OBJECTIVE To evaluate the safety of arthroscopic Latarjet procedure in cadavers. METHODS : Twelve cadaveric shoulders underwent arthroscopic Latarjet procedure in our laboratory for arthroscopy, by four different surgeons. Following surgery, the specimens were subjected to radiographic examination and evaluated by an independent examiner. Nineteen(More)
We studied the incidence and prognosis of acute neurologic complications in 281 children under 13 years of age with a diagnosis of acute bacterial meningitis. All the patients were examined daily by the same group of neurologists, using a standardized neurological examination. Patients with signs of encephalic lesions, unsatisfactory response to antibiotics(More)
We report two cases of craniocervical junction schwannomas with a special focus on the surgical approach. The patients underwent a far-lateral approach in the sitting position that facilitated the lesion removal. This report is meant to improve the understanding of this surgical technique as well as improve awareness of its usefulness for similar cases.
OBJECTIVE To identify prognostic factors of postoperative functional outcomes. METHODS Retrospective case series evaluating patients undergoing rotator cuff repair, analyzed by the UCLA score (pre and 12-month postoperative) and Magnetic Resonance Imaging (preoperative). Patients' intrinsic variables related to the injury and intervention were evaluated.(More)
OBJECTIVE To compare the viability of transferring the lower and transverse trapezius to the greater tuberosity using three different techniques. METHODS Twelve shoulders from six cadavers were used. The primary outcome was to assess the suture viability of the trapezius muscle transfer to the greater tuberosity in the insertion topography of the(More)
OBJECTIVES To evaluate the correlation between radiographic parameters and functional assessments of patients with osteoarthritis of the shoulder who underwent shoulder arthroplasty and to describe the functional outcomes of this procedure in our institution. METHODS We evaluated 21 patients (22 shoulders) who underwent shoulder arthroplasty between 1998(More)
Joint contractures are a common complication of hand trauma. The conventional treatment consists of arthrolysis, tenolysis and occasionally arthrodesis. Frequently, this does not achieve a good result, particularly when there has been a long delay in presentation. Progressive lengthening of a joint by distraction (joint distraction) allows the release of(More)
Data from the records of 528 children under 15 years old with diagnosis of acute bacterial meningitis, admitted at the Hospital Couto Maia between 1990 and 1992 were analyzed. Bacterial meningitis was more frequent in children under the age of 1 year (37.8%). The most common etiologic agent was H. influenzae (42.2%). The global lethality was 20.9%.(More)
Two cases of sickle cell disease with neurological complications are described. Cerebral angiograms were performed and a characteristic moyamoya-like angiographic pattern was demonstrated. This pattern results from a compensatory vascularization which may follow occlusion of the arteries at the base of the brain in several diseases. The risks of angiography(More)
A case of a 23 year-old-man with a history of polyarthritis and chronic tophaceous gout is reported. He developed a crural paraparesis caused by sodium urate deposits in the spinal canal. Decompressive laminectomy and removal of urate-laden ligamentum flavum was performed without improvement. According to the literature there are nine cases previously(More)
