Blunt Abdominopelvic Trauma Complicated by Traumatic Testicular Dislocation in a 19-Year-Old Male Patient: A Case Report.

Case: A 19 year-old male patient presented with testicular dislocation after abdominopelvic trauma. During open reduction and internal fixation, consult to urology was placed after discovering the presence of the intra-abdominal testicle. The testicle was repositioned into the scrotum with orchiopexy, and pelvic fixation was completed with 1 sacroiliac percutaneous screw and pubic symphysis fixation. Postoperative recovery was uneventful, and the patient was discharged home on postoperative day 3.

Conclusion: Testicular dislocation is an uncommon finding after blunt abdominopelvic trauma; hence, it may be overlooked. Prompt diagnosis of testicular dislocation given the need for operative management to preserve testicle viability is crucial.

Level of Supervision and Radiation Exposure of Senior Orthopedic Residents During Surgical Treatment of Proximal Femur Fracture.

Orthopedics 2021 May-Jun;44(3):e402-e406. Epub 2021 May 1.

The sustained use of intraoperative fluoroscopy has led to increased use of minimally invasive surgical techniques, enhanced surgeon proficiency, improved anatomic corrections, reduced patient morbidity, earlier functional recovery, and decreased length of hospital stay. As a result, orthopedic attending surgeons and residents are exposed to more radiation, increasing the risk of cancer and radiation-induced cataracts compared with the general population and those who work in other surgical specialties. The magnitude of radiation exposure depends on the susceptibility of the tissues affected, medical specialty, the position of the C-arm, distance from the radiation beam, level of difficulty of the surgical procedure, surgeon experience, level of resident training, and level of supervision by the attending surgeon. However, little information is available on the effect of supervision level on radiation exposure for orthopedic senior residents. The goal of this study was to investigate whether level of supervision by the attending surgeon affects the radiation exposure of orthopedic senior residents during surgical treatment of proximal femur fracture with cephalomedullary nail fixation. This retrospective cohort study was performed from January 2019 to March 2019. No significant relationship between supervision level and radiation exposure of senior residents was observed. Supervision level does not significantly affect radiation exposure for senior residents; therefore, the implementation of standardized training in radiation safety may be a more essential measure to decrease radiation exposure.

Socioeconomic Factors Influencing Self-reported Outcomes After Posterior Wall Fractures of the Acetabulum: Lessons Learned From a Hispanic Population.

J Am Acad Orthop Surg Glob Res Rev 2020 10 1;4(10):e20.00162. Epub 2020 Oct 1.

From the Orthopedic Surgery Department, University of Puerto Rico (UPR) Medical Sciences Campus, San Juan, Puerto Rico (Dr. Rodríguez-Pérez, Dr. Dávila-Parrilla, Dr. Rivera, Dr. Olivella, Dr. Muñiz, and Dr. Lojo-Sojo), and Pediatric Orthopedic Department, Mayagüez Medical Center, Mayagüez, Puerto Rico (Dr. Ramírez).

Introduction: Demographic and socioeconomic factors are important determinants that may affect patient self-reported outcomes after acetabular fracture surgery. Hispanics, as a minority group, have an increased tendency to suffer demographic and socioeconomic disparities. At the present time, there is scant information regarding their role among Hispanic patients with acetabular fractures. The aim of this study was to investigate whether demographic or socioeconomic factors would affect satisfaction and self-reported functional outcomes in Hispanic patients who endured open reduction and internal fixation (ORIF) of posterior wall fractures of the acetabulum.

Methods: A cross-sectional study of 78 patients with posterior wall fracture of the acetabulum treated with ORIF from 2011 to 2017 was performed. Data from demographics (age, sex, and body mass index [BMI]) and socioeconomic factors (household income, highest educational level achieved, employment status, type of medical insurance, workers' compensation involvement, and injury-related litigation process) were obtained and compared with the Short Musculoskeletal Form Assessment-46 (SMFA-46) questionnaire using a multivariable logistic regression analysis.

Results: Unemployment was the most significant variable associated with dissatisfaction among 15 of the 46 responses of the SMFA-46 (P < 0.048). Patients who had an overweight or obese BMI and had an age of 41 years or older exhibited significantly worse outcomes in 7 of the 46 questions (P < 0.049). Finally, women were less likely to be satisfied in 1 of the 46 questions (P = 0.028). No notable difference was observed in any of the SMFA-46 responses regarding insurance plan, educational level, workers' compensation involvement, and injury-related litigation process.

Discussion: A strong association exists between dissatisfaction after ORIF of posterior wall fractures of the acetabulum and employment status, BMI, and age among the Hispanic population. Addressing socioeconomic factors can be critical to overcome dissatisfaction and improve functional status among Hispanic patients with acetabular fractures.

Anterior tibialis artery pseudoaneurysm after minimally invasive plate osteosynthesis in the proximal tibia: a case report.

J Surg Case Rep 2020 Aug 26;2020(8):rjaa168. Epub 2020 Aug 26.

Orthopaedic Surgery Department, University of Puerto Rico Medical Sciences Campus, San Juan, PR, USA.

Tibial plateau fractures are common fractures associated with high-energy trauma. The treatment of these fractures remains a challenge today. Recent management of fractures has moved from open surgery toward minimally invasive surgery to reduce complications and improve functional outcomes. Nevertheless, such a minimalistic approach makes visualization of neurovascular structures difficult, placing them at risk. We report the case of a 39-year-old male who developed a pseudoaneurysm of the anterior tibial artery following minimally invasive plate osteosynthesis of the right proximal tibia. Diagnosis was made through noninvasive duplex ultrasound and was referred to endovascular service. Understanding of the anatomy of the surgical site is vital to minimize complications. In addition, proper postsurgical patient evaluation is important to monitor the insurgence of such complications.
