The implant material at the fracture site influences fracture healing not only from biological perspective but also from mechanical perspective. Biodegradable implants such as magnesium (Mg) based alloys have shown faster secondary bone healing properties as compared to bioinert implants such as titanium (Ti). The general reasoning behind this is the benefit of Mg from biocompatibility perspectives. We studied the effect of Ti and Mg as base materials for implants from mechanical perspectives, where we focused on the displacements at the fracture site of the tibia and their influence on the stimulus for bone healing. We found out that in comparison to Ti, Mg implants have minimal problem, only which led to better mechanical stimulus at the fracture site.

Background: Low-doses of bone modifying agents (LD-BMAs) compared to those used to treat bone metastases are used in breast or prostate cancer patients on adjuvant endocrine therapy to prevent Cancer Treatment Induced Bone Loss (CTIBL). Their use is associated with an increased risk of developing Medication-Related Osteonecrosis of the Jaw (MRONJ). However, there is not clarity about strategies aimed to minimize the MRONJ risk in cancer patients at different conditions as low- vs high-doses of BMA.

Background: Osteoporosis is a widespread disease defined by a reduction in bone mass and structure, thereby increasing the risk of fragility fractures. Treatment typically involves specific medications, which either inhibit bone resorption (antiresorptive) or stimulate bone formation (anabolic) and may potentially influence the healing of osteoporotic fractures. On the other hand, metabolic disorders, immune system dysfunctions or circulatory problems can impair fracture healing.

Background And Purpose: Vascularized fibular grafting following tumor resection is an essential treatment option in limb salvage surgery. We aimed to evaluate: (I) bone healing, (II) complications and reoperations, (III) limb salvage, and (IV) survival.
Methods: We present a retrospective evaluation of a national cohort comprising 27 patients.

Introduction: Postoperative infections are a leading cause of morbidity following fracture repair. The purpose of this study is to develop a risk score predicting fracture-related infection (FRI) that will require one versus multiple revision surgeries related to infection eradication and bone healing.
Methods: This is a retrospective cohort study conducted at a single level I trauma center from 2013 to 2020.
