Diagnostic Criteria for Symptomatic Neuroma.

INTRODUCTION: After nerve injury, disorganized or incomplete nerve regeneration may result in a neuroma. The true incidence of symptomatic neuroma is unknown, and the diagnosis has traditionally been made based on patient history, symptoms, physical examination, and the anatomic location of pain, along with response to diagnostic injection. There are no formally accepted criteria for a diagnosis of neuroma. MATERIALS AND METHODS: A literature search was performed to identify articles related to neuroma: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and Pubmed, Embase, and the Cochrane Library were searched for all relevant articles pertaining to neuroma. Articles were screened by title and abstract for relevance. If an article was considered potentially relevant, the full article was reviewed. After consideration, 50 articles were included in this systematic review. RESULTS: No previous articles directly addressed diagnostic criteria for symptomatic neuroma. Factors related to neuroma diagnosis gleaned from previous studies include pain and cold intolerance (patient history), positive Tinel sign or diminished 2-point discrimination (physical examination findings), response to diagnostic nerve block, and presence of neuroma on diagnostic imaging (ultrasound or magnetic resonance imaging). Based on literature review, the importance and number of references, as well as clinical experience, we propose criteria for diagnosis of symptomatic neuroma. To receive a diagnosis of symptomatic neuroma, patients must have (1) pain with at least 3 qualifying "neuropathic" characteristics, (2) symptoms in a defined neural anatomic distribution, and (3) a history of a nerve injury or suspected nerve injury. In addition, patients must have at least 2 of the following 4 findings: (1) positive Tinel sign on examination at/along suspected nerve injury site, (2) tenderness/pain on examination at/along suspected nerve injury site, (3) positive response to a diagnostic local anesthetic injection, and (4) ultrasound or magnetic resonance imaging confirmation of neuroma. CONCLUSIONS: The diagnosis of neuroma is based on a careful history and physical examination and should rely on the proposed criteria for confirmation. These criteria will be helpful in more precisely defining the diagnosis for clinical and research purposes.

Decision Aid for Trapeziometacarpal Arthritis: A Randomized Controlled Trial.

PURPOSE: Decision aids increase patient participation in decision making and reduce decision conflict. The goal of this study was to evaluate the effect of a decision aid prior to the appointment, upon decisional conflict measured immediately after the visit relative to usual care. We also evaluated other effects of the decision aid over time. METHODS: In this randomized controlled trial, we included 90 patients seeking the care of a hand surgeon for trapeziometacarpal (TMC) arthritis for the first time. Patients were randomly assigned to receive either usual care (an informational brochure) or an interactive Web-based decision aid. At enrollment, consult duration was recorded, and patients completed the following measures: (1) Decisional Conflict Scale; (2) Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH); (3) pain intensity; (4) Physical Health Questionnaire (PHQ-2); (5) satisfaction with the visit; and (6) Consultation And Relational Empathy (CARE) scale. At 6 weeks and 6 months, patients completed: (1) pain intensity measure; (2) Decision Regret Scale; and (3) satisfaction with treatment. We also recorded changes in treatment and provider. RESULTS: Patients who reviewed the interactive decision aid prior to visiting their hand surgeon had less decisional conflict at the end of the visit. Other outcomes were not affected. CONCLUSIONS: Use of a decision aid prior to a first-time visit for TMC led to a measurable reduction in decision conflict. Decision aids make people seeking care for TMC arthritis more comfortable with their decision making. Future research might address the ability of decision aids to reduce surgeon-to-surgeon variation, resource utilization, and dissatisfaction with care CLINICAL RELEVANCE: Surgeons should consider the routine use of decision aids to reduce decision conflict.

Longitudinal Microsurgery Laboratory Training during Hand Surgery Fellowship.

BACKGROUND: Laboratory training courses have traditionally offered an attractive method to learn microsurgery in a low-risk environment. However, courses are often limited by cost, accessibility, and their one-time, nonlongitudinal nature. Our aims were to (1) describe our institution's microsurgical training course for hand surgery fellows, which is longitudinal and integrated within our fellowship curriculum and (2) investigate how this course affects the microsurgical confidence and competence of trainees throughout their fellowship year. METHODS: All hand fellows who trained in our 1-year combined hand surgery fellowship from 2016 through 2018 participated in this study. Baseline data on the type and duration of residency training, previous microsurgery experience and self-reported confidence, knowledge, and interest in microsurgery were recorded. Self-reported scores were documented using a continuous scale ranging from 0 to 10. An initial 3-day laboratory course combining the use of didactic teaching, a nonliving synthetic model, and a live rat model was conducted. Repeat laboratory training occurred thereafter at 6 and 12 months. At the end of each session, fellows repeated the baseline questionnaire and faculty assessed their microsurgical competence using a standardized global rating scale (GRS). RESULTS: A total of six fellows (2 years) were enrolled. At the end of the initial course, there was a statistically significant increase in mean self-reported confidence in microsurgery from 4.3 to 6.2 and knowledge from 4.7 to 6.5. Mean scores in interest were unchanged, from 9.2 to 9.3. There was also an increase in mean GRS score from day 3 to months 6 and 12. CONCLUSION: A longitudinal microsurgical training course integrated within a hand surgery fellowship is associated with increased confidence and microsurgical skill. This study describes our approach and its feasibility.

Hand Posturing Is a Nonverbal Indicator of Catastrophic Thinking for Finger, Hand, or Wrist Injury.

BACKGROUND: Prior research documents that greater psychologic distress (anxiety/depression) and less effective coping strategies (catastrophic thinking, kinesophobia) are associated with greater pain intensity and greater limitations. Recognition and acknowledgment of verbal and nonverbal indicators of psychologic factors might raise opportunities for improved psychologic health. There is evidence that specific patient words and phrases indicate greater catastrophic thinking. This study tested proposed nonverbal indicators (such as flexion of the wrist during attempted finger flexion or extension of uninjured fingers as the stiff and painful finger is flexed) for their association with catastrophic thinking. QUESTIONS/PURPOSES: (1) Do patients with specific protective hand postures during physical examination have greater pain interference (limitation of activity in response to nociception), limitations, symptoms of depression, catastrophic thinking (protectiveness, preparation for the worst), and kinesophobia (fear of movement)? (2) Do greater numbers of protective hand postures correlate with worse scores on these measures? METHODS: Between October 2014 and September 2016, 156 adult patients with stiff or painful fingers within 2 months after sustaining a finger, hand, or wrist injury were invited to participate in this study. Six patients chose not to participate as a result of time constraints and one patient was excluded as a result of inconsistent scoring of a possible hand posture, leaving 149 patients for analysis. We asked all patients to complete a set of questionnaires and a sociodemographic survey. We used Patient Reported Outcomes Measurement Information System (PROMIS) Depression, Upper Extremity Physical Function, and Pain Interference computer adaptive test (CAT) questionnaires. We used the Abbreviated Pain Catastrophizing Scale (PCS-4) to measure catastrophic thinking in response to nociception. Finally, we used the Tampa Scale of Kinesophobia (TSK) to assess fear of movement. The occurrence of protective hand postures during the physical examination was noted by both the physician and researcher. For uncertainty or disagreement, a video of the physical examination was recorded and a group decision was made. RESULTS: Patients with one or more protective hand postures did not score higher on the PROMIS Pain Interference CAT (hand posture: 59 [56-64]; no posture: 59 [54-63]; difference of medians: 0; p = 0.273), Physical Function CAT (32 ± 8 versus 34 ± 8; mean difference: 2 [confidence interval {CI}, -0.5 to 5]; p = 0.107), nor the Depression CAT (48 [41-55] versus 48 [42-53]; difference of medians: 0; p = 0.662). However, having at least one hand posture was associated with a higher degree of catastrophic thinking (PCS scores: 13 [6-26] versus 10 [3-16]; difference of medians: 3; p = 0.0104) and a higher level of kinesophobia (TSK: 40 ± 6 versus 38 ± 6; mean difference: -2 [CI, -4 to -1]; p = 0.0420). Greater catastrophic thinking was associated with a greater number of protective hand postures on average (rho: 0.20, p = 0.0138). CONCLUSIONS: Protective hand postures and (based on prior research) specific words and phrases are associated with catastrophic thinking and kinesophobia, less effective coping strategies that hinder recovery. Surgeons can learn to recognize these signs and begin to treat catastrophic thinking and kinesophobia starting with compassion, empathy, and patience and be prepared to add formal support (such as cognitive-behavioral therapy) to help facilitate recovery. LEVEL OF EVIDENCE: Level III, diagnostic study.

Is Physician Empathy Associated With Differences in Pain and Functional Limitations After a Hand Surgeon Visit?

BACKGROUND: In prior work we demonstrated that patient-rated physician empathy was the strongest driver of patient satisfaction after a visit to an orthopaedic hand surgeon. Data from the primary care setting suggest a positive association between physician empathy and clinical outcomes, including symptoms of the common cold. It is possible that an empathic encounter could make immediate and measureable changes in a patient's mindset, symptoms, and functional limitations. QUESTIONS/PURPOSES: (1) Comparing patients who rated their physicians as perfectly empathic with those who did not, is there a difference in pre- to postvisit change in Patient Reported Outcome Measurement Information System (PROMIS) Upper Extremity Function scores? (2) Do patients who gave their physicians perfectly empathic ratings have a greater decrease in pre- to postvisit change in Pain Intensity, PROMIS Pain Interference, and PROMIS Depression scores? METHODS: Between September 2015 and February 2016, based on the clinic patient flow, 134 new patients were asked to participate in this study. Eight patients were in a rush to leave the surgeon's office, which left us with a final cohort of 126 patients. Directly before and directly after the appointment with their physician, patients were asked to complete three PROMIS Computerized Adaptive Tests (CAT; Upper Extremity Function, Pain Interference, and Depression) as well as an ordinal rating of pain intensity. After the visit, participants were asked to rate their physician using the Consultation And Relational Empathy (CARE) measure. Based on prior experience, we dichotomized the CARE score anticipating a substantial skew: 54 patients (43%) rated their physician perfectly empathic. RESULTS: Between patients who rated physicians as perfectly empathic and those who did not, there was no difference in the pre- to postvisit change in PROMIS Upper Extremity Function CAT score (perfect empathy: 0.84 ± 2.94; less than perfect empathy: -0.23 ± 3.12; mean difference: 0.23; 95% confidence interval [CI], -0.31 to 0.77; p = 0.054). There was a small decrease in Pain Intensity (perfect empathy: -0.96 ± 2.08; less than perfect empathy: -0.33 ± 1.03; mean difference: -0.60; 95% CI, -0.88 to -0.32; p = 0.028). There were no differences in PROMIS Pain Interference score (perfect empathy: -1.33 ± 2.85; less than perfect empathy: -1.37 ± 3.12; mean difference: -1.35; 95% CI, -1.88 to -0.83; p = 0.959) or PROMIS Depression scores (perfect empathy: -1.51 ± 4.02; less than perfect empathy : -1.21 ± 3.83; mean difference: -1.34; 95% CI, -2.03 to -0.65; p = 0.663). CONCLUSIONS: A single visit with a surgeon rated perfectly empathic is not associated with change in upper extremity-specific limitations or coping mechanisms or a noticeable change in pain scores during the visit, as these differences were below the minimum clinically important difference. Future research should address the influence of empathy on patient-reported outcomes and physician empathy over time in contrast to a single office visit. LEVEL OF EVIDENCE: Level II, prognostic study.

Symptomatic Neuroma Following Initial Amputation for Traumatic Digital Amputation.

PURPOSE: We tested the null hypothesis that no factors are independently associated with the development of symptomatic neuroma after traumatic digital amputation. METHODS: We performed a retrospective review of 1,083 patients who underwent revision amputation for traumatic digital amputation; we excluded those undergoing replantation or revascularization. Patients who developed a painful neuroma during follow-up were identified with a minimum follow-up of 1 week and a median of 3.3 months. We calculated the rate of developing a painful neuroma as a proportion of the total number of patients and performed multivariable logistic regression analysis to identify factors independently associated with its development. RESULTS: Of 1,083 patients, 71 (6.6%) developed a symptomatic neuroma. Mean time to diagnosis was 6.4 months. A total of 47 patients (66%) underwent surgery for painful neuroma. Mean time to surgical intervention was 11 months. Index finger injury and avulsion injury mechanism were significantly associated with a higher risk for symptomatic neuroma. CONCLUSIONS: Approximately 1 in 15 patients will develop a symptomatic neuroma after traumatic digital amputation and more than half of these patients will undergo revision surgery for neuroma, with a mean time to operative intervention of 11 months. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Gradual Onset Diseases: Misperception of Disease Onset.

PURPOSE: Gradual onset diseases (eg, carpal tunnel syndrome, cubital tunnel syndrome, and trapeziometacarpal arthrosis) tend to go unnoticed for years. When a slowly progressive disease transitions from asymptomatic to symptomatic, it may seem like an acute event. The primary aim of this study was to determine the percentage of patients who perceive the slowly progressive disease as having started within 1 year. We also hypothesized that (1) there would be no factors associated with perception of an onset of disease within 1 year, more specifically among patients with advanced disease; and (2) there would be no difference in a decision to pursue operative treatment between patients who perceived the onset of the disease to be recent and those who perceived it to be long-standing. METHODS: In this retrospective study, we reviewed the medical records of 732 patients newly diagnosed with carpal tunnel syndrome (n = 114), cubital tunnel syndrome (n = 276), or trapeziometacarpal arthrosis (n = 342), for the onset of symptoms. Multiple factors were assessed for (1) association with perception of disease onset within 1 year, and (2) choice for operative treatment in bivariate and multivariable analyses. RESULTS: A total of 69% of all subjects and 68% of patients with advanced disease perceived the disease as having started within 1 year. A perceived provocation (such as an injury or surgery) was associated with a perception of recent onset. A decision to pursue operative treatment was not different between the 2 groups. CONCLUSIONS: Slowly progressive diseases are often misperceived as relatively new. CLINICAL RELEVANCE: Effective communication strategies are important to ensure that people make choices consistent with their values and not based on misconceptions.

Patients Transferred for Upper Extremity Amputation: Participation of Regional Trauma Centers.

PURPOSE: Level-I trauma centers are required to provide hand and microsurgery capability at all times. We examined transfers to our center to better understand distant patient referrals and, indirectly, study referrals in our region. METHODS: Records were reviewed from 2010 to 2015 to evaluate patients transferred to our level-I institution for upper extremity amputation. Patients were referred from 6 states to our institution over this period. We measured the straight-line distance from each patient's transferring facility to our facility and compared this distance with the straight-line distances from the zip code of the transferring facility to the zip code of each level-I trauma center. RESULTS: We had data for 250 transferred patients (91% male, 9% female). For 110 patients (44%), our hospital was the nearest level-I trauma center; however, for the remaining 140 patients (56%), other level-I trauma facilities were located closer to the referring hospital. Among these 140 patients, the mean distance of the referring facility to the nearest level-I trauma center (30 miles; SD, 27) was significantly different from the mean distance of the referring facility to our facility (71 miles; SD, 60). A median of 4 (range, 1-10) level-I trauma centers were bypassed before patients arrived at our center. Medicaid and "self-pay" patients were more likely to be transferred to our facility. CONCLUSIONS: Fifty-six percent of patients transferred to our hospital for upper extremity amputation had a level-I trauma center closer to their injury. Patients with upper extremity amputation are referred to our regional center despite the proximity of closer level-I trauma centers. This suggests that regional microsurgery expertise does not correlate with level-I trauma designation, and establishment of designated microsurgery centers and formal referral guidelines may be beneficial for management of these difficult injuries. CLINICAL RELEVANCE: We believe that this study further supports the need for formal designation of regional centers of expertise for microsurgical hand trauma.

Reoperation After Combined Injury of the Index Finger: Repair Versus Immediate Amputation.

PURPOSE: To identify factors associated with unplanned reoperation of severely injured index fingers and to address the number of amputations after initial repair. METHODS: In this retrospective study, we included all patients older than 18 years of age who had repair or immediate amputation for combined index finger injury at 2 level I trauma centers and 1 community hospital tied to a level I trauma center between January 2004 and February 2014. Twelve patients were excluded because of inadequate follow-up. Bivariate and multivariable analyses sought factors associated with unplanned reoperation after repair and immediate amputation. RESULTS: Among 114 patients with combined injury, 75 were treated with repair and 39 with immediate amputation. A total of 41 patients had an unplanned reoperation, 33 after repair (44%) and 8 after immediate amputation (21%). In multivariable analysis, patients who had a reoperation for fingers other than the index finger were at risk for unplanned reoperation after repair. Women were more likely to have an unplanned reoperation than men, and patients who had a ray amputation were at risk for unplanned reoperation after immediate amputation. Six patients (18%) had amputation after initial repair. CONCLUSIONS: Surgeons may counsel patients that they are twice as likely to have an unplanned reoperation after a repair for combined injury of the index finger compared with an immediate amputation. Unplanned reoperations were more common among patients with injuries involving multiple fingers. Effective shared decision making is particularly important in this setting given that 1 in 5 repaired index fingers were eventually amputated. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Evaluation of the Seesaw Test as New Diagnostic Test for Thumb CMC Osteoarthritis.

BACKGROUND: The seesaw test consists of flexion and extension of the thumb metacarpal on the trapezium, with continuous axial pressure to keep the metacarpal base reduced in the carpometacarpal (CMC) joint. We aim to evaluate this maneuver compared with the grind test. METHODS: We prospectively enrolled 80 participants from March 2017 to March 2018 at a single institution, excluding those who had previous thumb surgery or pathology. Each participant underwent both seesaw and grind tests by 2 independent examiners. We included 24 patients with a mean age of 73 years in the CMC osteoarthritis group (Eaton stages 2-4) and 44 patients with a mean age of 66 years in the control group (Eaton stages 0 and 1). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and multirater κ measure. RESULTS: The seesaw test had a higher sensitivity than the grind test (42%-71% vs 13%-17%), but a lower specificity (82%-86% vs 91%-98%). The PPV was more consistent between examiners for the seesaw test (63%-68% vs 42%-80%), and the NPV was higher (73%-84% vs 66%-68%). There was a slight agreement between the attending surgeon and the fellow performing the grind test (κ = 0.08) and a moderate agreement between the attending surgeon and the fellow performing the seesaw test (κ = 0.59). CONCLUSIONS: The seesaw test is superior to the grind test, with a much higher sensitivity, slightly lower specificity, more consistent PPV, and slightly higher NPV. Therefore, the seesaw test could be a valuable addition or even replacement for the grind test, and we recommend considering it in daily practice.

Reoperation After Operative Fixation of Proximal Interphalangeal Joint Fractures.

Background: The purpose of this study was to determine the reoperation rate and what factors are associated with reoperation of proximal interphalangeal (PIP) joint fractures. Methods: We identified 161 surgically treated PIP joint fractures between 2004 and 2015 at 2 academic medical systems. Demographic, injury, radiographic, and treatment data that might be associated with reoperation were collected. Bivariate analysis was performed. Factors identified during bivariate analysis with a P < .10 were entered into a multivariable logistic regression analysis. Results: Of the 161 fingers, 25 underwent revision surgery. Open fracture was independently associated with revision surgery. The most common indication for reoperation was joint stiffness (35%). In a subanalysis of 111 closed fractures, no factors were associated with revision surgery. Conclusions: Soft tissue injury is a major factor in reoperation after PIP joint fracture dislocation. Specific attention should be paid to persistent subluxation because this may predispose to early arthrosis.

Patient Transfer for Hand and Upper Extremity Injuries: Diagnostic Accuracy at the Time of Referral.

BACKGROUND: Local health care facilities are often unequipped to treat complex upper extremity injuries, and patients are therefore transferred to designated trauma centers. This study describes the characteristics of patients transferred to a Level I trauma center for hand and upper extremity injuries and to investigate the accuracy of the provided diagnosis at the time of referral. METHODS: Adult patients transferred from outside facilities to the authors' Level I trauma center by means of direct contract with the on-call fellow for the care of hand and upper extremity injuries were identified. Patient- and injury-related information was prospectively collected at the time of referral before patient transfer, and again following diagnostic evaluation by a hand surgeon at the authors' institution. RESULTS: Sixty-three patients were transferred to the authors' hand surgery service from outside facilities after direct contact with the on-call fellow. Most patients were referred by emergency medicine physicians [n = 47 (76 percent)], followed by midlevel emergency department providers (physician assistant or nurse practitioner) [n = 12 (19 percent)] or hand surgeons [n = 3 (5 percent)]. Six patients were transferred directly from a Level I trauma center. Twenty-one transferred patients (33 percent) had an inaccurate diagnosis at the time of referral. Factors associated with an inaccurate diagnosis included trauma level of the referring hospital and diagnoses of infection or dysvascularity. CONCLUSIONS: The diagnostic accuracy for hand injuries transferred from outside facilities by means of provider-to-provider communication is imperfect, and some injuries are misdiagnosed. Hand surgeons should continue to improve the triage and transfer process for patients with acute hand surgery injuries. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, IV.

Five Essential Principles for First Web Space Reconstruction in the Burned Hand.

BACKGROUND: Burn injuries commonly affect the hand, and the development of adduction contractures of the first web space is frequent and deleterious, both functionally and aesthetically. Many corrective techniques and algorithmic approaches have been described to treat this problem, but there is no consensus on the optimal management. METHODS: A retrospective review at a single high-volume pediatric burn center was undertaken to evaluate the clinical course of these patients. All pediatric patients undergoing initial release of burn scar contracture of the first web space from 2005 through 2015 were included in a retrospective cohort study. RESULTS: The authors identified 40 patients with 57 burned hands. The initial approach to management was variable. Z-plasty or other local flap was the first technique used in 28 hands (49 percent), split-thickness skin graft in 19 hands (33 percent), full-thickness skin graft in seven hands (12 percent), groin flaps in two hands (4 percent), and a reverse radial forearm flap in one hand (2 percent). The mean numbers of total reconstructive procedures per hand including the initial procedure were as follows: groin flap, 4.0; full-thickness skin graft, 3.1; split-thickness skin graft, 2.1; Z-plasty, 1.4; and reverse radial forearm flap, 1.0. CONCLUSIONS: Successful reconstruction of the first web space must be addressed in the context of the entire hand. It is the authors' preference to use split-thickness skin grafting whenever a skin deficiency is present-only then should leading edge contractures be addressed with Z-plasty. Based on their experience, the authors recommend five principles that are essential to successfully treat postburn contractures of the first web space. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Postoperative Dorsal Proximal Interphalangeal Joint Subluxation in Volar Base Middle Phalanx Fractures.

Introduction This study was designed to assess factors associated with postoperative dorsal proximal interphalangeal (PIP) joint subluxation after operative treatment of volar base middle phalanx fractures. Our second purpose was to study the association between postoperative dorsal subluxation with postoperative arthritis. Materials and Methods We identified 44 surgically treated volar base PIP joint fractures with available pre- and postoperative radiographs between 2002 and 2015 at two academic medical systems with a median follow-up of 3.5 months. Demographic, injury, radiographic, and treatment data that might be associated with postoperative dorsal subluxation were collected. Three hand surgeons independently assessed subluxation and arthritis on radiographs. Bivariate analysis was performed to analyze our two study purposes. Results Six of 44 (14%) had postoperative dorsal subluxation after initial surgery. Bivariate analysis showed no factors with statistically significant association with postoperative subluxation, assessed independently by three hand surgeons on radiographs. Fifty per cent of the joints with postoperative arthritis had postoperative subluxation compared with 21% of joints without postoperative subluxation. No significant association was found between postoperative dorsal subluxation with postoperative arthritis. Conclusion The association of persistent subluxation and early arthrosis in dorsal PIP joint fracture dislocations needs further study. At this time, it is unclear in what ways persistent subluxation or arthrosis affects the rate of reoperation. Level of Evidence This is a therapeutic level IV study.

Factors Associated With Radiographic Trapeziometacarpal Arthrosis in Patients Not Seeking Care for This Condition.

BACKGROUND: A common adage among hand surgeons is that the symptoms of trapeziometacarpal (TMC) arthrosis vary among patients independent of the radiographic severity. We studied factors associated with radiographic severity of TMC arthrosis, thumb pain, thumb-specific disability, pinch strength, and grip strength in patients not seeking care for TMC arthrosis. Our primary null hypothesis was that there are no factors independently associated with radiographic severity of TMC arthrosis according to the Eaton classification among patients not seeking care for TMC arthrosis. METHODS: We enrolled 59 adult patients not seeking care for TMC arthrosis. We graded patients' radiographic TMC arthrosis and asked all patients to complete a set of questionnaires: demographic survey, pain scale, TMC joint arthrosis-related symptoms and disability questionnaire (TASD), and a depression questionnaire. Metacarpophalangeal hyperextension and pinch and grip strength were measured, and the grind test and shoulder sign were performed. RESULTS: Older age was the only factor associated with more advanced radiographic pathophysiology of TMC arthrosis. One in 5 patients not seeking care for TMC arthrosis experienced thumb pain; no factors were independently associated with having pain or limitations related to TMC arthrosis. Youth and male sex were associated with stronger pinch and grip strength. CONCLUSIONS: There are a large number of patients with relatively asymptomatic TMC arthrosis. Metacarpophalangeal hyperextension and female sex may have a relationship with symptoms, but further study is needed. Our data support the concept that TMC arthrosis does not correlate with radiographic arthrosis.

Variation in Nonsurgical Treatment Recommendations for Common Upper Extremity Conditions.

BACKGROUND: In orthopaedic surgery, there is known surgeon-to-surgeon variation in recommendations for surgery. Variation in recommendations for nonsurgical treatment of common upper extremity conditions for which surgery is discretionary remains unclear. METHODS: One hundred eighty-three surgeons were included after completing six questions on six scenarios of upper extremity conditions regarding nonsurgical treatment recommendations. For one scenario, we measured the influence of reading a summary of preferred practice before making recommendations. RESULTS: Variation in nonsurgical treatment recommendations was observed between surgeons and between upper extremity conditions. Surgeons that reviewed a decision support paragraph were more likely to opine that surgery would eventually be beneficial. DISCUSSION: The notable variation in nonsurgical treatment recommendations indicates a substantial influence of surgeon bias in decision-making. To help ensure that decisions are consistent, surgeons may benefit from decision support and guidelines to help limit practice variation.

Do Patient Preferences Influence Surgeon Recommendations for Treatment?

BACKGROUND: When the best treatment option is uncertain, a patient's preference based on personal values should be the source of most variation in diagnostic and therapeutic interventions. Unexplained surgeon-to-surgeon variation in treatment for hand and upper extremity conditions suggests that surgeon preferences have more influence than patient preferences. METHODS: A total of 184 surgeons reviewed 18 fictional scenarios of upper extremity conditions for which operative treatment is discretionary and preference sensitive, and recommended either operative or non-operative treatment. To test the influence of six specific patient preferences the preference was randomly assigned to each scenario in an affirmative or negative manner. Surgeon characteristics were collected for each participant. RESULTS: Of the six preferences studied, four influenced surgeon recommendations. Surgeons were more likely to recommend non-operative treatment when patients; preferred the least expensive treatment (adjusted OR, 0.82; 95% CI, 0.71 - 0.94; P=0.005), preferred non-operative treatment (adjusted OR, 0.82; 95% CI, 0.72 - 0.95; P=0.006), were not concerned about aesthetics (adjusted OR, 1.15; 95% CI, 1.0 - 1.3; P=0.046), and when patients only preferred operative treatment if there is consensus among surgeons that operative treatment is a useful option (adjusted OR, 0.78; 95% CI, 0.68 - 0.89; P<0.001). CONCLUSION: Patient preferences were found to have a measurable influence on surgeon treatment recommendations though not as much as we expected-and surgeons on average interpreted surgery as more aesthetic. This emphasizes the importance of strategies to help patients reflect on their values and ensure their preferences are consistent with those values (e.g. use of decision-aids).

The Incidence of Arthroplasty After Initial Arthroscopy for Trapeziometacarpal Arthrosis.

BACKGROUND: It remains unclear how many patients undergo secondary surgery after initial arthroscopy for trapeziometacarpal (TMC) arthrosis. We studied the factors related to secondary TMC arthroplasty after TMC arthroscopy. We also examined secondary questions of: (1) what percentage of patients underwent secondary TMC arthroplasty; and (2) how much time elapsed from initial arthroscopy to arthroplasty. METHODS: In this retrospective study, we included all adult patients who were treated with arthroscopy of the TMC joint at 2 level I hospitals and affiliates. Factors were assessed for their independent association with secondary TMC arthroplasty using bivariate and multivariable analyses. RESULTS: Fourteen of 84 (17%) thumbs underwent secondary TMC arthroplasty an average of 11 months after the initial arthroscopy. Synovectomy alone and smoking tobacco were independently associated with secondary TMC arthroplasty when compared with arthroscopic (partial) trapeziectomy with additional tendon interposition or allograft. CONCLUSIONS: This study demonstrated that 1 in 6 thumbs underwent secondary TMC arthroplasty, an average of 11 months after the initial arthroscopy. Coupling arthroscopy with partial trapeziectomy, interposition, or extension osteotomy may be a preferable strategy to isolated synovectomy. In addition, smoking tobacco is associated with inferior outcomes regardless of surgical procedure.

A systematic review and meta-analysis of arthroscopic assisted techniques for thumb carpometacarpal joint osteoarthritis.

Arthroscopic management of thumb carpometacarpal (CMC) osteoarthrosis (OA) is an approach that has unclear results. We performed a systematic review encompassing three electronic databases up to May 2016 for studies describing arthroscopic-assisted techniques for thumb CMC OA. Meta-analyses of visual analogue scores (VAS) for pain, Disabilities of the Arm, Shoulder and Hand (DASH) scores, grip strength and pinch strength before and after arthroscopy were performed for ten included non-randomized cohort studies comprising 294 patients. Based on Hedges' g measure, we found a large effect on VAS and DASH scores, a small effect on grip strength and no effect on pinch strength. On average, VAS improved by 4.1 cm, DASH by 22 points and grip strength by 2.8 kg. Complications were reported in 4% of patients. The use of arthroscopic-assisted techniques for thumb CMC OA is still limited; however, it may be a reasonable option for patients with thumb CMC OA who do not respond to non-operative treatment.

Secondary Surgery following Initial Replantation/Revascularization or Completion Amputation in the Hand or Digits.

BACKGROUND: The authors studied the rate of secondary surgery following replantation/revascularization or completion amputation in patients with traumatic upper extremity injuries. The authors hypothesized that there are no factors associated with secondary surgery after initial treatment and that travel distance to the authors' hospital does not influence the number of secondary operations. METHODS: A multi-institutional retrospective study was performed including patients presenting from 2006 to 2014. The authors included 1254 patients and calculated the incidence of secondary surgery following initial operative management. The authors performed multivariable regression analysis to determine factors associated with secondary surgery and ordinal logistic regression tested the association of living at a further distance (>50 miles) and having zero, one, or multiple secondary operations. RESULTS: The rate of secondary surgery was 25 percent for all patients: 51 percent following replantation/revascularization and 22 percent following completion amputation. The authors observed a trend for lower rate of secondary surgery over time among patients who underwent completion amputation. The mean number of secondary operations was 1.2 after replantation/revascularization versus 0.45 operations after completion amputation. Avulsion and multiple-digit injuries were associated with higher odds and Hispanic race was associated with lower odds of secondary surgery. Patients living more than 50 miles from the hospital had a higher likelihood of undergoing one or multiple secondary operations. CONCLUSIONS: Twenty-five percent of patients with traumatic, dysvascular digital injuries underwent secondary surgery following initial revascularization or completion amputation. Patients undergoing initial revascularization or replantation were more than twice as likely to undergo secondary surgery compared with those undergoing completion amputation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.
