摘要： An odd angle internal fixation device for a transverse fracture located at the junction of the metaphysis and diaphysis of a long bone such as the proximal humerus. The internal fixation device includes an elongated lag screw and a rectangular shaped guide plate. The lag screw is introduced through the diaphyseal segment of the fracture at an angle ranging approximately between 155.degree. to 170.degree., cross fixing the bone fracture line and settling in the depth of the epiphysis. The guide plate serves as a guide for the lag screw and allows the engagement of the head of the screw to the inner wall of its short barrel. The engagement would cause the rectangular guide plate which is attached to the barrel, to be compressed against the diaphyseal cortex as the screw advances deeper into the epiphysis.

摘要： An axial loading apparatus for applying a continuous compressive force on top of a patient's head which is aligned with the top of the patient's head. The compressive force serves to strengthen the spine. The patient can direct how much force is applied and for how long the force is applied and as the patient's strength and resistance increase, the weights can be increased and the length of time can be increased. The axial loading apparatus comprises a frame member which has a base portion, a vertical portion affixed, and a top inclined portion connected to the vertical portion. The axial loading apparatus further comprises an actuator mechanism for actuating the load onto the patient's head, a locking mechanism for preventing undesirable loading, and a loading and holding mechanism for loading onto the patient's head.

摘要： The present invention is a novel and unique orthopedic apparatus for holding, maneuvering and maintaining a body part of a patient during orthopedic surgery. The orthopedic apparatus provides for assisting the primary surgeon during orthopedic surgery by holding, maneuvering and maintaining a patient's leg, thereby eliminating any assistant surgeon in the surgery operation. The orthopedic apparatus is capable of independently accomplishing transverse sliding, up-and-down tilting, lateral swinging, longitudinal extension/retraction, and axial rotation so that the surgeon can properly positioned a patient's leg for the orthopedic operation. The orthopedic apparatus has self-locking gear mechanisms to hold the various sections of the orthopedic apparatus in position to thereby hold the patient's leg in the proper position throughout the surgical operation. The orthopedic apparatus can be mechanically, electrically or hydraulically driven to adjust the orthopedic apparatus, so that the surgeon can position the patient's leg with great accuracy during surgery.

摘要： The present invention is an improved unique odd angle internal fixation device for both a transverse and longitudinal fracture located at the junction of the metaphysis and diaphysis of a long bone such as the proximal humerus. The improved odd angle internal fixation device includes an elongated lag screw and a rectangular shaped guide plate having multiple holes throughout the plate to host pins and screws and four tips on the front side of the plate. A lag screw with a cylindric head having a hexagonal cavity introduced through the diaphyseal segment of the fracture at three angles, 90, and 150 and 160 degrees, cross fixing the respective bone longitudinal and transverse fracture line and settling in the depth of the epiphysis. An additional locking screw is introduced on the top of the lag screw head to securely lock the lag screw after being settled into the epiphysis. The guide plate serves as a guide for the lag screw and allows the engagement of the head of the lag screw to the inner wall of its short barrel portion. The engagement would cause the guide plate which is attached to the barrel, to be compressed against the diaphyseal cortex as the lag screw advances deeper into the epiphysis at said three angles.
