OBJECTIVE: To investigate the clinical effectiveness of cervical arthroplasty with Mobi-C prosthesis for treatment of cervical spondylotic radiculopathy. METHODS: From March 2008 to November 2009, a group of 67 patients with cervical spondylotic radiculopathy were analyzed retrospectively. The short form-36 physical component summary (SF-36) and visual analogue scale (VAS) score were used to compare clinical outcome pre- and postoperatively. The follow-up was performed at 3 d, 3 months, 6 months and 1 year postoperatively. Static and dynamic radiography were taken to evaluate height of disc space, range of motion (ROM) and heterotopic ossification (HO) of index levels. RESULTS: Fifty-one cases were followed up, 16 cases were lost. Average follow-up was for 19.7 months (13 – 31 months). All of patients had improvement for clinical symptoms. There was a significant difference on SF-36 between pre- and postoperatively. The significant difference was found in VAS score in which neck pain was decreased from preoperative 4.6 +/- 0.4 to postoperative 2.0 +/- 0.5 (P < 0.05), arm pain was decreased from preoperative 6.5 +/- 0.4 to postoperative 1.3 +/- 0.4 (P < 0.05). There was a significant difference in height of disc space which was increased from preoperative (6.5 +/- 1.1) mm to (7.7 +/- 0.9) mm (P < 0.05). ROM was increased from preoperative 7.2 degrees +/- 3.1 degrees to latest follow-up 8.1 degrees +/- 3.2 degrees , however, no significant difference was found concerning ROM pre- and postoperatively (P > 0.05). No other complications were met during follow-up period other than the 17 cases of heterotopic ossification in ClassI, the 7 cases in Class II in 1 year postoperatively, but no any correlation were found between the radiographic finding in HO and clinical symptoms. CONCLUSIONS: Cervical arthroplasty with Mobi-C could improve neurofunctional symptoms, maintain ROM of index level and height of disc space. For accurate patient selection, long term follow-up is still needed in prospective randomized study
