Abstract
A surgical kit for minimally invasive total hip replacement includes a guide for inserting a guide wire into the body at the appropriate angle for reaming an Acetabulum. A shaft is inserted along the path of the guide wire. Working heads are sequentially attached to the shaft. The working heads of the reamers, impactors, trials and screw drivers are changed in the primary surgical incision thereby reducing the size of the incision and the trauma.
Claims10
A guide for use in orthopedic surgery to reduce surgical trauma comprising a leading end spaced from a trailing end, said leading end and said trailing end having a common longitudinal axis, an elongated handle connected at one end to said leading end and connected at the other end to said trailing end with an intermediate portion laterally displaced from said common longitudinal axis, said leading end and said trailing end each having a channel along said common longitudinal axis adapted to receive a guide wire and direct it along said common longitudinal axis.
A surgical kit for minimally invasive total hip replacement said kit comprising a guide having an elongated handle connected at one end to a leading end and connected at the other end to a trailing end, said leading end and said trailing end having a channel, a guide wire adapted to be received in said channel, at least one shaft having a connector on one end for attachment to a source of power and a connector on the other end for attachment to working heads, said working heads including a plurality of different sized reamers for the acetabulum, said reamers each having a connector for said shaft, a plurality of different sized trials for said acetabulum, said trials having a connector for said shaft, an impactor tool for impacting the acetabulum, said impactor tool having a connector for said shaft, and a screw driver for inserting bone screws, said screw driver having a connector for said shaft.
A method of minimally invasive hip replacement of a patient comprising the steps of
- (a) providing a guide having a leading end spaced apart from a trailing end, said leading end and said trailing end having a common longitudinal axis, said leading end and said trailing end having a channel along said common longitudinal axis, said leading end and said trailing end connected by a laterally displaced handle;
- (b) placing said leading end in contact within a surgical field with an exposed acetabulum of the patient;
- (c) manipulating said handle to ascertain the center of said acetabulum;
- (d) placing said trailing end in contact with the patient;
- (e) inserting a guide wire through said channel in said trailing end into said channel in said leading end of said guide;
- and
- (f) removing said guide from said guide wire.
