Comparison of three techniques for decellularization of porcine bone-tendon-bone grafts.

Anterior cruciate ligament injuries are frequent afflictions related to sports or physical trauma. Autograft reconstruction strategies cause secondary injury to the patient. One alternative, supported by clinical evidence, is porcine xenografts.

A comparison of three techniques for the osteosynthesis after minimal invasive osteotomies for hallux valgus.

Purpose: Third and fourth-generation minimal invasive osteotomies (MIO) for the treatment of hallux valgus (HV) have become popular procedures worldwide with promising results due to the improvement in the fixation method. The tricortical cannulated screw placement remains a complex procedure that is technically challenging and requires a long skill learning curve with high radiation exposure mainly in the form of intensifier shots (IS) required for the MIO fixation. This study aims to compare the number of X-ray IS required using three different techniques for the cannulated guide placement.

Preliminary tribological results of a new total temporary hip joint prosthesis spacer.

Temporary antibiotic-loaded cement spacers are widely used for treating chronic periprosthetic hip infections. The aim of this study is to evaluate the short-term tribological performance of ultra-high-molecular-weight polyethylene (UHMWPE) and (60Co) gamma-irradiated cross-linked UHMWPE (XLPE) self-mated systems as frictional pairs for temporary total hip spacers. A three-axial hip joint simulator, FIME II, was used to test the UHMWPE and XLPE self-mated systems under variable load profiles.

Anatomical variations of the sacro-iliac joint: a computed tomography study.

Purpose: To identify, describe, and compare the prevalence of sacroiliac joint anatomical variants.

Methods: A retrospective study was performed on computed tomography scans. Joint space was measured, and variants were classified as accessory joint, ileosacral complex, bipartite bony plate, semicircular defect, iliac bony plate, and ossification centers.

Anatomical variations of the acromial and coracoid process: clinical relevance.

Purpose: The acromial and coracoid process morphology is of clinical relevance due to associations with functional limitations and shoulder pathology. Our objective was to describe the anatomical characteristics of the acromial and coracoid process using computed tomography (CT).

Methods: Descriptive, observational, transversal and retrospective study.

Anatomy of foot Compartments: a systematic review.

Introduction: There are discrepancies regarding the anatomy of the foot which complicate standardizing foot compartment treatment. We synthesized the existing evidence regarding the compartmental anatomy of the foot MATERIALS AND METHODS: A systematic review was performed evaluating the anatomy of the foot compartments in non-pathologic specimens. The search strategy was performed in MEDLINE, Scopus, Web of Science, and EMBASE.

[Platelet-rich plasma in knee osteoarthritis treatment].

The biological changes that commonly cause degenerative articular cartilage injuries in the knee are primarily associated to misalignment of the joint and metabolic changes related to age, as occurs in osteoarthritis. Furthermore, the capacity for cartilage self-regeneration is quite limited due to the lack of vascularity of the tissue. To date there is no ideal treatment capable to stimulate cartilage regeneration; thus there is a need to seek alternative therapies for the treatment of such conditions.
