Examining the Healthcare and Economic Burden of Gun Violence in a Major US Metropolitan City.

INTRODUCTION: The highest rates of fatal and nonfatal injury due to firearms occur in the Southern United States. This study examined the epidemiology of gunshot wound (GSW) injuries and the association of injury severity with mortality. METHODS: This is a retrospective cross-sectional analysis of 2016 to 2019 data from a mandatory reporting system for all licensed hospitals in Louisiana. Patients aged 18 years and older at the time of hospitalization for GSW were included. Injury severity was measured by the New Injury Severity Score (NISS). Primary outcomes assessed included mortality, length of stay, and total hospital charges. RESULTS: There were 1,709 firearm injuries identified. The patient sample was 83.2% Black and 87.4% male, with a mean age of 34 years. Orthopaedics was the most frequently consulted surgical service. Total hospital visit charges for all GSW-associated care were $262.4 million. The multivariable adjusted odds ratio and 95% confidence interval for mortality associated with a high NISS was 16.32 (8.96, 29.72). CONCLUSION: This study demonstrated the utility of NISS as a predictor of total hospital charges and length of stay, in addition to its well-established role as a predictor of mortality. Epidemiologic trends in GSW pathologies and associated procedures at a major urban trauma center were also reported. LEVEL OF EVIDENCE: Level III, prognostic study.

A Rare Case of a Lisfranc Ligament Transection.

Ligamentous Lisfranc injuries, which mimic a surgical transection are rare. Left untreated or missed, these injuries may result in severe complications including long-term disability. The present case describes a unique mechanism of injury via a sharp object puncture through the plantar surface of the midfoot. It highlights the utility of planning staged procedures to remove a large foreign body object, reports notable intraoperative techniques, and provides a decision management guide for treating this type of injury. Extensive surgical planning may be required when encountering similar cases and knowledge of this may be useful to providers.

Gunshot Wound to the Hip Resulting in a Femoral Head and Acetabulum Fracture Treated With Open Reduction and Internal Fixation and Bipolar Hemiarthroplasty.

Combined fractures of the femoral head and acetabulum due to ballistic injuries are rare injuries, especially in the elderly. We present a case of a 70-year-old female who sustained a gunshot wound to the left hip, resulting in a comminuted femoral head fracture and posterior wall acetabular fracture. She was treated with open reduction and internal fixation of the acetabulum, as well as bipolar hemiarthroplasty for treatment of her femoral head fracture. At her 18-month follow-up visit, the patient was doing well and had no complaints.

A Review of Proximal Tibia Entry Points for Intramedullary Nailing and Validation of The Lateral Parapatellar Approach as Extra-articular.

Tibial shaft fractures are the most common long bone injury and are often treated surgically in an attempt to minimize complications. Although treatment options for tibial shaft fractures vary based on factors including open injury, severity of fracture, and soft tissue status, intramedullary nailing in adults has emerged as the preferred definitive option for stabilization. Therefore, the primary purposes of this review and cadaveric study were to evaluate the entry points for reamed tibial nails and the risks, benefits, and advantages of each approach. Due to concerns of violating the joint capsule and the generalized applicability to everyday practice of the extra-articular lateral parapatellar semi-extended technique, the secondary goal of this manuscript was to evaluate whether an intramedullary tibial nail can be consistently placed extra-articularly using the lateral parapatellar technique described by Kubiak et al. and generalizability to surgeons of varying experience.

Psychological outcomes affect functional outcomes in patients with severe pelvic ring fractures.

PURPOSE: To evaluate the correlation between post-traumatic functional and psychological outcomes in patients with severe pelvic ring injuries. METHODS: Forty-four patients who sustained a completely unstable pelvic ring injury (Tile C, AO/OTA 61C) treated in our institution from 2012 to 2017 were included. A telephone interview was performed in 16 of 44 patients to evaluate pelvic functionality, using the Majeed pelvic score, and psychological evaluation, using Hamilton anxiety and depression rating scales. RESULTS: The mean Injury Severity Score (ISS) was 27 ± 12, and mean GCS at presentation was 13 ± 4. Average time from trauma to interview was 3 years (range, 1-5 years). Mean Majeed pelvic score was 67 ± 22. Majeed sub-scores were pain 19 ± 9, work 10 ± 7, sitting 8 ± 2, sexual intercourse 3 ± 2, walking aids 11 ± 2, gait unaided 9 ± 2, walking distance 8 ± 3. Mean depression and anxiety scores were 16 ± 12 and 17 ± 14, respectively. Significant correlations were observed between functional and psychological outcomes (P < 0.005). Majeed score was negatively correlated with depressive symptoms (r = -0.721, P = 0.002) and anxiety symptoms (r = -0.756, P = 0.001). Depression and anxiety scores were positively correlated (r = 0.945, P < 0.001). CONCLUSION: Lower functional outcomes in patients with Tile C pelvic injuries were correlated with more severe symptoms of depression and anxiety. We recommend that providers consider and treat patients' mental health condition during posttraumatic recovery.

"Nailable" External Fixation of the Tibia: A Novel Technique to Accommodate Delayed Intramedullary Nailing of the Tibia.

External fixation is often used for temporary stabilization of the tibia in several clinical scenarios. Conventional placement of external fixation pins may impede instrumentation with intramedullary nailing, thus requiring pin removal, loss of reduction, and increased operative time during definite fixation. In this article, we describe a strategic pin placement routinely used at our institution in which we create a medially based inverted triangular construct that allows for pins to remain in place during definitive fixation.

The obturator oblique and iliac oblique/outlet views predict most accurately the adequate position of an anterior column acetabular screw.

OBJECTIVE: Percutaneous fixation of the acetabulum is a treatment option for select acetabular fractures. Intra-operative fluoroscopy is required, and despite various described imaging strategies, it is debatable as to which combination of fluoroscopic views provides the most accurate and reliable assessment of screw position. MATERIALS AND METHODS: Using five synthetic pelvic models, an experimental setup was created in which the anterior acetabular columns were instrumented with screws in five distinct trajectories. Five fluoroscopic images were obtained of each model (Pelvic Inlet, Obturator Oblique, Iliac Oblique, Obturator Oblique/Outlet, and Iliac Oblique/Outlet). The images were presented to 32 pelvic and acetabular orthopaedic surgeons, who were asked to draw two conclusions regarding screw position: (1) whether the screw was intra-articular and (2) whether the screw was intraosseous in its distal course through the bony corridor. RESULTS: In the assessment of screw position relative to the hip joint, accuracy of surgeon's response ranged from 52% (iliac oblique/outlet) to 88% (obturator oblique), with surgeon confidence in the interpretation ranging from 60% (pelvic inlet) to 93% (obturator oblique) (P < 0.0001). In the assessment of intraosseous position of the screw, accuracy of surgeon's response ranged from 40% (obturator oblique/outlet) to 79% (iliac oblique/outlet), with surgeon confidence in the interpretation ranging from 66% (iliac oblique) to 88% (pelvic inlet) (P < 0.0001). CONCLUSIONS: The obturator oblique and obturator oblique/outlet views afforded the most accurate and reliable assessment of penetration into the hip joint, and intraosseous position of the screw was most accurately assessed with pelvic inlet and iliac oblique/outlet views. EVIDENCE: Clinical Question.

Occult injuries of the contralateral sacroiliac joint in operatively treated pelvis fractures: incidence, root cause analysis, and proposal of treatment algorithm.

PURPOSE: To determine the most common injury patterns, root cause, and the frequency with which unrecognized contralateral posterior ring injury occurs in patients presenting with surgically treated pelvic fractures. METHODS: The medical records of 73 patients presenting to our level I trauma center (52 male and 21 female patients; mean age 41.8 years; range 18-89 years) with surgically treated pelvic ring fractures between January 1, 2016 and January 1, 2018 were reviewed. Patient demographics, mechanism of injury, associated injuries, imaging prior to binder or external fixation, use of temporary stabilization with pre-peritoneal pelvic packing (PPP) and anterior pelvic external fixation, and fracture pattern were recorded and analyzed to identify independent risk factors contributing to occult contralateral missed posterior ring injury. RESULTS: Occult contralateral pelvic ring injuries occurred in 6/72 patients (8.2% incidence). Pelvis fractures in multiply traumatized patients with associated orthopaedic injuries were associated with higher prevalence of occult contralateral pelvic ring injury (relative risk 1.85, 95% CI 1.13-3.02) as compared to patients with isolated pelvic fractures. CONCLUSIONS: There is an 8.2% incidence of unrecognized contralateral SI joint instability in patients presenting with unstable pelvic ring injuries. Multiply traumatized patients with multiple orthopaedic injuries were an independent risk factor for this injury pattern.

Reduction and temporary stabilization of Tile C pelvic ring injuries using a posteriorly based external fixation system.

Tile C pelvic ring injuries are challenging to manage even in the most experienced hands. The majority of such injuries can be managed using percutaneous reduction techniques, and the posterior ring can be stabilized using percutaneous transiliac-transsacral screw fixation. However, a subgroup of patients present with inadequate bony corridors, significant sacral zone 2 comminution or significant lateral/vertical displacement of the hemipelvis through a complete sacral fracture. Percutaneous strategies in such circumstances can be dangerous. Those patients may benefit from prone positioning and open reduction of the sacral fracture with fixation through tension band plating or lumbo-pelvic fixation. Soft tissue handling is critical, and direct reduction techniques around the sacrum can be difficult due to the complex anatomy and the fragile nature of the sacrum making clamp placement and tightening a challenge. In this paper, we propose a mini-invasive technique of indirect reduction and temporary stabilization, which is soft tissue friendly and permits maintenance of reduction during definitive fixation surgical.

Decreasing Orthopaedic Surgical Site Infections: A New Perioperative Protocol.

BACKGROUND: Little data exist regarding the effects of prophylactic perioperative protocol on reducing surgical site infections. Based on national efforts to prevent SSIs and current evidence in the literature supporting the importance of perioperative prophylaxis, it would seem logical that expanding upon current perioperative protocol would help prevent SSIs. HYPOTHESIS: Multiple variables present risk factors in the development of SSIs in the perioperative period, and optimization of patient management during this time with a series of non-invasive and inexpensive protocols may help prevent SSIs. METHODS: A six-step perioperative protocol was developed and instituted in our community hospital performing mostly outpatient orthopaedic surgical procedures. The rates of SSIs, diagnosed clinically according to the Center of Disease Control SSI criteria by two orthopaedic surgeons performing the operations during postoperative visits, were recorded in all patients whose index procedure fell within a two-month period before and after the introduction of our protocol. Proportions of infections were compared using Pearson's x2 test. RESULTS: There were a total of 312 cases performed by two surgeons; evaluated two months before, 153, and two months after, 159, the implementation of our protocol. The incidence of SSIs before initiation of the protocol was 9.1% n=14; and after implementation, the incidence was zero 14 vs. 0, p less than 0.0001. CONCLUSION: Multiple variables in the perioperative period can contribute to the incidence of SSIs and can be controlled with diligent attention to prophylactic measures such as those presented in this paper. Our new perioperative protocol represents a cost-effective, and noninvasive method to prevent SSIs in an orthopaedic practice.
