RESUMEN
Purpose: High-pressure injection injuries are a rare, and potentially serious, trauma that has historically been associated with high-amputation rates. This study aimed to assess the amputation rates, materials involved, and outcomes at a single institution. Methods: A retrospective analysis of 53 cases at a level-1 trauma center in South Central Texas between 2007 and 2023 was conducted. Patient demographics, injury details, materials injected, surgical interventions, complications, and follow-up data were collected and analyzed. Results: There was an amputation rate of 2.2. Latex-based paints showed more favorable outcomes when compared with grease injections and oil-based paints. There were also fewer reoperations and postoperative complications with latex-based paint injuries. Conclusions: The study signals the need for a re-evaluation of high-pressure injection injury outcomes, highlighting a more optimistic prognosis than previously thought. The evolution of materials in paints, especially latex-based paints, may have been associated with a lower rate of amputation than what was previously reported. Type of study/level of evidence: Prognostic IV.
RESUMEN
CASE: A 34-year-old man was a restrained passenger involved in a high-speed rollover motor vehicle crash. The patient sustained a type 5 AC joint separation, severely comminuted intra-articular glenoid fracture with extension to the coracoid process base, displaced open scapular body fracture, a posterior shoulder dislocation of the glenohumeral joint, and a 2-part proximal humerus fracture. CONCLUSION: To our knowledge, this is the first report describing this injury pattern involving the superior shoulder suspensory complex with an associated open proximal humerus fracture-dislocation.
