Purpose: To evaluate the clinical outcomes and radiographic results of open reduction and internal fixation for intraarticular calcaneal fractures. Materials and Methods: We reviewed 20 cases of calcaneal fractures managed with open reduction and internal fixation from March 2003 to January 2005. We used the computed tomographic classification system proposed by Sanders et al to classify these fractures. Preoperative and postoperative Bohler's angle, heel height (calcaneal facet height) and calcaneal length, calcaneal width were measured. The Creighton-Nebraska Health Foundation Assessment score was used for clinical evaluation. Results: There were 12 cases of type II fractures, 5 of type III fractures and 3 of type IV fractures. The mean clinical score was 84.3 for type II, 82.6 for type III and 56.1 for type IV. The mean preoperative $B{\ddot{o}}hler$ angle was $6.1^{\circ}$ and final was $22.8^{\circ}$. The mean preoperative calcaneal facet height was 76.6 mm and final was 80.3 mm (The mean calcaneal facet height was changed from preop 76.6 mm to postop 80.3 mm). The mean preoperative calcaneal length was 88.2 mm and final was 92.6 mm. The mean preoperative width was 38.1 mm and final was 35.6 mm. Conclusion: Open reduction and internal fixation showed good results for type II and III fractures, but for type IV fractures the clinical result was significantly worse than the other types. However, type IV fractures still had restoration of (should be restored in) $B{\ddot{o}}hler's$ angle, calcaneal facet height, calcaneal length and width which may be helpful in later subtalar fusion.

Purpose: The purpose of this study is to analyze the clinical and radiological results of minimally invasive percutaneous screw fixation in intra-articular calcaneal fractures and its complications. Materials and Methods: This study is based on 30 intra-articular calcaneal fractures that treated by index operation from June 2005 to November 2006 with at least 6 months follow-up. We assessed the clinical and radiological outcomes and complications. Results: According to Sanders classification, there were 8 in type IIA, 7 in type IIB, 3 in type IIIAB, 6 in type IIIBC, 6 in type IV. And according to Essex-Lopresti classification, there were 9 in the tongue type, 21 in the joint depression type. Average follow-up period was 14.6 months (range: 6-23 months). Average interval between from injury to operation was 2.3 days. Average AOFAS score was 87.7 (range: 52-92). Satisfactory results were obtained in 22 cases (73.3%) by AOFAS score and in 20 cases (66.7%) by VAS score (mean: 3.4). Radiological results improved from 8.7 to 20.3 degrees in the Bohler angle and from 40.2 mm to 52.1 mm in calcaneal height. Postoperative complications were 2 skin and soft tissue problems and 1 sural neuropathy. Conclusion: Minimally invasive percutaneous screw fixation may be useful alternative surgical method in the management of Sanders type II and III calcaneal fractures, which is possible to achieves the anatomical restoration and minimizes postoperative complication in patients with high risks of soft tissue compromise and allows relatively early operation.

Purpose: To evaluate the clinical results and determine appropriate methods of surgical treatment about type II talar neck fracture. Materials and Methods: Among nineteen patients who received surgical treatment for type II talar neck fracture from May 2000 to May 2005. Fourteen patients with a follow-up period of more than 1 year were divided into two groups. Six patients reduced by closed reduction (Group A) with screw fixation and eight patients reduced by open reduction with screw fixation. We analyzed preoperative, postoperative and follow-up simple radiographs and reviewed patient hospital records retrospectively. Clinical results were evaluated by Hawkins scoring system. We analyzed pain, limp, range of motion of ankle and subtalar joint. Results: Five patients (83.3%) in group A and seven patients (87.7%) in group B had excellent and good clinical results. There were no complications including avascular necrosis, delayed union, nonunion. Conclusion: Closed reduction with screw fixation of talar neck fracture shows correct reduction and satisfactory results. But because of short term period of follow-up, we need long term results.

Purpose: This study was performed retrospectively and to compare the clinical outcomes of the surgical management using Antiglide plating and lateral plating for Danis-Weber type B isolated lateral malleolar fractures. Materials and Methods: Between March 2004 and March 2009, 92 patients were followed up for more than 6 months after surgical treatment. 49 patients were treated with Antiglide plating, whereas the remaining 43 patients underwent lateral plating. The results of the two groups were analyzed both radiographically and clinically using Ankle scoring system. Results: Both groups were comparable for age, sex distribution, time to surgery, and operation time. Bone union was noted at average of 8 weeks in all fractures. The mean ankle score was similar in both groups (94% versus 93%). Conclusion: Antiglide plating for Danis-Weber type B isolated lateral malleolar fracture is one of the good methods which has some advantages such as early ankle motion, ambulation and smaller operative incision.

Purpose: To evaluate the results of open reduction and internal fixation for displaced talar neck fracture. Materials and Methods: Fourteen patients were followed for more than 1 year after open reduction and internal fixation of displaced talar neck fracture. The mean age was 41.5 years, and the mean follow-up period was 3.8 years. There were 10 type II, 3 type III and 1 type IV fractures per Hawkins. There were 3 open fractures. Clinically AOFAS ankle-hindfoot scale and Hawkins criteria were utilized. Radiologically quality of reduction, duration of bony union, avascular necrosis and posttraumatic arthritis were evaluated. Results: At last follow-up, AOFAS scale was mean 89.1 points. There were 8 excellent, 4 good, and 2 fair results according to Hawkins criteria. Radiologically anatomical reduction was obtained in 13 cases. Mean duration of bony union was 11.8 weeks. There were 3 avascular necrosis and 2 post-traumatic arthritis. There was no significant difference in the incidence of avascular necrosis between early operation group and surgically delayed group. Conclusion: Accurate open reduction and rigid internal fixation seem to be prerequisites for satisfactory treatment of a displaced talar neck fracture.

Fractures located at the metaphyseal/diaphyseal junction at the base of the fifth metatarsal were first described by Sir Robert Jones in 1902. However, ever since, there has been disagreement and debate regarding the diagnosis, classification, pathomechanics, the incidences, and potential causes of delayed unions and nonunions, and the optimal method of treatment. It appears to be widely agreed that proximal fractures of the metaphyseal/diaphyseal region of the fifth metatarsal are prone to delayed union or even nonunion. Several classifications of proximal fifth metatarsal stress fractures have been devised. Torg et al. classified fractures involving the proximal part of the diaphysis of the fifth metatarsal into three types. The Torg classification is a good grading system that can be used to determine the type of surgery needed as well as for the prediction of prognosis. The ''plantar gap'' might add to the decision-making process for surgery and improve the prediction of patient prognosis. In addition, the new classification using 'plantar gap' might be used for classification of fifth metatarsal stress fracture. Fifth metatarsal stress fractures can be treated conservatively or surgically, and excellent results have been reported for surgery with rapid recovery in athletes. Intramedullary screw fixation has become a popular form of fixation for fifth metatarsal stress fractures. Bone grafting presents the problems of a longer recovery time and additional skin incision for harvesting. The modified tension band wiring is an useful and simple option for surgical treatment of challenging fifth metatarsal stress fractures.
