OBJECTIVEFractures of the femur are the most incapacitating fractures. For children aged 6-14 years, there is no clear consensus as to the preferred treatment. The conventional treatment of traction and casting is no longer recommended. We report our experience in titanium elastic nailing for treatment of paediatric femoral diaphyseal fractures.

METHODSThirty patients in the age group of 6-16 years with displaced diaphyseal femoral fractures were stabilized with titanium elastic nails. Patients were followed up clinically and radiologically for a minimum period of 1 year. The final results were evaluated using Flynn's criteria. Technical difficulties and complications associated with the procedure were also analysed.

RESULTSOverall results were excellent in 20 cases and satisfactory in 10 cases. No patient had poor result. The average hospital stay was 9 days. All the fractures healed with an average time to union of 6.86 weeks. The most common complication encountered was soft tissue irritation at the nail entry site seen in 6 cases. Clinically, lengthening was noticed in 4 cases, while no patient had shortening. Malalignment was seen in only 6 cases. Perioperative difficulties encountered were failure of closed reduction seen in 6 cases and corkscrewing of nails in one case.

CONCLUSIONTitanium elastic nails are a relatively easy to use, minimally invasive, physeal-protective implant system with high rate of good and excellent outcomes in children aged 6-16 years. Technical pitfalls can be eliminated by adhering to the basic principles.

BACKGROUND: Total knee arthroplasty (TKA) is associated with considerable blood loss. Computer-assisted surgery (CAS) is different from conventional TKA as it avoids opening the intramedullary canal. Hence, CAS should be associated with less blood loss. METHODS: Fifty-seven patients were randomized into two groups of CAS and conventional TKA. In conventional group intramedullary femoral and extramedullary tibial jigs were used whereas in CAS group imageless navigation system was used. All surgeries were done under tourniquet. Total and hidden blood loss was calculated in both groups and compared. RESULTS: The mean total blood loss was 980 mL in conventional group and 970 mL in CAS group with median of 1,067 mL (range, 59 to 1,791 mL) in conventional group and 863 mL (range, 111 to 2,032 mL) in CAS group. There was no significant difference in total blood loss between the two groups (p = 0.811). We have found significant hidden blood loss in both techniques, which is 54.8% of the total loss in the conventional technique and 59.5% in the computer-assisted navigation technique. CONCLUSIONS: There is no significant difference in total and hidden blood loss in the TKA in CAS and conventional TKA. However, there is significant hidden blood loss in both techniques. There was no relation of tourniquet time with blood loss.

Background/Aims: Multiple outbreaks of multidrug-resistant organisms have been reported worldwide due to contaminated duodenoscopes. In 2015, the United States Food and Drug Administration recommended the following supplemental enhanced surveillance and reprocessing techniques (ESRT) to improve duodenoscope disinfection: 1. microbiological culture, 2. ethylene oxide sterilization, 3. liquid chemical sterilant processing system, and 4. double high-level disinfection. A systematic review and metaanalysis was performed to assess the impact of ESRT on the contamination rates. Methods: A thorough and systematic search was performed across several databases and conference proceedings from inception until January 2021, and all studies reporting the effectiveness of various ESRTs were identified. The pooled contamination rates of post-ESRT duodenoscopes were estimated using the random effects model. Results: A total of seven studies using various ESRTs were incorporated in the analysis, which included a total of 9,084 post-ESRT duodenoscope cultures. The pooled contamination rate of the post-ESRT duodenoscope was 5% (95% confidence interval [CI]: 2.3%–10.8%, inconsistency index [I2]=97.97%). Pooled contamination rates for high-risk organisms were 0.8% (95% CI: 0.2%–2.7%, I2=94.96). Conclusions While ESRT may improve the disinfection process, a post-ESRT contamination rate of 5% is not negligible. Ongoing efforts to mitigate the rate of contamination by improving disinfection techniques and innovations in duodenoscope design to improve safety are warranted.
