양보규,한성호,정선욱,이승림,하권익,이제오 대한슬관절학회 1999 대한슬관절학회지 Vol.11 No.2

Purpose : Up to now, there are several controversies in many aspects of osteochondritis dissecans. In this paper, we have intended to evaluate the frequent location and the etiology of the osteochondritis dissecans of the femoral condyles, and to assess the adequate modality of operative treatment and its results according to the modality. Materials and Methods : We reviewed retrospectively forty-four knees in forty patients. We analysed their clinical and radiological finding to take the incidence at both condyles and its etiology and to establish the modality of applied operative methods according to the status of the lesion. The performed operative methods were multiple drilling(1 case), fragment fixation(2 cases), curettage & multiple drilling(36 cases), osteochondral autotransplantation(5 cases). The majority of these operation was proceeded under arthroscopy. Its clinical results were assessed by Aichroth’s result grading system after an average follow-up of two-years and eleven months(range, one yer and two months to six years and one month). Results : Twenty one cases were medial femoral condylar lesions, and 23 cases were lateral. 91% patients had had the history of the definitive trauma(20 cases) or the minor repetitive trauma in their environments(20 cases). After operative treatment, seven knees had an excellent result; twenty-nine, a good result; six, a moderate result; and two, a poor result. Satisfactory result was 82%. Conclusion : On the basis of this review, we suggest that there is no difference in incidence between both femoral condyles, and that the trauma is seemed to play a major role as an etiologic factor. Majority of operated patients showed satisfactory results after application of our treatment modality.

양보규,이승림,안영준,임세혁,박상현 대한고관절학회 2016 Hip and Pelvis Vol.28 No.3

Fatigue fracture of the pelvis is the form of fracture due to repetitive micro-stress accumulation, can be affected by a number of factors such as patient’s nutritional status, biomechanics, social status and so on. Still there is no study about precise standard degree of external force that lead to stress fracture, but it may caused by compression force, traction force or complex force and others. Avulsion stress to ischial tuberosity or anterior superior iliac spine by attached muscle is known as the main factor for the avulsion fracture. This report will deal with 19 years old conscripted policeman who occurred ischial tuberosity avulsion fracture after training of 6-hour running for 5 days accompanying hip hyper-flexion motion. This reports aims to provide case study of stress fracture occurred after 5 days of exercise which is relatively short period who had no specific trauma history or pain.

Purpose : The goal of our study was to evaluate diagnosis and management of stress fracture in long bones using MRI findings. Material & Method: Between May 1995 to May 1999, 40 patients( 45 cases ) were confirmed to have a stress fracture by clinical and radiological findings. All patients were evaluated with clinical, X-ray, bone scan, and MRI findings. The patient was 21 years in average( range from 18 to 23 years ). All were males and soldiers. The evaluation was made by comparison of MRI and plain radiograph, and duration of symptom was evaluated with MRI grading by Fredericson et al. Result: The locations of stress fracture of long bones were tibia(n=25), fibula(n=14), and femur(n=6). MRI findings were bone marrow edema in 38(84.4%)cases, intramedullary low signal intensity band in 19(42.2%)cases which was continuous with cortex and cortical fracture line. Periosteal reaction was seen in 45(100%)cases and surrounding soft tissue edema in 20(44.4%)cases. Plain X-ray findings were peristeal reaction in 31( 68.9%)cases, medullary sclerosis in 10(22.2%)cases, and cortical fracture line in 8(17.8%) cases. Duration of symptom was longer in higher MRI grade. Conclusion: MRI was more useful in early diagnosis and differential diagnosis of stress fracture, showing various findings than plain radiograph. MRI grading was helpful in planning tlhe therapy of stress fracture.

Purpose: In this paper, we have intended to evaluate the types of fracture of the distal femur treated with anatomical bone plate, simple and user' s friendly apparatus and to assess their clinical results. Materials and Methods: We retrospectively reviewed 21 cases in 20 patients who were followed up over I year among the patients that had distal femoral fractures treated with anatomical bone plate. We analysed their fracture types in AO classification and assessed clinical results according to Neer system. The average duration of follow-up was 30 months(range, 14 months to 49 months). Results: Out of twenty-one cases, twelve were A type(A 1, 3 cases: A2, 4 cases: A3. 5 cases) and nine were C type(C1, 2 cases; C2, 4 cases; C3, 3 cases). But B type was none. Conclusions: This study demonstrate that the operation with anatomical bone plate is not only simple and user s friendly technique but also widely applicable method to treat A and C types of the distal femoral fractures.

Bilateral Necrotizing Fasciitis around the Hips Differentiated from Fournier Gangrene: A Case Report

양보규,이승림,이예현,김현세,남석우,안영준,김성완,양성욱,임세혁 대한고관절학회 2014 Hip and Pelvis Vol.26 No.4

As an emergency encountered in orthopedic practice requiring prompt diagnosis and aggressive treatment, necrotizing fasciitis around the hip must be discriminated from Fournier gangrene. The current case report describes a patient who suffered from bilateral type I necrotizing fasciitis around the hips, which was alleviated by prompt surgical debridement and intensive postoperative care.

소아 원위 경골 성장판 골절 Salter - Harris Type I & II 의 치료

양보규,한성호,이승림,유성환 대한골절학회 1999 대한골절학회지 Vol.12 No.4

It is known that the Salter-Harris type I and II fractures of the distal tibial epiphysis usually can be treated by conservative method. But according to Spiegel, unpredictable group (type II) fractures might have more complications than expected when treated by conservative method without accurate reduction. Eleven cases in type I or II fractures were treated at the National Police Hospital between March 1992 and March 1997. If more than 2mm displacement was present compared to contralateral side after closed reduction, open reduction and internal fixation method was done and in those all cases, periosteal interposition was found on the operative field that might interrupt anatomical reduction and cause late complications such as angular deformity.

양보규(Bo Kyu Yang),이승림(Seung Rim Yi),송중원(Joong Won Song) 대한정형외과학회 2013 대한정형외과학회지 Vol.48 No.5

종양성 석회증은 대사장애나 기저질환과 무관하게 석회성분의 침착을 일으키는 질환으로 원인은 명확하게 밝혀지지는 않았으나, 동양인에게는 드물게 발생하는 질환으로 알려져 있다. 저자들은 양측 고관절부와 둔부 및 천추부에 걸친 골반부에 다발성으로 발생한 거대 종괴를 주소로 방문하여 타 질환과의 감별을 위한 진단적 검사를 시행하고, 절제술로 치료한 거대 종양성 석회증을 문헌고찰과 함께 보고하고자 한다. Tumoral calcinosis is a very rare disease in which calcium deposit is accumulated on soft tissue around joints without specific metabolic disorder of calcium or predisposing illnesses. Its causes have not been revealed clearly, and the disease has been known to occur rarely among Asian patients. We report a case of a multiple giant tumoral calcinosis patient who complained of painful masses in the groin region as well as in both buttocks and sacral area. The patient was evaluated to differentiate with other causes and have been treated with surgical excision. We present this case with a review of literature.

양보규(Bo-Kyu Yang),김성완(Seong-Wan Kim),이승림(Seung-Rim Yi),안영준(Young-Jun Ahn),노정호(Jung-Ho Noh),노영학(Young-Hak Roh),이승원(Seung-Won Lee),제민수(Min-Soo Je),김석진(Seok-Jin Kim) 대한정형외과학회 2011 대한정형외과학회지 Vol.46 No.1

전방 골간 신경은 장 무지 굴근, 제 2수지의 심 수지 굴근과 방형회내근에 분포하며 감각 신경 섬유 없이 운동 신경 섬유로만 분포되어 있다. 몬테지아 골절에서 전방 골간 신경의 마비는 드물게 보고 되고 있으나, 이 중 불완전 마비는 거의 보고된 바가 없다. 저자는 몬테지아 골절의 합병증으로 장 무지 굴근 마비의 불완전 전방 골간 신경 마비가 발생한 환자 1예를 경험하였다. 요골 두에 대한 도수 정복을 시행한 후 수술적 치료로 척골 근위부 골절에 대해서 관혈적 정복 및 내고정을 시행하였으며 술 후 4개월에 장 무지 굴근 마비의 회복을 보였다. The anterior interosseous nerve innervates the flexor pollicis longus, the flexor digitorum profundus and the pronator quadratus. There are no sensory fibers from the anterior interosseous nerve leading to the skin. Paralysis of the anterior interosseous nerve that accompanies a Monteggia fracture has rarely been reported, and incomplete paralysis of the anterior interosseous nerve has almost not been reported. We experienced a patient with incomplete anterior interosseous nerve palsy involving the flexor pollicis longus as a complication of a Monteggia fracture. The paralysis of the flexor pollicis longus recovered 4 months after the surgery for the Monteggia fracture.
