Development of a Patient Decision Aid for Distal Radius Fractures in Patients aged ≥65 years.

PURPOSE: The ideal management of distal radius fractures (DRFs) in patients aged 65 years and older is debated. Acknowledging the evidence that both nonsurgical and surgical treatment yield similar outcomes one year after injury, a patient decision aid (PDA) could facilitate patient engagement in treatment decision-making. The purpose of this study was to develop a PDA to guide patients in the treatment of DRFs in patients ≥65 years of age. METHODS: The DRF PDA was developed using an established decision sciences framework. The PDA included an overview of DRFs, treatment options (casting vs surgery), risk/benefits, and a values clarification section. During the development phase, hand surgeons and patients reviewed the PDA; then, semistructured interviews were performed with participants to elicit feedback. RESULTS: Eleven patients and 11 hand surgeons participated in the study. All patients found the PDA useful and almost all stated it would make the treatment decision easier. Most patients believed that there was enough information in the PDA, but one desired more information about surgical risks. Almost all surgeons stated the PDA would be easy for patients to use and understand, and approximately half believed that it would help patients make a more informed decision. Most surgeons expressed that the PDA would complement their usual approach to counseling patients, but some noted it would involve changes to their workflow. Most participants believed the information presented was unbiased, but one patient thought it was biased toward surgery, whereas a few surgeons believed that it was biased toward nonsurgical treatment. CONCLUSIONS: All patients expressed that the PDA was informative, comprehensive, and easy to understand and would be helpful if they were deciding about DRF treatment. Surgeons believed that patients would find the PDA easy to use and understand, but some had concerns about incorporating it into their clinic workflow. CLINICAL RELEVANCE: A decision aid for the treatment of DRFs in patients aged ≥65 years can be used to engage patients in the shared decision-making process.

Caregiver Versus Surgeon Concerns in New Diagnosis of Congenital Hand and Upper Extremity Anomalies.

PURPOSE: The initial office visit can be a stressful time for families with children with congenital upper extremity differences. These families may have concerns that differ from the information that pediatric hand surgeons believe is important to discuss. The purpose of this study was to compare topics that families and surgeons believe are most important to address at the initial office visits to better inform and guide that visit. METHODS: Qualitative interviews were conducted with 15 pediatric hand surgeons and 17 caregivers of children with congenital upper extremity differences. Interviews were conducted using semi-structured guides. Interviews were recorded, transcribed, and analyzed using thematic analysis to identify recurring themes from both study groups. RESULTS: Overarching themes were similar between the groups and included diagnosis/cause, treatment, psychosocial considerations, future outcomes, and further resources. However, emphasis among these themes differed, with surgeons emphasizing the cause and events leading up to the diagnosis and caregivers preferring to discuss next steps and treatment options. Surgeons also discussed feelings of grief or guilt more commonly than the caregivers. CONCLUSIONS: Although surgeons emphasize the cause and psychosocial impact of a newly diagnosed congenital upper extremity difference at the initial office visit, caregivers mostly focused on the future and next steps that can be taken. CLINICAL RELEVANCE: Surgeons should ensure to address these issues so that families are comfortable with the treating surgeon and believe that their concerns are being adequately addressed.

Small residual fracture gaps delay time to union in length stable femur fractures treated with intrameduallary fixation.

OBJECTIVES: The purpose of this study was to investigate whether residual fracture gapping and translation at time of intramedullary nail (IMN) fixation for diaphyseal femur fractures were associated with delayed healing or nonunion. DESIGN: Retrospective cohort study SETTING: Level 1 trauma hospital, quaternary referral center PATIENTS/PARTICIPANTS/INTERVENTION: Length stable Winquist type 1 and 2 diaphyseal femur fractures treated with IMN at a single Level I trauma center were retrospectively reviewed. MAIN OUTCOME MEASURE: The largest fracture gap and translation were evaluated on immediate anteroposterior (AP) and lateral postoperative radiographs. Radiographic healing was assessed using Radiographic Union Score in Femur (RUSF) scores at each follow-up. Radiographic union was defined as a RUSF score ≥8 and consolidation of at least 3 cortices. ANOVA and student's t-tests were used to evaluate the influence of fracture gap parameters on time to union (TTU) and nonunion rate. Patients were stratified to measured average gap and translation distances <1mm, 1-3mm and >3mm for portions of the analysis. RESULTS: Sixty-six patients who underwent IMN with adequate follow-up were identified. A total of 93.9% of patients achieved union at an average of 2.8 months. Fractures with average AP/lateral gaps of <1mm, 1-2.9 mm, and >3mm had an average TTU of 70.1, 91.7, and 111.9 days respectively; fractures with larger residual gap sizes had a significantly longer TTU (p=0.009). Fractures with an average gap of 1-2.9mm and >3 mm had a significantly higher nonunion rate (1.5% and 4.5% respectively) compared to 0% nonunion in the <1 mm group (p=0.003). CONCLUSION: Residual gapping following intramedullary fixation of length stable diaphyseal femur fractures is associated with a significant increase in likelihood of nonunion. SUMMARY: Residual displacement of length stable femoral shaft fractures following intramedullary nailing can have a significantly negative impact on fracture healing. An average 3 mm AP/lateral residual fracture gap or a total of 6 mm of the AP + lateral fracture gap appeared to be a critical gap size with increased rates of nonunion and time to union. Therefore, we suggest minimizing the sum of the residual AP and lateral fracture gap to less than a total of 6 mm.

Hook of Hamate Fractures.

Hook of hamate fractures are uncommon injuries with unclear prevalence. Classic presenting symptoms include volar-ulnar hand/wrist pain and weakness in grip, with possible ulnar nerve paresthesias. Patient factors, such as activity level and desired return to work/sport, shape the most appropriate treatment regimen although excision of the hook has been adopted by most surgeons. Overall, once patients receive the correct diagnosis and are treated, good outcomes with high satisfaction rates are expected.

Indirect Cost of Traumatic Brachial Plexus Injuries in the United States.

BACKGROUND: Traumatic brachial plexus injuries (BPIs) disproportionately affect young, able-bodied individuals. Beyond direct costs associated with medical treatment, there are far-reaching indirect costs related to disability and lost productivity. Our objective was to estimate per-patient indirect cost associated with BPI. METHODS: We estimated indirect costs as the sum of (1) short-term wage loss, (2) long-term wage loss, and (3) disability payments. Short-term (6-month) wage loss was the product of missed work days and the average earnings per day. The probability of return to work was derived from a systematic review of the literature, and long-term wage loss and disability payments were estimated. Monte Carlo simulation was used to perform a sensitivity analysis of long-term wage loss by varying age, sex, and return to work simultaneously. Disability benefits were estimated from U.S. Social Security Administration data. All cost estimates are in 2018 U.S. dollars. RESULTS: A systematic review of the literature demonstrated that the patients with BPI had a mean age of 26.4 years, 90.5% were male, and manual labor was the most represented occupation. On the basis on these demographics, our base case was a 26-year-old American man working as a manual laborer prior to BPI, with an annual wage of $36,590. Monte Carlo simulation estimated a short-term wage loss of $22,740, a long-term wage loss of $737,551, and disability benefits of $353,671. The mean total indirect cost of traumatic BPI in the Monte Carlo simulations was $1,113,962 per patient over the post-injury lifetime (median: $801,723, interquartile range: $22,740 to $2,350,979). If the probability of the patient returning to work at a different, lower-paying job was doubled, the per-patient total indirect cost was $867,987. CONCLUSIONS: BPI can have a far-reaching economic impact on both individuals and society. If surgical reconstruction enables patients with a BPI to return to work, the indirect cost of this injury decreases. LEVEL OF EVIDENCE: Economic Level IV.

Amputee locomotion: determining the inertial properties of running-specific prostheses.

OBJECTIVES: (1) To test the validity of a trifilar pendulum in estimating moments of inertia (MOIs) for running-specific prostheses (RSPs), (2) to measure inertial properties (mass, center of mass [CM] position, and MOIs) for 4 RSPs, (3) to verify the influence of the stiffness on the inertial properties of RSPs, and (4) to develop a predictive equation to estimate RSP CM positions. DESIGN: An aluminum block with known MOIs was used for verifying the accuracy of the trifilar pendulum MOI measurements. MOI errors were investigated by systematically misaligning the block and pendulum principal axes across a range of 1 to 10cm. Mass, CM position, and MOI were tested across 4 RSP designs with 3 stiffness categories each. SETTING: University biomechanics laboratory. SPECIMENS: Four different RSP designs and 3 stiffness categories per design were examined. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: MOI errors from known values and principal axis misalignments between RSPs and pendulum; mass, CM positions, and RSP principal axis MOIs; and predictive equation CM position errors. RESULTS: The trifilar pendulum estimated MOIs within -6.21×10(-5)kg/m(2) (≤1% error) for a block with known MOIs. Misalignments of 1 to 5cm between the RSPs' and pendulum's CM yielded errors from .00002 to .00113 kg/m(2) (0.3%-59.2%). Each RSP's inertial properties are presented. MOIs about any axis varied <.004kg/m(2) across stiffness categories; MOIs differed up to .013kg/m(2) between different designs. The predictive CM equation erred between .010 and .028m when using average input values across an RSP design. CONCLUSIONS: Trifilar pendulums can accurately measure RSP MOI. The RSP inertial properties differed slightly across stiffness categories within each design, but differed more substantially across different RSP designs. Using a predictive equation to estimate RSP CM positions can provide adequate data, but directly measuring CM positions is preferable.
