Ceramic femoral heads are now widely used in Total Hip Replacement (THR). Due to their high biocompatibility and low ductility, ceramic femoral heads are considered to be suitable for young and active patients. However, as in testing the mechanical stability of the femoral head, the conventional proof test (standard ISO 7206-10) has its limit of showing axisymmetric stress distribution on the contact surface, while non-uniformed stress distribution is expected after THR. Since non-uniformed stress distribution can result in the increased probability of ceramic femoral head fracture, it is considerable to evaluate the stress distribution in vivo-like conditions. Therefore, this study simulated the ceramic femoral heads under in vivo-like conditions using finite element method. The maximum stress decreased when increasing the size of the femoral head and stress distribution was concentrated on superior contact surface of the taper region.

This study was performed to evaluate the postoperative heating process according to lameness degree, swelling, and muscle atrophy after femoral head and neck ostectomy on Retriever dogs with hip dysplasia and hindleg lameness. Femoral head and neck ostectomy (FHO) was performed for the repair of hip dysplasia in 4 Retriever dogs (5 hips) referred in veterinary medical teaching hospital of college of veterinary medicine, Konkuk University. Age (Mean $\pm$ SD) of patients was 10.3 $\pm$ 3.0 months (range,7 to 16 months) and body weight (Mean $\pm$ SD) was 28.2 $\pm$ 3.4 kg (range, 25 to 34 kg). After FHO, all cases are treated with carprofen (2.2 mg/kg, PO bid, tapering at interval 1-2 weeks) and physical therapy including passive range-of-motion exercises. In all cases, lameness degree was showed V at the next day after surgery, IV at 5 to 7 days, II-III at 30 to 35 days, II at 60 days, and I at 105 to 114 days. These results suggested that femoral head and neck ostectomy was able to be performed on large breed dogs with hip dysplasia and hindleg lameness.

대퇴골두 무혈성괴사에 대해서는 수 많은 연구가 광범위하게 진행되어왔으나 아직 병인과 최선의 치료방법은 모르고 있는 실정이다. 앞으로 더 많은 연구와 분석이 이루어져서 새로운 정보가 추가된다면 이 질환으로 인한 유병율과 이환율을 줄일 수 있을 것이다.

대퇴골두의 연골 용해증은 관절 연골의 진행성 파괴로 인해, 이차적으로 발생하는 관절 간격의 감소와 강직이 특징이며, 이는 특발성으로 발생하는 경우가 가장 많고, 이차적 원인으로는 감염이나 외상 또는 장기간 고정 등이 거론되고 있다. 저자들은 45세 남자에서 화농성 고관절염 후 발생한 대퇴골두 연골 용해증을 경험하고 관절경하에서 치험하였기에 보고하는 바이다.

The purpose of this study was to test the hypothesis that even very small change of the cue direction in the treatment of the early osteonecrosis could affect the outcomes of operation. For this, the changes in stress transfer within the necrotic area of the femoral head were investigated under various directions and placements of the core utilizing finite element method. The loading of 3188N, which represents after-heel-strike, was imposed in cubic cosine pattern. All nodes on the most distal surface of the model were constrained in all directions. All materials included were assumed to have linear-elastic behavior. The result says that the critical stress, which causes collapse of the femoral head, was reduced when the core was oriented toward the posterior side of the femoral head regardless of location of the necrotic area. The same result was obtained either fibular bone grafting or cementation was adopted. As a consequence, the biomechanical study suggests that the core should be directed toward the loading point where the resultant force is applied to get more desirable treatment of the osteonecrosis of the femoral head in the early stage.

Purpose: In this study, subjects with femoral anterior glide type were examined to investigate the effects of femoral head anterior glide fixation during active straight leg raise on the strength of the hip flexor in a supine position. Methods: Fifteen subjects participated in this study. All subjects were classified through an evaluation form for femoral anterior glide type (FAGT). The strength of the hip flexor was measured during active straight leg raise test (ASLR test), and compared with and without femoral anterior glide fixation in a supine position. The fixation of the femoral head was achieved as per the therapist's manual guidelines. Paired t-test was applied to compare changes in the strength of the hip flexor according to fixation conditions. The level of statistical significance was set at α=0.05. Results: The strength of the hip flexor was lesser during the ASLR test with fixation compared to without fixation (p=0.007). Conclusion: The strength of the hip flexor decreases with fixation. Results of this study revealed a difference between hip flexor strength, with and without femoral anterior glide fixation during ASLR, in subjects with femoral anterior glide type.

Legg-Calve-Perthes diseases were diagnosed in 2 dogs showing signs of lameness. In radiographs, the abnormal size and shape was due to the collapse of the left capital bone and enlarged femoral neck was seen at case I. The completely deformed left femoral head resulted from the earlier collapse of the osteolytic bone of the caput femoris at case II. In treatment, femoral head ezcision was performed in one dog.

대퇴골두 무혈성괴사는 혈류장애로 인해 대퇴골두의 골세포 괴사가 나타나는 것으로 여러 원인 중 방사선치료도 하나의 원인으로 알려져 있으나 발병률에 대해서는 보고된 바 없는 상태이다. 저자들은 삼성서울병원에서 전골반 방사선치료를 받은 자궁암환자 577명 중 2명의 환자에서 대퇴골두 무혈성괴사를 경험하였다. 2예 모두 전형적인 방사선학적 소견을 보였다. 골반 방사선치료 후 발생하는 대퇴골두 무혈성괴사는 매우 드물게 나타나지만 방사선 조사 범위에 국한된 특징적인 영상의학적 소견을 보이므로 진단에 유념해야 하겠다.
