In an attempt to reduce opioid prescriptions, the state of California mandated physician participation in the Controlled Substance Utilization Review and Evaluation System (CURES). The goal of this study is to assess whether this intervention led to a change in prescribing habits after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). The 90-day postoperative narcotic use was retrospectively reviewed for 13,382 patients undergoing primary THA and TKA. Patients were divided into pre-CURES and post-CURES cohorts based on date of surgery. Narcotic use was measured in morphine milligram equivalents (MME). There was a 21.3% decrease in postoperative MME post-CURES for patients undergoing THA (756.5±759.5 MME vs 962.00±864.4 MME, P<.0001) and a 19.9% decrease in postoperative MME post-CURES for patients undergoing TKA (1274.3±2707.1 MME vs 1590.6±1725.3 MME, P<.0001). Patients post-CURES required an additional prescription at 2 weeks more frequently compared with patients pre-CURES after THA (27.5% vs 20.5%, P<.001) and TKA (54.2% vs 44.2%, P<.001). Patients undergoing THA had 40.5% and 40.6% less narcotic prescribed compared with patients undergoing TKA pre-CURES and post-CURES (P<.001), respectively. Government guidelines led to a substantial decrease in postoperative MME prescribed after TKA and THA. Patients undergoing THA had a substantially smaller amount of narcotic prescribed than patients undergoing TKA. [Orthopedics. 202x;4x(x):xx-xx.]. [ABSTRACT FROM AUTHOR]

Background: To perform a comprehensive osteologic investigation into trapezium anatomy and investigate the relationship between anatomical factors and osteophyte formation, focusing on sex-specific differences. Methods: This was a cadaveric study involving 1233 trapezia and first metacarpals. Two subgroups ("Control" and "Main Study") were established. The "Control" cohort was used to identify features of the trapezium in specimens devoid of osteophytic change. The prevalence and severity of osteophytic change were investigated in the "Main Study" cohort. Sex differences were specifically assessed. Regression analyses were used to identify factors associated with osteophyte formation. Results: Three discrete surface morphologies exist at the trapezium trapeziometacarpal (TM) facet: heart, quadrilateral, and bean. Controlling for height, men have a larger trapezium TM facet surface area. However, the trapezium assumes the same off-center saddle shape in both sexes. The presence of osteophytes at the basilar joint is a common finding; no differences in osteologic prevalence exist between sexes. The progression of osteophytic change complements the radiographic Eaton-Littler classification system. The trapezium TM facet increases the surface area with incremental osteophyte involvement, with the degree of surface area expansion correlated with increases in the severity of osteophytic change. Increased age, increased surface area, bean morphology, and decreased volar joint depth are associated with more severe osteophyte formation. Conclusions: Anatomical features of the trapezium may contribute to osteophyte development. Although the prevalence of osteophytic disease appears equal between sexes, sex differences exist in some anatomical parameters. These differences may help explain the increased prevalence of symptomatic basilar joint disease in women. [ABSTRACT FROM AUTHOR]
