【 摘 要 】

Background

There has been no report regarding the results of two-level keyhole foraminotomy. The purpose of this study was to detail clinical outcomes following consecutive two-level cervical foraminotomy (tandem keyhole foraminotomy (TKF)) in patients with radiculopathy.

Methods

The authors conducted a retrospective review of 35 cases involving patients treated by a single surgeon using TKF. Clinical symptoms, data of physical examinations, pathology and clinical outcomes were detailed and discussed about this surgical method.

Results

Patients consisted of cervical disc herniation (CDH) (19/35), cervical spondylotic radiculopathy (CSR) (13/35), and cervical spondylotic amyotrophy (CSA) (3/35). TKF was performed from C3 to C5 in 2 patients (6%), from C4 to C6 in 7 patients (20%), from C5 to C7 in 23 patients (66%), and from C6 to T1 in 3 patients (8%). The mean operative duration was 99.2 min (range, 72 to 168 min). The mean estimated blood loss was 55.8 g (range, 0 to 200 g). Radicular pain was relieved within 3 months in 88% (29/32) and in 97% (31/32) at final follow-up. Resolution of muscle weakness was recognized within 6 months after operation in all CSA cases. Sixty-six percent of patients showed a greater than 20% deficit in grip weakness on the affected side compared with the normal side. After pain was relieved, grip strength improved by more than 15%.

Conclusions

TKF is a safe and highly effective procedure for patients with cervical radiculopathy and does not require invasive preoperative examinations. Further investigation is required to determine the effects of consecutive facetectomy.
