ABSTRACT

Background: The objective of this study is the description of the secondary complications of obesity that may occur in patients undergoing transpedicular instrumentation who have spondylolisthesis. Obesity is a public health problem in our country, and is known to be associated with multiple diseases widely known, including the present problems related to the spine. Spondylolisthesis sometimes requires surgical management. Any surgery can have complications, but the risk is greater when they are associated factors as obesity and overweight.
Methods: Case-Control Study type (level III evidence). We studied 29 patients diagnosed with spondylolisthesis who underwent instrumentation transpedicuar in the period January 2005 to 2009 that met the inclusion criteria, and performed the filling of a sheet of capture, which contained data such as clinical records, clinical parameters, degree of spondylolisthesis according to the Meyerding classification, surgery factors and finally classified the degree of fusion.
Results: Were 19 (65.5%) located as obese and 10 (34.5%) and non-obese. Mean age was 51 years of which 18 (62.1%) patients were female and 11 (37.9%) were male, with an average weight of 79 kg +/- 14, average height of 1.64 meters +/- 0.08 and an average BMI of 29.4 +/- 4.4. Spondylolisthesis Grade II was the most common. As for the factors of surgery, 28 (96.6%) patients were placed graft. According to the radiological classification (Table 1) fusion patients had a mean body mass index of 25; non-fusion patients had a mean body mass index of 30.9. Of the 19 obese, 1 had complete and 18 non-merger merger. Of the 10 non-obese, 7 and 3 had fusion fusion.
Conclusions: In surgery for spondylolisthesis there are a number of risk factors that can affect the success of the surgery, including obesity can lead to a disastrous result because from the statistical point of view there is a probability of 42 times higher for non-fusion or nonunion.
It is important to emphasize that obesity does affect the success of postoperative patients undergoing surgery for spondylolisthesis, even there was an increase three times greater risk of nonunion in overweight patients (BMI› 25).
