Heui-Chul Gwak,Jung-Han Kim 대한견주관절의학회 2016 대한견주관절학회지 Vol.19 No.2

Background: The first purpose of this study is to compare the clinical and radiological outcomes of surgical treatment for displaced midshaft clavicle fracture (Robinson type 2B1 vs. 2B2) with 3.5-mm low profile clavicular locking compression plate. The second purpose is to evaluate the difference of the results depending on the presence of accompanying injuries. Methods: Forty-nine patients who underwent an operation for the fractures were reviewed retrospectively. Fracture patterns were classified according to group 2B1 and 2B2 using Robinson’s classification. For radiological outcome, time to union after operation was evaluated and for clinical outcome, American Shoulder and Elbow Society (ASES) score, University of California in Los Angeles (UCLA) score, visual analogue scale (VAS), and range of motion (ROM) were evaluated from preoperative period to last follow-up period. Results: The mean time for union was not significantly different in the 2B1 group and 2B2 group (p=0.062). No statistically significant difference in ASES score, UCLA score, and VAS was observed between 2B1 and 2B2 (p=0.619, p=0.896, p=0.856, respectively). In ROM, significant higher mean forward flexion and abduction was observed in 2B2 (p=0.025, p=0.017, respectively) and there was no difference in external rotation and external rotation at shoulder 90o abduction position (p=0.130, p=0.180, respectively). There was no significant difference in clinical outcomes according to the accompanying injuries. Conclusions: There was no difference in clinical and radiological outcome between Robinson 2B1 and 2B2 type fracture after the operation. Accompanying injuries may not affect the clinical result of displaced midshaft clavicle fractures.

Purpose: The modified Broström repair (BR) technique has yielded good outcomes in patients with chronic ankle instability. This study compared clinical and radiological outcomes between two groups of patients who underwent modified BR or lateral ligament augmenta- tion using suture tapes (ST). Materials and Methods: Seventy-seven patients (ST group [n=47], BR group [n=30]; body mass index <26.61 kg/m2; mean age, 30.7±11.0 years [range, 17~39 years]; mean follow-up, 34.0±12.0 months [range, 24~59 months]) were retrospectively reviewed between January 2014 and July 2017. The Foot and Ankle Outcome Score (FAOS), American Orthopedic Foot and Ankle Score (AOFAS), Foot and Ankle Ability Measure (FAAM), visual analogue scale (VAS) score, and Sefton grading system were used for clinical assessment. The talar tilt angle and anterior talar translation were measured using the Telos stress device (Telos GmbH, Marburg, Germany) at 150 N for radiological evaluation. Results: FAOS, AOFAS, FAAM, and VAS scores improved in both groups at final follow-up (ST, 91.1±5.2, 93±2, 88.1±4.5, 1.5±0.7 vs. BR, 91.3±5.4, 93±3, 83.3±4.8, 1.2±0.7, respectively; p=0.854, 0.971, <0.001, 0.04, respectively). According to the FAOS, mean sports ac- tivity scores for the ST and BR groups at the final follow-up were 90.3±3.2 and 76.6±4.2, respectively, reflecting superior outcomes in the ST group (p<0.001). Sefton grading revealed satisfactory functional outcomes (ST, 91.5% vs. BR, 90.0%) . There was significant improve- ment in the talar tilt angle and anterior talar translation in both the ST and BR groups (7.6°±1.2°, 10.5±1.8 mm vs. 4.9°±1.1°, 7.9±1.5 mm, respectively; p<0.001). Conclusion: The ST group demonstrated comparable clinical but better improvement in mechanical stability and FAOS sports scores than the BR group.

목적 : 거골의 연골 병변에 대하여 관절정적 연골 성형술, 미세 골절술 및 자가 골연골 이식술을 시행 후 임상 결과 비교 및 결과에 영향을 미치는 인지를 평가하고자 하였다. 대상 및 방법 : 1998년 3월부터 2007년 12월까지 거골의 연골 병변으로 진단받은 환자들 중 관절경적 연골 성형술, 미세 골절술 또는 자가 골연골 이식술 시행 후 12개월 이상 추시가 가능했던 35명(36예)을 대상으로 하였다. 연골 성형술이 14예(13명), 미세 골절술이 12예(12명), 자가 골연골 이식술이 10예(10명)에서 시행되었다. 병변의 단계는 단순 방사선 산진 상 Berndt와 Harty 분류 및 Anderson 자기 공명 영상 분류를 사용하였다. 전 예에서 술 전 및 최종 추시에서 VAS score 및 AOFAS score를 측정하여 각각의 술식에 따른 임상적 결과를 평가 및 비교하였다. 병변의 위치, 크기, 단계 및 나이에 따른 임상적 결과를 평가하였다. 결과: 연골 병변 위치는 외측이 13예, 내측이 23예였으며 연골 병변의 평균 크기는 1.9 ㎠(1-4㎠)였다. 병변의 단계는 Berndt와 Harty 분류 및 Anderson 분류 2단계가 8예, 3단계가 21예, 4단계가 7예였다. 평균 추시관찰 기간은 15개월(12-30개월)이었으며, 전체 환자에서 VAS score 및 AOFAS score의 유의한 호전이 관찰되었으나, 각 술식 간의 의미있는 차이는 없었다. 병변 위치, 크기, 단계 및 나이에 따른 환자 군의 비교에서 유의한 차이는 나타나지 않았다. 결론: 관절경을 이용한 연골 성형술, 미세 골절술 및 자가 골연골 이식술 모두 거골의 연골 병변에서 유용한 치료 방법으로 사료되며, 병변 위치, 크기, 단계 및 나이에 따른 분류에서는 각 군별로 유의한 차이가 나나나지 않았다. Purpose: To compare clinical results and to evaluate the factors affecting the clinical results after performing arthroscopic chondroplasty, microfracture, and osteochondral autologus transplantation (OAT) due to a chondral defect of the talus. Materials and Methods: This study enrolled 35 patients (36 cases) diagnosed with a chondral defect of the talus and who could be followed over 12 months after arthroscopic chondroplasty, microfracture, or OAT between March 1998 and December 2007. The arthroscopic chondroplasties were carried out in 14 cases (13 patients), the microfractures were carried out in 12 cases (12 patients) and OAT was carried out in 10 cases (10 patients). The lesion staging used Berndt and Harty classification on simple radiographs and Anderson's classification on magnetic resonance images. Clinical results were evaluated and compared by measuring VAS and AOFAS scores at the time of operation, before the operation, and at the time of follow up Clinical evaluation included location, size, and stage of each lesion as well as the age of individual patient. Results: There were 13 medial and 23 lateral lesions. The average size of the chondral defects were 1.9 ㎠ (range 1-4 ㎠). According to the classification of Berndt and Harty and Anderson, there were 8 stage Ⅱ, 21 stage Ⅲ, and 7 stage Ⅳ cases. The average follow up period was 15 months (range: 12-30 months). VAS and AOFAS scores showed significant improvement in all treatment groups. However, clinical results according to the operative methods did not show any differences. Lesion size, stage and location, as well as of age of patient had no significant impact on clinical results. Conclusion: We concluded that all three procedures, arthroscopic chondroplasty, microtracture. and OAT, are useful for treating a chondral defect of talus. Location of lesion, size, stage and age of patient did not make a significant difference.

족부 족관절 분야에서의 관절경 술기

곽희철(Heui-Chul Gwak) 대한정형외과학회 2018 대한정형외과학회지 Vol.53 No.2

관절경을 이용한 유합술기는 관절경 기술의 발달로 인하여 점차 많이 시행되고 있고, 그에 따라 술자들의 경험도 증가하면서 그 사용 범위가 증가하고 있다. 관절경을 이용한 술식은 연부조직 손상의 최소화, 환자 위험 감소, 빠른 회복, 병원 재원 일수 감소 및 빠른 유합 시간 등의 많은 장점을 가진다. For the arthroscopic fusion procedure, the development of arthroscopic techniques of joint preparation for fusion have made arthroscopic ankle arthrodesis popular, and foot and ankle surgeons also have gained considerable experience in arthroscopic techniques. Arthroscopic techniques offer minimized soft tissue disruption, lower morbidity and mortality, faster recovery, and shorter hospital stay and time to fusion. In addition, they may reduce the risk of wound complications for patients with a poor soft tissue envelope or relevant co-morbidities.

목적: 제5 중족골 기저부 골절의 위치와 전위, 관절 침범, 분쇄 등의 특징이 조기 체중부하 치료의 결과에 어떤 영향을 미치는지 알아보고자 하였다. 대상 및 방법: 2013년 1월부터 2017년 7월까지 인제대학교 부산백병원에 내원하여 제5 중족골 기저부 제1, 2 구역 골절로 진단받은 총 34명의 34예를 대상으로 하였다. 평균 추시 기간은 13개월(6–15개월)이었다. 동 기간 동안 수술적 치료를 시행한 경우는 없었고 1명의 경우 추시 기간 중 이전 골절 부위와 다른 부위의 재골절로 제외되었으며 총 33예 모두 보존적 치료를 시행하였다. 족부의 전후면, 측면 및 경사 방사선 촬영 및 컴퓨터 단층 촬영을 시행하여 골절의 위치와 전위, 관절 침범, 분쇄의 정도를 평가하였다. 33명의 모든 환자에게 있어서 수상 직후부터 단하지 석고고정 혹은 탈착 가능한 부츠형 보조기를 선택하여 착용 후 통증이 허용되는 범위 내에서 부분적인 체중부하를 허용한 뒤 통증이 소실되면 일반 신발 또는 수술 후 신발을 착용 후 전 체중부하를 시행하게 하였다. 임상적 결과로 최종 추시 시에 American Orthopedic Foot and Ankle Society (AOFAS) score를 평가하였다. 외래 추시 시 족부의 단순 방사선 촬영을 하여 방사선적 골유합 시기와 업무로의 복귀 시기를 확인하였다. 결과: 총 33명의 환자가 본 연구에 참여하였고(남자 9명, 여자 24명), 환자들의 평균 나이는 48.7세(16–80세)였다. 제1 구역이 24명, 제2 구역이 9명이었고 전체 33명의 환자 중 22명에서 2 mm 이상의 골절 전위가 관찰되었고 관절 침범은 9명, 분쇄 골절은 5명에서 관찰되었다. 제1 구역에서 제2 구역에 비하여 통계적 의미 있는 업무로의 복귀를 보였고 최종 추시 시 AOFAS score는 우수한 결과를 보였고 통계적 차이는 없었다. 골절의 전위 정도, 관절 침범 여부, 분쇄 정도를 분류, 비교하였을 때 방사선적 유합 시기, 업무 복귀 시기에 있어 통계적 차이는 없었으며 모든 경우에 있어 최종 추시 시 만족할 만한 결과를 보였다. 결론: 제5 중족골 기저부 골절에서 골절의 위치, 전위, 관절 침범, 분쇄 여부에 관계없이 조기 체중부하를 허용하여도 만족할 만한 임상적 결과를 얻을 수 있다. 제5 중족골 기저부 골절에서 조기 체중부하하 보존적 치료는 우수한 임상 결과를 얻을 수 있는 좋은 치료 방법이라 생각된다. Purpose: To determine how the location, displacement, intra-articular involvement, comminution of a 5th metatarsal base fracture affect results of early weight-bearing treatment. Materials and Methods: From January 2013 to July 2017, 34 cases of 34 patients diagnosed with a fracture of the zone I and II 5th metatarsal base were enrolled. The mean follow-up period was 13 months (6–15 months). One patient was excluded as a refracture during the follow-up period, and 33 patients underwent conservative treatment. Anteroposterior, lateral, and simple oblique radiography and computed tomography of the foot were performed to evaluate the location and displacement of the fracture, the degree of joint involvement, and comminution. In all 33 patients, a short leg cast or boot brace was selected immediately after the injury, tolerable weight bearing was allowed. If the pain disappeared, full weight bearing was performed after wearing a plain shoe or postoperative shoe. As a clinical result, the American Orthopedic Foot and Ankle Society (AOFAS) score was evaluated at the final follow-up. During outpatient follow-up, a simple radiograph of the foot was taken to confirm the time of radiological bone union and return to work. Results: Nine males and 24 females, with an average age of 48.7 years, were enrolled in the study. Twenty-four patients had zone I fractures, and nine patients had zone II fractures. Twenty-two out of 33 patients had a fracture displacement of 2 mm or more. Nine and five patients had joint involvement and comminution, respectively. There was a statistically significant return to work from zone I to zone II. The AOFAS score was excellent at the final follow-up and there was no significant difference. When classifying and comparing the degree of fracture displacement, joint involvement, and comminution, there were no significant differences in the radiological union time and return to work. In all cases, satisfactory results were obtained at the final follow-up. Conclusion: Satisfactory clinical results can be obtained by allowing early weight-bearing regardless of the fracture location, displacement, joint involvement, or comminution in zone I and II 5th metatarsal base fractures.

중족통의 원인

곽희철,하동준,Gwak, Heui Chul,Ha, Dong Jun 대한족부족관절학회 2017 대한족부족관절학회지 Vol.21 No.3

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.

Osteochondroma, which is an osteocartilaginous exostosis, is essentially the most common primary bone tumor. These benign neoplasms are generally asymptomatic and have a relatively small potential for adverse effects. Calcaneal osteochondroma is rare, furthermore osteochondroma accompanying with gouty arthritis is very rare. Also, the subtalar joint is not a classic site of acute gout. In this report, we report the case of a patient who experienced an unusual calcaneal osteochondroma with undiagnosed gouty arthritis of the subtalar joint.
