RESUMO
OBJECTIVE: Conical orthopedic drill bits may have the potential to improve the stabilization of orthopedic screws. During perforations, heat energy is released, and elevated temperatures could be related to thermal osteonecrosis. This study was designed to evaluate the thermal behavior of an experimental conical drill bit, when compared to the conventional cylindrical drill, using polyurethane blocks perforations. RESULTS: The sample was divided into two groups, according to the method of drilling, including 25 polyurethane blocks in each: In Group 1, perforations were performed with a conventional orthopedic cylindrical drill; while in Group 2, an experimental conical drill was used. No statistically significant difference was observed in relation to the maximum temperature (MT) during the entire drilling in the groups, however the perforation time (PT) was slightly longer in Group 2. Each drill bit perforated five times and number of perforations was not correlated with a temperature increase, when evaluated universally or isolated by groups. The PT had no correlation with an increase in temperature when evaluating the perforations universally (n = 50) and in Group 1 alone; however, Group 2 showed an inversely proportional correlation for these variables, indicating that, for the conical drill bit, drillings with longer PT had lower MT.

Surgical site infections (SSI) constitute 31% of all hospital-acquired conditions, with ankle and foot surgical procedures showing an incidence of SSI ranging from 0.5% to 6.5%. This study aimed to assess the incidence of both superficial and deep surgical site infections in foot and ankle surgery, along with associated factors. Conducted as a retrospective cohort study, it included 2180 patients undergoing foot and ankle surgery in a private hospital between 2014 and 2020, encompassing elective and trauma cases. Outcome variables comprised SSI, while predictor variables encompassed sex, age, diabetes mellitus, systemic arterial hypertension, smoking, American Society of Anesthesiologists (ASA) score, and body mass index. Logistic regression models were employed to identify associations between study variables. The incidence of surgical site infections stood at 4% (83/2180), comprising a rate of 2.8% (57/2180) for superficial infections and 1.2% (26/2180) for deep infections. Smoking (OR 2.9, 95%CI 1.4-5.3) and ASA score >2 (OR 3.4, 95%CI 1.2-8.4) emerged as independent factors associated with surgical site infections. The group with deep infections exhibited higher proportions of smokers (p = 0.002), systemic arterial hypertension (p = 0.018), trauma surgery (p = 0.049), and an ASA score >2 (p = 0.011). Overall infection incidence in this cohort reached 4%, with trauma cases, smoking, hypertension, and an ASA score >2 independently linked to deep infections. Surgeons should be cognizant of these risk factors when managing prophylactic antibiotic regimens for patients.

In orthopaedic surgery, as well as other areas in medicine, it is common for a surgical technique to carry the original authors' name describing the procedure. The Judet family represents a unique history, since several orthopaedic procedures are known as "Judet's technique". The aim of this historic review is to outline the genealogy of the orthopaedic arm of the Judet family, while crediting each surgical procedure to the specific family member that described the technique.

INTRODUCTION: Chronic plantar ulcers in leprosy are lesions resulting from motor and sensory alterations caused by Mycobacterium leprae. They are lesions refractory to conventional dressings and present high recurrence rates. OBJECTIVE: To evaluate the epidemiological clinical profile of patients with chronic plantar ulcers associated with bony prominences in the lesion bed and to evaluate the efficacy of orthopedic surgical treatment of these lesions. METHODS: This is a descriptive and analytical retrospective study with the evaluation of medical records of patients undergoing surgical treatment of chronic plantar ulcers from 2008 to 2018. The surgical technique applied consisted of corrective resection of bone prominences and the primary closure of the lesion with bipediculated local flap. RESULTS: 234 patients were submitted to surgery, 55.1% male with an average age of 69.5 years old. Of these, 82.9% were illiterate; and 88.5% with open lesions over 10 years. After surgical treatment, total wound healing occurred in an average time of 12 weeks. The variables that contributed to shorter healing time were: Patients' lower age group; regular use of orthopedic shoes and insoles and dressings performed by nurse aides in health units before surgery. Obesity was the factor that correlated with the delay of healing time. CONCLUSION: A higher incidence was observed in males and male and female illiterate patients. The regular use of shoes and insoles and dressings performed by nurse aides in health units contributed to shorter postoperative healing time. Orthopedic surgical treatment with corrective resection of bony prominences proved to be an efficient therapeutic method for the closure of chronic plantar ulcers. It is a reproducible method, justifying the importance of the orthopedic surgeon in the context of the multidisciplinary team to cope with these complex lesions.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To perform a systematic review and meta-analysis to identify if intraoperative or postoperative differences in outcomes exist between orthopedic and neurological spine surgeons. SUMMARY OF BACKGROUND DATA: Spine surgeons may become board certified through orthopedic surgery or neurosurgical residency training, and recent literature has compared surgical outcomes between surgeons based on residency training background with conflicting results. MATERIALS AND METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a search of PubMed and Scopus databases was conducted and included articles comparing outcomes between orthopedic spine surgeons and neurosurgeons. The Newcastle-Ottawa scale was used to determine the quality of studies. Forest plots were generated using mean differences (MD) for continuous variables and odds ratios (OR) for binomial variables, and 95% CI was reported. RESULTS: Of 615 search term results, 16 studies were identified for inclusion. Evaluation of the studies found no differences in readmission rates [OR, ref: orthopedics: 0.99 (95% CI: 0.901, 1.09); I2 = 80%], overall complication rates [OR, ref: orthopedics: 1.03 (95% CI: 0.97, 1.10); I2 = 70%], reoperation rates [OR, ref: orthopedics: 0.91 (95% CI: 0.82, 1.00); I2 = 86%], or overall length of hospital stay between orthopedic spine surgeons and neurosurgeons [MD: -0.19 days (95% CI: -0.38, 0.00); I2 = 98%]. However, neurosurgeons ordered a significantly lower rate of postoperative blood transfusions [OR, ref: orthopedics: 0.49 (95% CI: 0.41, 0.57); I2 = 75%] while orthopedic spine surgeons had shorter operative times [MD: 14.28 minutes, (95% CI: 8.07, 20.49), I2 = 97%]. CONCLUSIONS: Although there is significant data heterogeneity, our meta-analysis found that neurosurgeons and orthopedic spine surgeons have similar readmission, complication, and reoperation rates regardless of the type of spine surgery performed.

BACKGROUND: Opioid abuse has been an increasing problem since the 1990s. With over 47,000 opioid related deaths recorded in 2017 alone, concerns have been raised regarding the dangers of introducing opioids perioperatively to patients undergoing major surgeries. OBJECTIVES: The present study proposes to examine the frequency, amount, and trends in post-operative opioid consumption in patients undergoing orthopedic surgical procedures. STUDY DESIGN: This was a randomized, retrospective questionnaire-based study. SETTING: Patients who underwent any type of orthopedic surgery at the University of Pennsylvania Presbyterian Hospital from 1/1/2018 to 3/12/2019 were randomly selected and called during the summer of 2019. METHODS: In this retrospective questionnaire-based study, 828 patients were called by telephone in the summer of 2019. These patients were asked a variety of questions involving opioid consumption behavior post-surgery. The study ended after receiving responses from 200 patients. RESULTS: Nineteen (9.5%) patients reported positively for experiencing euphoria while taking opioids post-surgery. Of the 200 patients contacted, 6 patients (3%) reported switching to marijuana instead of opioids. Thirty-eight (19%) patients preferred to take no opioids at all post-surgery, and one patient was found to have given their prescription to a family member or friend. Twenty-one patients (10.5%) were found to have been taking opioids for non-severe pain. Blacks and whites were the most common racial demographics, making up 84 and 109 of the totals, respectively. The odds ratios for all of the predictors showed that the relative risk for opioid misuse was higher for black patients than white patients (OR = 3.034). There was no relationship between the intra- and post-operative opioid administration and long-term opioid misuse. LIMITATIONS: Patients are self-selected and had the option to opt out of the study when contacted. Some patients may not have been available to answer the phone when our study was being conducted. This study was only conducted for orthopedic patients and for patients who received surgery at the University of Pennsylvania Presbyterian Hospital, thus affecting the demographics for our research. CONCLUSIONS: Prescription opioid misuse is more common among the black population. The total opioid consumption is frequently lower than the quantity prescribed. Patients frequently use opioids even though they feel that pain is insufficient to deserve such an intervention. Euphoria is experienced by a significant number of patients taking prescription opioids Often patients do not take any opioids, although they had prescriptions.

OBJECTIVE: This study aimed at evaluating the effect of thrombophilia on the risk of venous thromboembolism (VTE) in patients undergoing any type of orthopedic surgery. BACKGROUND: Patients undergoing orthopedic surgery are at high risk for VTE. Although patients with thrombophilia have an increased risk of VTE, it is currently unclear whether there is a synergetic effect in patients with thrombophilia who undergo orthopedic surgery. METHODS: Data from a large population-based case-control study (the Multiple Environmental and Genetic Assessment [MEGA] of risk factors for venous thrombosis study) were used. Odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for age, sex, and body mass index (BMI) (ORadj) were calculated for patients undergoing any orthopedic intervention. RESULTS: Of 4721 cases and 5638 controls, 263 cases and 94 controls underwent orthopedic surgery. Patients who had any orthopedic intervention in the year before the index date were at higher risk of VTE (ORadj 3.7; 95% CI, 2.9-4.8) than those who did not undergo any orthopedic surgery. There was an additionally increased risk in patients with factor V Leiden (OR 17.5, 95% CI, 4.1-73.6), non-O blood group (OR 11.2; 95% CI, 3.4-34.0), or elevated plasma levels of factor VIII (OR 18.6; 95% CI, 7.4-46.9) all relative to patients without these defects, not undergoing orthopedic surgery. CONCLUSIONS: Patients with factor V Leiden, high levels of factor VIII, or blood group non-O were found to have a high risk of VTE after orthopedic surgery. Identification of these patients may enable individualized thromboprophylactic treatment to efficiently reduce VTE risk.
