A new, low cost, locking plate for the long-term fixation of a critical size bone defect in the ratfemur: in vivo performance, biomechanical and finite element analysis.

Background: The optimum fixation device for the critical size bone defect is not established yet.

Objective: A reliable, feasible and low-cost fixation device for the long-term maintenance of a critical bone defect.

Methods: A custom-made plate made of poly-methyl-methacrylate was used for the fixation of a critical defect of rats' femurs.

Flow cytometry as a diagnostic tool for identifying total hip arthroplasty loosening and differentiating between septic and aseptic cases.

Purpose: Implant loosening represents one of the major factors of total hip arthroplasty (THA) failure. The purpose of this study was to identify specific markers indicative of septic and aseptic loosening in patients that underwent THA.

Methods: Flow cytometry was performed in blood samples of 20 patients with loosening (10 septic/10 aseptic).

Management of proximal interphalangeal joint hyperextension injuries: a randomized controlled trial.

Purpose: To compare the effectiveness of buddy strapping and aluminum orthosis for treatment of proximal interphalangeal (PIP) joint hyperextension injuries. We also evaluated the effect of age on the outcome by comparing our results in adults and children.

Methods: One hundred twenty-one consecutive patients with a PIP joint hyperextension injury of the index, middle, ring, or little finger and without fracture were evaluated.

Comparison of early mobilization protocols in radial head fractures.

Objectives: We compared 2 different protocols of early mobilization with a protocol of delayed mobilization in patients with simple radial head fractures (B2.1 type of Orthopaedic Trauma Association Classification). An attempt to correlate certain characteristics of the radial head fractures with outcome was made.

Bifocal pyomyositis in a 3-year-old child with eczema: a case report.

Pyomyositis is an infection of the skeletal muscles, resulting in a pus-filled abscess. Immunodeficiency of the patient is considered to play an important role in pathogenesis. We report a case of a 3-year-old child, who presented with multifocal pyomyositis in the gastrocnemius muscle, extending to the posterior muscles of the thigh.

Comparative study of surgical treatment of ulnar nerve compression at the elbow.

Hypothesis: The optimal surgical treatment for cubital tunnel syndrome remains unclear. We aim to evaluate the long-term outcome of surgical treatment by comparing the results of the different methods proposed.

Materials And Methods: We retrospectively reviewed 113 patients in whom 3 different surgical methods were used for cubital tunnel syndrome treatment.

The role of erythropoietin in central and peripheral nerve injury.

Erythropoietin (Epo) is a cytokine which controls red cell production. Apart from the red cell surface, erythropoietin's receptor (Epo-R) is also expressed in a large variety of normal tissues. Erythropoietin, as well as its receptor, is present in the central and peripheral nervous system.
