bookPart Osteonecrose da cabeça femoral em pessoas convivendo com HIV/Aids(2013) EJNISMAN, Leandro; GURGEL, Henrique Melo de Campos; MARIN, Júlio Cesar Martinez; CABRITA, Henrique A. Berwanger- Proposal for a new clinical test for diagnosing lateral hip snapping,(2014) CABRITAA AMORIM, Henrique Antonio Berwanger de; GURGELA, Henrique Melo de Campos; MARQUES, Ricardo; SANTOS, Leandro Emilio Nascimento; VICENTEA, José Ricardo Negreiros; LEONHARDTA, Marcos de Camargo; EJNISMANA, Leandro; CROCI, Alberto TesconiLateral hip snapping is a nosological entity that is often unknown to many orthopedists and even to some hip surgery specialists. It comprises palpable and/or audible snapping on the lateral face of the hip that is sometimes painful, caused by muscle-tendon friction on the greater trochanter during flexion and extension of the coxofemoral joint. In the following, we describe a new test for diagnosing lateral hip snapping, which is eminently clinical.
- A comparative radiographic investigation of femoroacetabular impingement in young patients with and without hip pain(2012) MIGUEL, Omar Ferreira; CABRITA, Henrique Berwanger de Amorim; RODRIGUES, Marcelo Bordalo; CROCI, Alberto TesconiOBJECTIVE: To compare the existence of radiographic abnormalities in two groups of patients, those with and without hip pain. METHODS: A total 222 patients were evaluated between March 2007 and April 2009; 122 complained of groin pain, and 100 had no symptoms. The individuals in both groups underwent radiographic examinations of the hip using the following views: anteroposterior, Lequesne false profile, Dunn, Dunn 45 degrees, and Ducroquet. RESULTS: A total of 1110 radiographs were evaluated. Female patients were prevalent in both groups (52% symptomatic, 58% asymptomatic). There were statistically significant differences between the groups in age (p < 0.0001), weight (p = 0.002) and BMI (p = 0.006). The positive findings in the group with groin pain consisted of the presence of a bump on the femoral head in the anteroposterior view (p < 0.0001) or in the Dunn 45 degrees view (p = 0.008). The difference in the alpha angle in the anteroposterior, Dunn, Dunn 45 degrees, and Ducroquet views for all of the cases studied was p, 0.0001. The joint space measurement differed significantly between groups in the Lequesne view (p = 0.007). The Lequesne anteversion angle (rho) and the femoral offset measurement also differed significantly (p = 0.005 and p = 0.0001, respectively). CONCLUSIONS: We conclude that the best views for diagnosing a femoroacetabular impingement are the anteroposterior pelvic orthostatic, the Dunn 45 degrees, and the Ducroquet views. The following findings correlated with hip pain: a decrease in the femoral offset, an increase in the a angle, an increase in the Lequesne r angle, a decrease in the CE angle of Wiberg, a thinner articular space and the presence of a bump on the femoral head-neck transition.
- Acetabular Component Positioning in Total Hip Arthroplasty With and Without a Computer-Assisted System: A Prospective, Randomized and Controlled Study(2014) GURGEL, Henrique M. C.; CROCI, Alberto T.; CABRITA, Henrique A. B. A.; VICENTE, Jose Ricardo N.; LEONHARDT, Marcos C.; RODRIGUES, Joao CarlosIn a study of the acetabular component in total hip arthroplasty, 20 hips were operated on using imageless navigation and 20 hips were operated on using the conventional method. The correct position of the acetabular component was evaluated with computed tomography, measuring the operative anteversion and the operative inclination and determining the cases inside Lewinnek's safe zone. The results were similar in all the analyses: a mean anteversion of 17.4 degrees in the navigated group and 14.5 degrees in the control group (P = .215); a mean inclination of 41.7 degrees and 42.2 degrees (P = .633); a mean deviation from the desired anteversion (15 degrees) of 5.5 degrees and 6.6 degrees (P = .429); a mean deviation from the desired inclination of 3 degrees and 3.2 degrees = .783); and location inside the safe zone of 90% and 80% (P = .661). The acetabular component position's tomography analyses were similar whether using the imageless navigation or performing it conventionally.
- Hip arthroscopy(2015) CABRITA, Henrique Antônio Berwanger de Amorim; TRINDADE, Christiano Augusto de Castro; GURGEL, Henrique Melo de Campos; LEAL, Rafael Demura; MARQUES, Ricardo da Fonseca de SouzaHip arthroscopy is a safe method for treating a variety of pathological conditions that were unknown until a decade ago. Femoroacetabular impingement is the commonest of these pathological conditions and the one with the best results when treated early on. The instruments and surgical technique for hip arthroscopy continue to evolve. New indications for hip arthroscopy has been studied as the ligamentum teres injuries, capsular repair in instabilities, dissection of the sciatic nerve and repair of gluteal muscles tears (injuries to the hip rotator cuff), although still with debatable reproducibility. The complication rate is low, and ever-better results with fewer complications should be expected with the progression of the learning curve.
- Necrose avascular da cabeça femoral em pacientes HIV positivos: resultados iniciais do tratamento cirúrgico por substituição articular cerâmica-cerâmica(2012) CABRITA, Henrique Amorim; SANTOS, Alexandre Leme de Godoy; GOBBI, Riccardo Gomes; LIMA, Ana Lúcia Munhoz; OLIVEIRA, Priscila Rosalba; EJNISMAN, Leandro; GURGEL, Henrique Melo Campos; UIP, David; CAMANHO, Gilberto LuisOBJECTIVES: To evaluate the initial functional results and early complication rate of ceramic-ceramic total hip replacements among patients living with HIV who presented osteonecrosis of the femoral head. METHOD: Twelve HIV-positive patients with a diagnosis of osteonecrosis of the incongruent femoral head were evaluated using clinical and laboratory criteria and the WOMAC functional scale before and after treatment with joint replacement. RESULTS: We observed that 83.3% of the subjects were taking protease inhibitors, 75% had dyslipidemia and 66.6% had lipodystrophy syndrome. The improvement over the evolution of the WOMAC score was statistically significant at six and twelve months after the operation, in comparison with the preoperative score. We did not observe complications secondary to this procedure. CONCLUSION: Total hip arthroplasty with a ceramic-ceramic implant for treating avascular necrosis of the hip is an appropriate surgical option for this portion of the population. It provides a significant initial functional improvement and a low early complication rate.
