BACKGROUND:The purpose of this study is to determine if a standardized protocol for radial nerve handling during humeral shaft repair reduces the incidence of iatrogenic nerve palsy post operatively. METHODS:Seventy-three patients were identified who underwent acute or reconstructive humeral shaft repair with radial nerve exploration as part of the primary procedure for either humeral shaft fracture or nonunion. All patients exhibited intact radial nerve function pre-operatively. A retrospective chart review and analysis identified patients who developed a secondary radial nerve palsy post-operatively. In each case, the radial nerve was identified and mobilized for protection, regardless of whether the implant necessitated the extensile exposure. RESULTS:Fractures were classified according to AO/OTA guidelines and included 23 Type 12A, 11 Type 12B, and 3 Type 12C. Eight patients had periprosthetic fractures and 28 fractures could not be classified. All patients in the cohort were fixed with locking plates. Surgery was indicated for 36 patients with humeral nonunions and 37 patients with acute humeral shaft fractures. Of the 73 patients, 2 (2.7%) developed radial nerve palsy following surgery, one from the posterior approach and one from the anterolateral approach. Both patients exhibited complete recovery of radial nerve function by 6-month follow-up. No significant differences (p > 0.05) were found in any demographic or surgical details between those with and without radial nerve injury. CONCLUSIONS:Nerve exploration identification and protection leads to a low incidence of transient radial nerve palsy compared to the rate reported in the current literature (2.7% compared to 6-24%). Thus, radial nerve exploration and mobilization should be considered when approaching the humeral shaft for acute fracture and nonunion repairs. LEVEL OF EVIDENCE/METHODS:Level III.

Pain management in the setting of acute and subacute orthopedic trauma can be challenging. Due to the recent focus on the rising opioid epidemic, as well as the adverse side of effects of opioid pain medication, multimodal pain control has become the standard of care for management of orthopedic trauma, particularly during operative fixation. The purpose of this paper is to report on the use of regional anesthesia for surgical intervention of extremity fractures in patients who present following traumatic injury as part of a multimodal pain management protocol. Types of, indications for, and outcomes of both upper and lower extremity peripheral nerve blocks will be reviewed.

CASE:This case describes a 45-year-old man with documented history of untreated bilateral lower extremity psoriasis of equal severity who sustained a closed left tibial-fibular shaft fracture. After operative fixation with an intramedullary nail under a regional nerve block, the left lower extremity circumferential psoriatic plaque resolved throughout 1 year of follow-up with persistence of the contralateral limb disease. CONCLUSION:This case describes a rare outcome for a patient with bilateral leg psoriasis who experienced resolution of psoriatic plaques on the operated leg only after surgery. It is unknown which process: injury, anesthetic, surgery, or fracture healing mediated this unique finding.

INTRODUCTION/BACKGROUND:The purpose of this study was to demonstrate a novel technology used to measure improvements in quality and value of care for treatment of hip fracture patients. METHODS:A novel value-based triaging methodology uses a risk prediction (risk M) and inpatient cost prediction (risk C) algorithm and has been demonstrated to accurately predict high-risk:high-cost episodes of care. Two hundred twenty-nine hip fracture patients from 2014 to 2016 were used to establish baseline length of stay (LOS) and total inpatient cost for each (16) risk:cost quadrants. Two hundred sixty-five patients between 2017 and 2019 with hip fractures were input into the algorithm, and historical LOS and cost for each patient were calculated. Historical values were compared with actual values to determine whether the value of the inpatient episode of care differed from the 2014 to 16 cohort. RESULTS:When evaluated without risk or cost stratification, the mean actual LOS and cost of the baseline cohort compared with the 2017 to 2019 cohort were 8.0 vs 7.5 days (P = 0.43) and $25,446 vs $29,849 (P = 0.15), respectively. This analysis demonstrates that there was only a small change in value of care provided to patients based on LOS/cost over the studied period; however, risk:cost analysis using the novel methodology demonstrated that for select risk:cost quadrants, value of care measured by LOS/cost improved, whereas for others it decreased and for others there was no change. CONCLUSION/CONCLUSIONS:Risk-cost-adjusted analysis of inpatient episodes of care rendered by a value-based triaging methodology provides a robust method of assessing improvements and/or decreases in value-based care when compared with a historical cohort. This methodology provides the tools to both track hospital interventions designed to improve quality and decrease cost as well as determine whether these interventions are effective in improving value.

Introduction: The purpose of this study is to assess the effect of radial head/ neck injury in association with proximal ulna fractures. Methods: Between 2006 and 2020, 107 patients presented to our academic medical center for treatment of a proximal ulna fracture and were enrolled into an IRB-approved database. Radiographs, injury details, and surgical interventions were retrospectively reviewed. Patients were classified as having an isolated proximal ulna fracture (PU), a PU fracture with an associated radial head dislocation (M"“D), or a Monteggia fracture with an associated radial head fracture (M"“V). Clinical and functional outcomes were assessed at follow-up to determine what differences exist between fracture patterns. Statistics were generated using Chi-squared tests for categorical variables and one-way ANOVA tests for numerical variables. Results: While all patients ultimately healed, time to radiographic healing in the PU cohort was shorter at 3.57 ± 1.7 months when compared to the M"“V cohort (5.67 ± 3.8 months) (p < 0.05). At follow-up, patients in the M"“V cohort had poorer elbow pronation and supination when compared to the PU and M"“D cohorts (p < 0.05). Patients within the PU cohort had fewer complications than those in the M"“D and M"“V cohorts (p < 0.05). No differences were found between the three cohorts in regard to rates of reoperation, non-union, wound infection, and nerve compression (p > 0.05). Conclusion: The Monteggia fracture with a concomitant radial head/neck fracture is a more disabling injury pattern when compared to an isolated proximal ulna fracture and Monteggia fracture without an associated radial head/neck fracture.

INTRODUCTION/UNASSIGNED:The purpose is to investigate the incidence of wound complications for total knee arthroplasty (TKA) following tibial plateau open reduction and internal fixation (ORIF). MATERIALS AND METHODS/UNASSIGNED:A prospective arthroplasty registry was queried for patients with CPT codes for primary TKA, tibial plateau ORIF, removal of hardware (ROH), and diagnosis of post-traumatic arthritis. Patients were included if they had undergone tibial plateau ORIF and subsequent TKA. Chart review was performed to obtain demographic, clinical and post-operative information. RESULTS/UNASSIGNED:Twenty-one patients were identified, with average age of 56.23 ± 13.2 years at time of tibial plateau ORIF and 62.91 ± 10.8 years at time of TKA. Seven (33.3%) patients had a tibial plateau fracture-related infection (FRI). Eight (38.1%) patients underwent ROH prior to TKA. Seven (33.3%) patients' TKA incision incorporated the prior plateau incisions. Eight (36.4%) patients developed wound complications following TKA and 5 (23.8%) developed an acute periprosthetic joint infection (PJI) following TKA and had the plateau incision incorporated into the TKA incision. FRI history did not increase the rate of wound complications but did increase the rate of ROH prior to TKA. CONCLUSIONS/UNASSIGNED:Previous FRI involving tibial plateau repair surgery doesn't correlate with PJI after conversion TKA for post traumatic OA. Surgeon-controlled factors such as staged ROH and incision placement can help reduce the rate of wound complications following TKA performed after tibial plateau ORIF.

OBJECTIVES/OBJECTIVE:To (1) determine the ability of the Fracture Risk Assessment Tool (FRAX) to identify the probability of contralateral hip fractures within 2 years of index fracture and (2) identify independent risk factors for a subsequent hip fracture. DESIGN/METHODS:Retrospective. SETTING/METHODS:Urban, academic medical center. PATIENTS/METHODS:This study included a consecutive series of patients treated for unilateral hip fractures between September 2015 and July 2019. RESULTS:Eight hundred thirty-two consecutive patients were included in the analysis with a mean age of 81.2 ± 9.9 years. Thirty-one (3.7%) patients sustained a contralateral hip fracture within 2 years with these patients sustaining the second fracture at a mean 294.1 days ± 197.7 days. The average FRAX score for the entire cohort was 11.9 ± 7.4, and the area under receiving operating characteristic curve (AUROC) for FRAX score was 0.682 (95% CI, 0.596-0.767). Patients in the high-risk FRAX group had a >7% risk of contralateral hip fracture within 2 years. Independent risk factors for contralateral hip fracture risk included patient age 80 years or older and decreasing BMI. CONCLUSIONS:This study demonstrates the strong ability of the FRAX score to triage patients at risk of subsequent contralateral hip fracture within 2 years. In this high-risk FRAX group, patients age older than 80 years and who have decreasing BMI after their index fracture have a 12.5% increased risk of fracture within 2 years which is 4× higher than the current World Health Organization 10-year 3% hip fracture risk standard used to initiate pharmacologic treatment. Therefore, high-risk patients identified using this methodology should be targeted more aggressively with preventative measures including social, medical, and potentially surgical interventions.
