Abstract
Background: Orthopaedic and Trauma surgery is expected to undergo profound transformation as a result of the adoption of 3D technology. Among the various applications, patient specific manufacturing of splints and casts would appear to be, particularly in children, an interesting implementation. This study aims to assess the safety of patient specific 3D casts obtained with a newly developed 3D-scanning devise in a small case series. We therefore conducted a clinical outcome and pre-marketing study in 10 consecutive patients with distal radius fractures treated at an Academic Level I Pediatric Trauma Center. After the application of the 3D cast, patients underwent three consecutive evaluations in the following 21 days. The main outcome measurements were: pain, skin lesions and general comfort, and acceptance of the cast. The three domains were measured with the Visual Analogue Scale (VAS), the NPUAP/EPUAP classification and the Positive affect-Negative affect Scale for Children (PANAS-C), the Self-Assessment Manikin (SAM) clinical psychology tests and a Likert-type five item questionnaire, respectively. A final mechanical analysis of the cast was carried out to confirm product integrity. Results: The results obtained were consistently positive in the investigated domains of general comfort, efficacy of contention and mechanical integrity of the 3D-printed cast as well as in the practicability of the supply chain. Conclusions: This study provides Level IV evidence that patient specific 3D printed casts obtained with a specifically designed software were safe in the management of “buckle” fractures of the distal radius in children. These results encourage to extend the technology to the treatment of more demanding fractures.

Abstract
BACKGROUND More than 80% of the population suffer from low back pain at some time during their lives. An orthopedic device (LSM-01) will be used to alleviate back pain caused by muscle tension. LSM-01, which has a rotating roller, stimulates meridian-muscles around the governor vessel, bladder meridian, and gall bladder meridian. METHODS This study will be a randomized, single-blinded, sham-controlled, parallel-group, pilot clinical trial. Subjects will be randomly allocated to the treatment group (LSM-01) or the control group (sham device). The duration of the clinical trial will be 2 weeks. The primary outcomes will be measured using the visual analog scale; the secondary outcomes will include pressure pain threshold, Oswestry Disability Index, and Patient Global Impression of Change. Statistical analysis will be performed for the full study population. Analysis of covariance will be conducted to identify differences in pain before and after the application of the device. DISCUSSION This clinical trial will evaluate the safety and efficacy of the LSM-01 device. As a pilot study, this investigation includes a limited number of subjects. The results of this pilot trial will form a basis for a large-scale clinical trial, which will be conducted in the future. CLINICAL TRIAL REGISTRATION This study protocol is registered with the Clinical Research Information Service (CRIS) of Korea. Clinical trial registration number: CRIS-KCT0006425. Registered: October 5, 2021; https://cris.nih.go.kr/cris/search/detailSearch.do?search_lang=E&search_page=L&pageSize=10&page=undefined&seq=20056&status=5&seq_group=20056.

Abstract
PURPOSE We have evaluated the effect of internal and external osteosynthesis devices on the efficacy of vancomycin treatment in a rabbit model of methicillin-resistant Staphylococcus aureus (MRSA)-induced post-traumatic osteomyelitis. METHODS Double tibial osteotomies in female New Zealand rabbits were performed, inoculated with a MRSA strain, then fixed with an intramedullary rod. A debridement was performed 4 days later for each rabbit, and a bacterial count in pus was determined (B1). In the first group (G1), the osteosynthesis material was removed and replaced by a new sterile nail. In the second group (G2), the intramedullary rod was removed and then replaced by an external fixator. Immediately after surgery, G1 and G2 rabbits were treated with vancomycin (60 mg/kg twice a day). The animals were sacrificed at the end of a 5-day period, and a bacterial count in pus was performed again (B2). RESULTS The difference of log(10) colony forming units per milliliter (CFU/ml) (B2-B1) was -1.2 +/- 0.5 and -2.9 +/- 1.1, respectively, for G1 and G2. CONCLUSION The efficacy of vancomycin treatment increased after removal of the internal osteosynthesis device.
