Biological sex differences in pain response and functional outcomes after orthopedic surgery procedures: a scoping review

Background/Objective: Post-operative pain is frequently experienced by patients following orthopedic surgery procedures despite improved surgical technology and anesthesia techniques. The intensity of postoperative pain is multifactorial and biological sex is a key component of pain analysis. In this review article, the authors examine the impact of biological sex on post-operative pain scores and surgical outcomes following orthopedic surgery procedures. Methods: A keyword-based search of the National Library of Medicine and the National Center for Biotechnology Information was utilized for this review. Through our literature search we identified 56 articles related to the impact of sex on post-operative pain. These studies were then tabulated and analyzed in detail to provide data for this review article. Results: There are a variety of factors that influence surgical outcomes in orthopedics including age, comorbidities, and biological sex. The reviewed studies found that women report higher pain scores in the initial 6 wk post-operative period after total joint arthroplasty, upper extremity surgery, spine surgery, and general orthopedic surgery. Female sex was also associated with higher opioid consumption following surgery. In addition, men tend to have better surgical outcomes following total joint arthroplasty, upper extremity procedures, and spine surgery. Discussion/Conclusion: Biological differences including hormones, anatomy, and psychosocial factors influence post-operative pain differences between sexes. Little data is available on orthopedic surgery post-operative pain scores between the sexes and therefore further research is needed. Biological sex must be considered when evaluating patient wellness following orthopedic surgery procedures.

Revision Endoscopic Carpal Tunnel Release: An Update on Technique and Outcomes.

Carpal tunnel release is among the most frequently conducted upper extremity procedures. While it typically provides patients with improved sensation, decreased pain, and improved function, a small percentage of cases require revision due to failed initial surgery. Consequently, adoption of endoscopic techniques for carpal tunnel revision procedures is beginning to be explored. A retrospective analysis was conducted of postoperative clinical visits and patient-reported outcome measures for four patients who had undergone five endoscopic revision carpal tunnel release procedures (one patient had bilateral disease). All five cases had symptoms consistent with recurrent carpal tunnel syndrome. One hundred percent (5 of 5) of cases resulted in patients reporting symptom improvement. Postoperative clinical visits and improved patient-reported outcome measures (QuickDash, PROMIS Upper Extremity, VAS Pain, PSEQ, PHQ, and Surgery Satisfaction) scores from baseline to 6 weeks demonstrated successful postoperative function and symptom resolution. Five of five cases resulted in patients resuming normal activities without restrictions within 1-5 weeks, with an average of 3.4 weeks. Preliminary findings suggest the endoscopic revision procedure may be safe and effective for patients with recurrent carpal tunnel syndrome, extending the indications to include scars proximal to the wrist crease. Moreover, this minimally invasive procedure facilitates a transition back to normal activities and avoids incisions on weight-bearing surfaces of the palm. Adopting endoscopic revision may reduce the need for prolonged postoperative care and physical therapy. However, due to the limited sample size of five patients, further investigation with larger cohorts is warranted to confirm these observations.

Decreasing Opioid Addiction and Diversion Using Behavioral Economics Applied Through a Digital Engagement Solution: Protocol for a Randomized Controlled Trial.

Despite strong and growing interest in ending the ongoing opioid health crisis, there has been limited success in reducing the prevalence of opioid addiction and the number of deaths associated with opioid overdoses. Further, 1 explanation for this is that existing interventions target those who are opiate-dependent but do not prevent opioid-naïve patients from becoming addicted. Leveraging behavioral economics at the patient level could help patients successfully use, discontinue, and dispose of their opioid medications in an acute pain setting. The primary goal of this project is to evaluate the effect of the 3 versions of the Opioid Management for You (OPY) tool on measures of opioid use relative to the standard of care by leveraging a pragmatic randomized controlled trial (RCT). A team of researchers from the Center for Learning Health System Sciences (CLHSS) at the University of Minnesota partnered with M Health Fairview to design, build, and test the 3 versions of the OPY tool: social influence, precommitment, and testimonial version. The tool is being built using the Epic Care Companion (Epic Inc) platform and interacts with the patient through their existing MyChart (Epic Systems Corporation) personal health record account, and Epic patient portal, accessed through a phone app or the MyChart website. We have demonstrated feasibility with pilot data of the social influence version of the OPY app by targeting our pilot to a specific cohort of patients undergoing upper-extremity procedures. This study will use a group sequential RCT design to test the impact of this important health system initiative. Patients who meet OPY inclusion criteria will be stratified into low, intermediate, and high risk of opiate use based on their type of surgery. This study is being funded and supported by the CLHSS Rapid Prospective Evaluation and Digital Technology Innovation Programs, and M Health Fairview. Support and coordination provided by CLHSS include the structure of engagement, survey development, data collection, statistical analysis, and dissemination. The project was initially started in August 2022. The pilot was launched in February 2023 and is still running, with the data last counted in August 2023. The actual RCT is planned to start by early 2024. Through this RCT, we will test our hypothesis that patient opioid use and diverted prescription opioid availability can both be improved by information delivery applied through a behavioral economics lens via sending nudges directly to the opioid users through their personal health record.

Tissue Augmentation Techniques in the Management of Ligamentous Knee Injuries.

Despite early reports of high failure rates in knee ligament repair techniques resulting in favor of reconstruction, newer advances in surgical technology have shifted the attention back to repair with the addition of various tissue augmentation techniques. Ligament repair preserves proprioceptors in the native ligament and avoids autograft tendon harvest, minimizing the complications associated with donor site ruptures in reconstruction techniques. Tissue augmentation has been successfully used in knee ligamentous and tendon repair procedures, as well as in some upper extremity procedures. This study provides a clinical update on the surgical techniques, biomechanics, and outcomes with the application of various tissue augmentation techniques in the ligaments surrounding the knee joint.

Resident involvement in hand and upper extremity surgery: An analysis of 30-day complications

BackgroundRotations in hand and upper extremity surgery are a core component of the Orthopaedic and Plastic Surgery resident training curriculums. This study compares short-term outcomes in hand and upper extremity procedures with and without resident involvement. MethodsThe National Surgical Quality Improvement Program database was queried from years 2005–2012 for all procedures distal to the shoulder. Patients were stratified based on whether a resident scrubbed for the procedure. Outcome measures were 30-day mortality, reoperation rate, minor complications, major complications, and length of stay (LOS). Chi-squared tests were used to determine significant variables. Significant variables were included in a binomial multivariate logistic regression model. ResultsA total of 7697 patients were included in the study. Of those, 4509 (59 %) had no resident, and 3188 (41 %) had a resident. Patients with resident involvement were less likely to be Caucasian, ASA classification 3 or higher, and outpatient. Cohorts were similar with respect to age, sex, and emergent status. Operative time was 15 min longer in resident cases. Work relative value units were higher in resident cases. In the multivariate logistic regression model, resident involvement had no statistically significant impact on LOS, mortality, reoperation rate, minor complications, or major complications. Subgroup analysis showed increased odds of superficial surgical site infections in resident cases, although this was statistically insignificant (OR 1.35, p = 0.24). ConclusionsHand and upper extremity procedures with resident involvement do not have any increase in overall adverse short-term outcomes. In appropriately selected cases, residents can participate without compromising patient safety.

Adherence to Complication Reporting for Randomized Controlled Trials Contained in Clinical Practice Guidelines for the Management of Carpal Tunnel Syndrome

Randomized controlled trials (RCTs) are frequently used in creating recommendations contained within clinical practice guidelines (CPGs). However, investigations outside of hand surgery have reported that RCTs within CPGs infrequently report complications and harms-related data. Our purpose was to assess adherence to complication reporting and harms-related outcomes contained in the Consolidated Standards for Reporting (CONSORT) Extension of Harms and Standards for Reporting of Diagnostic Accuracy Studies (STARD) reporting checklists for RCTs within the American Academy of Orthopaedic Surgery (AAOS) CPGs for carpal tunnel syndrome (CTS). We identified all RCTs within the AAOS CTS CPGs. All therapeutic RCTs and diagnostic studies were included. We used the CONSORT Harms Checklist criteria to assess adherence to the reporting of adverse events for therapeutic RCTs and the STARD criteria to assess the diagnostic accuracy of the articles. We defined adequate compliance as adherence to ≥50% of the checklist items. We identified 82 therapeutic RCTs and 90 diagnostic accuracy articles within the AAOS CTS CPG. For therapeutic RCTs, we found that the average compliance with the published checklists was 19%. For diagnostic studies, the average compliance with checklists was found to be 55%. Eleven therapeutic RCTs (13%) and 60 diagnostic studies (67%) were determined to have adequate compliance for the CONSORT and STARD checklists, respectively. Randomized controlled trials in the AAOS CPGs for CTS have low compliance with the CONSORT Extension for Harms Checklist. Although the overall adherence to the items published in the STARD statement for diagnostic accuracy evaluation remains higher, future efforts should be made to improve the adherence rates to both checklists. Improved standardization of complication reporting may aid in comparing outcomes across multiple clinical investigations of upper-extremity procedures.

Effectiveness of Brachial Plexus Blocks in Obesity: Secondary Analysis of Randomized Controlled Trial.

Brachial plexus block for hand and upper extremity procedures in the obese presents a unique set of technical challenges. The authors examined how obesity affects procedural success, quality of anesthesia, and patient satisfaction. Secondary analysis of a randomized control trial comparing the retroclavicular versus supraclavicular brachial plexus block for distal upper extremity surgery was conducted. Patients were randomized to supraclavicular or retroclavicular brachial plexus block groups in the original trial. In this study, the authors dichotomized patients by obesity to compare differences in outcomes. Sixteen of 117 patients (13.7%) were obese. The groups were statistically well balanced in terms of baseline and operative variables. Obese patients had increased imaging time 2.7 minutes (95% confidence interval [CI], 1.44-3.92) versus 1.9 minutes (95% CI, 1.64-2.16), P value = .05; needling time 6.6 minutes (95% CI, 5.17-7.95) versus 5.8 minutes (95% CI, 5.04-5.74), P = .02; and procedure time 9.3 minutes (95% CI, 7.04-11.46) versus 7.3 minutes (95% CI, 6.79-7.79), P = .01. Block success and complications were not statistically significant. The visual analog scores during the block, at 2 hours, and 24 hours after were not statistically different. Patient satisfaction score among obese patients was 9.1 (95% CI, 8.6-9.6) versus 9.2 (95% CI, 9.1-9.4), P = .63. Findings from this trial suggest that despite an increased procedural difficulty, the use of both supraclavicular and retroclavicular brachial plexus blocks is associated with comparable quality of anesthesia, similar complication profile, equal opioid requirements, and similar patient satisfaction in the obese.

Survey of blood flow restriction therapy for rehabilitation in Sports Medicine patients

Blood flow restriction (BFR) therapy has demonstrated benefits across a spectrum of musculoskeletal injuries, including improved strength, endurance, function, and reduction in pain perception. There is, however, no standardized application of BFR therapy among orthopaedic surgeons within the United States (US). The indication and protocol for BFR therapy vary significantly across providers in the US. An online survey of 21 multiple-choice questions was sent to 3,281 surgeons listed on a large orthopaedic registry. A cross-sectional study was performed on all surgeons who successfully completed the questionnaire. Surgeons were queried on current or planned use of BFR, indications, contraindications, and peri-operative and non-operative management of sports-related injuries. Overall, 250 physicians completed the survey, with 149 (59.8%) reporting current BFR use and 75.2% initiating use in the last 1-5 years. Most protocols (78.8%) utilize the modality 2-3 times per week while 15.9% use it only once weekly. Anterior cruciate ligament reconstruction (ACLR) rehabilitation was the most reported indication for initiating BFR therapy (95.7%) along with medial patellofemoral ligament reconstruction (70.2%), multiligamentous knee reconstruction (68.8%), meniscus repair (62.4%), collateral ligament reconstruction (50.4%), Achilles tendon repairs (30.5%), and meniscectomy (27%). Only 36.5% reported using BFR after upper extremity procedures, such as distal biceps repair (19.7%), ulnar collateral ligament elbow reconstruction (17%), rotator cuff (16.8%), and shoulder labrum repair (15.3%). For non-operative injuries, 65.8% of surgeons utilized BFR. Of those not currently using BFR therapy, 33.3% intended to implement its use in the future. BFR therapy has increased in popularity with most physicians implementing its use in the last 5 years. BFR was commonly utilized after ACLR. BFR allows light-load resistance to simulate high-intensity resistance training. This study describes US orthopaedic surgeons' common practice patterns and patient populations that utilize BFR therapy.

Elective Hand Surgery Is Delayed among Private Insurance Holders.

Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

Publicly Disclosed Pricing for Common Upper-Extremity Procedures: An Analysis of Hospital Chargemasters.

American hospitals are required to provide price transparency data (known as a chargemaster) for medical services, which is intended to allow consumers to accurately estimate the cost of medical services. Our purpose was to identify hospital compliance in publishing chargemaster documents and to assess the price information published for common upper-extremity services and procedures. We performed a cross-sectional analysis of publicly available chargemaster data from 122 hospitals, which included the top-20-ranked Honor Roll hospitals from US News and World Report and 2 top-ranked hospitals from each state. Chargemaster files were accessed for each hospital, and price information was recorded for 10 common upper-extremity procedures including radiographs, injections, and surgeries. Mean procedural prices were compared between academic and nonacademic hospitals. Chargemaster files were able to be accessed for 107 (88%) of 122 institutions. Price estimates for imaging studies were more frequently reported (73%) than those of procedures (23%-41%). With 50 hospitals reporting a price estimate, carpal tunnel injection was the most frequently reported procedure, whereas trigger finger release was the least frequently reported (41% and 23%, respectively). Wide price ranges were noted, with mean charges for a total shoulder arthroplasty listed as US $51 723 (range, US $247-US $364 024). Mean prices between academic and nonacademic hospital systems were similar. While most (88%) of the included hospitals have been compliant with publishing their price transparency files, price estimates for common upper-extremity procedures and imaging studies are inconsistently reported and, when present, demonstrate high levels of price variability between and within hospital systems.

Hand and Upper Extremity Surgical Site Infection Rates Associated With Perioperative Corticosteroid Injection: A Review of the Literature.

Corticosteroid injection (CSI) has a relatively high benefit-to-risk ratio and is commonly administered to treat musculoskeletal conditions. However, perioperative CSI has been associated with an increased risk of postoperative infection. The literature suggests delaying surgery after CSI to minimize the risk of postoperative infection. We review the literature to summarize the most current knowledge on the association between perioperative CSI and infection rates for different hand and upper extremity procedures. Two independent reviewers conducted a literature search using PubMed and Web of Science databases (through October 1, 2022). The database searches used were (((injection) AND (infection)) AND (risk)) AND ((hand) OR (wrist) OR (elbow) OR (shoulder)). English-language articles were screened for infection rates associated with CSI given temporally around upper extremity surgery, focusing between 6 months preoperatively and 1 month postoperatively. Nineteen articles including database queries and retrospective case-control or cohort studies were used after screening 465 articles. Most infection rates were increased in hand, wrist, elbow, and shoulder surgery between 3 months preoperatively and 1 month postoperatively. Intraoperative injection during elbow arthroscopy demonstrated increased infection rate relative to other upper extremity surgeries. Corticosteroid injection increased the risk of infection temporally around upper extremity surgeries; however, CSI provides benefits. The consensus regarding CSI timeline perioperatively has yet to be determined. The evidence supports an increased benefit-to-risk ratio when giving corticosteroids greater than 3 months preoperatively and greater than 1 month postoperatively for most upper extremity procedures, with relative contraindications within 1 month of upper extremity surgery.

Radiation dose assessment to patients undergoing radiological X-ray procedures of upper extremity

All exposures to diagnostic X-rays need to be justified and optimized in terms of benefit and risk; one of the basic requirements for such requirement is the patient dose assessment. The aim of this study was to evaluate the radiation doses to patient during upper extremities examinations. The research was conducted in two public hospitals of Kebbi State with a total of 150 adult patients. Entrance skin dose estimation was conducted on normal X-ray examinations. ESD was estimated by using mathematical model which are the common indirect method. The results of ESD were used to estimate proposed diagnostic reference levels. In this work, the X-ray radiation exposure parameters were recorded for forearm, upper arms and hands X-ray procedures of one hundred and fifty (150) male and female patients underwent X-ray examination in SMH and FMC. The recorded parameters for X-rays examinations were converted to entrance surface dose (ESD) through mathematical approach. It can be concluded that radiation dose and radiation dose level estimation is essential to prevent health risks of X-ray exposures during the radiological procedures.

Medicare Reimbursement in Hand and Upper Extremity Procedures: A 20-Year Analysis.

Concern exists that Medicare physician fees for procedures have decreased over the past 20 years. The Centers for Medicare & Medicaid Services (CMS) is set to re-evaluate these physician fees in the near future for concern that these procedures are overvalued. Our study sought to analyze trends in Medicare reimbursement rates from 2000 to 2019 for the top 20 most billed hand and upper extremity surgical procedures at our institution. The financial database of a single academic tertiary care center was queried to identify the Current Procedural Terminology codes most frequently utilized in orthopedic hand and upper extremity procedures in 2019. The Physician Fee Schedule Look-Up Tool from the CMS was queried for annual physician fee data. Monetary data were adjusted for inflation using the consumer price index of Urban Research Series (CPI-U-RS) and expressed in 2019 constant US dollars (USD). The average annual and total percent change in reimbursement were calculated via linear regression for all procedures (P < .05). Accounting for inflation, the total average physician reimbursement decreased by 20.9% from 2000 to 2019, with 12 of 20 codes decreasing by more than 20%. The greatest decrease pertained to arthrodesis of the wrist at 33.9%. Upon linear regression, all procedures were found to decrease annually, with arthrodesis of the wrist decreasing by an average of 2.3% annually over this period. Over the past 2 decades, physician reimbursement for hand and upper extremity procedures has significantly decreased.

A Helpful Assistant for Disinfection in Hand Surgery Procedures: The LocArm Holder.

Although there is no consensus regarding the best skin disinfection technique, whatever antiseptic solution is used, the "prep and drape" portion of most upper extremity procedures requires the presence of at least one operative room assistant or scrub nurse to elevate and hold the hand and forearm. Nonetheless, especially in a busy hand surgery practice and during fast procedures, an operative room assistant or scrub nurse are frequently not available leading to a reduced time efficiency between procedures. This article describes an innovative easy-to-use and hands-free device that helps the surgeon during disinfection of the skin and the setup of the surgical field by keeping elevated the upper limb with respect for tissues. The development of the surgical arm holder starts from three easily available and washable thermoplastic splint sheets 40 × 60cm with 2.5cm thickness. The final device measures 40 × 25 × 15cm and is placed underneath the proximal third of the humerus in order to keep the upper limb suspended at about 10-15cm from the operating table. A retrospective analysis of the "surgical malpractice claims" and institutional non-conformities registered in the period 2011-2020 was conducted in our Hospital looking for bone or soft tissue complications related to the use of the device. Three thousand one hundred eighty-seven surgical procedures were performed between 2011 and 2020 using this device. The retrospective analysis of all "surgical malpractice claims" showed no skin lesions, no neurological complications (such as neuroapraxia), no need for secondary bone procedures or interference with the draping process. Our device proved to be a low-cost, easy to use and alternative solution helping surgeons during the disinfection phase, improving hospital pre-operative flow and reducing the need for other staff members to be engaged in holding the upper limb in the operating room.

Multiple Opioid Prescribers During the Perioperative Period Increases Opioid Consumption Following Upper Extremity Surgery: A Multicenter Analysis.

BackgroundOpioid prescribing practices have been an area of interest for orthopedic surgeons in the wake of the opioid epidemic. Previous studies have investigated the effects of a multitude of patient-specific risk factors on prolonged opioid use postoperatively. However, to date, there is a lack of studies examining the effects of multiple prescribers during the perioperative period and their potential contribution to prolonged opioid use postoperatively. This study aimed to investigate if multiple unique opioid prescribers perioperatively predispose patients to prolonged opioid use following upper extremity surgery. Second, we compared opioid prescribing patterns among different medical specialties.MethodologyThis retrospective study was conducted at three academic institutions. Between April 30, 2018, and August 30, 2019, 634 consecutive patients who underwent one of three upper extremity procedures were included in the analysis: carpal tunnel release (CTR), basal joint arthroplasty (BJA), or distal radius fracture open reduction and internal fixation (DRF ORIF). Prescription information was collected using the state Prescription Drug Monitoring Program (PDMP) online database from a period of three months preoperatively to six months postoperatively. A Google search was performed to group prescriptions by medical specialty. Dependent outcomes included whether patients filled an additional opioid prescription postoperatively and prolonged opioid use (defined as opioid use three to six months postoperatively).ResultsIn total, 634 patients were identified, including 276 CTRs, 217 DRF ORIFs, and 141 BJAs. This consisted of 196 males (30.9%) and 438 females (69.1%) with an average age of 59.4 years (SD: 14.7 years). By six months postoperatively, 191 (30.1%) patients filled an additional opioid prescription, and 89 (14.0%) experienced prolonged opioid use. In total, 235 (37.1%) patients had more than one unique opioid prescriber during the study period (average 2.5 prescribers). Patients with more than one unique opioid prescriber were significantly more likely to have received overlapping opioid prescriptions (15.7% vs. 0.8%, p<.001), to have filled an additional opioid prescription postoperatively (63.8% vs 10.3%, p<.001), and to have experienced prolonged opioid use postoperatively (35.3% vs 1.5%, p<.001) compared to patients with only one opioid prescriber. Patients with multiple unique prescribers filled more opioid prescriptions compared to those with a single prescriber (2.8 refills vs 1.8 refills, p=.035). Within six months postoperatively, 71.4% of opioid refills were written by non-orthopedic providers. Opioid refills written by non-orthopedic prescribers were written for a significantly greater number of pills (68.4 vs. 27.9, p<.001), for a longer duration (22.2 vs. 6.2 days, p<.001), and for larger total morphine milligram equivalents per prescription (831.4 vs. 169.8, p<.001) compared to those written by orthopedic prescribers.ConclusionsPatients with multiple unique opioid prescribers during the perioperative period are at a higher risk for prolonged opioid use postoperatively. Non-orthopedic providers were the highest prescribers of opioids postoperatively, and they prescribed significantly larger and longer prescriptions. Our findings highlight the value of utilizing PDMP databases to help curtail opioid overprescription and potential adverse opioid-related outcomes following upper extremity surgery.

The Impact of Resident Involvement on Outcomes and Costs in Elective Hand and Upper Extremity Surgery

The purpose of this study was to assess the impact of resident involvement on periprocedural outcomes and costs after common procedures performed at an academic hand surgical practice. A retrospective review was performed in all patients undergoing 7 common elective upper extremity procedures between January 2008 and December 2018: carpal tunnel release, distal radius open reduction and internal fixation (ORIF), trigger finger release, thumb carpometacarpal arthroplasty, phalanx closed reduction and percutaneous pinning, cubital tunnel release, and olecranon ORIF. The medical record was reviewed to determine the impact of surgical assistants (resident, fellow, or physician assistant) on periprocedural outcomes, periprocedural costs, and 1-year postoperative outcomes. The involvement of surgical trainees operating under direct supervision was compared with the entire operation performed by the attending surgeon with a physician assistant present. A total of 396 procedures met the inclusion criteria. Analysis of the whole study sample revealed low rates of intraoperative complications, wound complications, medical complications, readmissions, and mortality. Subgroup analysis of carpal tunnel releases revealed significantly greater tourniquet times for residents compared with physician assistants (7 ± 2 min, 6 ± 1 min), as well as longer overall operating room times for residents compared to fellows or physician assistants (17 ± 5 min, 13 ± 3 min, 12 ± 3 min). Operating room times for distal radius ORIF were significantly greater among residents compared to fellows or physician assistants (68 ± 19 min, 57 ± 17 min, 56 ± 14 min). There were no differences in any other perioperative metrics or periprocedural costs for the trigger finger release or cubital tunnel release cohorts. Resident involvement in select upper extremity procedures can lengthen operative times but does not have an impact on blood loss or operating room costs. Surgeons should be aware that having a resident assistant slightly increases operative times in elective hand surgery.

Revision of Carpal Tunnel Surgery.

Carpal tunnel release is one of the most commonly performed upper extremity procedures. The majority of patients experience significant improvement or resolution of their symptoms. However, a small but important subset of patients will experience the failure of their initial surgery. These patients can be grouped into persistent, recurrent, and new symptom categories. The approach to these patients starts with a thorough clinical examination and is supplemented with electrodiagnostic studies. The step-wise surgical management of revision carpal tunnel surgery consists of the proximal exploration of the median nerve, Guyon’s release with neurolysis, the rerelease of the transverse retinaculum, evaluation of the nerve injury, treatment of secondary sites of compression, and potential ancillary procedures. The approach and management of failed carpal tunnel release are reviewed in this article.

Does the Nice Knot Offer Less Elongation Than the Modified Prusik Knot? An In Vitro Study in Cadaver Quadriceps Tendons.

ACL graft-suture fixation can be constructed with needle or needleless techniques. Needleless techniques have the advantage of decreased injury, preparation time, and cost. The Nice knot is common among upper extremity procedures, and has been shown to have higher load to failure and less elongation compared with other double loop knots; however, there are no studies that have looked at its use for ACL graft-suture construct to determine whether it offers less elongation relative to other needleless techniques. In a cadaver quadriceps tendon model, we asked: (1) Does the Nice knot have less elongation than the Prusik knot? (2) Does the Nice knot have increased peak load and stiffness compared with the Prusik knot? (3) What were the modes of failure of each knot? Sixteen quadriceps tendon grafts were harvested from 16 cadaver knee specimens. The median (range) age of the donors was 80 years (70 to 96) and included three male and five female donors. Eight grafts were prepared with the Prusik knot and eight with the Nice knot using a braided polyblend suture. The graft-suture constructs were mounted in a materials testing machine and subjected to a tensile loading protocol beginning with pretensioning of three cycles from 0 to 100 N at 1 Hz followed by a constant load of 50 N for 1 minute then cyclic loading of 200 cycles from 50 to 200 N at 1 Hz. The constructs were loaded to failure as the final step of the loading protocol. Elongations of the construct after each loading step, peak load, stiffness, and graft cross-sectional area were compared. Construct elongations (median [IQR]) for the Nice knot were lower than that of the Prusik knot after pretensioning (4.4 mm [0.8] versus 5.7 mm [1.4]; p = 0.02), preloading (0.6 mm [0.3] versus 1.0 mm [0.3]; p = 0.005), and cyclic loading (7.4 mm [1.4] versus 10.9 mm [2.1]; p = 0.005). Peak load was not different for the Prusik knot construct compared with the Nice knot (334 N [43] versus 312 N [13]; p = 0.08). Stiffness of the Prusik knot construct (103 N/mm [17]) was no different than the Nice knot construct (110 N/mm [13]; p = 0.13). Graft cross-sectional area of the Prusik knot constructs (85 mm2 [35]) were similar to the grafts of the Nice knot constructs (97 mm2 [31]; p = 0.28). Failure mode of the constructs did not differ between groups; it was caused by suture rupture near the knots that secured the free suture ends to the machine and was seen in all 16 tests. The results of this biomechanical study show that the Nice knot construct has similar or greater biomechanical properties compared with the Prusik knot in the graft suture construct, although the magnitude of the differences are not likely to the level of clinical importance. The Nice knot offers an attractive alternative option for needleless ACL graft preparation technique. Future studies should consider comparison to established needle techniques such as Krackow or whipstitch and testing in an intraarticular component in an in vivo model.

Publicly Available Pricing Information for Orthopaedic Upper Extremity Procedures in the United States Lacks Transparency and Consistency Between Major Hospitals

PurposeThe purpose of this study was to assess the price variation of various Medicare severity diagnosis-related group codes for orthopaedic upper extremity procedures for the top 20 orthopaedic hospitals using chargemaster price listings from each hospital.MethodsThe top 20 orthopaedic hospitals in the United States were determined by querying the U.S. News and World Report’s 2020 orthopaedic hospital ranking. This report ranks orthopaedic hospitals according to 4 major domains: outcomes, structure, process/expert opinion, and patient experience. Chargemaster data for the top 20 orthopaedic hospitals was compiled from their websites. Five DRG codes that represented orthopaedic upper extremity procedures were selected, and the pricing information for each was extracted from hospital chargemasters. The median income and cost-of-living index were also compiled for the county that each hospital is located in so that pricing data could be compared to economic measures through regression analysis.ResultsOf the top 20 orthopaedic hospitals, 18 had publicly available pricing information in DRG format on their websites. The DRG code with the highest pricing variability was Hand Injury Procedures (DRG 906; range, $12,832-$253,633). The procedure with the least pricing variability was Hand or Wrist Procedures (DRG 514; range, $24,533-$128,403). Additionally, only the cost of living index was a statistically significant predictor of procedure pricing with a weak correlation.ConclusionHospital chargemaster listings are lacking in 2 major areas: true price transparency and standardization/consistency between hospitals. Chargemaster data are often difficult to find, confusing to patients, and inaccurate. Additionally, the price range for a single DRG code can also vary substantially depending on the hospital. It is possible that hospitals located in areas with high costs of living and median incomes would charge higher prices, but these factors were not found to support this hypothesis.
