ObjectiveTo scientifically prove the high number of patients with fractures coming from the small towns of the State of Ceará treated with surgery by the SUS (the Brazilian State healthcare system) in Fortaleza.MethodsA transversal, prospective, descriptive study was carried out involving 1694 patients treated by the SUS in Fortaleza, from August 2006 to March 2007, in four public hospitals and three private hospitals.Results38.78% of the patients came from small towns, and their ages ranged from 1 to 97 years old. The majority were single, male adults. The most common mechanism of injury was traffic accidents, accounting for 30.4% of all the cases. The forearm was the body segment most operated on, corresponding to 19%.ConclusionsThese results suggest there is a need for preventive measures, such as public traffic safety awareness campaigns, in order to reduce accidents. We have also verified the importance of investments aimed at developing the Traumatology Emergency services in the small towns of Ceará.

ObjectiveTo make a comparative analysis on three femoropatellar radiographic parameters, between knees with chronic failure of the anterior cruciate ligament (ACL) and normal knees.MethodsThirty volunteer patients with a diagnosis of unilateral isolated chronic ACL injury for more than one year and a normal contralateral knee were selected. Digital radiographs were produced for all the patients, on both knees in absolute lateral view at 30° of flexion, with and without load-bearing on one leg, and in axial view of the patella at 30°. The Caton–Deschamps patellar height index, Merchant patellar congruence angle and Laurin lateral patellar tilt angle were measured on the radiographs obtained from the normal knees and knees with ACL injuries, and comparative analysis was performed between these two groups.ResultsThe patellar height was statistically significantly lower (p < 0.001) in the knees with ACL failure than in the normal knees, both on radiographs without loading and on those with single-foot loading. The Merchant patellar congruence angle was significantly smaller (p < 0.001) in the normal knees and the lateral patellar tilt angle was smaller (p < 0.001) in the knees with ACL failure.ConclusionChronic ACL failure gave rise to a statistically significant change in the femoropatellar radiographic values studied (p < 0.001). Knees with injuries to this ligament presented lower patellar height values, greater tilt and lateral displacement of the patella, in relation to the femoral trochlea, in comparison with the normal contralateral knees.

The occurrence of permanent patellar dislocation associated with severe osteoarthritis is considered rare and difficult to treat. Literature: The literature is quite controversial on the subject. The objective of the study is to report two rare cases of severe osteoarthritis with permanent dislocation of the patella that underwent total knee arthroplasty, in addition to a review of the literature on the subject and related surgical technique. Total knee arthroplasty with using the medial parapatellar approach associated with lateral release was a good surgical option in patients with permanent patellar dislocation associated with advanced osteoarthritis.

Objectivethis study aimed to evaluate the fixation of the trabecular metal wedge in patients undergoing revision of total hip arthroplasty.Methodstwenty-three cases with minimum grading of Paprosky II-B that were operated between July 2008 and February 2013 were evaluated. These cases were evaluated based on radiographs before the operation, immediately after the operation and later on after the operation. Loss of fixation was defined as a change in the abduction angle of the component greater than 10° or any mobilization greater than 6 mm.Resultsit was found that there was 100% fixation of the acetabula after a mean of 29.5 months. One case underwent removal of the implanted components due to infection.Conclusionsthere is still no consensus regarding the best option for reconstructing hips with bone loss. However, revision using a trabecular metal wedge has presented excellent short- and medium-term results. This qualifies it as an important tool for achieving a fixed and stable acetabular component.
