Using an Intraoperative Stress Exam to Direct Treatment in Posterior Femoral Head Fracture-Dislocations.

To examine the results of a treatment algorithm incorporating an EUA performed intraoperatively after fixation of the femoral head through a Smith Petersen approach to determine need for posterior wall or capsule repair. Design: Retrospective review. Two Level 1 trauma centers. All acute, traumatic femoral head fractures from posterior hip dislocations treated at participating centers over a 5-year period from 2017-2022. Injuries were classified according to the Pipkin system. The primary outcome was the result of intraoperative EUA performed after femoral head fixation to determine the need for Kocher-Langenbeck exposure for posterior wall and/or capsule fixation. The secondary outcomes included rates of avascular necrosis, heterotopic bone formation, late instability, and conversion to total hip arthroplasty. Studied were 63 males and 22 females with mean age 32.5 (range 18-71). 79 of 85 (92.9%) patients had a stable EUA after fixation of the femoral head through a Smith-Petersen approach. Six (6/85, 7.1%) underwent an additional Kocher-Langenbeck approach for posterior wall or capsule fixation. This included 1 Pipkin I, 1 Pipkin II, and 4 Pipkin IV injuries. Of the Pipkin IV injuries, 51/55 (92.7%) had stable EUA and did not require fixation of their posterior wall. This included 7 patients with wall involvement >20%. Five patients were excluded because of planned fixation of their posterior wall based on preoperative imaging. Of patients with at least 6 months follow up, 16 of 65 (26.4%) developed radiographic evidence of AVN and 21 of 65 (32.3%) evidence of heterotopic bone formation. Seven out of 65 (10.8%) were converted to total hip arthroplasty over the study period. When comparing patients with a single exposure with those with additional KL exposure, they did not vary in their rate of AVN (27.1% vs. 0.0%, P=0.3228), HO formation (30.5% vs. 50.0%, P=0.3788), or conversion to total hip arthroplasty (10.2% vs. 16.7%, P=0.510). This study found residual posterior hip instability after femoral head fixation in patients with and without posterior wall fractures after posterior dislocations. The results of this study support use of an EUA after femoral head fixation to identify residual posterior hip instability in all femoral head fractures from posterior hip dislocations, regardless of Pipkin type. Use of the Smith-Petersen exposure remains a viable surgical option and may be improved with incorporation of an EUA after femoral head fixation. For Pipkin IV injuries with posterior wall fractures with indeterminate stability, an EUA accurately identifies residual instability. Therapeutic Level III.

Is the Orthopaedic Trauma Association-Open Fracture Classification (OTA-OFC) Better than the Gustilo-Anderson Classification at Predicting Fracture-Related Infections in the Tibia?

To investigate and compare the predictive ability of the Orthopaedic Trauma Association Open Fracture Classification (OTA-OFC) and the Gustilo-Anderson classification systems for fracture-related infections (FRI) in patients with open tibia fractures. Design: Retrospective cohort study. Academic trauma center. Patients aged 16 years or older with an operatively treated open tibia fracture (OTA-OTA 41, 42, and 43) between 2010 and 2021. The primary outcome was FRI. The OTA-OFC and the Gustilo-Anderson classifications were compared in their ability to predict FRI. 890 patients (mean age, 43 years [range, 17 to 96]; 75% male) with 912 open tibia fractures were included. 142 (16%) had an infection. The OTA-OFC was not significantly better at predicting FRI than the Gustilo-Anderson classification (area under the curve, 0.66 vs. 0.66; P = 0.89). The Gustilo-Anderson classification was a stronger predictor of FRI than any single OTA-OFC domain, explaining 72% of FRI variance. Only the addition of the OTA-OFC wound contamination domain to Gustilo-Anderson significantly increased the variance explained (72% vs. 84%, P = 0.04). Embedded contamination increased the risk of FRI by approximately 10% as the risk of FRI with embedded contamination was 16% for Type I or IIs, 26% for Type IIIAs, 45% for Type IIIBs, and 46% for Type IIICs. The more complex OTA-OFC system was not better than the Gustilo-Anderson classification system in predicting FRIs in patients with open tibia fractures. Adding embedded wound contamination to the Gustilo-Anderson classification system significantly improved its prognostic ability. Prognostic Level II.

Staged Management for Distal Femur Fractures: Impacts on Reoperation, Stiffness, and Overall Outcomes.

To evaluate the outcomes of staged management with external fixation (ex-fix) before definitive fixation of distal femur fractures. Retrospective cohort. Single Level I Trauma Center. Adults treated operatively between 2004 and 2019 for distal femur fractures (OTA/AO 33A/33C) were identified using Current Procedural Terminology codes. Excluded cases were those with screw only fixation, acute distal femur replacement, 33B fracture pattern, no radiographs available, or did not have 6-months of follow-up. Postoperative complication rates including surgical site infection [SSI], reoperation to promote bone healing, final knee arc of motion <90 degrees, heterotopic ossification formation, and reoperation for stiffness were compared between patients treated with ex-fix before definitive fixation and those not requiring ex-fix. A total of 407 patients were included with a mean follow-up of 27 months [median (IQR) of 12 (7.33) months] (range 6-192 months). Most patients were male (52%) with an average age of 48 (range: 18-92) years. Ex-fix was utilized in 150 (37%) cases and 257 (63%) cases underwent primary definitive fixation. There was no difference in SSI rates ( P = 0.12), final knee arc of motion <90 degrees ( P = 0.51), and reoperation for stiffness ( P = 0.41) between the ex-fix and no ex-fix groups. The 150 patients requiring ex-fix spent an average of 4.2 days (SD 3.3) in the ex-fix before definitive fixation. These patients were further analyzed by comparing the duration of time spent in ex-fix, <4 days (n = 82) and ≥4 days (n = 68). Despite longer time spent in ex-fix before definitive fixation, there was again no significant difference in any of the complication and reoperation rates when comparing the 2 groups, including final knee arc of motion <90 degrees ( P = 0.63), reoperation for stiffness ( P = 1.00), and SSI ( P = 0.79). Ex-fix of distal femur fractures as a means of temporary stabilization before definitive open reduction internal fixation does not increase the risk of complications such as SSI, final knee arc of motion <90 degrees, or reoperations for bone healing or stiffness when compared with single-stage open reduction internal fixation of distal femur fractures. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Medicaid Reimbursement for Common Orthopaedic Trauma Procedures Is 16.0% Less Compared With Medicare With Substantial Variability Between States.

This study seeks to evaluate the variability of Medicaid reimbursement and compare it with Medicare reimbursement using the 20 most commonly billed orthopaedic trauma Current Procedural Terminology (CPT) codes nationwide. The authors anticipate significant variability between states and hypothesize that Medicaid payment will be significantly less than Medicare payment. The top 20 most common orthopaedic trauma surgery procedural codes were identified from a previous analysis performed by Haglin et al. The Centers for Medicare and Medicaid Services Physician Fee Schedule was used to determine reimbursement rates from Medicare, and state Medicaid fee schedules were used to determine reimbursement rates for Medicaid. State Medicaid rates were compared with their corresponding Medicare rates to determine a dollar difference. In addition, the dollar difference for each CPT code was divided by its respective physician relative value unit. This was used to acknowledge the possible variability in the complexity of orthopaedic procedures and the related physician effort. The Medicare Wage Index was used to adjust Medicaid rates based on the cost of living for the state as well. Coefficients of variation were calculated to represent overall variability in Medicaid and Medicare reimbursement rates. The mean reimbursement rates for Medicaid were lower for all 20 procedures compared with Medicare. On average, Medicaid reimbursed 16.0% less than Medicare and 29.6% less when adjusting for cost of living. MCD reimbursed at a higher rate than MCR for all procedures in only 9 states (Alaska, Arizona, Arkansas, Montana, Nebraska, New Jersey, New Mexico, North Dakota, and South Dakota) while 38 states reimbursed at a lower rate than MCR, on average. The coefficient of variation ranged from 0.24 to 0.34 for the Medicaid unadjusted group and from 0.35 to 0.46 for the Medicare Wage Index-adjusted group. By contrast, the Medicare group was consistent at 0.06 for all 20 procedures. The average dollar difference across the 20 CPT codes for Medicaid reimbursement compared with Medicare reimbursement ranged from -$76.89 to -$225.17, and the dollar difference per relative value unit ranged from -$5.96 to -$15.16. This study found a high amount of variation between state Medicaid reimbursement rates and average rates that were significantly lower than Medicare reimbursement rates for the top 20 most used orthopaedic trauma CPT codes as identified by Haglin et al. The discrepancy in reimbursement was increased when Medicaid rates were adjusted for state cost of living. Prognostic, Level III.
