RESUMEN
BACKGROUND: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture). METHODS: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications. RESULTS: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups. CONCLUSIONS: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

BACKGROUND: Clinical guidelines recommend low-molecular-weight heparin for thromboprophylaxis in patients with fractures, but trials of its effectiveness as compared with aspirin are lacking. METHODS: In this pragmatic, multicenter, randomized, noninferiority trial, we enrolled patients 18 years of age or older who had a fracture of an extremity (anywhere from hip to midfoot or shoulder to wrist) that had been treated operatively or who had any pelvic or acetabular fracture. Patients were randomly assigned to receive low-molecular-weight heparin (enoxaparin) at a dose of 30 mg twice daily or aspirin at a dose of 81 mg twice daily while they were in the hospital. After hospital discharge, the patients continued to receive thromboprophylaxis according to the clinical protocols of each hospital. The primary outcome was death from any cause at 90 days. Secondary outcomes were nonfatal pulmonary embolism, deep-vein thrombosis, and bleeding complications. RESULTS: A total of 12,211 patients were randomly assigned to receive aspirin (6101 patients) or low-molecular-weight heparin (6110 patients). Patients had a mean (±SD) age of 44.6±17.8 years, 0.7% had a history of venous thromboembolism, and 2.5% had a history of cancer. Patients received a mean of 8.8±10.6 in-hospital thromboprophylaxis doses and were prescribed a median 21-day supply of thromboprophylaxis at discharge. Death occurred in 47 patients (0.78%) in the aspirin group and in 45 patients (0.73%) in the low-molecular-weight-heparin group (difference, 0.05 percentage points; 96.2% confidence interval, -0.27 to 0.38; P<0.001 for a noninferiority margin of 0.75 percentage points). Deep-vein thrombosis occurred in 2.51% of patients in the aspirin group and 1.71% in the low-molecular-weight-heparin group (difference, 0.80 percentage points; 95% CI, 0.28 to 1.31). The incidence of pulmonary embolism (1.49% in each group), bleeding complications, and other serious adverse events were similar in the two groups. CONCLUSIONS: In patients with extremity fractures that had been treated operatively or with any pelvic or acetabular fracture, thromboprophylaxis with aspirin was noninferior to low-molecular-weight heparin in preventing death and was associated with low incidences of deep-vein thrombosis and pulmonary embolism and low 90-day mortality.

BACKGROUND: Limb-threatening lower extremity injuries often require secondary bone grafting after soft tissue reconstruction. We hypothesized that there would be fewer wound complications when performing secondary bone grafting via a remote surgical approach rather than direct flap elevation. METHODS: A retrospective cohort study was performed at a single Level 1 trauma center comparing complications after secondary bone grafting in patients who had undergone previous soft tissue reconstruction after open tibia fractures between 2006 and 2020. Comparing bone grafting via a remote surgical incision versus direct flap elevation, we evaluated wound dehiscence requiring return to the operating room as the primary outcome. Secondary outcomes were deep infection and delayed amputation. RESULTS: We identified 129 patients (mean age: 40 years, 82% male) with 159 secondary bone grafting procedures. Secondary bone grafting was performed via a remote surgical approach in 54% (n = 86) and direct flap elevation in 46% (n = 73) of cases. Wound dehiscence requiring return to the operating room occurred in one patient in the flap elevation group (1%) and none of the patients in the remote surgical approach. The odds of deep wound infection (OR, 1.77; p = 0.31) or amputation (OR, 1.43; p = 0.73) did not significantly differ between surgical approaches. No significant differences were found in complications between the reconstructive surgeon elevating and re-insetting the flap and the orthopaedic trauma surgeon performing the flap elevation and re-inset. CONCLUSION: Direct flap elevation for secondary bone grafting after soft tissue reconstruction for open tibia fractures did not result in more complications than bone grafting via a remote surgical approach. These findings should reassure surgeons to allow other clinical factors to influence the surgical approach for bone grafting.

OBJECTIVE: To determine what outcomes are most important to patients after a limb-threatening injury, and if those preferences vary based on the patients' treatment (salvage vs amputation), health, demographics, or time since injury. BACKGROUND: The preferences that motivate the patients' choice of treatment following a limb-threatening injury are poorly understood. Discrete choice experiments (DCEs) are a robust survey methodology to quantify preferences. METHODS: Patients with a history of traumatic limb-threatening injury, January 2010 to December 2020, completed a survey with our DCE and the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. The DCE attributes included recovery time, function, appearance, cost, and time in hospital. We used conditional logit modeling to estimate the relative importance of each attribute on a scale of 0% to 100%, determine willingness to pay for improvements in the included attributes, and assess variation in preferences based on patient characteristics, including PROMIS score. RESULTS: A total of 150 patients completed the survey (104 limb salvage, 46 amputation; mean age, 48±16 years; 79% male). Regaining preinjury function [relative importance=41%; 95% confidence interval (CI), 37%-45%] and minimizing costs (24%; 95% CI, 21%-28%) were of greatest importance. Changes in appearance were least important (7%; 95% CI, 5%-9%). The hierarchy of preferences did not vary between those who had limb salvage or amputation, but patient age, physical and mental health, and income were associated with preference variation. CONCLUSIONS: Patients with limb-threatening injuries most valued gains in function and reduced out-of-pocket costs.

OBJECTIVE: Widespread adoption of prehospital pelvic circumferential compression devices (PCCDs) by emergency medical services (EMS) systems has been slow and variable across the United States. We sought to determine the frequency of prehospital PCCD use by EMS providers. Secondarily, we hypothesized that prehospital PCCD use would improve early hemorrhagic shock outcomes. METHODS: We conducted a single-center retrospective cohort study of 162 unstable pelvic ring injuries transported directly to our center by EMS from 2011 to 2020. Included patients received a PCCD during their resuscitation (prehospital or emergency department). Prehospital treatment details were obtained from the EMS medical record. The primary outcome was the proportion of patients who received a PCCD by EMS before hospital arrival. Secondarily, we explored factors associated with receiving a prehospital PCCD, and its association with changes in vital signs, blood transfusion, and mortality. RESULTS: EMS providers documented suspicion of a pelvic ring fracture in 85 (52.8%) patients and 52 patients in the cohort (32.2%) received a prehospital PCCD. Wide variation in prehospital PCCD use was observed based on patient characteristics, geographic location, and EMS provider level. Helicopter flight paramedics applied a prehospital PCCD in 46% of the patients they transported (38/83); in contrast, the EMS organizations geographically closest to our hospital applied a PCCD in ≤5% of cases (2/47). Other predictors associated with receiving a prehospital PCCD included lower body mass index (p = 0.005), longer prehospital duration (p = 0.001) and lower Injury Severity Score (p < 0.05). We were unable to identify any improvements in clinical outcomes associated with prehospital PCCD, including early vital signs, number of blood transfusions within 24 hours, or mortality during admission (p > 0.05). CONCLUSION: Our results demonstrate wide practice variation in the application of prehospital PCCDs. Although disparate PCCD application across the state is likely explained by differences across EMS organizations and provider levels, our study was unable to identify any clinical benefits to the prehospital use of PCCDs. It is possible that the benefits of a prehospital PCCD can only be observed in the most displaced fracture patterns with the greatest early hemodynamic instability.

PURPOSE: Open reduction internal fixation of tibial plateau and pilon fractures may be complicated by deep surgical site infection requiring operative debridement and antibiotic therapy. The management of superficial surgical site infection is controversial. We sought to determine whether superficial infection is associated with an increased risk of deep infection requiring surgical debridement after fixation of tibial plateau and pilon fractures. METHODS: This is a secondary analysis of data from the VANCO trial, which included 980 adult patients with a tibial plateau or pilon fracture at elevated risk of infection who underwent open reduction internal fixation with plates and screws with or without intrawound vancomycin powder. An association of superficial surgical site infection with deep surgical site infection requiring debridement surgery and antibiotics was explored after matching on risk factors for deep surgical site infection. RESULTS: Of the 980 patients, we observed 30 superficial infections (3.1%) and 76 deep infections (7.8%). Among patients who developed a superficial infection, the unadjusted incidence of developing a deep infection within 90 days was 12.8% (95% confidence interval [CI] 1.3-24.2%). However, after a 3:1 match on infection risk factors, the 90-day marginal probability of a deep surgical site infection after sustaining a superficial infection was 6.0% (95% CI - 6.5-18.5%, p = 0.35). CONCLUSION: Deep infection after superficial infection is uncommon following operative fixation of tibial plateau and pilon fractures. Increased risk of subsequent deep infection attributable to superficial infection was inconclusive in these data. LEVEL OF EVIDENCE: Prognostic Level II.

Coronal plane hindfoot malalignment produces abnormal compensatory forces within the midfoot and forefoot. The primary aim of this study is to compare radiographic hindfoot alignment in patients with a midfoot Charcot event, and identify patterns associated with breakdown. A retrospective review of 43 patients (48 limbs) with midfoot Charcot neuroarthropathy were compared between the coronal hindfoot alignments and Charcot joint involvement. Coronal hindfoot alignment was classified as neutral (n = 15), valgus (n = 16), and varus (n = 17) utilizing the Saltzman hindfoot alignment radiograph. Charcot joint breakdown was classified as isolated tarsometatarsal joint (n = 8), combination of tarsometatarsal and naviculocuneiform joints (n = 22), and midtarsal joints including talonavicular and calcaneocuboid joints (n = 18). Patients exhibiting varus hindfoot alignment had 5.8 times greater risk of breakdown at the tarsometatarsal and naviculocuneiform joints (odds ratio 5.8, 95% confidence interval 1.7-22.9, p < .01). Hindfoot varus induces external rotation of the talus, resulting in compensation through the naviculocuneiform and tarsometatarsal joint, which correlates with our findings of a 6-fold increase in naviculocuneiform and tarsometatarsal joint collapse. Patients exhibiting valgus hindfoot alignment had 27 times greater risk of breakdown at the midtarsal joint (odds ratio 27.0; 95% confidence interval 5.6-207.0, p < .01). Hindfoot valgus induces internal rotation of the talonavicular joint, which correlates with our findings of a 27-fold increase in midtarsal joint breakdown. Varus and valgus hindfoot alignment are associated with different midfoot injury patterns, which may have implications in surgical management and allow for focused surveillance in neuropathic patients presenting with early-stage clinical findings consistent with Charcot neuroarthropathy.

Intramedullary screw fixation is a well-established surgical treatment for fifth metatarsal Jones fractures, due to its minimally invasive nature, and potential early return to activity. Due to the curvature of the fifth metatarsal, optimal length of the screw is needed to prevent gapping at the fracture site. The placement of a straight screw induces straightening of a naturally curved bone. The purpose of this study was to aid surgeons in determining an appropriate screw length for intramedullary fixation of a fifth metatarsal Jones fracture in order to prevent fracture gapping. A transverse osteotomy of the fifth metatarsal was made in 10 cadaver specimens at the level of a traditional Jones fracture. Inserted screws were sequentially increased in length until plantar gapping at the fracture site was noted. The angle (degree) of plantar gapping was measured with each increase in screw length and diameter. The mean length of the cadaveric fifth metatarsals was 73.76 mm (range 67.42-81.73). The mean screw length that caused gapping at the fracture site was 49.89 mm (range 44-55), representing 67.05% (range 61.26-75.35) of the fifth metatarsal length. The correlation coefficient revealed that gapping of the fracture site is most likely to occur when the screw length is 66% the length of the metatarsal length (rs = 0.66; 95% confidence interval: 0.06-0.91; p = .04). The angle of the initial gapping was 2.85° (range 2°-4°). With an incremental increase in screw length, the angle was 3.85° (range 3°-6°), and with an incremental increase in screw diameter, the angle was 3.70° (range 2°-5°). Our study demonstrated that screw lengths exceeding 66% of the metatarsal length lead to plantar fracture gapping. Additionally, gapping was accentuated with larger diameter screws due to angle variance.

The primary aim of the study was to evaluate the rate of tibial fracture with half pin placement in conjunction with tensioned wires in Ilizarov static external fixator in patients with peripheral neuropathy. Concentric visualization through a rancho cube and careful identification of anterior, posterior, medial, and lateral borders of the tibia, the "perfect circle" technique was used to ensure avoidance of cortical breach. Bivariate analysis was performed comparing the rates of tibia fractures in those who did and did not employ the "perfect circle" technique for placement of tibial half pins; evaluating for demographics, rationale for external fixation use, and postoperative amputation and complication rates. Tibial stress fractures, and early removal of pin/wires from external fixator secondary to breakage both occurred at statistically significant higher rates in patients in which the "perfect circle" technique was not employed (p < .001 and p = .03 respectively). The overall rate of tibia stress fractures was 2.08% (2/96), 0% (0/85) when "perfect circle" technique was used, compared to 18.18% (2/11) when it was not used. This study demonstrates a substantially low rate of tibia stress fractures with half pin use, in contrast to prior literature and should provide foot and ankle surgeons confidence, particularly when appropriate placement is observed in this high-risk population.

BACKGROUND: One of the biggest barriers to accessing safe surgical and anesthetic care is lack of trained providers. Uganda has one of the largest deficits in anesthesia providers in the world, and though they are increasing in number, they remain concentrated in the capital city. Salary is an oft-cited barrier to rural job choice, yet the size and sources of anesthesia provider incomes are unclear, and so the potential income loss from taking a rural job is unknown. Additionally, while salary augmentation is a common policy proposal to increase rural job uptake, the relative importance of non-monetary job factors in job choice is also unknown. METHODS: A survey on income sources and magnitude, and a Discrete Choice Experiment examining the relative importance of monetary and non-monetary factors in job choice, was administered to 37 and 47 physician anesthesiologists in Uganda, between May-June 2019. RESULTS: No providers worked only at government jobs. Providers earned most of their total income from a non-government job (50% of income, 23% of working hours), but worked more hours at their government job (36% of income, and 44% of working hours). Providers felt the most important job attributes were the quality of the facility and scope of practice they could provide, and the presence of a colleague (33% and 32% overall relative importance). These were more important than salary and living conditions (14% and 12% importance). CONCLUSIONS: No providers accepted the salary from a government job alone, which was always augmented by other work. However, few providers worked only nongovernment jobs. Non-monetary incentives are powerful influencers of job preference, and may be leveraged as policy options to attract providers. Salary continues to be an important driver of job choice, and jobs with fewer income generating opportunities (e.g. private work in rural areas) are likely to need salary augmentation to attract providers.

BACKGROUND: Value-based healthcare models aim to incentivize healthcare providers to offer interventions that address determinants of health. Understanding patient priorities for physical and socioeconomic recovery after injury can help determine which services and resources are most useful to patients. QUESTIONS/PURPOSES: (1) Do trauma patients consistently identify a specific aspect/domain of recovery as being most important at 6 weeks, 6 months, and 12 months after an injury? (2) Does the relative importance of those domains change within the first year after injury? (3) Are differences in priorities greater between patients than for a given patient over time? (4) Are different recovery priorities associated with identifiable biopsychosocial factors? METHODS: Between June 2018 and December 2018, 504 adult patients with fractures of the extremities or pelvis were surgically treated at the study site. For this prospective longitudinal study, we purposefully sampled patients from 6 of the 12 orthopaedic attendings' postoperative clinics. The participating surgeons surgically treated 243 adult patients with fractures of the extremities or pelvis. Five percent (11 of 243) of patients met inclusion criteria but missed their appointments during the 6-week recruitment window and could not be consented. We excluded 4% (9 of 243) of patients with a traumatic brain injury, 1% (2) of patients with a spinal cord injury, and 5% (12) of non-English-speaking patients (4% Spanish speaking [10]; 1% other languages [2]). Eighty-six percent of eligible patients (209 of 243) were approached for consent, and 5% (11 of 209) of those patients refused to participate. All remaining 198 patients consented and completed the baseline survey; 83% (164 of 198 patients) completed at least 6 months of follow-up, and 68% (134 of 198 patients) completed the 12-month assessment. The study participants' mean age was 44 ± 17 years, and 63% (125 of 198) were men. The primary outcome was the patient's recovery priorities, assessed at 6 weeks, 6 months, and 12 months after fracture using a discrete choice experiment. Discrete choice experiments are a well-established method for eliciting decisional preferences. In this technique, respondents are presented with a series of hypothetical scenarios, described by a set of plausible attributes or outcomes, and asked to select their preferred scenario. We used hierarchical Bayesian modeling to calculate individual-level estimates of the relative importance of physical recovery, work-related recovery, and disability benefits, based on the discrete choice experiment responses. The hierarchical Bayesian model improves upon more commonly used regression techniques by accounting for the observed response patterns of individual patients and the sequence of scenarios presented in the discrete choice experiment when calculating the model estimates. We computed the coefficient of variation for the three recovery domains and compared the between-patient versus within-patient differences using asymptotic tests. Separate prognostic models were fit for each of the study's three recovery domains to assess marginal changes in the importance of the recovery domain based on patient characteristics and factors that remained constant over the study (such as sex or preinjury work status) and patient characteristics and factors that varied over the study (including current work status or patient-reported health status). We previously published the 6-week results. This paper expands upon the prior publication to evaluate longitudinal changes in patient recovery priorities. RESULTS: Physical recovery was the respondents' main priority at all three timepoints, representing 60% ± 9% of their overall concern. Work-related recovery and access to disability benefits were of secondary importance and were associated with 27% ± 6% and 13% ± 7% of the patients' concern, respectively. The patients' concern for physical recovery was 6% (95% CrI 4% to 7%) higher at 12 months after fracture that at 6 weeks postfracture. The mean concern for work-related recovery increased by 7% (95% CrI 6% to 8%) from 6 weeks to 6 months after injury. The mean importance of disability benefits increased by 2% (95% CrI 1% to 4%) from 6 weeks to 6 months and remained 2% higher (95% CrI 0% to 3%) at 12 months after the injury. Differences in priorities were greater within a given patient over time than between patients as measured using the coefficient of variation (physical recovery [245% versus 7%; p < 0.001], work-related recovery [678% versus 12%; p < 0.001], and disability benefits [620% versus 33%; p < 0.001]. There was limited evidence that biopsychosocial factors were associated with variation in recovery priorities. Patients' concern for physical recovery was 2% higher for every 10-point increase in their Patient-reported Outcome Measure Information System (PROMIS) physical health status score (95% CrI 1% to 3%). A 10-point increase in the patient's PROMIS mental health status score was associated with a 1% increase in concern for work-related recovery (95% CrI 0% to 2%). CONCLUSION: Work-related recovery and accessing disability benefits were a secondary concern compared with physical recovery in the 12 months after injury for patients with fractures. However, the importance of work-related recovery was elevated after the subacute phase. Priorities were highly variable within a given patient in the year after injury compared with between-patient differences. Given this variation, orthopaedic surgeons should consider assessing and reassessing the socioeconomic well-being of their patients throughout their continuum of care. LEVEL OF EVIDENCE: Level II, therapeutic study.

BACKGROUND: Musculoskeletal injuries are common following trauma and variables that are associated with late femur fracture fixation are important to perioperative management. Furthermore, the association of late fracture fixation and multiple organ failure (MOF) is not well defined. METHODS: We performed a retrospective cohort investigation from 2 academic trauma centers. INCLUSION CRITERIA: age 18-89 years, injury severity score (ISS) >15, femoral shaft fracture requiring operative fixation, and admission to the intensive care unit >2 days. Admission physiology variables and abbreviated injury scale (AIS) scores were obtained. Lactate was collected as a marker of shock and was described as admission lactate (LacAdm) and as 24-hour time-weighted lactate (LacTW24h), which reflects an area under the curve and is considered a marker for the overall depth of shock. The primary aim was to evaluate clinical variables associated with late femur fracture fixation (defined as ≥24 hours after admission). A multivariable logistic regression model tested variables associated with late fixation and is reported by odds ratio (OR) with 95% confidence interval (CI). The secondary aim evaluated the association between late fixation and MOF, defined by the Denver MOF score. The summation of scores (on a scale from 0 to 3) from the cardiac, pulmonary, hepatic, and renal systems was calculated and MOF was confirmed if the total daily sum of the worst scores from each organ system was >3. We assessed the association between late fixation and MOF using a Cox proportional hazards model adjusted for confounding variables by inverse probability weighting (a propensity score method). A P value <.05 was considered statistically significant. RESULTS: One hundred sixty of 279 (57.3%) patients received early fixation and 119 of 279 (42.7%) received late fixation. LacTW24h (OR = 1.66 per 1 mmol/L increase, 95% CI, 1.24-2.21; P < .001) and ISS (OR = 1.07 per 1-point increase, 95% CI, 1.03-1.10; P < .001) were associated with higher odds of late fixation. Late fixation was associated with a 3-fold increase in the odds of MOF (hazard ratio [HR] = 3.21, 95% CI, 1.48-7.00; P < .01). CONCLUSIONS: In a cohort of multisystem trauma patients with femur fractures, greater injury severity and depth of shock, as measured by LacTW24h, were associated with late operative fixation. Late fixation was also associated with MOF. Strategies to reduce the burden of MOF in this population require further investigation.

BACKGROUND: This study aimed to address the current limitations of the use of composite endpoints in orthopaedic trauma research by quantifying the relative importance of clinical outcomes common to orthopaedic trauma patients and use those values to develop a patient-centered composite endpoint weighting technique. METHODS: A Best-Worst Scaling choice experiment was administered to 396 adult surgically-treated fracture patients. Respondents were presented with ten choice sets, each consisting of three out of ten plausible clinical outcomes. Hierarchical Bayesian modeling was used to determine the utilities associated with the outcomes. RESULTS: Death was the outcome of greatest importance (mean utility = - 8.91), followed by above knee amputation (- 7.66), below knee amputation (- 6.97), severe pain (- 5.90), deep surgical site infection (SSI) (- 5.69), bone healing complications (- 5.20), and moderate pain (- 4.59). Mild pain (- 3.30) and superficial SSI (- 3.29), on the other hand, were the outcomes of least importance to respondents. CONCLUSION: This study revealed that patients' relative importance towards clinical outcomes followed a logical gradient, with distinct and quantifiable preferences for each possible component outcome. These findings were incorporated into a novel composite endpoint weighting technique.

BACKGROUND: Given its role in treating musculoskeletal conditions, rehabilitation medicine may be an important factor in decreasing the use of opioids among injured workers. The primary objective was to determine if increased utilization of rehabilitation services was associated with decreased persistent opioid use among workers' compensation claimants. The secondary objective was to determine the combined association of rehabilitation service utilization and persistent opioid use with days of work lost due to injury. METHODS: Using Chesapeake Employers' Insurance Company claims data from 2008 to 2016, claimants with at least one filled opioid prescription within 90 days of injury were eligible for inclusion. The primary outcome was persistent opioid use, defined as at least one filled opioid prescription more than 90 days from injury. The secondary outcome was days lost due to injury. The primary variable of interest, rehabilitation service utilization, was quantified based on the number of rehabilitation service claims and grouped into five levels (no utilization, and four quartiles - low, medium, high, very high). RESULTS: Of the 9596 claimants included, 29% were persistent opioid users. Compared to claimants that did not utilize rehabilitation services, patients with very high rehabilitation utilization were nearly three times more likely (OR: 2.71, 95% CI: 2.28-3.23, p < 0.001) to be persistent opioid users and claimants with low and medium levels of rehabilitation utilization were less likely to be persistent opioid users (low OR: 0.20, 95%: 0.14-0.27, p < 0.001) (medium OR: 0.26, 95% CI: 0.21-0.32, p < 0.001). Compared to claimants that did not utilize rehabilitation services, very high rehabilitation utilization was associated with a 27% increase in days lost due to the injury (95% CI: 21.9-32.3, p < 0.001), while low (- 16.4, 95% CI: -21.3 - -11.5, p < 0.001) and medium (- 11.5, 95% CI: -21.6 - -13.8, p < 0.001) levels of rehabilitation utilization were associated with a decrease in days lost due to injury, adjusting for persistent opioid use. CONCLUSION: Our analysis of insurance claims data revealed that low to moderate levels of rehabilitation was associated with reduced persistent opioid use and days lost to injury. Very high rehabilitation utilization was associated with increased persistent opioid use and increased time from work.

BACKGROUND: Phalangeal neck fractures are commonly dorsally displaced and angulated. Surgical treatment is often necessary to restore the retrocondylar recess. The purpose of this study was to determine whether radiographic landmarks can serve as a reference tool for assessing phalangeal neck fracture alignment based on age and sex. METHODS: In total, 1061 lateral finger radiographs that were interpreted as "normal" by pediatric radiologists in children aged 1 to 18 years were retrospectively reviewed. The proximal and middle phalanges of each digit had a line drawn along the volar cortex [termed the volar phalangeal line (VPL)] and a second perpendicular line was drawn at the level of the phalangeal condyle. A ratio of the anterior to posterior aspects of the phalangeal condyle was determined at the intersection of these lines. Sex of the patients was noted to determine whether it influenced the temporal course of ossification. A linear regression model was utilized to determine the annual coefficient of growth for the phalangeal condyles. RESULTS: There is a temporal course of ossification of the proximal and middle phalangeal condyles. As children increase in age, the VPL will intersect the phalangeal condyle more dorsally due to the eccentric ossification. In children above 9 years of age, the VPL will reliably intersect the middle one third of the phalangeal condyle. No clinically significant difference exists between the ratios of the proximal and middle phalanges. Sex was not associated with a difference in growth. The greatest growth increase was observed in the 8 to 9-year-old interval. CONCLUSIONS: The phalangeal condyles ossify in an eccentric manner and the VPL will intersect the phalangeal condyle more dorsally with increasing age. The VPL and knowledge of where it should intersect the phalangeal condyle can be used as a reference guide for evaluating the reduction of proximal and middle phalangeal neck fractures in children. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Distal radius fractures are the most common injury in the pediatric population. The purpose of this study was to determine the variation among pediatric orthopaedic surgeons when diagnosing and treating distal radius fractures. METHODS: Nine pediatric orthopaedic surgeons reviewed 100 sets of wrist radiographs and were asked to describe the fracture, prescribe the type of treatment and length of immobilization, and determine the next follow-up visit. κ statistics were performed to assess the agreement with the chance agreement removed. RESULTS: Only fair agreement was present when diagnosing and classifying the distal radius fractures (κ=0.379). There was poor agreement regarding the type of treatment that would be recommended (κ=0.059). There was no agreement regarding the length of immobilization (κ=-0.004).Poor agreement was also present regarding when the first follow-up visit should occur (κ=0.088), whether or not new radiographs should be obtained at the first follow-up visit (κ=0.133), and if radiographs were necessary at the final follow-up visit (κ=0.163). Surgeons had fair agreement regarding stability of the fracture (κ=0.320).A subgroup analysis comparing various traits of the treatment immobilization showed providers only had a slight level of agreement on whether splint or cast immobilization should be used (κ=0.072). There was poor agreement regarding whether long-arm or short-arm immobilization should be prescribed (κ=-0.067).Twenty-three of the 100 radiographs were diagnosed as a torus/buckle fracture by all 9 surgeons. κ analysis performed on all the treatment and management questions showed that each query had poor agreement. CONCLUSIONS: The interobserver reliability of diagnosing pediatric distal radius fractures showed only fair agreement. This study demonstrates that there is no standardization regarding how to treat these fractures and the length of immobilization required for proper fracture healing. Better classification systems of distal radius fractures are needed that standardize the treatment of these injuries. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Medial epicondyle fractures are a common pediatric and adolescent injury accounting for 11% to 20% of elbow fractures in this population. This purpose of this study was to determine the variability among pediatric orthopaedic surgeons when treating pediatric medial epicondyle fractures. METHODS: A discrete choice experiment was conducted to determine which patient and injury attributes influence the management of medial epicondyle fractures by pediatric orthopaedic surgeons. A convenience sample of 13 pediatric orthopaedic surgeons reviewed 60 case vignettes of medial epicondyle fractures that included elbow radiographs and patient/injury characteristics. Displacement was incorporated into the study model as a fixed effect. Surgeons were queried if they would treat the injury with immobilization alone or open reduction and internal fixation (ORIF). Statistical analysis was performed using a mixed effect regression model. In addition, surgeons filled out a demographic questionnaire and a risk assessment to determine if these factors affected clinical decision-making. RESULTS: Elbow dislocation and fracture displacement were the only attributes that significantly influenced surgeons to perform surgery (P<0.05). The presence of an elbow dislocation had the largest impact on surgeons when choosing operative care (ß=-0.14; P=0.02). In addition, for every 1 mm increase in displacement, surgeons tended to favor ORIF by a factor of 0.09 (P<0.01). Sex, mechanism of injury, and sport participation did not influence decision-making. In total, 54% of the surgeons demonstrated a preference for ORIF for the included scenarios. On the basis of the personality Likert scale, participants were neither high-risk takers nor extremely risk adverse with an average-risk score of 2.24. Participant demographics did not influence decision-making. CONCLUSIONS: There is substantial variation among pediatric orthopaedic surgeons when treating medial epicondyle fractures. The decision to operate is significantly based on the degree of fracture displacement and if there is a concomitant elbow dislocation. There is no standardization regarding how to treat medial epicondyle fractures and better treatment algorithms are needed to provide better patient outcomes. LEVEL OF EVIDENCE: Level V.

Background and purpose - Most often, the goal of non-geriatric femoral neck fracture surgery is to preserve the native hip joint. However, reoperations for painful implants, osteonecrosis, and nonunion are common. We determined the reoperation rate and time-to-reoperation following internal fixation of these fractures in a large population cohort. Patients and methods - This retrospective cohort study included patients between the ages of 18 and 50 years old who underwent internal fixation for a femoral neck fracture during 1997-2013. Patients were followed until December 2013. Primary outcomes were reoperation rate and time-to-reoperation. Time-to-event analysis was performed to estimate the rate of any reoperation and for THA specifically, while testing the dependency of time-to-reoperation on secondary variables. Results - 796 young femoral neck fracture patients were treated with internal fixation during the study period (median age 43 years, 39% women). Median follow-up was 8 years (IQR 4-13). One-third underwent at least 1 reoperation at a median 16 months after the index surgery (IQR 8-31). Half of reoperations were for implant removal, followed by conversion to total hip arthroplasty. 14% of the cohort were converted to THA. The median time to conversion was 2 years (IQR 1-4). Neither female sex nor older age had a statistically significant effect on time-to-reoperation or time-to-THA conversion. Interpretation - Following internal fixation of young femoral neck fracture, 1 in 3 patients required a reoperation, and 1 in 7 were converted to THA. These data should be considered by patients and surgeons during treatment decision-making.
