Hospitalist comanagement of patients undergoing orthopaedic surgery is a growing trend across the United States, yet its implementation in an academic tertiary care hospital can be complex and even contentious. Hospitalist comanagement services lead to better identification of at-risk patients, optimization of patient care to prevent adverse events, and streamlining of the admission process, thereby enhancing the overall service efficiency. A successful hospitalist comanagement service includes the identification of service stakeholders and leaders; frequent consensus meetings; a well-defined standardized framework, with goals, program metrics, and unified commands; and an occasional satisfaction assessment to update and improve the program. In this article, we establish a step-by-step protocol for the implementation of a comanagement structure between orthopaedic and hospitalist services at a tertiary care center, outlining specific protocols and workflows for patient care and transfer procedures among various departments, particularly in emergency and postoperative situations.

Background: Delayed wound closure is often used after open reduction and internal fixation (ORIF) of both-bone forearm fractures to reduce the risk of skin necrosis and subsequent infection caused by excessive swelling. However, no studies we are aware of have evaluated factors associated with the use of delayed wound closure after ORIF. Questions/purposes: (1) What proportion of patients undergo delayed wound closure after ORIF of adult both-bone forearm fractures? (2) What factors are associated with delayed wound closure? Methods: The medical records of all patients who underwent ORIF with plate fixation for both-bone fractures by the adult orthopaedic trauma service at our institution were considered potentially eligible for analysis. Between January 2010 and April 2022, we treated 74 patients with ORIF for both-bone forearm fractures. Patients were excluded if they had fractures that were fixed more than 2 weeks from injury (six patients), if their fracture was treated with an intramedullary nail (one patient), or if the patient experienced compartment syndrome preoperatively (one patient). No patients with Gustilo-Anderson Type IIIB and C open fractures were included. Based on these criteria, 89% (66 of 74) of the patients were eligible. No further patients were excluded for loss of follow-up because the primary endpoint was the use of delayed wound closure, which was performed at the time of ORIF. However, one further patient was excluded for having bilateral forearm fractures to ensure that each patient had a single fracture for statistical analysis. Thus, 88% (65 of 74) of patients were included in the analysis. These patients were captured by an electronic medical record search of CPT code 25575. The mean ± SD age was 34 ± 15 years and mean BMI was 28 ± 7 kg/m2. The mean follow-up duration was 4 ± 5 months. The primary endpoint was the use of delayed wound closure, which was determined at the time of definitive fixation if tension-free closure could not be achieved. All surgeons used a volar Henry or modified Henry approach and a dorsal subcutaneous approach to the ulna for ORIF. Univariate logistic regression was used to identify which factors might be associated with delayed wound closure. A multivariable logistic regression analysis was then performed for male gender, open fractures, age, and BMI. Results: Twenty percent (13 of 65) of patients underwent delayed wound closure, 18% (12 of 65) of which occurred in patients who had high-energy injuries and 14% (nine of 65) in patients who had open fractures. Being a man (adjusted odds ratio 9.9 [95% confidence interval 1 to 87]; p = 0.04) was independently associated with delayed wound closure, after adjusting for open fractures, age, and BMI. Conclusion: One of five patients had delayed wound closure after ORIF of both-bone forearm fractures. Being a man was independently associated with greater odds of delayed wound closure. Surgeons should counsel all patients with these fractures about the possibility of delayed wound closure, with particular attention to men with high-energy and open fractures. Future larger-scale studies are necessary to confirm which factors are associated with the use of delayed wound closure in ORIF of both-bone fractures and its effects on fracture healing. Level of Evidence: Level III, therapeutic study. [ABSTRACT FROM AUTHOR]

Case: The expandable intramedullary cage (Conventus Orthopaedics) may treat 3- and 4-part proximal humerus fractures. Cage removal for symptomatic avascular necrosis with humeral head collapse requiring conversion to arthroplasty can be challenging because the cage’s collapsing mechanism becomes inoperable after fracture consolidation. We present cage explantation followed by reverse total shoulder prosthesis placement in a 54-year-old man who underwent plate/cage fixation for a 3-part proximal humerus fracture 10 months earlier. Conclusion: The proximal humeral cage can be extracted safely while preserving adequate bone stock for subsequent arthroplasty. Additional time and exposure are necessary compared with removing a locking plate alone. [ABSTRACT FROM AUTHOR]

Case: Traumatic U- and H-type sacral fractures are often unstable, causing spinopelvic dissociation. We describe a minimally invasive approach that allows percutaneous spinopelvic fixation of unstable H-type sacral fractures using a triangular osteosynthesis construct with S2 alar-iliac screws. We present the case of a patient with traumatic lumbopelvic dissociation who underwent percutaneous S2 alar-iliac and iliosacral screw fixation. Conclusions: Combined percutaneous S2 alar-iliac and iliosacral screw fixation is a safe option for spinopelvic fixation and avoids the soft-tissue compromise of open approaches. The triangular osteosynthesis construct provides adequate pelvic anchor points to allow immediate weight-bearing. [ABSTRACT FROM AUTHOR]

Case: We present a case of a rare low-energy catastrophic failure of a carbon-fiber-reinforced polyetheretherketone tibial intramedullary nail at 10 weeks after placement in a 36-year-old man. We describe our experience with extraction of the device. Conclusion: Carbon-fiber composite implants are approved for clinical use in orthopaedic trauma applications. The rare failure of carbon-fiber implants presents unique challenges because typical extraction techniques cannot be used. With the patient described herein, a terminally threaded guidewire was used to cannulate and extract the distal segment of the nail. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to investigate the relationship between preoperative marijuana use and complications following tibia shaft fracture fixation., Methods: Design: Retrospective cohort study., Setting: Two academic Level I trauma centers., Patient Selection Criteria: Adults age ≥18 years who underwent tibia shaft fracture (OTA/AO 42) fixation from 2014-2022 and had a minimum 3-months postoperative follow-up were included. Patients were considered marijuana users if they had current self-reported marijuana use or a urine toxicology screen positive for cannabinoids documented at initial presentation., Outcome Measures and Comparisons: Bivariate statistics and multivariate regression were used to evaluate the effect of marijuana use on 90-day postoperative thromboembolic and surgical complications, unplanned readmissions, and emergency department (ED) visits. Complications related to fracture union were evaluated in patients with ≥ 6 months follow-up. Multivariate analysis controlled for tobacco use, open fracture, and American Society of Anesthesiologist class ≥ 3., Results: Among 388 patients included in the study, the mean age was 37.6 years (range, 18-90), and most patients were men (66.5%). Ninety-six patients (25%) were identified as marijuana users. Marijuana users were significantly younger (30.5 years vs 40 years, P < .001) and more likely to be male (79% vs 62%, P = .002) and use tobacco currently (73% vs 31%, P < .001) than non-users. Marijuana users experienced higher rates of 90-day surgical complications (11.5% vs 4.8%, P = .030) and deep infection (8.3% vs 2.1%, P = .008) compared with non-users. No significant difference was observed between groups in the rates of thromboembolic complications, nonunion, or delayed union (P > .05). On multivariate analysis, marijuana use was not associated with odds of developing any 90-day surgical complication (OR 2.01; 95% CI 0.83-4.84) or deep infection (OR 2.97; 95% CI 0.95-9.25)., Conclusions: Preoperative marijuana use was not found to be associated with risk of thromboembolic, surgical, or fracture union-related complications in patients undergoing tibia shaft fracture fixation., Level of Evidence: Prognostic Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: To identify the distance between the guidewire for a retrograde pubic ramus screw and critical reproductive structures in men and women., Methods: Twenty hemipelves from 10 fresh-frozen cadavers (pelvis to distal femur) were studied. The mean (±SD) age was 77 ± 6 years for the 5 male cadavers and 71 ± 9 years for the 5 female cadavers. A 2.8-mm guidewire for a cannulated screw was inserted from the parasymphyseal bone using fluoroscopic guidance. The soft tissue was dissected and measurements performed by the first author. In men, we measured the closest distances from the guidewire entry point to the contralateral spermatic cord and corpus cavernosum. In women, we measured the closest distances from the guidewire entry point to the base of the clitoral body and clitoral glans., Results: In male cadavers, mean distances were 8.8 ± 4.2 mm to the spermatic cord and 13 ± 6.7 mm to the corpus cavernosum. The guidewire did not penetrate these structures in any specimen. In female cadavers, mean distances were 12 ± 5.7 mm to the base of the clitoral body and 40 ± 8.2 mm to the clitoral glans. The guidewire also did not penetrate these structures., Conclusions: The contralateral spermatic cord and corpus cavernosum in men and the base of the clitoral body in women are close to the pathway of the retrograde ramus screw guidewire. Careful identification of the entry point and avoidance of multiple attempts of guidewire insertion may reduce the risk of injury to these structures.
