The purpose of this study was to determine patient-reported outcomes patients with mild moderate developmental dysplasia the hip (DDH) and femoroacetabular impingement (FAI) undergoing arthroscopy in treatment chondrolabral pathology. A total 28 a centre-edge angle between 15° 19° were identified from an institutional database. Their mean age 34 years (18 53), 12 female 16 male patients. All underwent labral concomitant correction FAI. There nine reoperations, two requiring revision...
We investigated the rate of conversion to total hip arthroplasty by twenty years and radiographic findings at a minimum after rotational acetabular osteotomy.Between June 1986 August 1991, we performed 172 osteotomies in 168 patients with dysplasia. Of those, ninety-three hips (ninety-one patients), including twenty-three pre-osteoarthritis, twenty-nine initial osteoarthritis, forty-one advanced had clinical available. The mean age was 32.4 (range, twelve forty-nine years). duration...
Objective To investigate the relationship between transient oxidative stress and development of osteonecrosis in a rat model. Methods A total 160 male Wistar rats (24 weeks old) were injected only once with pro-oxidant DL-buthionine-(S,R)-sulfoximine (BSO) (500 mg/kg given intraperitoneally) killed 12 hours (group A), 1 day B), 3 days C), 4 D), 5 E), 7 F), or 14 G) after administration (n = 20 per group). Twenty untreated used as control group N). Femurs examined histopathologically for...
The hip capsule has been identified as an important static stabilizer of the joint. Despite intrinsic bony stability socket, plays a key role in stability, particularly at extremes motion, and iliofemoral ligament is most extension external rotation. Patients who do not undergo capsular closure or plication may continue to complain pain dysfunction postoperatively, likely because microinstability muscle invagination into defect, high-resolution magnetic resonance imaging arthrography will...
The pathophysiology of rapidly destructive hip osteoarthritis (OA) the is still unclear. Also, there have been only few reports on initial stage disease. We report a case an initial-stage OA, documented by magnetic resonance imaging and intraoperative findings.A 77-year-old woman reported left pain without any antecedent trauma. Initial radiographs showed no obvious abnormality. After 4 months conservative therapy, progressive joint-space narrowing T1-weighted images revealed bone-marrow...
There is controversy about which more suitable for determining correct socket position in patients with severe bone deficiency of the acetabular roof because developmental dysplasia hip (DDH): anatomic centre rotation or a high centre. We evaluated relationship, 200 hips, between and presence Trendelenburg sign to determine upper limit cup from standpoint hip-abductor strength. Of 20 (10%) showed positive sign. were no statistically significant differences parameters (the rotation, femoral...
Objectives Favourable results for collarless polished tapered stems have been reported, and cement creep due to taper slip may be a contributing factor. However, the ideal thickness around remains unknown. We investigated influence of on stem subsidence creep. Methods cemented six (CPT) (two each small, medium large sizes) into composite femurs that had reamed with CPT rasp achieve various thicknesses mantle. Two or three tantalum balls were implanted in proximal femur. A cyclic loading test...
Objective Cement thickness of at least 2 mm is generally associated with more favorable results for the femoral component in cemented hip arthroplasty. However, French-designed stems have shown outcomes even thin cement mantle. The biomechanical behaviors a French stem, Charnley-Marcel-Kerboull (CMK) and were researched this study. Methods Six polished CMK implanted into composite femur, one million times dynamic loading tests performed. Stem subsidence compressive force bone-cement...
A tenosynovial giant cell tumor (T-GCT) is a benign synovial arising from the synovium, bursae, or tendon sheath. It can be intra- extra-articular and localized diffuse. Diffuse T-GCT considered as locally aggressive. Positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose computed (FDG PET/CT) widely used to differentiate malignant tumors detect distant metastasis. However, FDG PET/CT limited by false-positive findings. In this study, we present two cases of that developed in...
There is sometimes uncertainty concerning the correct socket position prior to total hip arthroplasty (THA). We conducted a study determine centre in Japanese women order define true anatomical of acetabulum. The involved 200 consecutive female patients whom contralateral joint was normal or prearthritic and who underwent unilateral THA. 'normal' group comprised 100 joints with no acetabular dysplasia, prearthritis Crowe type I dysplasia. length perpendicular line drawn under teardrop...
