After single-bundle ACL reconstruction, three-dimensional computed tomography showed that the tibial tunnel-independent technique allows for the placement of the graft closer to the anatomical femoral tunnel position when compared with the traditional transtibial technique.

The purpose of this study was to investigate the validity of the supraspinatus test as a screening test for detecting torn rotator cuff and to determine what its valuable positive signs were. Both the empty-can test and full-can test were performed on 200 shoulders diagnosed by magnetic resonance imaging (MRI)-and in some cases, surgical findings-to have full-thickness or partial-thickness torn rotator cuff s, or no tear in the rotator cuff . During the maneuver, the presence of pain or weakness

Among patients that underwent total knee arthroplasty from June, 1990 to January, 1999, 61 cases (44 patients) that could be followed for more than 10 years were included in this study. The patients were divided into a patellar retention group and a patellar resurfacing group, and were compared with regard to their clinical and radiological outcomes. In patients undergoing primary TKA, a selective patellar resurfacing protocol was used. The indications for patellar retention were a small patella

The adjustable-length loop device provided comparable graft healing, implant-related failure, and clinical results with the fixed-length loop device, allowing adaptation of the graft to the different tunnel lengths. Therefore, it could be effectively used with an adjustment according to the femoral tunnel length.

We describe a rare case of sclerosing osteomyelitis of Garré in a 63-year-old woman with uncontrolled right thigh pain. She had suffered from lower back pain and radiating pain on the right lower leg for a year and 4 months and so had spine surgery 8 months ago. But the right thigh pain persisted, and the levels of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) remained abnormal. Right femur radiographs showed cortical thickening on the proximal femur. Magnetic resonance image

Background: Anatomic tunnel positioning is important in anterior cruciate ligament (ACL) reconstructive surgery. Recent studies have suggested the limitations of a traditional transtibial technique to place the ACL graft within the anatomic tunnel position of the ACL on the femur. The purpose of this study is to determine if the 2-incision tibial tunnel-independent technique can place femoral tunnel to native ACL center when compared with the transtibial technique, as the placement with the tibi

Purpose: The incidence of hip fracture associated with disability, pain and death increases in old age. The decreased bone mineral density, particularly due to osteoporosis, has been described as one of factors associated with the proximal femur fracture. Therefore, this study, measured the bone mineral density (BMD) of elderly patients with hip fractures to better understand the relationship between osteoporosis and proximal femur fractures. Materials and Methods: The bone densities of the femo

PURPOSE: The purpose was to identify the effect of intra-articular autogenous bone marrow injection on the healing of an acute posterior cruciate ligament (PCL) rupture in a rabbit model. The effect of autogenous bone marrow on the healing process was assessed serially by gross inspection, histologic examination, and immunohistochemical study of growth factors. METHODS: In both knee joints, the PCL was completely transected surgically near the femoral attachment site in 24 rabbits. Autogenous bo

Posterior malleolar fractures are usually caused by an abduction or external rotation injury. Indications for open reduction of the posterior malleolar fracture depend on its size and the amount of displacement. If the fragment of the posterior malleolus involves more than 25% to 30% of the articular surface, it should be treated by anatomical reduction and internal fixation. Authors analysed twenty-three patients of ankle fractures with the posterior malleolar fractures who were treated in Kang

A decreased bone mineral density, such as osteoporosis, has been considered a factor closely associated with proximal femur fractures. We studied the relationship between osteoporosis and proximal femur fractures. Dual energy radiograph absorptiometry was used to measure the bone mineral density of 121 patients with a femur neck fracture and 134 patients with an intertrochanteric fracture. The bone density of the femoral neck, Ward's triangle, and the trochanteric region were measured. Two hundr

목적: 노년층에서 통증, 장애 등을 초래하는 근위 대퇴부 골절은 점점 증가하고 있다. 골밀도의 감소, 골다공증은 이러한 근위 대퇴부 골절과연관된 인자 중 하나로 여겨지고 있다. 저자들은 근위 대퇴부 골절이 발생한 노년층에서 골밀도를 측정하여 골절과의 상관관계를 알아보았다. 대상 및 방법: 대퇴 경부 골절이 있는 60명, 전자간 골절이 있는 82명을 대상으로 DEXA를 이용한 골밀도를 측정하였다. 대퇴부의 경부와 전자부에서 측정하였으며, 본원 건강 검진 센터에서 골밀도 검사를 시행한 근위 대퇴골의 골절이 없었던 158명을 대조군으로 설정하였다. 이들을각각 성별 및 골절 유형에 따라 나눈 후 비교분석을 하였다. 결과: 근위 대퇴부 골절군에서 대조군 보다 골밀도가 유의하게 낮게 나타났다. 대퇴 전자간 골절의 골밀도는 대퇴 경부 골절의 골밀도 보다 낮았지만, 통계적으로 차이는 없었다. 대퇴 경부 골절과 전자간 골절군에서 각각 형태에 따른 골밀도 비교에서 유의한 차이는 없었다. 결론: 노년층
