Background Accurately distinguishing the severity of pathophysiology from the level of symptom intensity and incapability is a foundation of effective treatment strategies under the biopsychosocial paradigm of illness. With respect to idiopathic median neuropathy at the carpal tunnel (the symptoms and signs of which are referred to as carpal tunnel syndrome), surgeons who are more likely to recommend surgery based on the magnitude of symptoms and incapability rather than the severity of neuropathy may be underappreciating and undertreating mental health opportunities and overtreating mild, and on occasion unmeasurable, disease. A survey-based experiment that randomizes elements of the patient presentation can help determine the relative influence of magnitude of incapability on ratings of pathology severity. Question/purpose What factors are associated with severity rating of idiopathic median neuropathy at the carpal tunnel on an 11-point ordinal scale? Methods One hundred eight hand and wrist members of the Science of Variation Group (among approximately 200 participants who complete at least one survey-experiment a year related to the upper extremity on average) reviewed seven scenarios of fictional median neuropathy with seven randomized variables: age, gender, limitations of daily activity (incapability), Tinel and Phalen test results, duration of numbness episodes, prevention of numbness with nocturnal splint immobilization, constant numbness, and weakness of palmar abduction. Participants had a mean age of 51 ± 10 years, 90% (97 of 108) were men, and 74% (80 of 108) were subspecialized in hand surgery. Surgeons were asked to rate the severity of idiopathic median neuropathy at the carpal tunnel on a on an 11-point ordinal scale. Factors associated with rated severity were sought in multilevel ordered logistic regression models. Fifteen surgeons did not complete all of their assigned randomized scenarios, resulting in a total of 675 ratings. Results After controlling for potentially confounding variables such as magnitude of incapability, factors associated with severity rating on the 11-point ordinal scale included palmar abduction weakness (odds ratio 11 [95% confidence interval 7.7 to 15]), longer duration of symptom episodes (OR 4.5 [95% CI 3.3 to 6.2]), nocturnal numbness in spite of splint immobilization (OR 3.2 [95% CI 2.3 to 4.3]), constant numbness (OR 2.5 [95% CI 1.9 to 3.4]), positive Tinel and positive Phalen test results (OR 2.2 [95% CI 1.6 to 2.9]), and older age (OR 1.6 [95% CI 1.2 to 2.1]). Conclusion Our results suggest that surgeons rate the severity of idiopathic median neuropathy at the carpal tunnel based on evidence of worse pathophysiology and are not distracted by greater incapability. Clinical relevance Surgeons who consider greater incapability as an indication of more severe pathology seem to be practicing outside the norm and may be underappreciating and undertreating the unhelpful thoughts and feelings of worry or despair that consistently account for a notable amount of the variation in symptom intensity and magnitude of incapability.

Background Patients who help choose their health strategies are more adherent and achieve better health. An important role of the clinician is to verify that a patient’s expressed preferences are consistent with what matters most to the patient and not muddled by common misconceptions about symptoms or conditions. Patient choices are influenced by estimation of the potential benefits and potential harms of a given intervention. One method for quantifying these estimations is the concept of maximum acceptable risk (MAR), or the maximum risk that subjects are willing to accept in exchange for a given therapeutic benefit. This study addressed the hypothesis that misconceptions due to unhelpful cognitive bias regarding pain are associated with risk acceptance among people seeking care for an upper extremity condition. Methods We invited 140 new adult patients visiting an upper extremity specialist to complete a survey including demographics, pain intensity, depression and anxiety symptoms, catastrophic thinking, activity limitations, and MAR. Trauma or nontrauma diagnosis was obtained from the treating clinician and recorded by the research assistant. We used bivariate and linear regression analyses to identify factors associated with MAR among this population. Results Accounting for potential confounding in multivariable analysis, higher MAR was associated with older age and greater catastrophic thinking. Conclusions Specialists can be aware that people with more unhelpful cognitive biases may be willing to take more risk. Vigilance for common misconceptions and gentle, incremental reorientation of those misconceptions can increase the probability that people will choose options consistent with what matters most to them.

Background: The decision between radial head arthroplasty and open reduction internal fixation in the context of a terrible triad elbow fracture-dislocation is debated. This study investigated both surgeon and patient factors associated with surgeons’ recommendations to use arthroplasty. Methods: One hundred fifty-two surgeon members of the Science of Variation Group participated. Surgeons were asked to complete an online survey that included surgeon demographics and 16 patient scenarios. The patient scenarios were randomized using 2 patient variables and 2 anatomical variables. Multilevel logistic mixed regression analysis was performed to identify surgeon and patient variables associated with recommendations for radial head arthroplasty. Results: We found that radial head replacement was recommended in 38% of the scenarios. Scenarios with older patients, with fractures of the whole head, and those involving 3 fracture fragments were independently associated with radial head replacement. Conclusion: We found that most surgeons recommended radial head fracture fixation rather than arthroplasty. Surgeons were more likely to recommend fixation for younger patients with partial articular fractures or with fractures with 3 or fewer fracture fragments. It seems that surgeons are uneasy about using a prosthesis in a young active patient.

Background Experiments can determine if nerve-specific patient-reported outcome measures (PROMs) can outperform regional or condition-specific PROMs. We compared a nerve-specific PROM of the upper extremity, the Impact of Hand Nerve Disorders (I-HaND) scale, to other validated measures quantifying activity intolerance and sought to assess interquestionnaire correlations and factors independently associated with activity intolerance and pain intensity. Methods One hundred and thirty patients with any upper extremity nerve-related condition completed measures of demographics, psychological limitations, quality of life, activity intolerance, and pain intensity. To quantify activity intolerance, we used the I-HaND, Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity, and Disabilities of the Arm, Shoulder and Hand short form. Results Strong interquestionnaire correlations were found between the activity intolerance measures (r between 0.70 and 0.91). Multivariable analysis revealed that greater activity intolerance and greater pain intensity correlated most with greater symptoms of depression on all scales, with symptoms of depression accounting for 53 to 84% of the variability in the PROMs. Conclusion There is no clear advantage of the nerve-specific I-HaND over shorter, regional PROMs, perhaps because they are all so closely tied to mental health. Unless an advantage relating to responsiveness to treatment is demonstrated, we support using a brief arm-specific PROM for all upper extremity conditions. Level of Evidence Level II; Prognostic.

BACKGROUND Prior studies have suggested that misconceptions (i.e., unhelpful thoughts or cognitive errors resulting from cognitive bias) and distress (symptoms of anxiety or depression) are key factors associated with variation in health, as quantified with use of patient-reported outcome measures. The primary purpose of the present study was to identify mental-health phenotypes (i.e., combinations of various types of misconceptions and distress) that might help direct care and to test for differences in magnitude of activity tolerance, pain intensity, and self-efficacy in response to pain between phenotypes. We also studied demographic factors and diagnostic categories associated with mental-health phenotypes. METHODS In a cross-sectional study, 137 patients seeking upper-extremity musculoskeletal specialty care completed a survey including demographics, mental-health questionnaires, and measures of upper-extremity-specific activity tolerance, pain intensity, and pain self-efficacy. We used cluster analysis to identify groups of patients with similar phenotypes. We used analysis of variance testing to assess differences in activity tolerance, pain intensity, and pain self-efficacy among phenotypes. RESULTS The cluster analysis yielded 4 unique mental-health phenotypes, which fit the theoretical conceptualizations of "low misconception and low distress," "notable misconception," "notable depression and notable misconception," and "notable anxiety, depression, and misconception." Patients with low bias and low distress had significantly greater activity tolerance and greater pain self-efficacy than the other phenotypes, as well as a significantly lower pain intensity than phenotypes with notable distress. CONCLUSIONS Cluster analysis of mental-health questionnaire data can identify mental-health phenotypes that are associated with greater activity tolerance and pain intensity. This approach might help clinicians to strategize and prioritize approaches that correct unhelpful thoughts and ameliorate symptoms of distress among patients seeking musculoskeletal specialty care. Such strategies have the potential to achieve more comprehensive, whole-person care, more selective operative treatment, and improved outcomes. LEVEL OF EVIDENCE Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The evidence that symptom intensity and magnitude of limitations correlate with thoughts and emotions means that subjective signs, such as pain with physical examination, reflect both physical and mental health. During a 1-month evaluation of a rapidly healing upper extremity fracture with no risk of nonunion, 117 people completed measures of adaptiveness to pain and pain during the physical examination. Greater pain during examination correlated with less adaptive responses to pain and older age. This finding raises questions about using tenderness to assess fracture union. Level of evidence: II

Purpose We sought to compare overall satisfaction with treatment and satisfaction with initial wound healing after closure of office hand and upper extremity surgery wounds using polyamide compared to Chromic gut sutures. Methods We compared 62 patients randomized to polyamide suture closure of an office hand and upper extremity incision (mostly carpal tunnel release and trigger finger release) to 50 patients closed with Chromic gut suture. Patients rated overall treatment satisfaction, satisfaction with initial healing, pain intensity, and upper extremity–specific activity tolerance. Results Accounting for potential confounding in multivariable linear and logistic regression analysis, we found the following: (1) overall satisfaction with care was unrelated to suture type; (2) satisfaction with initial wound healing and appearance was lower among people with no other comorbidities, but unrelated to suture type; (3) there were no factors independently associated with pain intensity; and (4) excisional biopsy was associated with greater activity tolerance. Conclusions Our findings suggests that Chromic sutures are a viable alternative to polyamide sutures after office hand surgery, provided that the care team anticipates and develops strategies for concerns that may arise if the sutures take an extended period to fall off. Type of study/level of evidence Therapeutic II.

Background: The Tampa Scale for Kinesiophobia (TSK) is used to quantify fear of painful movement. A shorter form with only 4 questions (TSK-4) can be used by physicians to look for fear of movement independent of catastrophic thinking with less responder and survey burden. We assessed the difference explained in amount of variation in the Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity (PROMIS PF UE) between the TSK and TSK-4. Additionally, we looked for other factors that were associated with the PROMIS PF UE, and we assessed reliability and validity of the TSK and TSK-4 by looking at mean scaled scores, internal consistency, floor and ceiling effects, interquestionnaire correlations, and collinearity with the Pain Catastrophizing Scale short form (PCS-4), PROMIS Depression, and PROMIS Pain Interference (PROMIS PI). Methods: One hundred forty eight new and follow-up patients were seen at 5 orthopedic clinics in a large urban area and given the TSK, PROMIS PF UE, PROMIS Depression, PROMIS PI, and PCS-4 questionnaires. Results: Both long and short measures of greater fear of painful movement were independently associated with less physical function (PROMIS PF UE). The longer version accounted for more of the variation in physical function than the short version (TSK, semipartial R2 = 0.12, adjusted R2 full model 0.25; TSK-4, semipartial R2 = 0.03, adjusted R2 full model = 0.16, respectively). The shorter measure had slight floor and ceiling effects. There was high internal consistency for both the TSK and TSK-4. Conclusions: A short measure of fear of painful movement may be an adequate screen in the care of patients with upper extremity problems. Using this short form can help decrease questionnaire burden while accounting for kinesiophobia along with catastrophic thinking. Level of Evidence: Prognostic, level II

The pathophysiology of carpal adaptations after fracture of the distal radius is incompletely understood. We report 5 patients who had normal carpal alignment on injury radiographs that developed marked volar angulation of the lunate during recovery from volar plate fixation of a fracture of the distal radius. There were no signs of alteration of the carpal ligaments. Two patients had similar volar tilt on the contralateral side. The cause and optimal treatment of carpal malalignment after restoration distal radial alignment are unclear.

BACKGROUND: Intolerance of uncertainty—the tendency to overestimate the chance of and be unwilling to accept potential, but unlikely, negative outcomes in uncertain situations—is a cognitive construct that has been shown to affect symptoms and limitations for patients with traumatic and nontraumatic upper-extremity conditions. Cognitive flexibility and tolerance of uncertainty can be trained and practiced, with the potential to increase musculoskeletal health. However, to our knowledge, the degree to which intolerance of uncertainty might be associated with symptom intensity and the magnitude of limitations in adults with upper-extremity problems has not been characterized. QUESTIONS/PURPOSES: After accounting for personal and social factors, is intolerance of uncertainty independently associated with (1) the magnitude of physical limitations and (2) pain intensity? METHODS: In this cross-sectional, observational study, 139 new and returning patients presenting to one of four orthopaedic offices in a large urban area completed the Intolerance of Uncertainty Scale (a validated measure of the level of comfort with uncertain situations), the Patient-reported Outcomes Measurement Information System—Physical Function Upper Extremity computer adaptive test (to measure the magnitude of limitations), and an 11-point ordinal measure of pain intensity. The mean age of the 139 participants was 51 years ± 16 years and 55% (76 of 139) were men. Participants presented to the clinics with a wide variety of upper-extremity conditions, such as trigger finger, distal radius fractures, lateral epicondylitis, or non-specific shoulder pain. We also assessed sex, race, marital status, education level, income, public versus private insurance, area deprivation index, and the participant’s self-perception of their healthcare experience through a multiple-choice question (answer choices: none, some, a little, and a lot of experience). The following patient characteristics were more common in our study participants: white, employed, part of a married or unmarried couple, and private insurance coverage. We created two multivariable linear regression models to assess factors independently associated with the magnitude of limitations and pain intensity. RESULTS: After controlling for potentially confounding variables including sex, insurance, area deprivation index, and type of visit, we found that fewer physical limitations were associated with a greater intolerance of uncertainty (regression coefficient [β] -0.30; 95% confidence interval, -0.50 to -0.10; p = 0.003; semi-partial r(2) = 0.07; adjusted r(2) for the full model = 0.16), as was being a man (β 3.2; 95% CI, 0.08-6.3; p = 0.045; semi-partial r(2) = 0.03) and having private insurance coverage (β 5.2; 95% CI, 2.1-8.2; p = 0.001; semi-partial r(2) = 0.08). After controlling for one important potentially confounding variable, the level of education, greater pain intensity was associated with a greater intolerance of uncertainty (β 0.08; 95% CI, 0.02-0.14; p = 0.009; semi-partial r(2) = 0.05; adjusted r(2) for the full model = 0.08). CONCLUSIONS: Intolerance of uncertainty—a byproduct of cognitive bias and error, which are elements of the normal functioning of the human mind—increases limitations and pain intensity across diagnoses, independent of demographic and social factors. Future studies can address the effect of strategies that incorporate mindset training (for example, cognitive behavioral therapy and its derivatives) on musculoskeletal symptoms and limitations. LEVEL OF EVIDENCE: Level II, prognostic study.

Background: Despite studies demonstrating the effects of out-of-pocket costs on decision-making, the effect of societal cost information on patient decision-making is unknown. Given the considerable societal impact of cost of care for carpal tunnel syndrome (CTS), providing societal cost data to patients with CTS could affect decision-making and provide a strategy for reducing national health care costs. Therefore, we assessed the following hypotheses: (1) there is no difference in treatment choice (surgery vs no surgery) in a hypothetical case of mild CTS between patients randomized to receive societal cost information compared with those who did not receive this information; (2) there are no factors (eg, sex, experience with a previous diagnosis of CTS, or receiving societal cost information) independently associated with the choice for surgery; and (3) there is no difference in attitudes toward health care costs between patients choosing surgery and those who did not. Methods: In this randomized controlled trial using a hypothetical scenario, we prospectively enrolled 184 new and return patients with a nontraumatic upper extremity diagnosis. We recorded patient demographics, treatment choice in the hypothetical case of mild CTS, and their attitudes toward health care costs. Results: Treatment choice was not affected by receiving societal cost information. None of the demographic or illness factors assessed were independently associated with the choice for surgery. Patients declining surgery felt more strongly that doctors should consider their out-of-pocket costs when making recommendations. Conclusions: Providing societal cost information does not seem to affect decision-making and may not reduce the overall health care costs. For patients with CTS, health policy could nudge toward better resource utilization and finding the best care pathways for nonoperative and invasive treatments.

Background: An adaptive attitude toward aging might limit symptom intensity and magnitude of limitations. 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.

Background Perceived physician empathy is a strong driver of patient satisfaction. We assessed the influence of wait time, time spent with the surgeon, and surgeon stress level on the way patients rated surgeon empathy. Methods One hundred and fourteen patients visiting 1 of 6 participating surgeons were prospectively enrolled in the study. We recorded patient demographics and assessed the patient rating of perceived physician empathy. Time waiting for the surgeon and time spent with the surgeon were measured with use of ambulatory tracking systems and by research assistants with stopwatches outside the patient rooms. Patient ratings of surgeon empathy were assessed with use of the Jefferson Scale of Patient's Perceptions of Physician Empathy (JSPPPE), and surgeon stress level was assessed with use of the Perceived Stress Score short form. The mean wait time was 30 ± 18 minutes, and the mean time spent with the surgeon was 8.7 ± 5.3 minutes. Two separate multilevel linear regression models were used to compare factors associated with the JSPPPE and time spent with the surgeon. Results Neither time spent with the surgeon nor wait time was independently associated with perceived physician empathy; being male, having at least a post-college graduate degree, and higher self-reported surgeon stress levels were independently associated with less perceived empathy. More time spent with the surgeon was independently associated with lower self-reported surgeon stress levels; follow-up visits and visits for a traumatic condition were independently associated with less time spent with the surgeon. Conclusions The results of the present study show that improved communication strategies, rather than shorter wait time or increased time spent with the patient, may increase patient satisfaction. This should be a focus of future research.

Purpose Interventions that improve a patient’s understanding of the problem and their options might reduce surgeon-to-surgeon variation, activate healthier patient behaviors and mindset, and optimize stewardship of resources while improving quality of care. Patients with carpal tunnel syndrome (CTS) have more uncertainty about which course of action to take (so-called decision conflict) than hand surgeons. We studied patient preferences regarding shared decision making (SDM) for different parts of the treatment for CTS. We assessed the following hypotheses: (1) Younger age does not correlate with a preference for greater involvement in decisions; (2) Demographic and socioeconomic factors are not independently associated with (A) preferences for decision making (separated into preoperative, operative, postoperative, and the full SDM scale) and (B) the Control Preference Scale; (3) the SDM scale does not correlate with the Control Preference Scale. Methods We prospectively invited 113 new and postoperative patients with CTS to participate in the study. We recorded their demographics and they completed the SDM scale and the Control Preference Scale. Results The full SDM scale and all subsets showed a patient preference toward sharing the decisions for treatment with the surgeon with a moderate tendency toward patients wanting more surgeon involvement in decision making. On multivariable analysis, having commercial insurance compared with Medicare was independently associated with a preference for less surgeon involvement (ie, higher SDM scores) in decision making (regression coefficient, 0.60; 95% confidence interval, 0.03–1.2). Conclusions Patients with CTS generally prefer to share decisions with their surgeon with a tendency for more surgeon involvement especially in the operative and postoperative period. Clinical relevance Decision aids and preference elicitation tools used to ensure diagnostic and treatment decisions for CTS that are aligned with patient preferences are needed. Future studies might address the routine use of these tools on patient outcomes.

Purpose Decision aids (DAs) are tools designed to correct misconceptions, help people weigh the pros and cons of each option, and choose an option consistent with their values. This randomized controlled trial tested the difference in decision regret between patients who reviewed a DA at the end of the visit and those who did not. Secondary study questions addressed differences in pain self-efficacy, pain intensity, satisfaction, physical function, and treatment choice. Methods We enrolled 147 patients who visited an orthopedic upper-extremity surgeon for a condition that could be treated surgically or nonsurgically. We randomized 76 of these patients to review a DA as part of the visit (52%). At baseline, we measured results using the Pain Self-Efficacy short form, PROMIS Physical Function computer adaptive test, pain intensity on an 11-point ordinal scale, and satisfaction with the visit on an 11-point ordinal scale, as well as whether patients understood all received information and felt adequately educated to decide (no/yes), and choice of surgery, injection, or another treatment. Four to six weeks later, the survey by phone consisted of the PROMIS Physical Function computer adaptive test, pain intensity, satisfaction with the visit, the sense of a well-informed decision, and the Decision Regret Scale. We assessed factors independently associated with each measure. Results People who reviewed a DA had significantly less decision regret 4 to 6 weeks after the visit compared with those who did not. High pain self-efficacy was associated with lower likelihood to choose surgery during the initial visit, better physical function rates, and lower reported pain. Conclusions Decision aids reduce decision regret, which suggests that they help people organize their thoughts and make decisions more consistent with their values. Clinical relevance Hand surgeons can consider the use of DAs as a method for improving the quality of shared decisions.

Purpose The purpose of this study was to examine whether positively or negatively phrased Patient-Reported Outcome Measures (PROMs) prior to a visit with the hand surgeon affect patient perceived empathy and patient satisfaction (Patient-Reported Experience Measures [PREMs]). Methods Between June 2017 and July 2017, we enrolled 134 patients who presented to 3 hand surgeons at 2 outpatient offices. They were randomly assigned to 1 of 2 groups: completion of negatively framed questionnaires (Patient Health Questionnaire [PHQ-2], Pain Catastrophizing Scale [PCS-4], and Patient-Reported Outcomes Measurement Information System [PROMIS] depression Computer Adaptive Test [CAT]) or completion of positively framed questionnaires (Pain Self-Efficacy Questionnaire [PSEQ-2]) prior to the visit. At the end of the visit, all patients completed questionnaires on patient-perceived physician empathy and patient satisfaction. Five patients were excluded from the analysis after randomization. Results There was no statistically significant differences between groups on patient-perceived physician empathy and patient satisfaction. Conclusions Our findings suggest that the content of psychological questionnaires completed prior to the visit does not affect patient satisfaction and perceived empathy recorded after the visit. Clinical relevance Given the degree to which PROMs are influenced by psychosocial factors, and prior evidence that PROMs are primed by negatively framed questionnaires, it is reassuring that negatively framed PROMs did not affect PREMs, but more research is merited.

Objectives Anterior external fixation for pelvic ring fractures has shown to effectively improve stability and reduce mortality. However, these fixators can be associated with substantial morbidity such as pin tract infection, premature loss of fixation, and decreased quality of life in patients. Recently, two new methods of subcutaneous anterior pelvic internal fixation have been developed; the INFIX and the Pelvic Bridge. These methods have the purported advantages of lower wound complications, less surgical site pain, and improved quality of life. We sought to investigate the measured distances to critical anatomic structures, as well as the qualitative and topographic differences notable during implantation of both devices in the same cadaveric specimen. Materials and methods The Pelvic Bridge and INFIX were implanted in eleven fresh cadavers. Distances were then measured to: the superficial inguinal ring, round ligament, spermatic cord, lateral femoral cutaneous nerve (LFCN), femoral nerve, femoral artery, and femoral vein. Observations regarding implantation and topography were also recorded. Results The INFIX had greater measured distances from all structures except for the LFCN, in which its proximity placed this structure at risk. Neither device appears to put other critical structures at risk in the supine position. Significant implantation and topographic differences exist between the devices. The INFIX application lacked “safety margins” concerning the LFCN in 10/11 (90.9%) specimens, while Pelvic Bridge placement lacked “safety margins” with regard to the right superficial ring (1/11, 9%) and the right spermatic cord (1/11, 9%). Conclusions Both the Pelvic Bridge and INFIX lie at safe distances from most critical pelvic structures in the supine position, though INFIX application places the LFCN at risk.

Pyoderma gangrenosum (PG) is a rare inflammatory and ulcerative disorder of the skin. Despite the name, PG is not an infectious process. It is instead a neutrophilic dermatosis characterized by neutrophil-predominant cutaneous infiltrates. It is manifested clinically as an inflammatory papule or pustule that progresses to a painful ulcer with a well-defined erythematous to violaceous border and a purulent base. Nonspecific laboratory findings include leukocytosis, elevated erythrocyte sedimentation rate, and elevated C-reactive protein. Fever is often present in this disorder. A retrospective study looking at the medical records of patients with PG found that pathergy was documented in 31% of cases. The term pathergy refers to the induction or exacerbation of PG in sites of incidental or iatrogenic trauma. Because clinical and laboratory findings in PG are nonspecific, diagnosis depends on ruling out other disorders that are manifested with cutaneous ulcerations. After the exclusion of other disorders, the management of PG usually involves topical corticosteroids or immunosuppressants for mild, localized cases and systemic corticosteroids or cyclosporine for severe, extensive cases. Because of the phenomenon of pathergy, surgical procedures should generally be avoided in PG. We present a case of PG that was initially misdiagnosed as an infectious olecranon bursitis and treated as such, leading to clinical deterioration of the patient until the correct diagnosis was made. The purpose of this report is to make readers aware of the presentation of PG, of its overlapping features with

OBJECTIVES There are several metabolic factors known to be important for the maintenance of bone and muscle function. Causes of deficiency are multifactorial and can include such things as geographic region, latitude, and socioeconomic factors. The purpose of this study was to determine the prevalence of metabolic deficiencies. SETTING Level 1, urban trauma center. DESIGN Prospective laboratory evaluation. PATIENTS The subjects included 652 consecutive admits to the orthopaedic surgery service between July 1, 2011, and June 30, 2012. INTERVENTION Laboratory evaluation. MAIN OUTCOME MEASUREMENTS Metabolic and endocrine profiles included a serum analysis on all patients. Subject data included age, gender, body mass index, month of admission, and type of injury, and subjects' self-reported race, alcohol, recreational drug, and tobacco use were collected. RESULTS Six hundred fifty-two subjects with an average age of 41.2 years were evaluated. After data analysis, only 25-hydroxyvitamin D levels were found to be persistently poor across the patient population: 86.2% of subjects were insufficient in 25-hydroxyvitamin D (

First described in the early 1800s, heterotopic ossification (HO) refers to the formation of extraskeletal bone.1 In the upper extremity, HO most frequently occurs after injury to the elbow, and can result in severe functional impairment (Fig. 1). A variety of factors have been implicated, including elbow dislocation, open injury, severe chest injury, longer wait time to surgery, and prolonged immobilization.2,3 “Terrible triad” complex elbow fracture dislocations and distal humeral fractures have the highest rates of HO.3 A spectrum of HO formation exists after elbow injury, with more severe HO being associated with greater functional loss. Although associated injuries, radiographic findings, and clinical implications have been well documented, the molecular mechanisms have not pervaded the surgical literature. In the past several years, important advancements in our understanding of molecular mechanisms behind HO have been made. FIGURE 1 High-energy elbow injury resulting in ankylosed elbow joint secondary to HO. A injury. B Intraoperative reduction and stabilization. C Early HO.

Purpose Nonspecific upper extremity illnesses (eg,. wrist pain, forearm pain)—where no objectively verifiable pathology is detectable—are common and usually self-limiting. For some patients, a nonspecific diagnosis can contribute to mistrust and disappointment. Methods This study tested the primary null hypothesis that there is no difference in mean overall satisfaction between patients given a specific compared with a nonspecific diagnosis. Second, we assessed factors associated with satisfaction and with nonspecific upper extremity diagnosis. Results There was no significant difference between mean satisfaction with nonspecific and specific diagnoses in bivariate analysis. However, when treated as a categorical variable, 22% of the patients with a nonspecific diagnosis had a satisfaction score of 8 or lower compared with 11% of the patients given a specific diagnosis. First visit and greater pain intensity were significantly associated with a nonspecific diagnosis in bivariate analysis. In the multivariable models, no factors were independently associated with satisfaction or with nonspecific diagnoses. Conclusions Although nonspecific diagnoses can sometimes be frustrating for both physician and patient, in this small study using a satisfaction measure with a strong ceiling effect, they were no less satisfying to patients on average and corresponded with slightly greater pain intensity than specific diagnoses. Clinical relevance The degree to which nonspecific diagnoses (perhaps in combination with compassionate care and incremental monitoring) can be part of a satisfying treatment experience merits additional investigation.

Background Terrible triad complex elbow fracture-dislocations are represented by elbow dislocations associated with fractures of the coronoid and radial head. Published literature has focused on classifying coronoid fractures by their radiographic morphology on plain x-ray images and computed tomography imaging. No study has specifically related native coronoid osteology to in situ fracture morphology. We identified 3 distinct bony regions of the coronoid, (medial, intermediate, and lateral ridges) with correlation to common fracture patterns associated with terrible triad injuries. Methods Coronoid osteology in 8 fresh frozen cadaveric elbows was examined, and three distinct ridges were identified and dimensions measured. Results The measurements were compared with retrospective intraoperative measurements taken of coronoid fracture fragments being stabilized during terrible triad injury repair. Conclusion Classification of native coronoid process anatomy into functional ridges (medial, intermediate, lateral) may improve our understanding of coronoid fracture patterns in unstable terrible triad injuries.

The lateral collateral ligament (LCL) of the elbow is a complex capsuloligamentous structure critical in stabilizing the ulnohumeral and radiocapitellar articulations. LCL injury can result in elbow instability, allowing the proximal radius and ulna to externally rotate away from the humerus as a supination stress is applied to the forearm. Elbow dislocation is the most common cause of LCL injury, followed by iatrogenic injury. LCL pathology resulting in late recurrent instability is rare but disabling. The diagnosis requires a high index of suspicion, detailed history, and focused physical examination maneuvers. Stress radiographs are often the most useful imaging modality. Despite controversy over the anatomy of the LCL complex and the relative importance of its component structures, treatment of late instability is focused on lateral ligament reconstruction from the humerus to the ulna using tendon grafts with reasonably good outcomes.

Consistent with an aging population, the overall number of distal humeral fractures in the elderly is increasing. Indications for application of acute total elbow arthroplasty (TEA) in the setting of distal humeral fractures are still being defined. A variety of factors including chronologic age, physiologic age, bone quality, presence of pre-existing arthritis and pre-existing medical conditions need to be considered. Optimally the decision to proceed with TEA verses open reduction internal fixation (ORIF) is made preoperatively. The need to abandon ORIF may be not be apparent until after fracture exposure, and the presence of an olecranon osteotomy makes performing TEA challenging. A case is presented of acute conversion from ORIF to TEA following olecranon osteotomy, utilizing internal fixation bridging the ulnar component and its cement mantle.

Radial styloid fractures can occur in isolation or in association with other injuries, including complex intra-articular distal radius fractures, carpal fractures, carpal dislocations, and radiocarpal dislocations. The anatomy surrounding the radial styloid is complex, and complications related to surgical approach, treatments, and symptomatic hardware can occur. Operative treatments vary according to the injury pattern present, and pattern recognition is the key to optimizing treatment of these injuries. Outcomes are related to the precision of the reconstruction as well as the magnitude of the injury; better results are associated with lower-energy patterns.

The coronoid process has been shown to play a critical role in ulnohumeral stability. Coronoid process fractures can occur in isolation or as part of a complex injury pattern. The most common complex pattern, known as the "terrible triad," includes a radial head fracture and elbow dislocation along with the coronoid fracture. Failure to address these fractures and ligamentous injuries can result in recurrent instability and progression to painful arthrosis. Both medial and lateral approaches to the coronoid have been popularized in recent literature, but there is no universally accepted approach. Common fixation techniques include suture lasso, suture anchors, lag screws, and plating all of which have various drawbacks. We describe a direct anterior approach to address coronoid process fractures made in addition to a lateral approach to address radial head and lateral collateral ligament injuries. Coronoid fractures addressed through the anterior approach were stabilized with anterior to posterior screw fixation combined with buttress plating, which allowed anatomic reduction and stable internal fixation at short-term follow-up.

Renal cell carcinoma metastases to bone are classically considered radioresistant. We reviewed 28 patients who underwent irradiation for metastatic renal cell carcinomas to bone to test the hypothesis that irradiation of renal metastases to bone provides adequate palliation in carefully selected patients. Metastases were multifocal in all patients. All patients were followed until death. Overall, 36 index radiotherapy treatments were given as palliative initial treatment for 36 osseous metastatic sites. Twenty-five of 36 sites (69.5%) had no subsequent radiotherapy. Eight sites (22.2%) underwent repeat radiotherapy at a mean 28.9 weeks after treatment. Two (5.6%) additional sites underwent surgery at the site at an average 74 weeks later, and a pathologic fracture occurred at one (2.8%) site 3 weeks after irradiation. Overall, 33 of 36 (91.7%) sites had only radiotherapy as their source of palliation. Median times to return to pretreatment pain and functional levels, however, were 2 months and 1 month, respectively. Radiotherapy to osseous sites appears to control pain for the short term and generally prevents fractures and avoids the need for surgery in renal cell carcinoma patients with multiple bone metastases.

Case: A 67-year-old woman underwent internal fixation of an ankle fracture. Ten days postoperatively, the patient developed systemic hives, difficulty breathing, and oral swelling. At 8 weeks postoperatively, the hardware was removed because of a suspected metal hypersensitivity. Despite experiencing perioral edema and difficulty breathing after the hardware removal, she had complete resolution of the symptoms at the 2-week, 6-week, and 12-month follow-up appointments. Conclusion: Hypersensitivities to metal-based implants can develop and cause local and systemic reactions. Orthopaedic surgeons should inquire about a history of metal allergies, and possibly perform allergy testing for patients with a history suggestive of metal hypersensitivities. Consideration should be given for hospital admission following hardware removal for patient monitoring.

Purpose To determine the reliability of measuring ulnar variance on lateral wrist radiographs and to compare this technique with previously described methods. Methods Ulnar variance was measured in 100 normal wrist radiographs using the methods of perpendiculars, central reference point, and the lateral radiograph by 3 surgeons on 2 occasions. Intraobserver repeatability and agreement between raters and methods were assessed and compared. Results Intra- and interobserver reliability and agreement were both excellent using all 3 methods within a ± 1.0-mm cutoff. However, there was substantial pairwise disagreement in measures of ulnar variance between all 3 methods. Conclusions This study demonstrates that, for measurement of ulnar variance, the methods of perpendiculars, central reference point, and lateral radiographic measurement each have clinically acceptable intraobserver repeatability and interobserver agreement. Despite their independent reliability, each method of radiographic determination of ulnar variance had considerable disagreement with the other methods, indicative of inherent inaccuracies in the techniques. The lateral radiograph uniquely allows for visualization of the amount of ulnar head protruding proximal or distal to the concave lunate facet and allows for a rapid estimation of pronosupination, which is known to affect ulnar variance. Clinical relevance Determination of ulnar variance can be an important component of surgical decision making in various pathological conditions of the hand and wrist. Traditionally, it has been measured through methods using the posteroanterior wrist radiograph, but there are potential shortcomings with these methods, and use of the lateral radiograph may provide a more clinically relevant picture of ulnar variance. This study shows that measurement from the lateral radiograph provides similar reliability to previously accepted techniques.

STUDY DESIGN Diagnostic retrospective case series. OBJECTIVE To evaluate cervical intersegmental motion in rheumatoid arthritis patients using specialized tracking software (QMA) and compare the findings with a previously published cohort of "normal" subjects. SUMMARY OF BACKGROUND DATA Rheumatoid arthritis follows 3 patterns of cervical involvement, atlantoaxial subluxation, atlantoaxial impaction, and subaxial subluxation. Deformities present are sometimes considered "unstable" to the point where surgery can be recommended based on the interpretation of cervical radiographs. METHODS Cervical flexion-extension radiographs of 99 subjects with rheumatoid arthritis were evaluated. Angular and translational segmental motions were determined at each level using specialized tracking software. Findings were compared with previously published normative data using the same device. RESULTS Relative to controls, patients with rheumatoid arthritis demonstrated significantly less overall sagittal motion. Segmental analysis at C1-C2 demonstrated a 10% prevalence of dynamic motion outside the 95% confidence interval for "normal" patients. In contrast, segmental analysis at C2-C7 demonstrated no intersegmental motion outside the 95% confidence interval for "normal" subjects. CONCLUSIONS In patients with rheumatoid arthritis, abnormal motion at C1-C2 was consistent with truly dynamic deformity and should be closely evaluated. Conversely, subaxial subluxations, although frequently present, were relatively fixed deformities and in most cases, may not represent an unstable condition.

Purpose The elbow is an inherently stable joint because of its bony articulation and surrounding capsuloligamentous structures. Anatomic and biomechanical studies have focused on the medial and lateral collateral ligamentous contributions to stability. In 1918, Gray provided a qualitative description of the elbow capsule and its fibers. Our study was performed to detail the gross anatomy of the elbow capsule. Methods We evaluated the elbow capsule of 6 paired, fresh-frozen cadaveric specimens to detail gross capsular anatomy. Results We identified 3 distinct bands within the anterior capsule and 3 distinct bands within the posterior capsule. Conclusions Further study is needed to delineate the functional meaning of these anatomic findings. Clinical relevance Greater understanding of elbow capsule gross anatomy may lead to improved understanding of acute and chronic elbow pathoanatomy and treatment modalities.

Elbow arthrodesis (EA) is a procedure reserved for the salvage of failed elbow reconstruction or elbow injuries that defy reconstruction of a useful joint. Although arthrodesis of some joints is often straightforward and predictable, EA is technically difficult and associated with a high rate of complications. Furthermore, a successful EA does not translate to a gratifying clinical success. The functional limitations to activities of daily living and personal care are significant.
