Temporary External Fixation Can Stabilize Hip Transposition Arthroplasty After Resection of Malignant Periacetabular Bone Tumors.

Background: The choice of reconstructive procedure to restore limb function is challenging after internal hemipelvectomy. Hip transposition arthroplasty, also known as resection arthroplasty, removes a malignant or aggressive tumor of the pelvis and acetabulum after which the remaining femoral head is moved proximally to the lateral surface side of the sacrum or the underside of the resected ilium after internal hemipelvectomy. It may provide reasonable functional results and have some advantages such as lowering the risk of an infected implant compared with other reconstructions because no foreign implants are used.

Difference between the Right and Left Phrenic Nerve Conduction Times, Latency, and Amplitude.

We studied phrenic nerve conduction times in 90 phrenic nerves of 45 normal subjects. The phrenic nerve was stimulated at the posterior border of the sternomastoid muscle in the supraclavicular fossa, just above the clavicle, with bipolar surface electrodes. For recording, positive and negative electrodes were placed on the xiphoid process and at the eighth intercostal bone-cartilage transition, respectively.

Preoperative time required for the timed "up and go" test in women with hip osteoarthritis could predict a deep venous thrombosis complication after total hip arthroplasty.

We examined whether the preoperative time required for the Timed "Up and Go" (TUG) test could predict the risk for deep venous thrombosis (DVT) in patients with hip osteoarthritis after total hip arthroplasty (THA). Eighteen patients with DVT diagnosed by venography were selected, and 18 without DVT of the same age and sex and with the same operated side as the DVT group were selected as a control group. We evaluated the 5 preoperative factors that might affect the occurrence of DVT complications, as follows:disease duration, body mass index, serum total cholesterol, subjective pain evaluated by the visual analog scale, and TUG.

The effect of service dogs on the improvement of health-related quality of life.

To assess the effects of service dogs on health-related quality of life (HRQOL), we conducted a survey of 10 service dog owners using SF-36v2 (Medical Outcomes Study 36 Item Short-Form Health Survey Version 2.0) and compared it with a matched control group of people with physical disabilities who did not have service dogs but were eligible for one. The scores for mental health and role emotional of service dog owners were relatively high, and their mental component summary was higher than the general population norm.

[Musculoskeletal rehabilitation and bone. Locomotion system disorder with aging and rehabilitation].

Muscle weakness and fall of ability for balance occur as becoming old. It is the worst results to fall down, and to break their bones. It is easy to have fracture elder people so that there is osteoporosis, and therefore they cannot walk, and become bedridden For a purpose to prevent that a senior citizen becomes a care state required by fall, we define "the state that fall of ability for balance and locomotive system result from aging and shut ourselves up, and a fall risk rose" as Musculoskeletal Ambulation Disability Syndrome (MADS) .

Effect of vision on postural sway in anterior cruciate ligament injured knees.

Recent clinical studies have investigated postural sway characteristics in anterior cruciate ligament (ACL)-deficient knees, but the relative contributions of vision and ACL remain unclear. In the current study, we measured and compared postural sway during one-leg standing with eyes open and closed to assess the difference between legs with and without ACL injury, and we discuss the contribution of the ligament relative to vision and to postural sway in patients. We examined 32 patients (17 males, 15 females) with ACL injury before surgery from March 2001 through January 2004.

Relationship between postural balance and knee and toe muscle power in young women.

Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus length per environmental area, environmental area, rectangle area, root mean square area, and the ratio of sway with eyes closed to sway with eyes open.

Talonavicular joint abnormalities and walking ability of patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) is often associated with deformities of the feet, and foot pain often arises in the talonavicular joint of patients with RA. The object of this study was to assess the relationship between magnetic resonance imaging (MRI) findings of the talonavicular joint and walking ability.

Three-dimensional gait analysis of adults with hip dysplasia after rotational acetabular osteotomy.

Dysplasia of the hip, the most common cause of secondary coxarthrosis, has a relatively high prevalence in Japan. Rotational acetabular osteotomy (RAO) is an interventional strategy that seeks to reduce the abnormal amount of high stress concentration in the acetabulum and thereby to prevent the development of coxarthrosis. Long-term clinical results have been reported, but functional evaluations of the gait before and after RAO are underreported.

Oxygen dynamics at paraspinal muscles during exertion using near-infrared spectroscopy in patients with degenerative lumbar scoliosis.

Oxygen dynamics were measured in both sides of the paraspinal muscles of patients with degenerative lumbar scoliosis. The objective was to investigate the extent of stress by measuring the changes in oxygenation and blood flow volume using near-infrared spectroscopy. There were 44 patients with degenerative lumbar scoliosis (7 men, 37 women) and 11 controls with no scoliosis (2 men, 9 women).

Electrophysiological assessment of the carpal tunnel syndrome in hemodialysis patients: formula for predicting surgical results.

Nerve conduction studies performed between 1994 and 1996 on the median nerves of 204 hands of 113 patients [20 patients in hemodialysis (HD) with diabetic nephropathy, 27 without diabetes mellitus in HD for 10 years or more, 18 without diabetes mellitus in HD for less than 10 years, and 48 with diabetes mellitus not undergoing HD] were reviewed retrospectively to develop a discriminating tool that would better inform treatment selection for patients with carpal tunnel syndrome (CTS) in HD. Scatter diagrams were drawn from the results of this study, and a regression formula was obtained. Among the long-term HD patients without diabetic nephropathy, distal motor latency (DML) tended to increase without a significant concomitant reduction in motor nerve conduction velocity (MCV) in the forearm.

Carpal tunnel syndrome grading system in rheumatoid arthritis.

The grading system of Hashizume and Hirooka for carpal tunnel syndrome (CTS) was modified to refine the system for surgical treatment selection for specific subsets of CTS in patients with rheumatoid arthritis (RA). The grading system uses clinical signs and symptoms of CTS, including pain indications, to identify surgical subsets of patients to facilitate treatment selection. Retrospective analysis of the system included radiographic and electromyographic findings.
