'Life-changing surgery': English-language news media representation of selective dorsal rhizotomy

Selective dorsal rhizotomy in non-ambulant children with cerebral palsy: a multi-center prospective study

PURPOSE

Assess the effects of selective dorsal rhizotomy (SDR) on motor function and quality of life in children with a Gross Motor Function Classification System (GMFCS) level of IV or V (non-ambulatory).

METHODS

This is a prospective, observational study in three tertiary neurosurgery units in England, UK, performing SDR on children aged 3-18 with spastic diplegic cerebral palsy, and a GMFCS level of IV or V, between 2012 and 2019. The primary outcome measure was the change in the 66-item Gross Motor Function Measure (GMFM-66) from baseline to 24 months after SDR, using a linear mixed effects model. Secondary outcomes included spasticity, bladder function, quality of life, and pain scores.

RESULTS

Between 2012 and 2019, 144 children who satisfied these inclusion criteria underwent SDR. The mean age was 8.2 years. Fifty-two percent were female. Mean GMFM-66 score was available in 77 patients (53.5%) and in 39 patients (27.1%) at 24 months after SDR. The mean increase between baseline and 24 months post-SDR was 2.4 units (95% CI 1.7-3.1, p < 0.001, annual change 1.2 units). Of the 67 patients with a GMFM-66 measurement available, a documented increase in gross motor function was seen in 77.6% (n = 52). Of 101 patients with spasticity data available, mean Ashworth scale decreased after surgery (2.74 to 0.30). Of patients' pain scores, 60.7% (n = 34) improved, and 96.4% (n = 56) of patients' pain scores remained the same or improved. Bladder function improved in 30.9% of patients.

CONCLUSIONS

SDR improved gross motor function and reduced pain in most patients at 24 months after surgery, although the improvement is less pronounced than in children with GMFCS levels II and III. SDR should be considered in non-ambulant patients.

'Wanting no regrets': Parental decision making around selective dorsal rhizotomy

BACKGROUND

Selective dorsal rhizotomy (SDR) is an irreversible neurosurgical procedure used to reduce spasticity while aiming to improve gross motor function for children with cerebral palsy (CP). Little research has explored the complexity of parental decision-making experiences surrounding SDR surgery and required rehabilitation. The aim was to explore parental experiences and expectation in the decision-making process around the SDR operation, physiotherapy treatment and outcomes.

METHOD

Qualitative methods using in-depth, semi-structured interviews were used. Eighteen parents (11 mothers and 7 fathers) participated whose child had SDR and completed 2-year post-operative rehabilitation. Data were analysed using thematic analysis.

RESULTS

Decision making involved an interacting process between the 'parental information seeking experience', 'influence of professional encounters and relationships' and 'emotional and social aspects'. Despite underlying uncertainties about outcomes, parental drivers of expectations and aspirations for their child preceded and sustained this decision-making process. A foundational narrative of 'wanting no regrets' resolved their decision to undertake SDR. Outcomes did not always match expectations, and parents moved away from a position of idealism, which was driven in part by parental information seeking including overly optimistic media representation.

CONCLUSION

Universally, parents expressed they had 'no regrets' on their decision, yet many felt a mismatch between expectation and outcomes of SDR surgery. A greater understanding of the complex nature of SDR decision making is required to help improve family preparedness and provide support from clinicians to enable balanced discussions in parental decision-making.
