Purpose: The purpose of this study is to report the results of culture test at the time of removal of metal devices used for management of ankle fractures and for analysis of contributing factors. Materials and Methods: We reviewed medical records of 132 patients with lower tibia and ankle fracture who had their metal devices removed during the period from January 2010 to February 2014. Patients with clinical signs of infection were excluded. Culture test was performed by taking the granulation tissue around the metal device at the time of removal. We divided the subjects into two groups, culture positive and negative. We then performed a retrospective review of each medical record of multiple factors that might contribute to the culture results, including laboratory results, medical history, material and size of metal device, indwelling period, and whether or not it was open injury. Results: Among 132 cases, six were culture positive. Enterococcus was detected in two cases and the others were Staphylococcus. No significant difference in medical history of patients and laboratory results, including C-reactive protein level, was observed between the culture positive and negative group. Culture positive rate was 5.4% in titanium and 3.9% in stainless steel. In terms of metal size, culture positive rate was 5.1% in small plates, 6.7% in large plates, and culture negative in intramedullary nails. The average indwelling period of metal device was 61.5 weeks in the culture positive group, and 68.6 weeks in the negative group. Nine cases were open fractures and all were in the culture negative group. Conclusion: Whether or not the culture result was positive, there were no meaningful contributing factors. Presence of bacterium on the metal device could not be screened by any laboratory results or other factors.

Purpose: The treatment of calcaneal fractures remains a controversy in orthopaedic field because of its complications. The purpose of this study is to evaluate the efficacy of the treatment of calcaneal fractures and its complications. Materials and Methods: Clinical and radiological results were retrospectively analyzed in 28 patients, 34 cases with fractures of calcaneus which were treated in our department from September 1998 to march 2003. Results: According to the Creighton-Nebraska Foundation Assessment score, there were 3 excellent, 11 good, and 12 fair 6 poor results. Bohler angle was corrected from $8.3^{\circ}$ to $18.3^{\circ}$, Gissane angle was corrected from $121^{\circ}$ to $135^{\circ}$, and calcaneal width was corrected from 46.8mm to 37mm. Conclusion: Open reduction and internal fixation for joint depression type calcaneal fractures thought to be a good method of treatment. Closed reduction and percutaneous axial pinning should be chosed in selected cases of tongue type fractures. In treatment of complicated calcaneal fractures as malunion, subtalar distraction arthrodesis and lateral wall exostectomy will reduce disability of the disease.

Bosworth fracture-dislocation of ankle is very rare, occurred by eversion and external rotation force. It is known as irreducible fracture by closed method. Also, compartment syndrome after ankle fracture are exceedingly rare. There are only a few reported cases of compartment syndrome after ankle fracture and compartment syndrome are involved commonly deep posterior compartment. We present a case in which a patient had a Bosworth fracturedislocation of the ankle underwent open reduction with internal fixation and subsequently occurred an anterior compartment syndrome of the leg.

Purpose: This study was designed to investigate the usefulness of extensile lateral approach for accurate reduction and rigid internal fixation in comminuted intraarticular fractures of calcaneus. Materials and Methods: From October 2002 to May 2007, we managed 55 patients (62 cases) with open reduction and internal fixation using extensile lateral approach. Among these, 38 patients (43 cases) who underwent preoperative and postoperative CT scan were enrolled. All patients were evaluated over 24 months after surgery. Bohler angle and Gissane angle on plain X-ray, displacement and step-off of articular surface of calcaneus on CT scan were measured and we compared the difference between preoperative and postoperative value of them. Clinical results were assessed by using AOFAS Ankle-Hindfoot Scale. Results: The average Bohler angle was restored from $6.8^{\circ}$ to $23.5^{\circ}$ and Gissane angle was improved from $116.4^{\circ}$ to $113.5^{\circ}$ after operation. The average distance of displacement was restored from 4.2 mm to 1.4 mm and step-off of articular surface was recovered from 5.1 mm to 1.3 mm. Clinical results were excellent in 17 cases, good in 18 cases, fair in 3 cases, and poor in 5 cases. 10 cases developed postoperative complications such as skin necrosis, heel pain, limitation of motion of ankle and subtalar arthritis. Conclusion: The extensile lateral approach is valuable for the comminuted intraarticular fractures of calcaneus that enables accurate anatomical reduction and rigid internal fixation by providing direct exposure of subtalar joint.

Purpose: The diabetic foot lesions are intractable, and aggravation often leads to amputation. None or minor amputation group was treated debridement or toe amputation and major amputation group was treated Ray, Lisfranc, Chopart, Below Knee and Above Knee amputation. We investigate the risk factors for major limb amputations among patients with diabetic foot lesion. Materials and Methods: The subjects were 73 diabetic foot lesion patients (83 diabetic foot lesions) treated at our department from January 2006 to December 2010. Non or Minor amputation group of 44 cases were treated with debridement or toe amputation. Major amputation group of 39 cases were treated with Ray, Lisfranc, Chopart, below or above Knee amputation. We investigated socioeconomic factors, diabetes mellitus related factors and wound related factors and laboratory factors. Statistical analysis was done by Students t-test, Chi-square test, Mann-Whitney's U test. Results: In our analysis, wound size, wound classification (Wagner classification, Brodsky classification), white blood cell counts, polymorphoneuclear neutrophil percentage, hemoglobin, C-reactive protein and albumin were risk factors for major amputation (p<0.05). Conclusion: Low education level, nutritional condition, premorbid activity level and progressed wound condition were observed in major amputation group compared with non or minor amputation group. In the major amputation group, higher white blood cell count, C-reactive protein level and lower albumin level were observed. Together with maintenance of adequate nutritional condition, early detection of lesions and foot care for early treatment is important. Therefore, active investigation with full risk evaluation of vascular complication is also important.

The os intermetatarseum is a relatively uncommon bony anomaly of the foot. It is usually found between the bases of the first and second metatarsal bones and ossifies during adolescence. It is most commonly seen in radiographs as a separated ossicle, but it may arise as a spur from the base of the first or second metatarsal bone or from the medial cuneiform bone. It sometimes articulates with the base of the first or second metatarsal bone. We treated a painfull os intermetatarseum by excision, and had a good result after 13months follow-up.

Purpose: We analyse and report the result of transfibular ankle arthrodesis using lateral malleolar saving procedureversus lateral malleolar sacrificing procedure. Materials and Methods: Eighteen cases of transfibular ankle arthrodesis which were performed since 2001 were included. We devided them into lateral malleolar saving and lateral malleolar sacrificing groups. We reattached and fixed lateral malleolus in 10 cases and sacrificed malleolus for morcelized bone graft in 8 cases. We evaluated clinical results by AOFAS ankle-hindfoot score, visual analogue scale (VAS) and radiological results by union time. Complications and subjective satisfaction degrees were also recorded and compared between two groups. Results: Preoperative mean AOFAS score was 32 points (16~41) and VAS was 7.5 points (7~8) and they were changed into 68.6 points (61~77) and 2.8 points (2~4) postoperatively. There was no significant difference in clinical results between the two groups even though lateral malleolar saving group showed higher AOFAS score (69.4) than lateral malleolar sacrificing group (67.7). Duration of getting union was 11.3 weeks in lateral malleolar saving group and 10.6 weeks in lateral malleolar sacrificing group. There was no difference in subjective satisfaction level. There were one delayed union and one nonunion in lateral malleolar sacrificing group and one nonunion in lateral malleolar saving group. Conclusion: There was no difference in clinical and radiological results between lateral malleolar saving group and lateral malleolar sacrificing group of transfibular ankle arthrodesis. Therefore it may not necessary to sacrifice lateral malleolus for bone graft except very selective case for which heavy graft is needed.

Calcaneal fractures account for 2% of all fractures and approximately 60 to 70% of tarsal fractures. These fractures typically are the result of high-energy injury, such as a motor vehicle accident or a fall from a height. The potential for disabling malunion following intrarticular displaced calcaneal fracture is high, regardless of treatment. Fracture displacement typically results in loss of hindfoot height, varus and widening of the hindfoot, with possible subfibular impingement and irritation of the peroneal tendon and/or sural nerve. Frequently, subtalar joint develops posttraumatic arthritis. In symptomatic patients with calcaneal malunion, systemic evaluation is required to determine the source of pain. Nonsurgical treatment, such as activity and shoe modification, bracing, orthoses, and injection, is effective in many patients. Surgical treatment may involve simple ostectomy, subtalar arthrodesis with or without distraction, or corrective calcaneal osteotomy. A high rate of successful arthrodesis and of patient satisfaction has been reported with surgical manamgent.

Purpose: To evaluate the clinical results of anteroinferior tibiofibular ligament avulsion fracture accompanied ankle fractures treated with anatomical reduction and internal fixation. Materials and Methods: From January 2007 to April 2010, 30 cases with anteroinferior tibiofibular ligament avulsion fracture that treated with anatomical reduction and internal fixation were analyzed. The average follow-up period was 26 months (minimum 6 months). We have reviewed the bony union, complication and subjective satisfaction according to the fracture classification and method of internal fixation. Results: Among 30 cases, 28 cases were occurred in Lauge-Hansen classification supination-external rotation type, one case was fracture-dislocation and one case was Maisonneuve fracture. We have performed internal fixation with Mini screw in 11 cases, K-wire in 10 cases, repair in six cases and Mini screw & K-wire in three cases. In all cases bony union was completed. two cases in Mini screw, one case in K-wire, two cases in repair and one case in Mini screw & K-wire revealed LOM of ankle joint. Skin irritation and superficial peroneal nerve irritation happened in one case each. Other cases show good subjective satisfaction. Conclusion: Anteroinferior tibiofibular ligament avulsion fracture accompanied with ankle fracture is a good clinical outcome with internal fixation. So we should not miss out the anteroinferior tibiofibular ligament avulsion fracture in radiologic evaluation or operation room.

Purpose: To evaluate the effectiveness of intraoperative stress test for diagnosis of occult Lisfranc injury. Materials and Methods: Between April 2009 and October 2012, 21 patients with occult Lisfranc injuries underwent intraoperative stress test and internal fixation. There were 11 males and 10 females with an average age of 45.3 years (range, 23~79 years). Injuries were caused by traffic accident in 10 cases, indirect force (twisting injury) in 8 cases, and crush in 2 cases, falling from a height in 1 case. Unstable injuries on stress radiograph in occult injury of Lisfranc joint were treated by open reduction or closed reduction and fixation with cannulated screw or K-wire. Radiological evaluation was assessed according to preoperative and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base. Results: Assoicated injuries were 9 cases of metatarsal fractures, 6 cases of cuneiform fractures and 6 cases of both metatarsal and cuneiform fractures. Medial and middle column fixation was in 13 cases, and three columns fixation was in 8 cases. Initial diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 2.8 mm (1.3~4.7 mm) on AP radiograph and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 1.2 mm (0.5~2.4 mm) on AP radiograph. Conclusion: Even there is no sign of clear Lisfranc injury, it is necessary to pay attention and give evaluation on circumstances of occult Lisfranc injuries with metatarsal or cuneiform fractures. Intraoperative stress test is helpful to diagnose an occult Lisfranc injury. For unstable injuries on stress radiographs of occult Lisfranc joint injury, operative treatment with open or closed reduction and internal fixation is useful method.
