Cruciate ligament reconstruction has progressed dramatically in the last 20 years. Anatomic placement of ligament substitutes has fostered rehabilitation efforts that stress immediate and full range of motion, immediate weightbearing, neuromuscular strength and coordination, and early return to athletic competition (3 months). This has placed extreme importance on secure graft fixation at the t...

Background and aims Using free quadriceps tendon graft for anterior cruciate ligament (ACL) reconstruction has become more popular in the last years due to the low morbidity at the harvest site and biomechanical and structural properties similar to other types of graft (hamstring and patellar tendons). As long as the tibial tunnel fixation with interference screws is considered the standard fix...

Bone regeneration is a complex, well-orchestrated physiological process of bone formation, which can be seen during normal fracture healing, and is involved in continuous remodelling throughout adult life. However, there are complex clinical conditions in which bone regeneration is required in large quantity, such as for skeletal reconstruction of large bone defects created by trauma, infection...

BACKGROUND Although three-dimensional (3D) β-tricalcium phosphate (β-TCP) scaffolds serve as promising bone graft substitutes for the segmental bone defect treatment, no consensus has been achieved regarding their optimal 3D architecture. METHODS In this study, we has systematically compared four types of β-TCP bone graft substitutes with different 3D architectures, including two types of por...

Restoration of mandible discontinuity defects continues as a challenge for maxillofacial surgeons. Despite the development of algorithms for reconstruction plates fixation and autogenous grafting techniques, complications are still encountered including screw loosening, bone resorption or delayed/incomplete union. The aim of the study was to analyze the possibility of obtaining bone union in th...

STUDY DESIGN An in vitro biomechanical investigation of the immediate stability in cervical reconstruction. OBJECTIVES The purpose of this study was to compare the segmental stability afforded by the interbody fusion cage, the anterior locking plate, and the "gold standard" autograft. SUMMARY OF BACKGROUND DATA Recently, interbody fusion cage devices have been developed and used for cervica...

OBJECTIVES/HYPOTHESIS This study attempts to characterize the biomechanical properties of a PDS-cartilage composite graft for use in septorhinoplasty. STUDY DESIGN Experimental Study. METHODS This study used a PDS analog, porcine cartilage cut to 1 × 5 × 20 mm, and a mechanical testing platform to measure flexure of a composite graft. Samples were assessed in four groups based on variations...
