Osteochondromas are benign bone tumors typically found in the metaphyseal region of long bones. These tumors are often asymptomatic and detected incidentally. However, their occurrence in atypical sites such as the talus can pose significant diagnostic and treatment challenges. This report describes a rare case of osteochondroma of the medial tubercle of the talus, which is an unprecedented location based on a review of relevant literature. A 28-year-old male presented with worsening medial ankle pain and limping. Imaging revealed a lesion consistent with osteochondroma contributing to medial ankle impingement syndrome. Uniquely, this case also featured a coinciding gout attack in the ankle joint. Surgical removal of the lesion resulted in significant symptom relief and functional improvement. This case underscores the need to consider rare diagnoses, such as talar osteochondroma, when presented with persistent medial ankle pain and highlights the potential presence of concurrent conditions, such as gout.

9 and 10 years old boys presented with pain and swelling without history of trauma around medial malleolar right and left ankle. The swelling was diffuse with tenderness on anterior aspect of medial malleolus. The X-rays revealed fragmented accessory ossification center of medial malleolus an symptomatic side. Traction apophysitis was diagnosed because MRI revealed multiple foci of hypointensity in T1 and T2 weighted images of symptomatic medial malleolus apophysis. Patient was treated in conservative treatment by short leg cast for three or four weeks with restriction of sports activity and improved symptoms.

Purpose: The purpose of this study is to evaluate the incidence and cause of reamputation with respect to the location of foot amputation. Materials and Methods: Eighty-six patients who received amputations below the ankle level from March 2002 to September 2012 with at least 1 year follow-up were enrolled in this study. We stratified the site of the initial amputation from first to fifth ray and into either the phalanx or metatarsal bone, and investigated the cause of reamputation. Results: The reamputation rate below the ankle level was 53.5%. It was highest (62.1%) in patients with first ray amputations without statistical significance. Rays were divided into two columns, first to third rays as the medial column and others as the lateral column, and reamputation was performed in 61.2% of patients with medial column amputation. Comparing the results between phalanx and metatarsal amputations, reamputation was performed in 62.1% of patients with metatarsal bone amputation. The rate of reamputation was statistically significant in both the medial column and metatarsal amputations. The most common reamputation site, in accordance to the initial site of amputation, was the adjacent ray (57.4%), which was without statistical significance. Moreover, the most common cause of reamputation was osteomyelitis and focal infection in all rays. Conclusion: This study showed that reamputation after amputation below the ankle level was relatively common with highest rate in medial column and metatarsal amputations. Hence, surgeons should be aware of the risk of reamputation and put more preventive effort during medial column and metatarsal amputations.

Purpose: The purpose of this study is to evaluate the clinical and radiologic results of using Acutrak screws for treating ankle medial malleolar fracture. Materials and Methods: We reviewed 38 cases of ankle medial malleolar fracture treated with Acutrak screws from February 2005 to May 2008. Results: In clinical result, there were 30 exellent cases, 7 good cases, 1 fair case. In radiologic result, there is no case with reduction loss. Average union time is 10.5 weeks. Conclusion: We conclude that Acutrak screw fixation is a useful method for ankle medial malleolar fracture, there are many advantages in accurate anatomical reduction, small incision, short operative time.

Osteochondral fracture is common in adolescent and usually occurs in the knee and ankle. Many authors have written concerning osteochondral fracture of the ankle joint, however, many of these pertain only to the talus. The author has found an osteochondral fracture of the articular surface of the medial malleolus within the ankle joint not previously described. We report a case of this lesion that was treated by arthroscopic osteochondral fragment removal.

Avulsion fracture of medial cuneiform by tibialis anterior tendon is quite rare. It has been reported about the avulsion fracture and surgical repair of tibialis anterior tendon rupture at distal insertion site of medial cuneiform in Korea. We report a case of right foot medial cuneiform avulsion fracture by tibialis anterior tendon after autobike accident and describe this case with a review of literature.

Purpose: Anatomic configuration of the ankle joint is useful information during various ankle procedures. This study was prospectively designed to investigate the sagittal inclination pattern of the ankle joint. Materials and Methods: Lateral standing ankle radiographs from one-hundred people (age: $17{\sim}68$, M:F=45:55) and magnetic resonance (MR) sagittal ankle images from twenty-four people (age: $16{\sim}65$, M:F=14:10) were studied. Post-traumatic, arthritic, or grossly deformed ankles at any reason were excluded. The posterior inclination angle (PIA) of the distal tibia was measured and compared between the lateral and the medial segment. Results: On plain radiographic data, the average PIA of the distal tibia was $6.14^{\circ}{\pm}3.56^{\circ}$ (range $0^{\circ}$ to $14^{\circ}$) in the lateral segment and $13.16^{\circ}{\pm}3.05^{\circ}$ (range $6^{\circ}$ to $22^{\circ}$) in the medial segment. On MR imaging data, the average PIA of the distal tibia was $5.08^{\circ}{\pm}4.26^{\circ}$ (range $1^{\circ}$ to $10^{\circ})$ in the lateral segment and $10.16^{\circ}{\pm}4.87^{\circ}$(range $5^{\circ}$ to $17^{\circ}$) in the medial segment. The PIA between two segments was significantly different. Conclusion: The sagittal configuration of the medial area ankle joint and the lateral area ankle joint has difference in the degree of posterior inclination and shape of curvature.

Accessory navicular is a congenital anomaly appearing in the secondary ossification center on the tuberosity of the navicular that may cause flatfoot. Bipartite medial cuneiform is another rare congenital anomaly occurring as two primary ossification centers in the medial cuneiform. The authors report a rare case of symptomatic bilateral accessory navicular with bipartite medial cuneiform and flatfoot deformity in a 19-year-old man with a review of the literature.

An extremely rare accessory bone of the foot located in the distal portion of the navicular that articulates with the medial cuneiform was observed. Os paracuneiforme is usually located medial to the medial cuneiform or the naviculocuneiform joint. Although os paracuneiforme is often referred to as an accessory bone around the foot, few cases of this type of accessory bone have been reported. This paper reports a patient with a painful Os paracuneiform who underwent surgical excision of the accessory bone.

For the adequate intraarticular exposure in medial talar dome lesions, medial malleolar osteotomy is necessary in some cases. Many operative techniques including transverse, oblique, inverted V-shape, crescentic and step-cut osteotomies of the medial malleolus have been described previously. But their techniques have several problems such as nonunion, rotation and limited access to lesions. So we introduce the new reverse chevron medial malleolar osteotomy which provides excellent access to lesions, good stability and a broad cancellous surface for rapid healing.
