Contact pressures in the flexed hip joint during lateral trochanteric loading

Contact pressures in the flexed hip joint during lateral trochanteric loading.

Acetabular fractures are an especially problematic outcome of motor vehicle side impacts. While fracture type has been correlated with impact direction and femoral orientation, actual contact pressures in the hip joint have not been quantified for lateral loading conditions. In the present study, we used pressure sensitive film to measure contact areas and pressures in seven hip joints from fou...

Contact pressures in the human hip joint.

The pressure distribution between the cartilaginous surfaces in the human hip joint was measured using pressure-sensitive film. Five cadaveric hip joints (aged between 58 and 87 years) were measured at three positions and loads, representing three instants in the stance phase of the walking cycle. The pressure distribution was not uniform, indicating that the cartilage did not, to any great ext...

In Vivo Hip Joint Loading during Post-Operative Physiotherapeutic Exercises

INTRODUCTION After hip surgery, it is the orthopedist's decision to allow full weight bearing to prevent complications or to prescribe partial weight bearing for bone ingrowth or fracture consolidation. While most loading conditions in the hip joint during activities of daily living are known, it remains unclear how demanding physiotherapeutic exercises are. Recommendations for clinical rehabil...

The incongruous hip joint: a loading study.

Hip incongruency was studied by load-displacement and casting methods. Twenty-five joints were loaded in 5 different positions of the walking cycle. Seventeen of them had a space at the apex in all positions, while 3 were congruent at low loads, and the remaining 5 had femoral heads smaller than their acetabula. No trends with age were apparent.
