- HISTOMORPHOMETRIC ANALYSIS OF THE FEMORAL NECK IN PATIENTS WITH AND WITHOUT FEMORAL NECK FRACTURE(2015) SOUZA, Caio Goncalves De; JORGETTI, Vanda; REIS, Luciene Machado Dos; CROCI, Alberto TesconiObjective: To determine, through bone histomorphometry in femoral neck, whether there are differences in the cancellous bone of the proximal femur from female patients over 60 years old who had femoral neck fracture and similar patients who did not have such fracture. Methods: We analyzed the trabecular part of the femur of 13 female patients, aged over 60 years old, by the bone histomorphometry method. Seven of these patients had femoral neck fracture. All of them were subjected to hip arthroplasty. Results: Bone densitometry showed no significant difference. There was no significant difference on the average thickness of the trabecular bone (124.38 mu m versus 147.09 mu m). The number of bone trabeculae was lower (1.52, versus 1.88) and the separation between them was larger (541,19 mu m versus 391,14 mu m) in the fracture group. Conclusion: A difference in histomorphometric parameters of cancellous bone of the femur neck was observed among patients who had fractures as compared to patients who had not.
- RADIOGRAPHIC EVALUATION OF OSSEOINTEGRATION OF UNCEMENTED TARGOS (R) STEMS. A 5-YEAR FOLLOW-UP(2022) MIYAHARA, Helder de Souza; NARCISO, Jorge Henrique; CORREA, Jose Guilherme Lollo; VICENTE, Jose Ricardo Negreiros; EJNISMAN, Leandro; RUDELLI, Bruno Alves; GURGEL, Henrique de Melo Campos; CROCI, Alberto TesconiIntroduction: Total hip arthroplasty is a widespread treatment and is considered the gold standard in cases of hip osteoarthritis, with high rates of success in improving pain and function when well performed. After five years of follow-up, this study evaluates the osseointegration of uncemented Targos (R) collared stems in arthroplasties. Methods: Observational study of 182 total hip arthroplasties performed in 2014 with Targos (R) cementless collared femoral stems (Lepine). Bone quality was assessed according to the Dorr scale and osseointegration according to the Engh score. Results: The overall mean age was 56.5 years, consisting of 104 men (57.1%) and 103 women (56.6%). The os-seointegration rate of the stems (total Engh>0) was 100%. There was no statistical difference between groups concerning age (p=0.262), gender (p=0.463), primary diagnosis (p=0.585), af-fected side (p=0.459), and degree of Dorr (p=0.857). Conclusion: Targos (R) cementless collared femoral stems showed excellent osseointegration in all patients evaluated, regardless of age, gender, and preoperative bone quality. Moreover, spot welds observed on preoperative radiographs have the best association with implant osseointegration. Level of evidence IV, case series.
- TWO CLASSIFICATIONS FOR SURGICAL WOUND HEMATOMA AFTER TOTAL HIP REPLACEMENT(2018) FAGOTTI, Lorenzo; EJNISMAN, Leandro; GURGEL, Henrique de Melo Campos; MIYAHARA, Helder de Souza; CROCI, Alberto Tesconi; VICENTE, Jose Ricardo NegreirosObjective: To determine the reliability of two classification methods for wound hematoma after total hip replacement. Methods: This prospective cohort study was conducted on patients who underwent total hip replacement for hip osteoarthritis between May 2014 and April 2015. Epidemiological, surgical, and functional data were assessed. Two experienced hip surgeons evaluated 75 pictures of wounds taken 24 hours after surgery. Both evaluators performed the analysis twice, with a 6-week interval between the two analyses. The subjective classification was divided into four different categories describing the hematoma: absent, mild, moderate, and severe. The objective classification was derived from mathematical calculation of the area of the hematoma using a grid superimposed on a picture of the wound. Results: The subjective classification demonstrated an intra-rater agreement of more than 70%, while kappa values showed poor to moderate inter-rater reliability. The objective classification based on mathematical measurements of the hematoma area was more reliable, with good to excellent intra-and inter-rater reliability. Conclusion: The objective classification demonstrated higher intra-and inter-rater reliability. The classification methods used in this study could serve as a useful instrument for orthopedic surgeons, researchers, and health care providers when assessing wound hematomas after total hip replacement.
- Translation and Validation of the Knee Society Score : KSS for Brazilian Portuguese(2012) SILVA, Adriana Lucia Pastore e; DEMANGE, Marco Kawamura; GOBBI, Riccardo Gomes; SILVA, Tania Fernanda Cardoso da; PECORA, Jose Ricardo; CROCI, Alberto TesconiObjective: To translate, culturally adapt and validate the ""Knee Society Score""(KSS) for the Portuguese language and determine its measurement properties, reproducibility and validity. Method: We analyzed 70 patients of both sexes, aged between 55 and 85 years, in a cross-sectional clinical trial, with diagnosis of primary osteoarthritis,undergoing total knee arthroplasty surgery. We assessed the patients with the English version of the KSS questionnaire and after 30 minutes with the Portuguese version of the KSS questionnaire, done by a different evaluator. All the patients were assessed preoperatively, and again at three, and six months postoperatively. Results: There was no statistical difference, using Cronbach's alpha index and the Bland-Altman graphical analysis, for the knees core during the preoperative period (p=1), and at three months (p=0.991) and six months postoperatively (p=0.985). There was no statistical difference for knee function score for all three periods (p=1.0). Conclusion: The Brazilian version of the Knee Society Score is easy to apply, as well providing as a valid and reliable instrument for measuring the knee score and function of Brazilian patients undergoing TKA. Level of Evidence: Level I - Diagnostic Studies Investigating a Diagnostic Test- Testing of previously developed diagnostic criteria on consecutive patients (with universally applied 'gold' reference standard).
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.
