Cementless total hip replacement (THR) is rapidly being accepted as the surgery for arthritic
diseases of the hip joint. The bone-ingrowth rate in porous-type cementless implants was …

[Purpose] The purpose of this study was to verify a method of spectral analysis of stride-to-stride
variability, and to apply this method to the analysis of the gait pattern of patients with …

[Purpose] We have proposed in a previous paper a novel indicator of smoothness using the
power spectrum entropy of acceleration time-series during movement. In this paper, we …

We propose a novel indicator for smoothness of movement, ie, the power spectrum entropy
of the acceleration time-series, and compare it with conventional indices of smoothness. For …

The concentration and molecular weight of hyaluronan (HA) in the synovial fluid of the hip joint
were determined in 13 patients (aged 62.8 ± 9.4 years) who had undergone prior total hip …

OBJECTIVE: To compare concentrations of joint biomarkers in synovial fluid (SF) between
idiopathic osteonecrosis of the femoral head (ION) and osteoarthritis (OA) of the hip joint. …

Necrosis of the transpositioned acetabulum after rotational acetabular osteotomy (RAO) is a
major complication characteristic of this procedure. This complication, although rare, has …

Fibrous tissue which regenerated on the acetabular arthroplasty surface was obtained from
a 52-year-old woman who underwent total hip replacement after cup arthroplasty. The …

Parameters of a logistic model were studied when the descriptive variables are not mutually
independent. For this purpose a generation algorithm of multiple test data with arbitrary …

We reviewed clinical results of 35 uncemented bipolar endoprosthesis implantations using a
Link ribbed hip prosthesis in 34 patients with an average follow-up of 4.0 years. The clinical …
