A pars defect is an absence of a bridge of bone that links the vertebra’s upper arm to its lower arm. A pars defect can be congenital. It can also be acquired as a result of trauma and it can also occur after surgery. A patient with a pars defect can at times have no symptoms. However, patients may also develop significant pain and instability with spondylolisthesis and nerve root compression due to the pars defect. Dr. Ghosh can provide surgical and nonsurgical solutions for patients with pars defects.
