Purpose: To evaluate the clinical characteristics and the functional results of the osteochondral lesions of the talus (OLT) treated with arthroscopic osteochondroplasty. Materials and Methods: The study was based on 25 cases (25 feet) of osteochondral lesion of talus that were treated with arthroscopic osteochondroplasty from May 1997 to June 2005 with at least 1 year follow-up. Follow-up period was average 21.8 months. The average age was 37.2 years old. Male patients were 22 while female were 3. Postoperative evaluation was performed with American Orthopedic Foot and Ankle Society (AOFAS) Functional score, patient satisfaction and complications. Results: Ninety-two percent of patients had trauma history. Seventy-two percent of the lesions were located at the medial dome. As for the cartilage classification, 56% were fibrillation/fissure lesions while 44% were flap tears. Visual analogue scale (VAS) pain score improved from 6.8 points to 2.2 points, and AOFAS score improved from 71.3 points to 87.3 points. Eighty-eight percent of the patients were satisfied with the surgery and average period of returning to previous job was 6.5 weeks. Conclusion: We concluded that the arthroscopic osteochondroplasty is a viable surgical option for the osteochondral lesion of the talus.

Purpose: We are going to present a report from clinical and radiographic results of hallux valgus done only by soft-tissue procedure, when intermetatarsal joint is totally unfit under mild to moderate deformity. Materials and Methods: As a retrospective study, among all the patients who went under the surgery for hallux valgus, and of those who were possible to follow up,(excluding those whose intermetatarsal joint is fit) it was done over 28 cases (18 patients). the soft-tissue procedure was all done by Modified Mc Bride. Results: Hallux valgus angle and intermetatarsal angle each showed correction of $19.4^{\circ}$ and $5.2^{\circ}$, and from the final follow up, they were each decreased by $5.1^{\circ}$ and $1.5^{\circ}$. 21% (6case) were recurred, in one case, the intermetatarsal angle decreasing 120 and the other 5 case all decreased by $13^{\circ}$. Conclusion: when the intermetatarsal joint is unfit and there is no degenerative change, and, if the intermetatarsal angle is not large, moderate hallux valgus can show a good result, just by the distal soft-tissue procedure. a critical indication and a well through out preparation can reduce unneccessary surgeries.

Purpose: To evaluate the results of conservative treatment of zone I, II $5^{th}$ metatarsal base fracture. Materials and Methods: Between May 2004 and June 2010, a total of 58 patients of zone I, II $5^{th}$ metatarsal base fractures were included in this study. The mean length of follow-up was 13.5 months (12~36 months). All of the patients were treated with full-weight-bearing short leg cast immobilization for 4 weeks and wooden sole shoes for 4 weeks. The results were evaluated about the radiographic union, the midfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS), the tenderness on fracture site and other complications. Results: All patients were able to return to their prior levels of activity. The mean time for union as shown on radiographs was 45.5 days, and the mean midfoot scale of AOFAS was 99.7 points. There were no nonunions or refractures during the follow-up. Conclusion: The conservative treatment with full-weight-bearing short leg cast and wooden sole shoes seems to give good results for zone I, II $5^{th}$ metatarsal base fracture.

Purpose: The purpose of the present study was to compare and analyze the clinical outcomes of the percutaneous and open repair of acute Achilles tendon ruptures. Materials and Methods: We performed a retrospective study on 24 patients (group 1) managed with percutaneous repair, and 21 patients (group 2) managed with open repair for acute Achilles tendon rupture. The postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. Postoperative overall satisfaction and cosmetic satisfaction were also evaluated. Results: By Arner-Lindholm scale and AOFAS score, there was no difference between two groups (p<0.05). As for postoperative overall satisfaction, 5 cases were very satisfied, 16 cases were satisfied and 3 cases were fair in group 1. In group 2, 12 cases were very satisfied, 9 cases were satisfied. For postoperative cosmetic satisfaction, 13 cases were satisfied, 11 cases were fair in group 1. In group 2, 9 cases were very satisfied, 12 cases satisfied. In open repair group, a case of deep wound infection and three cases of skin necrosis were reported as complication. 2 cases of sural nerve injury were seen in percutaneous repair group and were recovered within 3 months. Conclusion: Percutaneous repair of acute Achilles tendon ruptures have high level of cosmetic satisfaction compared with open repair without any significant difference in clinical outcomes.

Purpose: Nonunion of intra-articular fractures of calcaneus is rarely reported complication. We present our experiences with 4 patients (5 cases) treated operatively for nonunion after intra-articular fracture of calcaneus. Materials and Methods: 4 patients (5 cases) with nonunion of intra-articular fracture of calcaneus after operative treatment were followed for 4 years (from 2002 to 2006). For assessment, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Visual Analogue Scale (VAS) were assessed for clinical outcome and the union of fracture site, the talocalcaneal height and the angle of talar declination were determined for radiologic outcome. Results: The mean talocalcaneal height was 6.94 cm (range, 5.9${\sim}$7.6 cm) preoperatively and 7.34 cm (range, 6.0${\sim}$8.3 cm) at last follow-up. The mean angle of talar declination was 5.68 degrees (range, 4.6${\sim}$8 degrees) preoperatively and 13.1 degrees (range, 5.7${\sim}$21 degrees) at last follow-up. The mean preoperative AOFAS score and VAS were 20.4 (range, 14${\sim}$36) and 4 (range, 3${\sim}$6), respectively. At last follow-up, these scores improved to a mean of 59.6 (range, 54${\sim}$68) and 3 (range, 2${\sim}$4), respectively. Unions of previous nonunion site of intra-articular fracture of calcaneus were achieved in all 4 patients (5 cases). Conclusion: The reconstructive procedure for nonunion of intra-articular fracture of calcaneus showed good results in terms of bone union, radiologic results and functional improvement than preoperative state. Because the plantar pain for the inferior angular formation in nonunion site may happen, we will pay attention to reduction of fragment.

Purpose: The purpose of this study is to find out the normal angles of forefoot for diagnosis of bunionette deformity in Korea. This would be helpful as it would provide a basic angular measurement of bunionette deformity that indicates the need for operation. Materials and Methods: Within a period of four months from January 2007 to April 2007. We have established 300 males and 600 feet without trauma history of foot. The source to image distance is 40 inches and erect weight bearing radiographs are obtained in anteroposterior and lateral projections. The significant angular measurements that define a bunionette deformity are the fourth-fifth intermetatarsal angle, the fifth metatarsophalangeal angle Results: The mean age was 21 years(19-22 years) old. The mean $4^{th}-5^{th}$ intermetatarsal angle was $9.4{\pm}4.7^{\circ}$, the mean $5^{th}$ metatarsophalangeal angle was $7.9{\pm}9.2^{\circ}$. Conclusion: We can consider over the $14.1^{\circ}$ on the $4^{th}-5^{th}$ intermetatarsal angle and over $17.1^{\circ}$ on the $5^{th}$ metatarsophalangeal angle as an operational indication.

Purpose: We tried to evaluate the usefulness of the arthroscopy in the operative treatment of intra-articular calcaneal fracture. Materials and Methods: Between March 2005 and May 2008, 9 patients with intra-articular calcaneal fractures（Tongue type or Sanders type IIC) were treated with arthroscopically assisted percutaneous reduction and screw fixation. American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), preoperative and postoperative Bohler's angle and the rate of complication were evaluated. Results: AOFAS score at postoperative 1 year was 88.2 (range, 71-92), and mean VAS score was 2.8 (range, 1-4). Bohler angle was improved from preoperative mean $16.2^{\circ}$ to postoperative mean $29.7^{\circ}$. There were no complications such as wound problem, infection or nerve injury. Conclusion: Subtalar arthroscopy provides precise view of posterior facet during the operation. Therefore, it can be a useful tool in treating intra-articular calcaneus fractures, especially tongue type and Sanders type IIC fractures.

Purpose: Tarsal coalition results from defects during the developmental stage and produes ankle pain and limitations in the range of motions. Its incidence has been reported to be 1%, but there has not been any reports with respect to Koreans. Therefore, we evaluated the prevalence of tarsal coalition in Koreans. Materials and Methods: Between 2005 and 2014, we analyzed a total of 733 cases of foot and ankle magnetic resonance imaging (MRI) in our hospital. There were 391 men and 342 women. All MRI readings were read by a radiologist in our hospital. We classified the coalitions in accordance with the histological and anatomical characteristics, and calculated the prevalence in each group. Moreover, we tried to determine the prevalence of tarsal coalitions in accordance with sex, age, and proportion of the symptomatic tarsal coalitions. Results: There were a total of 11 MRIs of tarsal coalition - 9 talocalcaneal coalitions, 1 calcaneocuboidal coalition, and 1 calcaneonavicular coalition. Nine tarsal coalitions were observed in men and 2 in women. Conclusion: Through this study, we found that the prevalence of tarsal coalition, including the asymptomatic patients, is similar to the previously known prevalence (1%). By getting more MRIs of the foot and ankle, we could better represent the prevalence of tarsal coalitions in Koreans.

This study was performed to evaluate the influences of the passive glenohumeral rotation on the scapulothoracic motion. We took anteroposterior radiograms of the right shoulders including the thoracic vertebrae with supine position in 10 normal male adults, at 0 degree abduction, 45 degrees abduction and 90 degrees abduction in scapular plane and in neutral rotation, maximal internal rotation and maximal external rotation in each abduction view. The scapulothoracic motion was measured as the distances between the vertical line drawn from the spinous process of the 7th cervical vertebra and the inferior and superior angles of the right scapula respectively. At 0 degree abduction, the distances were not changed in internal rotation relative to neutral rotation, but decreased significantly in external rotation, that is, the scapula shifts medially on external rotation. At 45 degrees abduction, the distances were increased significantly only in internal rotation, that is, the scapula shifts laterally on internal rotation. At 90 degrees abduction, the scapula rotated laterally on internal rotation and medially on external rotation. In conclusion, when a physician examines the rotation of the shoulder joint, he cannot exclude the scapulothoracic motion just by examining the patient with supine position. And we concluded that the rotatory movement of the shoulder is not solely contributed to the glenohumeral motion.
