Turnover Tendon Lengthening Does Not Alter Biomechanical Strength of Pronator Teres-to-Extensor Carpi Radialis Brevis Tendon Transfer.

BACKGROUND: The pronator teres (PT) to extensor carpi radialis brevis (ECRB) tendon transfer reestablishes wrist extension. Occasionally, the PT periosteal extension is of suboptimal quality to support a strong transfer. In these instances, turnover lengthening techniques can increase usable tendon length. This study characterized the optimal length of tendon turnover and the effect of lengthening on transfer strength. METHODS: Twenty-seven cadaveric extensor tendons were lengthened using the turnover lengthening technique with 1 to 3 cm of tendon overlap. PT-to-ECRB tendon transfers were performed with native or lengthened ECRB tendons. Tensile testing was used to evaluate stress relaxation and load to failure. RESULTS: The median maximum load to failure increased with increasing overlap length, measuring 35.6 N (quartile 1, 30.2 N; quartile 3, 38.6 N) for 1 cm, 66.0 N (quartile 1, 59.1 N; quartile 3, 74.7 N) for 2 cm, and 96.6 N (quartile 1, 85.9; quartile 3, 114.9 N) for 3 cm of overlap ( P < 0.05). Failure occurred most frequently at the junction of the central overlap and native tendon. Tendons lengthened with 2 and 3 cm of overlap displayed greater stiffness than those with 1 cm ( P < 0.05). Lengthening the ECRB tendon with 2 or 3 cm of overlap did not disrupt the strength or stiffness of subsequent PT-to-ECRB tendon transfers. CONCLUSIONS: Turnover tendon lengthening does not detrimentally affect PT-to-ECRB tendon transfer. Greater overlap lengthening distance confers greater stiffness and resistance to rupture. When the periosteal extension of the PT tendon avulses or is of poor quality, the ECRB tendon can be lengthened using the turnover tendon lengthening technique to facilitate a robust transfer.

A Glass Ceiling in Orthopedic Surgery: Publication Trends by Gender.

Women are underrepresented across the field of orthopedic surgery and may face barriers to academic advancement. Research presentation at national meetings and publication record are important drivers of advancement in academic orthopedic surgery. However, little is known regarding potential gender differences in publication after orthopedic conference research presentation. This investigation analyzed research presentations at the Annual Meeting of the American Academy of Orthopaedic Surgeons in 2016 and 2017. Author gender was determined through a search of institutional and professional networking websites for gender-specific pronouns. Resulting publications were identified using a systematic search of PubMed and Google Scholar databases. A total of 1696 of 1803 (94.1%) abstracts from 2016 to 2017 had identifiable gender for both the first and last authors, with 1213 (71.5%) abstracts ultimately being published. There were no differences in average sample size or level of evidence between genders. Abstracts authored by women were significantly less likely to lead to publication compared with those by men (67.1% vs 72.1%, P=.023), with articles authored by women having a longer median time to publication (median, 20 months [interquartile range, 19] vs 17 months [interquartile range, 15]; P=.003). This discrepancy was most apparent in adult reconstruction, with women having a 15.5% lower rate of publication (55.1% [27/49] vs 70.6% [307/435]; P=.026) and lower publication journal impact factor (2.7±1.4 vs 3.4±3.4, P=.040) than men. Potential reasons for these discrepancies, including disproportionate domestic obligations, inadequate mentorship, and bias against female researchers, should be addressed.

A simple surgical mask modification to pass N95 respirator-equivalent fit testing standards during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has infected hundreds of millions of people resulting in millions of deaths worldwide. While N95 respirators remain the gold standard as personal protective equipment, they are resource-intensive to produce and obtain. Surgical masks, easier to produce and obtain, filter ≥95% submicron particles but are less protective due to a lack of seal around a user's face. This study tested the ability of a simple surgical mask modification using rubber bands to create a seal against particle exposure that would pass N95 standards. METHODS AND FINDINGS: Forty healthcare workers underwent TSI PortaCount mask fit testing using an ASTM Level 1 surgical mask modified with rubber bands. Fit Factor was determined after testing four standard OSHA N95 fit testing scenarios. Performance of the properly-modified surgical mask was compared to that of a poorly-modified surgical mask, an unmodified standard surgical mask, and an N95 respirator. Thirty-one of forty (78%) healthcare workers passed Fit Factor testing using a properly-modified mask. The Fit Factor success rate significantly improved by subsequent test date (p = 0.043), but was not associated with any other participant characteristics. The average Fit Factor score for the properly-modified mask was 151 (SD 65.2), a significantly better fit than the unmodified mask score of 3.8 (SD 3.1, p<0.001) and the poorly-modified mask score of 24.6 (SD 48.4, p<0.001) but significantly lower than a properly fitted N95 score of 199 (SD 4.5, p<0.001).do. CONCLUSIONS: Rubber bands, a low-cost and easily-accessible modification, can improve the seal and protective ability of a standard surgical mask to the level of an N95 respirator. This could mitigate N95 respirator shortages worldwide and provide individuals in under-resourced regions a practical means for increased personal respiratory protection.

The effects of incremental ulnar styloid osteotomies on distal radioulnar joint stability: a biomechanical cadaveric study.

The purpose of this study was to systematically quantify distal radioulnar joint stability with a cadaveric model, using radiographic and joint contact force measurements. Six fresh-frozen cadavers underwent sequential ulnar styloid osteotomies. Posteroanterior and lateral stress radiographs were obtained and joint contact forces and areas were measured. Posteroanterior radiographs showed a significant increase in the distal radioulnar joint gap after osteotomy of the base of the ulnar styloid. Contact force and contact area measurements were not significantly different. We conclude that fractures that involve the ulnar styloid base should be considered for operative fixation when carrying out open reduction and internal fixation of fractures of the distal radius.

Enteroarticular Fistula Following Antibiotic Spacer Placement for a Periprosthetic Joint Infection in a Patient with Chronic Pelvic Discontinuity: A Case Report.

CASE: A 50-year-old man with a history of chronic refractory periprosthetic joint infection following total hip arthroplasty, which had been treated with multiple antibiotic spacers, developed an enteroarticular fistula. He was able to avoid hip disarticulation after undergoing a laparoscopic colectomy with a diverting colostomy and a functional hip resection arthroplasty. At the 1-year follow-up, he was walking independently with crutches and had minimal pain. CONCLUSION: An enteroarticular fistula following total hip arthroplasty is a rare and serious complication. To our knowledge, this is the first reported case that occurred in the setting of an antibiotic spacer. A multidisciplinary team approach is essential for achieving clinical success.

A Prospective Observational Assessment of Unicortical Distal Screw Placement During Volar Plate Fixation of Distal Radius Fractures.

PURPOSE: Although volar plating of the distal radius is performed frequently, the necessity of distal bicortical fixation in the metaphyseal and epiphyseal areas of the distal radius has not been proven. This study aimed primarily to quantify the ability of unicortical distal screws to maintain operative reduction of adult distal radius fractures and secondarily to determine if unicortical screw lengths could be predicted based on anatomical measurements. METHODS: This prospective trial enrolled 75 adult patients undergoing volar locking plate fixation of a unilateral distal radius fracture at a tertiary center. Study inclusion required screw fixation in the distal rows of the plate performed with unicortical screw placement. The primary outcome was maintenance of operative reduction, according to predefined parameters, quantified by comparing initial operative reduction to final reduction after fracture healing. Repeated measures analysis of variance analyzed for systematic change in radiographic parameters between injury, operative, and healed images. Correlation coefficients quantified the relationship of screw lengths with lunate width and other anatomical measurements. RESULTS: Seventy-five patients (mean age, 54 years ± 15 years; 79% women) were enrolled and followed to fracture union. Fracture severity varied and included AO type A (40%), B (12%), and C (48%) fractures. There was no significant change in mean lateral translation, intra-articular gap, intra-articular stepoff, radial inclination, or lateral tilt of the radius between the time of fixation and union for the cohort. Two patients lost reduction (increased dorsal tilt, 10°, 20°, respectively), potentially attributable to provision of unicortical fixation (3%; 95% confidence interval [95% CI], 0%-9%). No extensor tenosynovitis or extensor tendon ruptures occurred. Eighty percent of screws were 18 mm or less and screw lengths were not correlated with lunate width or any other anatomical measurements. CONCLUSIONS: Unicortical distal fixation during volar locking plate fixation effectively maintains operative reductions of distal radius fractures while potentially minimizing the incidence of extensor tendon ruptures.

Floor Effect of PROMIS Depression CAT Associated With Hasty Completion in Orthopaedic Surgery Patients.

BACKGROUND: The Patient Reported Outcomes Measurement Information System (PROMIS) was developed to provide valid, reliable, and standardized measures to gather patient-reported outcomes for many health domains, including depression, independent of patient condition. Most studies confirming the performance of these measures were conducted with a consented, volunteer study population for testing. Using a study population that has undergone the process of informed consent may be differentiated from the validation group because they are educated specifically as to the purpose of the questions and they will not have answers recorded in their permanent health record. QUESTIONS/PURPOSES: (1) When given as part of routine practice to an orthopaedic population, do PROMIS Physical Function and Depression item banks produce score distributions different than those produced by the populations used to calibrate and validate the item banks? (2) Does the presence of a nonnormal distribution in the PROMIS Depression scores in a clinical population reflect a deliberately hasty answering of questions by patients? (3) Are patients who are reporting minimal depressive symptoms by scoring the minimum score on the PROMIS Depression Computer Adaptive Testing (CAT) distinct from other patients according to demographic data or their scores on other PROMIS assessments? METHODS: Univariate descriptive statistics and graphic histograms were used to describe the frequency distribution of scores for the Physical Function and Depression item banks for all orthopaedic patients 18 years or older who had an outpatient visit between June 2015 and December 2016. The study population was then broken into two groups based on whether they indicated a lack of depressive symptoms and scored the minimum score (34.2) on the Depression CAT assessment (Floor Group) or not (Standard Group). The distribution of Physical Function CAT scores was compared between the two groups. Finally, a time-per-question value was calculated for both the Physical Function and Depression CATs and was compared between assessments within each group as well as between the two groups. Bivariate statistics compared the demographic data between the two groups. RESULTS: Physical Function CAT scores in musculoskeletal patients were normally distributed like the distribution calibration population; however, the score distribution of the Depression CAT in musculoskeletal patients was nonnormal with a spike in the floor score. After excluding the floor spike, the distribution of the Depression CAT scores was not different from the population control group. Patients who scored the floor score on the Depression CAT took slightly less time per question for Physical Function CAT when compared with other musculoskeletal patients (floor patients: 11 ± 9 seconds; normally distributed patients: 12 ± 10 seconds; mean difference: 1 second [0.8-1.1]; p < 0.001 but not clinically relevant). They spent a substantially shorter amount of time per question on the Depression CAT (Floor Group: 4 ± 3 seconds; Standard Group: 7 ± 7 seconds; mean difference: 3 [2.9-3.2]; p < 0.001). Patients who scored the minimum score on the PROMIS Depression CAT were younger than other patients (Floor Group: 50 ± 18 SD; Standard Group: 55 ± 16 SD; mean difference: 4.5 [4.2-4.7]; p < 0.001) with a larger percentage of men (Floor Group: 48.8%; Standard Group 40.0%; odds ratio 0.6 [0.6-0.7]; p < 0.001) and minor differences in racial breakdown (Floor Group: white 85.2%, black 11.9%, other 0.03%; Standard Group: white 83.9%, black 13.7%, other 0.02%). CONCLUSIONS: In an orthopaedic surgery population that is given PROMIS CAT as part of routine practice, the Physical Function item bank had a normal performance, but there is a group of patients who hastily complete Depression questions producing a strong floor effect and calling into question the validity of those floor scores that indicate minimal depression. LEVEL OF EVIDENCE: Level II, diagnostic study.

Comparative Morbidity of Cubital Tunnel Surgeries: A Prospective Cohort Study.

PURPOSE: Randomized controlled trials have not identified a superior surgical approach to cubital tunnel syndrome surgery. This study evaluates the early morbidity of open in situ decompression and transposition. METHODS: This prospective cohort study enrolled 125 adult patients indicated for cubital tunnel surgery at a tertiary institution. Exclusion criteria included preoperative use of narcotics and concurrent elbow procedures. In situ decompressions (n = 47) and ulnar nerve transpositions (n = 78) were performed. Data were collected by independent clinicians at 3 postoperative intervals: 1 to 3 weeks, 4 to 8 weeks, and longer than 8 weeks. Postoperative data quantified surgical morbidity: visual analog scale (0-10) surgical site pain, narcotic consumption, patient-reported disability (Levine-Katz, Patient-Reported Elbow Evaluation [PREE] scores). Olecranon paresthesia and wound complications (hematoma, drainage, infection) were recorded. RESULTS: No preoperative differences in age, sex, or the presence of pain existed between the surgical groups. Surgical site pain was not significantly different at any time. Following transposition, a significantly greater percentage of patients were using narcotics at 4 to 8 weeks after surgery and the average total morphine equivalents consumed per patient was significantly greater. Both Levine-Katz and PREE scores indicated greater disability at 1 to 3 and 4 to 8 weeks after transposition, but this significant difference resolved by final follow-up. Olecranon paresthesias occurred after both procedures but were significantly less frequent at 4 to 8 weeks and longer than 8 weeks after decompression. Twelve hematomas occurred following transposition (15%) with 1 requiring operative debridement and 5 hematomas resolved with nonsurgical treatment after in situ decompression (11%). CONCLUSIONS: Ulnar nerve transposition imparts greater surgical morbidity than decompression with greater narcotic consumption, more patient-reported disability up to 8 weeks after surgery, and more persistent olecranon paresthesia. However, most differences in surgical morbidity are transient with resolution after 8 weeks following surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Perioperative Celecoxib and Postoperative Opioid Use in Hand Surgery: A Prospective Cohort Study.

PURPOSE: Prescription opioid abuse is an epidemic in the United States; multimodal analgesia has been suggested as a potential solution to decrease postoperative opioid use. The primary aim of this study was to determine the effect of perioperative celecoxib on opioid intake. Secondary goals were to determine whether perioperative administration of celecoxib decreased postoperative patient-reported pain and whether patient demographic characteristics could predict postoperative pain and opioid intake. METHODS: This prospective cohort study enrolled patients undergoing mass excision or carpal tunnel, trigger finger, or de Quervain release by 1 of 3 fellowship-trained hand surgeons. Patients in the experimental group were given 200 mg celecoxib tablets taken twice a day starting the day before surgery and continued for 5 days after surgery. Both groups received hydrocodone-acetaminophen tablets 5 mg/325 mg as needed after surgery. After surgery, patients completed daily opioid consumption and pain logs for 7 days and underwent a pill count. Outcomes included morphine milligram equivalents (MME) consumed and postoperative pain. RESULTS: A total of 123 patients were enrolled: 68 control patients and 54 celecoxib patients. Fifty (74%) and 37 (69%) patients, respectively, completed the study. Overall, the median number of MMEs consumed was 25 (range, 0-330). During the first postoperative week, patients in the celecoxib and control groups were similar with respect to postoperative pain experienced (median visual analog scale score, 2.0 vs 1.4, respectively) and amount of opioid taken (median MMEs = 30 vs 20, respectively). CONCLUSIONS: Patients taking perioperative celecoxib had similar postoperative pain and opioid intake compared with patients not prescribed celecoxib in the study. Regardless of study group, 4 to 10 hydrocodone tablets were sufficient to control postoperative pain for most patients undergoing soft tissue ambulatory hand surgery. This may be the result of the limited duration and mild nature of pain after outpatient elective hand surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Functional Outcomes of Thumb Trapeziometacarpal Arthrodesis With a Locked Plate Versus Ligament Reconstruction and Tendon Interposition.

PURPOSE: To compare standardized functional and patient-reported early outcomes following trapeziometacarpal arthrodesis (TMA) using a locking cage plate construct with trapezial excision, ligament reconstruction, and tendon interposition (LRTI). METHODS: This prospective cohort enrolled 50 consecutive patients with trapeziometacarpal osteoarthritis undergoing TMA or LRTI. Demographic data, objective measurements, Sollerman function testing, and patient-reported outcomes were collected before surgery and at various time intervals up to 12 months after surgery. The study was powered to detect a minimally clinically important difference on the Michigan Hand Questionnaire between groups at 12 months. To account for selection bias, we performed between-group statistical analysis of the magnitude of change from preoperative to postoperative data. All complications were recorded. RESULTS: There were no significant differences in the amount of change in grip or pinch strength, patient-reported outcomes, or functional hand testing between TMA and LRTI. The TMA group had significantly increased thumb tip opposition distance. The TMA group was complicated by a 26% overall nonunion rate of which 8% were symptomatic. The LRTI group (Wagner incision) had a significantly increased incidence of superficial branch of the radial nerve paresthesia. The incidence of complications was similar between operative groups, but revision surgery was more common after TMA. CONCLUSIONS: Compared with LRTI, TMA failed to demonstrate superior improvement in strength, standardized functional performance, or patient-reported function and is associated with an increased likelihood of revision surgery in the first 12 months. Trapeziometacarpal arthrodesis with a locking plate and screw construct does not ensure union, although most radiographic nonunions were asymptomatic. Wagner incisions are associated with a significantly increased incidence of superficial branch of the radial nerve paresthesia compared with dorsal trapeziometacarpal exposure. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Long-Term Effectiveness of Repeat Corticosteroid Injections for Trigger Finger.

PURPOSE: To quantify the long-term success of repeat injections for trigger fingers and to identify predictors of treatment outcomes. METHODS: This retrospective case series analyzed 292 repeat corticosteroid injections for trigger fingers administered by hand surgeons at a single tertiary center between January 2010 and January 2013. One hundred eighty-seven patients (64%) were female, 139 patients (48%) had multiple trigger fingers, and 63 patients (22%) were diabetic. The primary outcome, treatment failure, was defined as receiving a subsequent injection or surgical treatment. Patients without either documented failure or a return office visit in 2015 or 2016 were surveyed by telephone to determine if they had required subsequent treatment. Kaplan-Meier analyses with log-rank testing assessed the median time to treatment failure and the effect of demographic and disease-specific characteristics on injection success rate and predictors of injection outcome (success vs failure) were assessed with multivariable logistic regression. RESULTS: Second injections provided long-term treatment success in 39% (111 of 285) of trigger fingers with 86 receiving an additional injection and 108 ultimately undergoing surgical release. Thirty-nine percent (24 of 62) of third injections resulted in long-term success, with 22 receiving an additional injection, and 23 ultimately undergoing surgery. Median times-to-failure for second and third injections were 371 and 407 days, respectively. Success curves did not differ significantly according to any patient or disease factor. Logistic regression identified that advancing patient age and injection for trigger thumb were associated with success of second injections. CONCLUSIONS: Thirty-nine percent of second and third corticosteroid injections for trigger finger yield long-term relief. Although most patients ultimately require surgical release, 50% of patients receiving repeat trigger injections realize 1 year or more of symptomatic relief. Repeat injections of trigger fingers should be considered in patients who prefer nonsurgical treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Preferences for Shared Decision Making in Older Adult Patients With Orthopedic Hand Conditions.

PURPOSE: The practice of medicine is shifting from a paternalistic doctor-patient relationship to a model in which the doctor and patient collaborate to decide optimal treatment. This study aims to determine whether the older orthopedic population desires a shared decision-making approach to care and to identify patient predictors for the preferred type of approach. METHODS: This cross-sectional investigation enrolled 99 patients, minimum age 65 years, at a tertiary hand specialty practice between March and June 2015. All patients completed the Control Preferences Scale, a validated system that distinguishes among patient preferences for patient-directed, collaborative, or physician-directed decision making. Bivariate and logistic regression analyses assessed associations among demographic data; clinic encounter variables such as familiarity with provider, trauma, diagnosis, and treatment decision; and the primary outcome of Control Preferences Scale preferences. RESULTS: A total of 81% of patients analyzed preferred a more patient-directed role in decision making; 46% of the total cohort cited a collaborative approach as their most preferred treatment approach. Sixty-seven percent cited the most physician-directed approach as their least preferred model of decision making. In addition, 49% reported that spending more time with their physician to address questions and explain the diagnosis would be most useful when making a health care decision and 73% preferred additional written informational material. Familiarity with the provider was associated with being more likely to prefer a collaborative approach. CONCLUSIONS: Older adult patients with symptomatic upper-extremity conditions desire more patient-directed roles in treatment decision making. Given the limited amount of reliable information obtained independently outside the office visit, our data suggest that written decision aids offer an approach to shared decision making that is most consistent with the preferences of the older orthopedic patient. CLINICAL RELEVANCE: This study quantifies older adults' desire to participate in decision making when choosing among treatments for hand conditions.
