Use of a Costal Osteochondral Graft for Reconstruction of a Proximal Phalanx Head with a Comminuted Fracture of the Proximal Interphalangeal Joint.

We report the use of costal osteochondral grafting with a pins and rubbers traction system (PRTS) for treatment of a complex cartilage defect of the proximal interphalangeal (PIP) joint in a 41-year-old male carpenter who had inadvertently incompletely severed his finger with a power saw. The skin laceration extended to the dorsal aspect of his ring finger and resulted in incomplete loss of the ulnar condyle and comminution of the radial condyle of the proximal phalanx of the PIP joint. The diagnosis was intra-articular PIP joint open fracture of the left ring finger with a 60% defect of the proximal phalanx joint surface.

Objective Colorimetric Evaluation of Aging-related Articular Cartilage Degeneration.

Background: Aging is a primary risk factor for the development of osteoarthritis (OA). Recently, advanced glycation end products (AGEs) have received much attention in relation to aging and OA. Some AGEs are reported to be brownish, but the association between AGE levels and browning in articular cartilage is unknown.

Irreducible Elbow Fracture and Dislocation due to Incarceration of the Medial Epicondyle of the Humerus in a Child.

Medial epicondyle fractures of the humerus account for 11%-20% of all elbow injuries in children. Although intra-articular incarceration of the medial epicondyle occurs in 5%-18% of medial epicondyle fractures associated with an elbow dislocation, the mechanism of intrusion of the fracture fragment is unknown. We report a case of an irreducible elbow fracture and dislocation due to incarceration of the medial epicondyle fragment of the humerus, classified as a Watson-Jones type 3 fracture of the medial epicondyle, and present the mechanism of the intra-articular incarceration of the medial epicondyle fragment.

Treatment for Trochanteric Fracture of the Femur with Short Femoral Nail: A Comparison between the Asian Intramedullary Hip Screw (IMHS) and the Conventional IMHS.

Introduction: We usually use short femoral nails for the treatment of trochanteric fracture of the femur. In this retrospective study, we investigated and compared the clinical results of the conventional intramedullary hip screw (IMHS) and the Asian IMHS, which is a redesigned version of the former.

Materials And Methods: The subjects were 42 patients; 21 treated with the Asian IMHS and 21 were treated with the conventional IMHS.
