Abstract
BACKGROUND Plating techniques for the fixation of foot fractures can utilize pre-contoured region-specific plates or non-anatomic non-specific mini-fragment plating systems, however there is limited published data describing complication rates. METHODS This study reviewed the complication rates and performed a cost analysis of 45 foot fractures that had fixation with the use of mini-fragment non-anatomic implants, comparing them to a series from the same centre fixed using anatomic implants and the published literature. RESULTS Complication rates seemed equivalent. Cost analysis demonstrated that non-anatomic implants were more expensive on average. CONCLUSIONS Non-anatomic mini-fragment fixation is an appropriate method for use in a variety of foot trauma situations, with comparable complication rates to pre-contoured implants, although the potential for cost savings has not been realized in this patient cohort.

Abstract
Bone fractures often require fixation devices that frequently need to be surgically removed. These temporary implants and procedures leave the patient more prone to developing medical device-associated infections, and osteomyelitis associated with trauma is a challenging complication for orthopedists. In recent years, biodegradable materials have gained great importance as temporary medical implant devices, avoiding removal surgery. The purpose of this systematic review was to revise the literature regarding the use of biodegradable bone implants in fracture healing and its impact on the reduction of implant-associated infections. The systematic review followed the PRISMA guidelines and was conducted by searching published studies regarding the in vivo use of biodegradable bone fixation implants and its antibacterial activity. From a total of 667 references, 23 studies were included based on inclusion and exclusion criteria. Biodegradable orthopedic implants of Mg-Cu, Mg-Zn, and Zn-Ag have shown antibacterial activity, especially in reducing infection burden by MRSA strains in vivo osteomyelitis models. Their ability to prevent and tackle implant-associated infections and to gradually degrade inside the body reduces the need for a second surgery for implant removal, with expectable gains regarding patients’ comfort. Further in vivo studies are mandatory to evaluate the efficiency of these antibacterial biodegradable materials.

Abstract
Adding gentamicin to silk fibroin enhances both the antibacterial performance and degradation rate of silk-based materials. The increased material degradation rate can affect the strength of early internal fixation, resulting in internal fixation failure. This study sought to adjust the gentamicin concentration to control the material degradation rate, thereby better meeting clinical application requirements. The in vitro degradation, water absorption rate, and expansion rate of silk-based materials containing different gentamicin concentrations were studied. A gentamicin-loaded silk-based screw was implanted into the femurs of New Zealand rabbits. Micro-computed tomography was used to measure the screw diameter, which was then used to calculate the degradation rate. The specimens were stained with hematoxylin and eosin and Masson's trichrome. The in vitro results revealed increasing material degradation rates with increasing gentamicin concentration but no significant differences in water absorption rates with different gentamicin concentrations. The degradation rates of gentamicin-loaded (4 mg/g) silk-based rod-like materials were approximately 11.08% at three months in vitro and 9.4% in the animal experiment. The time for complete degradation was predicted from the fitting curve to be approximately 16 months. No inflammatory hyperplasia was observed in bone or soft tissue. The degradation and biocompatibility of the material containing 4 mg/g gentamicin meet clinical application requirements, and previous experimental results demonstrate good antibacterial performance of materials containing this gentamicin concentration.

Abstract
The optimal surgical treatment of intertrochanteric femur fractures (ITF) to minimize the increased mortality in geriatric patients with high anesthetic risk was investigated by comparing closed external fixation (EF), a minimal invasive and biological osteosynthesis technique, proximal femoral nail (PFN) and hemiarthroplasty (HA) methods.Three different surgical methods were performed to 167 patients who were admitted to our clinic for ITF between 2014 and 2020 and considered at high risk (American Society of Anesthesiologists III - American Society of Anesthesiologists IV) by the Anesthesiology and Reanimation Department. Patients with multi-trauma, osteoarthritis, those with malignancies and developmental hip dysplasia were excluded from the study. Group I included patients who underwent closed reduction - external fixation (n = 46), Group II included patients who underwent partial arthroplasty (n = 77), and Group III included those who received PFN (n = 44). All fractures were classified according to the Modified Evans (Kyle) method and divided into 2 categories as type 1-2 (stable) and type 3-4 (unstable).The mean operation duration was 23 minutes and follow-up time was 14 months in Group 1, in which there was no in-hospital mortality. Five patients died due to non-operative reasons within 1 year. The mean operation duration and follow-up time in Group 2 were 40 minutes and 12 months, respectively. Six patients (7.8%) died during the operation or hospitalization, while 17 patients died due to comorbidities within 1 year. In Group 3, the mean operation duration and follow-up time were 40 minutes and 13 months, respectively. One patient died during the operation and 1 patient (n = 2, 4.5%), within 24 hours in the postoperative intensive care unit. Seven patients died due to comorbidities within 1 year. Statistical analysis revealed that the mean duration of operation, postoperative hospital stay, overall mortality and blood product transfusion amount were significantly lower in the EF group compared to other treatment methods.Closed EF is the most reliable surgical method that can minimize mortality in geriatric patients compared to other surgical options, due to the short duration of the operation, no evacuation of the fracture hematoma, early mobilization, lack of blood transfusion requirement, and early union.

Abstract
Magnesium (Mg) based implants such as plates and screws are often preferred to treat bone defects because of the positive effects of magnesium in bone growth and healing. Their low corrosion resistance, however, leads to fast degradation and consequently failure before healing was completed. Previously, we developed Mg doped titanium nitrate (TiN) thin film coatings to address these limitations and demonstrated that <10 at% Mg doping led to enhanced mineralization in vitro. In the present study, in vivo performance of (Ti,Mg)N coated Ti6Al4V based plates and screws were studied in the rabbit model. Bone fractures were formed on femurs of 16 rabbits and then fixed with either (Ti,Mg)N coated (n = 8) or standard TiN coated (n = 8) plates and screws. X-ray imaging and μCT analyses showed enhanced bone regeneration on fracture sites fixed with (Ti,Mg)N coated plates in comparison with the Mg free ones. Bone mineral density, bone volume, and callus volume were also found to be 11.4, 23.4, and 42.8% higher, respectively, in accordance with μCT results. Furthermore, while TiN coatings promoted only primary bone regeneration, (Ti,Mg)N led to secondary bone regeneration in 6 weeks. These results indicated that Mg presence in the coatings accelerated bone regeneration in the fracture site. (Ti,Mg)N coating can be used as a practical method to increase the efficiency of existing bone fixation devices of varying geometry.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) injury is a common ligament injury to the knee joint, and often lead to limited function, osteoarthritis after knee trauma, secondary damage to meniscus and cartilage, and impaired quality of life. ACL reconstruction is the gold standard surgical treatment for ACL injury, and ligament fixation after reconstruction is the key factor of ACL reconstruction success. However, the optimal fixation device for ACL reconstruction remains unclear. This study aims to evaluate the efficacy and safety of different fixation devices and to find the best fixation device for ACL reconstruction. METHODS The PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Chinese Biomedicine Literature will be searched to identify relevant studies from inception to December 2018. We will include randomized controlled trials (RCTs) comparing the effects of different fixation devices fixed on the femoral side in arthroscopically assisted ACL reconstruction. Risk of bias assessment of the included RCTs will be conducted according to the Cochrane Handbook 5.1.0. A Bayesian network meta-analysis (NMA) will be performed using R software. RESULTS The results of this NMA will be submitted to a peer-reviewed journal for publication. CONCLUSION This NMA will summarize the direct and indirect evidence to evaluate the effect of different fixation devices for ACL reconstruction.

Abstract
Anterior cruciate ligament reconstruction (ACLR) is an accepted and established surgical technique for anterior cruciate ligament (ACL) injuries and is now being practiced across the globe in increasing numbers. Although most patients get good to excellent results in the short-term after ACLR, its consequences in the long-term in prevention or acceleration of knee osteoarthritis (OA) are not yet well-defined. Still, there are many debatable issues related to ACLR, such as the appropriate timing of surgery, graft selection, fixation methods of the graft, operative techniques, rehabilitation after surgery, and healing augmentation techniques. Most surgeons prefer not to wait long after an ACL injury to do an ACLR, as delayed reconstruction is associated with secondary damages to the intra- and periarticular structures of the knee. Autografts are the preferred choice of graft in primary ACLR, and hamstring tendons are the most popular amongst surgeons. Single bundle ACLR is being practiced by the majority, but double bundle ACLR is getting popular due to its theoretical advantage of providing more anatomical reconstruction. A preferred construct is the interference fixation (Bio-screw) at the tibial site and the suspensory method of fixation at the femoral site. In a single bundle hamstring graft, a transportal approach for creating a femoral tunnel has recently become more popular than the trans-tibial technique. Various healing augmentation techniques, including the platelet rich plasma (PRP), have been tried after ACLR, but there is still no conclusive proof of their efficacy. Accelerated rehabilitation is seemingly more accepted immediately after ACLR.

Abstract
The aim of this study is to compare the hold in bone of Meniscus Arrows and Smart Nails, followed by the report of the results of the clinical application of Meniscus Arrows as fixation devices. First, pull-out tests were performed to analyse the holdfast of both nails in bone. Statistical analysis showed no significant difference; therefore, the thinner Meniscus Arrow was chosen as fixation device in the patient series of two patients with a symptomatic Osteochondritis dissecans fragment and three patients with an osteochondral fracture of a femur condyle. The cartilage margins were glued with Tissuecoll. All fragments consolidated. Second look arthroscopy in three patients showed fixed fragments with stable, congruent cartilage edges. At an average follow-up period of 5 years no pain, effusion, locking, restricted range of motion or signs of osteoarthritis were reported. Based on the results of the pull-out tests and available clinical studies, Meniscus Arrows and Smart Nails are both likely to perform adequately as fixation devices in the treatment of Osteochondritis dissecans and osteochondral fractures in the knee. They both provide the advantage of one stage surgery. However, based on their smaller diameter, the Meniscus Arrows should be preferred for this indication.
