Hand Surgical Simulation in the Pandemic Era: A Systematic Review

Introduction: The COVID-19 pandemic and duty hour restrictions have illuminated a role for surgical simulation in trainees that permits meaningful technical experience outside the operating room. There is a need for the implementation of surgical simulation infrastructure adjacent to clinical training with practical considerations for complexity and cost. This systematic review analyzes surgical simulations that train hand surgical techniques and procedures with subjective or objective competency assessment. Method(s): A systematic review was conducted according to PRISMA- P guidelines using the PubMed, Medline, Scopus, Embase, Web of Science, and Cochrane databases. Selected search terms included procedures relevant to the field of hand surgery and various types of simulation training. Data, including skills and techniques taught and assessed, model type, equipment, cost, and emphasis placed in training for each article, were extracted. Result(s): Of 2,519 articles, 40 met inclusion criteria. Models were described as: synthetic benchtop/3D-printed (40.0%), animal (22.5%), cadaveric (20.0%), augmented and virtual reality (AR/ VR;12.5%), and other computer simulation (12.5%). Three models incorporated both a physical benchtop component and an AR/ VR component. The procedures most represented included tendon repair (30.0%), fracture fixation (27.5%), wrist arthroscopy (15.0%), and carpal tunnel release (15.0%). Sixty-five percent of articles emphasized the importance of surgical simulation in a surgeon's training. Conclusion(s): A diversity of surgical simulation models exist for the practice of various aspects of hand surgery. The existing literature demonstrates their utility for increasing expertise with surgical techniques and procedures in a low-risk setting.

Weight-bearing Allowed Following Internal Fixation of Ankle Fractures, a Systematic Literature Review and Meta-Analysis.

BACKGROUND: Postoperative management regimes vary following open reduction and internal fixation of unstable ankle fractures. Traditional postoperative nonweightbearing cast immobilization may prevent loss of fixation and protect the soft tissue envelope but may also be associated with poorer functional outcomes. This systematic review and meta-analysis aimed to compare the complication rate and functional outcomes of early weightbearing (EWB) vs late weightbearing (LWB) following open reduction and internal fixation of ankle fractures. METHODS: We performed a systematic review with a meta-analysis of controlled trials and comparative cohort studies using 3 databases. We included all studies that investigated the effect of weightbearing following internal fixation of ankle fractures in adult patients by any means. Studies that investigated mobilization but not weightbearing, non-English-language publications, and tibial Plafond fractures were excluded from this systematic review. We assessed the risk of bias using ROB 2 tools for randomized controlled trials and ROBINS-1 for cohort studies. Data extraction was performed using Covidence online software and meta-analysis by using RevMan 5.3. RESULTS: This systematic review included 10 randomized controlled trials and 4 comparative cohort studies. Most of the included studies were rated as having some concern with regard to the risk of bias. There was no significant difference in the complication rate between the protected EWB and LWB groups (the risk ratio [RR] for infection was 1.30, 95% CI 0.74, 2.30; I² = 0%; P = .36), but better functional outcome scores were detected in the EWB group only at 6 weeks postoperatively (MD =10.08, 95% CI 5.13, 15.02; I² = 0%; P ≤ .0001), with no significant difference seen at 6 or 12 months postoperatively. CONCLUSION: Based on the studies reviewed, it appears that early protected weightbearing following open reduction and internal fixation of ankle fractures does not affect surgical incision or fracture healing and is associated with better early functional outcomes at 6 weeks, but not 6 or 12 months, postoperatively.

An Overview of Rate of Infection and Mortality in Femur Fracture Patients and its Fixation during Covid-19 Pandemic

Aim: To observe the workload of fractures of the femur (shaft and distal femur) and their fixations along with complications in terms of infection and mortality at our hospital during COVID 19 pandemic. Study design: Prospective study. Place and duration of study: Dept of Orthopaedic, Ghurki Trust Teaching Hospital, Lahore from 01-03-2020 to 31-07-2020 Methodology: One hundred and thirty-one diagnosed patients with femur fracture (shaft and distal) during pandemic period of COVID were enrolled. Demographic data included (age, sex, implant type, surgical site infection (SSI) and mortality).Since study was done during COVID-19 pandemic, positivity of COVID symptoms was noted as yes/no on data collection proforma. Results: There were 105 (80.15%) males while 26 (19.84%) were females with mean age was 39.20±13.02 years. Majority of the surgical interventions were done based on Intramedullary nailing 74.05%, the second prevalent surgeries were done on AO external fixation 8.4%. Infection rate was observed in 7(5.32%) patients. No mortality was seen in any of the cases. Four infected cases were observed after intramedullary nailing procedure, two from AO external fixation and one after locking plate. Conclusion: There is no significant higher complication rate due to COVID-19 pandemic to patients whom femur fracture fixation was done. None of admitted patient suffered COVID-19 symptoms during hospitalization. It was only pointless fear about orthopaedic intervention during this interval.

Repair of frontal sinus fractures: clinical and radiological long-term outcomes.

OBJECTIVE: The long-term clinical and radiological outcomes of patients surgically treated for frontal sinus fracture were assessed. METHODS: A retrospective, single-centre analysis was conducted of patients treated for frontal sinus fracture in a tertiary trauma centre between 2000 and 2017. Patients who underwent surgical repair for frontal sinus fracture followed by clinical and radiographical evaluation for at least six months were included. RESULTS: Of 338 patients admitted with frontal sinus fracture, 77 were treated surgically. Thirty patients met the inclusion criteria for long-term follow-up. The average follow-up duration was 37 months (range, 6-132 months). Reconstruction, obliteration and cranialisation of the frontal sinus fracture were performed in 14, 9 and 7 patients, respectively. Two patients with a reconstructed frontal sinus and one with an obliterated frontal sinus developed mucoceles. One patient developed forehead disfigurement following obliteration. CONCLUSION: Long-term complications of frontal sinus repair using the chosen repair techniques are rare, but patients need to be made aware of these potential complications.
