Abstract
OBJECTIVE: To determine the direct cost of complete cervical spinal cord injury.
MATERIAL AND METHODS: 34 patients over 16 years of age with a diagnosis of complete cervical spinal cord injury. The cost calculation was done considering nine groups: bed days, specialty consultation, laboratory, X-rays, computed axial tomography, magnetic resonance imaging, anterior surgery, posterior surgery, anterior and posterior surgery. The micro costing technique was used and the mean cost per patient was obtained.
RESULTS: 41% of patients had injury at C4-C5; mean age was 36 years; total cost was $8,622,793.00 mexican pesos, and the mean cost in patients who survived was $2,536,115.59 mexican pesos, which represented 29.4% of the total cost; the cost for the patients who died was $6,086,677.41 mexican pesos (70.6%). The percent distribution of the different components analyzed clearly shows that 51% of the total cost corresponded to hospitalization. The estimated annual cost of caring for these patients is $2,155,905.70 Mexican pesos, with an annual increase of $819,905.53 Mexican pesos.
CONCLUSIONS: The major cost was hospitalization, so specific clinical management guidelines should be used to optimize economic resources and prevent complications that may increase the costs.

Abstract
INTRODUCTION: Multiple strategies have been developed looking for upgrading the consolidation rate of spine arthrodesis with autolog bone graft, but no evidence exists that adhesion with Collagen type 1 and polyvinylpyrrolidone (FibroquelMR) have application on this field.
OBJECTIVE: Determine if collagen type 1 + Polyvinylpyrrolidone are effective as bone enhancer in posterolateral arthrodesis on rabbits.
METHOD: Posterolateral arthrodesis in 15 New Zealand rabbits on level L5-L6 using autolog bone graft in left side (control group) and autolog bone graft + 1 ml FibroquelMR (study group) in right side of arthrodesis. Euthanasia and block resection of lumbar segment eight weeks post surgery. Radiographic analysis, manual exploration and light microscopy of fussed segments.
RESULTS: Radiographic consolidation was observed in 80% in control group and 95% in study group, interleaved trabecular pattern with bone continuity and normal characteristics in 12 left sides and 14 right sides.
CONCLUSION: Collagen type 1 and polyvinylpyrrolidone use is likely to have positive effect in bone consolidation process, therefore it can be recommended to use it as a bone enhancer.

Abstract
BACKGROUND: Femoroacetabular impingement (FAI) is a suggested diagnosis for pain in the hip in the absence of other apparent causes. It is thought to be a cause of progressive arthrosis of the hip. Our objective was to determine the prevalence of radiographic data of FAI in the adult population without hip pathology over a period of six months.
MATERIAL AND METHODS: Analytical, observational, multicentric, ambispective and transverse study based on digital X-rays analysis. Measurements of the lateral center-edge angle of Wiberg, acetabular inclination, Tönnis angle and the neck shaft angle of the proximal femur were made; a pistol grip deformity of the femoral head, the triangular index and the shape of the coxofemoral joint were also evaluated.
RESULTS: From a total of 212 hips evaluated, 104 were in males and 108 in females, with an average age of 42.81 years; 21 had a pistol grip deformity and a positive triangular index for cam type. The pincer type was found in 12 hips.
DISCUSSION: In this multicentric study, the FAI cam type predominated in men on the right side; the pincer type predominated in women on the left side; this is similar to what has been reported in other populations. This study is limited by the wide variation in the femoral rotation; as an advantage, it was randomly carried out and provides some data on the prevalence of deformities of the hip, not previously registered.
