We have operated total knee arthroplasty in a patient with bilateral congenital dislocation of the patella treated with a different method in each knee.
Diagnosis of lumbar foraminal stenosis remains difficult. Here, we report on a case in which bilateral lumbar foraminal stenosis was difficult to diagnose, and in which diffusion tensor imaging (DTI) was useful. The patient was a 52-year-old woman with low back pain and pain in both legs that was dominant on the right. Right lumbosacral nerve compression… (More)
BACKGROUND Total knee arthroplasty (TKA) is a common form of treatment to relieve pain and improve function in cases of rheumatoid arthritis (RA). Good clinical outcomes have been reported with a variety of TKA prostheses. The cementless Hi-Tech Knee II cruciate-retaining (CR)-type prosthesis, which has 6 fins at the anterior of the femoral component,… (More)
BACKGROUND Age-related sarcopenia may cause physical dysfunction. We investigated the involvement of sarcopenia in dropped head syndrome (DHS). METHODS Our study subjects were ten elderly women with idiopathic DHS (mean age 75.1 years, range 55-89). Twenty age- and sex-matched volunteers (mean age 73.0, range 58-83) served as controls. We used a… (More)
BACKGROUND Age-related sarcopenia can cause various forms of physical disabilities. We investigated how sarcopenia affects degenerative lumbar scoliosis (DLS) and lumbar spinal canal stenosis (LSCS). METHODS Subjects comprised 40 elderly women (mean age 74 years) with spinal disease whose chief complaints were low back pain and lower limb pain. They… (More)
STUDY DESIGN Retrospective observational study. PURPOSE To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) and foraminal stenosis (FS) using diffusion tensor imaging (DTI). OVERVIEW OF LITERATURE It is important in the selection of… (More)
