Unilateral pedicle stress fracture accompanying spondylolytic spondylolisthesis is rare even in the elderly. Most are associated with major trauma, previous spine surgery, or stress-related activity. Here, the authors describe an unique case of unilateral pedicle fracture associated with spondylolytic spondylolisthesis at the L5 level, which was successfully treated by posterior lumbar interbody fusion with screw fixation at the L5-S1 level. As far as the authors' knowledge, no such case has been previously reported in the literature. The pathophysiological mechanism of this uncommon entity is discussed and a review of relevant literature is included.

Calcaneus fracture with a subtalar dislocation are extremely rare. A case of a joint depression type calcaneus fracture with a lateral dislocation of the calcaneal posterior facet and tuberosity is presented. We treated it with open reduction and internal fixation with Steinmann pins and K-wires through limited posterior approach and obtained satisfactory radiographic and clinical outcome.

Purpose: To evaluate the clinical and radiological results of internal fixation with tension band wiring for the fracture at the base of fifth metatarsal bone. Materials and Methods: From January 2008 to December 2009, 15 cases with displaced fracture at the base of fifth metatarsal were analyzed and average follow up period was 13.8 months. Lawrence classification was used to classify fracture type. We evaluated clinical results by American Orthopedic Foot Ankle Society (AOFAS) midfoot score and radiological results by union time. Complications was also checked. Results: According to classification, zone I fracture were 11 cases and zone II fracture were 4 cases. Bony union was achieved in all cases after 7 weeks. In the final follow-up, average AOFAS score was 94. There were no complications except hardware irritation. Conclusion: Satisfactory results were obtained after tension band wiring for the fifth Metatarsal base fracture in zone I fracture or comminuted zone II fracture for which it is not easy to be fixed with screw.

Purpose: The aim of this study was to evaluate the complications of open reduction and internal fixation of mandibular fracture with miniplates. Patients and Methods: A total of 134 patients who presented with 196 fractures were analyzed retrospectively. Complications were evaluated for factors such as age, the site of fracture, the severity of fracture, delayed operation, preoperative wound contamination, the site and disposition of teeth in the fracture line and midfacial fractures. Statistical analysis was used to compare complications to risk factors. Results: Of the 134 patients, 20 patients had some form of postoperative complications and complication rate was 14.9%. These complications included infection, plate fracture, malocclusion, wound dehiscence, nerve injury and nonunion. There was a significant correlation between complication rate and the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth(p<0.05). Conclusion: The occurrence of postoperative complications in the treatment of mandibular fractures was related to the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth.

목적: 방사선 소견에서 슬개골 골절이 발견되었을 때 치료 방침 결정에 초음파 영상의 임상적 유용성을 알아보고자 하였다. 대상 및 방법: 2006년 3월부터 2009년 9월까지 슬개골 골절로 치료받은 20명 20예를 대상으로 하였으며, 남자가 8예, 여자가 12예였고, 우측이 13예, 좌측이 7예였으며, 평균 연령은 43세(14~72세)였다. 초음파를 이용하여 굴곡-신전시 슬개 지대 파열 여부를 보는 Drayer 검사와 연계하여 치료 방침을 결정 하였다. 횡 골절이 10예, 종 골절이 8예, 분쇄 골절이 2예가 있었으며, 초음파를 이용하여 슬개 지대의 파열 유무와 Drayer 검사가 양성인지 음성인지를 보았다. 결과: 슬개 지대가 파열되지 않은 12예의 경우 전예에서 Drayer 검사는 음성이었으며, 별도의 고정 없이 보행을 허용하여 보존적 치료를 하였다. 슬개 지대가 완전 파열된 4예는 Drayer 검사가 양성이었으므로 관혈적 정복술을 시행하였고, 슬개 지대가 부분적으로 파열되어 Drayer 검사가 음성이었지만, 골절의 전위가 2 mm 이상인 2예는 비관혈적 나사 고정술로 좋은 임상적 결과를 보였다. 결론: 슬개골 골절에서 초음파는 방사선 소견, Drayer 검사와 연계하여 치료 방침을 결정 하는데 유용한 검사 방법 중의 하나로 생각된다.

Post-traumatic pseudoaneurysms of internal maxillary artery are rare, but may be life-threatening. When arterial damage leads to pseudoaneurysm formation, delayed intractable epistaxis can occur. We report our experience with the diagnosis and management of a ruptured internal maxillary arterial pseudoaneurysm that was discovered preoperatively in a patient with a zygomaticomaxillary complex (ZMC) fracture. He presented to the emergency room with epistaxis, which ceased shortly, and sinus hemorrhage was observed with a fracture of the posterior maxillary wall. The patient was scheduled for open reduction and internal fixation (ORIF) of the ZMC fracture. However, immediately before surgery, uncontrolled epistaxis of unknown origin was observed. Angiography indicated a pseudoaneurysm of the posterior superior alveolar artery. Selective endovascular embolization was performed, and hemostasis was achieved. After radiologic intervention, ORIF was successfully implemented without complications. Our case shows that in patients with a posterior maxillary wall fracture, there is a risk of uncontrolled bleeding in the perioperative period that could be caused by pseudoaneurysms, which should be considered even in the absence of typical symptoms.

Background Hand fractures can be treated using various operative or nonoperative methods. When an operative technique utilizing fixation is performed, early postoperative mobilization has been advocated. We implemented a protocol involving controlled active exercise in the early postoperative period and analyzed the outcomes. Methods Patients who were diagnosed with proximal phalangeal or metacarpal fractures of the second to fifth digits were included (n=37). Minimally invasive open reduction and internal fixation procedures were performed. At 3 weeks postoperatively, controlled active exercise was initiated, with stress applied against the direction of axial loading. The exercise involved pain-free active traction in three positions (supination, neutral, and pronation) between 3 and 5 weeks postoperatively. Postoperative radiographs and range of motion (ROM) in the interphalangeal and metacarpophalangeal joints were analyzed. Results Significant improvements in ROM were found between 6 and 12 weeks for both proximal phalangeal and metacarpal fractures (P<0.05). At 12 weeks, 26 patients achieved a total ROM of more than 230° in the affected finger. Postoperative radiographic images demonstrated union of the affected proximal phalangeal and metacarpal bones at a 20-week postoperative follow-up. Conclusions Minimally invasive open reduction and internal fixation minimized periosteal and peritendinous dissection in hand fractures. Controlled active exercise utilizing pain-free active traction in three different positions resulted in early functional exercise with an acceptable ROM.

Purpose: This study aimed to evaluate the outcomes, including the complications, of open reduction and internal fixation using a headless cannulated compression screw for a fifth metatarsal base fracture. Materials and Methods: We retrospectively investigated 11 patients with 5th metatarsal base fracture who were treated with a headless cannulated compression screw. The mean follow-up period was 13 months (8~15 months), and the mean age was 46.5 years (21~70 years). We analyzed the patients' sex, age, time to union, amount of fracture displacement, and complications. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score was used for clinical assessment. Results: The average amount of displacement decreased significantly from 3.4 mm (2.1~5.2 mm), preoperatively, to 0.4 mm (0~1.3 mm), postoperatively (p<0.001). The average bone union time was 54.1 days (41~68 days). There were no complications, such as a metal failure, irritation, and loss of a reduction. The mean AOFAS midfoot score was 97.7 (90~100) at 6 months, postoperatively. Conclusion: We suggest that a headless cannulated compression screw for 5th metatarsal base fracture is a useful and alternative method for a firm fixation without complications.
