Fifteen-year results of the Müller CoCrNiMo straight stem.

Between September 1980 and May 1982, 112 primary unilateral total hip arthroplasties with the original cemented M. E. Müller Straight stem (manufactured from Protasul-10, a CoCrNiMo alloy) were inserted in 109 consecutive patients, all combined with non-cemented, non-coated polyethylene RM cups. Forty-three patients (40%) died during the follow-up period, all with the implant in place. Of the 66 surviving patients, 2 (1.8%) were lost to follow-up, and 7 (6.3%) were unable to attend the 15-year clinical and radiological follow-up. Eight stems (7.3%) had to be revised for aseptic loosening and 3 stems (2.7%), for septic loosening. The 15-year survivorship of the Müller Straight stem regarding aseptic loosening is, therefore, 92.7%. Forty-six patients with 49 total hip replacements could be evaluated clinically and radiologically after 15 years. The mean duration of clinical follow-up for these 46 patients (42.2%) was 14.8 years (range 12.8-16.5 years). There were 22 women (48%) and 24 men (52%). The mean age at the time of the operation was 62 years (range 38-80 years), and 78 years (range 59-93 years) at the time of the latest follow-up. The mean Harris Hip Score at the latest follow-up evaluation of the 49 hip joints was 85 points (range 34-100 points). Of the 46 patients, 39 (85%) had a good or excellent clinical result. Radiographic follow-up was performed for 49 hips: 35 (70%) had linear or focal osteolysis in one or more zones of the stem, but only 4 (8%) had evidence of definitive loosening (linear radiolucency of over 2 mm all around the stem). Subsidence of over 2 mm was found in 20 hips (41%), 6 of them within the cement mantle. There was no correlation between subsidence and pain. The cause for the poor results is primarily the high rate of aseptic loosening of the non-coated, non-cemented all-polyethylene RM cups, with a loosening rate of 63% and a revision rate of 25% after 15 years.

Judging outcomes in psychosocial interventions for dementia caregivers: the problem of treatment implementation.

PURPOSE: In published dementia caregiver intervention research, there is widespread failure to measure the level at which treatment was implemented as intended, thereby introducing threats to internal and external validity. The purpose of this article is to discuss the importance of inducing and assessing treatment implementation (TI) strategies in caregiving trials and to propose Lichstein's TI model as a potential guide. DESIGN AND METHODS: The efforts of a large cooperative research study of caregiving interventions, Resources for Enhancing Alzheimer's Caregiver Health (REACH), illustrates induction and assessment of the three components of TI: delivery, receipt, and enactment. RESULTS: The approaches taken in REACH vary with the intervention protocols and include using treatment manuals, training and certification of interventionists, and continuous monitoring of actual implementation. IMPLICATIONS: Investigation and description of treatment process variables allows researchers to understand which aspects of the intervention are responsible for therapeutic change, potentially resulting in development of more efficacious and efficient interventions.

[Comparative results after endoscopic synovectomy and open bursectomy in chronic bursitis olecrani].

UNLABELLED: The surgical treatment of choice in cases with chronic bursitis of the elbow usually consists of an open radical bursectomy. PURPOSE OF THIS STUDY: Comparison of the outcome after the endoscopic synovectomy and internal drainage with the conventional operative procedures (control). METHODS: Clinical follow-up in nine endoscopically treated patients and conventionally operated controls in the similar year that were comparable in age and number of prior surgical procedures in that region. Comparison by means of the score of Morrey et al. using Mann-Whitney-U-test and chi 2-test. DISCUSSION: All patients in both groups were highly satisfied with the results of their treatment. The analysis revealed no differences in score Morrey et al. (endoscopy: 97.11 points vs. control: 95.33 points; p = 0.564). However, the endoscopically treated patients returned significantly earlier to work (10 d vs. 18 d, p = 0.041). CONCLUSION: The endoscopical synovectomy in cases with chronic bursitis olecrani is an easy and safe method to obtain excellent results.

Recurrent acute hemarthrosis after anterior cruciate ligament reconstruction. Report of an unusual complication and a review of the literature.

Arthroscopic-assisted and endoscopic operative techniques have allowed for less and less restrictive postoperative rehabilitation programs after cruciate ligament reconstruction. Accelerated rehabilitation programs may, however, also provoke mechanical problems at the transplant-bone interface, as reports in the literature of loosened fixation devices and loosened or even fractured bone pegs with subsequent hemarthrosis and recurrent instability have shown. We describe the case of a patient who presented with recurrent acute hemarthrosis after anterior cruciate ligament reconstruction without additional trauma and without instability. However, the symptoms and signs were clearly related to the fixation method employed.
