Trauma Care

Background: To compare the biomechanical strength of three fixation techniques for the elbow anterior capsule and coronoid process using a synthetic ulna model. We hypothesize that a cortical suture button would be equivalent to the bone tunnel model but inferior to a screw-post construct. Methods: A biomechanical study was conducted using a composite ulna bone model to simulate coronoid process fixation with three techniques: traditional trans-osseous bone tunnel repair, suspensory fixation using a cortical button, and a screw-post construct using a 3.5 mm cortical screw. All constructs were assembled using high-strength suture. Each specimen underwent axial loading on an Instron machine until failure, defined as loss of fixation through the dorsal cortex. Peak ultimate strength was recorded. Statistical analysis was performed using one-way ANOVA and Tukey’s HSD test. Results: The suture button construct demonstrated the highest mean ultimate strength at 490.3 ± 125.2 N, significantly greater than both the bone tunnel (328.8 ± 86.4 N, p < 0.01) and screw-post constructs (273.4 ± 54.5 N, p < 0.001). While the bone tunnel construct exhibited a 20.3% higher strength than the screw-post construct, this difference was not statistically significant (p = 0.13). The screw-post construct showed the least variability in strength to failure but the lowest overall strength. The suture button demonstrated the greatest mechanical strength but also the most variability. Conclusions: Suspensory fixation using a titanium cortical suture button provides significantly greater mechanical strength compared to traditional bone tunnel and screw-post techniques in a synthetic ulna model. While variability was greatest with the suture button construct, its superior load-bearing capacity suggests potential advantages in stabilizing the elbow through anterior capsule and coronoid fracture repair. These findings support further clinical investigation of suture button fixation as a viable technique in complex elbow injuries.

Background/Objectives: Early diagnosis and surgical intervention are critical in upper extremity (UE) compartment syndrome to prevent irreversible muscle necrosis or amputation. Despite its prevalence, there remains limited literature guiding surgical management or predictors of complications. This study aims to characterize risk factors and outcomes following UE fasciotomies. Methods: A 14-year (2010–2024) retrospective review was conducted of adult patients undergoing fasciotomies for UE compartment syndrome at a level 1 trauma center. Exclusion criteria included age <18 years, incomplete records, or fasciotomies not performed for compartment syndrome. Data collected include demographics, injury mechanism, presenting symptoms, and diagnostic methods. Intraoperative details obtained include incision type, number of interventions, closure method, presence of muscle necrosis, and amputation. Results: Fifty-five patients (58 extremities) met the inclusion criteria (median age 42 years; 85% male). Mechanisms included fractures (29.3%), prolonged pressure (“found-down”) (25.9%), vascular injuries (13.8%), ballistic trauma (8.6%), crush (6.9%), and other (15.5%). Common symptoms were pain (72.4%), paresthesias (48.3%), and motor dysfunction (43.1%). Isolated fasciotomy incisions included volar forearm (41.4%), hand (8.6%), dorsal forearm (3.4%), and upper arm (1.7%), with the remaining being combinations thereof. Among the 40 total volar forearm fasciotomies, none developed postoperative dorsal forearm muscle necrosis. Muscle necrosis (19%) was associated with pallor (p = 0.05) and pulselessness (p < 0.001). A prolonged pressure mechanism was associated with increased muscle necrosis (p = 0.02) and amputation (p < 0.001). Meanwhile, the fracture mechanism was associated with decreased muscle necrosis (p < 0.001) and higher DPC rates (p < 0.001). Conclusions: Pain, paresthesias, and motor dysfunction were most common symptoms in UE compartment syndrome; pallor and pulselessness correlated with muscle necrosis, indicating advanced compartment syndrome. The prolonged pressure mechanism was associated with greater muscle necrosis and amputation, while fracture-related mechanisms were associated with decreased muscle necrosis and higher DPC rates.

External fixation is widely used in trauma care for managing bone and soft tissue injuries. These devices are often associated with psychological challenges and are often not followed up with sufficient psychological support for the patient. The specific psychological impact of external fixation following traumatic injuries remains underexplored. This scoping review aimed to synthesize the current literature on the psychological impact of external fixation in trauma patients. A systematic search of CINAHL, Cochrane Library, PsycInfo, PubMed, Scopus, Google Scholar, and EBSCO identified ten studies (2006–2024), from the USA, Europe, Asia, and Oceania to be included based on inclusion criteria of using the device for traumatic injuries (excluding limb lengthening procedures) and assessing psychological outcomes using validated tools. Data extracted included injury type, fixator application, survey type, and mental health outcomes. Common measures included HADS, SF-36/SF-12, PedsQL, CRIES-13, EQ-5D-5L, and patient-reported questionnaires. The findings showed that elevated psychological distress was greatest during early recovery (~1 month). Body image concerns were frequently reported with the fixator in place; however, partial recovery of mental health scores was seen by 12–24 months. These findings emphasize the need for additional research and a greater integration of mental health resources in trauma care protocols involving external fixation.
