RETRACTABLE OSTEOTOME. The EARP Interbody System is intended for intervertebral body fusion in the lumbar spine in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1 of the lumbosacral spine. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six months of non-operative treatment prior to treatment with an intervertebral cage. DDD patients may also have Grade 1 spondylolisthesis or retrolisthesis at involved levels. The device system must be used with supplemental fixation and autograft to facilitate fusion and is implanted via a posterolateral approach.
A chisel-like, one-piece manual surgical instrument designed to cut and/or shape bone by percussion during an orthopaedic procedure. It is hand-held by the operator who uses a surgical mallet or hammer to manually impart a force to the proximal end of the instrument. The distal end (the cutting or shaping edge) is sharp, often flat, but can be curved (concave) in design, and is typically bevelled on both sides with sloping curves. It is either entirely made of metal (e.g., high-grade stainless steel) or has a metal blade with a handle made of synthetic material (e.g., Tufnol). This is a reusable device.
