- Study Design. Cross-sectional study. Objective. To investigate the presence and magnitude of anterior spinal overgrowth in neuromuscular scoliosis and compare this with the same measurements in idiopathic scoliosis and healthy spines. Summary of Background Data. Anterior spinal overgrowth has been described as a potential driver for the onset and progression of adolescent idiopathic scoliosis (AIS). Whether this anterior overgrowth is specific for AIS or also present in nonidiopathic scoliosis has not been reported. Methods. Supine computed tomography (CT) scans of thirty AIS patients (thoracic Cobb 21-81 degrees), thirty neuromuscular (NM) scoliotic patients (thoracic Cobb 19-101 degrees) and 30 nonscoliotic controls were used. The difference in length in per cents between the anterior and posterior side {[(Delta A-P)/P] * 100%, abbreviated to A-P%} of each vertebral body and intervertebral disc, and between the anterior side of the spine and the spinal canal (A-C%) were determined. Results. The A-P% of the thoracic curves did not differ between the AIS (+1.2 perpendicular to 2.2%) and NM patients (+0.9 +/- 4.1%, P = 0.663), both did differ, however, from the same measurements in controls (-3.0 +/- 1.6%; Pamp;lt; 0.001) and correlated linearly with the Cobb angle (AIS r = 0.678, NM r = 0.687). Additional anterior length was caused by anterior elongation of the discs (AIS: A-P% disc +17.5 +/- 12.7% vs. A-P% body - 2.5 +/- 2.6%; Pamp;lt; 0.001, NM: A-P% disc + 19.1 +/- 18.0% vs. A-P% body -3.5 +/- 5.1%; Pamp;lt; 0.001). The A-C% T1-S1 in AIS and NM patients were similar (+ 7.9 +/- 1.8% and + 8.7 +/- 4.0%, P = 0.273), but differed from the controls (+4.2 +/- 3.3%; Pamp;lt; 0.001). Conclusion. So called anterior overgrowth has been postulated as a possible cause for idiopathic scoliosis, but apparently it occurs in scoliosis with a known origin as well. This suggests that it is part of a more generalized scoliotic mechanism, rather than its cause. The fact that the intervertebral discs contribute more to this increased anterior length than the vertebral bodies suggests an adaptation to altered loading, rather than a primary growth disturbance.

- OBJECTIVE The aim of this study was to evaluate the 5- to 8-year outcome of anterior cervical decompression and fusion (ACDF) combined with a structured physiotherapy program as compared with that following the same physiotherapy program alone in patients with cervical radiculopathy. No previous prospective randomized studies with a follow-up of more than 2 years have compared outcomes of surgical versus nonsurgical intervention for cervical radiculopathy. METHODS Fifty-nine patients were randomized to ACDF surgery with postoperative physiotherapy (30 patients) or to structured physiotherapy alone (29 patients). The physiotherapy program included general and specific exercises as well as pain coping strategies. Outcome measures included neck disability (Neck Disability Index [NDI]), neck and arm pain intensity (visual analog scale [VAS]), health state (EQ-5D questionnaire), and a patient global assessment. Patients were followed up for 5-8 years. RESULTS After 5-8 years, the NDI was reduced by a mean score% of 21 (95% CI 14-28) in the surgical group and 11% (95% CI 4%-18%) in the nonsurgical group (p = 0.03). Neck pain was reduced by a mean score of 39 mm (95% CI 26-53 mm) compared with 19 mm (95% CI 7-30 mm; p = 0.01), and arm pain was reduced by a mean score of 33 mm (95% CI 18-49 mm) compared with 19 mm (95% CI 7-32 mm; p = 0.1), respectively. The EQ-5D had a mean respective increase of 0.29 (95% CI 0.13-0.45) compared with 0.14 (95% CI 0.01-0.27; p = 0.12). Ninety-three percent of patients in the surgical group rated their symptoms as "better" or "much better" compared with 62% in the nonsurgical group (p = 0.005). Both treatment groups experienced significant improvement over baseline for all outcome measures. CONCLUSIONS In this prospective randomized study of 5- to 8-year outcomes of surgical versus nonsurgical treatment in patients with cervical radiculopathy, ACDF combined with physiotherapy reduced neck disability and neck pain more effectively than physiotherapy alone. Self-rating by patients as regards treatment outcome was also superior in the surgery group. No significant differences were seen between the 2 patient groups as regards arm pain and health outcome.

- STUDY DESIGN.: Prospective randomized controlled trial. OBJECTIVE.: To study the outcome of anterior cervical decompression and fusion combined with a structured physiotherapy program compared with the same physiotherapy program alone for patients with cervical radiculopathy. SUMMARY OF BACKGROUND DATA.: Knowledge concerning the effects of interventions for patients with cervical radiculopathy is scarce due to a lack of randomized studies. METHODS.: Sixty-three patients were randomized to surgery with postoperative physiotherapy (n = 31) or physiotherapy alone (n = 32). The surgical group was treated with anterior cervical decompression and fusion. The physiotherapy program included general/specific exercises and pain-coping strategies. The outcome measures were disability (Neck Disability Index), neck and arm pain intensity (visual analogue scale), and the patient's global assessment. Patients were followed for 24 months. RESULTS.: The result from the repeated-measures analysis of variance showed no significant between-group difference for Neck Disability Index (P = 0.23). For neck pain intensity, the repeated-measures analysis of variance showed a significant between-group difference during the study period in favor of the surgical group (P = 0.039). For arm pain intensity, no significant between-group differences were found according to the repeated-measures analysis of variance (P = 0.580). Eighty-seven percent of the patients in the surgical group rated their symptoms as "better/much better" at the 12-month follow-up compared with 62% in the nonsurgical group (P < 0.05). At 24 months, the corresponding figures were 81% and 69% (P = 0.28). The difference was significant only at the 12-month follow-up in favor of the surgical group. Significant reduction in Neck Disability Index, neck pain, and arm pain compared with baseline was seen in both groups (P < 0.001). CONCLUSION.: In this prospective, randomized study of patients with cervical radiculopathy, it was shown that surgery with physiotherapy resulted in a more rapid improvement during the first postoperative year, with significantly greater improvement in neck pain and the patient's global assessment than physiotherapy alone, but the differences between the groups decreased after 2 years. Structured physiotherapy should be tried before surgery is chosen. Copyright © 2013 Lippincott Williams & Wilkins. Unauthorized reproduction of this article is prohibited.
