INTRA-ARTICULAR AND PERI-ARTICULAR FRACTURES OF THE PHALANGES [PDF]
The Journal of Bone and Joint Surgery. British volume, 1963 1. A review of intra-articular and peri-articular fractures of the phalanges has been carried out, and the late results of such injuries have been examined. 2. These fractures usually unite by bone. 3. The results of conservative treatment by immobilisation are satisfactory in the case of mallet fractures, hyperextension sprain fractures and ...

Healing of articular cartilage in intra-articular fractures in rabbits.
The Journal of Bone & Joint Surgery, 1980Intra-articular fractures were created in the distal end of the femur in adult rabbits. Fractures were then reduced in three different fashions: incomplete reduction, adequate reduction without compression of the fregments, and ideal reduction, which consisted of reduction with strong compression of the fracture fragments.

Fatigue of Articular Cartilage
Nature, 1973IT has been suggested1 that fibrillation, the earliest change in osteoarthritic cartilage visible to the naked eye, may be the result of fatigue failure. Abnormally high stresses in the superficial layer of cartilage could be produced by unusually high applied loads, incongruity of the joint surface, or softening of the cartilage by mucopolysaccharide ...

The Microhardness of Articular Cartilage
Clinical Orthopaedics and Related Research, 1975The standard metallurgical technique of microhardness testing was useful for investigations on the physical properties of articular cartilage. The problem of visco-elasticity of the cartilage was overcome by using a brittle lacquer coating as a memory device. The surface layer was the hardest plane when the superficial layer was intact.

Fracture of Articular Cartilage
Journal of Biomechanical Engineering, 1996Crack formation and propagation is a significant element of the degeneration process in articular cartilage. In order to understand this process, and separate the relative importance of structural overload and material failure, methods for measuring the fracture toughness of cartilage are needed.

The articular disc of the hand [PDF]
Cells Tissues Organs, 1975 The carpal articular disc has been studied in serial sectioned embryonal and fetal hands. It can be concluded that the articular disc is an extensive fibrous system that comes from the ulnar edge of the distal end of the radius and reaches, bordered by the deep layer of the antebrachial fascia, the base of metacarpal V.

Articular cartilage transplantation
Human Pathology, 1977This report describes the biopsy findings in four of 30 patients treated with cadaver osteochondral shell allografts for osteoarthritis in the knee. This study demonstrates that graft cartilage cells can survive in excess of 25 months, and that host bone can completely replace graft bone by creeping substitution.

The morphologic changes of articular cartilage with bone grafting to fill subchondral bone defects were studied in 23-month-old New Zealand rabbits with bilateral tibial subchondral bone defects. The defects were made approximately 5 mm below the articular surface and were covered with surrounding tissues. The right side was filled with calcium sulfate

The acute and repetitive impact and torsional joint loading that occurs during participation in sports can damage articular surfaces causing pain, joint dysfunction, and effusions. In some instances, this articular surface damage leads to progressive joint degeneration. Three classes of chondral and osteochondral injuries can be identified based on the

The collagens of articular cartilage
Seminars in Arthritis and Rheumatism, 1991Articular cartilage contains at least five genetically distinct types of collagen. Types II, IX, and XI are cartilage-specific and are cross-linked together in a copolymeric network that forms the extracellular framework of the tissue. Fibrils of type II collagen provide the basic architecture.
