Effects of Opioid-Limiting Legislation in the State of Ohio on Opioid Prescriptions After Shoulder Arthroscopy.

Background: Recent studies have shown that legislation regulating opioid prescriptions in the United States has been successful in reducing the morphine milligram equivalent (MME) prescribed after certain orthopaedic procedures. Purpose: To (1) determine the effect of Ohio's legislation limiting opioid prescriptions after shoulder arthroscopy and (2) identify risk factors associated with prolonged opioid use and increased postoperative opioid dosing. Study Design: Cohort study; Level of evidence, 3. Methods: We reviewed the data of patients who underwent shoulder arthroscopy between January 1, 2016, and March 31, 2020. Patients were classified according to the date of legislation passage (August 31, 2017) as before legislation (PRE) or on/after legislation (POST). Patients were also classified based on the number of opioid prescriptions filled within 30 days of surgery as opioid-tolerant (at least 1 prescription) or opioid-naïve (zero prescriptions). We recorded patient characteristics, medical comorbidities, and surgical details, as well as the number of opioid prescriptions, MME per prescription from 30 days preoperatively to 90 days postoperatively, and the number of gamma-aminobutyric acid (GABA) analogues and benzodiazepine prescriptions from 30 days preoperatively to the date of surgery. Differences between cohorts were compared with the Fisher exact test and Wilcoxon test. A covariate-adjusted regression analysis was used to evaluate risk factors associated with increased postoperative opioid dosing. Results: Overall, 279 patients (n = 97 PRE; n = 182 POST; n = 42 opioid-tolerant; n = 237 opioid-naïve) were included in the final analysis. There was a significant reduction in the cumulative MME prescribed in the immediate (0-7 days) postoperative period (PRE, 450 MME vs POST, 315 MME), the first 30 postoperative days (PRE, 590 MME vs POST, 375 MME), and the first 90 postoperative days (PRE, 600 MME vs POST, 420 MME) (P < .001 for all). The opioid-tolerant cohort had higher MME at every time point in the postoperative period (P < .001). Consumption of preoperative opioid (ß = 1682.5; P < .001), benzodiazepine (ß = 468.09; P < .001), and GABA analogue (ß = 251.37; P = .04) was associated with an increase in the cumulative MME prescribed. Conclusion: Opioid prescription-limiting legislation in Ohio significantly reduced the cumulative MME prescribed in the first 30 days postoperatively for both opioid-naïve and opioid-tolerant patients after shoulder arthroscopy. Consumption of opioids, benzodiazepines, and GABA analogues preoperatively was associated with increased postoperative opioid dosage.

Management of Bone Loss and Tunnel Widening in Revision ACL Reconstruction.

➤ Both mechanical and biological factors can contribute to bone loss and tunnel widening following primary anterior cruciate ligament (ACL) reconstruction.➤ Revision ACL surgery success is dependent on graft position, fixation, and biological incorporation.➤ Both 1-stage and 2-stage revision ACL reconstructions can be successful in correctly indicated patients.➤ Potential future solutions may involve the incorporation of biological agents to enhance revision ACL surgery, including the use of bone marrow aspirate concentrate, platelet-rich plasma, and bone morphogenetic protein-2.

Anterior and superior plate positions in diaphyseal clavicle fractures produce similar patient outcomes.

PURPOSE: While diaphyseal clavicle fractures can be treated with plate fixation on either the superior or anteroinferior aspect of the clavicle, the optimal plate position remains controversial. The purpose of this study was to determine if anteroinferior vs. superior plating for clavicle fracture fixation leads to better patient outcomes. METHODS: A retrospective review of patients who sustained clavicle fractures (OTA/AO 15.2) treated with superior or anteroinferior plating at a tertiary Level I trauma center from 2015 to 2021 was performed. The clinical outcomes of clavicle fractures were compared between groups treated with an anterior versus a superior approach via Mann-Whitney U and Chi-squared tests as appropriate to evaluate for differences in outcomes between the two plate positions. RESULTS: A total of 315 diaphyseal clavicle fractures were identified. One hundred and forty patients were excluded due to inadequate follow-up. Of the remaining 175 patients, 25 were treated with an anteroinferior approach (14%) and 150 were treated with a superior approach (86%). There were no differences in age, BMI, tobacco use, or substance use between the two groups (p > 0.05 for all). On univariate analysis, there was no difference in rate of union (p = 0.60), nerve injury (p = 0.60), infection (p = 1.0), implant-related irritation (p = 0.42), implant removal (p = 0.26), or revision (p = 1.0) based on approach. Contoured plates had an association with risk of nerve injury (p = 0.04). CONCLUSION: There are no differences in union, nerve injury, infection, symptomatic implant, or revision rate between anteroinferior and superior clavicle approaches. Plate positioning during diaphyseal clavicle fracture fixation can reasonably be dictated based on surgeon preference and ideal reduction quality.

Biologics, Stem Cells, Growth Factors, Platelet-Rich Plasma, Hemarthrosis, and Scaffolds May Enhance Anterior Cruciate Ligament Surgical Treatment.

Biologics including mesenchymal stem cells (MSCs), growth factors, and platelet-rich plasma may enhance anterior cruciate ligament (ACL) reconstruction and even ACL primary repair. In addition, hemarthrosis after acute ACL injury represents a source of biologic factors. MSCs can differentiate into both fibroblasts and osteoblasts, potentially providing a transition between the ligament or graft and bone. MSCs also produce cytokines and growth factors necessary for cartilage, bone, ligament, and tendon regeneration. MSC sources including bone marrow, synovium, adipose tissue, ACL-remnant, patellar tendon, and umbilical cord. Also, scaffolds may represent a tool for ACL tissue engineering. A scaffold should be porous, which allows cell growth and flow of nutrients and waste, should be biocompatible, and might have mechanical properties that match the native ACL. Scaffolds have the potential to deliver bioactive molecules or stem cells. Synthetic and biologically derived scaffolds are widely available. ACL reconstruction with improved outcome, ACL repair, and ACL tissue engineering are promising goals. LEVEL OF EVIDENCE: Level V, expert opinion.

Interprosthetic Femur Fractures: A Review Article.

➢: The prevalence of interprosthetic femur fractures (IFFs) is rising with the aging population and increased prevalence of total joint arthroplasty. ➢: IFFs have high rates of complications and high associated morbidity and mortality. ➢: The main treatment methods available for IFFs include plate fixation, intramedullary nailing, combined plate fixation and intramedullary nailing, and revision arthroplasty including partial and total femur replacement. ➢: There have been several proposed classification systems and at least 1 proposed treatment algorithm for IFFs; however, there is no consensus. ➢: Whichever treatment option is chosen, goals of surgery should include preservation of blood supply, restoration of length, alignment, rotation, and sufficient stabilization to allow for early mobilization.

Complete Isolated Ruptures of the Distal Biceps Brachii During Athletic Activity: A Systematic Review.

Complete, isolated ruptures of the distal biceps brachii sustained during athletic activities are uncommon. A systematic review of the literature was performed to identify complete distal biceps brachii tears experienced during athletic activities to determine injury prevalence, athletic activities/mechanisms responsible for injury and return to activity timing following operative management. A total of 10 studies, comprising 16 athletes undergoing surgery for 18 cases, were identified. Injuries were predominately associated with weightlifting. Injuries were treated utilizing a single incision in 56% of cases and primary repair performed in 89% of cases. Mean time to return to activity was 4.86 ± 1.14months. Athletes undergoing surgery ≤ 10 days following injury and those undergoing primary repair returned to activity significantly quicker. Isolated tears of the distal biceps remain uncommon during athletic activities, occurring primarily during weightlifting. Return to activity timing was not significantly delayed based on surgical approach, steroid use, or athlete age.

Restoration of the native humeral anatomy during stemless anatomic total shoulder arthroplasty: a radiographic comparison of intramedullary versus freehand resection.

BACKGROUND: During anatomic total shoulder arthroplasty (aTSA), the humeral head can be resected with or without the use of an intramedullary cutting guide, the former referred to as intramedullary (IM) resection and the latter referred to as freehand (FH) resection. Outcomes following aTSA are predicated upon the restoration of the native humeral anatomy, which can be more challenging with stemless implants. To date, no studies have determined which method of humeral head resection is superior in restoring native anatomy. Our purpose was to determine whether FH or IM resection was superior in restoring native anatomy during aTSA with stemless implants. METHODS: A review of all patients who underwent aTSA using the stemless Tornier Simpliciti Shoulder System at two academic institutions by two separate surgeons between January 2017 and June 2020 was performed. One surgeon at one institution performed stemless aTSA using the IM resection technique, while the second surgeon utilized the FH resection technique. Patients were excluded if they underwent surgery for an indication other than glenohumeral osteoarthritis, if they received a short-stem or standard-stem implant, or if they lacked adequate preoperative and postoperative Grashey radiographs. One hundred eleven patients across both institutions (51 IM, 60 FH) were included for the final radiographic assessment. The humeral head height (HH) and neck-shaft angle (NSA) were measured on preoperative and postoperative Grashey radiographs. The centers of rotation (CORs) were measured on postoperative Grashey radiographs. Patients were classified as having acceptable restoration of their native anatomy if the change (Δ) in COR or HH was ≤3 mm and ≤ 5 mm, respectively, or if the postoperative NSA was ≥130°. RESULTS: IM resection had the greatest acceptable restoration of COR (90.2% IM versus 70% FH, P = .009), HH (96.1% IM vs. 63.3% FH, P < .001), and NSA (96.1% IM vs. 78.3% FH, P = .006) relative to FH resection. The mean postoperative NSAs for the IM and FH cohorts were 134.4° (±2.1°) and 133.8° (±5.4°), respectively (P = .208). The mean ΔCORs for the IM and FH groups were 1.2 (±1.5) and 2.3 (±1.2) mm, respectively (P < .001). Finally, the mean ΔHHs for the IM and FH cohorts were 1.7 (±1.4) and 4.4 (±2.9) mm, respectively (P < .001). CONCLUSIONS: Restoration of the native humeral anatomy following stemless aTSA occurred at a significantly higher rate when using IM vs. FH resection.
