for 6 months were enrolled in this study. The patients were divided randomly into a low- and highenergy group. All patients were treated 3 times with ESWT with an interval of 1 week in a double blinded manner. The mean energy level in the low- and high-energy group was 0.12 mJ/mm2 and 0.24 mJ/mm2, respectively. The upper extremity functional scales and Mayo elbow scores were measured prospectively at the baseline, 1, 3 and 6 months after ESWT. RESULTS: Significant clinical improvement was observed in both groups after ESWT. The high-energy group showed better pain improvement at 6 months after ESWT (p=0.019). The effect of ESWT was dominant between 1 and 6 months after ESWT than within 1 month. CONCLUSION: ESWT for lateral epicondylitis demonstrated showed good results regardless of the energy dose. However, a high-energy level was more effective in pain improvement after 6 months of treatment.

PURPOSE: To evaluate the outcome of hemiarthroplasty with bone block graft and low profile prosthesis (Aequalis(R) fracture prosthesis) for the comminuted proximal humerus fractures. MATERIALS AND METHODS: Sixteen low profile prostheses were used since July 2004, and 11 patients were followed-up for average 19.9 (12~30) months. Their mean age was 67.3 (52~78) years. Pain and satisfaction visual analog scale (VAS), range of motion, and modified UCLA score for hemiarthroplasty were evaluated at every visit. Radiography was also checked for stem position, loosening, and tuberosity union. RESULTS: Mean pain VAS was 2.7 (0~5), and mean satisfaction VAS was 8.4 (5~10). Mean active forward flexion was 137 degrees (90~170), external rotation at side was 45.5 degrees (25~70), and internal rotation at back was T10 (T7~L1). Modified UCLA score was 19 (12~30) at final visit. All stems were stable, and there were no loosening at the final follow-up. All tuberosities were united except two tuberosity absorptions. CONCLUSION: The outcome of hemiarthroplasty with bone block graft and low profile prosthesis was comparable to other implants for comminuted proximal humerus fractures. This system had unique advantages for tuberosity union. Further study with more patients and longer follow-up are necessary to clarify the effectiveness of this prosthesis.

PURPOSE: Parsonage-Turner syndrome is a rare disorder with sudden onset of severe pain around the shoulder girdle, followed by weakness of the shoulder muscles. The purpose of the current study was to describe the clinical features associated with this condition and to review the literature. MATERIALS AND METHODS: A retrospective study of the Parsonage-Turner syndrome was carried out for 6 patients seen from December 2005 to July 2008. The clinical and radiographic data was collected by medical records and telephone interviews. Five patients were males and one was female with ages ranging between 20-68 years (mean, 43.5). The mean follow-up period was 19.1 months (range, 14-27 months). RESULTS: The intense pain around shoulder continued for 1 day to 3 weeks and decreased spontaneously at a mean of 3.3 weeks (range, 2-5 weeks) after onset of pain. Weakness in the involved muscles had developed at a mean of four weeks (range, 2-7 weeks). At the end of follow-up, five patients had an improvement of their strength and one patient had regained full strength. Electromyography was the most helpful in diagnosis. CONCLUSION: Parsonage-Turner syndrome is a self-limited disorder with a good outcome. Understanding of the course will assist in the diagnosis and treatment.
