Interspecialty Variation in Perioperative Health Care Resource Usage for Carpal Tunnel Release.

BACKGROUND: We investigated whether any interspecialty variation exists, regarding perioperative health care resource usage, in carpal tunnel releases (CTRs). METHODS: The 2010 to 2021 PearlDiver Mariner Database, an all-payer claims database, was queried to identify patients undergoing primary CTRs. Physician specialty IDs were used to identify the specialty of the surgeon-orthopedic versus plastic versus general surgery versus neurosurgery. Multivariate logistic regression analysis was used to identify whether there was any interspecialty variation between the use of health care resources. RESULTS: A total of 908 671 patients undergoing CTRs were included, of which 556 339 (61.2%) were by orthopedic surgeons, 297 047 (32.7%) by plastic surgeons, 44 118 (4.9%) by neurosurgeons, and 11 257 (1.2%) by general surgeons. In comparison with orthopedic surgeons, patients treated by plastic surgeons were less likely to have received opioids, nonsteroidal anti-inflammatory drugs, oral steroids, and preoperative antibiotic prophylaxis but were more likely to have received steroid injections and electrodiagnostic studies (EDSs) preoperatively. Patients treated by neurosurgeons were more likely to have received preoperative opioids, gabapentin, oral steroids, preoperative antibiotic prophylaxis, EDSs, and formal preoperative physical/occupational therapy and less likely to have received steroid injections. Patients treated by general surgeons were less likely to receive oral steroids, steroid injections, EDSs, preoperative formal physical therapy, and preoperative antibiotic prophylaxis, but were more likely to be prescribed gabapentin. CONCLUSIONS: There exists significant variation in perioperative health care resource usage for CTRs between specialties. Understanding reasons behind such variation would be paramount in minimizing differences in how care is practiced for elective hand procedures.

Complications in Hand Surgery During Early Independent Practice: A Single Surgeon's 5-Year Experience.

BACKGROUND: The objective of this study was to understand the frequency and types of complications, and the associated postoperative outcomes within the first 5 years of practice after hand and upper extremity surgery fellowship. METHODS: This was a retrospective observational study of all patients seen and surgically treated by a single surgeon at a single institution from August 2014 to September 2019. This corresponded to the first 5 years of practice after fellowship. Data collected included patient demographics, perioperative data, complication type, and outcome of the complication (better/same/worse than preoperative status). Complications were classified using the Clavien-Dindo system and a unique, self-derived system. RESULTS: In total, 3301 surgeries were performed during the first 5 years of practice. The overall complication rate was 7.9% (261 complications from 239 patients). The 30-day complication rate was 5.2% (171/3301). Eleven (4.2%) of the 261 complications occurred intraoperatively. The total number of complications significantly declined during the first 5 years of practice as follows: 74, 71, 46, 37, and 33 (P = .010, R2 = .92). Hand and wrist were the most frequent anatomic locations involved and bone pathology was the predominant indication. CONCLUSION: The overall surgical complication rate for hand and upper extremity surgery was 7.9%, with a 30-day complication rate of 5.2% (171/3301). The rate of complications after fellowship declined over the first 5 years of independent practice. Superficial infections were the most common complication. More than 90% of patients ultimately improved after addressing the complication. LEVEL OF EVIDENCE: IV.

Risk Factors for Secondary Revision After Finger Amputations.

BACKGROUND: Digit amputations are relatively simple and are often performed in the setting of trauma or infection. However, it is not uncommon for digit amputations to undergo secondary revision due to complications or patient dissatisfaction. Identifying factors associated with secondary revision may alter treatment strategy. We hypothesize that the secondary revision rate is affected by digit, initial level of amputation, and comorbidities. METHODS: A retrospective chart review was conducted on patients undergoing digit amputations in operating rooms at our institution from 2011 to 2017. Secondary revision amputations were defined as a separate return to the operating room following initial surgical amputation, excluding emergency room amputations. Patient demographics, comorbidities, level of amputation, and complications were collected. RESULTS: In all, 278 patients were included with a total of 386 digit amputations and mean follow-up of 2.6 months. Three hundred twenty-six primary digit amputations were performed in 236 patients (group A). Sixty digits were secondarily revised in 42 patients (group B). The secondary revision rate was 17.8% for patients and 15.5% for digits. Patients with heart disease and diabetes mellitus were associated with secondary revision, with wound complications being the leading indication overall (73.8%). Medicare covered 52.4% of patients in group B versus 30.1% in group A (P = .005). CONCLUSION: Risk factors for secondary revision include Medicare insurance, comorbidities, previous digit amputations, and initial amputation of either the index finger or the distal phalanx. These data may serve as a prediction model to aid surgical decision-making by identifying patients at risk of secondary revision amputation.

Declining Trend in Anti-osteoporotic Treatment, Despite a Rise in DEXA Screening Following "Sentinel" Distal Radius Fractures.

PURPOSE: To understand national trends and costs associated with the utilization of anti-osteoporotic medication and DEXA screening within the year following a sentinel/primary distal radius fracture. METHODS: The 2008-2015Q1 Humana Administrative Claims database was queried to identify patients aged ≥50 years, with a "sentinel" occurrence of a primary closed distal radius fracture. Linear regression models were used to report and assess for significant trends in utilization of anti-osteoporotic medication and DEXA screenings within the year following the fracture. Multivariate logistic regression analyses were used to assess for factors associated with receiving or not receiving anti-osteoporotic medication. RESULTS: A total of 14 526 sentinel distal radius fractures were included in the study. Only 7.2% (n = 1046) of patients received anti-osteoporosis medication in the year following the distal radius fracture. Treatment with medication for osteoporosis declined from 8.2% in 2008 to 5.9% in 2015, whereas the rate of DEXA screening increased from 14.8% in 2008 to 23.6% in 2015. The most common prescribed treatment was alendronate sodium (n = 835; 79.8%-$49/patient). Factors associated with increased odds of receiving anti-osteoporotic medication were age 70 to 79 years (odds ratio [OR], 1.45; P = .014), age 80 to 89 years (OR, 1.66; P = .001), Asian (OR, 2.95; P = .002) or Hispanic (OR, 1.77; P = .006) ethnicity, belonging to South (OR, 1.19; P = .029) or West (OR, 1.37; P = .010), and having an Elixhauser Comorbidity Index score of 3 (OR, 2.14; P = .024) or > 3 (OR, 2.05; P = .022). CONCLUSIONS: Despite a rising utilization of DEXA screening following "sentinel" distal radius fractures, the proportion of individuals who receive anti-osteoporotic treatment is decreasing over time.

Fracture Gap Closure and Reduction Are Affected by the Orientation of the Headless Compression Screw.

BACKGROUND: We evaluated the impact of a variable-pitch headless screw's angle of insertion relative to the fracture plane on fracture gap closure and reduction. METHODS: Variable-pitch, fully threaded headless screws were inserted into polyurethane blocks of "normal" bone model density using a custom jig. Separate trials were completed with a 28-mm screw placed perpendicular and oblique/longitudinal to varying fracture planes (0°, 15°, 30°, 45°, and 60°). Fluoroscopic images were taken after each turn during screw insertion and analyzed. Initial screw push-off, residual fracture gap at optimal fracture gap reduction, and malreduction were determined in each trial. Statistical analysis was performed via a 1-way analysis of variance followed by Student t tests. RESULTS: Malreduction was found to be significantly different between the perpendicular (1.88 mm ± 1.38) and the oblique/longitudinal (0.58 mm ± 0.23) screws. The malreduction increased for the perpendicular screw as the fracture angle increased (60° > 45°=30° > 15° > 0°). Residual fracture gap at optimal fracture gap reduction was also found to be significantly different between the perpendicular (0.97 ± 0.42) and oblique/longitudinal (1.43 ± 1.14) screws. The residual fracture gap increased for the oblique/longitudinal screw as the fracture angle increased, although the oblique/longitudinal screw with a 60° fracture angle was the only configuration significantly larger than all the other configurations. Screw push-off was not found to be significantly different between the oblique/longitudinal screw and perpendicular screw trials. CONCLUSIONS: The perpendicular screw had a larger malreduction that increased with fracture angle, whereas the oblique/longitudinal screw had a larger residual fracture gap that increased with fracture angle.

Firework Injuries to the Hand in the United States: An Epidemiological and Cost Analysis.

Although prior literature has evaluated firework injuries broadly, there are no focused investigations examining trends, etiology, and costs associated with firework injuries to the hand. The 2006 to 2014 National Emergency Department Sample (NEDS) was used. International Classification of Diseases, Ninth Revision (ICD-9) codes identified patients presenting to the emergency department with a firework-related injury of the hand that resulted in a burn, open wound, fracture, blood vessel injury, or traumatic amputation. A linear regression model was used to identify significant changes over time, with a significance threshold of P<.05. A total of 19,473 patients with a firework-related injury to the hand were included, with no significant change in the incidence from 2006 to 2014 (7.5 per 1,000,000 population). The greatest number of injuries occurred in July (57.1%), January (7.4%), and December (3.7%). Age groups affected were young adults (18-35 years; 43.6%), older adults (36-55 years; 19.2%), adolescents (12-17 years; 18.6%), and children (0-11 years; 16.1%). Nearly 74% of the injuries resulted in burns, 24.5% resulted in open wounds, 8.0% resulted in fracture, 7.6% resulted in traumatic amputation, and 1.4% resulted in blood vessel injury. Of 14,320 burn injuries, 15.2% had first-degree burns, 69.9% had second-degree burns, and 5.1% had third-degree burns involving the skin. The median emergency department charge was $914 and the median hospitalization charge (for inpatient admittance) was $30,743. Incidence of firework-related injuries to the hand has not changed over time. There is a need for better dissemination of safety information to mitigate the occurrences of these avoidable accidents.

The Effect of Derotational Kirschner Wires on Fracture Gap Reduction With Variable-Pitch Headless Screws.

PURPOSE: We evaluated the impact of angled derotational Kirschner wires (K-wires) on fracture gap reduction with variable-pitch headless screws. METHODS: Fully threaded variable-pitch headless screws (20 and 28 mm) were inserted into "normal" bone models of polyurethane blocks. In separate trials, derotational K-wires were inserted at predetermined angles of 0°, 15°, 30°, and 40° and compared with each other, with no K-wire as a control. Fluoroscopic images taken after each screw turn were analyzed. The optimal fracture gap closure, initial screw push-off, and screw back-out gap creation were determined and compared at various derotational K-wire angles. RESULTS: Initial screw push-off due to screw insertion and screw back-out gap creation were not significantly affected by the angle of the derotational K-wire. With a 20-mm screw, only a 40° derotational K-wire led to significantly less gap closure compared with control and with 0°, 15°, and 30° derotational K-wires. It led to an approximately 60% decrease in gap closure compared with no K-wire. With the 28-mm screw, compared with no K-wire, 15° and 30° derotational K-wires led to statistically significant decreases in gap closure (approximately 25%), whereas a 40° derotational K-wire led to an approximately 60% decrease. With the 28-mm screw, the 40° derotational K-wire also led to a statistically significant smaller gap closure when compared with 0°, 15°, and 30° derotational K-wires. CONCLUSIONS: A derotational K-wire placed in parallel to the planned trajectory of a headless compression screw does not affect fracture gap closure. With greater angulation of the derotational K-wire, the fracture gap is still closed, but less tightly. CLINICAL RELEVANCE: Derotational K-wires can help prevent fracture fragment rotation during headless compression screw insertion. At small deviations from parallel (≤30°), fracture gap closure achieved by the screw is minimally affected. At greater angles (ie, 40°), fracture gap closure may be substantially reduced, preventing fracture compression.

Risk Factors for Loss of Reduction After Open Reduction and Internal Fixation of Isolated Olecranon Fractures in Adults.

BACKGROUND: We sought to determine whether any relevant patient, fracture, surgical, or postoperative characteristics are associated with loss of reduction after plate fixation of isolated olecranon fractures in adults. METHODS: Patients who underwent open reduction and internal fixation of an olecranon fracture at our institution over an 11-year period were analyzed. Electronic patient charts and radiographic images were reviewed to gather patient, fracture, surgical, and postoperative data. Statistical analysis to explore the differences between groups was performed. RESULTS: Seven of 96 patients experienced a loss of fracture reduction diagnosed at a median of 19 days after their initial surgery (range: 4-116 days). The radiographic mode of failure of all patients who lost reduction was proximal migration of the proximal fracture fragment with or without implant failure. The group that lost reduction had a significantly smaller proximal fragment (14.2 vs 18.6 mm), a higher incidence of malreduction with a persistent articular step-off greater than 2 mm (6/7 vs 14/89), a greater distance between the most proximal screw and the olecranon tip (19.8 vs 13.5 mm), a higher proportion of constructs with screws placed outside of the primary plate (4/7 vs 14/89), and a higher proportion of patients that were not immobilized postoperatively (3/7 vs 8/89). CONCLUSIONS: Our results suggest anatomical reduction at the articular surface and adequate fixation of the proximal fragment are key factors in maintenance of reduction, with smaller proximal fragments being at higher risk for failure. A period of postoperative immobilization may decrease the risk of loss of reduction.

Role of Dynamic Stabilizers of the Elbow in Radiocapitellar Joint Alignment: A Prospective In Vivo Study.

PURPOSE: To investigate the effect of dynamic stabilizers of the elbow on radiocapitellar joint alignment, before and after the administration of regional anesthesia. METHODS: At a single institution, 14 patients were prospectively enrolled in a study using a within-subjects control design. Before performing a supraclavicular regional block, 10 fluoroscopic images (1 anteroposterior and 9 lateral views) of the elbow were obtained for each patient. The lateral images were obtained with the forearm in maximal supination, neutral rotation, and maximal pronation, and these forearm positions were repeated for 3 elbow positions: (1) full extension; (2) flexion to 90°, with 0° of shoulder internal rotation; and (3) flexion to 90°, with 90° of shoulder internal rotation. After obtaining the 10 initial images, a block was performed to achieve less than 3/5 motor strength of the imaged extremity, followed by obtaining the same 10 images in each patient. Radiocapitellar ratio, defined as the minimal distance between the right bisector of the radial head and the center of the capitellum divided by the diameter of the capitellum, was measured in each image. RESULTS: The 14 patients had a mean age of 47.8 ± 15.7 years, and 10 (71.4%) patients were women. A difference between radiocapitellar ratios measured before and after the regional block administration was observed for all lateral images (-1.0% ± 7.2% to -2.2% ± 8.0%), although this difference was less than the minimum clinically important difference. CONCLUSIONS: Paralysis of the dynamic stabilizers of the elbow produces a difference in the radiocapitellar joint alignment, but this did not reach the minimum clinically important difference. CLINICAL RELEVANCE: Paralysis of the dynamic stabilizers of the elbow via a supraclavicular nerve block produces no clinically relevant effect on the radiocapitellar alignment of uninjured elbows.

Total Wrist Fusion with an Intramedullary Device: A Single-Institution Series with a Minimum of One Year Follow-Up.

Objective The primary purpose of this study was to evaluate the functional and surgical outcomes of total wrist fusion (TWF) following the use of a locked intramedullary nail (IMN). Methods A single institution study was performed, which entailed in-person reexamination of 18 patients ( n = 19 wrists), out of 35 eligible patients, who underwent TWF with an IMN from 2010 to 2017. For each patient, demographic, preoperative diagnosis, physical examination, wrist radiograph, and outcome questionnaire data were obtained. The questionnaires included the visual analog scale (VAS), quick disabilities of the arm, shoulder, and hand (QuickDASH), and Mayo Wrist Score assessments. In addition, complication and reoperation data for all TWFs with an IMN during the 2010 to 2017 period (35 patients, n I = 38 wrists) were noted. Results In the 18 patients, age was 47.6 ± 13.9 years, 12 (63.2%) were female, and median follow-up was 150 weeks (range: 74-294). The VAS score was 0 ± 0 in 5 of 19 wrists with rheumatoid arthritis (RA) and 1.82 ± 2.78 in 14 of 19 wrists without RA. It was found that 21 of 38 wrists (55.3%) had an implant-related complication and 5 wrists (13%) underwent a reoperation due to the implant itself. Conclusions To date, no sufficient data are present demonstrating a clear advantage of an IMN over dorsal plating for TWF at intermediate-term follow-up. Surgeons should be knowledgeable of the several potential complications of this IMN prior to its use for TWF. Level of Evidence This is a Level IV, therapeutic study.

Written Prescription for Over-the-Counter Nonopioid Pain Medications Does Not Increase the Likelihood of Use after Ambulatory Hand and Upper Extremity Surgery.

Introduction This study looked to determine how providing written prescriptions of nonopioids affected postoperative pain medication usage and pain control. Materials and Methods Patients undergoing hand and upper-extremity surgery ( n = 244) were recruited after the implementation of a postoperative pain control program encouraging nonopioids before opioids. Patients were grouped based on procedure type: bone ( n = 66) or soft tissue ( n = 178). Patients reported postoperative medication consumption and pain control scores. Two-tailed t -tests assuming unequal variance were performed to look for differences in postoperative pain control and medication consumption between those who were and were not given written prescriptions for nonopioids. Results For both soft tissue and bone procedure patients, a written prescription did not significantly affect patients' postoperative pain control or medication consumption. Regardless of receiving a written prescription, patients who underwent soft tissue procedures consumed significantly more daily nonopioids than opioids. Conclusion Receiving written prescriptions for nonopioids may not have a significant effect on postoperative pain control or medication consumption. Patients undergoing soft tissue hand and upper extremity procedures may be more likely to consume more daily nonopioids than opioids postoperatively compared to bone procedure patients regardless of whether they receive a written prescription for nonopioids.

Treatment Patterns for Distal Radius Fractures Before and After Appropriate Use Criteria Adoption.

BACKGROUND: The purpose of this study was to determine agreement with the American Academy of Orthopaedic Surgery Appropriate Use Criteria (AUC) for distal radius fractures (DRFs), before and after their adoption, and secondarily determine predictors of operative management. METHODS: A single-institution retrospective cohort study comparing patients treated either nonoperatively (115 patients) or operatively (767 patients) for DRFs between May 1, 2008, and May 1, 2018, by 8 hand surgeons was performed. Data included demographics, injury characteristics, DRF radiographic measurements, treatment rendered, and their appropriateness according to the AUC. Statistical testing used the Fisher and χ2 tests, t test, and multiple variable logistic regression, with a significance level of .05. RESULTS: Overall, there was a significant increase in AUC agreement for operatively treated DRFs (82.7%-89.3%, P = .01), but no difference in agreement for nonoperatively treated DRFs (12.5%-10.7%, P = .77). Age <80 years, AO classes other than B, intra-articular displacement >1 mm, radial inclination <18°, high-energy mechanism of injury, and greater than 1 week to treatment were independent predictors of operative treatment. The area under the curve for the validated regression model using the aforementioned predictors was 0.82. CONCLUSION: Agreement with AUC for DRFs increased after its adoption for operatively treated, but not for nonoperatively treated, fractures. In addition, a predictive model for operative treatment was developed and validated. Future studies may benefit from further model refinement and testing in other patient cohorts.

The effect of patient factors on opioid use after anatomic and reverse shoulder arthroplasty.

BACKGROUND: Prolonged opioid use can lead to suboptimal outcomes after total shoulder arthroplasty (TSA), and thus, reduced consumption is desirable. Our primary aims were to determine if differences in total morphine equivalent doses existed owing to (1) age less than or greater than 65 years, (2) sex, and (3) TSA type - reverse or anatomic total shoulder arthroplasty. We also characterized potential risk factors for (1) visiting another provider for pain, (2) pain control 6 weeks postoperatively, and (3) needing an opioid refill. METHODS: A retrospective cohort study of 100 patients who underwent TSA (reverse total shoulder arthroplasty N 1 = 50; anatomic total shoulder arthroplasty N 2 = 50) between 1 July 2018 and 31 December 2018 was performed. Demographics, perioperative treatments, and postoperative opioid prescriptions were recorded. Primary hypotheses were evaluated with Wilcoxon-Mann-Whitney testing. Univariate and multivariate analyses assessed potential risk factors for the 3 outcomes of interest. Results were given in adjusted odds ratios (aORs), 95% confidence intervals (CIs), and P values. RESULTS: There was a difference (P = .009) in total morphine equivalent doses used (in 5-milligram oxycodone tablets) between patients who were younger than 65 years of age (median: 83 tablets, interquartile range: 62-140) and those who were older than 65 years of age (median: 65 tablets, interquartile range: 52-90). Unemployment (aOR = 4.68, CI: 1.5-14.2, P = .006) and age less than 65 years (aOR = 4.18, CI: 1.6-11.2, P = .004) were independent risk factors for inadequate pain control 6 weeks postoperatively. Two independent risk factors for needing an opiate prescription refill after discharge were unemployment (aOR = 4.56, CI: 1.5-13.8, P = .007) and preoperative opiate use (aOR = 3.95, CI: 1.4-11.0, P = .009). CONCLUSION: After TSA, morphine equivalent dose usage is higher for patients younger than 65 years of age, and several risk factors exist for requiring a refill and having inadequate pain control 6 weeks postoperatively. Prospective studies using these data to guide interventions may be beneficial.

Trends of hand injuries presenting to US emergency departments: A 10-year national analysis.

BACKGROUND: The purpose was to observe current incidence and trends of hand and wrist injuries presenting to U.S. emergency departments (EDs) over a decade. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for hand and wrist injuries from January 2009-December 2018. Descriptive analyses were used to report injury types to the hand and wrist. Incidence, age, gender, race, injury location, and type of injury were recorded. Linear regression analyses were used to assess changes in trends over time. A p value <0.05 was statistically significant. RESULTS: In total, 649,131 cases of hand and wrist injuries were identified in the NEISS from 2009 to 2018, correlating to 25,666,596 patients nationally. Incidence rates for finger, hand, and wrist were 450, 264, and 182 per 100,000 people. The estimated number of patients per year declined by 8.6% from 2009 to 2018. Male adults (aged 18-39) were the most frequent demographic. Total national estimates of hand (-8.2%; p = 0.001), wrist (-6.1%; p = 0.007), and finger (-9.9%; p < 0.001) injuries declined over the study period. The most common injuries were lacerations (36.5%), fractures (19.9%), strains/sprains (12.3%), and contusions/abrasions (12.1%) which significantly declined over the study period. The overall admission rate was 1.8%. CONCLUSIONS: The estimated annual number of hand/wrist injuries presenting to US EDs was 2.6 million with gradual decline over the decade. Hand injury registries could assist in quality improvement measures targeted toward increased efficiency and resource allocation and education.

Cost Analysis of Medical Students Applying to Orthopaedic Surgery Residency: Implications for the 2020 to 2021 Application Cycle During COVID-19.

Although studies have evaluated the economic burden to medical students desiring an orthopaedic residency broadly, no study has evaluated in detail the application costs, away rotation costs, interview costs, and total costs. Given that the Association of American Medical Colleges and the American Orthopaedic Association's Council of Orthopaedic Residency Directors have recommended orthopaedic surgery residency programs for the 2021 residency application cycle cancel away rotations and in-person interviews, our objective was to evaluate the cost savings to medical students applying during this time and the potential implications. METHODS: Using the 2019 to 2020 Texas STAR Dashboard database, we queried responses from applicants applying to orthopaedic surgery residency. The dashboard was queried to record the application costs, away rotation costs, interview costs, and total costs for medical school seniors applying to orthopaedic surgery residency. Demographic information for applicants was also recorded. Mean and median costs were reported with percentile distributions and geographic comparisons. A Kruskal-Wallis H test was used to determine whether there were statistically significant differences in mean costs by medical school region. RESULTS: The 2019 to 2020 Texas STAR Dashboard database had 473 responses from applicants to orthopaedic surgery residency. The mean application costs were $1,990, away rotation costs were $3,182, interview costs were $3,129, and total costs were $8,205. The mean total costs for applicants from Midwest schools were significantly less than Western schools ($7,410/applicant vs. $9,909/applicant) (p = 0.008). There was no significant difference between the mean application fees between regions. Away rotation costs for applicants from schools in the Midwest ($2,413/applicant) were significantly less compared with Northeast ($3,279/applicant), South ($3,343/applicant), and West ($3,913/applicant) (all p < 0.002). Interview costs for applicants from schools in the Northeast ($2,891/applicant) were less than applicants from Western US schools ($3,831/applicant) (p = 0.038). CONCLUSION: In the COVID-19 era, orthopaedic residency applicants could save on average $6,311 through the use of virtual interviews and lack of away rotations. There are geographic implications, with applicants from Western US medical schools potentially saving most.

Outcomes following Distal Radius Fractures with Preexisting Ulnocarpal Abutment.

Background Due to the commonality of distal radius fractures (DRFs), the potential impact of ulnocarpal abutment (UA) on patient outcomes is significant, whether it developed after or prior to injury. It is, therefore, important to consider whether preexisting UA has any impact on outcomes after an acute DRF. Questions/Purpose The aims of this study were to determine if differences were present in (1) pain at final follow-up, (2) complications, and (3) unintended operations in patients with DRFs and either without or with preexisting radiographic UA. Methods A single institution retrospective cohort study comparing patients treated either nonoperatively (43 patients) or operatively (473 patients) for DRFs between 5/1/2008 to 5/1/2018 was performed. Data included demographics, prior wrist pain or surgery, ulnar variance, select treatment data, and presence of pain, complication, or unintended operation by final follow-up. Statistical testing used Fisher's exact test and chi-squared test, with a significance level of 0.05. Results The prevalence of preexisting UA was 14.0 and 15.6% in the nonoperatively- and operatively treated groups, respectively. In nonoperatively treated patients without or with UA, no differences in pain (37.8 vs. 33.3%, p = 1.00) or complications were seen (13.5 vs. 50.0%, p = 0.07). A higher unintended operation rate for nonoperatively treated DRFs with UA, compared with those without, UA was seen (5.4 vs. 50.0%, p = 0.01). No differences in pain, complications, or unintended operations were seen between those without and with UA in the operatively treated group. Conclusion Preexisting UA is not associated with pain, complications, or unintended operations after operative treatment of DRFs. Prospective studies further evaluating outcomes in nonoperatively treated DRFs with UA may be beneficial.

The Effect of Patient and Surgical Factors on Opioid Prescription Requests Following Arthroscopic Rotator Cuff Repair.

PURPOSE: To determine whether differences in total morphine equivalent doses (MEDs) prescribed after arthroscopic rotator cuff repair (RCR) existed because of age younger than or older than 55 years and sex and to characterize potential risk factors for needing an opioid medication refill, visiting a provider other than the surgeon (either in the emergency department or ambulatory settings), and postoperative pain control requiring opioids approximately 6 weeks from the date of surgery. METHODS: A retrospective cohort study of 100 patients who underwent arthroscopic RCR between July 1, 2018, to November 30, 2018, in a single institution was performed. Data including demographics, perioperative treatments, and postoperative opioid prescriptions were recorded. Our primary hypotheses were evaluated with the Wilcoxon-Mann-Whitney test. Univariate and multivariate analyses assessed potential risk factors for the 3 outcomes of interest. Results were given in adjusted odds ratios (aORs), 95% confidence intervals (CIs), and P values. RESULTS: There was a difference (P = .038) in total MEDs used (in 5 mg oxycodone tablets) between males (median 56 tablets; interquartile range, 50-98 tablets) and females (median 78 tablets; interquartile range, 56-116 tablets). Age younger than 55 years was a risk factor for seeking an opioid refill (OR = 2.51; CI, 1.11-5.66; P = .026). A significant risk factor for visiting another provider was preoperative opiate use (OR = 15.0; CI, 1.79-125.8; P = .013). Age younger than than 55 years (aOR = 2.51; CI, 1.01-6.02; P = .047), body mass index (aOR = 1.08; CI, 1.01-1.17; P = .046), and shorter surgical duration (aOR = 0.97; CI, 0.95-0.99, P =.007) were independent predictive factors for requiring opioids for pain control 6 weeks after surgery. CONCLUSIONS: After arthroscopic RCR, MED prescription is higher for females than males. The risk factors for requesting opioid prescription refill for pain control 6 weeks after surgery were age younger than 55 years and shorter surgical duration. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

An Update on Loss to Follow-up After Upper Extremity Surgery: Survey of Patient Responses.

Background: Incomplete patient follow-up is a common problem after hand and upper extremity (HUE) surgery and is influenced by many demographic factors. The aims of this investigation are to determine patient-stated factors for lack of follow-up, identify potential interventions, and measure satisfaction following operations. Methods: A prospective survey sampling of 173 of 655 patients lost to follow-up after HUE operations in a single institution between June 2014 and July 2015 was performed. Demographic variables collected included age, sex, distance to clinic, insurance payor, and length of time to last follow-up visit. Survey responses regarding reasons for insufficient follow-up, future recommendations, and overall satisfaction were recorded. Statistical results were reported as P values, odds ratios (ORs), and 95% confidence intervals (CIs). Results: More than half (65.3%) of 173 patients erroneously thought that they had completed follow-up, with private insurance being the only risk factor (OR = 2.45, P = .010, 95% CI = 1.24-4.85). Other common reasons for insufficient follow-up included not placing the appointment into a personal calendar (7%), excessive costs (6%), and transportation (5%). Approximately half (51%) of 55 patients aware that they had missed follow-up stated that no intervention would have helped. Median patient satisfaction with their operation was 10/10 (interquartile range = 8-10). Conclusions: Most patients lost to follow-up after HUE operations were not aware that they had a follow-up appointment, but were nevertheless satisfied with treatment. Interventions targeted to patients who erroneously thought they had followed up may be the most beneficial.

Inpatient and outpatient opioid requirements after total joint replacement are strongly influenced by patient and surgical factors.

AIMS: Currently, there is no single, comprehensive national guideline for analgesic strategies for total joint replacement. We compared inpatient and outpatient opioid requirements following total hip arthroplasty (THA) versus total knee arthroplasty (TKA) in order to determine risk factors for increased inpatient and outpatient opioid requirements following total hip or knee arthroplasty. METHODS: Outcomes after 92 primary total knee (n = 49) and hip (n = 43) arthroplasties were analyzed. Patients with repeat surgery within 90 days were excluded. Opioid use was recorded while inpatient and 90 days postoperatively. Outcomes included total opioid use, refills, use beyond 90 days, and unplanned clinical encounters for uncontrolled pain. Multivariate modelling determined the effect of surgery, regional nerve block (RNB) or neuraxial anesthesia (NA), and non-opioid medications after adjusting for demographics, ength of stay, and baseline opioid use. RESULTS: TKAs had higher daily inpatient opioid use than THAs (in 5 mg oxycodone pill equivalents: median 12.0 vs 7.0; p < 0.001), and greater 90 day use (median 224.0 vs 100.5; p < 0.001). Opioid refills were more likely in TKA (84% vs 33%; p < 0.001). Patient who underwent TKA had higher independent risk of opioid use beyond 90 days than THA (adjusted OR 7.64; 95% SE 1.23 to 47.5; p = 0.01). Inpatient opioid use 24 hours before discharge was the strongest independent predictor of 90-day opioid use (p < 0.001). Surgical procedure, demographics, and baseline opioid use have greater influence on in/outpatient opioid demand than RNB, NA, or non-opioid analgesics. CONCLUSION: Opioid use following TKA and THA is most strongly predicted by surgical and patient factors. TKA was associated with higher postoperative opioid requirements than THA. RNB and NA did not diminish total inpatient or 90-day postoperative opioid consumption. The use of acetaminophen, gabapentin, or NSAIDs did not significantly alter inpatient opioid requirements.Cite this article: Bone Joint Open 2020;1-7:398-404.

Using 6 Degrees of Freedom to Systematically Reduce and Fix Distal Radius Fractures.

Six degrees of freedom (6DOF) refers to the freedom of movement of a rigid body in 3-dimensional space. Specifically, the object can move in 3 translations: up/down, left/right, and in/out, and in 3 rotations: pitch, yaw, and roll. In fracture care, the principle of 6DOF can be applied to each individual fracture fragment to help better understand fracture reduction and alignment. In the instance of a distal radius fracture, the 6DOF concept can be utilized to reduce the articular block in a systematic and controlled fashion. The articular block may be displaced in 3 translations-shortened (proximal/distal axis), dorsally translated (volar/dorsal axis), and radially translated (radial/ulnar axis). The articular block may also be displaced in 3 rotations-dorsally tilted (rotated about the radial/ulnar axis or in the sagittal plane), decreased radial inclination (rotated about the volar/dorsal axis or in the coronal plane), and supinated (rotated about the proximal/distal axis or in the axial plane). We present a surgical technique of open reduction and internal fixation of a distal radius fracture through a volar approach where we address the distal segment's instability in 6DOF in a stepwise format.
