Purpose: We wanted to evaluate the result of percutaneous, mini-open reduction for the treatment of Mason II or III radial head and neck fractures. Materials and Methods: 13 patients (8 male, 5 female) with Mason II or III radial head and neck fractures were treated by 1 cm percutaneous mini-open reduction under fluoroscopy. The average age of our subjects was 29 years. Follow up duration was 18 months. Results: Union was noted in all cases. Mean radial neck angulation was decreased from 33.2 degrees to 7.8 degrees. The mean change in angulation between the immediate post-operative and last follow-up was 0.7 degrees. The mean range of motion at the elbow joint was at last follow up, 133.1 degrees in flexion, 7.3 degrees in extension, 80 degrees in pronation and 84.3 degrees in supination. Postoperatively, mean Mayo Elbow Performance Index, American Shoulder and Elbow Surgeons elbow score, and Disabilities of the Arm, Shoulder and Hand score were 96.2, 97 and 1.2. Temporary posterior interosseous nerve palsy (1 case) and minimal cubitus valgus deformity (1 case) were noted. Conclusion: Selected Mason II or III radial head and neck fractures can be treated satisfactorily with percutaneous mini-open reduction.

Purpose: This study examined the effects of a weekly teriparatide on the change in vertebral compression ratio, back pain, and vertebral fracture healing in osteoporosis patients with vertebral compression fractured induced by low energy trauma. Materials and Methods: From January 2016 to December 2017, 57 patients with severe osteoporotic vertebral fractures with a T score of -3.5 or less were included in this study. The changes in the vertebral compression ratio, visual analogue scale (VAS), Oswestry disability index (ODI) for at least 6 months were examined. The morphology of bone marrow edema and the presence of intervertebral cleft, osteocalcin, and N-terminal telopeptide (NTx) were also investigated. Results: The mean compression ratio was 20% in the experimental group (teripratide group) at 3 months, and 38% in the control group. A significant difference in the compression ratio of the vertebral body over time was observed (p<0.05; t-test). A comparison of the compression ratio of the vertebral body with the follow-up duration in each group showed no significant increase in the, compression (p=0.063) in the experimental group and a significant increase in the control group (p<0.05). The mean time to reach the plateau of the compression rate was one month in the experimental group and three months in the control group. The VAS score in the experimental and control group was 0.39 and 1.07 points, respectively. The ODI score in the experimental and control group was 33.72 and 39.52, respectively. At the last follow-up radiographs, there were no cases with an intervertebral cleft (0%) in the experimental group and 1 case (2.2%) in the control group. A significant difference in the osteocalcin level was observed between the injury and 6 months after the injury (p=0.003). In addition, there was no significant difference in the NTx level between the injury and 6 months after injury (p=0.960). Conclusion: In vertebral compression fractures patients with severe osteoporosis, a weekly teriparatide can promote the union of fractures, prevent further collapse of the vertebral body, and reduce the back pain faster.

Purpose: We wanted to analyze and report on the radiologic and clinical results of prospective Hook plate fixation for unstable distal clavicle fractures after a minimum of 2 years follow up. Materials and Methods: We followed up 17 out of 20 cases that underwent prospective Hook plate fixation from 2008 to 2009. We performed radiologic follow up at 2 weeks, 6 weeks, 3 months, 6 months, 18 months and 24 months postoperatively. The clinical results were evaluated at 12 months and 24 months postoperatively. Results: The mean period for bony fusion was 14.5 weeks and the plate was removed after an average of 20.2 weeks. The VAS pain scores were 0.7 and 0.8, the UCLA scores were 33.5 and 33.3, the ASES scores were 92.8 and 92.5, the Constant-Murley scores were 81.5 and 77.0, the KSS scores were 92.5 and 94.3 and the ranges of motion were $173.3^{\circ}$ and $173.7^{\circ}$ of flexion, $56.0^{\circ}$ and $54.5^{\circ}$ of external rotation, $62.3^{\circ}$ and $63.5^{\circ}$ of the internal rotation, $172.0^{\circ}$ and $172.6^{\circ}$ of abduction and $43.3^{\circ}$, and $42.9^{\circ}$ of extension at 1 and 2 years follow-up, respectively. There was no statistically significant difference of clinical outcomes and the range of motion at 1 year and 2 year postoperatively (p>0.05). There was no other complication except 1 case of delayed union. Conclusion: For Hook plate fixation at 2 years postoperatively, the complications will be decreased and excellent clinical results should occur.
