Whether periacetabular osteotomy (PAO) improves hip microinstability in patients with symptomatic dysplasia remains poorly understood. To assess the femoral head translation static postural change, considered a potential indicator of microinstability, comparing dysplastic hips before and after PAO normal hips. Descriptive laboratory study. A total 26 (30 hips) underwent PAO, 18 healthy individuals (18 were eligible. Using 3-dimensional-to-2-dimensional registration technique, was quantified...
Background: Although most surgeons allow their patients to play golf after total hip arthroplasty (THA), the effect on implant during swing is still unclear. Purpose: To evaluate kinematics THA. Study Design: Descriptive laboratory study. Methods: Eleven hips in 9 who underwent primary THA were analyzed. All right-handed recreational golfers, and these 11 included 6 right 5 left hips. Periodic radiographic images of taken using a flat-panel x-ray detector. Movements joint components assessed...
Background: Although varus-tilted distal tibial deformity is an established risk factor for chronic lateral ankle instability (CLAI), no studies have reported whether this influences after arthroscopic ligament repair (ALLR) CLAI. Methods: A total of 57 ankles from patients who underwent ALLR CLAI were retrospectively analyzed. Tibial articular surface (TAS) angles measured on preoperative plain radiograph. After 12 months follow-up, recurrent and talar tilt stress radiograph evaluated as...
Hindfoot varus deformity is a known risk factor for chronic lateral ankle instability (CLAI). The impact of this on clinical results following arthroscopic ligament repair (ALLR) CLAI has not been studied.Sixty-three ankles from 62 patients who received ALLR were retrospectively examined. Preoperative plain radiographs used to measure tibial articular surface (TAS) angles, and long axial hindfoot alignment tibiocalcaneal angles (TCAs) pre- postoperatively. Results included ratings the...
The difference in vivo kinematics before and after total hip arthroplasty (THA) for the same subjects clearance between liner neck during squatting have been unclear. purpose of present study was to clarify (1) changes prosthetic hips osteoarthritis (2) extent liner-to-neck under weight-bearing conditions.This consisted 10 patients who underwent unilateral THA symptomatic osteoarthritis. Using a flat-panel X-ray detector, we obtained continuous radiographs squatting. We analyzed joint's...
Medial malleolar stress fractures are relatively uncommon. This report describes the successful treatment of nonunion a medial fracture due to chronic lateral ankle instability. A 13-year-old middle school student who belonged football club presented our clinic with left pain lasting over year. He had sprained his several times 6 years earlier. plain anteroposterior radiograph showed vertical line in malleolus involving epiphyseal plate, and computed tomography demonstrated seen on...
Although combined evaluation of hip joint kinematics and bone morphology is necessary for accurate assessment femoroacetabular impingement (FAI), there are no report which evaluated pincer-type FAI. The pre- postoperative a 46-year-old man, with FAI during squat were using image-matching techniques the rim-neck distance was measured. Preoperative simulation squatting also performed patient's models healthy subject's data to detect overlapping lesion between acetabulum femur....
