Surgery is advocated for cervical radiculopathy in patients who have intractable pain, progressive symptoms, or weakness that fails to improve with conservative therapy. Surgical indications for cervical spondylosis with myelopathy (CSM) remain somewhat controversial, but "most clinicians recommend operative therapy over conservative therapy for moderate-to-severe myelopathy" (Baron, M. E.). Physical therapy may be effective for restoring range of motion, flexibility and core strengthening. Decompressive therapies (i.e., manual mobilization, mechanical traction) may also help alleviate pain. However, physical therapy and osteopathy cannot "cure" the degeneration, and some people view that strong compliance with postural modification is necessary to realize maximum benefit from decompression, adjustments and flexibility rehabilitation. Surgery
Current surgical procedures used to treat spondylosis aim to alleviate the signs and symptoms of the disease by decreasing pressure in the spinal canal (decompression surgery) and/or by controlling spine movement (fusion surgery).Decompression surgery: The vertebral column can be operated on from both an anterior and posterior approach. The approach varies depending on the site and cause of root compression. Commonly, osteophytes and portions of intervertebral disc are removed.Fusion surgery: Performed when there is evidence of spinal instability or mal-alignment. Use of instrumentation (such as pedicle screws) in fusion surgeries varies across studies. See also

A supernumerary  kidney is an additional kidney to the number usually present in an organism. This often develops as the result of splitting of the nephrogenic blastema, or from separate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form separate capsulated kidneys; in some cases the separation of the reduplicated organ is incomplete (fused supernumerary kidney). Less than a hundred cases are known of one or two supernumerary kidneys. See also
