Occupational injuries and hazards related to orthopaedic surgery are not well studied, and what is published on this topic is largely based on in vitro or in vivo animal studies. To evaluate the self-reported prevalence of musculoskeletal (MSK) overuse disorders and other conditions among orthopaedic surgeons, especially those performing total hip (THA) or total knee arthroplasty (TKA), and report the factors placing these surgeons at higher risk for occupational health hazards. This was a cross-sectional study of 66 currently practicing orthopaedic surgeons in the Midwestern United States. An online survey was sent to the participants, and all responses were collected anonymously. The survey consisted of 18 multiple-choice questions. Almost 82% of surgeons surveyed had either a musculoskeletal (MSK) overuse disorder, kidney stones, cataracts, infertility, deafness, or a combination of the above. Fifty-three percent of these respondents believed their medical conditions arose due to their job demands ese. A significant proportion (53%) of surgeons believe one or more of their medical conditions developed due to occupational exposure. The custom triflange acetabular implant (CTAI) has been described to address catastrophic pelvic osteolysis, but long-term outcome data is scarce. Revision-free survivorship after revision THA with a CTAI was retrospectively reviewed in seven patients. Mean and median follow-up time were 7.39 (1.61-16.8) years and 7.50 years, respectively. Revision-free survivorship was 85.7% (6/7). One patient underwent revision for recurrent dislocations. All patients were able to ambulate at recent follow-up- 2/7 without assistance. The CTAI is a viable option for patients with catastrophic pelvic osteolysis. There is a high complication rate, but the incidence of revision is low.

The purpose of this study is to determine which patient factors predict two-year postoperative met expectations in a cohort of patients undergoing knee surgery. Additionally, this study aims to measure the association between met expectations and postoperative outcomes. 319 patients undergoing knee surgery at one institution were studied. Patients completed patient-reported outcome questionnaires prior to surgery and again two years postoperatively. Preoperative Expectations and postoperative Met Expectations were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) Expectations domain. The mean Met Expectations score was significantly lower than the preoperative Expectations Score. Worse two-year Met Expectations were associated with older age, higher BMI, greater comorbidities, more previous surgeries, black race, unemployment, lower income, government insurance, Worker's Compensation, smoking, and no injury prior to surgery. Greater Met Expectations were correlated with better scores on all two-year outcome measures as well as greater improvement on most outcome measures. Race, insurance status, function, mental health, and knee pain were found to be independent predictors of Met Expectations. This study identified multiple patient factors and outcome measures that were associated with Met Expectations two years after knee surgery.

With the increasing number of patients undergoing arthroscopic rotator cuff repair (ARCR), postoperative pain control in these patients has become an important issue. We investigated and compared post-operative pain relief with intravenous acetaminophen (IA) and interscalene brachial plexus block (IBPB) after ARCR. This prospective study involved 66 consecutive patients who underwent ARCR in 2019-2020at our hospital. Overall, 23 and 43 shoulders were assigned to the IA and IBPB groups, respectively. We evaluated the visual analog scale (VAS) pain scores at rest, during activity, and at night for the first 72h postoperatively. We compared the results statistically between the groups. A p-value <0.05 was considered statistically significant. VAS scores for night pain in the IBPB group were significantly lower than those in the IA group for the first 24h postoperatively (p=0.017). In contrast, the same scores were significantly lower in the IA group than in the IBPB group at 72h postoperatively (p=0.024). Other scores were not significantly different between the groups. IBPB provides superior night pain control during the first 24h postoperatively, and IA provides superior night pain control at 72h postoperatively. However, there were no significant differences in other pain scores between the two groups. IBPB provides superior night pain control during the first 24 h postoperatively, and IA provides superior night pain control at 72 h postoperatively. However, there were no significant differences in other pain scores between the two groups. We aimed to clarify the iliac anatomy in developmental dysplasia of the hip using three-dimensional computed tomography. The distance between two points along each anatomical portion of the ilium, including the acetabular center, were compared between patients in the dysplasia and control groups. There were no significant differences in the upper part of the ilium between the groups. https://www.selleckchem.com/products/ly333531.html However, three distances that included the acetabular center were significantly shorter in the dysplasia group than in the control group. Our study suggests that bone dysplasia occurs in the ilium near the acetabulum, not in the iliac wings.

Databases were searched according to the Preferred Reporting Items for Systematic Reviews. PD patients had higher wound infections, dislocations, peri-prosthetic fractures, and revision surgery compared to their non-PD counterparts. They also had inferior functional outcomes, and longer and expensive hospital admissions. Dual-mobility (DM) implants had the lowest survival rate. THR in PD patients is associated with significant surgical complications and peri-operative challenges. Despite the use of DM implants to minimize instability, there is insufficient evidence on its effectiveness and long-term survivorship.
