An implant removal tool for use in removing an expandable spinal implant device from a patient and a method of use. The tool includes a shaft having a distal end with a plurality of tabs and a central bore having a threaded section with an internal threaded wall. The plurality of tabs may include two curved tabs having blunt distal ends for cooperating with an implant. The threaded section is configured to receive a threaded shaft of an implant and lock the implant thereon for removal.

An embodiment includes an orthopedic fusion system comprising: a cage; a curved first channel coupling a lateral wall of the cage to a superior surface of the cage; a curved second channel coupling the lateral wall of the cage to an inferior surface of the cage; a third channel coupling the superior surface of the cage to the inferior surface of the cage; a curved first anchor configured to slide within the first channel; a curved second anchor configured to slide within the second channel; and a resilient member comprising a resilient first arm that projects across a portion of the first channel and a resilient second arm that projects across a portion of the second channel. Other embodiments are described herein.

An apparatus for implanting a medical implant into bone includes: an implant having at least one predetermined natural frequency; and an instrument, comprising: a housing; a coupler carried by the housing and configured to be mechanically connected to a medical implant; and a forcing mechanism carried by the housing and operable to apply a cyclic excitation force at the predetermined natural frequency.

The present disclosure pertains to ankle prostheses. In an example embodiment, the ankle prosthesis comprises an adjustable and replaceable intermediate implant that is disposed between a tibial implant and a talar implant. The intermediate implant is adjustable relative to the tibial implant and can be interlocked therewith once adjusted. Methods of using, fitting, and adjusting the device are also described. Still other embodiments are described.

A hand manipulated endoscopic medical device includes a body having a proximal end, which is hand manipulated, a distal end which includes a manipulator, a light emitting device at the distal end, an imaging device at the distal end. A tool for extracting an artificial lumbar disc from between a pair of vertebral plates includes a handle, a member for transmitting force, and a sharpened end, specially configured to be placed between the artificial disc and the vertebral plate. A tool for implanting or explanting a ball to or from an artificial lumbar disc includes a pinion shaft and a pinion shaft enclosure, with a tightening knob at the proximal end of the shaft enclosure and coupled to the pinion shaft, a pinion at the distal end of the pinion shaft, a grappling device at the pinion, and a pair of semi-circular rings.

The present application is directed a Joint Revision Surgery Apparatus which includes a surgical knife blade guide block which has a plurality of rearward blade guide slots, a central cavity and a plurality of guide slots having a two-way adjustable L-shaped guide plate. The surgical knife blade guide block central cavity houses a stem trunnion securing member and is positioned over the trunnion end of the existing prosthesis to be removed and secured to the prothesis. The guide blade block is secured to the trunnion of the prosthesis to be extracted using a stem trunnion securing member housed within the guide block. Straight, curved and compound curved knife blades are guided by the blade guide slots to cut the prothesis free. The Joint Revision Surgery Apparatus facilitates rapid, efficient and complete removal of an existing prosthesis during joint revision surgery, and significantly increases positive medical outcomes for joint revision procedures.

The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.
