An Integrated System Using Ultrasound-Based Registration for Surgical Navigation of Iliosacral Screw Insertions.

OBJECTIVE: Pelvic fractures often require fixation through iliosacral joint, typically guided by fluoroscopy using an untracked C-arm device. However, this involves ionizing radiation exposure and potentially inaccurate screw placement. We introduce the Navigated Orthopaedic Fixations using Ultrasound System (NOFUSS), a radiation-free ultrasound (US)-based end-to-end system for providing real-time navigation for iliosacral screw (ISS) insertions. METHODS: We performed surgeries on 8 human cadaver specimens, inserting four ISSs per specimen to directly compare NOFUSS against conventional fluoroscopy. Six specimens yielded usable (marginal or adequate quality) US images. RESULTS: The median screw entry error, midpoint error, and angulations errors for NOFUSS were 8.4 mm, 7.0 mm, and 1.4◦, compared to 7.5 mm (p = 0.52), 5.7 mm (p = 0.30), and 4.4◦ (p = 0.001) for fluoroscopy respectively. NOFUSS resulted in 6 (50%) breaches, compared to 2 (16.7%) in fluoroscopy (p = 0.19). The median insertion time was 7m 37s and 12m 36s per screw for NOFUSS and fluoroscopy respectively (p = 0.002). The median radiation exposure during the fluoroscopic procedure was 2m 44s, (range: 1m 44s - 3m 18s), with no radiation required for NOFUSS. When considering the three cadavers that yielded only adequate-quality US images (12 screws), the measured entry errors were 3.6 mm and 8.1 mm respectively for NOFUSS and fluoroscopy (p = 0.06). CONCLUSION: NOFUSS achieved insertion accuracies on par with the conventionalfluoroscopicmethod,andreducedinsertiontimesandradiation exposure significantly. SIGNIFICANCE: This study demonstrated the feasibility of an automated, radiation-free, US-based surgical navigation system for ISS insertions.

Trajectory of Recovery following ORIF for Distal Radius Fractures.

Background Distal radius fractures are commonly seen among the elderly, though studies examining their long-term outcomes are limited. Purpose The aim of this study was to describe the 5-year trajectory of recovery of distal radius fractures treated with open reduction and internal fixation (ORIF). Methods Patients with distal radius fractures (AO/OTA 23.A-C) treated by ORIF were prospectively studied. Patient-Rated Wrist Evaluation (PRWE) score was measured at baseline (preinjury recall) and postoperatively at 6 months, 1 year, and 5 years. Clinically relevant change in PRWE score was assessed using the minimal clinically important difference (MCID). Results A total of 390 patients were included, of which 75% completed 5-year follow-up. Mean baseline PRWE score was 1.25 (standard deviation, SD: 2.9). At 6 months, mean PRWE score was at its highest up to 20.2 (SD: 18.4; p < 0.01). A significant improvement in mean PRWE score was observed at 1 year down to 15.2 (SD: 17.6; p < 0.01); 44% of patients were still one MCID outside of their baseline PRWE score at 1 year. Further significant improvement in mean PRWE score occurred at 5 years down to 9.4 (SD: 13.4; p < 0.01); 29% of patients remained one MCID outside of their baseline PRWE score at 5 years. Conclusion Recovery after ORIF for distal radius fractures showed significant worsening after surgery, followed by significant improvements up to 1 year and between years 1 and 5, albeit to a lesser extent. Statistically and clinically relevant wrist pain and disability persisted at 5 years. Future research should examine different treatment modalities and include a nonoperative treatment arm for comparison. Level of Evidence Prognostic level II.

Applications of Natural Language Processing for Automated Clinical Data Analysis in Orthopaedics.

Natural language processing is an exciting and emerging field in health care that can transform the field of orthopaedics. It can aid in the process of automated clinical data analysis, changing the way we extract data for various purposes including research and registry formation, diagnosis, and medical billing. This scoping review will look at the various applications of NLP in orthopaedics. Specific examples of NLP applications include identification of essential data elements from surgical and imaging reports, patient feedback analysis, and use of AI conversational agents for patient engagement. We will demonstrate how NLP has proven itself to be a powerful and valuable tool. Despite these potential advantages, there are drawbacks we must consider. Concerns with data quality, bias, privacy, and accessibility may stand as barriers in the way of widespread implementation of NLP technology. As natural language processing technology continues to develop, it has the potential to revolutionize orthopaedic research and clinical practices and enhance patient outcomes.

The double-edged scalpel: Experiences and perceptions of pregnancy and parenthood during Canadian surgical residency training.

INTRODUCTION: Only 34% of Canadian surgeons in 2022 were female. The protracted length of surgical residency training, concerns regarding infertility, and increased rates of obstetrical complications have been shown to contribute to the disproportionate lack of females in surgical specialties. METHODS: A novel online survey was sent to all surgical residents in Canada. Respondents were asked about perceptions of pregnancy and parenthood during surgical training, and parents were asked about parental leave, accommodations they received, and pregnancy complications. Chi squared tests were used to compare opinions of male and female residents. RESULTS: A total of 272/2,419 (11.2%) responses were obtained, with a high response from females (61.8%) and orthopaedic residents (29.0%). There were 56 women reporting 76 pregnancy events during training, 62.5% of which had complications. Notably, 27.3% of men and 86.7% of women 'agreed' or 'strongly agreed' that surgeons have higher pregnancy complication rates than the general population (p<0.001). Men were much less likely to believe that pregnant residents should be offered modified duties (74.2% of men, 90.0% of women, p = 0.003). Women were much more likely to experience significant stigma or bias due to their status as a parent (43% of women, 0% of men, p<0.001). Women reported negative comments from others at a higher rate (58.5% of women, 40.7% of men, p = 0.013). Women believe there is negative stigma attached to being pregnant during training (62.7% of women, 42.7% of men, p = 0.01). The limitations of our study include a small sample size and response bias. CONCLUSION: Challenges and negative perceptions exist around pregnancy and parenthood in surgical residency, which disproportionately affect women trainees.

Radiographic Union Assessment in Surgically Treated Distal Femur Fractures: A Systematic Review.

BACKGROUND: Distal femur fractures are known to have challenging nonunion rates. Despite various available treatment methods aimed to improve union, optimal interventions are yet to be determined. Importantly, there remains no standard agreement on what defines radiographic union. Although various proposed criteria of defining radiographic union exist in the literature, there is no clear consensus on which criteria provide the most precise measurement. The use of inconsistent measures of fracture healing between studies can be problematic and limits their generalizability. Therefore, this systematic review aims to identify how fracture union is defined based on radiographic parameters for surgically treated distal femur fractures in current literature. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, Medline, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection databases were searched from inception to October 2022. Studies that addressed surgically treated distal femur fractures with reported radiographic union assessment were included. Outcomes extracted included radiographic definition of union; any testing of validity, reliability, or responsiveness; reported union rate; reported time to fracture union; and any functional outcomes correlated with radiographic union. RESULTS: Sixty articles with 3,050 operatively treated distal femur fractures were included. Operative interventions included lateral locked plate (42 studies), intramedullary nail (15 studies), dynamic condylar screw or blade plate (7 studies), dual plate or plate and nail construct (5 studies), distal anterior-posterior/posterior-anterior screws (1 study), and external fixation with a circular frame (1 study). The range of mean follow-up time reported was 4.3 to 44 months. The most common definitions of fracture union included "bridging or callus formation across 3 of 4 cortices" in 26 (43%) studies, "bony bridging of cortices" in 21 (35%) studies, and "complete bridging of cortices" in 9 (15%) studies. Two studies included additional assessment of radiographic union using the Radiographic Union Scale in Tibial fracture (RUST) or modified Radiographic Union Scale in Tibial fracture (mRUST) scores. One study included description of validity, and the other study included reliability testing. The reported mean union rate of distal femur fractures was 89% (range 58%-100%). The mean time to fracture union was documented in 49 studies and found to be 18 weeks (range 12-36 weeks) in 2,441 cases. No studies reported correlations between functional outcomes and radiographic parameters. CONCLUSION: The current literature evaluating surgically treated distal femur fractures lacks consistent definition of radiographic fracture union, and the appropriate time point to make this judgement is unclear. To advance surgical optimization, it is necessary that future research uses validated, reliable, and continuous measures of radiographic bone healing and correlation with functional outcomes.

Evaluation of the trajectory of recovery following surgically treated acetabular fractures.

Aims: Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years. Methods: Eligible patients at a level I trauma centre were recruited into a longitudinal registry of surgical acetabular fractures between June 2004 and August 2019. Patient-reported outcome measures (PROMs), including the 36-Item Short Form Health Survey (SF-36) physical component summary (PCS), were recorded at baseline pre-injury recall and six months, one year, two years, and five years postoperatively. Comparative analyses were performed for elementary and associated fracture patterns. The proportion of patients achieving minimal clinically important difference (MCID) was determined. The rate of, and time to, conversion to total hip arthroplasty (THA) was also established. Results: We recruited 251 patients (253 fractures), with a 4:1 male to female ratio and mean age of 46.1 years (SD 16.4). Associated fracture patterns accounted for 56.5% of fractures (n = 143). Trajectory analysis showed all timepoints had significant disability versus baseline, including final follow-up (p < 0.001). Elementary fractures had higher SF-36 PCS at six months (p = 0.023) and one year (p = 0.007) compared to associated fractures, but not at two years (p = 0.135) or five years (p = 0.631). The MCID in SF-36 PCS was observed in 37.3% of patients (69/185) between six months and one year, 26.9% of patients (39/145) between one and two years, and 23.3% of patients (20/86) between two and five years, highlighting the long recovery potential of these injuries. A significant proportion of patients failed to attain the MCID after five years (38.1%; 40/105). Conversion to THA occurred in 13.1% of patients (11/110 elementary and 22/143 associated fractures). Approximately two-thirds of THAs (21/33 patients; 63.6%) were performed within two years of index surgery. Conclusion: Acetabular fractures significantly impact physical function. Recovery trajectory is often elongated beyond one year, with two-thirds of our patients displaying persistent clinically relevant long-term disability.

Effect of humeral rotation on the reliability of radiographic measurements for proximal humerus fractures.

BACKGROUND: There are concerns as to the reliability of proximal humerus radiographic measurements, particularly regarding the rotational position of the humerus when obtaining radiographs. METHODS: Twenty-four patients with proximal humerus fractures fixed surgically with locked plates received postoperative anteroposterior radiographs with the humerus in neutral rotation and in 30° of internal and external rotation. Radiographic measurements for head shaft angle, humeral offset and humeral head height were performed in each humeral rotation position. Intra-class correlation coefficient was used to assess inter-rater and intra-rater reliability. Mean differences (md) in measurements between humeral positions was evaluated using one-way ANOVA. RESULTS: Head shaft angle demonstrated good-to-excellent reliability; the highest estimates for inter-rater reliability (ICC: 0.85; 95% CI: 0.76, 0.94) and intra-rater reliability (ICC: 0.96; 95% CI: 0.93, 0.98) were achieved in neutral rotation. There were significant differences in measurement values between each rotational position, with mean head shaft angle of 133.1° in external rotation, and increasingly valgus measurements in neutral (md: 7.6°; 95% CI: 5.0, 10.3°; p < 0.001) and internal rotation (md: 26.4°; 95% CI: 21.8, 30.9°; p < 0.001). Humeral head height and humeral offset showed good-to-excellent reliability in neutral and external rotation, but poor inter-rater reliability in internal rotation. Humeral head height was significantly greater using internal compared to external rotation (md: 4.5 mm; 95% CI: 1.7, 7.3 mm; p = 0.002). Humeral offset was significantly greater in external compared to internal rotation (md: 4.6 mm; 95% CI: 2.6, 6.6 mm; p < 0.001). CONCLUSIONS: Views of the humerus in neutral rotation and 30° of external rotation displayed superior reliability. Differences in radiographic measurement values, depending on humeral rotation views, can make for problematic correlations with patient outcome measures. Studies assessing radiographic outcomes following proximal humerus fractures should ensure standardized humeral rotation for obtaining anteroposterior shoulder radiographs, with neutral rotation and external rotation views likely yielding the most reliable results. LEVEL OF EVIDENCE: Level IV.

Assessing the Change in Operative Treatment Rates for Acute Midshaft Clavicle Fractures: Incorporation of Evidence-Based Surgery Results in Orthopaedic Practice.

In 2007, a randomized controlled trial (RCT) by the Canadian Orthopaedic Trauma Society (COTS) demonstrated better functional outcomes and a lower proportion of patients who developed malunion or nonunion following operative, compared with nonoperative, treatment of midshaft clavicle fractures. The primary aim of the present study was to compare the proportion of midshaft clavicle fractures treated operatively prior to and following the publication of the COTS RCT. An additional exploratory aim was to assess whether the proportion of midshaft clavicle fractures that were treated with surgery for malunion or nonunion decreased. Methods: This retrospective cohort analysis used population-level administrative health data on the residents of British Columbia, Canada. Cases were identified by International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes and procedure fee codes. Adult patients (≥18 years) with closed middle-third clavicle fractures between 1997 and 2018 were included. Multivariable logistic regression modeling compared the proportion of clavicle fractures treated operatively before and after January 1, 2007, controlling for patient factors. The Pearson chi-square test compared the proportion of fractures treated operatively for malunion or nonunion in the cohorts. Results: A total of 52,916 patients were included (mean age, 47.5 years; 65.6% male). More clavicle fractures were treated operatively from 2007 onward: 6.9% compared with 2.2% prior to 2007 (odds ratio [OR] = 3.35, 95% confidence interval [CI] = 3.03 to 3.70, p < 0.001). Male sex, moderate-to-high income, and younger age were associated with a greater proportion of operative fixation. The rate of surgery for clavicle malunion or nonunion also increased over this time period (to 4.1% from 3.4%, OR = 1.26, 95% CI = 1.15 to 1.38, p < 0.001). Conclusions: We found a significant change in surgeon practice regarding operative management of clavicle fractures following the publication of a Level-I RCT. With limited high-quality trials comparing operative and nonoperative management, it is important that clinicians, health-care institutions, and health-authority administrations determine what steps can be taken to increase responsiveness to new clinical studies and evidence-based guidelines.

Gender Diversity, Leadership, Promotion, and Opportunity Among the Members of the Orthopaedic Trauma Association (OTA).

OBJECTIVES: To demonstrate the gender distribution in leadership positions and academic promotion of Orthopaedic Trauma Association (OTA) members. METHODS: We conducted a cross-sectional examination of the 2020-2021 OTA membership cohort dataset provided by the OTA. Professional and academic information of OTA members at their site of appointment was also abstracted from publicly available online resources. Data included: gender, OTA membership category, OTA leadership position, trauma fellowship completion, trauma practice setting, level of trauma center, percentage of trauma work, year of first practice, academic rank, and university/hospital/institutional leadership role. Statistical analysis included chi-squared, Wilcoxon two-sample, and Fisher exact tests. RESULTS: 2608 OTA members were identified; 14.1% were women. Female representation was highest in the Trauma Practice Professional category (67.1%) and significantly lower in the Active category (9.1%) ( P < 0.0001). No statistically significant gender differences were observed regarding level of trauma center, percentage of trauma work, or trauma practice setting. In the Active, Clinical and Emeritus categories, men achieved a higher level of academic rank than women at their site of employment ( P = 0.003), while more men completed trauma fellowships ( P = 0.004) and had been in practice for significantly longer ( P < 0.0001). Men held more of the highest leadership positions (eg, Board of Directors) ( P = 0.0047) and the greatest number of leadership positions ( P = 0.017) within the OTA compared with women. CONCLUSION: Gender disparity exists within the upper echelon of leadership and academic representation in orthopaedic trauma. Our findings will help inform strategic policies to address gender diversity within the OTA and the broader orthopaedic trauma subspecialty.

What are the optimal targeting visualizations for performing surgical navigation of iliosacral screws? A user study.

INTRODUCTION: Complex orthopaedic procedures, such as iliosacral screw (ISS) fixations, can take advantage of surgical navigation technology to achieve accurate results. Although the impact of surgical navigation on outcomes has been studied, no studies to date have quantified how the design of the targeting display used for navigation affects ISS targeting performance. However, it is known in other contexts that how task information is displayed can have significant effects on both accuracy and time required to perform motor tasks, and that this can be different among users with different experience levels. This study aimed to investigate which visualization techniques helped experienced surgeons and inexperienced users most efficiently and accurately align a surgical tool to a target axis. METHODS: We recruited 21 participants and conducted a user study to investigate five proposed 2D visualizations (bullseye, rotated bullseye, target-fixed, tool-fixed in translation, and tool-fixed in translation and rotation) with varying representations of the ISS targets and tool, and one 3D visualization. We measured the targeting accuracy achieved by each participant, as well as the time required to perform the task using each of the visualizations. RESULTS: We found that all 2D visualizations had equivalent translational and rotational errors, with mean translational errors below 0.9 mm and rotational errors below 1.1[Formula: see text]. The 3D visualization had statistically greater mean translational and rotational errors (4.29 mm and 5.47[Formula: see text], p < 0.001) across all users. We also found that the 2D bullseye view allowed users to complete the simulated task most efficiently (mean 30.2 s; 95% CI 26.4-35.7 s), even when combined with other visualizations. CONCLUSIONS: Our results show that 2D bullseye views helped both experienced orthopaedic trauma surgeons and inexperienced users target iliosacral screws accurately and efficiently. These findings could inform the design of visualizations for use in a surgical navigation system for screw insertions for both training and surgical practice.

Fragility Fractures of the Pelvis: Current Practices and Future Directions.

PURPOSE OF REVIEW: To summarise the current evidence and clinical practices for patients with fragility fractures of the pelvis (FFP). RECENT FINDINGS: FFPs are an increasingly prevalent and recognised problem in the elderly population. Recent evidence indicates they have a significant impact on function, morbidity and mortality. While traditional management of FFPs was predominantly non-surgical, surgical options have been increasingly used, with a range of surgical methods available. To date, limited consensus exists on the optimal strategy for suitable patient selection, and clinical trials in this population have proved problematic. The management of FFPs requires a multi-faceted approach to enhance patient care, including adequate pain control, minimisation of complications and optimisation of medical management. Early return to mobilisation should be a key treatment goal to maintain functional independence. The selection of patients who will maximally benefit from surgical treatment, and the most appropriate surgical strategy to employ, remains contentious.

Risk Factors for the Development of Heterotopic Ossification Following Acetabular Fractures: A Systematic Review.

BACKGROUND: Heterotopic ossification (HO) following acetabular fractures is a common complication that may affect clinical outcomes. However, the effects of prophylactic treatment with nonsteroidal anti-inflammatory drugs or radiation therapy remain controversial. While several factors have been related to the development of HO, there is considerable uncertainty regarding their importance or effect size in the setting of acetabular surgery. Therefore, this systematic review aims to summarize the risk factors for HO following the operative fixation of acetabular fractures and clarify their interrelationships. METHODS: In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, PubMed, MEDLINE, Embase, and CINAHL databases were searched from inception to February 2021. Studies that assessed factors related to HO development among patients with operatively repaired acetabular fractures were included. Outcomes were risk factors and their effect size (p values, odds ratios, and 95% confidence intervals). RESULTS: Twenty-five studies and 1 conference abstract with a total of 3,940 patients were included. The following risk factors for HO were identified. Patient factors were increased body mass index, male sex, and increased age. Injury factors were intensive care unit (ICU) admission and length of stay, non-ICU hospitalization for >10 days, the need for mechanical ventilation for ≥2 days, abdominal and/or chest injuries, the number and type of associated fractures, traumatic brain injuries, T-type acetabular fractures, pelvic ring injuries, and hip dislocation. Care factors were a delay to surgery, extensile and posterior surgical approaches to the hip, trochanteric osteotomy, postoperative step-off of >3 mm, and a delay to prophylaxis following injury or surgery. Ethnicity, Injury Severity Score, cause of the fracture, femoral head injuries, degloving injuries, comminution, intra-articular debris, the type of bone void filler, gluteus minimus muscle preservation, prolonged operative time, and intraoperative patient position were not risk factors for developing HO. CONCLUSIONS: HO following operative fixation of acetabular fractures is not uncommon, with severe-grade HO associated with substantial disability. Careful consideration of the risk factor effect sizes and interdependencies could aid physicians in identifying patients at risk for developing HO and guide their prophylactic management. The results of this study could establish a framework for future studies. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Responsiveness of the PROMIS physical function measure in orthopaedic trauma patients.

OBJECTIVES: To compare the responsiveness of the Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF) to the 36-Item Short Form Survey Physical Component Score (SF36-PCS) in orthopaedic trauma patients from pre-injury to one year recovery. DESIGN AND SETTING: Prospective cohort study at a Level 1 trauma centre. PARTICIPANTS: Patients over the age of 18 with orthopaedic trauma injuries to the pelvis, lower extremity or upper extremity between 2017 and 2018. MAIN OUTCOMES MEASUREMENTS: The PROMIS-PF and SF36-PCS assessments were conducted at baseline, 3 months, 6 months and 12 months. Responsiveness of each measure was assessed between time points by calculating the standardized response mean (SRM), the proportions of patients exceeding minimal clinically important difference (MCID), and the floor and ceiling effects. RESULTS: Sixty-eight patients with completed assessments at every timepoint were included: mean age 44.7 years, 39 were male and mean Injury Severity Score (ISS) was 7.4 (range: 4-16). Mean time of completion for the SF-36 at all the time points was 5.6 min vs 1.7 min for the PROMIS-PF (p<0.01). The SRM was comparable between measures at all the time points. Although a greater proportion of patients achieved MCID for SF36-PCS between all the time points, this only approached statistical significance between the 6- and 12-month assessments (47.1% vs 33.8%; p = 0.15). There was a significant ceiling effect demonstrated with the PROMIS-PF at baseline and 12-month assessments, with 34 (50.0%) patients and 7 (10.3%) patients achieving the maximum scores at each time point, respectively. DISCUSSION AND CONCLUSIONS: PROMIS-PF has a more favourable responder burden based on lower time to completion and comparable responsiveness to the SF-36 PCS. However, there are limitations in responsiveness with the PROMIS-PF in patients who are higher functioning as demonstrated by the ceiling effects in patients at baseline pre-injury and at 12 months post-injury timepoints.

Gender disparity in academic orthopedic programs in Canada: a cross-sectional study.

BACKGROUND: The majority of the literature on gender disparity in orthopedic surgery is from the United States; the Canadian perspective is lacking. The objective of this study was to determine the representation of women faculty members and the proportion of women faculty in published leadership positions in academic orthopedic divisions and departments across Canada. METHODS: In this cross-sectional study, we used a Web-based search strategy to identify faculty listings for all 17 academic orthopedic programs affiliated with the Association of Faculties of Medicine of Canada for the 2018/19 academic year. For each faculty member identified, we determined gender (man or woman), professorial rank and leadership positions. We compared regional gender differences among 3 groups: schools in eastern Canada and Quebec (6), Ontario (6) and western Canada (5). Gender comparisons were made for all variables of interest. RESULTS: We identified 809 orthopedic surgeons at the 17 Canadian academic institutions, of whom 96 (11.9%) were women. In eastern Canada and Quebec, 16.2% of the faculty were women, significantly above the national average (p = 0.03). The corresponding values for Ontario and western Canada were 8.9% (p = 0.1) and 11.4% (p = 0.7). There were no significant differences in the proportions of women and men at lower levels of promotion, but significantly more men than women had attained full professorship (65 [9%] v. 1 [1%], p = 0.002). Women surgeons were not represented in leadership roles or within faculty roles of distinction. CONCLUSION: In 2018/19, women orthopedic surgeons were underrepresented in faculty positions across academic orthopedic training programs in Canada, and were disproportionately underrepresented in promoted academic faculty roles and leadership positions. These data can be used to review and educate on equity in hiring and promotion, as well as to foster mentorship and transition planning.

Surgical Management of Delayed Brachial Plexopathy After Clavicle Nonunion.

SUMMARY: Brachial plexopathy after conservative therapy or surgical treatment of clavicular fractures is an uncommon, yet serious complication that is associated with compression of the brachial plexus or the subclavian artery and vein because they traverse through the thoracic outlet. Surgical decompression of the brachial plexus is the recommended treatment if this condition is to occur. Although there are multiple reports of these cases in the literature, at present, there are no clear guidelines for their management. We are highlighting an institutional management algorithm, illustrated by a small retrospective case series, that uses a multidisciplinary approach in an effort to minimize complications associated with the management of clavicle nonunion.

Quantifying Urinary and Sexual Dysfunction After Pelvic Fracture.

OBJECTIVES: To quantify the severity of urinary and sexual dysfunction and to evaluate the relationship between urinary and sexual dysfunction, injury, and treatment factors in patients with pelvic fracture. DESIGN: Prospective cohort study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: One hundred thirteen patients with surgically treated pelvic fracture (65.5% OTA/AO 61B fractures; 7 open fractures; 74 men). INTERVENTIONS: Surgical pelvic stabilization. MAIN OUTCOME MEASURES: The 36-Item Short Form Health Survey and International Consultation Incontinence Questionnaire responses were collected at baseline, 6 months, and 1, 2, and 5 years. Patients were scored on symptoms of voiding and incontinence, and filling (for women), to derive urinary function. Sexual function was scored as a single domain. Both genders reported urinary and sexual bothersome symptoms. Regression analysis was used to isolate the importance of predictive factors on urinary and sexual function, urinary and sexual bother, and their impact on quality of life. RESULTS: Patients with pelvic fracture have significant urinary and sexual dysfunction, which is sustained or worsens over time. Male urinary function was predicted by Injury Severity Score (P = 0.03) and 61C fracture (odds ratio: 3.23, P = 0.04). Female urinary function was predicted by urinary tract injury at admission (odds ratio: 7.57, P = 0.03). Neurologic injury and anterior fixation were identified as significant predictors for male sexual function and sexual bother, whereas urological injuries were important in predicting female urinary and sexual bother (P < 0.01). Sexual function (P = 0.02) and sexual bother (P < 0.001) were important predictors of overall mental well-being in men. CONCLUSIONS: Urinary and sexual dysfunction are prevalent and sustained in men and women and do not follow the prolonged slow recovery trajectory seen in physical function. Male urinary and sexual dysfunction was closely tied to neurologic injury, whereas female urinary and sexual dysfunction was predicted by the presence of a urinary tract injury. Urinary and sexual dysfunction were important to overall mental well-being in men. LEVEL OF EVIDENCE: Prognostic Level II.

Long-Term Trajectory of Recovery Following Pilon Fracture Fixation.

OBJECTIVES: To describe the trajectory of recovery following fixation of pilon fractures from baseline to 5-year follow-up. DESIGN: Prospective cohort study. SETTING: Level-1 trauma center. PATIENTS/PARTICIPANTS: Patients with pilon fractures (OTA/AO 43.C) treated with open reduction and internal fixation. INTERVENTION: None. MAIN OUTCOMES MEASURES: Patient-reported outcome measures were measured at baseline, 6 months, 1 year, and 5 years using the Short-Form 36 Health Survey (SF-36) Physical Component Score and Mental Component Score, Short Musculoskeletal Functional Assessment, and the Foot and Ankle Outcome Score. RESULTS: One hundred two patients were enrolled: mean age was 42.6 years; 69% were males; 88% had an injury severity score of 9; 74 patients (73%) completed 1-year follow-up; 40 patients (39%) completed 5-year follow-up. Trajectory of recovery of physical function showed a significant decline between baseline and 6 months, with significant improvement between 6 months and 1 year and then ongoing but slower improvement between 1 year and 5 years. Sixty-four patients returned to baseline SF-36 Physical Component Score at 5 years. Pain was a persistent issue and remained significantly worse at 5 years when compared with baseline. Psychological well-being (SF-36 Mental Component Score) did not significantly change from baseline at 5 years. CONCLUSION: Functional recovery following open reduction and internal fixation for pilon fractures was characterized by an initial decrease in function from baseline, followed by an increase between 6 months and 1 year, and then slower but continued increases from 1 year to 5 years. Function did not return to baseline levels, pain was a persistent issue, and mental well-being showed no change from baseline at 5 years. This information may be useful when counselling patients.

Comparison of Patient-Reported Outcomes After Suprapatellar Versus Infrapatellar Nailing Techniques for Tibial Shaft Fractures: A Systematic Review and Meta-analysis.

OBJECTIVES: To compare patient-reported outcome measures (PROMs) between patients who underwent intramedullary nail (IMN) fixation for tibial shaft fractures using an infrapatellar (IP) or the newer suprapatellar (SP) approach. Secondary outcomes included fluoroscopic radiation exposure, operative time, and radiographic outcomes. DATA SOURCES: A systematic literature search of the databases Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials Study Selection. STUDY SELECTION: Level I to III studies in which patients over the age of 18 years with acute tibial shaft fractures who underwent tibial IMN fixation using an IP or SP approach for fracture fixation were assessed for inclusion. Studies with a minimum of 10 patients in each cohort that reported on postoperative patient-reported outcomes with at least 6 months of follow-up were included for analysis. DATA EXTRACTION AND SYNTHESIS: Twelve studies that reported PROMs and compared IP and SP intramedullary nailing of tibial shaft fractures were analyzed. This included 654 patients who underwent IP IMN fixation and 542 patients who underwent SP IMN fixation. A random-effects model for unadjusted/crude study estimates were pooled using inverse variance (IV) weighting for continuous variable analysis. CONCLUSIONS: This review found a significant improvement in PROM for patients with tibial shaft fractures when the SP IMN technique was used. In addition, there was a significant decrease in intraoperative fluoroscopy time consistent with other radiographic findings demonstrating improved start point accuracy and reduction with SP IMN fixation of tibial shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Comparing the responsiveness of a generic and a musculoskeletal specific functional outcome measure in orthopaedic patients with operative fixation of pelvic ring, acetabulum, or tibia fractures: a comparison between single injury and multiply injured patients.

OBJECTIVES: This study compares the responsiveness, or the ability to detect clinical change in a disease, between the generic Short Form-36 (SF-36) and musculoskeletal specific Short Musculoskeletal Functional Assessment (SMFA) patient-reported outcome measures (PROMs) in the orthopaedic trauma population. Stratified analysis was performed to compare whether responsiveness differs between patients with single or multiple orthopaedic injuries. DESIGN: Prospective case series. SETTING: Level 1 Trauma Center. PATIENTS: A total of 659 patients with orthopaedic trauma injuries to the pelvis, acetabulum, or tibia were included for analysis. There were 485 patients with a single isolated injury and 174 patients with multiple orthopaedic injuries. INTERVENTION: None. MAIN OUTCOME MEASUREMENTS: Responsiveness was calculated through the standard response mean (SRM), the proportion meeting a minimal clinically important difference, and floor and ceiling effects. RESULTS: Between baseline and 6 months the magnitude of the SRM for SF-36 was consistently greater than that of SMFA in patients with single (P < .01) and multiple injuries (P < .01). Between 6 and 12 months, there were no differences in SRM across all cohorts. The proportion of patients who achieved minimal clinically important difference was consistently higher when assessed with SF-36 compared with SMFA between baseline and 6 months (81.8% vs 68.1%, P < .0001) and between 6 and 12 months (63.3% vs 55.4%, P = .01).A ceiling effect was only observed at baseline for the SMFA with 16.6% of patients achieving the maximal level of functioning detectable. No floor effects were seen in either PROM. CONCLUSION: This study demonstrates that SF-36 has superior responsiveness versus SMFA in both polytrauma and isolated injury patients and supports the collection of SF-36 as the primary PROM in prospective orthopaedic trauma studies irrespective of whether the patient has an isolated injury or multiple injuries.

Which general functional outcome measure does a better job of capturing change in clinical status in pelvic and acetabular fracture patients? An analysis of responsiveness over the first year of recovery.

OBJECTIVE: To compare the responsiveness of the Short Form-36 (SF-36) physical component score (PCS) to the Short Musculoskeletal Function Assessment (SMFA) dysfunction index (DI) in pelvic and acetabular fracture patients over multiple time points in the first year of recovery. DESIGN: Prospective cohort study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Four hundred seventy-three patients with surgically treated pelvic and acetabular fractures (Orthopaedic Trauma Association B or C-type pelvic ring disruption or acetabular fracture) were enrolled into the center's prospective orthopaedic trauma database between January 2005 and February 2015. Functional outcome data were collected at baseline, 6 months, and 12 months. MAIN OUTCOME MEASUREMENTS: Evaluation was performed using the SF-36 Survey and Short Musculoskeletal Function Assessment. Responsiveness was assessed by calculating the standard response mean (SRM), the minimal clinically important difference (MCID), and floor and ceiling effects. RESULTS: Three hundred five patients had complete data for both outcome scores. SF-36 PCS and SMFA DI scores showed strong correlation for all time intervals (r = -0.55 at baseline, r = -0.78 at 6 months, and r = -0.85 at 12 months). The SRM of the SF-36 PCS was greater in magnitude than the SRM of SMFA DI at all time points; this was statistically significant between baseline and 6 months (P < .001), but not between 6 and 12 months (P = .29). Similarly, the proportion of patients achieving MCID in SF-36 PCS was significantly greater than the proportion achieving MCID in SMFA DI between baseline and 6 months (84.6% vs 69.8%, P < .001), and between 6 and 12 months (48.5% vs 35.7%, P = .01). There were no ceiling or floor effects found for SF-36 PCS at any time intervals. However, 16.1% of patients achieved the highest level of functioning detectable by the SMFA DI at baseline, along with smaller ceiling effects at 6 months (1.3%) and 12 months (3.3%). CONCLUSIONS: SF-36 PCS is a more responsive measure of functional outcome than the SFMA DI over the first year of recovery in patients who sustain a pelvic ring disruption or acetabular fracture. This superiority was found in using the SRM, proportion of patients meeting MCID, and ceiling effects. Furthermore, the SF-36 PCS correlated with the more disease-specific SMFA DI. LEVEL OF EVIDENCE: Prognostic Level II.
