Objectives : This study was conducted to understand 4 groups in tentatively named "muscle coordinative manipulation" by Korean medicine. Methods : We researched some articles on meridian-muscle theory and muscle's action that are classified into 4 groups in muscle coordinative manipulation. Results : The outcome of examining the hypothesis is as follows: 1. The 1st hypothesis : 'Elevated shoulder' group mainly consists of muscles that are involved with shoulder elevation, abduction and external rotation. 'Lowered shoulder' group is mainly composed of muscles that acts of shoulder depression, adduction and internal rotation. 'Elevated pelvis' & 'Lowered pelvis' groups didn't show significant features by the movement of the hips. 2. The 2nd hypothesis : Most of muscles in 'elevated & lowered shoulder' groups are classified into 'hand taiyang' meridian-muscle. Most of muscles in 'elevated pelvis' group are included in 'foot jueyin' meridian-muscle. Most of muscles in 'lowered pelvis' group are classified into 'foot taiyang & foot yangming' meridian-muscle. Conclusions : There is no significant classification in muscles that comprise 4 groups in muscle coordinative manipulation when it comes to meridian-muscle theory and muscle function. More studies on chain reaction of muscle and subsequent analysis in Korean medicine are needed.

Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. Various terms are used to describe this clinical entity, including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Several treatment options are available; the choice of treatment is based on the type and size of the defect and the treating clinician's preference. Arthroscopic microfracture (a bone marrow stimulation technique) is a common and effective surgical strategy in patients with small lesions or in those in whom non-operative treatment has failed. This study had the following aims: 1) to review the historical background, etiology, and classification systems of OLT; 2) to describe a systematic approach to arthroscopic bone marrow stimulation for OLT; and 3) to determine the characteristics that are useful for assessing osteochondral lesions, including age, size, type (chondral, subchondral, cystic), stability, displacement, location, and containment of the lesion.

Purpose: This study was performed to analyze the characteristics of calcaneocuboid joint involvement in intraarticular calcaneal fractures. Materials and Methods: Total number of 92 patients (111 cases) who underwent operation for intraarticular calcaneal fractures between Jan. 2000 and Oct. 2005 were included in this study. The preoperative computed tomographs of the subjects were retrospectively reviewed to analyze calcaneocuboid joint involvement. Results: It was revealed that 63 cases (56.8%) involved calcaneocuboid joint; 29cases (46.0%) showed type 1 (undisplaced or minimally displaced type, articular gap ${\le}1\;mm$), 16 cases (25.4%) exhibited type 2 (moderately displaced type, articular gap ${\ge}2\;mm$), 7 cases (11.1%) were included in type 3 (comminuted type) and 11 cases (17.5%) belonged to type 4 (fracture and dislocation). 48 out of 63 cases belonged to Sanders classification II and III that involved calcaneocuboid joint and included 25 cases (52.1%) of type 1 and 14 cases (29.2%) of type 2. Among 15 out of 63 cases included in Sanders classification IV, 4 (26.7%) showed type 1 and 6 (40.0%) belonged to type 4. According to our results, Sanders classification allowed to predict pattern of the involvement of calcaneocuboid joint (P<0.05). However, there was no statistically significant relationship between degree of posterior facet joint injuries and calcaneocuboid joint involvement (P>0.05). Conclusion: Calcaneocuboid joint involvement in intraarticular calcaneal fractures was common and more than half showed severe injuries. We concluded that further studies on the involvement of calcaneocuboid joint should be performed prior to surgical treatment of intraarticular calcaneal fractures.

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.

Background: The Pediatric Balance Scale (PBS) was developed to assess of balance ability in children with balance problem. The PBS was translated into Korean and its reliability had been studied. However, it had need to be verified using psychometric characteristics including item fit and rating scale. Objects: The purpose of this study was to investigate the item fit, item difficulty, and rating scale of the Korean version of PBS using Rasch analysis. Methods: In total, 40 children with cerebral palsy (CP) (boy=17, girl=23) who were diagnosed with level 1 or 2 according to the Gross Motor Function Classification System participated in this study. The PBS was performed, and was verified regarding the item fit, item difficulty, rating scale, and separation index and reliability using Rasch analysis. Results: In this study, the 'transfer', and 'turning to look behind left and right shoulders while standing still' item showed misfit statistics. in total 40 children with CP. Also, 'transfer', 'standing unsupported with feet together' and 'standing with one foot in front' items showed misfit statistics in diplegia CP group. Regardless of the classification of CP, the most difficult item was 'standing on one foot', whereas the easiest item was 'sitting with back unsupported and feet supported on the floor'. The 4 rating scale categories of PBS were acceptable with all criteria. Both item and person separation indices and reliability showed acceptable values. Conclusion: The PBS has been proven reliable, valid and is an appropriate tool, but it needs to modify the items of PBS according to CP classification.

Purpose: To analyze the results of conservative or surgical treatment after computed tomograhy(CT) classification in intraarticular calcaneal fractures. Materials and methods: From January 1996 to May 1999, we prospectively analyze 23 cases of intraarticular calcaneal fractures who were treated conservatively or operated by open reduction and internal fixation by extensive L-shaped lateral approach after CT classification. Results: A functional scoring system of 0-100 points which was based upon the responses to AOFAS Ankle-Hindfoot Scale for the operative group was at 82.8, compared with 73.2 for the non-operative group, and these were meaningful statistically(P<0.05). Of type I fracture, in the operative group there were 2 excellent results and in the non-operative group there were 2 excellent results, 1 good result. or type II fractures, in the operative group there were 2 excellent results, 3 good results, 1 fair result and in the non-operative group there were 1 good result, 1 fair result, 2 poor results. Of type III fractures, in the operative group there were 2 fair results, 2 poor results and in the non-operative group there were 1 fair result, 3 poor results. Bohler angles of subtalar joint were changed from initial average $13.3^{\circ}$ to postoperative average $20.9^{\circ}$ for the operative group compared with from initial average $15.5^{\circ}$ to follow-up average $14.8^{\circ}$ of the non-operative group(P<0.01). Conclusions: Computed tomography in the evaluation of intraarticular calcaneal fractures is effective tool. We believed that open reduction and internal fixation in all Crosby & Fitzgibbons type II and according to degrees of comminution reducible type III for the intraarticular calcaneal fractures is more effective method than conservative treatment.

Metatarsalgia is one of the most common causes of patients complaining of pain in their feet. This pain is the plantar forefoot, including the second to fourth metatarsal heads and arises from either mechanical or iatrogenic causes. On the other hand, it is frequently accompanied by a deformity of the toes as well as of the first and fifth rays. The pain has a variety of causes, and sometimes the cause is difficult to distinguish. The variability of possible causative factors necessitates an individualized approach to treatment. To determine these causes, this paper presents an overview of the gait mechanics, plantar pressure, and the classification according to the etiology.

The bunionette, or a 'tailor's bunion', is a lateral bony prominence of the fifth metatarsal head. A bony deformity itself rarely causes symptom but if a painful inflammation of the overlying soft tissue is accompanied, it needs treatment. Conservative care using a shoe modification, padding, or orthosis is effective in most cases. Surgical management is indicated when the conservative methods have failed to improve symptoms, and the techniques include exostectomy, metatarsal osteotomies (distal, diaphyseal, or proximal), metatarsal head resection or fifth ray resection. We reviewed the etiology, clinical features, radiographic classification, nonoperative and operative treatments of the bunionette.

Syndesmotic injury can either be isolated or associated with bony or ligamentous ankle injury. When it is not associated with an ankle fracture, it may not be easy to diagnose, especially when there is no franck diastasis on a plain radiograph. Without proper treatment, syndesmotic injury can lead to chronic pain due to impingement of scar tissues and instability. It may further lead to ankle arthritis. Early diagnosis with appropriate management is a prerequisite to avoid these problems. Herein, we review and discuss the mechanism of injury, classification, diagnosis, and treatment of isolated syndesmotic injury.
