A framework to make PROMs relevant to patients: qualitative study of communication preferences of PROMs.

PURPOSE: Patient-reported outcome measures are tools for evaluating symptoms, magnitude of limitations, baseline health status, and outcomes from the patient's perspective. Healthcare professional organizations and payers increasingly recommend PROMs for clinical care, but there lacks guidance regarding effective communication of PROMs with orthopedic surgery patients. This qualitative study aimed to identify (1) patient attitudes toward the use and communication of PROMs, and (2) what patients feel are the most relevant or important aspects of PROM results to discuss with their physicians. METHODS: Participants were recruited from a multispeciality orthopedic clinic. Three PROMs: the EuroQol-5 Dimension, the Patient-Specific Functional Scale, and the Patient-Reported Outcome Measurement Information System Physical Function Computer Adaptive Test were shown and a semi-structured interview was conducted to elicit PROMs attitudes and preferences. Interviews were transcribed and inductive-deductively coded. Coded excerpts were aggregated to (1) identify major themes and (2) analyze how themes interacted. RESULT: Three themes emerged: (1) Beliefs toward the purpose of PROMs, (2) PROMs as a reflection of self, and (3) PROMs to facilitate communication and guide healthcare decisions. These themes informed a framework outlining the patient perspective on communicating PROMs during clinical care. CONCLUSION: Patient attitudes toward the use and communication of PROMs start with the incorporation of patient beliefs, which can facilitate or act as a barrier to engagement. Patients should ideally believe that PROMs are an accurate reflection of personal health state before incorporation into care. Clinicians should endeavor to communicate the purpose of a chosen PROM in line with a patient's unique needs and what they feel is most relevant to their own care. Aspects of PROMs results which may be helpful to address include providing context for what scores mean and how they are calculated, and using scores as a way to weigh risks and benefits of treatment and tracking progress over time. Future research can focus on the effect of communication strategies on patient outcomes and engagement in care.

Multidisciplinary Extremity Preservation Program Improves Quality of Life for Patients with Advanced Limb Threat.

BACKGROUND: The need for multidisciplinary care of patients with advanced limb threat is well established. We examined patient reported outcomes and health-related quality of life (HR-QoL) for those who completed a multidisciplinary extremity preservation program (EPP) at our institution. METHODS: Patients with advanced limb threat, who had previously failed standard management at a tertiary-care center, were referred to EPP for evaluation by a multidisciplinary panel of vascular, plastic, orthopedic and podiatric surgeons, along with infectious disease, prosthetics, orthotics, imaging, palliative care, social work and wound nursing specialists. HR-QoL was quantified before and after EPP participation with the RAND-36 questionnaire. The validated RAND-36 assesses physical function, role limitations caused by physical and emotional health problems, social functioning, emotional well-being, energy, pain and general health perceptions. RESULTS: From 2018 to 2020, 185 patients were referred to EPP. After review by the multidisciplinary panel, 120 were accepted into the program, 63 of whom completed their course of care; 9 were one-time consultations. The median number of EPP in-person care visits was 23 (13-54) per participant; 87.3% of patients received one or more surgical procedure, including operative debridement (73%), revascularization (44%), soft-tissue reconstruction or transplantation (46%), as well as hyperbaric oxygen therapy (11%) during their course of treatment. 85.7% of patients achieved complete wound healing, 41.5% occurring within 6 months. Ultimately, 14.3% required a major amputation. Graduates noted improvement in all categories of the HR-QoL upon completion, including those undergoing major amputation. On adjusted multivariate regression analysis, patients with immunocompromised status were more likely to show greater improvement in their social function (OR: 10.1; P < 0.044) and emotional role limitation (OR: 8.1; P = 0.042), while, patients with larger wound volume at presentation were more likely to have greater improvement in their general health (OR: 1.1; P < 0.049). Conversely, patients with a smoking history had less improvement in energy level (OR: 0.4; P = 0.044) and patients with dialysis-dependence had less improvement in social function (OR: 0.2; P = 0.034). CONCLUSIONS: Coordinated, multidisciplinary extremity preservation program improves HR-QoL of patients with complex limb threat, including those who are immunocompromised with impaired social function and emotional role limitations. Furthermore, study is warranted to better characterize the generalizability of this approach, including considerations of cost-effectiveness, wound recidivism, and limiting the number of in-person visits required to achieve complete healing.

Short-term outcomes following dehydrated micronized allogenic cartilage versus isolated microfracture for treatment of medial talar osteochondral lesions.

BACKGROUND: Osteochondral lesions of the talus (OLTs) have been traditionally treated with bone marrow stimulation techniques such as microfracture. However, conventional microfracture results in a biomechanically weaker repair tissue of predominantly type I collagen. Acellular micronized cartilage matrix (MCM) serves as a bioactive scaffold to restore hyaline cartilage. The purpose was to compare short-term outcomes after microfracture with and without augmentation with MCM for medial-sided OLTs. METHODS: A retrospective review was performed between 2010-2019 for medial-sided OLTs undergoing treatment with either microfracture augmented with MCM or isolated microfracture. The MCM was hydrated with either bone marrow aspirate concentrate (BMAC) or platelet-rich plasma (PRP). Outcomes included visual analogue scale (VAS) pain scores, Foot and Ankle Activity Measure (FAAM) scores, return-to-daily activities, and return-to-sport. RESULTS: 48 patients (14 MCM with PRP, 6 MCM with BMAC; 28 isolated microfracture) with average age 35.5 years (range: 13.8-67.2 years) and mean follow-up 4.0 ± 3.4 years (range,.13-10.7) were included. There was no difference in average lesion size between MCM and microfracture groups (64.0 ± 49.4 mm2 versus 57.3 ± 44.2 mm2, P = .63) and a trend toward larger lesion size for BMAC compared to PRP (106.5 ± 59.2 versus 45.9 ± 32.1 mm2, P = .056). There was no difference in time to return-to-activity (83.5 ± 18.8 versus 87.3 ± 49.1 days) or return-to-sports (151.9 ± 62.2 versus 165 ± 99.2 days) with MCM versus isolated microfracture. However, the MCM group had a significantly greater improvement in VAS pain score at final follow-up (4.9 ± 2.2 versus 2.7 ± 2.6, P = .0032) and significantly higher post-operative FAAM-Activities of Daily Living subscale scores (97.2 ± 8.2 versus 79.7 ± 32.8, P = .033). CONCLUSIONS: Augmenting microfracture with MCM hydrated with PRP or BMAC may result in beneficial changes in pain scores and activities of daily living, but similar return-to-activities and return-to-sport times compared to microfracture alone in management of medial OLT. LEVEL OF EVIDENCE: IV.

Does a Question Prompt List Improve Perceived Involvement in Care in Orthopaedic Surgery Compared with the AskShareKnow Questions? A Pragmatic Randomized Controlled Trial.

BACKGROUND: Most conditions in orthopaedic surgery are preference-sensitive, where treatment choices are based on the patient's values and preferences. One set of tools increasingly used to help align treatment choices with patient preferences are question prompt lists (QPLs), which are comprehensive lists of potential questions that patients can ask their physicians during their encounters. Whether or not a comprehensive orthopaedic-specific question prompt list would increase patient-perceived involvement in care more effectively than might three generic questions (the AskShareKnow questions) remains unknown; learning the answer would be useful, since a three-question list is easier to use compared with the much lengthier QPLs. QUESTION/PURPOSE: Does an orthopaedic-specific question prompt list increase patient-perceived involvement in care compared with the three generic AskShareKnow questions? METHODS: We performed a pragmatic randomized controlled trial of all new patients visiting a multispecialty orthopaedic clinic. A pragmatic design was used to mimic normal clinical care that compared two clinically acceptable interventions. New patients with common orthopaedic conditions were enrolled between August 2019 and November 2019 and were randomized to receive either the intervention QPL handout (orthopaedic-specific QPL with 45 total questions, developed with similar content and length to prior QPLs used in hand surgery, oncology, and palliative care) or a control handout (the AskShareKnow model questions, which are: "What are my options? What are the benefits and harms of those options? How likely are each of those benefits and harms to happen to me?") before their visits. A total of 156 patients were enrolled, with 78 in each group. There were no demographic differences between the study and control groups in terms of key variables. After the visit, patients completed the Perceived Involvement in Care Scale (PICS), a validated instrument designed to evaluate patient-perceived involvement in their care, which served as the primary outcome measure. This instrument is scored from 0 to 13, with higher scores indicating higher perceived involvement. RESULTS: There was no difference in mean PICS scores between the intervention and control groups (QPL 8.3 ± 2.3, control 8.5 ± 2.3, mean difference 0.2 [95% CI -0.53 to 0.93 ]; p = 0.71. CONCLUSION: In patients undergoing orthopaedic surgery, a QPL does not increase patient-perceived involvement in care compared with providing patients the three AskShareKnow questions. Implementation of the three AskShareKnow questions can be a more efficient way to improve patient-perceived involvement in their care compared with a lengthy QPL. LEVEL OF EVIDENCE: Level II, therapeutic study.

Patient Perceptions Correlate Weakly With Observed Patient Involvement in Decision-making in Orthopaedic Surgery.

BACKGROUND: Shared decision-making between patients and physicians involves educating the patient, providing options, eliciting patient preferences, and reaching agreement on a decision. There are different ways to measure shared decision-making, including patient involvement, but there is no consensus on the best approach. In other fields, there have been varying relationships between patient-perceived involvement and observed patient involvement in shared decision-making. The relationship between observed and patient-perceived patient involvement in decision-making has not been studied in orthopaedic surgery. QUESTIONS/PURPOSES: (1) Does patient-perceived involvement correlate with observed measurements of patient involvement in decision-making in orthopaedic surgery? (2) Are patient demographics associated with perceived and observed measurements of patient involvement in decision-making? METHODS: We performed a prospective, observational study to compare observed and perceived patient involvement in new patient consultations for eight orthopaedic surgeons in subspecialties including hand/upper extremity, total joint arthroplasty, spine, sports, trauma, foot and ankle, and tumor. We enrolled 117 English-literate patients 18 years or older over an enrollment period of 2 months. A member of the research team assessed observed patient involvement during a consultation with the Observing Patient Involvement in Decision-Making (OPTION) instrument (scaled 1-100 with higher scores representing greater involvement). After the consultation, we asked patients to complete a questionnaire with demographic information including age, sex, race, education, income, marital status, employment status, and injury type. Patients also completed the Perceived Involvement in Care Scale (PICS), which measures patient-perceived involvement (scaled 1-13 with higher scores representing greater involvement). Both instruments are validated in multiple studies in various specialties and the physicians were blinded to the instruments used. We assessed the correlation between observed and patient-perceived involvement as well as tested the association between patient demographics and patient involvement scores. RESULTS: There was weak correlation between observed involvement (OPTION) and patient-perceived involvement (PICS) (r = 0.37, p < 0.01) in decision-making (mean OPTION, 28.7, SD 7.7; mean PICS, 8.43, SD 2.3). We found a low degree of observed patient involvement despite a moderate to high degree of perceived involvement. No patient demographic factor had a significant association with patient involvement. CONCLUSIONS: Further work is needed to identify the best method for evaluating patient involvement in decision-making in the setting of discordance between observed and patient-perceived measurements. Knowing whether it is necessary for (1) actual observable patient involvement to occur; or (2) a patient to simply believe they are involved in their care can inform physicians on the best way to improve shared decision-making in their practice.

Health Considerations for Female Orthopaedic Surgeons.

The number of female orthopaedic surgeons is increasing. They face unique health concerns, which include cancer risk, pregnancy and fertility problems, musculoskeletal issues, and mental health disorders. In 2010, a survey study showed a 2.9-fold increased prevalence of breast cancer in female orthopaedic surgeons, compared with women in the general US population. A follow-up study 13 years later showed a 3.97-fold higher prevalence of breast cancer in female orthopaedic surgeons compared with matched women in the US general population. Surveys on fertility have also reported that orthopaedic surgery is one of three surgical subspecialty fields with the highest rates of fertility difficulty. In addition, the rate of pregnancy loss in female surgeons was twice the rate compared with that of the general population. There is an increased risk of preterm delivery in female orthopaedic surgeons. Awareness, education, and preventive measures may help reduce these issues and thereby promote the recruitment, retainment, and success of female surgeons in orthopaedic surgery.

Pain Self-Efficacy Can Improve During a Visit With an Orthopedic Surgeon.

BACKGROUND: Greater pain self-efficacy (PSE) is associated with reduced pain, fewer limitations, and increased quality of life after treatment for orthopedic conditions. The aims of this study were to (1) assess if PSE improves during a visit with an orthopedic surgeon and (2) identify modifiable visit factors that are associated with an increase in PSE. MATERIALS AND METHODS: We performed a prospective observational study of orthopedic clinic visits at a multispecialty clinic from February to May 2022. New patients who presented to one of six orthopedic surgeons were approached for the study. Patients who provided consent completed a pre-visit questionnaire including the Pain Self-Efficacy Questionnaire (PSEQ) and demographic questions. A trained research member recorded the five-item Observing Patient Involvement in Decision Making Instrument (OPTION-5) score, number of questions asked, and visit duration. Immediately after the visit, patients completed a post-visit questionnaire consisting of the PSEQ and Perceived Involvement in Care Scale (PICS). RESULTS: Of 132 patients enrolled, 61 (46%) had improved PSE after the orthopedic visit, with 38 (29%) having improvement above a clinically significant threshold. There were no significant differences between patients with increased PSE and those without increased PSE when comparing the PICS, OPTION-5, questions asked, or visit duration. CONCLUSION: Almost half of the patients had improvement in PSE during an orthopedic visit. The causal pathway to how to improve PSE and the durability of the improved PSE have implications in strategies to improve patient outcomes in orthopedic surgery, such as communication methods and shared decision-making. Future research can focus on studying different interventions that facilitate improving PSE. [Orthopedics. 2024;47(4):e197-e203.].

Health Numeracy Is Associated With a Patient's Ability to Interpret Patient-Reported Outcome Measures Data.

BACKGROUND: Patient-reported outcome measures (PROMs) were originally developed as research tools; however, there is increasing interest in using PROMs to inform clinical care. Prior work has shown the benefits of implementing PROMs at the point of care, but a patient's health numeracy (their ability to understand and work with numbers) may affect their ability to interpret PROM results. MATERIALS AND METHODS: We recruited patients presenting to an outpatient orthopedic clinic. Forty-nine patients completed a survey that included demographic information, the short-form General Health Numeracy Test, and accuracy questions about four PROM displays (bar graph, table, line graph, pictograph) that indicated the same PROM results. RESULTS: Patients with higher health numeracy answered all display accuracy questions correctly (P=.016). Patients who preferred using the table were more likely to answer display accuracy questions incorrectly (odds ratio, 0.013, P=.024). The two most frequently preferred PROM formats were bar graphs and tables, and most patients preferred to learn about their PROM function scores via a combination of displays and verbal discussions. CONCLUSION: Patient health numeracy is associated with the ability to correctly interpret visual displays of PROMs. Implementation of PROMs at point of care currently does not account for health numeracy. Efforts to account for health numeracy when using PROMs at point of care may improve the efficacy of using PROMs to improve outcomes in orthopedic surgery. [Orthopedics. 2024;47(5):e255-e260.].

Current Use of Patient-Reported Outcome Measures Ignores Functional Demand.

INTRODUCTION: Patient-reported outcome measures (PROMs) are used in orthopaedic surgery to measure aspects of musculoskeletal function that are important to patients, such as disability and pain. However, current assessments of function using PROMs do not necessarily consider a patient's functional demands in detail. A patient's functional demands could serve as a confounder to their perception of their functional ability. Hence, functional demands may need to be adjusted for when PROMs are used to measure musculoskeletal function. METHODS: We conducted a cross-sectional study in which new orthopaedic patients completed a questionnaire regarding demographics, function [Patient-Reported Outcomes Measurement Information System], functional demand (Tegner Activity Level Scale), pain self-efficacy, and symptoms of depression. 169 eligible patients with diverse orthopaedic conditions were enrolled in the study from an orthopaedic clinic, and 19 were excluded for incomplete questionnaires. RESULTS: The mean Patient-Reported Outcomes Measurement Information System score was 36.5 ± 9.1, and the mean Tegner score was 2.6 ± 2.0. In the multivariable regression model, patient-reported function was significantly associated with functional demand (ß = 0.17, P < 0.001). Significant associations were observed for pain self-efficacy (ß = 0.15, P < 0.001), acuity (ß = -0.10, P = 0.004), and age 80 years or older (ß = -0.16, P = 0.004). No notable association was observed with depression or age 65 to 79 years. DISCUSSION: Higher patient-reported physical function is associated with higher levels of functional demand when controlling for psychosocial factors, acuity, and age. Because of its confounding effect on measuring physical function, functional demand should be assessed and included in models using PROMs before and after surgery. For example, payment models using improvements in PROMs, such as the short form of the Hip dysfunction and Osteoarthritis Outcome Score and the Knee injury and Osteoarthritis Outcome Score after joint arthroplasty, should include functional demand in the model when assessing quality of care. LEVEL OF EVIDENCE: Level II.

The Environmental Impact of Orthopaedic Surgery.

➤: There are a growing number of opportunities within the field of orthopaedic surgery to address climate change and investigate ways to promote sustainability. ➤: Orthopaedic surgeons can take a proactive role in addressing climate change and its impacts within the areas of operating-room waste, carbon emissions from transportation and implant manufacturing, anesthetic gases, and water usage. ➤: Future studies are needed to further these initiatives on quantifying and decreasing environmental impact and furthering sustainable use of our resources.

Supercharged free fibula for complex ankle arthrodesis: a case report.

We report the successful use of a supercharged free fibula for tibial reconstruction and ankle arthrodesis. A 28-year-old woman underwent resection of a giant cell tumor of the distal tibia and reconstruction using a methyl methacrylate cement spacer 12 years prior. The spacer eroded into her ankle joint causing significant pain with ambulation. Therefore, she required ankle arthrodesis but lacked distal tibia bone stock. The ipsilateral fibula was harvested for reconstruction and transferred on its distal blood supply into the bony tibial defect. The proximal blood supply of the fibula flap was then anastomosed to the posterior tibial vessels to supercharge the blood supply. An Ilizarov was placed for external fixation. The combination of a supercharged free fibula and stable external fixation for tibial reconstruction led to timely bony union and ambulation, as well as avoiding the potential complications that can occur with other reconstructive options.

Current concepts review: intra-articular fractures of the calcaneus.

1) Intra-articular fractures of the calcaneus are associated with severe long-term consequences for function and pain. The condition of the soft tissues is of paramount importance when determining the method of treatment,the timing of surgery, and the post-injury rehabilitation.2) Intra-articular fractures are difficult to fully evaluate with plain radiographs. Computed tomography may assist in assessing the fracture pattern and planning for surgery. The likelihood of a good to excellent outcome is increased when an anatomic reduction is obtained.3) The outcome after operative management is difficult to characterize and appears to be influenced by factors related to the fracture, the patient, and the experience of the institution where the patient obtains treatment.All these factors should be factors in the decision to operate, but no single factor reliably determines the most appropriate treatment.4) Open reduction and internal fixation through an extensile approach achieves acceptable results in carefully selected patients. The use of a limited exposure with minimally invasive techniques may decrease the incidence of wound complications. However, this option is technically demanding and the quality of the reduction achieved may be more difficult to obtain and determine intraoperatively. Open fractures should be promptly debrided. The choice of fixation after reduction is based on the surgeons assessment of the soft tissue and the risk of infection.5) Post-traumatic arthritis of the subtalar joint is a common complication. Successful salvage can be achieved with a subtalar arthrodesis. However, these results may be influenced by the institution at which the initial management was rendered.

Locked versus nonlocked plate fixation for first metatarsophalangeal arthrodesis: a biomechanical investigation.

BACKGROUND: First metatarsophalangeal (MTP) arthrodesis using dorsal plate fixation is a common procedure for painful conditions of the great toe. Locked plates have become increasingly common for arthrodesis procedures in the foot, including the hallux MTP joint. The biomechanical advantages and disadvantages of these plates are currently unknown. The purpose of this study was to compare locked and nonlocked plates used for first MTP fusion for strength and stiffness. MATERIALS AND METHODS: The first ray of nine matched pairs of fresh-frozen cadaveric feet underwent dissection, preparation with cup-and-cone reamers, and fixation of the MTP joint with a compression screw and either a nonlocked or locked stainless steel dorsal plate. Each specimen was loaded in a cantilever fashion to 90 N at a rate of 3 Hz for a total of 250,000 cycles. The amount of plantar MTP gap was recorded using a calibrated extensometer. Load-to-failure testing was performed for all specimens that endured the entire cyclical loading. Stiffness was calculated from the final load-to-failure test. RESULTS: The locked plate group demonstrated significantly less plantar gapping during fatigue endurance testing from cycle 10,000 through 250,000 (p < .05). Mean stiffness was significantly greater in the locked plate group compared with the nonlocked plate group (p = .02). There was no significant difference in load to failure between the two groups (p = .27). CONCLUSION: Compared with nonlocked plates, locked hallux MTP arthrodesis plates exhibited significantly less plantar gapping after 10,000 cycles of fatigue endurance testing and significantly greater stiffness in load-to-failure testing. CLINICAL RELEVANCE: As the use of locked plate technology is becoming increasingly common for applications in the foot, a thorough understanding of the biomechanical characteristics of these implants may help optimize their indications and clinical use.

Health Literacy and Patient Participation in Shared Decision-Making in Orthopedic Surgery.

The influence of health literacy on involvement in decision-making in orthopedic surgery has not been analyzed and could inform processes to engage patients. The goal of this study was to determine the relationship between health literacy and the patient's preferred involvement in decision-making. We conducted a cross-sectional observational study of patients presenting to a multispecialty orthopedic clinic. Patients completed the Literacy in Musculoskeletal Problems (LiMP) survey to evaluate their health literacy and the Control Preferences Scale (CPS) survey to evaluate their preferred level of involvement in decision-making. Statistical analysis was performed with Pearson's correlation and multivariable logistic regression. Thirty-seven percent of patients had limited health literacy (LiMP score <6). Forty-eight percent of patients preferred to share decision-making with their physician equally (CPS score=3), whereas 38% preferred to have a more active role in decision-making (CPS score≤2). There was no statistically significant correlation between health literacy and patient preference for involvement in decision-making (r=0.130; P=.150). Among patients with orthopedic conditions, there is no significant relationship between health literacy and preferred involvement in decision-making. Results from studies in other specialties that suggest that limited health literacy is associated with a preference for less involvement in decision-making are not generalizable to orthopedic surgery. Efforts to engage patients to be informed and participatory in decision-making through the use of decision aids and preference elicitation tools should be directed toward variation in preference for involvement in decision-making, but not toward patient health literacy.

Increased Prevalence of Breast and All-cause Cancer in Female Orthopaedic Surgeons.

INTRODUCTION: Cancer is the second leading cause of death among women in the United States. Previous studies demonstrate a higher prevalence of cancer among female orthopaedic surgeons. This study aimed to provide an updated prevalence of breast and all-cause cancer among female orthopaedic surgeons using a larger and more current study population. METHODS: We distributed surveys to female orthopaedic surgeons in national orthopaedic specialty societies. Six hundred seventy-two survey responses were collected. We calculated standardized prevalence ratios (SPRs) and 95% confidence intervals (CIs) based on gender-specific, race-specific, and age-specific cancer prevalence statistics in the US population. We compared the distribution of breast cancer risk factors with that of women in the 2018 and 2009 California Health Interview Survey. RESULTS: Fifty-one of the 672 surveyed surgeons reported a diagnosis of invasive cancer. Twenty reported breast cancer with a prevalence higher among female orthopaedic surgeons compared with the US female population (SPR: 2.89, 95% CI: 2.16 to 3.81, P < 0.001). The breast cancer prevalence was also higher among orthopaedic surgeons compared with the US female population (SPR: 3.97, 95% CI: 2.43 to 6.14, P = 0.003). DISCUSSION: The increased prevalence of breast and all-cause cancer among a larger and more diverse cohort of female orthopaedic surgeons confirms previous studies and provides an update regarding a concerning public health issue within this specialty.

Influence of stretching and warm-up on Achilles tendon material properties.

BACKGROUND: Controversy exists on stretching and warm-up in injury prevention. We hypothesized that warm up has a greater effect on Achilles tendon biomechanics than static stretching. This study investigated static stretching and warm-up on Achilles tendon biomechanics in recreational athletes, in vivo. MATERIALS AND METHODS: Ten active, healthy subjects, 5 males, 5 females, With a mean age of 22.9 years with no previous Achilles tendon injuries were recruited. Typical stretching and warm-up routines were created. Testing was performed in a randomized cross-over design. A custom-built dynamometer was utilized to perform controlled isometric plantarflexion. A low profile ultrasound probe was utilized to visualize the musculotendinous junction of the medial gastrocnemius. An eight-camera motion capture system was used to capture ankle motion. Custom software calculated Achilles tendon biomechanics. RESULTS: Achilles tendon force production was consistent. No statistically significant differences were detected in stretch, stiffness, and strain between pre-, post-stretching, and post-warm-up interventions. CONCLUSION: Stretching or warm-up alone, and combined did not demonstrate statistically significant differences. Stretching and warm-up may have an equivalent effect on Achilles tendon biomechanics. Prolonged and more intense protocols may be required for changes to occur. CLINICAL RELEVANCE: Stretching and warm-up of the Achilles before exercise are commonly practiced. Investigating the effect of stretching and warm-up may shed light on potential injury prevention.

Methods for Reducing Intraoperative Breast Radiation Exposure of Orthopaedic Surgeons.

BACKGROUND: Standard lead aprons and vests do not adequately shield the most common breast cancer site, the upper outer quadrant (UOQ), from intraoperative radiation. The purpose of the present study was to determine if lead sleeves, wings, and/or axillary supplements decreased intraoperative radiation exposure of the UOQ of the breast. METHODS: An anthropomorphic torso phantom (simulating the female surgeon) was placed adjacent to a standard operating room table. Dosimeters were placed bilaterally over the UOQ of the breast. Scatter radiation dose equivalent rates (mrem/hr) were measured during continuous fluoroscopy of a pelvic phantom (simulating the patient). Five protection configurations (no lead; lead vest; and vest with sleeves, wings, and axillary supplements), 2 surgeon positions (facing the table and perpendicular to the table), and 2 C-arm positions (anteroposterior and cross-table lateral projection) were tested. The t test was utilized with a Bonferroni correction for multiple t tests. RESULTS: Lead sleeves and axillary supplements decreased intraoperative radiation exposure to the UOQ of the breast when compared with a well-fitted standard lead vest alone (p < 0.01) across all surgeon and C-arm positions. The addition of wings decreased radiation exposure to a lesser extent than sleeves or axillary supplements, and the difference when compared with the lead vest alone did not reach significance (p = 0.29). Breast radiation exposure in the C-arm cross-table lateral projection was highest across all testing. CONCLUSIONS: The UOQ of the breast is not adequately protected by standard lead vests alone or vests with the addition of wings. Axillary supplements and sleeves improved protection of the breast. CLINICAL RELEVANCE: Modifications of lead protective vests may improve intraoperative breast radiation protection.

Opioid use among patients with pain syndromes commonly seeking surgical consultation: A retrospective cohort.

BACKGROUND: Surgeons often see patients with pain to exclude organic pathology and consider surgical treatment. We examined factors associated with long-term opioid therapy among patients with foot/ankle, anorectal, and temporomandibular joint pain to aid clinical decision making. METHODS: Using the IBM MarketScan® Research Database, we conducted a retrospective cohort analysis of patients aged 18-64 with a clinical encounter for foot/ankle, anorectal, or temporomandibular joint pain (January 2007-September 2015). Multivariable logistic regression was used to estimate adjusted odds ratios for factors associated with long-term opioid therapy, including age, sex, geographic region, pain condition, psychiatric diagnoses, and surgical procedures in the previous year. RESULTS: The majority of the cohort of 1,500,392 patients were women (61%). Within the year prior to the first clinical encounter for a pain diagnosis, 14% had an encounter for a psychiatric diagnosis, and 11% had undergone a surgical procedure. Long-term opioid therapy was received by 2.7%. After multivariable adjustment, older age (age 50-64 vs. 18-29: aOR 4.47, 95% CI 4.24-4.72, p < 0.001), region (South vs. Northeast, aOR 1.76, 95% CI 1.70-1.81, p < 0.001), recent surgical procedure (aOR 1.83, 95% CI 1.78-1.87, p < 0.001), male sex (aOR 1.14, 95% CI 1.12-1.16, p < 0.001) and recent psychiatric diagnosis (aOR 2.49, 95% CI 2.43-2.54, p < 0.001) were independently associated with long-term opioid therapy. CONCLUSION: Among patients with foot/ankle, anorectal, or temporomandibular joint pain, the risk of long-term opioid therapy significantly increased with older age, recent psychiatric diagnoses and surgical history. Surgeons should be aware of these risk factors in order to make high quality clinical decisions in consultations with these patients.

Biomechanical comparison of blade plate and intramedullary nail fixation for tibiocalcaneal arthrodesis.

BACKGROUND: Tibiocalcaneal arthrodesis is an uncommon salvage procedure used for complex problems of the ankle and hindfoot. A biomechanical evaluation of the fixation constructs of this procedure has not been studied previously. The purpose of this study was to compare intramedullary nail to blade plate fixation in a deformity model in fatigue endurance testing and load to failure. MATERIALS AND METHODS: Nine matched pairs of fresh frozen cadaveric legs underwent talectomy followed by fixation with a blade plate and 6.5-mm fully threaded cancellous screw or an ankle arthrodesis intramedullary nail. The specimens were loaded to 270 N at a rate of 3 Hz for a total of 250,000 cycles, followed by loading to failure. RESULTS: Intramedullary nail fixation demonstrated greater mean stiffness throughout the fatigue endurance testing, from cycles 10 through 250,000 (blade plate versus intramedullary nail; cycle 10, 93 +/- 34 N/mm versus 117 +/- 40 N/mm (t = 2.33, p = 0.04); cycle 100, 89 +/- 34 N/mm versus 118 +/- 42 N/mm (t = 3.16, p = 0.01); cycle 1000, 86 +/- 32 N/mm versus 120 +/- 45 N/mm (t = 3.52, p = 0.01); cycle 10,000, 83 +/- 36 N/mm versus 128 +/- 50 N/mm (t = 3.80, p = 0.01); cycle 100,000, 82 +/- 34 N/mm versus 126 +/- 52 N/mm (t = 3.70, p = 0.01); cycle 250,000, 80 +/- 31 N/mm versus 125 +/- 49 N/mm (t = 4.2, p = 0.003). There was no statistically significant difference between the intramedullary nail and blade plate fixation in cycle one or in load to failure; cycle 10, blade plate 70 +/- 38 N/mm and intramedullary nail 67 +/- 20 N/mm (t = 0.60, p = 0.56); load to failure, blade plate 808 +/- 193 N, IMN 1074 +/- 290 N) (p = 0.15). CONCLUSION: Intramedullary nail fixation was biomechanically superior to blade plate and screw fixation in a tibiocalcaneal arthrodesis construct. CLINICAL RELEVANCE: The ankle arthrodesis intramedullary nail provides greater stiffness for fixation in tibiocalcaneal arthrodesis, which may improve healing.

Radiation Exposure and Case Characteristics in National Sample of Female Orthopaedic Trauma and Arthroplasty Surgeons.

Background: The risks of radiation exposure in orthopaedic surgery have become a topic of increasing interest in the setting of widespread fluoroscopy use and concern for an increased prevalence of breast cancer among female orthopaedic surgeons. The aim of this national study of 31 female orthopaedic surgeons was to achieve a deeper understanding of fluoroscopic use in the OR and its associated exposure to radiation, by comparing female orthopaedic trauma and arthroplasty surgeons. Methods: A total of 31 surgeons wore dosimeters for 10 operating days each to track cumulative radiation exposure. Surgeons were not asked to modify their practice in any way, with no requirement that the operating days had to be chosen with the knowledge that fluoroscopy would be used. Participants were also asked to fill out a form at the end of each day, detailing the number of cases that day, the number of hours spent in the OR, and the total amount of time using fluoroscopy. Results: Trauma surgeons received significantly higher radiation doses in the OR (p=0.01) and reported longer use of fluoroscopy (p<0.001). Trauma surgeons also spent more time per day in the OR and had more cases per day compared to arthroplasty surgeons, but this difference was not significant. Radiation dose penetrating through protective equipment remained minimal. Conclusion: Although the female trauma surgeons in the study operated longer and performed more procedures per day, the higher radiation exposure was best explained by the amount of time fluoroscopy is used in the OR. The fluoroscopic times in this study therefore may be a useful self-assessment tool for attending trauma and arthroplasty surgeons. Awareness of these differences will hopefully increase an individual surgeon's mindfulness toward the length of fluoroscopy use in each case, regardless of orthopaedic subspecialty.Level of Evidence: IV.
