Pelvic ring injury with urologic trauma: a report of bladder extravasation into the hip joint.

A case of blunt trauma is presented with pelvic ring disruption and an extraperitoneal bladder rupture that communicated with the hip joint through an acetabular fracture. Extraperitoneal bladder rupture is usually associated with blunt polytrauma and pelvic ring injuries. Expedient diagnosis and multidisciplinary management are essential to minimize significant early and late complications.

Hip joint communication with pressure sore: the refractory wound and the role of Girdlestone arthroplasty.

Fifteen patients who underwent Girdlestone arthroplasty (proximal femoral head resection) were reviewed at The Johns Hopkins Hospital and Northwestern Memorial Hospital. Ages ranged from 24 to 57 years (mean 36.7 years). All patients were paraplegics or quadriplegics (C7-L3). All patients presented with signs of sepsis and had evidence of osteomyelitis. Soft-tissue reconstruction was most commonly performed with the vastus lateralis, and no femoral stabilization was used. There were no deaths. Recurrent ulcers at the site of the Girdlestone arthoplasty were found in 23 percent of patients in whom follow-up was possible. No recurrence was noted at the original site in 77 percent with a mean follow-up of 20 months. Additional pressure sores occurred at other nonsurgical sites in six patients at a mean of 23.3 months. Girdlestone arthroplasty with soft-tissue coverage is mandatory for successful treatment of pressure sores with hip joint involvement.

[Nuclear medical diagnosis of hip joint diseases in adults].

Skeletal scintigraphy has a high sensitivity but low specificity in early detection and follow up of hip diseases. Unexplained hip pain or indistinct X-rays may be the reason for scintigraphic examination. On the other hand, there is a wide range of clinical indications for nuclear medicine examination, such as metastatic and primary malignant disease, tumor-like lesions, inflammatory, infectious, degenerative and avascular diseases, and posttraumatic and postoperative changes. White blood cell scintigraphy is highly sensitive and highly specific in the detection of infectious disease of the hip. In the vast majority of cases, physiologic or postoperative granulocytic accumulation can be differentiated from infectious accumulation, which requires therapy.

[Early experiences with the total mini hip-joint endoprosthesis (St. George Mini model) in dysplasia coxarthrosis].

The results of 106 patients with osteoarthritis secondary to severe congenital hip dysplasia and dislocations of the hip operated at the Endo-Klinik were evaluated after an average follow up of 21 months. 142 "St. Georg-Mini" total hips were implanted employing Refobacin-Palacos R. The clinical results were graded as "combined performance" which considered hip pain, walking distance, hip mobility and walking aids. In 93% of the cases "combined performance" was improved at follow up and 91.7% of the patients were satisfied with the result. The early (during hospitalization) and late (after discharge from hospital) complication rate which had an influence on the result at follow up was 2.1% (n = 3) and 3.5% (n = 4) respectively. There were no deep infections. An extended indication for total hip arthroplasty also for younger patients with severe osteoarthritis secondary to hip dysplasia is discussed and can be advocated.

Raman spectroscopic analysis of phase-transformation and stress patterns in zirconia hip joints.

Confocal Raman piezo-spectroscopy has been used for the quantitative assessments of phase transformation and residual stresses in zirconia made artificial hip joints. This work can be considered to be a first step towards the development of a fully quantitative technique for the spectroscopic characterization of zirconia femoral heads and other zirconia parts for biomedical applications. After establishing reliable calibration procedures, Raman microprobe spectroscopy could be extended to provide quantitative assessments of zirconia metastability and microscopic stress fields along the z axis perpendicular to the joint surface. For the first time, we have directly visualized patterns of phase-transformation and related residual stresses on the very surface and along the subsurface of both in vitro tested and retrieved hip implants. These spectroscopic assessments may open a completely new perspective in understanding the micromechanical wear behavior of zirconia ceramics in biological environment and in developing new zirconia-based biomaterials with superior stability characteristics.

The total cost of hip-joint replacement; a model for purchasers.

A computer-based model is used to investigate the total cost of primary total hip-joint replacement. The model takes into account the probability of prosthesis failure, death and re-revision. The results emphasize the importance of age at insertion, demonstrating that the expected life-span of the patient has a major influence on the total cost for a given prosthesis. The discussion considers the idea of a 'lifetime care package' to encapsulate the concept of quality when considering the purchasing of total hip replacements. If it is assumed that a primary replacement episode costs 3500 pounds and revision surgery costs twice as much, then the additional premium on the best implant currently available would be 630 pounds. The premium payable on the same patient using the worst design would be 3080 pounds. This difference reflects the importance of quality in total hip replacement surgery.
