A common common illness, incurable, osteodistrofia (OA) are the root cause of the inability in aged peoples. When almost all the junction could be affected, the OA hits knee the more frequent, particularly the internal aspect of the tibiofemoral junction. A source of stress in this vulnerable common compartment is the moment of adduction of […]

Together with the age and the wounds, obesity is a factor of main risk for the osteodistrofia (OA), a painful common illness and incapacitating. When the extreme weight will be able aggravate the toll in almost all the junction, obesity estve associated with one prevalence more raised of hip OA and an increase in hip total arthroplasty (THA). If the patients obese of the OA of hip are more prone to the complications postsurgical, however, to remains opened to the debate and the inquiry, since that the results of existing studies oppose. What it is more, only some studies short-term had focused in as obesity affects the results of revision THA. A longer procedure is compared with the preliminary surgery of the THA revision and more complicated than it implies the damages most extensive of the fabric and a greater risk of prosthetic common infections and dislocations, as.well.as other complications in the long run.

The investigators in hospitals of the university of Geneva had been adjusted for are to after evaluate the impact of obesity in the incidence of serious complications revision THA, on a period of up to 5 years. The team also pointed to determine if the improvement, pain, and the satisfaction functional 5 years the second replacement of hip had after differed between patients obese and patients from the healthful weight. Its results, presented in the introduction of May 2008 of the care & the research of the arthritis, disclose to a strong correlation between obesity and high taxes of adverse events, as.well.as lower functional profits and a more persistent pain, after revision THA.

This study in the long run it focused in all the patients whom if they had submitted to a revision THA, excluding re-revisions, in the hospital of the university - the only public hospital that serves to the urban and suburban populations of Geneva, Switzerland - between 1966 and 2006. Of the 204 subjects, 114 were women and 90 were men, with an average age of 71.6 years. Based in the data of the height and the weight gotten immediately before the surgery, 52 patients, 25 percent of the sample, had been defined as obese, with an index of the mass of the body (BMI) of 30 or more. The scale standard for a normal BMI, the ideal weight to the relation of the height, is between 18 and 25. To more more evaluate the association between BMI and results postoperative, the patients had also been examined in 4 categories of BMI: less than 25; 25 the 29,9, defined as overweight; 30 the 34.9; e 35 or more.

Based in registers and patient examinations of the continuation, the investigators had first registered the occurrence of one or more adverse event inside of 5 years after first revision THA: surgical infection of the place, dislocation of hip prosthetic, or surgery of the re-revision for some cause. They had trusted then trusted, hip-specific clinical evaluations, including the counting of hip of Harris (HHS), together with interviews of the in-person and the telephone with patients, to measure the functional status of each subject, the level of pain, and the general satisfaction with the procedure 5 years later. Finally, the investigators had used statistical analyses, including taxes of the incidence and relations of the danger, to compare the results between patients after obese and non-non-obese revision THA.

Totals, 20 complications had occurred in 17 (33 percent) of the 52 patients obese, compared with the 18 events in 13 (9 percent) of the 152 patients non-non-obese. In the terms of specific complications, the tax of incident was 4 times more highly for the surgical infection of the place and 3,5 times more highly for dislocation. Exactly more to hit, the tax of the incidence for an occurrence of one or more adverse event had been arisen with BMI arising itself. This increase was small between normal patients and overweight - 1,5 time more highly. Still, one became more highly significantly greater in the group with a BMI between 30 and 34.9 - 4,5 patients of the one than the normal ones of the weight of the times. E more scaled alarmingly to an increase in the group with a BMI of the 35 or - 10,9 times more highly. In these calculations, the adjustments had been executed for the age, the sex, and the status of health preoperative.

For those patients programmed for one it visits of a continuation of 5 years, 83 percent of the 85 patients obese and percent of the patients non-non-obese were available for the evaluation. In the general, the patients obese had had lower functional improvements moderate and raised levels more of hip routine cause pain. However, the patient satisfaction with the result of its revision THA was calibrated to be more or less identical in both the groups.

While its author of the linking, Dr. Anne Lbbeke, recognizes, this study he is limited by the relatively small number of adverse events having for result great intervals and restriction of the confidence of the adjustment for differences of the line of base between patients obese and non-non-obese to the most important factors of the confusion. Although such weaknesses, findings strengthen revision THA as an intervention technician-technically-challenging, particularly when executed in patients obese.

the “surgeons, the patients, and to consult doctors must be cliente of a risk increased in this patient group,” stresses of the Dr. Lbbeke. “more more the studies are necessary to evaluate if the changes in the medical preparation, the surgical technique, and the choice of implant can help to reduce the adverse tax of the event in the patients obese that they are submitted to revision THA.”
