- 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.
- Bacteria drug resistance profile affects knee and hip periprosthetic joint infection outcome with debridement, antibiotics and implant retention(2020) RUDELLI, Bruno Alves; GIGLIO, Pedro Nogueira; CARVALHO, Vladimir Cordeiro de; PECORA, Jose Ricardo; GURGEL, Henrique Melo Campos; GOBBI, Ricardo Gomes; VICENTE, Jose Riccardo Negreiros; LIMA, Ana Lucia Lei Munhoz; HELITO, Camilo PartezaniBackground Evaluate the effect of bacteria drug resistance profile on the success rates of debridement, antibiotics and implant retention. Methods All early acute periprosthetic infections in hip and knee arthroplasties treated with DAIR at our institution over the period from 2011 to 2015 were retrospectively analyzed. The success rate was evaluated according to the type of organism identified in culture: multidrug-sensitive (MSB), methicillin-resistantStaphylococcus aureus(MRSA), multidrug-resistant Gram-negative bacteria (MRB) and according to other risk factors for treatment failure. The data were analyzed using univariate and multivariate statistics. Results Fifty-seven patients were analyzed; there were 37 in the multidrug-sensitive bacteria (MSB) group, 11 in the methicillin-resistantStaphylococcus aureus(MRSA) group and 9 in the other multidrug-resistant Gram-negative bacteria (MRB) group. There was a statistically significant difference (p < 0.05) in the treatment failure rate among the three groups: 8.3% for the MSB group, 18.2% for the MRSA group and 55.6% for the MRB group (p = 0.005). Among the other risk factors for treatment failure, the presence of inflammatory arthritis presented a failure rate of 45.1 (p < 0.05). Conclusion DAIR showed a good success rate in cases of early acute infection by multidrug-sensitive bacteria. In the presence of infection by multidrug-resistant bacteria or association with rheumatic diseases the treatment failure rate was higher and other surgical options should be considered in this specific population. The MRSA group showed intermediate results between MSB and MRB and should be carefully evaluated.
- FEMORAL HEAD DECOMPRESSION AND GRAFT: TECHNIQUE WITH NEW INSTRUMENTS(2022) MIYAHARA, Helder De Souza; RUDELLI, Bruno Alves; RANZONI, Lucas Verissimo; EJNISMAN, Leandro; VICENTE, Jose Ricardo Negreiros; GURGEL, Henrique Melo De CamposIntroduction: Osteonecrosis of the femoral head (ONFH) is a pathol-ogy that can be treated with many approaches by the hip surgeon. Advanced decompression is a technique that aims to prevent the collapse of the femoral head and the arthrosis process of the joint, a technique already widespread and used by hip surgeons. In this study, we performed the technique with a new retractable blade and a new bone substitute as graft for the femoral head. Objective: To evaluate the technique with new instruments (EasyCore Hip (R)) and a calcium phosphate bone substitute (Graftys (R) HBS). Methods: Patients with osteonecrosis of the femoral head without major degenerative changes, such as femoral head collapse, were selected. Femoral head decompression was performed using the EasyCore Hip (R) retractable blade along with the calcium phosphate bone substitute as graft (Graftys (R) HBS). Results: The instruments proved to be reliable and reproducible, and the bone substitute presented good mechanical resistance, maintaining its temperature during the surgery. The dis-posable retractable blade presents variation in size and angle, which is an advantage in the removal of necrotic bone. However, we must take some precautions in order to achieve a better result. Conclusion: using EasyCore Hip (R) instruments and a calcium phosphate bone substitute (Graftys (R) HBS) is safe; however, some precautions must be taken during the use of the technique.
