Abstract
Distal radius fractures are common injuries that often require surgical intervention. Commonly, these fractures are fixed using open reduction internal fixation with plating and screws. This often requires a more extensive soft tissue dissection and exposure. In contrast for certain cases, percutaneous headless compression screws may be appropriate. We present a technique for minimally invasive arthroscopic-assisted reduction and percutaneous screw fixation with an extremity traction device. A case is provided to demonstrate the technique as a viable option for the treatment of intra-articular distal radius fractures.

A quality and readability comparison of artificial intelligence and popular health website education materials for common hand surgery procedures. HAND SURGERY & REHABILITATION 2024; 43:101723. [PMID: 38782361 DOI: 10.1016/j.hansur.2024.101723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 05/16/2024] [Accepted: 05/18/2024] [Indexed: 05/25/2024]
Abstract
INTRODUCTION ChatGPT and its application in producing patient education materials for orthopedic hand disorders has not been extensively studied. This study evaluated the quality and readability of educational information pertaining to common hand surgeries from patient education websites and information produced by ChatGPT. METHODS Patient education information for four hand surgeries (carpal tunnel release, trigger finger release, Dupuytren's contracture, and ganglion cyst surgery) was extracted from ChatGPT (at a scientific and fourth-grade reading level), WebMD, and Mayo Clinic. In a blinded and randomized fashion, five fellowship-trained orthopaedic hand surgeons evaluated the quality of information using a modified DISCERN criteria. Readability and reading grade level were assessed using Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) equations. RESULTS The Mayo Clinic website scored higher in terms of quality for carpal tunnel release information (p = 0.004). WebMD scored higher for Dupuytren's contracture release (p < 0.001), ganglion cyst surgery (p = 0.003), and overall quality (p < 0.001). ChatGPT - 4th Grade Reading Level, ChatGPT - Scientific Reading Level, WebMD, and Mayo Clinic written materials on average exceeded recommended reading grade levels (4th-6th grade) by at least four grade levels (10th, 14th, 13th, and 11th grade, respectively). CONCLUSIONS ChatGPT provides inferior education materials compared to patient-friendly websites. When prompted to provide more easily read materials, ChatGPT generates less robust information compared to patient-friendly websites and does not adequately simplify the educational information. ChatGPT has potential to improve the quality and readability of patient education materials but currently, patient-friendly websites provide superior quality at similar reading comprehension levels.

Abstract
Superficial acral fibromyxoma (SAFM) is a rare, slow-growing benign soft tissue tumor that is typically asymptomatic in nature and usually affects the acral regions of the hands and feet. The majority of these lesions are subungual. Excisional biopsy is the primary treatment modality. Despite the distinct clinical and histopathological features, misidentification of this slow-growing tumor persists. This case report contributes to the existing literature by delineating the clinicopathologic features, radiographic and MRI findings, and treatment strategies of SAFM.

Abstract
BACKGROUND Metacarpal fracture fixation using the retrograde intramedullary screw technique can be performed through two different approaches. The mini-open approach requires greater soft tissue dissection but allows for direct visualization of the metacarpal head compared with the percutaneous approach. Our aim was to determine which approach resulted in optimal screw position. METHODS Eighty-one consecutive patients that underwent intramedullary screw fixation for metacarpal fractures from 2016 to 2021 were identified. Patients were treated by 4 fellowship-trained orthopedic hand surgeons who employed the mini-open or percutaneous approach. Postoperative radiographs were reviewed for screw position. RESULTS A total of 81 patients (41 mini-open, 40 percutaneous) were included in this study. There were no significant differences between the two groups in age, sex, hand dominance, or affected digit. Postoperative screw position at first postoperative visit was not significantly different between the two groups on anteroposterior or lateral radiographs. CONCLUSION Postoperative screw position is not significantly different between the mini-open and percutaneous approaches for intramedullary screw fixation of metacarpal fractures. LEVEL OF EVIDENCE Level III, therapeutic.

Abstract
PURPOSE Ligament reconstruction and tendon interposition is a common technique for thumb basal joint arthroplasty. Recently, a variation of this technique, a suture suspensionplasty, has been introduced. The goal of our study was to assess the optimal position of the bone anchor in the thumb metacarpal. We hypothesized that an anchor placed in the radial aspect of the thumb metacarpal base would provide improved stability and resist subsidence more effectively than an ulnar-based thumb anchor. METHODS Eight fresh-frozen cadaver arms were imaged fluoroscopically in anteroposterior and lateral views centered over the thumb carpometacarpal joint before and after trapeziectomy and after the placement of radial-based and ulnar-based bone anchors. The intermetacarpal angle between the thumb and index metacarpals was measured on all images after the application of a standard force. Radial abduction, opposition, subsidence, palmar abduction, and adduction were measured. Subsidence was calculated as the percentage loss of the trapezial space. RESULTS Both radially and ulnarly placed internal brace constructs allowed more radial abduction, opposition, and palmar abduction than the pretrapeziectomy constructs. They both also reduced subsidence by approximately 20% to 29% compared with the posttrapeziectomy constructs. Comparing radial to ulnar constructs, motion and subsidence were similar. CONCLUSIONS There was immediate stability of the thumb with respect to axial load and subsidence after anchor placement, and this was independent of the anchor position. The position of the bone anchor in the thumb metacarpal base did not affect the range of motion. Although the device can limit subsidence, it does not appear to restrict any range of motion of the thumb, irrespective of anchor position. CLINICAL RELEVANCE This cadaver study can help hand surgeons understand the effect of positioning of bone anchors when performing a specific suture suspensionplasty technique.

Abstract
Background Intramedullary screw fixation is a commonly used technique for the management of metacarpal fractures. However, compression across the fracture site can lead to unintentional shortening of the metacarpal. Questions/Purposes Our aim was to evaluate the risk of overshortening with differing intramedullary device designs for fixation of metacarpals. Methods The small finger metacarpal of nine fresh-frozen cadavers were included. A metacarpal neck fracture was simulated with a 5-mm osteotomy. Three different intramedullary screw designs were compared. Each screw was placed in a retrograde fashion into the intramedullary canal and the amount of shortening measured. Screws were reversed and the number of reverse turns with the screwdriver needed to release overshortening were measured. Results The average shortening at the osteotomy site was 2.5 mm. The mean shortening was 80%, 58%, and 12% for the partially threaded screw, fully threaded screw, and threaded nail, respectively. The mean differences of the distance shortened were statistically significant for the threaded nail compared with the partially and fully threaded screws. The partially threaded screw had the most shortening, while the threaded nail provided the least amount of shortening. When the screws were reversed, the screws did not disengage until the screw was fully removed from the osteotomy site. Conclusion The fully threaded nail demonstrates less shortening and possibly minimizes overshortening of fractures compared with partially threaded and fully threaded screw designs. Overshortening cannot be corrected by unscrewing the screw unless completely removed from the distal fragment. Clinical Relevance Orthopaedic surgeons may select intermedullary screws based on the design that is suited for the particular metacarpal fracture pattern.

Abstract
PURPOSE Initially designed to address geographic obstacles to patient care, reliance on telemedicine rapidly increased during the coronavirus pandemic. The purpose of this study was to analyze the proficiency of computer and mobile device usage among a cohort of surgeons and their patients who either used telemedicine or had in-person visits. METHODS We retrospectively identified patients who had an outpatient telemedicine visit (T group), or in-person visit (NT group) with a hand and wrist orthopedic surgeon, between March 2020 and July 2020. These patients and their surgeons were sent the Computer Proficiency Questionnaire (CPQ-12) and the Mobile Device Questionnaire (MDPQ-16) via email. A total of 602 survey responses were collected, 279 of which belonged to patients in the T group and 323 to patients in the NT group. RESULTS The two groups were similar in demographics, including age and sex. Scores on the CPQ-12 and MDPQ-16 did not significantly differ between the two groups. In the patient sample, there was no correlation between CPQ-12 and MDPQ-16 scores and the proportion of telehealth visits. The orthopedic surgeon group also had no observed correlation between the CPQ-12 and MDPQ-16 scores and number or proportion of telemedicine visits. CONCLUSIONS Overall proficiency with computer and mobile devices was not correlated with the likelihood of patients or orthopedic surgeons using telemedicine visits. Patient selection appears to be driven by other factors, which could include limitations in transportation, convenience, and time constraints. CLINICAL RELEVANCE Orthopedic surgeons should continue to offer telehealth visits to their patients regardless of estimated capabilities with electronic devices of both the patient and the surgeon.

Abstract
Excessive posttraumatic scarring in orthopedic tissues, such as joint capsules, ligaments, tendons, muscles, and peripheral nerves, presents a significant medical problem, resulting in pain, restricted joint mobility, and impaired musculoskeletal function. Current treatments for excessive scarring are often ineffective and require the surgical removal of fibrotic tissue, which can aggravate the problem. The primary component of orthopedic scars is collagen I-rich fibrils. Our research team has developed a monoclonal anti-collagen antibody (ACA) that alleviates posttraumatic scarring by inhibiting collagen fibril formation. We previously established the safety and efficacy of ACA in a rabbit-based arthrofibrosis model. In this study, we evaluate the utility of a well-characterized thermoresponsive hydrogel (THG) as a delivery vehicle for ACA to injury sites. Crucial components of the hydrogel included N-isopropylacrylamide, poly(ethylene glycol) diacrylate, and hyaluronic acid. Our investigation focused on in vitro ACA release kinetics, stability, and activity. Additionally, we examined the antigen-binding characteristics of ACA post-release from the THG in an in vivo context. Our preliminary findings suggest that the THG construct exhibits promise as a delivery platform for antibody-based therapeutics to reduce excessive scarring in orthopedic tissues.

Abstract
PURPOSE Both limited-open and percutaneous techniques have been described for retrograde insertion of intramedullary metacarpal screws. The percutaneous approach does not allow direct visualization of the starting point at the metacarpal head. However, it limits soft tissue dissection and expedites the procedure. The purpose of our study was to determine whether percutaneous, retrograde intramedullary screw fixation causes substantial iatrogenic damage to the extensor tendon. We also investigated whether larger sized screws would cause greater tendon injury compared to smaller screws. METHODS Eight fresh frozen cadaver hands were used for percutaneous, retrograde intramedullary screw insertion of the index, long, ring, and small finger metacarpals of each specimen. Three different types of headless compression screws were used: a small fully threaded screw, a large fully threaded screw, and a Herbert-style partially threaded screw. After insertion, dissection was carried down to the screw entry site. Extensor tendon damage was evaluated, including tendon defect size and any irregularities noted in the tendon. RESULTS There was no statistical difference with respect to how frequently a screw perforated the extensor tendons between all four finger metacarpals. Overall, the defect width caused by the screw was minimal, ranging from 0.66 mm to 1.89 mm for all finger and screw types. The large style screw did cause the greatest mean defect width, however, this was not statistically significant. When normalized to total tendon width, the defect was less than 28% of the total tendon width, with an average of 20% for all finger and screw types. Upon gross inspection, there was no fraying or irregularity noted at the screw-tendon insertion site, and it was often difficult to identify the screw entry site through the tendon by direct visualization alone. No tendon ruptures were noted. CONCLUSIONS This study found that percutaneous insertion of a retrograde, intramedullary metacarpal screw causes minimal extensor tendon injury. In contrast to the limited-open approach, the percutaneous technique requires less soft tissue dissection and the possibility of reduced swelling, scarring, and risk of adhesions. Moreover, it has the potential to allow for early functional rehabilitation and reduced operative time. Interestingly, none of the tendons demonstrated fraying or rupture, as one might expect to occur with blind passage of a drill and screw through a tendon. Overall, the percutaneous, retrograde intramedullary screw technique appears to cause minimal iatrogenic injury to the extensor tendon.

Abstract
PURPOSE To evaluate the proximity of the ulnar neurovascular structures to the endoscopic blade during endoscopic carpal tunnel release (CTR). METHODS Ten fresh-frozen cadaver hands were used to perform endoscopic CTR using devices from two manufacturers. The skin was excised from the palm, and the endoscopic carpal tunnel blade was deployed at the distal edge of the transverse carpal ligament (TCL). The blade's proximity to the ulnar neurovascular bundle, deep ulnar motor branch, superficial palmar arch, and median nerve was recorded. Following release of the TCL, the device was turned ulnar to the maximal extent to determine if direct injury to the ulnar neurovascular bundle was possible. RESULTS The average longitudinal distance from the end of the TCL to the superficial palmar arch was 13.3 mm (range, 8.4-20.9) and to the ulnar motor branch was 10.8 mm (range, 4.0-15.0). The average transverse distance from the end of the TCL to the ulnar neurovascular bundle was 5.9 mm (range, 3.1-7.8) and to the median nerve was 3.3 mm (range, 0-6.5). In two of our specimens, the median nerve subluxated volarly over the cutting device. When placing the blade at the distal edge of the TCL, injury to the deep motor branch of the ulnar nerve, ulnar neurovascular bundle, or superficial palmar arch was not possible in any specimens using the tested devices, even when turning the blade directly toward these structures. CONCLUSIONS There is a low likelihood of direct injury to the ulnar neurovascular bundle during endoscopic CTR. CLINICAL RELEVANCE These results suggest that injury to the ulnar neurovascular bundle is unlikely during endoscopic CTR if the distal aspect of the transverse carpal ligament can be clearly identified prior to release. Control of the median nerve is also important to prevent subluxation over the cutting device.

Abstract
There is wide variability in the management of patients on antithrombotic therapy requiring surgery of the hand and wrist. There are no specific guidelines regarding whether to temporarily cease or continue oral anticoagulants and antiplatelet agents. Discontinuation of these medications before surgery can lead to perioperative thromboembolic or ischemic events. On the other hand, continuation can lead to intraoperative or postoperative bleeding complications. This review discusses various anticoagulants and antiplatelet agents with special considerations for their management, analyzes the current literature, summarizes current recommendations, and provides direction for additional research.

Abstract
INTRODUCTION Physical boundaries to access skilled orthotist or hand therapy care may be hindered by multiple factors, such as geography, or availability. This study evaluated the accuracy of fitting a prefabricated wrist splint using an app on a smart device. We hypothesize that remote brace fitting by artificial intelligence (AI) can accurately determine the brace size the patient needs without in-person fitting. METHODS Healthy volunteers were recruited to fit wrist braces. Using 2 standardized calibrated images captured by the smart device, each subject's image was loaded into the machine learning software (AI). Later, hand features were extracted, calibrated, and measured the application, calculated the correct splint size, and compared with the splint chosen by our subjects to improve its own accuracy. As a control (control 1), the subjects independently selected the best brace fit from an array of available splints. Subject selection was recorded and compared with the AI fit splint. As the second method of fitting (control 2), we compared the manufacturer recommended brace size (based on measured wrist circumference and provided sizing chart/insert brochure) with the AI fit splint. RESULTS A total of 54 volunteers were included. Thirty-two splints predicted by the algorithm matched the exact size chosen by each subject yielding 70% accuracy with a standard deviation of 10% ( p < 0.001). The accuracy increased to 90% with 5% standard deviation if the splints were predicted within the next size category. Fit by manufacturer sizing chart was only 33% in agreement with participant selection. CONCLUSION Remote brace fitting using AI prediction model may be an acceptable alternative to current standards because it can accurately predict wrist splint size. As more subjects were analyzed, the AI algorithm became more accurate predicting proper brace fit. In addition, AI fit braces are more than twice as accurate as relying on the manufacturer sizing chart.

Abstract
PURPOSE The purpose of this cadaveric study was to investigate the intrinsic anatomy surrounding the metacarpal head and the relationship between the interosseous-lumbrical junction (ILJ) and transverse metacarpal ligament (TML) as it pertains to saddle deformity-posttraumatic adhesions at the ILJ that cause impingement during intrinsic activation. METHODS Ten fresh frozen cadaveric arms underwent dissections, identifying the intrinsic musculature within the second through fourth webspaces. The TML and ILJ, or "true tendon," were identified. A separate area of nontendinous fibrous tissue identified proximal to the ILJ was referred to as "pseudotendon." Measurements were made within each webspace to identify distances between these structures in full finger extension and intrinsic plus position to assess for changes during simulated motion. RESULTS The true tendon to TML distance progressively decreased toward the ulnar digits. In the intrinsic plus position, the pseudotendon to TML distance was 0 mm at all webspaces for each specimen. When moving from neutral to intrinsic plus, the true tendon to TML distance decreased the most in the third and fourth webspaces compared with the second, consistent with the trend toward a smaller ILJ to TML gap in the ulnar digits. CONCLUSIONS There is a fibrous pseudotendinous region proximal to the ILJ that abuts the TML in the intrinsic plus position, which may cause impingement when inflamed in the setting of saddle syndrome. Furthermore, a decreased ILJ to TML gap in the ulnar digits may be related to an increased predilection for saddle deformity in those areas. CLINICAL RELEVANCE These results suggest that there is a fibrous region present proximal to the ILJ that may be implicated in the pathology of saddle deformity. Furthermore, decreased distances found between the ILJ and TML in vivo may be an explanation for increased occurrence of saddle syndrome in the third and fourth webspaces in clinical practice.

Abstract
PURPOSE Our practice recently implemented a system that enables patients to self-schedule outpatient visits through an online portal. The purpose of this study was to evaluate the appropriateness of self-scheduled appointments in the Hand and Wrist Surgery Division of our practice. METHODS Outpatient visit notes from 128 new patient visits among 18 fellowship-trained hand and upper extremity surgeons were collected; 64 visits were self-scheduled online, and 64 were scheduled using the traditional call center system. The notes were deidentified and divided among 10 hand and upper extremity surgeons, such that each note was reviewed by two different reviewers. The surgeons scored each visit on a scale of 1-10, with 1 representing a completely inappropriate visit for a hand surgeon and 10 representing a completely appropriate visit. Primary diagnoses and treatment plans were recorded, including whether surgery was planned during the visit. The final score for each visit resulted from the average of the two separate scores. The average appropriateness score for all self-scheduled visits was compared with the average score for all traditionally scheduled visits with a two-sample t test. RESULTS The average appropriateness score for self-scheduled visits was 8.4 of 10, with seven visits resulting in a planned surgery (10.9%). Traditionally scheduled visits had an average appropriateness score of 8.4 of 10, with eight visits resulting in a planned surgery (12.5%). The average difference in the scores between reviewers for all visits was 1.7. CONCLUSIONS In our practice, the appropriateness of visits that are self-scheduled is nearly identical to the appropriateness of traditionally scheduled visits. CLINICAL RELEVANCE Implementation of self-scheduling systems may allow for greater patient autonomy and access to care and reduce administrative burden on office staff.

[PMID: 36809434 PMCID: PMC10121535 DOI: 10.1007/s00330-023-09446-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 12/30/2022] [Accepted: 01/18/2023] [Indexed: 02/23/2023]
Abstract
OBJECTIVES To evaluate extensor carpi ulnaris (ECU) tendon pathology and ulnar styloid process bone marrow edema (BME) as diagnostic MRI markers for peripheral triangular fibrocartilage complex (TFCC) tears. METHODS One hundred thirty-three patients (age range 21-75, 68 females) with wrist 1.5-T MRI and arthroscopy were included in this retrospective case-control study. The presence of TFCC tears (no tear, central perforation, or peripheral tear), ECU pathology (tenosynovitis, tendinosis, tear or subluxation), and BME at the ulnar styloid process were determined on MRI and correlated with arthroscopy. Cross-tabulation with chi-square tests, binary logistic regression with odds ratios (OR), and sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were used to describe diagnostic efficacy. RESULTS On arthroscopy, 46 cases with no TFCC tear, 34 cases with central perforations, and 53 cases with peripheral TFCC tears were identified. ECU pathology was seen in 19.6% (9/46) of patients with no TFCC tears, in 11.8% (4/34) with central perforations and in 84.9% (45/53) with peripheral TFCC tears (p < 0.001); the respective numbers for BME were 21.7% (10/46), 23.5% (8/34), and 88.7% (47/53) (p < 0.001). Binary regression analysis showed additional value from ECU pathology and BME in predicting peripheral TFCC tears. The combined approach with direct MRI evaluation and both ECU pathology and BME yielded a 100% positive predictive value for peripheral TFCC tear as compared to 89% with direct evaluation alone. CONCLUSIONS ECU pathology and ulnar styloid BME are highly associated with peripheral TFCC tears and can be used as secondary signs to diagnose tears. KEY POINTS • ECU pathology and ulnar styloid BME are highly associated with peripheral TFCC tears and can be used as secondary signs to confirm the presence of TFCC tears. • If there is a peripheral TFCC tear on direct MRI evaluation and in addition both ECU pathology and BME on MRI, the positive predictive value is 100% that there will be a tear on arthroscopy compared to 89% with direct evaluation alone. • If there is no peripheral TFCC tear on direct evaluation and neither ECU pathology nor BME on MRI, the negative predictive value is 98% that there will be no tear on arthroscopy compared to 94% with direct evaluation alone.

Abstract
Excessive scar formation is a hallmark of localized and systemic fibrotic disorders. Despite extensive studies to define valid anti-fibrotic targets and develop effective therapeutics, progressive fibrosis remains a significant medical problem. Regardless of the injury type or location of wounded tissue, excessive production and accumulation of collagen-rich extracellular matrix is the common denominator of all fibrotic disorders. A long-standing dogma was that anti-fibrotic approaches should focus on overall intracellular processes that drive fibrotic scarring. Because of the poor outcomes of these approaches, scientific efforts now focus on regulating the extracellular components of fibrotic tissues. Crucial extracellular players include cellular receptors of matrix components, macromolecules that form the matrix architecture, auxiliary proteins that facilitate the formation of stiff scar tissue, matricellular proteins, and extracellular vesicles that modulate matrix homeostasis. This review summarizes studies targeting the extracellular aspects of fibrotic tissue synthesis, presents the rationale for these studies, and discusses the progress and limitations of current extracellular approaches to limit fibrotic healing.

Abstract
PURPOSE Proximal interphalangeal (PIP) joint sprains are common injuries that often result in prolonged swelling, stiffness, and dysfunction; however, the duration of these sequelae is unknown. The purpose of this study was to determine the duration of time that patients experience finger swelling, stiffness, and dysfunction following a PIP joint sprain. METHODS This was a prospective, longitudinal, survey-based study. To identify patients with PIP joint sprains, the electronic medical record was queried monthly using International Classification of Disease, Tenth Revision, codes for PIP joint sprain. A five-question survey was emailed monthly for 1 year or until their response indicated resolution of swelling, whichever occurred sooner. Two cohorts were established: patients with (resolution cohort) and patients without (no-resolution cohort) self-reported resolution of swelling of the involved finger within 1 year of a PIP joint sprain injury. The measured outcomes included self-reported resolution of swelling, self-reported limitations to range of motion, limitations to activities of daily living, Visual Analog Scale (VAS) pain score, and return to normalcy. RESULTS Of 93 patients, 59 (63%) had complete resolution of swelling within 1 year of a PIP joint sprain. Of the patients in the resolution cohort, 42% reported return to subjective normalcy, with 47% having self-reported limitations in range of motion and 41% having limitations in activities of daily living. At the time of resolution of swelling, the average VAS pain score was 0.8 out of 10. In contrast, only 15% of patients in the no-resolution cohort reported return to subjective normalcy, with 82% having self-reported limitations in range of motion and 65% having limitations in activities of daily living. For this cohort, the average VAS pain score at 1 year was 2.6 out of 10. CONCLUSIONS It is common for patients to experience a prolonged duration of swelling, stiffness, and dysfunction following PIP joint sprains. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
BACKGROUND Noise-induced hearing loss (NIHL) affects the ability of an individual to communicate and can negatively impact quality of life. The risk to orthopaedic surgeons of developing NIHL as a result of occupational exposures in the operating room (OR) is currently unknown. Hearing protection is recommended for levels of >85 decibels (dB), irrespective of length of exposure. The primary goal of the present study was to determine whether orthopaedic surgeons are exposed to harmful noise levels in the OR that puts them at risk for developing NIHL. METHODS A prospective review was conducted with use of intraoperative audio recordings across 6 orthopaedic subspecialties. Recordings were made in ORs prior to the surgical start time to serve as baseline controls. Decibel levels were reported as the maximum dB level (MDL), defined as the highest sound pressure level during the measurement period, and as the time-weighted average (TWA), defined as the average dB level projected over an 8-hour time period. Noise doses were reported as the percentage of maximum allowable daily noise (dose) and as the measured dose projected forward over 8 hours (projected dose). RESULTS Three hundred audio recordings were made and analyzed. The average MDL ranged from 96.9 to 102.0 dB, with noise levels for all subspeciality procedures being significantly greater compared with the control recordings (p < 0.001). Overall, MDLs were >85 dB in 84% of cases and >100 dB in 35.0% of cases. The procedure with the highest noise dose was a microdiscectomy, which reached 11.3% of the maximum allowable daily noise and a projected dose of 104.1%. Among subspecialties, adult reconstruction had the highest dose and projected dose per case among subspecialties. CONCLUSIONS The present results showed that orthopaedic surgeons are regularly exposed to damaging noise levels (i.e., >85 dB), putting them at risk for permanent hearing loss. Further investigation into measures to mitigate noise exposure in the OR and prevent hearing loss in orthopaedic surgeons should be undertaken. CLINICAL RELEVANCE Orthopaedic surgeons are at risk for NIHL as a result of occupational exposures in the OR.

Abstract
Intramedullary screw fixation provides a less-invasive means of surgically managing metacarpal fractures. While there are advantages to using this technique compared to CRPP and ORIF, disadvantages of intramedullary screw fixation include loss of reduction intraoperatively due to sagittal and coronal plane translation. The blocking screw technique has been previously described as a solution for this problem in intramedullary fixation of long bone fractures. We describe the blocking screw technique as applied to aid intramedullary screw fixation of metacarpals.

Abstract
BACKGROUND Orthopedic procedures concerning the upper extremity commonly use a brachial plexus nerve block to achieve postoperative analgesia. The addition of dexamethasone to peripheral nerve blocks has been shown to significantly prolong its effect. We hypothesize that 1 mg doses of dexamethasone will prolong brachial plexus nerve block with similar efficacy to 4 mg and better than ropivacaine alone. METHODS Seventy-nine patients who received a brachial plexus nerve block prior to undergoing upper extremity surgery were randomized to 1 of 4 treatment groups: group 1 received only 30 mL of 0.5% ropivacaine without dexamethasone (control); groups 2, 3, and 4 received 4, 2, and 1 mg of dexamethasone, respectively, added to 30 mL of 0.5% ropivacaine. RESULTS Comparison of block duration, specifically "first signs of the block wearing off" to the 0-mg group, referencing the 1-, 2-, and 4-mg groups (P = .02, .04, and .01, respectively) that received steroid adjuvant therapy demonstrated a significant increase in time until the block began to wear off. All study groups receiving steroids also demonstrated a significant increase in duration of the block prior to its effects being completely gone when compared with the control group (P < .01 for all groups). CONCLUSIONS Our findings demonstrate that adjuvant dexamethasone can prolong brachial plexus nerve blocks effectively at low doses compared with high doses, in addition to prolonging analgesia compared with local anesthetic alone.

Abstract
BACKGROUND Adequate pain control is critical after outpatient surgery where patients are not as closely monitored. A multimodal pain management regimen was compared to a conventional pain management method in patients undergoing operative fixation for distal radius fractures. We hypothesized that there would be a decrease in the amount of narcotics used by the multimodal group compared to the conventional pain management group, and that there would be no difference in bone healing postoperatively. METHODS Forty-two patients were randomized into 2 groups based on pain protocols. Group 1, the control, received a regional block, acetaminophen, and oxycodone. Group 2 received a multimodal pain regimen consisting of daily doses of pregabalin, celecoxib, and acetaminophen up until postoperative day (POD) #3. They also received a regional block with oxycodone for breakthrough pain. RESULTS From POD#3 to week 1, there was a significant increase in oxycodone use in the study group correlating with the point in time when the multimodal regimen was discontinued. The shortened Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH) scores taken at 2 weeks postoperation showed a significantly lower average score in the study group compared to the control. There was no difference in bone healing. CONCLUSIONS The 2 regimens yielded similar pain control after surgery. The rebound increase in narcotic use after the multimodal regimen was discontinued, and significant difference in QuickDASH scores seen at 2 weeks postoperatively supported that multimodal regimens may not necessarily lead to decreased narcotic use in outpatient upper extremity surgery, but in the short term are shown to improve functional status.

Abstract
BACKGROUND On January 1, 2021, the American Medical Association implemented changes regarding the outpatient Evaluation and Management (E/M) criteria dictating Current Procedural Terminology code level selection to help diminish administrative burden and emphasize medical decision-making as the primary determinant in E/M level of service (EML). The goal of this study was to describe EML coding trends in outpatient visits for hip and knee osteoarthritis after the 2021 Centers for Medicare and Medicaid Services changes to the E/M system. METHODS All outpatient visits for primary hip and knee osteoarthritis within the divisions of Joint Replacement, Operative Sports Medicine, and Nonoperative Sports Medicine at a single orthopaedic practice were retrospectively analyzed during 2 separate 10-month timeframes in 2019 and 2021. The primary endpoint was the visit EML (1 through 5) based on Current Procedural Terminology E/M codes. RESULTS In 2019, 7.8% of all visits were billed as level 2, 85.8% of all visits were billed as level 3, and 6.3% of all visits were billed as level 4. In 2021, 2.8% of visits were billed as level 2, 54% of visits were billed as level 3, and 41.3% of visits were billed as level 4. Level 1 and Level 5 visits did not exceed 2% in either year. Across all 3 divisions, level 2 and 3 visits decreased significantly (P < .05), while level 4 visits increased significantly (P < .05). CONCLUSION Since the E/M coding criteria overhaul in 2021, there has been a significant trend towards higher level of service code selection across multiple divisions in our orthopaedic practice.

Abstract
BACKGROUND Mallet finger is a common injury involving a detachment of the terminal extensor tendon from the distal phalanx. This injury is usually treated with immobilization in a cast or splint. The purpose of this study is to compare outcomes of mallet fingers treated with either a cast (Quickcast) or a traditional thermoplastic custom-fabricated orthosis. METHODS Our study was a prospective, assessor-blinded, single-center randomized clinical trial of 58 consecutive patients with the diagnosis of bony or soft tissue mallet finger treated with immobilization. Patients were randomized to either an orfilight thermoplastic custom-fabricated orthosis or a Quickcast orthosis. Patients were evaluated at 3, 6, and 10 weeks for bony and 4, 8, and 12 weeks for soft tissue mallets. Skin complications, pain with orthosis, compliance, need for surgical intervention, and extensor lag were compared between the 2 groups. RESULTS Both bony and soft tissue mallet finger patients experienced significantly less skin complications (33% vs 64%) and pain (11.2 vs 21.6) when using Quickcast versus an orfilight thermoplastic custom-fabricated orthosis. The soft tissue mallet group revealed a greater difference in pain, favoring Quickcast (6.2 vs 22). No significant difference in final extensor droop or need for secondary surgery was found between the 2 groups. CONCLUSIONS Quickcast immobilization for the treatment of mallet finger demonstrated fewer skin complications and less pain compared with orfilight custom-fabricated splints.

Abstract
BACKGROUND Medicare (MCR) and Medicaid (MCD) remain the dominant providers of government-funded health insurance in the United States. The purpose of this study was to evaluate the variability between MCR and MCD reimbursements for common hand and wrist surgical procedures. We hypothesized that MCD reimbursement rates would have substantial variation between states, whereas MCR rates would remain relatively constant. METHODS Using the Medicare Physician Fee Schedule Database, the 2019 reimbursements for 7 common hand and wrist procedures were recorded via the respective Current Procedural Terminology codes. The MCD reimbursement rates were then obtained from each state's physician fee schedule database. Comparisons of reimbursement for these procedures were then calculated between states and between MCD and MCR while adjusting for cost of living using the Medicare Wage Index. Finally, the coefficients of variation were computed to compare the extent of variability between the insurance types. RESULTS Across all procedures, reimbursement rates for MCD ranged from 30.6% to 240% of the average MCR reimbursement, with the mean reimbursement for MCD valued at 78.3% of MCR. Endoscopic carpal tunnel release (CTR) is valued similarly by MCD compared with open CTR with an average of 77.7% and 78.2% reimbursement of MCR, respectively. The coefficients of variation for MCD reimbursements ranged from 0.25 to 0.45, whereas the value was 0.06 for all MCR procedures. CONCLUSIONS These findings demonstrate a wide variation in MCD payments between states. When compared with MCR, the lower average state MCD reimbursement questions the sustainability for hand surgeons to accept these patients in practice.
