Distal radius fractures are among the most common fractures seen in the emergency department. Closed reduction can provide definitive management when acceptable radiographic parameters are met. Repeated attempts of closed reduction are often performed to improve the alignment and avoid operative management. However, multiple reduction attempts may worsen dorsal comminution and lead to eventual loss of reduction, resulting in no demonstrable benefit. We hypothesize that compared to one closed reduction attempt, repeated closed reduction of extra-articular, dorsally angulated, displaced distal radius fractures has a low success rate in the prevention of operative fixation and improvement of radiographic parameters.

Initial and post reduction radiographs for all distal radius fractures managed at Vancouver General Hospital between 2015 and 2018 were reviewed. Inclusion criteria were based on the AO fracture classification and included types 23-A2.1, 23-A2.2 and 23-A3. Exclusion criteria included age less than 18, intra-articular involvement with more than two millimeters of displacement, volar or dorsal Barton fractures, fracture-dislocations, open fractures and volar angulation of the distal segment. Distal radius fractures that met study criteria and underwent two or more attempts of closed reduction were matched by age and gender with fractures that underwent one closed reduction. Radiographic parameters including radial height and inclination, ulnar variance and volar tilt were compared between groups.

Sixty-eight distal radius fractures that met study criteria and underwent multiple closed reduction attempts were identified. A repeated closed reduction initially improved the radial height (p = 0.03) and volar tilt (p < 0.001). However, by six to eight weeks the improvement in radial height had been lost (p = 0.001). Comparison of radiographic parameters between the single reduction and multiple reduction groups revealed no difference in any of the radiographic parameters at one week of follow up. By six to eight weeks, the single reduction group had greater radial height (p = 0.01) ulnar variance (p = 0.05) and volar tilt (p = 0.02) compared to the multiple reduction group. With respect to definitive management, 38% of patients who underwent a repeated closed reduction subsequently received surgery, compared to 13% in the single reduction group (p = 0.001).

Repeated closed reduction of extra-articular, dorsally angulated, displaced distal radius fractures did not improve alignment compared to a single closed reduction and was associated with increased frequency of surgical fixation. The benefit of repeating a closed reduction should be carefully considered when managing distal radius fractures of this nature.

Aims

The aim of this study was to determine the trajectory of recovery following fixation of tibial plateau fractures up to five-year follow-up, including simple (Schatzker I-IV) versus complex (Schatzker V-VI) fractures.

The effect of early surgery on hip fracture outcomes has received considerable study and although it has been suggested that early surgical treatment of these fractures leads to better patient outcomes, the findings are inconclusive. The American College of Surgeon's (ACS) National Surgical Quality Improvement Project (NSQIP) prospectively collects blinded, risk-adjusted patient-level data on surgical patients in over 600 participating hospitals worldwide. The primary objective of this study was to determine the proportion of ACS-NSQIP hospital patients that are currently being treated within the UK's National Institute for Health and Care Excellence (NICE) time to hip fracture surgery benchmark. The secondary objectives were to identify risk factors for missing the benchmark, and determine if the benchmark is associated with improved 30-day patient outcomes.

Patients that underwent hip fracture surgery between 2005–2013 and entered in the ACS-NSQIP database were included in the study. Counts and proportions were used to determine how frequently the NICE benchmark was met. Multivariate regression analysis was used to identify significant predictors of missing the NICE benchmark and determine if missing the benchmark was associated with 30-day mortality/complications rates.

26,006 patients met the study enrolment criteria. 71.4% of patients were treated within the NICE benchmark and 89.4% were treated by post-admission day two. Gender, dyspnea, infectious illness, bleeding disorders, preoperative hematocrit, preoperative platelet count, arthroplasty procedure type, race other than White, and hip fracture diagnosis were all statistically significant predictors of missing the benchmark (p<0.01). Meeting the NICE benchmark was not associated with reductions in major complications (OR=0.93, CI=0.83–1.05, p=0.23), nor a clinically significant difference in postoperative length of stay (LOS) (parameter estimate=0.77, p<0.01); however, it was associated with a decreased 30-day mortality (OR=0.88, CI=0.78–0.99, p=0.03) and the likelihood of minor complications (OR=0.92, CI=0.84–0.995, p=0.04).

ACS-NSQIP hospitals are currently compatible with the NICE benchmark. However, data from the ACS-NSQIP database suggests that surgical treatment within the NICE benchmark may be unnecessarily narrow. Extending the benchmark to post-operative day two did not significantly increase the risk of 30-day mortality and minor complications; nor did it extend the average LOS. Neither the NICE benchmark, nor the extended two-day standard, was associated with reductions in major complications. The findings highlight the importance of further prospective investigation to monitor the effect of time to surgery benchmarks.

To determine if intraoperative positioning in the supine or lateral position affects morbidity and mortality in orthopaedic trauma patients with femur fractures.

Retrospective cohort study of 991 patients representing 1030 femoral shaft fractures admitted to our level one trauma center between the years of 1987 to 2006. Primary outcome measures included mortality and admission to ICU. Secondary outcome measures included length of stay in hospital, length of time admitted to the intensive care unit and discharge disposition. Logistic regression analysis was performed to compare to effect of intraoperative position in addition to other known dependent variables on primary and secondary outcome measures.

Intraoperative position in the supine or lateral position had no effect on morbidity or mortality in orthopaedic trauma patients with femur fractures.

There is no difference in immediate mortality or morbidity between patients with femur fractures treated with IM nails in either the lateral or supine position. We conclude that either position is safe for the surgical stabilization of femur fractures and intraoperative position should be determined by surgeon preference.

The long-term results of patients with multiple knee ligament injuries, i.e. at least 3 ligament ruptures, including both cruciates, in patients entered prospectively onto the trauma database between 1985 and 1999, were reviewed. Forty patients with this injury had modified Lysholm scores at long term follow-up a mean of 8 years post-injury. The mode of operative treatment fell into 3 groups: direct suture or screw fixation of avulsions (Group 1), mid-substance ruptures treated with cruciate reconstruction with hamstring tendons (Group 2), or suture repairs of mid-substance ruptures (Group 3). All operative procedures were undertaken within 2 weeks of injury. Non-operative treatment involved a cast or spanning external fixator (2–4 weeks) followed by bracing. Statistical analysis was performed on the Lysholm scores.

The 40 patients in the study group were predominantly young males, 40% had polytrauma, 33% had isolated injuries. Thirteen patients (33%) had non-operative management, the remainder had early operative treatment of their ligament injuries, tailored to the type of ligament injuries identified.

Long-term patient outcome data shows statistically significant differences (p< 0.05) between the best results, in patients with direct fixation of bony avulsions (mean = 89), followed by those who had early hamstring reconstruction (mean = 79), followed by those who underwent simple ligament repairs (mean = 65). There was a statistically significant difference (p< 0.05) between the overall scores for the operative group (mean = 80) compared with the non-operative group (mean = 50).

Operative treatment of multiple ligament injuries, particularly fixation of avulsions and primary reconstruction of the posterior cruciate ligament appears to yield better results than non-operative or simple repair in the long term follow-up in this group with significant knee injuries.

There are a variety of surgical approaches available for open reduction and internal fixation of acetabular fractures. Some centres have avoided the use of the triradiate approach in the belief that it may result in a significantly higher rate of heterotopic ossification. This has not been our experience. In contrast to many centres, acetabular fractures are treated in an emergent manner, with surgery usually undertaken within the first few days post injury. It is the investigators’ belief that this may in part result in a lower rate of heterotopic ossification.

The triradiate approach has fallen out of favour in the treatment of acetabular fractures due to concerns with both wound healing and heterotopic ossification. This approach however has been utilised frequently at the Vancouver General Hospital (VGH) in the treatment of acetabular fractures. The purpose of this study was to review the results and complications of this approach experienced in the large series at VGH.

We concluded that the results of this approach are acceptable with the exposure allowing anatomical fracture reduction in the vast majority of cases. The complication rate was low, as was the rate of heterotopic ossification.

The significance of this study is to highlight that this approach remains extremely useful in the treatment of acetabular fractures, due to its ability to give excellent exposure while still having an acceptably low complication rate. We believe that the ability of our unit to operate on these injuries in an emergent manner may impart the low rate of heterotopic ossification that we have observed.

There were a total of one hundred and sixty-one acetabular fractures that were treated operatively with the triradiate approach over the period 1989 to 2001. Of these, the majority were two column injuries (79 or 49%), T type fractures (34 or 21%) and transverse fractures (17 or 11%). The average age of the patients was thirty-seven years and the average time to surgery was three days. Our early complications included five cases of failure of fixation or loss of reduction of the fracture, two cases of neurovascular injury, two cases of superficial wound infection, one case of deep wound infection and one case of wound breakdown.

The study involved examining patient hospital records and radiographs and included fracture types, patient ages, delay to surgery, post-operative complications and degree of fracture reduction and healing. Grading of heterotopic ossification was performed by reviewing the anteroposterior radiographs and using Gruen’s classification system.

Purpose: To evaluate early and late perioperative complications and long term quality of life outcomes in patients having undergone immediate open reduction and internal fixation of acute high-energy tibial plateau fractures (AO C3).

Methods: Retrospective review of 70 AO C3 tibial plateau fractures managed with immediate open reduction and internal fixation at the Vancouver General Hospital from December 1987 to April 2004. Chart and database review was conducted for early and late perioperative complications, and patients were surveyed using three quality of life instruments: SF36, SMFA, and WOMAC.

Results: 3(4.3%) patients had died at the time of follow-up. Of the remaining 67, 49(73%) could be located and were contacted for follow-up. 28 of the 49 subjects (57%) completed the mail-out surveys (20 male, 8 female). Mean age of respondents at time of follow-up was 45.2±9.0 years. 10(36%) patients were pedestrians or cyclists struck by cars, 9(32%) were injured as a result of a fall, 5(18%) were motor vehicle collisions, 2(7%) were sustained by a direct blow, and 2(7%) were sustained by twisting mechanisms. Mean time from injury to OR was 56.0+84.3 hours. Duration of follow-up was 8.9+5.3 years. 4(14%) patients had open fractures. Fixation methods included immediate ORIF with a single plate in 24(86%) cases, dual plating in 3(11%) cases, and screws alone in one (3%) case. ISS and LOS scores were 11.4+6.8 and 15.7+8.0 respectively. One patient (3%) experienced an early perioperative complication of excessive soft tissue tension post ORIF requiring delayed skin closure. Late perioperative complications included 9(32%) cases of painful hardware, 2(7%) non-unions, 2(7%) superficial infections, 1(3%) osteomyelitis and 1(3%) mal-union. No patients required amputation. SMFA and WOMAC scores were 55.3+9.6 and 29.44+23.22. SF36v scores were 40.6+10.4(PCS) and 45.1+15.8(MCS).

Conclusions: Immediate open reduction and internal fixation with careful attention to soft tissues can be a viable management option for many high energy tibial plateau fractures. Complication rates are comparable to those of delayed definitive management of these injuries.

Introduction and Aims: The use of the triradiate approach has been associated with high rates of wound dehiscence, wound infection and significant heterotopic ossification. This approach has been the favoured extensile exposure at the Vancouver General Hospital for many years. We will review the outcomes of the use of this approach in the treatment of acetabular fractures.

Method: Patients were identified from the database at Vancouver General Hospital who had their acetabular fractures treated through a triradiate approach from the period January 1989 through to December 2001. Patients with a delay of greater than three weeks from injury were excluded. A retrospective review of the hospital and out-patient records and all available radiographs was performed. Patients were contacted to determine if they required any further surgery and to assess their current functional status with appropriate outcome scores. Patients were also invited to undergo repeat radiographic assessment.

Results: Of a total of 407 acetabular fractures treated surgically, 152 open reductions were performed through the triradiate approach. The average age of these patients was 38 years and 114 (75%) of these were male. Patients referred from other hospitals totalled 128 (84%). Wound outcomes were known in 138 cases. Wound complications included five cases of wound dehiscence, of which four resolved with no undue effects. There were three cases of superficial wound infection and five cases of deep wound infection. Two of the patients with deep wound infection had sustained compound acetabular injuries and a further two had significant risk factors for infection (septicaemia from chest infection and significant soft tissue necrosis). Trochanteric osteotomy was performed in 139 (91%) cases. There were only two cases of trochanteric non-union in this series, however 21 cases required removal of painful trochanteric screws. With respect to heterotopic ossification, there was a 15% Broker III/IV incidence. In this group, the injury severity scores were higher, there was a greater delay to surgery and there was a greater need for mechanical ventilation due to multiple injuries. In the group, 24 hip reconstructions were required over the period.

Conclusion: In our centre, we found a low rate of wound dehiscence and deep wound infection associated with the triradiate approach in the treatment of acetabular fractures. Both open acetabular fractures developed deep infection. Trochanteric irritation was a problem in a number of the patients. The rate of significant hetero-topic ossification was low.
