RESUMEN
OBJECTIVES: To report early results of the "Internal Joint Stabilizer of the Elbow" (IJS-E) in the treatment of terrible triad injuries and other unstable traumatic elbow dislocations. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Seventeen patients with traumatic elbow instability treated with IJS-E over a 2-year period; 7 of whom sustained terrible triad-type injuries. INTERVENTIONS: Open reduction internal fixation with the "IJS-E". MAIN OUTCOME MEASURES: Elbow stability and arc of motion were assessed radiographically and clinically. Disabilities of the Arm, Shoulder and Hand scores were collected by telephone. RESULTS: All elbows were radiographically stable at the time of IJS-E removal. Mean time of follow-up was 9 months from index operation (range, 2.5-24 months). Mean elbow arc of motion was restored to flexion-extension 92 degrees (range, 5-125; SD, 31 degrees) and forearm pronation-supination 139 degrees (range, 0-180; SD, 48 degrees). Mean Disabilities of the Arm, Shoulder and Hand score was 22.2 (range, 7.5-45.7; SD, 13.3) for patients at least 1 month from surgery on the ipsilateral extremity. Five patients (30%) developed complications, and -2 (12%) required revision for implant failure. CONCLUSIONS: The IJS-E offered reliable treatment of traumatic elbow instability, particularly terrible triad-type injuries. It permited early range of motion and was effective in restoring elbow stability. We believe that the use of this relatively novel system should be further explored. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Percutaneous techniques are commonly used to treat pelvic ring disruptions but are not mainstream for fixation of pubic symphysis disruption worldwide. Potential advantages include less blood loss and lower risk of surgical site infection, especially in the morbidly obese or multiply injured patient. This study was performed to describe the clinical and radiographic outcomes of patients after percutaneous reduction and screw fixation of pubic symphysis disruption and to evaluate the preliminary safety and efficacy of this technique and its appropriateness for further study as an alternative method of fixation. METHODS: A retrospective review was performed to identify all patients who underwent percutaneous fixation of pubic symphysis disruption by two surgeons at an academic Level I trauma center over a 3-year period. Patients underwent percutaneous reduction and fixation of the pubic symphysis using 1 or 2 fully or partially threaded 5.5, 6.5, or 7.3 mm cannulated screws in a transverse or oblique configuration. Associated posterior ring injuries were fixed with trans-sacral and/or iliosacral screws. The primary outcome of interest was loss of reduction, defined as symphysis distance greater than 15 mm measured on final AP pelvis radiograph. Secondary outcomes collected by chart review were operative time, blood loss, vascular or urologic injury, sexual dysfunction, infection, implant loosening or breakage, and revision surgery. RESULTS: Twelve patients met criteria and primary and secondary outcomes were collected. Mean clinical and radiographic follow-up were 15 months each. One patient lost reduction. Mean operative time and blood loss were 124 min and 29 cc, respectively. No vascular or urologic injuries occurred. Two patients reported sexual dysfunction. No patients became infected or required revision surgery. Four patients underwent implant removal. Seventeen additional patients were excluded due to short follow-up and limited outcomes were collected. Two of these patients lost reduction. Three underwent implant removal. CONCLUSION: These data support percutaneous reduction and screw fixation of pubic symphysis disruption as a potentially safe and effective method of treatment that warrants further investigation.
