Total joint surgery involves the replacement of a "worn out" joint with an "artificial" joint. Surgical treatment usually includes removal of bone and replacement of the diseased joint with a metal, plastic, or ceramic implant. Joint replacement surgery may be necessary when badly damaged joints no longer move properly and cause severe pain.

Reamer spindle for minimally invasive joint surgery
ActiveUS20050216022A1Comfortable to useImprove comfortSurgical furnitureDiagnosticsSurgical approachLocking mechanism
An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and / or cleaning. Adjustment of the position of the handle about the spindle enables the palm / grip of each hand to be changed in order to provide maximum control in different orientations. The adjustment is desirable in order to accommodate operating on the left or right side of the patient, standing behind or in-front of the patient, or the use of a different surgical approach. Further, adjustment is important to accommodate the differing needs of surgeons who are naturally left or right handed.
