Purpose: The purpose of this study was to investigate usefulness of locking compression plate (LCP) as an open reduction technique by evaluating clinical results obtained from the patients with lateral malleolar fracture treated by internal fixation using LCP after open reduction. Materials and Methods: Among the patients with lateral malleolar fracture, the 28 patients who were treated by internal fixation using Locking compression plate after an open reduction and were able to be followed up for more than 6 months were included in this study. Final postoperative evaluation was done based on the Meyer's clinical and radiologic evaluation system. Results: All cases achieved anatomical reduction and fixation of the reduction postoperatively. 28 minutes were taken meaningly from the incision to the fixation of LCP plate after the anatomical reduction. Everage bony union time was 8.2 weaks, and the result was excellent in 23 cases (82%), good in 5 cases (17%) and poor result was abscent according to the criteria of Meyer et al. One case of post traumatic arthritis and one case of superficial infection on the operation site were found, but non-union, delayed union and malunion were not occurred. Conclusion: The internal fixation after open reduction using LCP is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including easy application and a greater stability due to its capability of maintaining exact anatomical reduction even though the screw does not penetrate the medial cortex of fibular to add the stability and rigidity of the fixation.

Background: Indirect reduction technique offers a valid option in the treatment of proximal humerus fracture. The purpose of this study is to evaluate the functional outcome and the complication rate after indirect reduction and internal fixation of unstable proximal humeral fractures with use of a locking plate. Methods: Twenty four patients with acute proximal humerus fracture were managed with indirect reduction and internal fixation with a locking plate. The mean follow-up period was 15.5 months. Results: The anatomical reduction of the medial cortex buttress was seen in 16 patients (66%) of the Group A and the non-anatomical reduction was seen in 8 patients (33%) of the Group B. Mean union time was $3.2{\pm}1.9$ months; it was $2.2{\pm}0.6$ months in the Group A and $5.3{\pm}2.2$ months in the Group B (p < 0.05). In our series, there were 6 cases of complications and these include 2 cases of varus malunion, 2 cases of shoulder stiffness, 1 case of heterotrophic ossification, 2 cases of screw perforation and 1 case of impingement. Conclusions: We conclude from our studies that indirect reduction and internal fixation using locking plate for acute proximal humerus fracture can give good results with bony union and predictable good overall functional outcome. If the medial cortex buttress is well maintained, a better anatomical reduction would be achieved, the union would be prompted, the pain would be further reduced and the range of the motion would be recovered more promptly.

Background: Unstable distal clavicles experience high non-union rates, prompting surgeons to recommend surgery for more predictable outcomes. There is a lack of consensus on the optimal method of surgical fixation, with an array of techniques described in the literature. We describe an alternative method of fixation involving the use of a distal clavicular anatomical locking plate with Fibertape cerclage augmentation in our series of patients. Methods: Nine patients (8 males and 1 female), with a mean age of 36 years, who sustained unstable fracture of the distal clavicle in our institution were treated with our described technique. Postoperative range of motion, functional and pain scores, and time to radiographic union were measured over a mean follow-up period of 10 months. Incidences of postoperative complications were also recorded. Results: At the last patient consult, the mean visual analog scale score was 0.88±0.35, with a mean Disabilities of the Arm, Shoulder, and Hand (DASH) score of 1.46±0.87 and American Shoulder and Elbow Surgeons (ASES) score of 94.1±3.57. The mean range of motion achieved was forward flexion at 173°±10.6°, abduction at 173°±10.6°, and external rotation at 74.4°±10.5°. All patients achieved internal rotation at a vertebral height of at least L2 with radiographical union at a mean of 10 weeks. No removal of implants was required. Conclusions: Our described technique of augmented fixation of the distal clavicle is effective, produces good clinical outcomes, and has minimal complications.

Tension band wiring of olecranon fractures is recognized as an effective method for fixation and union Complications as non-union, limitation of motion and subcutaneous k-wire protrusion are occasionally reported. But, there are no references about limitation of forearm rotation after tension band fixation. We report two cases of limitation of forearm rotation after tension band fixation of olecranon fracture.

Purpose: We analyzed and compared the clinical and radiologic results between minimally invasive plate osteosynthesis and internal fixation using intramedullary (IM) nail in the treatment of distal tibia fractures. Materials and Methods: From March 2005 to June 2013, 65 cases of distal tibia fractures treated with either plate fixation or IM nail fixation were analyzed retrospectively by clinical and radiologic evaluations. The clinical results were compared using the American Orthopaedic Foot and Ankle Society (AOFAS) score, Olerud-Molander ankle score (OMAS), and visual analogue scale (VAS) score at the last follow-up. The radiologic results were compared by time to bone union, complications such as nonunion, delayed union, and malunion. Results: The clinical results (according to OMAS, AOFAS score, and VAS score) were 77.47, 84.76, and 1.75, respectively, in the plating group, and 90.21, 91.00, and 1.25, respectively, in the nailing group, and there was no statistically significant difference. Plating group showed earlier union than the nailing group and the nailing group showed higher frequency of non-union and delayed union than plating group. Conclusion: In treatment of distal tibia fractures, two methods showed appropriate results. Therefore, thorough investigation of the types of fracture, state of soft tissues, and advantages and disadvantages of the two methods should be conducted in the treatment of distal tibia fractures.

Purpose: To evaluate the results of conservative treatment of zone I, II $5^{th}$ metatarsal base fracture. Materials and Methods: Between May 2004 and June 2010, a total of 58 patients of zone I, II $5^{th}$ metatarsal base fractures were included in this study. The mean length of follow-up was 13.5 months (12~36 months). All of the patients were treated with full-weight-bearing short leg cast immobilization for 4 weeks and wooden sole shoes for 4 weeks. The results were evaluated about the radiographic union, the midfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS), the tenderness on fracture site and other complications. Results: All patients were able to return to their prior levels of activity. The mean time for union as shown on radiographs was 45.5 days, and the mean midfoot scale of AOFAS was 99.7 points. There were no nonunions or refractures during the follow-up. Conclusion: The conservative treatment with full-weight-bearing short leg cast and wooden sole shoes seems to give good results for zone I, II $5^{th}$ metatarsal base fracture.

Purpose: To validate the major bony causes and postoperative results of the first metatarsal head plantar pain. Materials and Methods: We experienced one case of the fracture and non-union of the medial sesamoid treated by autogenous calcaneal bone graft, one case of the fracture and non-union and two cases of the hypoplasia of the medial sesamoid treated by excision of medial sesamoid, one case of the arthrosis between the first metatarsal head and the medial sesamoid treated by plantar 1/2 partial excision of the medial sesamoid, and two cases of the metatarsus primus nexus treated by basal metatarsal closing wedge osteotomy between October 1995 and September 1999. The mean follow-up period was 28 months. We evaluated the results by using of the clinical rating systems for the hallux and the radiographic findings. Results: An excellent results were achieved in all cases except one which was preoperatively diagnosed as metatarsus primus nexus. But, clinically this one case also satisfied with the postoperative result. Radiologically, We did not find the malunion or nonunion of the medial sesamoid treated by bone graft and of the metatarsus primus flex us treated by basal metatarsal closing wedge osteotomy. And also we did not find the postoperative fracture of the medial sesamoid treated by plantar 1/2 partial excision. There were no postoperative complications in all cases. Conclusion: We think that the good results may be achieved from the patients with the plantar pain of the first metatarsal head by the exact diagnosis and aggressive treatments.

Simple clavicle fractures can achieve satisfactory results through conservative treatment, and the less frequency of nonunion. Non-union or malunion can occur in displaced clavicle fractures or comminuted shaft fractures. Treatment of displaced comminuted clavicle shaft fractures is performed by holding together the free fragments with interfragmentary screws or wires and fixing them to the clavicle with a plate. Therefore, we performed interfragmentary fixation using open reduction and internal fixation with bioresorbable screws (Mg-Ca alloy, Resomet bioresorbable bone screw; U&I Corp.) and bioresorbable wires (Mg-Ca alloy, Resomet bioresorbable K-wire and pin, U&I Corp.) for displaced comminuted clavicle fractures (Robinson type 2B) and additionally used a metal plate. We expected decreased irritation and infection due to absorption after surgery. We report four cases that were treated in this way.

It has been known that the ankle arthrodesis is a common surgical procedure for treating the ankle arthrosis and deformity that do not respond to the non-operative treatment. To date, various surgical techniques for the ankle arthrodesis have been reported. Clinical and biomechanical trials have shown that the rigid internal fixation leads the increased rate of the union. The ankle arthrodesis may be complicated with the nonunion, delayed union, malunion, and infection. In cases of the Charcot joint of the ankle in diabetic patients, however, arthrodesis could reduce the disadvantage of the nonoperative treatment, such as the loss of the reduction, progressive collapse, multiple ulcerations and infection. The object of this case report is to report our experience of a successful ankle arthrodesis using an anterior T plate in treating the unstable ankle of a diabetic patient, associated with the ankle fracture and the neuropathy. The surgical approach of this technique is simple so that it would allow less soft tissue injury, and this procedure would be regarded as one alternative to provide the rigid internal fixation in the ankle arthrodesis.
