The dislocated hip hemiarthroplasty (HA) remains a difficult condition to treat owing to frailty, comorbidity, poor quality of bone and soft tissues. We aimed to identify parameters contributing to instability following hip HA and describe the operative management and patient outcomes.We retrospectively reviewed consecutive cases of all patients with hip fracture treated between 2004 and 2019 at a single tertiary care institution. We propensity matched patients with and without hip dislocations on a 1:2 basis for age, sex, and approach. We reviewed risk factors for HA dislocation, performed radiographic measurements, and recorded management of dislocation and further complications.Of the 1472 patients treated with HA, we included 18 patients (1.2%) who sustained at least 1 dislocation in our analysis. Of the dislocations identified, 13 and 17 occurred within 1 and 3 months postoperative, respectively. The presence of dementia and low preoperative lateral centre-edge angle were associated with increased risk of dislocation. The 2-year mortality rate was significantly higher in the dislocation group (This study highlights patient factors associated with increased dislocation risk following hip HA. A thorough preoperative assessment is indicated when presented with dislocated HA to prevent further complications.

Fragility fractures (FFs) are low-energy trauma fractures that occur at or below standing height. Among FFs, hip fractures are associated with the greatest morbidity, mortality and cost to Canadian health care systems. This review highlights the current state of medical care for hip fractures in Canada, with specific focus on the role of the multidisciplinary team. Gaps in care exist, as FFs represent a unique challenge requiring both acute and chronic management. Furthermore, there is a lack of ownership of FFs by a medical specialty. These gaps can be addressed through the use of multidisciplinary teams, which have been shown to be efficacious and cost-effective. This model of care also addresses numerous patient-identified barriers to treatment, including inadequate patient counselling. However, there is still room for improvement in both the identification of patients at risk for hip fracture and patient adherence to therapy.Les fractures de fragilisation (FF) sont des fractures qui surviennent lors d’un traumatisme léger se produisant depuis la position debout ou d’une hauteur moindre. Les fractures de la hanche sont les FF associées aux plus grands taux de morbidité et de mortalité et aux plus grands coûts pour les systèmes de santé au Canada. La présente revue s’intéresse à l’état actuel des soins médicaux pour une fracture de la hanche au pays et porte une attention spéciale au rôle de l’équipe multidisciplinaire. Des lacunes dans les soins existent et sont mises en évidence par les FF, qui posent un défi bien particulier en nécessitant une prise en charge à la fois aiguë et chronique. De plus, cette prise en charge ne relève d’aucune spécialité médicale. La correction de ces lacunes peut passer par le recours aux équipes multidisciplinaires, dont l’efficacité et la rentabilité ont été démontrées. Ce modèle de soins élimine également de nombreux obstacles au traitement signalés par les patients, y compris le counseling inadéquat. Des améliorations sont néanmoins encore nécessaires dans l’identification des patients à risque de fracture de la hanche et dans l’observance du traitement.

Background: Guidelines for urinary catheterization in patients with hip fracture recommend limiting catheter use and using intermittent catheterization preferentially to avoid complications such as urinary tract infection (UTI) and postoperative urinary retention (POUR). We aimed to compare current practices to clinical guidelines, describe the incidence of POUR and UTI, and determine factors that increase the risk of these complications. Methods: We retrospectively reviewed the charts of patients with hip fracture who presented to a single large tertiary care centre in southeastern Ontario between November 2015 and October 2017. Data collected included comorbidities, catheter use and length of stay. We compared catheter use to guidelines, and investigated the incidence of and risk factors for POUR and UTI. Results: We reviewed the charts of 583 patients, of whom 450 (77.2%) were treated with a catheter, primarily indwelling (416 [92.4%]). Postoperative urinary retention developed in 98 patients (16.8%); however, it did not affect length of stay (p = 0.2). Patients with indwelling catheters for more than 24 hours after surgery had a higher incidence of POUR than those who had their catheter removed before 24 hours (65/330 [19.7%] v. 10/98 [10.2%]) (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.06–4.38). A UTI developed postoperatively in 62 patients (10.6%). Catheter use was associated with a 6.6-fold increased risk of UTI (OR 6.6, 95% CI 2.03–21.4). Patients with indwelling catheters did not have a significantly higher incidence of UTI than those with intermittent catheterization (57/416 [13.7%] v. 2/34 [5.9%]) (p = 0.2). Patients who developed a UTI had significantly longer catheter use than patients who did not (p < 0.002). Conclusion: Indwelling catheters were used frequently, which suggests low compliance with clinical guidelines. Longer duration of catheter use led to higher rates of UTI and POUR. Further investigation of the reasons for the common use of indwelling rather than intermittent catheterization is needed.

Summary Engaging patients—defined broadly as individuals with lived experience of a given condition, family members, caregivers, and the organisations that represent them—as partners in research is a priority for policymakers, funders, and the public. Nonetheless, formal efforts to engage patients are absent from most studies, and models to support meaningful patient engagement in clinical anaesthesia research have not been previously described. Here, we review our experience in developing and implementing a multifaceted patient engagement strategy within the Regional Versus General Anesthesia for Promoting Independence After Hip Fracture (REGAIN) surgery trial, an ongoing randomised trial comparing spinal vs general anaesthesia for hip fracture surgery in 1600 older adults across 45 hospitals in the USA and Canada. This strategy engaged patients and their representatives at both the level of overall trial oversight and at the level of individual recruiting sites. Activities spanned a continuum ranging from events designed to elicit patients' input on key decisions to longitudinal collaborations that empowered patients to actively participate in decision-making related to trial design and management. Engagement activities were highly acceptable to participants and led to concrete changes in the design and conduct of the REGAIN trial. The REGAIN experience offers a model for future efforts to engage patients as partners in clinical anaesthesia research, and highlights potential opportunities for investigators to increase the relevance of anaesthesia studies by incorporating patient voices and perspectives into the research process.

Segmental bone loss continues to pose substantial clinical and technical challenges to orthopaedic surgeons. While several surgical options exist for the treatment of these complex patients, there is not a clear consensus or specific guidelines on the optimal management of these injuries as a whole. Many factors must be taken into consideration when planning surgery for these individuals. In order for these techniques to yield optimal results, each injury must be approached in a step-wise and multidisciplinary fashion to ensure that care is taken in bone and wound bed preparation, that soft tissues are healthy and free of contaminants, and that the patient's medical condition has been optimized. Through this article, we will answer relevant questions and discuss common obstacles and challenges encountered with these complex injuries. We will also review the many treatment options available or in development to address this problem.

Copyright © 2018 by the American Society of Plastic Surgeons. Background: Soft-tissue complications often dictate the success of limb salvage and the overall outcome of open fractures. Based on prior work at the R Adams Cowley Shock Trauma Center, the authors hypothesize that wounds larger than 200 cm2 are associated with a greater likelihood of both flap-related reoperation and wound complications among patients requiring soft-tissue reconstruction with a rotational flap or free tissue transfer. Methods: This study was a secondary analysis of Fluid Lavage in Open Wounds trial data that included all patients who received a rotational or free tissue flap transfer for an open fracture. The primary outcome was flap-related reoperation within 12 months of injury. The secondary outcome was wound complication, which included events treated operatively or nonoperatively. Multivariable logistic regression was used to assess the association between wound size and outcomes, adjusting for confounders. Results: Seventeen percent of the 112 patients required a flap-related reoperation. A wound size greater than 200 cm2 was not associated with reoperation in an unadjusted model (p = 0.64) or adjusting for Gustilo type (p = 0.70). The sample had an overall wound complication rate of 47.3 percent. Patients with a wound size of greater than 200 cm2 were three times more likely to experience wound complications (OR, 3.05; 95 percent CI, 1.08 to 8.62; p = 0.04) when adjusting for moderate to severe wound contamination and wound closure in the operating room. Conclusion: The findings of this study demonstrate that wound surface area is an integral determinant for wound complication following soft-tissue flap treatment, but found no association between wound surface area and flap-related reoperation rates.

Background Acetabular fractures in the elderly frequently involve segmental quadrilateral plate injury, yet no consensus exists on how to best control the femoral head medial displacement. Quadrilateral surface plates (QSP) were developed to help buttress these challenging fractures. The study aims to 1) Determine the prevalence of segmental quadrilateral plate fractures (SQPF) in elderly patients; and 2) Assess if utilization of a QSP is associated with improved acetabulum fracture reduction and outcome. Methods This was a retrospective study conducted at a level-1 trauma centre. . All patients over 60-years that sustained an acetabular fracture between 2007 and 2019 were reviewed. Pre-operative pelvic radiographs and CT imaging were reviewed for 96 patients, to assess for SQPF. From the 96 patients reviewed, over one third of patients (n = 40, 41.6%) sustained a SQPF. Patients that had an acute-THA (n = 7) were excluded as were patients that underwent an ORIF but did not have a QSP or an anterior column buttress plate (n = 3). The remaining 30 formed the study’s cohort. We assessed the ability to achieve and maintain reduction in this elderly population, and compared outcomes using traditional anterior column buttress plates (ilioingual or intra-pelvic approach) versus an intra-pelvic pre-contoured buttress suprapectineal plate (QSP). Outcome measures included: fracture reduction using the Matta classification (desirable: anatomical/imperfect and poor), re-operations, conversion to THA and Oxford Hip Score (OHS) (for the preserved hips). Results Ten patients had an ORIF with utilization of a QSP (QSP-group), and 20 had an ORIF but did not have the QSP (non-QSP-group). There was no difference in patient demographics between groups. Fracture patterns were also similar (p = 0.6). Postoperative fracture reduction was desirable (anatomical/imperfect) in 17 patients and poor in 13. Improved ability to achieve a desirable reduction was seen in the QSP-group (p = 0.02). Conversion to THA was significantly lower in patients that had a desirable fracture reduction (appropriate: 3/17; poor: 7/13). No patients in the QSP-group have required a THA to-date, compared to 10/20 patients in the non-QSP-group (p = 0.01). The mean time to THA was 1.6 ± 2.1 year. There was no difference in OHS between the two groups (34.4 ± 10.3). Conclusion Elderly acetabulum fractures have a high incidence (approaching 40%) of segmental QPF. Desirable (anatomical/imperfect) fracture reduction was associated with improved outcome. The use of a QSP was associated with improved ability to achieve an appropriate reduction. A QSP should be considered as they are both reliable and reproducible with a significantly improved fracture reduction and lower conversion to THA.

OBJECTIVE To determine if geriatric intertrochanteric hip fracture patients achieve equivalent postoperative functional status after management with either a short (180-200 mm) or a long (260-460 mm) InterTAN intramedullary device. DESIGN Retrospective review of a prospective randomized control trial. SETTING Four Level I Trauma Centers. PATIENTS/PARTICIPANTS One hundred eight patients with OTA/AO classification 31A-1 and 31A-2 intertrochanteric hip fractures were included in the study. INTERVENTION Internal fixation using an IT device. MAIN OUTCOMES MEASURES Primary outcomes included Functional Independence Measure and Timed Up and Go. Secondary outcomes included blood loss, surgical time, length of stay, adverse events, and mortality. RESULTS Seventy-one short and 37 long IT patients met study inclusion criteria. Demographics were similar between groups. There was no difference in Functional Independence Measure or Timed Up and Go scores between the 2 IT groups at any of the time points collected. Mean operative time was lower in the short IT group than in the long IT group (60 vs. 73 minutes; P = 0.021). A higher proportion of long IT patients had reamed constructs (95% vs. 48% short IT, P < 0.001). Postoperative blood loss was significantly higher in the long IT group without a significant influence on the number of patients requiring transfusion (P = 0.582) or average units transfused (P = 0.982). There was no significant difference in the proportion of postoperative adverse events between the 2 cohorts despite a higher number of peri-implant femur fractures in the short IT group than in the long IT group (5 vs. 1, P = 0.350). CONCLUSIONS Postoperative functional status was not influenced by the length of IT device in the management of geriatric intertrochanteric hip fractures. LEVEL OF EVIDENCE Therapeutic Level III.

Objectives: To compare outcomes in elderly patients with intertrochanteric hip fractures treated with either the sliding hip screw (SHS) or InterTAN intramedullary device (IT). Design: Prospective, randomized, multicenter clinical trial. Setting: Five level 1 trauma centers. Patients: Two hundred forty-nine patients 55 years of age or older with AO/OTA 31A1 (43) and OA/OTA 31A2 (206) fractures were prospectively enrolled and followed for 12 months. Intervention: Computer generated randomization to either IT (n = 123) or SHS (n = 126). Main Outcome Measurements: The Functional Independence Measure (FIM) and the Timed Up and Go test (TUG) were used to measure function and motor performance. Secondary outcome measures included femoral shortening, complications, and mortality. Results: Demographics, comorbidities, preinjury FIM scores and TUG scores were similar between groups. Patients (17.2%) who received an IT had limb shortening greater than 2 cm compared with 42.9% who received an SHS (P < 0.001). To determine the importance of preinjury function and fracture stability, we analyzed the subgroup of patients with the ability to walk 150 m independently preinjury and an OA/OTA 31A-2 fracture (n = 70). In this subgroup, patients treated with SHS had greater shortening and demonstrated poorer FIM and TUG scores compared with patients treated with an IT. Conclusions: Overall, most patients with intertrochanteric femur fractures can expect similar functional results whether treated with an intramedullary or extramedullary device. However, active, functional patients have an improved outcome when the InterTAN is used to treat their unstable intertrochanteric fracture. Level of Evidence: Therapeutic Level I.

Despite increased advocacy for patient safety and several large-scale programs designed to reduce preventable harm, most notably surgical checklists, recent data evaluating entire health systems suggests that we are no further ahead in improving patient safety and that hospital complications are no less frequent now than in the 1990s. We suggest that the failure to systematically measure patient safety is the reason for our limited pro gress. In addition to defining patient safety outcomes and describing their financial and clinical impact, we argue why the failure to implement patient safety measurement systems has compromised the ability to move the agenda forward. We also present an overview of how patient safety can be assessed and the strengths and weaknesses of each method and comment on some of the consequences created by the absence of a systematic measurement system.

[Introduction][1] In comparison with the frequently used modified Kocher approach, the extensor digitorum communis (EDC) splitting approach allows improved access to the anterior half of the radial head, which is most commonly fractured, while reducing the risk of iatrogenic injury to the lateral collateral ligament. [Step 1: Make the Incision (Modified Kocher Approach)][2] Make an oblique 7-cm lateral incision beginning at the proximal edge of the lateral epicondyle and extending distally over the center of the radial head toward the posterior ulnar border of the extensor carpi ulnaris muscle belly. [Step 2: Develop the Interval Between the Anconeus and the Extensor Carpi Ulnaris][3] Identify and develop the intermuscular interval between the anconeus and the extensor carpi ulnaris. [Step 3: Perform the Lateral Elbow Capsulotomy][4] Longitudinally incise the lateral elbow capsule and annular ligament anterior to the lateral ulnar collateral ligament. [Step 4: The Extended Modified Kocher Approach][5] Extend the exposure by elevating the common extensor origin (extensor carpi radialis brevis, EDC, and extensor carpi ulnaris) proximally off the lateral epicondyle and reflect it anteriorly. [Step 5: Make the Incision (EDC Splitting Approach)][6] Make a longitudinal oblique 5 to 6-cm lateral incision beginning at the proximal edge of the lateral epicondyle and extending distally over the radial head toward the Lister tubercle. [Step 6: Identify and Split the EDC][7] The EDC tendon is identified and bisected longitudinally starting proximally at its origin on the lateral epicondyle and extending 20 mm distally from the radiocapitellar joint. [Step 7: Perform the Lateral Elbow Capsulotomy][8] The annular ligament and joint capsule are then incised collinear with the EDC split anterior to the equator of the capitellum. [Step 8: Extended EDC Splitting Approach][9] Extend the exposure by detaching the anterior half of the EDC tendon and the extensor carpi radialis brevis tendon from the lateral epicondyle. [Step 9: Layered Closure][10] Perform an interrupted layered closure. [Results][11] In our recent cadaveric study, we quantitatively compared the modified Kocher and EDC splitting approaches in order to determine which provided the greatest exposure of the anterior aspect of the radial head, which is most commonly fractured.
