    Abstract 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.

    Abstract 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.

    Abstract Introduction: A repeated closed reduction ("re-reduction") of a displaced distal radius fracture is a common procedure performed to obtain satisfactory alignment and avoid surgery when the initial reduction is deemed unsatisfactory. However, the efficacy of re-reduction is unclear. Compared to a single closed reduction, does a re-reduction of a displaced distal radius fracture: (1) improve radiographic alignment at the time of fracture union and, (2) decrease the rate of operative intervention?
    Materials and methods: Retrospective cohort analysis of 99 adults aged 20-99 years with extra-articular or minimally displaced intra-articular, dorsally angulated, displaced distal radius fracture with or without an associated ulnar styloid fracture who underwent a re-reduction, compared against 99 adults matched for age and sex who were managed with a single reduction. Exclusion criteria were skeletal immaturity, fracture-dislocation and articular displacement greater than 2 mm. Outcome measures included radiographic alignment at fracture union and rate of surgical intervention.
    Results: At 6-8 weeks follow-up, the single reduction group had greater radial height (p = 0.045, CI 0.04 to 3.57), and less ulnar variance (p < 0.001, CI - 3.08 to - 1.00) compared to the re-reduction group. Immediately following re-reduction, 49.5% of patients met radiographic non-operative criteria, but by 6-8 weeks follow-up, only 17.5% of patients continued to meet these criteria. Patients in the re-reduction group were treated with surgery 34.3% of the time, compared to 14.1% of the time for patients in the single reduction group (p = 0.001). In patients aged under 65 years, 49.0% of those who underwent a re-reduction were managed with surgery, compared to 21.0% of those who had a single reduction (p = 0.004).
    Conclusion: A re-reduction performed to improve radiographic alignment and avoid surgical management in this subset of distal radius fractures had minimal value. Alternative treatment options should be considered before attempting a re-reduction.

    Abstract Because consensus on the optimal surgical treatment of tongue-type calcaneal fractures is lacking, this study aimed to compare outcomes and postoperative complications of open and closed surgical treatment of these fractures. For this cases series, all patients 18 years or older who underwent operative fixation of tongue-type calcaneal fractures at 2 level I trauma centers between 2004 and 2015 were considered eligible for participation. Data on explanatory and outcome variables were collected from medical records based on available follow-up. Additionally, a systematic literature review on surgical treatment of these fractures was conducted. Fifty-six patients (58 tongue-type fractures) were included. Open reduction internal fixation was performed in 33 fractures, and closed reduction internal (percutaneous) fixation was performed in 25. More wound problems and deep infections were observed with open treatment compared with the closed approach: 10 (30%) versus 3 (12%) and 4 (12%) versus 0 (0%) procedures, respectively. In contrast, revision and hardware removal predominated in patients with closed treatments: 4 (16%) versus 1 (3%) and 9 (36%) versus 8 (24%) procedures, respectively. The systematic literature review yielded 10 articles reporting on surgical treatment for tongue-type fractures, all showing relatively good outcomes and low complication rates with no definite advantage for either technique. Both open and closed techniques are suggested as accurate surgical treatment options for tongue-type calcaneal fractures. Surgical treatment should be individualized, considering both fracture and patient characteristics and the treating surgeon's expertise. We recommend attempting closed reduction internal fixation if deemed feasible, with conversion to an open procedure if satisfactory reduction or fixation is unobtainable.

    Abstract Uganda, as do many low-middle income countries, has an overwhelming volume of orthopaedic trauma injuries. The Uganda Sustainable Trauma Orthopaedic Program (USTOP) is a partnership between the University of British Columbia, McMaster University and Makerere University that was initiated in 2007. The goal of the project is to reduce the disabilities that occur secondary to musculoskeletal trauma in Uganda. USTOP works with local collaborators to build orthopaedic trauma capacity through teaching, innovation, and research. USTOP has maintained a multidisciplinary approach to training, involving colleagues in anesthesia, nursing, rehabilitation, and sterile reprocessing. The project was initiated at the invitation of the Department of Orthopaedics at Makerere University and Mulago Hospital in Kampala. The project is a collaboration between Canadian and Ugandan orthopaedic surgeons and is driven by the needs identified by the Ugandan surgeons. The program has also worked with collaborators to develop several technologies aimed at reducing the cost of providing orthopaedic care without compromising quality. As orthopaedic trauma capacity in Uganda advances, USTOP strives to continually evolve and provide relevant support to colleagues in Uganda to ensure that changes result in sustainable improvements in patient care.

    Abstract Introduction: In the staged management of tibial pilon fractures, overlap between definitive internal fixation and external fixation pin sites has been investigated as a risk factor for infection with equivocal conclusions. Our aim was to determine if overlap or proximity of definitive internal fixation to external fixation pin sites influences the risk of deep infection.
    Patients and methods: We reviewed 280 AO/OTA 43B or 43C type distal tibia fractures in 277 patients at two level-one trauma centers. Patients underwent staged management using early temporizing external fixation followed by definitive open reduction and plate fixation. Primary outcome was the association between pin site overlap and the development of deep infection. Secondary outcome was the relationship between development of deep infection and the distance from pin site to definitive fixation.
    Results: The average duration between external fixation and definitive internal fixation was 14 days. 24% of fractures developed deep infection requiring surgical intervention. There was no association between pin site overlap and the development of deep infection (p = 0.18). There was no relationship between infection and the distance between proximal plate extent and pin site (p = 0.13).
    Discussion: We identified no association between pin site overlap and the development of deep infection. We suggest that temporizing external fixation pins should be placed so as to obtain optimal stability of the construct with lesser emphasis on aiming to be absolutely outside the zone of future fixation.

    Abstract Outcome after surgical treatment for nonunion and malunion of midshaft displaced clavicle fractures has generally been described as favorable and equal to results of acute repair. This assumption has been based on subjective criteria, however, and no direct comparison is available in the literature. This study used objective measurements of limb function to compare outcome in patients who underwent delayed operative intervention for nonunion and malunion with the outcome of patients who underwent immediate open reduction and internal fixation after displaced clavicle fracture. All patients had sustained completely displaced, closed, isolated midshaft clavicle fractures, of whom 15 had undergone acute open reduction and internal fixation with a compression plate at a mean of 0.6 months after injury (acute group). Another 15 patients had undergone delayed reconstruction with open reduction, bone grafting, and compression plate fixation for nonunion or malunion a mean of 63 months after injury (delayed group). The 2 groups were similar in age, gender, original fracture characteristics, and mechanism of injury. Complete assessment included standard history and physical examination, the Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant Shoulder Score, subjective rating of outcome satisfaction, and objective muscle strength testing using a previously validated and published protocol on the Baltimore Therapeutic Equipment (BTE) work simulator. There were no significant differences between acute fixation and delayed reconstruction groups with regard to strength of shoulder flexion (acute, 94%; delayed, 93%; P = .82), shoulder abduction (acute, 97%; delayed, 97%; P = .92), external rotation (acute, 97%; delayed, 90%; P = .11), or internal rotation (acute, 98%; delayed, 96%; P = .55). Constant scores in the acute group were superior (acute, 95; delayed, 89; P = .02), but differences in DASH scores were not significant (acute, 3.0; delayed, 7.2; P = .15). Shoulder flexion muscle endurance was significantly decreased in the delayed group (acute, 109%; delayed, 80%; P = .05). Differences in muscle endurance in other planes were not significantly different (abduction endurance: acute, 107%; delayed, 81%; P = .24). Both groups rated their satisfaction with the procedure as excellent. Late reconstruction of nonunion and malunion after displaced midshaft fractures of the clavicle is a reliable and reproducible procedure that results in restoration of objective muscle strength similar to that seen with immediate fixation; however, there are subtle decreases in endurance strength and outcome compared with acute fracture repair. This information should not be used to justify primary operative repair in isolation but is useful in decision-making when counseling patients with displaced midshaft fractures of the clavicle.
