- 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.
- Assessment of the function and resistance of sternoclavicular ligaments: A biomechanical study in cadavers(2014) NEGRI, J. H.; MALAVOLTA, E. A.; ASSUNCAO, J. H.; GRACITELLI, M. E. C.; PEREIRA, C. A. M.; BOLLIGER NETO, R.; CROCI, A. T.; FERREIRA NETO, A. A.Background: Few biomechanical studies have assessed the resistance of the ligamentous structures of the sternoclavicular joint, and none have reproduced the physiological movements of the joint. Determiningthe structures that are injured in sternoclavicular dislocations is important for the surgical planning of acute or chronic ligament reconstruction. Methods: Forty-eight joints from 24 human cadavers were studied, and they were divided into 4 groups of 12 joints each (retraction, protraction, depression and elevation). Biomechanical testing assessed primary and secondary failures. The mechanical resistance parameters between movements that occurred on the same plane (depression versus elevation, protraction versus retraction) were compared. Results: The posterior sternoclavicular ligament was the most injured structure during the protraction test, but it was not injured during retraction. The anterior sternoclavicular ligament was the most affected structure during retraction and depression. The costoclavicular ligament was the most affected structure during elevation. Joint resistance was significantly greater during protraction movements when compared to retraction (P < 0.05). Conclusion: The anterior sternoclavicular ligament was the most affected structure during retraction and depression movements. During protraction, lesions of the posterior sternoclavicular ligament were most frequent during elevation, and the costoclavicular ligament was the most frequently injured ligament. The resistance of the sternoclavicular joint was significantly greater during protraction movement when compared to retraction.
- 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.
- Clinical and epidemiological characteristics of septic arthritis of the hip, 2006 to 2012, a seven-year review(2014) MIYAHARA, Helder de Souza; HELITO, Camilo Partezani; OLIVA, Guilherme Batista; AITA, Paulo Cesar; CROCI, Alberto Tesconi; VICENTE, Jose Ricardo NegreirosOBJECTIVE: To epidemiologically characterize the population treated at our orthopedic clinic with a diagnosis of septic arthritic of the hip between 2006 and 2012. METHODS: Fifteen patients diagnosed with septic arthritis of the hip between 2006 and 2012 were retrospectively evaluated. The patients' clinical and epidemiological characteristics were surveyed; a sensitivity profile relating to the microorganisms that caused the infections and the complications relating to the patients' treatment and evolution were identified. RESULTS: Septic arthritis was more common among males. Most diagnoses were made through positive synovial fluid cultures, after joint drainage was performed using the Smith-Petersen route. Among the comorbidities found, the most prevalent were systemic arterial hypertension, diabetes mellitus, and human immunodeficiency virus. The pathological joint conditions diagnosed prior to joint infection were osteoarthrosis and developmental dysplasia of the hip. The infectious agent most frequently isolated was Staphylococcus aureus. From the clinical and laboratory data investigated, 53.33% of the cases presented with fever, and all except one patient presented with increased measures in inflammation tests. Gram staining was positive in only 26.66% of the synovial fluid samples analyzed. Six patients presented with joint complications after treatment was administered. CONCLUSION: S. aureus is the most common pathogen in acute infections of the hip in our setting. Factors such as clinical comorbidities are associated with septic arthritis of the hip. Because of the relatively small number of patients, given that this is a condition of low prevalence, there was no statistically significant correlation in relation to worse prognosis for the disease.
