Purpose: To evaluate the efficiency of the minimally invasive percutaneous plate osteosynthesis (MIPPO) with locking compression plate (LCP) for distal tibial metaphyseal intra-articular fracture compared with extra-articular fracture. Materials and Methods: From February 2006 to June 2008, 21 patients with distal tibia metaphyseal intra-articular fracture and 20 patients with extra-articular fracture were treated operatively by MIPPO technique with LCP and followed for at least one year. In the group with intra-articular fracture, mean age was 48.85 years old and a mean follow-up was 15 months. In the other group with extra-articular fracture, mean age was 52.35 years old and a mean follow-up was 14.5 months. The type of fracture was evaluated using the AO/OTA classification and open-fractures were according to the Gustilo-And gron classification. Radiologic evaluation with fracture healing and tibial alignment, clinical evaluation with Olerud and Molander ankle score and restriction of motion were done for treatment. Results: According to AO/OTA classification, There were 21 type A, 15 type B, 5 type C. Average union time of the intra-articular fracture (type B, C) was 18.7 weeks. Average union time of the extra-articular fracture (type A) was 17.1 weeks. All fractures were healed without malunion. There were no difference of mean restriction angle between intra-articular fracture (ankle dorsiflexion was 3.57 degree, plantar-flexion was 5.95 degree) and extra-articular fracture (ankle dorsiflexion was 3 degree, plantar-flexion was 3.75 degree). There were no difference of Olerud and Molander ankle score between them as a mean score of intra-articular and extra-articular was 89.25, 91.25 each other. As a complication, there were 3 case of skin necrosis, 8 case of discomfortable skin tenting by plate and 1 superficial infection, but could be healed by conservative care. Conclusion: MIPPO technique, combined articular reduction, with LCP of distal tibial metaphyseal fracture was a good method with high functional recovery.

Purpose: The purpose of this study fracture. Materials and Methods: The clinical and radiological analysis were performed on 19 cases of the talus neck fractures who had been treated with conservative treatment or variable methods of operative treatment. Each cases followed up more than 1 year and 6 months from May 1989 to June 2001. The clinical results were analyzed according to the age, cause of injury, fracture type of Hawkins classification, associated soft tissue injury, method of treatments, complications, and Hawkins scoring system. Results: According to Hawkins classification, type I was 6 cases(32%), type II was 5 cases(26%), typeIII was 7 cases(37%), and typeIV was 1 case(5%). In all cases, complete bony union was obtained. According to the Hawkins scoring system, 8 cases(42%) were excellent and good. Avascular necrosis was 4 cases(25%). Traumatic arthritis was 10 cases which were occurred in type II, III and IV. An ankle fusion was 1 case. Conclusion: In talar neck fractures, non-displaced fracture treated by the cast immobilization and displaced fracture treated by early open reduction and internal fixation were expected good results. The complications were 77% of traumatic arthritis and 31% of avascular necrosis in type II, III and IV. We should preoperatively explain to the patient for high complication rates of traumatic osteoarthritis and avascular necrosis in the talus neck fractures.

The triplane fracture has been described as a fracture of the distal tibial epiphysis occurring across three planes-sagittal, transverse and coronal. The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture. According to Dias-Tachdjian classification, triplane fracture is classified two part fracture, three part fracture, four part fracture and two part fracture with extension to the medial malleolus. Among four types, two part triplane fracture with extension to the medial malleolus is a relatively rare injury and generally is not treated by closed reduction. Such fractures should have an anatomic reduction and adequate fixation to restore the joint congruity and obtain an anatomic reduction of the growth plate to prevent a future growth deformity. This is usually best accomplished with an open reduction and screw fixation or k-wire fixation. We experienced two part triplane fracture with extension to medial malleolus and check the CT to define the extent of the injury completely. And then we underwent open reduction and screw fixation for the fracture. As a result, we present four cases of two part triplane fracture with extension with review of related literatures.

Purpose: To compare the radiographic evaluations between two radiographic views (AP and lateral views) and four radiographic views (AP, lateral and both oblique views) in ankle fractures. Materials and Methods: From January 2000 to June 2002, 60 cases of ankle fractures were treated with open reduction and internal fixation and its followed up periods were at least 2 years. All cases were classified into three groups according to the method of preoperative radiographic evaluation. Two radiographic views (AP and lateral views) were taken in group A and four radiographic views (AP, lateral and both oblique views) were taken in group B. 12 Cases were evaluated with three dimensional computed tomography (3D CT). Four radiographic views and 3D CT were taken in group C. All cases were classified according to the Danis-Weber and Lauge-Hansen classification. Displacement of fracture fragment of medial, lateral, posterior malleolus and size of fracture fragment of posterior malleous were measured using picture archiving communication system (PACS). Results: Although kappa value between two or four radiographic views were good or excellent in Danis-Weber classification and Lauge-Hansen classification of ankle fractures, the displacements of medial and lateral malleoli were statistically different. Four radiographic views evalulated the degree of displacement of medial and lateral fragments more accurately compared to two radiographic views. Conclusion: Four radiographic views will be more useful than two radiographic views to decide the method of treatment and operation considering the displacement of fracture fragment.

Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed healing of the fracture in most cases, but skeletal deformity may develop in some cases. Therefore we should take plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

Purpose: The optimal management for ankle fracture in elderly patients remains controversial. This study was undertaken to review the results of surgical treatment of ankle fracture in the elderly and to compare with other studies. Materials and Methods: The participants in this study were 33 patients over the age of 65(average 71.5 years) who underwent surgical treatment of ankle fracture from January 2004 to December 2011. The study was a retrospective review of outcomes after open reduction and internal fixation (ORIF) of ankle fractures. To measure the clinical outcomes, we assessed postoperative complications, the pre- and post-operative mobility status, fracture union status, the time of fracture union and the AOFAS (American Orthopaedic Foot and Ankle Society) Ankle-Hindfoot scale. The level of patient satisfaction was also identified. Results: Delayed wound healing occurred in three patients(9.1%) but their wounds healed with repeated dressings without additional surgical treatment. Malunion occurred in one patient(3%). One patient(3%) had postoperative infection but healed with antibiotic treatment. 24 patients(96%) returned to preoperative mobility status. VAS score was lower than 2 in all patients. Bone union occurred with the 3.8 months (average months) after the surgery in all patients. Average AOFAS score was 87.4 and these were similar results as other studies of young patients. All patients were satisfied with surgical outcomes according to interviews. Conclusion: Surgical treatment of ankle fractures in the elderly can carry a significant risk of delayed wound healing and infection but incidence is relatively low. Internal fixation of ankle fractures in the elderly can be undertaken safely and the majority of patients can expect good outcome.

The fracture and fracture-dislocation of the neck of the talus (Hawkins' type I-IV) are uncommon injuries and represent only 0.12 to 0.32% of all fracures. Authors clinically evaluated in 12 cases Whom treated fracures of the neck of the talus, at department of orthopaedic surgery, Sun General Hospital, from 1990 to 1996, and the following results are obtained. 1. Of 12 cases, there were 11 males and 1 female, average age was 30 years. 2. Causes of fracture was fall down injury in 7 cases(58%), traffic accident in 4 cases(33%), direct trauma in 1 case(8%). 3. According to the classification by Hawkins' type I in 2 cases(17%), type II in 7cases (58%), type III in 3cases(25%). 4. Associated injuries were calcaneal fracture in 3 cases, fracture-dislocation of talus in 3 cases, subtalar dislocation in 3 cases, medial malleolar fracture in 5 cases, soft tissue injury in 3 cases, femur and tibia fracture in 1 case, and lumbar Spine compression fracture in 1 case. 5. Average time to operation after injury was 2.5 days. 6. In 2 cases were treated conservatively and 10 cases were treated open reduction and internal fixation with screw or K-wire. 7. Complications were avascular necrosis in 4 cases, post traumatic arthritis in 2 cases, skin necrosis in 4 cases, and then ankle fusion was done in 2 cases. 8. High rate of complication was seen in the talar neck fracture associated with calcaneal fracture. In the analysis of above results, evaluated by Hawkins' scoring system were excellent to fair in 75%.

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.

Unicameral bone cysts are benign solitary lesions that occur in the first two decades of life and with a greater frequency in the humerus and femur. The cyst is usually asymptomatic unless a fracture or impending fracture is present. The traditional method of treating unicameral cysts has been curettage with bone graft or steroid injection. Also, pathologic fractures in the calcaneus, unlike in other bones, are reported especially in the children to be nonexistent. In general, closed treatment was recommended for most of the calcaneal fractures in children, but suggested open reduction when joint displacement was severe. We report a case of displaced intraarticular fracture of the calcaneus with unicameral bone cyst in a child treated by classic curettage, allograft and open reduction with screw fixation.
