Skin Antisepsis before Surgical Fixation of Extremity Fractures.

BACKGROUND: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture). METHODS: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications. RESULTS: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups. CONCLUSIONS: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

Are Orthopaedic Trauma Surgeons Appropriately Compensated for Treating Acetabular Fractures? An Analysis of Operative Times and Relative Value Units.

OBJECTIVES: To evaluate the work relative value units (RVUs) attributed per minute of operative time (wRVU/min) in fixation of acetabular fractures, evaluate surgical factors that influence wRVU/min, and compare wRVU/min with other procedures. DESIGN: Retrospective. SETTING: Level 1 academic center. PATIENT SELECTION CRITERIA: Two hundred fifty-one operative acetabular fractures (62 A, B, C) from 2015 to 2021. OUTCOME MEASURES AND COMPARISONS: Work relative value unit per minute of operative time for each acetabular current procedural terminology (CPT) code. Surgical approach, patient positioning, total room time, and surgeon experience were collected. Comparison wRVU/min were collected from the literature. RESULTS: The mean wRVU per surgical minute for each CPT code was (1) CPT 27226 (isolated wall fracture): 0.091 wRVU/min, (2) CPT 27227 (isolated column or transverse fracture): 0.120 wRVU/min, and (3) CPT 27228 (associated fracture types): 0.120 wRVU/min. Of fractures with single approaches, anterior approaches generated the least wRVU/min (0.091 wRVU/min, P = 0.0001). Average nonsurgical room time was 82.1 minutes. Surgeon experience ranged from 3 to 26 years with operative time decreasing as surgeon experience increased ( P = 0.03). As a comparison, the wRVU/min for primary and revision hip arthroplasty have been reported as 0.26 and 0.249 wRVU/min, respectively. CONCLUSIONS: The wRVUs allocated per minute of operative time for acetabular fractures is less than half of other reported hip procedures and lowest for isolated wall fractures. There was a significant amount of nonsurgical room time that should be accounted for in compensation models. This information should be used to ensure that orthopaedic trauma surgeons are being appropriately supported for managing these fractures. LEVEL OF EVIDENCE: Economic Level IV.

Assessment of sacral osseous fixation pathways for same-level dual transiliac-transsacral screw insertion.

INTRODUCTION: The purpose of this study is to (1) describe a pre-operative planning technique using non-reformatted CT images for insertion of multiple transiliac-transsacral (TI-TS) screws at a single sacral level, (2) define the parameters of a sacral osseous fixation pathway (OFP) that will allow for insertion of two TI-TS screws at a single level, and (3) identify the incidence of sacral OFPs large enough for dual-screw insertion in a representative patient population. METHODS: Retrospective review at a level-1 academic trauma center of a cohort of patients with unstable pelvic injuries treated with two TI-TS screws in the same sacral OFP, and a control cohort of patients without pelvic injuries who had CT scans for other reasons. RESULTS: Thirty-nine patients had two TI-TS screws at S1. Eleven patients, all with dysmorphic osteology, had two TI-TS screws at S2. The average pathway size in the sagittal plane at the level the screws were placed was 17.2 mm in S1 vs 14.4 mm in S2 (p = 0.02). Twenty-one patients (42%) had screws that were intraosseous and 29 (58%) had part of a screw that was juxtaforaminal. No screws were extraosseous. The average OFP size of intraosseous screws was 18.1 mm vs. 15.5 mm for juxtaforaminal screws (p = 0.02). Fourteen millimeters was used as a guide for the lower limit of the OFP for safe dual-screw fixation. Overall, 30% of S1 or S2 pathways were ≥ 14 mm in the control group, with 58% of control patients having at least one of the S1 or S2 pathways ≥ 14 mm. CONCLUSIONS: OFPs ≥ 7.5 mm in the axial plane and 14 mm in the sagittal plane on non-reformatted CT images are large enough for dual-screw fixation at a single sacral level. Overall, 30% of S1 and S2 pathways were ≥ 14 mm and 58% of control patients had an available OFP in at least one sacral level.

A Randomized Trial of Preoperative Practice in a Simulated Operative Environment: 3D Printed Pilon Model Improves Resident Performance.

This study assessed the effect of preoperative planning using a 3D-printed periarticular fracture model on operative performance. A complex pilon fracture was 3D-printed, and a preoperative plan was developed. Orthopaedic surgery residents (n = 20) were randomized into two groups. Group 1 performed routine preoperative planning, while Group 2 was also practiced using a 3D-printed construct before performing fixation of the 3D-printed model. Resident performance was assessed using a video motion capture system and evaluated by blinded reviewers. Three residents (3D group) completed fixation within the allotted 45 minutes. The 3D group had less hand distance traveled for step 1 (89 m vs. 162 m, p = 0.04). The 3D group had better performance on three of the four components and more acceptable reductions (6 vs. 0, p = 0.009). Average global rating scale was higher in the 3D group (3.0 vs. 1.7, p = 0.0095). Use of 3D-printed models for preoperative planning improved resident performance.

Low Adherence to Recommended Guidelines for Open Fracture Antibiotic Prophylaxis.

BACKGROUND: Prompt administration of antibiotics is a critical component of open fracture treatment. Traditional antibiotic recommendations have been a first-generation cephalosporin for Gustilo Type-I and Type-II open fractures, with the addition of an aminoglycoside for Type-III fractures and penicillin for soil contamination. However, concerns over changing bacterial patterns and the side effects of aminoglycosides have led to interest in other regimens. The purpose of the present study was to describe the adherence to current prophylactic antibiotic guidelines. METHODS: We evaluated the antibiotic-prescribing practices of 24 centers in the U.S. and Canada that were participating in 2 randomized controlled trials of skin-preparation solutions for open fractures. A total of 1,234 patients were evaluated. RESULTS: All patients received antibiotics on the day of admission. The most commonly prescribed antibiotic regimen was cefazolin monotherapy (53.6%). Among patients with Type-I and Type-II fractures, there was 61.1% compliance with cefazolin monotherapy. In contrast, only 17.2% of patients with Type-III fractures received the recommended cefazolin and aminoglycoside therapy, with an additional 6.7% receiving piperacillin/tazobactam. CONCLUSIONS: There is moderate adherence to the traditional antibiotic treatment guidelines for Gustilo Type-I and Type-II fractures and low adherence for Type-III fractures. Given the divergence between current practice patterns and prior recommendations, high-quality studies are needed to determine the most appropriate prophylactic protocol.

A Comparison of Exposure Between the Classic and Modified Judet Approaches to the Scapula.

OBJECTIVES: A debate exists over the optimal approach for addressing fractures of the scapula and glenoid. The purpose of this study is to (1) quantify and compare osseous exposure using modified Judet (MJ) and classic Judet (CJ) approaches and (2) assess the change in scapular exposure after triceps release from the inferior glenoid. METHODS: Ten arms on 5 fresh-frozen torsos underwent MJ and CJ approaches. A triceps release was performed following the CJ approach in all specimens. Visual and/or palpable access to relevant surgical landmarks was recorded. Calibrated digital photographs were taken of each approach and analyzed using Image J (NIH, Bethesda, MD) to calculate the surface area of exposed bone. RESULTS: The MJ and CJ approaches exposed 16.8 (±7.58) cm(2) and 98.6 (±25.39) cm(2) of bone, respectively (P < 0.001). The full medial and lateral borders of the scapula were visualized in all approaches with mobilization of the teres minor. Palpable access to the full scapular spine was possible in all cadavers. Although the MJ and CJ approaches only allowed the inferior gleniod neck to be visualized in 1 and 2 specimens, respectively, performing a triceps release provided access to this structure. It also increased the CJ exposure by 12.6 cm(2) (P < 0.001) and allowed palpation of the anterior glenoid margin in 100% of specimens. CONCLUSIONS: In conclusion, the MJ approach allows similar access to landmarks important for reduction and fixation while exposing only 20% of the surface area typically visualized with the CJ approach.

Return to high school- and college-level football after anterior cruciate ligament reconstruction: a Multicenter Orthopaedic Outcomes Network (MOON) cohort study.

BACKGROUND: There is a relative paucity of data regarding the effect of anterior cruciate ligament (ACL) reconstruction on the ability of American high school and collegiate football players to return to play at the same level of competition as before their injury or to progress to play at the next level of competition. PURPOSE: (1) To identify the percentage of high school and collegiate American football players who successfully returned to play at their previous level of competition, (2) to investigate self-reported performance for those players able to return to play or reason(s) for not returning to play, and (3) to elucidate risk factors responsible for players not being able to return to play or not returning to the same level of performance. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This study was a retrospective analysis of prospective patients taken from the Multicenter Orthopaedic Outcomes Network (MOON) cohort who identified football as their primary or secondary sport. Identified patients were then questioned in a structured interview regarding their ACL injury, participation in football before their injury, and factors associated with returning to play. Data were analyzed for player position, concurrent meniscal/ligamentous/chondral injury, surgical technique and graft used for ACL reconstruction, and issues pertaining to timing and ability to return to play. RESULTS: One hundred forty-seven players (including 68 high school and 26 collegiate) met our criteria and were contacted from the 2002 and 2003 MOON cohorts. Return to play rates for all high school and collegiate athletes were similar (63% and 69%, respectively). Based on player perception, 43% of the players were able to return to play at the same self-described performance level. Approximately 27% felt they did not perform at a level attained before their ACL tear, and 30% were unable to return to play at all. Although two thirds of players reported some "other interest" contributing to their decision not to return, at both levels of competition, fear of reinjury or further damage was cited by approximately 50% of the players who did not return to play. Analysis of patient-reported outcome scores at a minimum of 2 years after surgery between patients who returned to play and those who did not demonstrated clinically and statistically significant differences in the International Knee Documentation Committee form, Marx Activity Scale, and Knee injury and Osteoarthritis Outcome Score knee-related quality of life subscale in the collegiate players. Similar clinical differences were not statistically significant in the high school students. Player position did not have a statistically significant effect on the ability to return to play for high school players, and 41% of "skilled" position players and 50% of "nonskilled" position players were able to return to play at the same performance level. CONCLUSION: Return to play percentages for amateur American football players after ACL reconstruction are not as high as would be expected. While technical aspects of ACL reconstruction and the ensuing rehabilitation have been studied extensively, the psychological factors (primarily a fear of reinjury) influencing the ability to return to play after ACL surgery may be underestimated as a critical factor responsible for athletes not returning to play at any level of competition.

Comparative study of short forms of the Tampa Scale for Kinesiophobia: fear of movement in a surgical spine population.

OBJECTIVE: To compare the factor structure of 6 short forms of the Tampa Scale for Kinesiophobia (TSK) by means of confirmatory factor analysis in patients after spinal surgery for degenerative conditions. DESIGN: A cross-sectional survey study. SETTING: University-based surgical clinic. PARTICIPANTS: Adults (N=137) treated by spinal surgery for a degenerative condition (ie, spinal stenosis, spondylosis with or without myelopathy, and spondylolisthesis). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Patients completed the TSK within 3 months of hospital discharge. RESULTS: Confirmatory factor analysis demonstrated that the 2-factor models of the TSK-13 and TSK-11 had a reasonable fit for the data, with internal consistency values >.70. A 1-factor TSK-4 (items 3, 6, 7, and 11) demonstrated an excellent fit for the data, but an adequate internal consistency was not maintained. A poor fit was noted for the 1-factor models of the TSK-13 and TSK-11, and a 4-item TSK (items 1, 2, 9, and 11). CONCLUSIONS: The current study provides further evidence that specific short-form versions of the TSK may be useful for assessing fear of movement in surgical populations. Results support the measurement of fear of movement using the 2-factor, 13- and 11-item versions of the TSK in patients after spinal surgery. A TSK-4 (items 3, 6, 7, and 11) offers a promising alternative to the TSK-13 and TSK-11. However, further research is needed to test the validity and reliability of the TSK-4 in patients undergoing spinal surgery in order to support its use in a clinical environment. Researchers and clinicians interested in a shorter measure of fear of movement should consider using the TSK-11.
