이우천,강영훈,Lee, Woo-Chun,Kang, Yeong-Hun 대한족부족관절학회 2005 대한족부족관절학회지 Vol.9 No.2

Purpose: This study was performed to investigate the radiological characteristics of the degenerative arthritis of the ankle using the standing radiographs. Materials and Methods: From June 2001 to May 2005, 36 patients (56 ankles) who were treated for osteoarthritis of ankle were analysed. Angle of tibial shaft and tibial joint surface on AP view (TSA), angle of tibial joint surface on lateral view (TLS), tibial and medial malleolus angle (TMM) and talo-1st metatarsal angle were checked on standing radiograph. The patients with medial joint and total joint involvement were categorized into three stages according to the location of involvement. The degree of joint space narrowing was categorized into two groups. Results: There were no significant differences in TSA, TLS, TMM and talo-1st metatarsal angle with regard to the stage of arthritis. However, the difference between the less severe group and the severe group existed. Conclusion: Angular deformity was not correlated with stage, but correlated with severity. The deformity of distal tibial articular surface does not seem to be a cause of primary osteoartiritis, but rather a result from it.

김진구,강영훈,강경민,Kim, Jin-Goo,Kang, Yeong-Hun,Kang, Kyoung-Min 대한관절경학회 2000 대한관절경학회지 Vol.4 No.2

목적 : 저자들은 아킬레스 동종 이식건을 이용하여 관절경적 후방 십자 인대 재건술을 시행하였으며, 경골의 후방부 도달과 이식물의 통과 등에서 저자들이 개선한 시술방법의 유용성과 결과를 분석해 보고자 한다. 대상 및 방법 : 1997년 9월부터 1999년 9월까지 후방 십자 인대 파열로 진단받고 아킬레스 동종 이식건을 이용하여 재건술을 시행한 8명의 환자를 대상으로 하였으며, 추시 기간은 평균 21.7월 이었으며, 술전 Telos 스트레스 검사에서는 평균 14mm의 후방 불안정성을 보였다. 결과의 평가는 Telos 검사, Lysholm Knee Score 및 IKDC 판정기준을 이용하였다. 결과 : 술후 염증이나 신경 손상의 합병증은 없었으며, 술후 후방 불안정성은 Telos 스트레스 검사상 $0\~5mm$까지 6례, $6\~10mm$ 2례였다. 임상 평가결과 Lysholm knee score는 술전 평균 45점에서 술후 87점으로 향상을 보였으며 IKDC 판정상 A group이 2례, B group이 6례였다. 결론 : 아킬레스 동종 이식건을 이용한 후방 십자 인대 재건술은 충분한 이식건으로 안정성을 얻을 수 있고 공여부의 이환을 없앨 수 있으며 후격막 통과 도달법을 이용한 저자들의 개선된 술기는 수술시간의 단축과 정확한 경골 터널의 정립에 도움을 주었으나 안정성을 검증하기 위한 장기 추시가 필요하리라 생각한다. Purpose : We reviewed the results of arthroscopic posterior cruciate ligament reconstruction using Achilles tendon allograft, and the efficacy of the surgical technique using gradual tibial tunneling and posterior transseptal technique. Materials and Methods : From september 1997 to September 1999, 8 patients with complete PCL injury were treated by arthroscopic PCL reconstruction using Achilles tendon allograft. Mean follow-up period was 21.7 months. Mean preoperative posterior laxity was 14mm. The clinical outcome was assessed by Telos stress test, Lysholm knee score and IKDC score. Result : There was no complication such as infection and neurovascular injury. Posterior translation using Telos device was less than 5mm in 6 cases$(75\%)$, and between 6 to 10mm in 2 cases$(25\%)$. The mean Lysholm knee score was 45 preoperatively and improved to 87 postoperatively. In IKDC system, 2 of 8 patients were group A and 6 were group B. Conclusion : Arthroscopic PCL reconstruction using achilles tendon allograft and posterior transseptal technique shows reliable stability, short operative time and minimizing donor site morbidity but needs more long term follow-up.

The Effectiveness of Plantar Aponeurosis Release for the Limitation in First Metatarsophalangeal Joint Extension after Hallux Valgus Surgery

최홍준,김대욱,강영훈,박종호,손찬모,Choi, Hong-Joon,Kim, Dae-Wook,Kang, Yeong-Hun,Park, Jong-Ho,Son, Chan-Mo The Korean Foot and Ankle Society 2017 대한족부족관절학회지 Vol.21 No.2

Purpose: Stiffness in the first metatarsophalangeal joint after surgery for hallux valgus has been reported. The goal of this study was to test the efficacy of releasing plantar aponeurosis for improving the range of extension in the first metatarsophalangeal joint that was limited after hallux valgus surgery. Materials and Methods: Thirteen patients (1 man, 12 women [17 feet]; median age, 54.4 years; range, 44~69 years) with limited first metatarsophalangeal joint extension after hallux valgus surgery, who underwent an additional procedure of plantar aponeurosis release between March 2015 and August 2015, were included. Subsequently, the passive range of extension in the first metatarsophalangeal joint was evaluated via knee extension and flexion positions. Hallux valgus angle, inter-metatarsal angle, distal metatarsal articular angle, and talo-first metatarsal angle were measured on weightbearing dorsoplantar and lateral radiographs of the foot preoperatively. Results: The mean range of extension for the first metatarsophalangeal joint improved significantly, from $2.5^{\circ}$ to $40.9^{\circ}$ in the knee extension position (p<0.00). The mean extension range for the first metatarsophalangeal joint also improved, from $18.2^{\circ}$ to $43.2^{\circ}$ in the knee flexion position (p<0.00). In all patients, congruence of the first metatarsophalangeal joint was recovered. Conclusion: Plantar aponeurosis release is an effective additional procedure for improving the extension range of the first metatarsophalangeal joint after hallux valgus surgery.

금속판과 나사못 고정술을 이용한 장관골의 감염성 불유합의 치료

고한석 ( Han Suk Ko ),강영훈 ( Yeong Hun Kang ),김덕원 ( Deok Weon Kim ),하정구 ( Jeong Ku Ha ) 대한골절학회 2006 대한골절학회지 Vol.19 No.1

목적: 장관골의 감염성 불유합을 치료하는 데 있어서 금속판을 이용한 내고정술을 시행하였던 경우를 고찰하여 그 유용성을 평가하고자 하였다. 대상 및 방법: 1993년 3월부터 2004년 2월 까지 본원에서 장관골의 감염성 불유합으로 진단되어 금속판 내고정술과 동종 해면골 이식술을 시행 받았던 10예에 대하여 후향적 고찰을 하였다. 치료는 먼저 괴사조직의 철저한 변연 절제술과 세척후에 금속판을 이용한 고정술로 이루어졌고, 2례에서는 가교 금속판 고정법을 이용하기도 하였다. 동종 해면골 이식이 6예에 이루어졌으나, 창상의 상태에 따라 내고정 후 4주 뒤에 시행되기도 하였다. 결과: 10예 중 9예에서 방사선적 유합을 평균 6.8개월에 확인할 수 있었고, 그 이전에 감염증의 치료를 얻을 수 있었다. 결론: 금속판 내고정술은 감염성 불유합의 치료에 이용되는 견고한 고정 방법으로 유용한 방법이며, 삽입물이 감염증을 악화시킬 수 있다는 일반적 우려는 가교 금속판 고정술이나, 사전 철저한 변연 절제술, 해면골 이식등의 동반 술기로 극복할 수 있다고 생각된다. Purpose: To evaluate the usefulness of internal fixation with plate in treating infected nonunion of long bone. Materials and Methods: From March 1993 to February 2004, ten patients who underwent internal fixation with plate and cancellous bone graft on account of infected nonunion of long bone were retrospectively examined. The medical treatment were composed of thorough and adequate debridement of necrotic tissue, irrigation and plate fixation. Two patients were operated on with bridging plate method. Autologous cancellous bone graft was performed in 6 patients. In 2 cases, it was performed 4 weeks after internal fixation. Results: In 9 patients, radiographic union appeared on the average of 6.8 months and infections were cured before union occurred. Conclusion: Internal fixation with plate is a useful method for the solid fixation in the treatment of infected nonunion. The general concern was that the inserted hardware worsened the infection, which was overcomed with the operative techniques as bridging plate, debridement and cancellous bone graft.

김진구,강영훈 인제대학교 2000 仁濟醫學 Vol.21 No.2

Objectives: We reviewed the results of arthroscopic posterior cruciate ligament re construction using achilles tendon allograft, and the efficacy of the surgical technique using gradual tibial tunneling. Materials and Methods: From september 1997 to September 1999, 17 patients with complete PCL injury were treated by arthroscopic PCL reconstruction using Achilles tendon allograft. Mean follow-up period was 13.7 months. Mean preoperative posterior laxity was 17mm. The clinical outcome was assessed by Telos stress test, Lysholm knee score and IKDC score. Results: There were no complication such as infection and neurovascular injury. Posterior translation using Telos device was less than 5mm in 12 cases(70.6%), and between 6 to 10mm in 5 cases(29.4%). The mean Lysholm knee score was 41 preoperatively and improved to 84 postoperatively. In IKDC system, 3 of 17 patients were group A and 14 were group B. Conclusion: Arthroscopic PCL reconstruction using achilles tendon allograft shows reliable stability, short operative time and minimizing donor site morbidity but needs more long term follow-up.
