OBJECTIVE The authors hypothesized that a patient who has posterior hip dislocation after total hip replacement does not have the same clinical manifestations of malposition as with a natural hip. The present study aimed to study clinical manifestation of hip dislocation after total hip arthroplasty. MATERIAL AND METHOD Thirty-five cases of posterior dislocation after total hip replacement we...

Reconstruction for concurrent infection of an ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is a challenge. We report a 2-stage reconstruction of a THA for chronic infection of both the THA and TKA with severe femoral bone loss secondary to interprosthetic fractures. The reconstruction involved using a custom-made, temporary, antibiotic-impregnated PROSTALAC spacer ...

OBJECTIVE The objective was to determine the effect of trunk focused neuromuscular training (TNMT) on hip and knee strength. The hypothesis was that TNMT would increase standing isokinetic hip abduction, but not knee flexion/extension, strength. METHODS 21 high-school female volleyball players (14 TMNT, mean age 15.4 (1.4) years, weight 170.5 (5.0) cm, height 64.1 (8.5) kg and 7 controls, mea...

BACKGROUND AND PURPOSE Stiff-knee gait is defined as reduced knee flexion during the swing phase. It is accompanied by frontal plane compensatory movements (eg, circumduction and hip hiking) typically thought to result from reduced toe clearance. As such, we examined if knee flexion assistance before foot-off would reduce exaggerated frontal plane movements in people with stiff-knee gait after ...

A simple method of maintaining hip abduction in the neonate with suspected congenital hip instability is described. Clinical observations and parental impressions are initially favourable.

BACKGROUND Several reports have suggested low bone mineral density (BMD) in patients with adolescent idiopathic scoliosis (AIS). We determined bone mineral status in patients with AIS to evaluate the effect of brace treatment on BMD. METHODS BMD was measured in 46 patients (mean age, 17.8 ± 4.9 years) with AIS (17 with brace and 29 without brace) by dual-energy X-ray absorptiometry scan and c...

Associations among hip motions, knee abduction and internal rotation motion during a drop vertical jump (DVJ), which increases the risk of anterior cruciate ligament injury, remain unclear. The pur...

The study objective is to test general- and sport-specific adaption during a single training on the Flexibility Trainer. device designed trigger residual muscle tone decreases of hip-joint muscles by providing (nearly) isokinetic resistance full range motion strength in adduction/abduction flexion/extension direction. Static hip flexion abduction as well kinematics double side kicks were analys...

QUESTION Do females with patellofemoral pain syndrome have decreased hip muscle strength compared with the unaffected side and with healthy controls? DESIGN A systematic review of observational studies published up to January 2008. PARTICIPANTS Females with patellofemoral pain syndrome and healthy controls. OUTCOME MEASURES Strength for at least one hip muscle group had to be included in ...
