Micro-surgical instruments are a new application for mesoscale ceramics formed using the lost mold-rapid infiltration forming (LM-RIF) process. Instrument strength and reliability are the foremost concerns for this sensitive application. It is hypothesized that increasing grain size can improve the damage tolerance of the parts associated with the transformation toughening in the 3Y-TZP material, while retaining high strength.

In a population-based sample of British women aged over 70 years old, lean mass and peak lower limb muscle force were both independently associated with hip strength and fracture risk indices, thereby suggesting a potential benefit of promoting leg muscle strengthening exercise for the prevention of hip fractures in postmenopausal women.
Introduction: To investigate cross-sectional associations of lean mass and physical performance, including lower limb muscle function, with hip strength, geometry and fracture risk indices (FRIs) in postmenopausal women.

Background: Our objective was to analyze the effect of different anteromedial coronoid fracture patterns with different combinations of ligamentous repairs. We hypothesized that smaller fractures would be sufficiently treated with ligamentous repair alone but that larger fragments would require a combination of ligament and bony repair versus reconstruction.

Background: Total elbow arthroplasty (TEA) and open reduction-internal fixation (ORIF) are 2 viable surgical treatment options for acute, intra-articular distal humeral fractures in elderly patients. Whereas recent systematic reviews and randomized trials have suggested that TEA and ORIF result in similar functional outcome scores, no previous study has assessed the comparative cost-effectiveness between TEA and distal humeral ORIF in this specific demographic.
Methods: A Markov model was created with the highest-level data available from the literature depicting transitioning health states based on treatment strategies. Read More

Bone is a complex material comprising high stiffness, but brittle, crystalline bio-apatite combined with compliant, but tough, collagen fibres. It can accommodate significant deformation, and the bone microstructure inhibits crack propagation such that micro-cracks can be quickly repaired. Catastrophic failure (bone fracture) is a major cause of morbidity, particularly in aging populations, either through a succession of small fractures or because a traumatic event is sufficiently large to overcome the individual crack blunting/shielding mechanisms.

In addition to cardiomyopathy and nephropathy, diabetics are at higher risk of mortality and morbidity due to greater risk of bone fractures and skeletal abnormalities. Patients with diabetes mellitus have lower bone quality in comparison to their non-diabetic counterparts mainly because of hyperglycemia, toxic effects of advanced glycosylation end-products (AGEs) on bone tissue, and impaired bone microvascular system.

Ultra-thin porous polyethylene has been widely preferred in orbital blow out fracture repair for many years as a safe and stable material. Delayed complications related to the implant in orbital blow out fracture repair are very rare and usually begin as a periorbital inflammation. Infections and tissue reaction to the foreign body are regarded as main causes for implant-related inflammation of which symptoms may vary among the patients and may involve subacute and chronic eyelid swelling, skin redness, pain, conjunctival injection, proptosis, and acute orbital inflammation.

They can also be responsible for osteoarticular symptoms (pain, joint stiffness, deformity or fracture) and will require a clinical, radiological and a histopathological assessment. Depending on the lesion, the management may consist of observation or a complex surgical procedure that will take place after a multidisciplinary discussion including the radiologist, the pathologist and the orthopaedic surgeon.
