Effects of electromagnetic fields on bone regeneration in experimental and clinical studies: a review of the literature.

Objective: To assess the experimental and clinical data regarding the effects of electromagnetic fields (EMFs) on fracture non-union.

Data Sources: The English language literature regarding EMFs on fracture non-union were searched using MEDLINE, Web of Science and Embase, for the period January 2006 to June 2011. The search terms were electromagnetic fields and non-union/bone marrow stem cells (BMSCs)/bone.

Mechanical properties of 7-10mm bone grafts and small slurry grafts in impaction bone grafting.

We compared the mechanical properties of morselized cancellous bone grafts of two sizes: 7-10 mm bone and small slurry bone (about 2 mm). The in vitro test was designed to simulate the hammer and impactor system for impaction bone grafting used in hip arthroplasty clinical practice. The 7-10 mm bone grafts showed higher height, elastic modulus, and massive extrusion strength than those of the small slurry bone grafts.

Selection of allografts for impaction bone grafting for bone defect reconstruction on the acetabular side.

Objective: To review the choices of allografts for bone defect reconstruction in acetabular revision surgery using the technique of impaction bone grafting.

Data Sources: The data cited in this review were mainly obtained from articles listed in PubMed that were published from January 1993 to July 2009. The search terms were "impaction bone grafting", "particle size", "mechanical property" and "biological behavior".

A preliminary report of patellofemoral arthroplasty in isolated patellofemoral arthritis.

Background: Isolated patellofemoral osteoarthritis is not uncommon. Surgical treatment of isolated patellofemoral arthritis remains controversial and poses a challenging treatment dilemma. The present study aimed to evaluate the short-term results of patellofemoral arthroplasty for patients with isolated patellofemoral osteoarthritis.
