Magnetically controlled growing rods (MCGR) have been gaining popularity in the management of early-onset scoliosis (EOS) over the past decade. We present our experience with the first 44 MCGR consecutive cases treated at our institution. This is a retrospective review of consecutive cases of MCGR performed in our institution between 2012 and 2018. This cohort consisted of 44 children (25 females and 19 males), with a mean age of 7.9 years (3.7 to 13.6). There were 41 primary cases and three revisions from other rod systems. The majority (38 children) had dual rods. The group represents a mixed aetiology including idiopathic (20), neuromuscular (13), syndromic (9), and congenital (2). The mean follow-up was 4.1 years, with a minimum of two years. Nine children graduated to definitive fusion. We evaluated radiological parameters of deformity correction (Cobb angle), and spinal growth (T1-T12 and T1-S1 heights), as well as complications during the course of treatment.Aims
Methods
The use of serial casting in the management of early onset scoliosis (EOS) has been well described. Our aim was to evaluate outcomes of plaster jacket therapy in patients with EOS from a tertiary referral centre. A retrospective review of hospital records and PACS images of 27 patients to identify patients treated with serial casting over a five year period. The primary outcome measure was the need for surgical intervention, with change in Cobb angle used as a secondary outcome measure Mean age at presentation was 14 months (range 10 – 42), including 14 male and 13 female patients, with an average follow-up of 34 months. Curves were categorised according to aetiology: 16 idiopathic, 6 syndromic, 3 congenital and 2 neuromuscular curves. The mean Cobb angle at diagnosis was 43.7° (range 22 – 115) and mean rib vertebral angle difference (RVAD) was 22.2° (8 – 70). Duration of treatment was 9.9 months (range 3 – 27), with an average of two plaster jacket changes per child. At the time of review, patients fell into one of three groups. Group one (10 patients) failed conservative treatment due no improvement in Cobb angle (mean 48.4° compared with pre-op 53.9°, p value 0.55) and either had insertion of growing rods or had been listed for this procedure, at a mean age of 51.8 months. Group two (12 patients) had a mean Cobb angle of 38.9° pre-treatment which improved to 23.5° (p value <0.05) and were either treated in a brace or had discontinued treatment. The mean RVAD at initial diagnosis was 36.6° in group 1 compared with 13.8° in group 2 (p<0.05). All patients in group one requiring surgical treatment had an RVAD of greater than 20°. Serial casting is on-going for five patients (group three). Complications occurred in 30% of patients including pressure sores, chest infection and respiratory compromise requiring intubation. Current NICE guidance recognises that serial casting ‘rarely corrects scoliosis’ but recommends it may be used ‘to allow growth before a more permanent treatment is offered’. In our experience, serial casting did not allow any patients with a progressive scoliosis (determined by an RVAD of greater than 20°), to reach a single definitive fusion. However serial casting appeared to halt to curve progression until the child was suitable for the insertion of a growing rod system.
The study was designed to observe the patients emotional and physical response to total disc replacement surgery in the cervical spine. A prospective cohort study of patients undergoing Cervical total disc replacement (TDR) surgery at our institution. Surgery was carried for radicular and or axial neck pain. The Activ-C TDR (Aesculap) was used. Pre and post operative data was collected using validated questionnaires. 13 Consecutive patients from Nov 2007 to Aug 2008 were studied. All patients were planned for surgical intervention for symptomatic degenerative cervical disc disease at single or multiple levels. 7 male, 6 female. The Centre for Epidemiological Studies Depression Scale (CES-D) was used to assess the psychological impact. The Neck Disability Index (NDI) and a visual analogue scale (VAS) were used to assess the physical impact of the surgery. NDI shows a significant improvement at 6 and 12 months (p= 0.002 and p=0.02 respectively). The VAS also shows significant improvement at 6 and 12 months (p=0.004 and 0.008 respectively) The CES-D improved but failed to show any significant improvement at either interval. In our patient population surgical intervention with TDR for degenerative disc disease offers significant physical benefit over the short term. This does not correlate with an improvement in their emotional state.
