Impending and complete pathologic fractures of the distal humerus are rare complications of metastatic cancer. Surgical treatment aims to quickly restore function and minimize pain. Plate and screw fixation (PSF) is a common method for addressing these lesions, but unlike in orthopaedic trauma, there are no clear guidelines for best management. While dual PSF theoretically provides better support and reduces the chance of reoperation due to tumor progression, single PSF is currently the more common choice. Between March 2008 and September 2021, 35 consecutive patients who underwent PSF for distal humerus metastasis or multiple myeloma were retrospectively reviewed. The proportion of patients who developed various postoperative complications, including infection, nonunion, deep vein thrombosis, tumor progression, and radial nerve palsy, as well as those requiring reoperation, was calculated. Mann-Whitney U test, Pearson's chi-squared, and Fisher's exact test were used to investigate differences between the single and dual PSF groups with statistical significance defined as p ≤ 0.05. There was no significant difference (p = 0.259) in revision rate, although 3 of 21 (14.3 %) single PSF patients required reoperation compared to 0 of 14 (0.0 %) dual PSF patients. The revisions were performed in one patient due to refracture and in two patients due to tumor progression. Although not statistically significant, a larger percentage of single PSF patients developed a postoperative complication compared to dual PSF patients [odds ratio 0.42 (95 % confidence interval 0.071 to 2.5); p = 0.431]. Single PSF did lead to shorter operative time compared to dual PSF [p < 0.001]. Dual PSF is non-inferior to single PSF and potentially results in fewer reoperations and postoperative complications in distal humerus pathologic lesions, although it leads to longer operative time. The current study is limited by small sample size due to the rarity of distal humerus metastatic lesions. [ABSTRACT FROM AUTHOR]

Background. Mandibular fractures due to intentionally violent mechanisms represent a unique subset of facial fractures. The objective of our research is to identify how violence affects patterns of mandibular fractures and their outcomes. Methods. In this institutional review board-approved, retrospective study, we examined our institution's records for adult patients >18 years of age who presented with =1 mandibular fractures from January 2011 to January 2022. Violence was defined as trauma intended to hurt another or self. Demographics, fractures, mechanism, concomitant injuries, treatment, and complications were analyzed with Excel and SPSS statistical software. Results. A total of 692 patients were diagnosed with mandibular fractures, with 323 of these due to violence (47%). These patients of violence (POVs) had an average fracture per patient of 1.6 ± 0.7. The majority (88%) were male and African American (33%), and the average age was 34.3 ± 13.2 years. The most common violent mechanism was a punch (68%). The POVs presented with fewer concomitant injuries, were less likely to be admitted to the intensive care unit, and were more often surgically managed with open reduction than were patients of nonviolence (PONVs) (P < .01). POVs were more likely to have healing complications; though not statistically significant, this population was observed to be frequently lost to follow-up (P = .12). POVs notably had a much higher proportion of hardware exposure among complications than was seen in PONVs (23% vs 9%). Conclusions. Patients with violent fracture mechanisms may tend to be predisposed to more complications compared with patients who have nonviolent fracture mechanisms despite lesser severities due to social determinants of health. Characteristics of this patient subset may tend to cause difficulties in postoperative care and follow-up. Effective discharge instruction communication, patient outreach programs, and homelessness and drug abuse screening in this subset may help reduce healing complications. [ABSTRACT FROM AUTHOR]
