Hip exercises are frequently prescribed following knee injury and subsequent surgery based on the assumption that hip weakness exists. No data, however, are available that support hip weakness following knee trauma or surgery. Therefore, the purpose of this study was to compare hip strength in patients after knee surgery. Twenty-seven patients who had undergone unilateral knee surgery were tested for hip flexor, extensor, abductor, and adductor isometric strength prior to initiation of rehabilitation. Multivariate analysis of variance revealed significant hip weakness in all four hip muscle groups of the surgical extremities (11.9-25.3%, p < or = 0.05) when compared with nonsurgical extremities. Both peak and endurance force were affected. The greatest percent difference between the surgical and nonsurgical extremity occurred for hip extension peak (25.3%) and endurance (22.6%) force development. We recommend assessment of hip strength following knee surgery and appropriate resistive exercises if weakness exists.

On account of the unusually rapid aging of the population, osteoporosis became the most important health problem for the elderly in Japan. There are approximately 10,000,000 patients with osteoporosis in Japan and almost 1,000,000 patients are in bedridden state. Hip fracture is the second most frequent cause for the bedridden state. Ministry of Health and Welfare funded several projects to assess the current status of osteoporosis and to prevent osteoporotic fracture. Japan osteoporosis Foundation founded in 1991 concentrations its effort on public education and research support on osteoporosis.

We report on the experience of five trauma receiving hospitals (four general hospitals and one spinal cord unit) in establishing a multicenter trauma registry (TR) for the purpose of data sharing. To ensure data comparability, all coders were oriented to standard data definitions and injury severity scaling. Coders and their physician sponsors met regularly to review data. Data presented for the four general hospitals from January through September 1992 address comparison of mortality rates, resource implications of isolated hip fractures, and the utility of knowing regional neurosurgical (NS) trauma volumes. Because of a statistically significant higher mortality rate at hospital 2, 7.2% versus 4.7% overall, mortality data were further characterized by patient age, mean ISS, and frequency of severe head injury. This still failed to explain the mortality difference. Hip fractures utilized 11,120 (26.3%) of the total 42,341 TR hospital days. Interhospital differences in median length of stay in this population suggest that greater resource efficiencies can be realized. Earlier questions about the value of including isolated hip fractures in the data set have been answered by understanding the resource implications of this population. Problems of NS coverage arising from a regional shortage of neurosurgeons can now be addressed with a better appreciation of the intraregional differences in NS volumes. Use of congruent data sets, combined with a collaborative approach, has stimulated the application of multicenter TR data to quality improvement, and utilization and regional planning issues.

Hip fracture is one of the most severe consequences of osteoporosis affecting aged women. However, abnormalities of bone turnover responsible for bone loss in this condition have not been clearly defined. To further evaluate the bone metabolic status of women sustaining hip fracture, we have prospectively measured serum osteocalcin as a marker of bone formation and urinary excretion of pyridinoline (Pyr) and deoxypyridinoline (D-pyr) cross-links as markers of bone collagen degradation in 174 independently living women (80 +/- 8 years) within a few hours after a hip fracture. Comparison was made with 77 age-matched controls (80 +/- 5 years) and 17 premenopausal women (39 +/- 3 years). In addition 15 of the patients were followed with daily measurements during the first postoperative week. At the time of admission osteocalcin was 20% lower in the fractured women compared to the elderly controls (7.6 +/- 3.8 vs. 9.5 +/- 4.5 ng/ml, P = 0.001). Pyr and D-pyr were 36% and 40% higher, respectively (P = 0.0001), than in elderly controls and 85% and 76% higher than in premenopausal controls (P = 0.0001). Serum osteocalcin did not correlate with the cortisol level measured at the same time (r = 0.03, ns), nor with serum albumin and creatinine. Serum osteocalcin remained unchanged within 18 hours after fracture, whereafter it progressively decreased until the third postoperative day. No correlation was noted between the excretion of pyridinoline cross-links and the time elapsed from fracture.(ABSTRACT TRUNCATED AT 250 WORDS)

Positions for nurses as coordinators and case managers have developed in response to demands for increased efficiency in the provision of hospital care. The Fractured Hip Management Programme in Western Sydney is one example of this development. The programme was introduced in response to mounting concern about the demands on hospital resources from elderly patients with hip fracture. A central feature of the programme is the pivotal role given to the nurse coordinator working within a multi-disciplinary team. This is not a new nursing role; rather it explicitly recognizes skills developed as part of the traditional nursing role. Evaluation of the programme found that patients received surgery sooner and spent less time in hospital, without adverse affects on outcome. The results show that recognition of the role of the nurse as patient advocate and care manager can lead to more cost-effective and higher-quality care.

Between 1978 and 1984, 183 hips in 154 patients with the uncemented Gerard double-cup arthroplasty were resurfaced. The clinical and radiographic results of the 106 original arthroplasties were reviewed after a median follow-up period of 98 months. Although many of these patients had clinically improved immediately, the Harris Hip score decreased significantly in most hips in subsequent years. No correlation was found between the clinical score and radiographic complications. Major revision surgery with removal of the double cup was performed in 54 of 183 patients, making the cumulative success rate after 132 months only 48%. Survival was significantly greater in patients younger than 50 years of age and in patients with a low body weight (Quetelet index less than 25). This high failure rate eliminates the Gerard double-cup arthroplasty, except possibly for the patient with a destructive inflammatory arthropathy for whom there are no other surgical alternatives.

Hip synovitis plays a part in many rheumatic diseases. In the young adult acute arthritis may be due to reaction to trauma, infection or gout. Although transient synovitis of the hip is a well-known phenomena in children the condition is not well-documented in adults. We present 10 young adults with idiopathic transient synovitis of hip who had attended the Soroka Medical Centre between 1986 and 1990.

We studied 1061 children with myelomeningocele, reviewing 3184 pelvic radiographs from 802 patients. Hip dislocation had occurred by the age of 11 years in 28% of children with a thoracic neurosegmental level, 30% of those with an L1/2 level, 36% of L3, 22% of L4, 7% of L5 and only 1% of those with sacral levels. Hip dislocation was not inevitable even when there was maximal muscle imbalance about the hip. The average hip flexion contracture in children aged 9 to 11 years was significantly greater in those with thoracic (22 degrees) and L1/2 (33 degrees) levels than in those with L4 (9 degrees), L5 (5 degrees) or sacral (4 degrees) levels. Our findings indicate that muscle imbalance is not a significant factor in the production of flexion deformity or dislocation of the hip; both are commonly seen in the absence of imbalance. The restoration of muscle balance should no longer be considered to be the principal aim of the management of the hip in children with myelomeningocele.

We made a randomised prospective comparison of the Dynamic Hip Screw and the Gamma locking nail for the internal fixation of 200 petrochanteric femoral fractures in elderly patients. There was less intraoperative blood loss and a lower rate of wound complications in the patients treated by the Gamma nail. They had, however, a high incidence of femoral shaft fracture which we relate in part to implant design. We do not recommend the use of the Gamma nail for these fractures.

The Normative Aging Study (NAS) recruited 2280 Boston area healthy males aged 21 to 80 in 1961 through 1970. Clinical exams have continued at 3- to 5-year intervals. Obesity was not an exclusion criterion. Stability in weight and body habitus among 867 adult participants in the NAS was evaluated at 5- and 15-year follow-ups. At study entry, age was linearly related to central adiposity [abdominal circumference (AC) and ratio of AC/Hip Breadth (HB)] throughout the entire age range (30 to 78 years) and linearly and quadratically related to weight (WT) and Body Mass Index (BMI) (kg/m2) with maximal values at age 50. Over 15 years, changes in adiposity were strongly related to age; the greatest increases were among those initially 30 to 44 years of age with decrements in several adiposity measures (BMI, AC) only among the oldest subjects (60+ at entry); significant quadratic effects of age for BMI (p < .001), WT (p < .02) and AC (p < .01). There were major secular differences; men born later were heavier and fatter at the same ages as men born earlier. Men who gained (> 1 BMI) were younger while men who lost (> 1 BMI) had greater initial central adiposity than others. Smoking cessation was independently associated with increments in both central and peripheral adiposity. Moderate alcohol intake was associated with lower gains in AC/HB ratios at 15 years compared with little or high consumption. In general, aging was associated with trends towards central adiposity which tended to plateau or decrease at the oldest ages.
