Acetabular drill pin

摘要

An acetabular drill pin comprising an elongated shaft having a proximal end and a distal end opposite thereof along a longitudinal axis of the shaft; at least two depth markings along the shaft, each of the at least two depth markings being positioned a pre-defined distance from the distal end of the shaft; and a fluted portion proximate the distal end of the shaft, the fluted portion being disposed between a shoulder and a flat-bottom milling tip, the tip being configured to penetrate a peri-acetabular area of a pelvis as the fluted portion is imparted with rotary motion.

1. A method for positioning an acetabular cup during a hip procedure, the method comprising the steps of: placing a first acetabular guide within an acetabulum; securing a drill sleeve to the first acetabular guide; providing two acetabular drill pins each comprising: an elongated shaft having a proximal end and a distal end opposite thereof along a longitudinal axis of the shaft; two depth markings positioned along the shaft a pre-defined distance from the distal end; and a fluted portion proximate the distal end of the shaft, the fluted portion being disposed between a shoulder and a flat-bottom milling tip configured to penetrate a peri-acetabular area of a pelvis; individually inserting the two acetabular drill pins into the peri-acetabular area of the pelvis through the drill sleeve; removing the drill sleeve and the first acetabular guide from the acetabulum while leaving the two acetabular drill pins inserted into the peri-acetabular area of the pelvis; advancing a second acetabular guide over the two acetabular drill pins; inserting an alignment pin into the second acetabular guide; and placing an acetabular cup into the acetabulum by positioning the long axis of a cup inserter substantially parallel to the alignment pin as the cup is placed into the acetabulum, wherein the step of individually inserting the two acetabular drill pins into the peri-acetabular area of the pelvis through the drill sleeve comprises drilling each of the acetabular drill pins into the peri-acetabular area of the pelvis until a top surface of the drill sleeve is positioned about half-way between the two depth markings of each acetabular drill pin.
