- 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.
- 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.
- Comparison of total hip arthroplasty in osteoarthritis of mechanical and rheumatologic causes(2014) EJNISMAN, Leandro; LEONHARDT, Nathalia Zalc; FERNANDES, Laura Fillipini Lorimier; LEONHARDT, Marcos de Camargo; VICENTE, Jose Ricardo Negreiros; CROCI, Alberto TesconiObjective: To compare the use of uncemented implants in total hip arthroplasty in patients with rheumathologic diseases and mechanical osteoarthrosis. Methods: We retrospectively evaluated 196 patients who were operated by the Hip and Arthroplasty Surgery Group of the IOT-HCFMUSP between 2005 and 2009. Patients were divided into two groups: mechanical causes (165 patients) and rheumathologic causes (31 patients). Groups were compared between each other in age, gender and follow-up time. Osseointegration rate and percentage of failure in arthroplasty were evaluated. Results: No statistically significant difference was found in osseointegration rates (in both femoral and acetabular components) in both groups. The rates of revision surgery and implant survival also did not show statistically significant differences. Conclusion: The use of uncemented total hip arthroplasty did not show worse results in rheumathologic patients. Level of Evidence III, Retrospective Case Control Study.
article 1 Citação(ões) na Scopus HIP ARTHRODESIS: A MINIMUM 20 YEAR FOLLOW-UP RETROSPECTIVE STUDY(2011) VICENTE, Jose Ricardo Negreiross; ULHOA, Carlos Antonio Soares; LEONHARDT, Marcos Camargo; FERNANDESPIRES, Andre; EJNISMAN, Leandro; TESCONICROCI, AlbertoObjective: To evaluate the long-term results of seventy patients who underwent hip arthrodesis using the original technique described by Davis. Methods: We carried out a retrospective study involving seventy patients submitted to hip arthrodesis between 1982 and 1995. The presence of symptoms involving the lumbar spine, ipsilateral knee, and contralateral hip was noted, as well as the success of the arthrodesis fusion, its positioning, and the need for conversion surgery to total hip replacement. Results: The mean follow-up time was 21.6 years. A satisfactory hip fusion was found in 48 patients (85.7%). Lumbar spine pain was reported by 11 patients (19.6%) and ipsilateral knee osteoarthritis was found in four patients (7.1%). Discussion: Two works, with a longer follow-up time (35 and 38 years) present more prevalent symptoms involving the lumbar spine (57% and 62%) and ipsilateral knee joint (45% and 57%), and higher conversion surgery rates (17% e 28%). Conclusion: Hip arthrodesis by the Davis technique presents satisfactory results until the 20(th)year after surgery, however lumbar spine disease seems to become more prevalent over the years, and the pain in the homolateral knee suggests an association with the initial position in abduction of the hip submitted to arthrodesis. Level of Evidence: Level Ill clinical study.
