To investigate the effects of total knee arthroplasty on joint proprioception, the absolute angular error of the knee in 38 consecutive patients before and after total knee arthroplasty for osteoarthritis and in 23 age-matched control subjects were examined. Varus and valgus laxity of the knee and muscle strengths of the thigh were measured using(More)
We investigated lordotic alignment and posterior migration of the spinal cord following en bloc open-door laminoplasty for cervical myelopathy. Fifty-five patients (32 men and 23 women) were studied, with an average follow-up of 2.4 years. Radiological examination included evaluation of lordosis of the cervical spine and spinal cord, degree of enlargement(More)
OBJECTIVE To investigate changes in axonal flow after nerve root compression by using immunohistochemical techniques to detect calcitonin gene-related peptide (CGRP), which is thought to be involved in pain sensation. DESIGN Experimental, controlled study. SETTING University medical school in Japan. ANIMALS Forty adult mongrel dogs (weight, 7-15kg).(More)
STUDY DESIGN A histologic and histochemical study was performed both in the autopsy of a human patient with cervical spinal cord compression caused by ossification of the posterior longitudinal ligament and in a tiptoe-walking Yoshimura mouse model of progressive cervical cord compression. OBJECTIVES To clarify the mechanism of destructive pathologic(More)
STUDY DESIGN This study examined the effect of lumbar nerve root compression on nociceptive neuropeptides in the axonal flow using an in vivo model. OBJECTIVES The aim was to investigate changes in axonal flow after nerve root compression by using immunohistochemical techniques to detect substance P (SP) and somatostatin (SOM), which is thought to be(More)
Mesenchymal stem cells (MSC) derived from bone marrow can potentially reduce the acute inflammatory response in spinal cord injury (SCI) and thus promote functional recovery. However, the precise mechanisms through which transplanted MSC attenuate inflammation after SCI are still unclear. The present study was designed to investigate the effects of MSC(More)
INTRODUCTION Mesenchymal stem cells (MSCs) can differentiate into various connective tissue cells. Several techniques have been used for the clinical application of MSCs in articular cartilage repair; however, there are many issues associated with the selection of the scaffold material, including its ability to support cell viability and differentiation and(More)
OBJECTIVE To determine the effects of lateral wedged insoles on knee kinetics and kinematics during walking, according to radiographic severity of medial compartment knee osteoarthritis (OA). DESIGN A prospective case control study of patients with medial compartment OA of the knee. SETTING Gait analysis laboratory in a university hospital. (More)
STUDY DESIGN This study was aimed at investigating changes in the dorsal horn of the lumbar cord induced by mechanical compression using an in vivo model. OBJECTIVE To determine the effect of axonal flow disturbance in the dorsal horns induced by nerve root compression. SUMMARY OF BACKGROUND DATA Few studies have looked at changes of synapses within the(More)
Hematomas following surgery or trauma usually resolve without complications. In some instances, for reasons that are not completely understood, hematoma formation is followed by slow expansion of the mass. The large fluid collection is surrounded by a pseudocapsule and fibrous tissue, and present months or years after the original insult, as chronic(More)
