Here, we test the null hypothesis that financial distress is not associated with delay of seeking care for hand conditions. Methods: Eighty-seven new patients presenting to the hand clinic for nontraumatic conditions completed our study. Patients completed validated instruments for measuring financial distress, pain catastrophizing, and pain. Questions regarding delay of care were included. The primary outcome was self-reported delay of the current hand clinic visit. Results: Patients who experience high financial distress differed significantly from those who experience low financial distress with respect to age, race, annual household income, and employment status. Those experiencing high financial distress were more likely to report having delayed their visit to the hand clinic (57% vs 30%), higher pain catastrophizing scores (17.7 vs 7.6), and higher average pain in the preceding week (4.5 vs 2.3). After adjusting for age, sex, and pain, high financial distress (adjusted odds ratio [OR] = 4.90) and pain catastrophizing score (adjusted OR = 0.96) were found to be independent predictors of delay. Financial distress was highly associated with annual household income in a multivariable linear regression model. Conclusions: Patients with nontraumatic hand conditions who experience higher financial distress are more likely to delay their visit to the hand clinic. Within health care systems, identification of patients with high financial distress and targeted interventions (eg, social or financial services) may help prevent unnecessary delays in care.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"511 - 518"},"PeriodicalIF":0.0,"publicationDate":"2019-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719866889","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48200776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Assessment of Radiation Protection in Hand-Shielding Products With Mini C-Arm Fluoroscopy","authors":"Matthew B. Cantlon, A. Ilyas","doi":"10.1177/1558944719865937","DOIUrl":"https://doi.org/10.1177/1558944719865937","url":null,"abstract":"Background: Previous studies have highlighted the particular risk of radiation exposure to the surgeon’s hands with intraoperative fluoroscopy. Although evidence exists that shielding equipment for the hands reduces exposure, the extent of protection is not well understood. Therefore, we set out to determine the degree to which radiation exposure to the surgeon’s hands is decreased with hand-shielding products. Methods: An anthropomorphic model was positioned to simulate a surgeon sitting at a hand table. Thermoluminescent dosimeters were placed on the proximal phalanx of each index finger. The right index finger dosimeter was covered with a standard polyisoprene surgical glove (control arm), whereas the left index finger dosimeter was covered with commercially available hand-shielding products (study arm): lead-free metal-oxide gloves, leaded gloves, and radiation-attenuating cream. Mini fluoroscope position, configuration, and settings were standardized. The model was scanned for 15 continuous minutes in each test run, and each comparative arm was run 3 times. Results: The mean radiation dose absorbed by the control and variable dosimeters across all tests was 44.8 mrem (range, 30-54) and 18.6 mrem (range, 14-26), respectively. Each hand-shielding product resulted in statistically lower radiation exposure than a single polyisoprene surgical glove. Conclusions: The mean radiation exposure to the hands was significantly decreased when protected by radiation-attenuating options. Each product individually resulted in a statistically significant decrease in hand exposure compared with the control. We recommend that in addition to efforts to decrease radiation exposure, surgeons consider routine use of hand-shielding products when using mini c-arm fluoroscopy.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"505 - 510"},"PeriodicalIF":0.0,"publicationDate":"2019-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719865937","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44953843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been suggested that persistent ulnar deviation and joint instability influence the durability of PIP silicone arthroplasties. The goal of this study was to evaluate what factors are associated with reoperation after silicone PIP arthroplasty. Methods: We retrospectively evaluated all adult patients who underwent PIP silicone arthroplasty between 2002 and 2016 at one institutional system for inflammatory-, posttraumatic-, and primary degenerative arthritis. After manual chart review, we included 91 patients who underwent 114 arthroplasties. Fingers operated included 14 index, 41 middle, 38 ring, and 21 small fingers. Results: The overall reoperation rate was 14% (n = 16). Non-Caucasian race (P = .040), smoking (P = .022) and PIP silicone arthroplasty for post-traumatic osteoarthritis (P = .021) were associated with reoperation. The 1-, 5- and 10-year implant survival rates were 87%, 85%, and 85%, respectively. Conclusion: Caution should be exercised when considering PIP silicone arthroplasty of the index finger or in patients with post-traumatic osteoarthritis.

This study sought factors associated with attitudes toward aging (measured with the Brief Aging Perceptions Questionnaire [B-APQ]) and studied the relationship of having an age-related disease to magnitude of limitations, pain intensity, patient satisfaction, and patient comfort with completing a questionnaire about attitudes toward aging. We also looked for a subset of questions from B-APQ that maintained the construct validity and internal consistency of B-APQ, without unacceptable flooring or ceiling effects. Methods: A total of 161 upper extremity patients completed the following questionnaires: B-APQ, Patient Health Questionnaire–Short Form, Pain Self-efficacy–Short Form, Pain Catastrophizing Scale–Short Form, Patient-Reported Outcomes Measurement Information System Physical Function–Upper Extremity, pain intensity, satisfaction with the surgeon, and comfort with completing the B-APQ. We created multivariable linear regression models to test for associations. Results: Factors independently associated with less positive perceptions about aging included white race, retired work status, having nonspecific comorbidities, and more catastrophic thinking. Variation in the magnitude of limitations and pain intensity was accounted for by effectiveness of coping strategies rather than attitudes toward aging in particular. A 4-question version of the B-APQ has acceptable performance. Conclusion: Adaptive attitudes toward aging are associated with psychological and social determinants of health. We present a 4-item short form of B-APQ that could be used as a brief measure to assess attitudes toward aging. Interventions to improve adaptiveness to nociception (eg, cognitive behavioral therapy to limit catastrophic thinking) might help with adaptation to age-related changes.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"354 - 361"},"PeriodicalIF":0.0,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719866872","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48197007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There have been reports of a metachronous relationship between trigger thumbs developing in both extremities. Surgeons might consider delaying operative treatment of unilateral trigger thumb due to the concern that contralateral symptoms may develop later in childhood, requiring a second procedure and anesthetic event. Methods: We retrospectively reviewed patients diagnosed with pediatric trigger thumb from 2008 to 2016 at a large pediatric hospital. Data collected included age at presentation and onset, laterality, age and timing of onset of contralateral symptoms, time of index procedure and subsequent procedure (if any), severity of symptoms, previous treatments, range of motion, and birth history. Results: There were 198 patients with pediatric trigger thumb, with 55 patients (28%) presenting with or developing bilateral involvement. Fifty patients (25%) had bilateral involvement upon initial presentation. Five patients (3%) were subsequently diagnosed with contralateral trigger thumb after initial presentation of unilateral trigger thumb. Average time to contralateral trigger thumb development was 12 months after presentation in unilateral patients. Most patients presented with locked flexion contracture with palpable Notta’s nodule. Of the 5 patients who developed contralateral trigger thumbs, three required a second surgery after the index procedure. Conclusions: The vast majority of patients with bilateral trigger thumbs had bilateral involvement upon initial presentation to the pediatric hand clinic. Given the rarity of bilateral symptoms after initial unilateral presentation, we do not recommend delayed surgical intervention for patients with unilateral disease in children over 3 years of age.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"316 - 320"},"PeriodicalIF":0.0,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719864449","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42161380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Major League Baseball’s Health and Injury Tracking System, a prospective injury surveillance system, was used to identify and characterize all hand and wrist injuries sustained by all Major League Baseball (MLB) and Minor League Baseball (MiLB) players during the pre-, regular, and postseason throughout 2011-2016. Injuries were included if they resulted in at least 1 day out of play and were sustained during standard baseball activities. Days missed were defined as the time between injury and the first time in which a player was cleared to return to play. Results: During the study period, there were 4478 hand and 1748 wrist injuries throughout MLB and MiLB, which resulted in a total of 105 246 days out of play. This was equivalent to the length of 575 individual MLB player seasons, and the mean days missed per injury was 17 days. Most injuries were traumatic in nature, with 43% (n = 2672) of players injured after being hit by a baseball that mainly occurred during batting (n = 2521; 40%). Injuries that most frequently required surgical intervention were hook of hamate fractures (72%) and scaphoid fractures (60%). Conclusions: Understanding the epidemiology and impact of hand and wrist injuries in MLB and MiLB players may lead to improved management of these injuries and reduce time away from play. Most importantly, preventive measures and/or enhanced protective gear may be developed to minimize these types of injuries in MLB and MiLB.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"498 - 504"},"PeriodicalIF":0.0,"publicationDate":"2019-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719864450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42676384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Nine arm procurements were performed on deceased tissue-only donors provided by the local organ procurement organization, including two bilateral and five unilateral cases. Technique highlights include using a fishmouth incision through the lateral and medical epicondyles, identification of the neurovascular structures, and disarticulating the elbow joint. Results: Procuring through the elbow provides straightforward anatomy, bypasses the need to cut through bone, and allows tissue allotransplantation teams to achieve procurement, flushing, and packaging within 20 minutes. Conclusions: Procurement through the elbow is a simple procedure that streamlines the process for multi-organ donors by minimizing the time needed for hand allograft procurement. Team coordination and surgical rehearsals are essential for successful hand and upper extremity procurement and allotransplantation.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"391 - 396"},"PeriodicalIF":0.0,"publicationDate":"2019-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719863127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45601810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endoscopic carpal tunnel release has been shown to have comparable outcomes to open release, but open release is considered easier and safer to perform. Previous studies have demonstrated an increase in carpal tunnel volume, regardless of the technique used. However, the mechanism by which this volumetric increase occurs has been debated. Our study will determine through magnetic resonance imaging (MRI) analysis the morphologic changes that occur in both open carpal tunnel release (OCTR) and ECTR, thereby clarifying any morphologic differences that occur as a result of the 2 operative techniques. We hypothesize that there will be no morphologic differences between the 2 techniques. Methods: This was a prospective study to compare the postoperative anatomy of both techniques with MRI. Nineteen patients with clinical and nerve conduction study–confirmed carpal tunnel syndrome underwent either open or endoscopic release. Magnetic resonance imaging was performed preoperatively and 6 months postoperatively in all patients to examine the volume of the carpal tunnel, transverse distance, anteroposterior (AP) distance, divergence of tendons, and Guyon’s canal transverse and AP distance. Results: There was no significant difference in the postoperative morphology of the carpal tunnel and median nerve between OCTR and ECTR at 6-month follow-up on MRI. Conclusion: We conclude that there are no morphologic differences in OCTR and ECTR. It is an increase in the AP dimension that appears to be responsible for the increase in the volume of the carpal tunnel.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"310 - 315"},"PeriodicalIF":0.0,"publicationDate":"2019-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719861711","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46656206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although traditionally conceptualized as partial articular, some volar Barton fractures are complete articular injuries due to a dorsal cortical break in the distal radial metaphysis. While dorsal cortical breaks can affect surgical strategy, they may be difficult to identify on plain radiographs and their epidemiology remains poorly characterized. Some authors have hypothesized an association with osteoporosis; however, this hypothesis remains untested. To better characterize volar Barton fractures, we analyzed fracture geometry on pre-operative computed tomography (CT) scans to: (1) determine the frequency of a dorsal cortical break; and (2) test the null hypothesis that a dorsal cortical break is not associated with age or gender. Methods: We retrospectively reviewed adults with a volar Barton distal radius fracture and an available pre-operative CT who underwent surgical fixation. Using multivariable logistic regression, we assessed whether age or gender was an independent predictor of a dorsal cortical break. Results: Forty patients (mean age 52 years, 57% female) were identified. Including the shaft as a fragment, 32 (80%) had 3 or more discrete fracture fragments. Thirty patients (75%) had a dorsal cortical break. Dorsal cortical breaks were not associated with either age or gender (P > 0.05). Conclusions: Most (75%) patients with volar Barton distal radius fractures had a dorsal cortical break. Dorsal cortical breaks were not statistically associated with age or gender, suggesting these fracture patterns may not be associated with osteoporosis as previously hypothesized.","PeriodicalId":76630,"journal":{"name":"The Hand","volume":"16 1","pages":"303 - 309"},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1558944719862644","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42088149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
