Use of Virtual Reality in the Education of Orthopaedic Procedures: A Randomised Control Study in Early Validation of a Novel Virtual Reality Simulator.

Background Virtual reality (VR) simulation is a potential solution to the barriers surgical trainees are facing. There needs to be validation for its implementation within current training. We aimed to compare VR simulation to traditional methods in acquiring surgical skills for a TFN-ADVANCED™ Proximal Femoral Nailing System (TFNA; DePuy Synthes, Auckland, New Zealand) femoral nailing system. Methods Thirty-one surgical trainees were randomised to two groups: traditional-training group (control group) and a VR-training group (intervention group) for insertion of a short cephalomedullary TFNA nail. Both groups then inserted the same TFNA system into saw-bone femurs. Surveys evaluated validity of the relevant activities, perception of simulation, confidence, stress and anxiety. The primary outcomes were tip-apex distance (TAD) and user anxiety/confidence levels. Secondary outcomes included number of screw- and nail-guidewire insertion attempts, the time taken to complete and user validity of the VR system. Results There was no statistical difference in TAD between the intervention and control groups (9mm vs 15mm, p=0.0734). The only TAD at risk of cut-out was in the control group (25mm). There was no statistical difference in time taken (2547.5ss vs 2395ss, p=0.668), nail guide-wire attempts (two for both groups, p=0.355) and screw guide-wire attempts (one for both groups, p=0.702). The control group versus intervention had higher anxiety levels (50% vs 33%) and had lower confidence (61% vs 84%). Interpretation There was no objective difference in performance on a saw-bone model between groups. However, this VR simulator resulted in more confidence and lower anxiety levels whilst performing a simulated TFNA. Whilst further studies with larger sample sizes and exploration of transfer validity to the operating theatre are required, this study does indicate potential benefits of VR within surgical training.

The missing piece of the trauma armoury-medial femoral condyle plate.

Fixation of distal femoral fractures is often challenging due to the fracture configuration and associated poor bone quality. Dual plating (lateral and medial) has become an acceptable option to provide improved stability versus a single plate fixation. Though there are several commercially available anatomically designed plates for the lateral femoral condyle, there is no anatomic plate available in UK specifically for medial fixation of distal femur fractures. Our aim is to determine the best suited pre-contoured plate for stabilising the medial femoral condyle (MFC). Right sided femur sawbones were used to determine how well 18 different pre-contoured anatomical plates (Depuy Synthes, Leeds, UK) fit the medial femoral condyle. Some of these had variable angle (VA) option. Lift off, fit and notch penetration were assessed and recorded independently by 4 orthopaedic trauma surgeons. The number and distribution of screws in the MFC that each plate allowed was also determined. To do this the MFC was divided into quadrants: Proximal anterior (PA), distal anterior (DA), proximal posterior (PP) and distal posterior (DP). The ipsilateral anterolateral proximal tibial (VA and 4.5 mm non-VA), PHILOS, posteromedial proximal tibial and ipsilateral lateral extra-articular distal humeral plate offered good sagittal fit, less than 2 mm lift off at the condyles and no diaphyseal lift off. Plate positioning in the PA quadrant offered the best fit. The ipsilateral anterolateral proximal tibial plates (VA) and PHILOS allowed at least 4 screws to be placed in the PA and 2 in the PP quadrant with no notch penetration. The Tomofix provided good fit, but all 4 screws were in PA quadrant, with distal screws causing notch penetration. The non-VA and PHILOS plates did not offer the VA advantage. The ipsilateral anterolateral proximal tibial VA plates provided the best anatomical fit for the MFC with the greatest number of screws in the condylar quadrants with the option of variable angle screw placement.

Distal femoral fractures: A comparison between single lateral plate fixation and a combined femoral nail and plate fixation.

OBJECTIVES: Distal femoral fractures occur in patients with osteoporotic bone and also as a consequence of high energy trauma. The recognised treatment options include closed or open reduction of the fracture and fixation using a locking plate or a femoral nail. Both these fixation modalities have some drawbacks. There is a risk of metalwork failure with single lateral locking plates and limited distal fixation with intramedullary nails. Since January 2018, we started using augmented fixation of distal femoral fractures using a combination of a retrograde femoral nail and a lateral locking plate. This study compares the outcomes of single lateral femoral plating (SLP) and combined nail-plate fixation (NPF). METHODS: This is a single centre retrospective case control study including all patients who sustained distal femoral fractures (OTA 33-A2, 33-A3, 33-C, 33-V3B and 33-V3D) over the study period. Outcomes for SLP were compared to NPF. The principal outcome measure was fracture union. Secondary outcome measures were reoperation rate, mortality and post-operative weight bearing status. RESULTS: 67 distal femoral fractures were included in the study. 19 patients had peri­prosthetic fractures. 40 were treated by SLP, 27 were managed with NPF.  23 (58%) patients in the SLP group were given instructions to non-weight bear or Toe touch weight bear for 6 weeks post-surgery compared to 1 (4%) in the NPF group (p = 0.000004). 7 (18%) patients treated with SLP had metalwork failure due to a non-union compared to none treated with NPF (p = 0.04). 11 fractures in the SLP group failed to unite compared to no non-unions in the NPF group (p = 0.01). These differences were magnified when assessing older (>50 years old) patients. CONCLUSIONS: Augmented fixation of distal femoral fractures using a nail plate fixation provided significantly higher union and enabled early weightbearing compared to single plate fixation. We recommend nail plate fixation for the treatment of distal femoral fractures, particularly in osteoporotic fractures.

Current Perspectives on the Management of Bone Fragments in Open Tibial Fractures: New Developments and Future Directions.

Open tibial fractures may be associated with bone loss at the time of the injury or following surgical debridement of the fracture. This article discusses the various treatment options available and the latest developments surrounding the management of free bone fragments in open tibial fractures.

Integrating elements of teddy bear therapy into cognitive behavioral therapy for a child with obsessive-compulsive disorder: A case study.

PROBLEM: Childhood obsessive-compulsive disorder (OCD) can chronically affect functioning across a multitude of areas. Cognitive behavioral therapy (CBT) is well-evidenced as an effective treatment option, however, there is less research on how CBT for OCD can best be adapted to meet the specific needs of younger children. Integrating CBT with forms of therapy that incorporate play and externalization may be particularly appropriate for this age group. However, more research is needed detailing how this could be carried out in clinical settings. METHODS: This study meets this need by describing the treatment of an 8-year-old boy with OCD. An evidence-based CBT approach was used integrated with teddy-bear therapy (TBT). This study employs a single-case A-B design to explore the acceptability and benefits of using an integrated CBT/TBT treatment approach. FINDINGS AND CONCLUSIONS: A reduction in ritualistic behavior and anxiety was seen following treatment, with qualitative feedback from the client and his family showing the inclusion of TBT to be experienced as acceptable and useful. All therapy goals were met by the end of treatment, though the parental scores on the Revised Child Anxiety and Depression Scale indicated ongoing clinically significant OCD symptoms. Implications for clinical practice and future research are discussed.

Secondary Prevention of Hip Fragility Fractures During the COVID-19 Pandemic: Service Evaluation of "MRS BAD BONES".

BACKGROUND: Management of osteoporosis is an important consideration for patients with femoral neck fractures due to the morbidity and mortality it poses. The input of orthogeriatric teams is invaluable in coordinating secondary fragility fracture prevention. The COVID-19 pandemic resulted in the rapid restructuring of health care teams and led to the redeployment of orthogeriatricians. OBJECTIVE: This study aimed to determine the impact COVID-19 had on the secondary prevention of fragility fractures among patients with femoral neck fractures, and to optimize management in this population. METHODS: A retrospective audit was conducted of patients with femoral neck fractures before and after the lockdown in response to the COVID-19 pandemic in the United Kingdom. A reaudit was conducted following the development of our new mnemonic, "MRS BAD BONES," which addressed key factors in the assessment and management of osteoporosis: medication review, rheumatology/renal advice, smoking cessation; blood tests, alcohol limits, DEXA (dual energy X-ray absorptiometry) scan; bone-sparing medications, orthogeriatric review, nutrition, exercise, supplements. The Fisher exact test was used for comparison analyses between each phase. RESULTS: Data for 50 patients were available in each phase. The orthogeriatric team reviewed 88% (n=44) of patients prelockdown, which fell to 0% due to redeployment, before recovering to 38% (n=19) in the postintervention period. The lockdown brought a significant drop in the prescription of vitamin D/calcium supplements from 81.6% (n=40) to 58.0% (n=29) (P=.02); of bone-sparing medications from 60.7% (n=17) to 18.2% (n=4) (P=.004), and DEXA scan requests from 40.1% (n=9) to 3.6% (n=1) (P=.003). Following the implementation of our mnemonic, there was a significant increase in the prescription of vitamin D/calcium supplements to 85.7% (n=42) (P=.003), bone-sparing medications to 72.4% (n=21) (P<.001), and DEXA scan requests to 60% (n=12) (P<.001). CONCLUSIONS: The redeployment of the orthogeriatric team, due to the COVID-19 pandemic, impacted the secondary prevention of fragility fractures in the study population. The "MRS BAD BONES" mnemonic significantly improved management and could be used in a wider setting.

Time to Initial Debridement and wound Excision (TIDE) in severe open tibial fractures and related clinical outcome: A multi-centre study.

BACKGROUND: Recent national (NICE) guidelines in England recommend that initial debridement and wound excision of open tibial fractures take place within 12 h of the time of injury, a change from the previous target of 24 h. This study aims to assess the effect of timing of the initial debridement and wound excision on major infective complications, the impact of the new guidance, and the feasibility of adhering to the 12 h target within the infrastructure currently existing in four major trauma centres in England. METHODS: A retrospective review was performed of Gustilo-Anderson grade 3B open tibial fractures presenting acutely to four Major Trauma Centres (MTCs) in England with co-located plastic surgery services over a ten-month period. The incidence of deep infective complications was compared between patients who underwent initial surgery according to the new NICE guidance and those who did not. Patients warranting emergency surgery for severely contaminated injury, concomitant life-threatening injury and neurovascular compromise were excluded. Multi-variable logistic regression analysis was performed to assess the effect of timing of surgical debridement on development of deep infective complications. RESULTS: 112 patients with 116 fractures were included. Six fractures (5.2%) developed deep infective complications. 38% (n = 44) underwent primary debridement within 12 h and 90% within 24 h. There was no significant difference in the incidence of major infective complications if debrided in less than or greater than 12 h (4.5% vs 5.6%, p = 1.00). Logistic regression found no significant relationship between timing of wound excision and development of deep infection. There was no significant decrease in mean time to debridement following introduction of new national guidance (13.6 vs 16.1 h) in these four MTCs. CONCLUSION: Overall, the rate of deep infection in high energy open tibial fractures managed within the four major trauma centes is low. Achieving surgical debridement within 12 h is challenging within the current infrastructure, and it is unclear whether adhering to this target will significantly affect the incidence of severe infective complications. Debridement within 24 h appears achievable. If a 12-h target is to be met, it is vital to ensure dedicated orthoplastic capacity is adequately resourced.
