Injuries and Displacements of the Semilunar Cartilages.
Rotation strain, caused by twisting of the knee. If weight is being borne on the flexed knee with the foot firmly anchored to the ground, the force of the injury in addition to stretching or tearing the coronary ligaments may cause a split or fracture of the semilunar cartilage. When no weight is borne, or if the foot be not held, the semilunar may escape. The modern football boot, with good st...
متن کاملInjuries to the semilunar cartilages of the knee in miners.
Comprehensive records of 957 meniscectomies, over a period of 30 months, were obtained from five hospitals in one of the largest British coalfields. Corresponding records of 1,075 appendicectomies were collected and used as reference. The combined data provided conclusive evidence that the rate of meniscectomy was very much higher among miners than among other men. The proportions of bucket han...
متن کاملMechanism of derangements of the medial semilunar cartilage and their management.
The rotation element-The key to the function of the knee joint, and to its derangements, is the rotation of the tibia on the femur which occurs on flexion and extension movements. The knee is not a simple hinge joint. The opening and shutting of the front of the joint in the act of flexion and extension involves the tibia in a winding course set by the configuration of the medial condyle of the...
متن کاملImmunohistochemical characterization of the rabbit tracheal cartilages
The objective of this study was to immunohistochemically elucidate the major extracellular matrix constituents of rabbit tracheal cartilage. The impetus for this project is the need for crucial design and validation criteria for tissue engineering juxtaposed with the conspicuous lack of trachea extracellular matrix data in the literature. Tracheal tissue specimens were harvested from New Zealan...
متن کاملOn Parallel Generation of Partial Derangements, Derangements and Permutations
The concept of a partial derangement is introduced and a versatile representation of partial derangements is proposed with permutations and derangements as special cases. The representation is derived from a representation of permutations by iterative decomposition of symmetric permutation group Sn into cosets. New algorithms are proposed for generation of partial set derangements in t. The con...
