SUMMARY/CONCLUSIONS:The case of a 60-year-old woman with an impacted, dorsally unstable, displaced intra-articular distal radius fracture with dorsal sheer treated via a dorsal approach. Literature comparing dorsal to volar plating of the distal radius is mixed. Dorsal plating may lead to a greater incidence of implant removal, although radiographic and clinical outcomes seem to be similar. The rates of these complications have reduced over time with the introduction of lower profile locking plates. At 1-year after surgery, the patient demonstrated excellent clinical results with near full and painless range of motion of the wrist. She had full range of motion of thumb and fingers. The dorsal approach to the distal radius offers reliable restoration of functional ability with a low rate of neuropathic complications.

SUMMARY/CONCLUSIONS:Anteromedial coronoid facet fractures typically occur with varus, pronation, and axial forces applied to the elbow. Due in part to the high rate of concomitant lateral collateral ligament (LCL) injuries, untreated anteromedial facet fractures can result in varus and posteromedial rotatory elbow instability. Although small fractures that are not amenable to open reduction and internal fixation can be treated with isolated LCL repair, larger fragments are treated with buttress plating on the anteromedial surface of the coronoid with or without LCL repair. The "over-the-top" approach via a split in the flexor pronator mass is the preferred method of accessing the anteromedial facet. Although data regarding the functional outcomes after operative fixation of the anteromedial facet are limited, observational studies have demonstrated good restoration of elbow stability and motion.

SUMMARY/CONCLUSIONS:This is a case of a 36-year-old female patient presenting with left forearm and wrist pain after a ground-level fall onto her outstretched left hand. Clinical and radiographic evaluation is consistent with a left distal radial shaft fracture with disruption of the distal radioulnar joint, known as a Galeazzi fracture. The purpose of this video is to review the appropriate management of Galeazzi fractures and demonstrate our treatment with this surgical approach.

SUMMARY/CONCLUSIONS:A 46-year-old man presents with left knee bucking 3 months after open reduction and internal fixation of a left knee inferior pole patella fracture. Radiograph and magnetic resonance imaging evaluation reveal displacement and comminution of the inferior pole of the patella confirming failure of the repair. The purpose of this video is to demonstrate the surgical management of failed inferior pole patella fractures using suture anchors for repair of the patella tendon and augmentation with ipsilateral autologous hamstring grafts.

PURPOSE/OBJECTIVE:To assess longer-term (> 5 years) function and outcome in patients treated with anatomic locking plates for proximal humerus fractures. METHODS:This retrospective cohort study was conducted at an urban, academic level 1 trauma center and an orthopedic specialty hospital. Patients treated operatively for proximal humerus fractures with an anatomic locking plate by three orthopedic trauma surgeons and two shoulder surgeons from 2003 to 2015 were reviewed. Patient demographics and injury characteristics, disabilities of the arm, shoulder, and hand (DASH) scores, complications, secondary surgeries, and shoulder range of motion were compared at 1 year and at latest follow-up. RESULTS:Seventy-five of 173 fractures were eligible for analysis. At a minimum 5 years and a mean of 10.0 ± 3.2 years following surgery, DASH scores did not differ from one-year compared to long-term follow-up (16.3 ± 17.4 vs. 15.1 ± 18.2, p = 0.555). Shoulder motion including: active forward flexion (145.5 vs. 151.5 degrees, p = 0.186), internal rotation (T10 vs. T9, p = 0.204), and external rotation measurements (48.4 vs. 57.9, p = 0.074) also did not differ from one year compared to long-term follow-up. By one year, all fractures had healed. After 1-year post-operatively, four patients underwent reoperation, but none for AVN or screw penetration. CONCLUSIONS:Patient-reported functional outcome scores and shoulder range of motion are stable after one year following proximal humerus fracture fixation, and outcomes do not deteriorate thereafter. After one-year, long-term follow-up of fixed proximal humerus fractures may be unnecessary for those without symptoms.

INTRODUCTION/BACKGROUND:The purpose of this study was to evaluate the outcomes of fracture nonunion repair with autogenous iliac crest bone graft (ICBG) under regional anesthesia alone or in combination with other techniques compared to other anesthesia techniques. MATERIALS AND METHODS/METHODS:Overall, 137 patients were identified who underwent ICBG as part of a repair of a long bone fracture nonunion between January 1, 2013 and October 1, 2020. Surgical and anesthetic records were reviewed to classify patients by anesthesia type. General, spinal, and regional anesthetics were used as either the primary anesthetic or as a combination of regional nerve block with general or spinal anesthesia. RESULTS:Administration of regional anesthesia alone or in combination with general or spinal anesthesia (RA) and general or spinal anesthesia only (GS) groups differed in nonunion site distribution (p < 0.001). RA patients were discharged the same day more often than GS patients (30.9% vs 10.0%, p = 0.009) and experienced fewer postoperative complications (p = 0.021). The RA group achieved union sooner than the GS group (by 5.3 ± 3.2 months vs. by 6.8 ± 3.2 months, p = 0.006). Mean morphine equivalent dose was similar between groups (p = 0.23). Regional anesthesia use increased from 2013 to 2020, and same day discharge surgeries simultaneously increased over the same time period. CONCLUSION/CONCLUSIONS:Regional anesthesia use increased in nonunion repair surgery with ICBG from 2013 to 2020. This was associated with an increase in same day discharge, sooner time to union, and decreased postoperative complications. There was not a need for increased opioid prescription in patients that underwent regional anesthesia.

INTRODUCTION/BACKGROUND:Nonunions about the hip occur as a result of femoral neck, intertrochanteric, and certain subtrochanteric fractures. Treatment of a hip fracture nonunion allows for the choice between hip preservation or arthroplasty. The goal of this study was to examine outcomes of hip-preservation nonunion surgery METHODS: Patients who underwent hip preservation for a fracture nonunion of the femoral neck, intertrochanteric and subtrochanteric region to 1 cm below the lesser trochanter over a 10-year period were identified in our nonunion registry. Patients were followed for a minimum of 1 year. Functional outcomes were recorded at follow-up visits. For comparison regarding surgical and hospital outcomes, a group of 23 patients who underwent conversion total hip arthroplasties (cTHA) at the same academic medical center was reviewed. Quality measures such as length of stay, reoperation, and complications were collected. All statistics analysis utilized IBM SPSS 25 (Armonk, NY) RESULTS: Thirty patients who underwent 30 hip-preserving nonunion surgeries were analyzed and compared with 23 cTHA patients. Twenty-nine nonunions went on to heal (average time to union 6.3 months). There was improvement in functional outcome scores for the hip preservation group between baseline and latest follow-up (p < 0.001). Reoperation was required in five patients (17%), including four failed to heal and required a second repair to gain union and one failure that was converted to THA rather than attempt a second nonunion repair. Hip preservation failures were older than those that healed with the index treatment (p = 0.11). There was no significant difference in hospital length of stay, complication rate, or need for reoperation when compared to cTHA group. CONCLUSION/CONCLUSIONS:Hip-preserving surgery is an option that should be considered for patients with nonunion of fractures about the hip. The rates of complications (20.3 vs 17.3%) and reoperation (16.7 vs 17.3%) were equivalent to conversion THA. Excellent outcomes can be achieved in terms of radiographic union and function with hip preservation.

Background The incidence of geriatric hip fractures, respiratory infections (e.g., coronavirus disease 2019 (COVID-19), influenza), and mortality is higher during the fall and winter. The purpose of this study is to assess whether the addition of seasonality to a validated geriatric inpatient mortality risk tool will improve the predictive capacity and risk stratification for geriatric hip fracture patients. We hypothesize that seasonality will improve the predictive capacity. Methodology Between October 2014 and August 2021, 2,421 patients >55-year-old treated for hip fracture were analyzed for demographics, date of presentation, COVID-19 status (for patients after February 2020), and mortality. Patients were grouped by season based on their admission dates into the following four cohorts: fall (September-November), winter (December-February), spring (March-May), and summer (June-August). Patients presenting during the fall/winter and spring/summer were compared. The baseline Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) tool for hip fractures (STTGMAHIP_FX_SCORE) and the seasonality iteration (STTGMA_SEASON) were also compared. Sub-analysis was conducted on 687 patients between February 2020 and August 2021 amid the COVID-19 pandemic. The baseline score (STTGMAHIP_FX_SCORE) and the COVID-19 iteration (STTGMACOVID_ORIGINAL_2020) were modified to include seasonality (STTGMA_COVID/SEASON). Patients were stratified by risk score and compared. The predictive ability of the models was compared using DeLong's test. Results For the overall cohort, patients who presented during the fall/winter had a higher rate of inpatient mortality (2.87% vs. 1.25%, p < 0.01). STTGMA_SEASON improved the predictive capacity for inpatient mortality compared to STTGMAHIP_FX_SCORE but not significantly (0.773 vs. 0.672, p = 0.105) On sub-analysis, regression weighting showed a coefficient of 0.643, with fall and winter having a greater absolute effect size (fall = 2.572, winter = 1.929, spring = 1.286, summer = 0.643). STTGMA_COVID/SEASON improved the predictive capacity for inpatient mortality compared to STTGMAHIP_FX_SCORE (0.882 vs. 0.581, p < 0.01) and STTGMACOVID_ORIGINAL_2020 (0.882 vs. 0.805, p = 0.04). The highest risk quartile contained 89.5% of patients who expired during their index inpatient hospitalization (p < 0.01) and 68.2% of patients who died within 30 days of discharge (p < 0.01). Conclusions Seasonality may play a role in both the incidence and impact of COVID-19 and additional respiratory infections. Including seasonality improves the predictive capacity and risk stratification of the STTGMA tool during the COVID-19 pandemic. This allows for effective triage and closer surveillance of high-risk geriatric hip fracture patients by better accounting for the increased respiratory infection incidence and the associated mortality risk seen during fall and winter.
