- 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.
- Osteonecrosis of the Femoral Head: Update Article(2022) MIYAHARA, Helder de Souza; RANZONI, Lucas Verissimo; EJNISMAN, Leandro; VICENTE, José Ricardo Negreiros; CROCI, Alberto Tesconi; GURGEL, Henrique Melo de CamposAbstract Among the pathologies that affect the hip joint, osteonecrosis of the femoral head (ONFH) is probably the most intriguing and challenging. It consists of a multifactorial disease with a highly-variable spectrum in its clinical presentation. It has a devastating effect, due to disabling painful conditions, both for usual activities and sports. Given the huge range of risk factors, such as prolonged use of corticosteroids (especially in cases of rheumatologic diseases), trauma sequelae, sickle cell anemia, HIV, alcoholism, smoking, blood dyscrasias, and several other diseases that compromise the blood supply to the femoral head, ONFH has a varied clinical presentation and prognosis, which makes it difficult to determine a specific treatment, especially in cases in which chondral involvement has not yet occurred and the hip joint is still preserved. These are the main factors found in the literature that determine the classifications of this pathology. The range of treatments includes several options for cases in which an attempt is made to save the joint: conservative treatment, traditional decompression and/or combined with some type of adjuvant treatment (homologous grafting, synthetic grafting, vascularized grafts, tantalum screws, and bone marrow aspirate injection), and, for cases in which there is already a subchondral fracture and/or collapse of the femoral head and/or a reduction in the joint space, femoral osteotomies or total hip arthroplasty are commonly performed.
- ETHICAL AND LEGAL ASPECTS OF TELEMEDICINE APPLIED IN ORTHOPEDICS(2022) YAMAGUCHI, Fabio Seiji MAzz I.; MIYHARA, Helder De Souza; SILVA, Jorge dos santos; RUDELLI, Bruno alves; EJNISMAN, Leandro; GURGEL, Henrique melo de camposDue to the pandemic of COVID-19, many outpatient services were suspended, affecting hundreds of patients. As a result, several countries were forced to seek strategies to readapt their health systems, one of which was the expansion of telemedicine. Currently, telemedicine is used for several specialties, facilitating the treatment and follow-up of patients who have difficulty accessing it. Tele-orthopedics, telemedicine applied to the orthopedic specialty, allows orthopedic care to be offered to patients regardless of orthopedics presents high patient satisfaction, allowing greater rehabilitation effectiveness after surgery and treatment compliance. There is much information in the current literature about telemedicine's legal and ethical aspects, but it is fragmented. and ethical aspects, emphasizing tele-orthopedics. The ethical principles of autonomy, beneficence, non-maleficence and justice must be respected, as well the privacy and confidentiality during use. Level of Evidence V: Expert Opinion.
- Cementless Total Hip Arthroplasty in Patients with Osteoarthrosis Secondary to Legg-Calvé-Perthes Disease Compared with Primary Osteoarthrosis: A Case-control Study(2022) SANSANOVICZ, Dennis; CROCI, Alberto Tesconi; VICENTE, José Ricardo Negreiros; EJNISMAN, Leandro; MIYAHARA, Helder de Souza; GURGEL, Henrique de Melo CamposAbstract Objective To perform a comparative clinical, functional and radiographic evaluation of total hip arthroplasty (THA) performed with a cementless prosthesis in cases of osteoarthrosis secondary to Legg-Calvé-Perthes Disease (LCPD) and in cases of primary osteoarthrosis. Methods In the present case-control study, we reviewed medical records of patients admitted to a university hospital between 2008 and 2015 to undergo THA due to LCPD sequelae and compared them with a control group of patients who underwent the same surgery due to primary hip osteoarthrosis. We recruited patients for clinical, functional, and radiographic analysis and we compared the evaluations in the immediate postoperative period and at the last follow-up visit, considering surgical time, size of prosthetic components, and complications. Results We compared 22 patients in the study group (25 hips) with 22 patients (25 hips) in the control group, all of whom had undergone THA with the same cementless prosthesis. There was greater functional impairment in the group of patients with LCPD sequelae (p= 0.002). There were 4 intraoperative femoral periprosthetic fractures in the LCPD group and none in the primary osteoarthrosis group (p= 0.050). Conclusions There is an increased risk of intraoperative periprosthetic femoral fracture and worse clinical-functional results in patients undergoing cementless THA due to osteoarthrosis secondary to LCPD sequelae than in those who have undergone the same surgery due to primary hip osteoarthrosis.
- 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.
