Description
Background: A new growing rod design, the semi-constrained growing rod (SCGR), with the added advantage of axial rotation freedom within the components, has been introduced at our centre which has been shown to be growth friendly. We hypothesize that the SCGR system would reduce autofusion in vivo, thereby maximising the coronal plane correction, T1-S1 growth and the final correction achieved at definitive fusion for children with early onset scoliosis. Methods: 28 patients had either single or dual 5.5mm diameter SCGR placed minimally invasively through a submuscular approach. Surgical lengthening procedures occurred approximately every six months until the definitive fusion procedure was performed for 18 patients. Scoliosis, kyphosis and lordosis angles, T1-S1 trunk length and any complications encountered were evaluated. Results: For the full cohort, before GR insertion, the mean major curve angle was 72.4° (SD 18.8, range 45–120) and mean T1-S1 trunk length was 282 mm (SD 59, range 129-365) and at the latest follow-up (mean 6.9 years, SD 3.3, range 2.0 –13.0), 38.8º (SD 17.5, range 10-90) and 377 mm (SD 62, range 225-487) respectively. For the subset of 18 patients who have had their final instrumented fusion surgery, the definitive surgery procedure alone produced a correction of the major curve angle by mean 20.3° (SD 16.1, p<0.0001), and an increase in the T1-S1 trunk length of mean 31.7mm (SD 23.1, p<0.0001). There were 14 complications involving 11 of the 28 patients, giving rise to 5 unplanned surgical interventions and one case where GR treatment was abandoned. Conclusions: SCGR patients exhibited statistically significant increase in T1-S1 trunk length and statistically significant decrease in the severity of scoliosis over the course of GR treatment and again, importantly, with the definitive fusion surgery, suggesting that autofusion had been minimised during GR treatment with relatively low complication rates.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
