摘要： A total hip joint prosthesis has a ball, replacing the ball of the hip joint ball and socket, affixed to the femur by a stem. Stem stress is reduced by providing a rounded cross-section of the stem truncated along the lateral side in the critical section subject to greatest cyclic loading. The stem is of controlled low flexibility so that when the bone cement and stem composite structure is in place, the bone is subject to a maximum percent of normal stress from bending moments. By virtue of the truncated shape and its size relative to the bone cavity, stress in the stem is minimized when the stem alone carries the load.

摘要： The shank blade widens conically to all sides from a distal end to a point between 2/3 and 3/4 of the height of the shank. The upper portion of the blade is thinner and tapers to the collar. The shank avoids the so called "closure (final rotation" which is caused by too small a space for the shank blade in the neck of a femur bone. The shank blade has a generally rectangular cross-section with rounded corners to fit against the cortical bone tissue and has a trochanter wing to improve transmission of torque from the surrounding musculature to the hip joint.
摘要翻译：柄刀片从远端到柄部的高度的2/3和3/4之间的点的锥面几何角度变宽。刀片的上部较薄，并向颈圈逐渐变细。柄部避免了所谓的“关闭（最终旋转”），这是由于股骨头颈部的柄刀片的空间太小造成的。柄刀片具有大致矩形的横截面，具有圆角以适合皮质骨组织，并具有转子翼，以改善从周围肌肉组织到髋关节的扭矩传递。

摘要： A prosthetic socket 1 is made in a generally crescent shape with an outer cylindrical surface and includes horns 5, 6 which may be contracted, in order to allow it to be introduced, in the manner of a clip, in a cylindrical osseous cavity, where it is held by elasticity, without any cementing. The anchorage of this type of prosthesis is made directly onto the bone, using materials with a Young's modulus very close to the Young's modulus of the spongiosa tissue of the pelvis guarantees longevity of the anchorage, which is protected from loosening which may occur when cements of the methyl methacrylate type or others are used, such as metal or ceramic materials designed to be self-fixing, but of which the Young's modulus is sufficiently different from the Young's modulus of the bone that mechanical stresses may occur causing loosening. The invention also relates to an artificial head of a femur of three part construction.

摘要： Endoprosthetic metacarpal phalangeal joint devices are well known in various forms including unitary flexible structures for connection between the bones, and others with separate phalangeal and metacarpal components for respective bone connection and inter-engagement or connection for mutual articulation in a hinge action. All such devices are applied individually to respective joints and can tend to fail due to conditions leading to ulnar drift. It is now proposed that this tendency be obviated by mechanically interconnecting a plurality of devices of the latter form in the hand, suitably by use of a common hinge pin. The pin preferably has slight longitudinal curvature to pass through the natural joint centers. The phalangeal components preferably each have a socket for bone connection and a stem for axle connection, the stem being slidably and rotatably received in the socket to accomodate torsional loading.

摘要： There is disclosed a prosthesis comprising a prosthetic element and a polymethylmethacrylate film fixedly adhered thereto. The prosthesis comprises a surface adapted to be fixedly attached to bone and bears a polymethylmethacrylate film upon the attachment surface. The polymethylmethacrylate film is adhered to the prosthetic element by a process which comprises treating the prosthetic element surface to eliminate any weak boundary layer, applying polymethylmethacrylate to the treated surface, and thereafter annealing the polymethylmethacrylate film.

摘要： The knee pivot or hinge shaft of the artificial limb connecting the upper limb portion and the lower portion is located forward of the center line of gravity in the prosthesis whereby the arc of the foot of the limb is shortened as the foot moves rearwardly from a straightened position of the limb. The knee joint is provided with a locking mechanism which is actuated to lock the upper limb portion to the lower limb portion either by downward pressure applied to the upper limb portion as the artificial limb rests on a support surface or by pressure applied to the heel portion of the foot as it engages a support surface. The actuating lever of the locking mechanism pivots about a first fulcrum to actuate the locking mechanism as pressure is initially applied to the heel of the foot during the amputees stride and, as the weight of the amputee is transferred from the heel to the ball or toe portion of the foot, the actuating lever pivots about a second fulcrum. The locking mechanism remains in the actuated or locked condition as the lock actuating lever moves from one fulcrum to the other.

摘要： An artificial leg of the kind in which the shin portion and the knee portion are shaped from a block of wood or similar solid material, has the knee and shin portions connected by pairs of front and rear links, the effective length of the front links being less than that of the rear links and the connections between the links and the knee and shin portions being positioned so as to form an articulation of which the instantaneous center of rotation lies upon an ascending curve for a predetermined angle of relative rotation between the two portions of the leg from the fully extended position. The resultant joint provides a stable weight support until it has been flexed through the predetermined angle and is thereafter capable of flexure through more than a right angle.
