“…Although CPCs are biodegradable, biocompatible, osteoconductive and have proper compression strength, because of their low bending and tensile strength and low fracture toughness their applications are limited to non-load bearing areas such as small cranial and maxillo-facial surgeries [136,137]. Generally, the mechanical strength of CPC is similar to that of trabecular bone, or one-fifth of that of cortical bone [138].…”

Abstract:Owing to significant advantages of bioactivity and biodegradability, biodegradable metallic materials such as magnesium, iron, and zinc and their alloys have been widely studied over recent years. Metallic wires with superior tensile strength and proper ductility can be fabricated by a traditional metalworking process (drawing). Drawn biodegradable metallic wires are popular biodegradable materials, which are promising in different clinical applications such as orthopedic fixation, surgical staples, cardiovascular stents, and aneurysm occlusion. This paper presents recent advances associated with the application of biodegradable metallic wires used in dental and orthopedic fields. Furthermore, the effects of some parameters such as the surface modification, alloying elements, and fabrication process affecting the degradation rate as well as biocompatibility, bioactivity, and mechanical stability are reviewed in the most recent works pertaining to these materials. Finally, possible pathways for future studies regarding the production of more efficient biodegradable metallic wires in the regeneration of bone defects are also proposed.

“…Its chemical name is CH 2 =C(CH 3 )COOCH 3, and in its polymerised form, polymethyl methacrylate (PMMA), it is used as a cement or grout in dentistry and orthopaedics 14. In orthopaedics, the cement is most commonly used for implant fixation, vertebroplasty, kyphoplasty and sometime as spacer.…”

Bone cement implantation syndrome (BCIS) is a well-described and potentially fatal complication of orthopaedic surgery involving pressurised bone cement. Although also described for certain spinal procedures, it is most commonly associated with cemented hip and knee arthroplasty and with cemented hemiarthroplasty following neck of femur fracture in particular.Donaldson proposed the definition of BCIS as a syndrome "characterized by hypoxia, hypotension or both and/or unexpected loss of consciousness occurring around the time of cementation, prosthesis insertion, reduction of the joint or, occasionally, limb tourniquet deflation in a patient undergoing cemented bone surgery". Other features include increased vascular resistance, cardiac arrhythmias and cardiac arrest post cement use.We describe a case of a patient who suffered a catastrophic reaction to cement during surgery for a comminuted proximal femoral fracture.

“…The powder includes the cement (acrylic) polymer along with an initiator (di-benzoyl peroxide), a radio-opacifier (zirconium oxide or barium sulfate) and often an antibiotic. The liquid contains the monomer along with a stabilizer (hydroquinone) to prevent premature polymerization, and an activator or accelerator (dimethyl-para-toluidine) to encourage polymerization at room temperature 3738. As the powdered polymer and liquid monomer are mixed, polymerization occurs, and a viscous dough is formed.…”
