Health care delivery is broken. The cost of care continues to skyrocket and the outcomes most important to patients are often a mystery. Further, care is often delivered via a fee-for-service model where surgeons are rewarded for the quantity, not the quality, of services provided. Such a health care delivery system is not sustainable and does not incentivize stakeholders to focus on the most important element of the health care delivery "puzzle": the patient. Fortunately, we are in the midst of transforming our health care delivery system, with a focus on optimizing the value of care delivery (ie, health outcomes achieved per dollar spent across a full care cycle). In hand surgery, progress has been made as part of this health system evolution. However, there remains much to accomplish. In this article, the authors review the 6 components of a strategic agenda for moving to a high-value health care delivery system for hand surgery, focusing on where we are today and where we need to go from here.

The COVID-19 pandemic had wide-reaching effects on healthcare delivery, including care for hip fractures, a common injury among older adults. This study characterized factors related to surgical timing and outcomes, length-of-stay, and discharge disposition among patients treated for operative hip fractures during the first wave of the COVID-19 pandemic, compared to historical controls. A retrospective, observational cohort study was conducted from 16 March-20 May 2020 with a consecutive series of 64 operative fragility hip fracture patients at three tertiary academic medical centers. Historical controls were matched based on sex, surgical procedure, age, and comorbidities. Primary outcomes included 30-day mortality and time-to-surgery. Secondary outcomes included 30-day postoperative complications, length-of-stay, discharge disposition, and time to obtain a COVID-19 test result. There was no difference in 30-day mortality, complication rates, length-of-stay, anesthesia type, or time-to-surgery, despite a mean time to obtain a final preoperative COVID-19 test result of 17.6 h in the study group. Notably, 23.8% of patients were discharged to home during the COVID-19 pandemic, compared to 4.8% among controls (p = 0.003). On average, patients received surgical care within 48 h of arrival during the COVID-19 pandemic. More patients were discharged to home rather than a facility with no change in complications, suggesting an opportunity for increased discharge to home.

INTRODUCTION: Common anesthesia practice for hand surgery combines a preoperative regional anesthetic and intraoperative monitored anesthesia care (MAC). Despite adequate regional anesthesia, patients may receive doses of intraoperative sedatives which can result in oversedation and potentially avoidable complications. VR could prove to be a valuable tool for patients and providers by distracting the mind from processing noxious stimuli resulting in minimized sedative use and reduced risk of oversedation without negatively impacting patient satisfaction. Our hypothesis was that intraoperative VR use reduces sedative dosing during elective hand surgery without detracting from patient satisfaction as compared to a usual care control.

METHODS: Forty adults undergoing hand surgery were randomized to receive either intraoperative VR in addition to MAC, or usual MAC. Patients in both groups received preoperative regional anesthesia at provider discretion. Intraoperatively, the VR group viewed programming of their choice via a head-mounted display. The primary outcome was intraoperative propofol dose per hour (mg · hr-1). Secondary outcomes included patient reported pain and anxiety, overall satisfaction, functional outcome, and post anesthesia care unit (PACU) length of stay (LOS).

RESULTS: Of the 40 enrolled patients, 34 completed the perioperative portion of the trial. VR group patients received significantly less propofol per hour than the control group (Mean (±SD): 125.3 (±296.0) vs 750.6 (±334.6) mg · hr-1, p<0.001). There were no significant differences between groups in patient reported overall satisfaction, (0-100 scale, Median (IQR) 92 (77-100) vs 100 (100-100), VR vs control, p = 0.087). There were no significant differences between groups in PACU pain scores, perioperative opioid analgesic dose, or in postoperative functional outcome. PACU LOS was significantly decreased in the VR group (53.0 (43.0-72.0) vs 75.0 (57.5-89.0) min, p = 0.018).

CONCLUSION: VR immersion during hand surgery led to significant reductions in intraoperative propofol dose and PACU LOS without negatively impacting key patient reported outcomes.

A simulated fracture model was used to determine the ability of the medial and lateral patellar facet views in detecting magnitudes of articular displacement. Transverse patellar fractures were simulated in ten patients. Medial and lateral translation of the distal fragment were evaluated in 1 mm increments and rotational malalignment along the longitudinal axis of the patella was evaluated in 5 mm increments. In comparison to the true lateral view, the utilization of the medial and lateral patellar facet views considerably improves detection of occult articular surface malreduction.

Background: The objective of this study was to determine whether economic well-being is associated with patient-reported functional outcomes and range of motion 1 year following volar plate fixation of distal radius fracture. Methods: A retrospective study was performed on 200 patients with distal radius fractures treated with volar plate fixation at two Level 1 trauma centres from 2006 to 2017 with 1-year clinical follow-up using a previously published cohort. The economic well-being of patients was assessed using the Distressed Communities Index (DCI). Our outcome variables were patient-reported functional outcomes assessed by QuickDASH score and wrist and forearm range of motion 1 year after surgery. The analysis of variance (ANOVA) test was used to compare outcome variables across pre-established tiers of economic well-being. Results: The mean QuickDASH score at 1 year following distal radius fracture volar plate fixation was 10.8 and ranged from 7.3 to 12.2 across tiers of economic well-being. QuickDASH score and wrist range of motion were not significantly different across all tiers of economic well-being. However, wrist flexion-extension arc at 1 year following surgery was significantly decreased in the economically at-risk group compared with the remaining cohort. Conclusions: Patient-reported functional outcomes 1 year after volar plate fixation of distal radius fracture are similar across tiers of economic well-being. Economically disadvantaged patients are at risk for poorer wrist motion following distal radius fracture surgery, though it is not clear if this difference is clinically significant. Level of Evidence: Level II (Prognostic).

Substantial advances in biotherapeutics are distinctly lacking for musculoskeletal diseases. Musculoskeletal diseases are biomechanically complex and localized, highlighting the need for novel therapies capable of addressing these issues. All frontline treatment options for arthrofibrosis, a debilitating musculoskeletal disease, fail to treat the disease etiology-the accumulation of fibrotic tissue within the joint space. For millions of patients each year, the lack of modern and effective treatment options necessitates surgery in an attempt to regain joint range of motion (ROM) and escape prolonged pain. Human relaxin-2 (RLX), an endogenous peptide hormone with antifibrotic and antifibrogenic activity, is a promising biotherapeutic candidate for musculoskeletal fibrosis. However, RLX has previously faltered through multiple clinical programs because of pharmacokinetic barriers. Here, we describe the design and in vitro characterization of a tailored drug delivery system for the sustained release of RLX. Drug-loaded, polymeric microparticles released RLX over a multiweek time frame without altering peptide structure or bioactivity. In vivo, intraarticular administration of microparticles in rats resulted in prolonged, localized concentrations of RLX with reduced systemic drug exposure. Furthermore, a single injection of RLX-loaded microparticles restored joint ROM and architecture in an atraumatic rat model of arthrofibrosis with clinically derived end points. Finally, confirmation of RLX receptor expression, RXFP1, in multiple human tissues relevant to arthrofibrosis suggests the clinical translational potential of RLX when administered in a sustained and targeted manner.

BACKGROUND: The aim of this study was to develop and validate a finite element (FE) model of the patellofemoral joint to analyze the biomechanics of lateral retinacular release after medial patellofemoral ligament (MPFL) reconstruction in patellar malalignment (increased tibial tubercle-trochlear groove distance (TT-TG)). We hypothesized that lateral retinacular release is not appropriate in patellar instability addressed by MPFL reconstruction due to decreased lateral stability and inappropriate adjustment in patellofemoral contact pressures.

METHODS: A FE in-silico model of the patellofemoral joint was developed and validated. The model was used analyze the effect of lateral retinacular release in association with MPFL reconstruction on patellofemoral contact pressures, contact area, and lateral patellar displacement during knee flexion.

RESULTS: MPFL reconstruction alone results in restoration of patellofemoral contact pressures throughout the entire range of motion (0-90°), mimicking the results from healthy condition. The addition of the lateral retinacular release to the MPFL reconstruction resulted in significant reductions in both patellofemoral contact pressure and contact area. Lateral retinacular release resulted in more lateral patellar displacement during the mid-flexion knee range of motion.

CONCLUSIONS: Combination of lateral retinacular release with MPFL reconstruction in patients with increased TT-TG is not recommended as MPFL reconstruction alone for first-line management of recurrent patellar instability offers a greater biomechanical advantage and restoration of contact forces to resemble that of the healthy knee. The presented biomechanical data outlines the effect of concomitant MPFL reconstruction and lateral retinacular release to help guide surgical planning for patients with recurrent patellar instability due to malalignment.

PURPOSE: Depression has been linked to inferior clinical outcomes among upper extremity patients. It often is challenging to distinguish the symptoms of depression, symptoms of injury, and the interaction between these 2 entities after a patient has been injured. We aimed to study the differences in clinical outcomes after surgical fixation of distal radius fractures between patients with and without a documented history and treatment for depression.

METHODS: All subjects with an isolated, acute distal radius fracture undergoing operative fixation in a 10-year period at a level 1 academic trauma center were screened. Baseline demographic data were collected, and psychiatric history and antidepressant use were recorded and verified with a pharmacy database. Quick Disability of the Arm, Shoulder and Hand (QuickDASH), range of motion, and grip strength were assessed at 12 months after surgery. Multivariable linear regression analysis was used to assess the association of depression with QuickDASH scores at 1 year after surgery.

RESULTS: A total of 211 patients were available for 1-year follow-up, 50 of whom were being treated actively for depression with medication at the time of injury and 161 were without a known diagnosis of, or treatment for, depression. Demographic and injury characteristics were similar between both groups. In a multivariable linear regression model controlling for age, sex, and a history of osteoporosis, active treatment for depression was associated with a slight mean increase in QuickDASH scores, 6.5 (1.3-11.8), 1 year after surgery.

CONCLUSIONS: This study demonstrates a small increase in QuickDASH scores between subjects with a confirmed diagnoses of depression compared with all others after surgical fixation of distal radius fracture at 1-year follow-up. We suggest that a history of depression may portend worse clinical outcomes, although other factors, such as underreporting of depression may influence results.
