Selective dorsal rhizotomy in non-ambulant children with cerebral palsy: a multi-center prospective study. Childs Nerv Syst 2024; 40:171-180. [PMID: 37439914 PMCID: PMC10761507 DOI: 10.1007/s00381-023-06062-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 07/05/2023] [Indexed: 07/14/2023]
Abstract
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.

[PMID: 36828056 DOI: 10.1016/j.neuchi.2023.101425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 11/18/2022] [Accepted: 01/05/2023] [Indexed: 02/25/2023]
Abstract
PURPOSE The literature lacks a concise overview of complications secondary to selective dorsal rhizotomy (SDR). The aim of this study was to systematically review the literature regarding post-SDR complications, and to present them concisely. METHODS The protocol of the review was registered on Open Science Framework. Studies on SDR in cerebral palsy were included. The studies to be included used SDR for management of spasticity in patients with cerebral palsy. The long-term complications of SDR mentioned in the articles were inventoried. RESULTS Thirty studies were included for qualitative review. Twenty-one types of complication were identified. Structural complications were the commonest: scoliosis (214/1,043, 20.5%), hyperlordosis (101/552, 18.2%), spondylolysis (55/574, 9.5%) and kyphosis (67/797, 8.4%). Neurological complications comprised constipation (70/485, 14.4%), hip subluxation (3/29, 10.3%), spastic syndrome (4/47, 8.5%), sensory changes (106/1290, 8.2%) and urinary incontinence (61/1013, 6%). CONCLUSION This review should help surgeons and parents alike to know about the potential complications of SDR. Complications may affect quality of life and should be weighed. Although the majority of these complications were managed conservatively, there would still be a physical, psychological and financial burden which should be taken into account. Screening should be continued vigorously throughout skeletal growth and at reduced frequency thereafter, for timely intervention in case of structural complications.

Safety and Potential Efficacy of Selective Dorsal Rhizotomy in Adults with Spinal Cord Injury-Induced Spasticity: An Open-Label, Non-Randomized, Single-Arm Trial. World Neurosurg 2023; 170:e806-e816. [PMID: 36460198 DOI: 10.1016/j.wneu.2022.11.127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 11/26/2022] [Accepted: 11/28/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND Despite the abundant literature on the use of selective dorsal rhizotomy (SDR) in spastic cerebral palsy, no investigation has evaluated its use in adult patients with chronic spinal cord injury (SCI)-induced spasticity. The present investigation aimed to evaluate the safety and potential efficacy of SDR in chronic SCI-induced spasticity for the first time. METHODS In this open-label, single-arm, non-randomized clinical trial, all patients were assigned to the single study intervention arm and underwent SDR. The primary outcome measure was the safety profile of SDR. Secondary outcome measures were Modified Ashworth Scale, Penn Spasm Frequency Scale, visual analog scale for spasticity, Spinal Cord Injury Spasticity Tool, Spinal Cord Independence measure version III, and Short Form 36 Health Survey Questionnaire. RESULTS Six patients with cervical SCI and 4 with thoracic SCI were allocated to the single study intervention arm. No adverse event attributable to the SDR was found. Moreover, all secondary outcome measures of the study improved significantly over the study period (P < 0.001). Multiple regression analysis also found a significant association between level of injury and changes in average Modified Ashworth Scale scores (P = 0.041), Spinal Cord Injury Spasticity Tool score (P = 0.013), and Spinal Cord Independence measure version III total (P = 0.002) and mobility domain scores (P = 0.004) at 12-month postoperatively. CONCLUSIONS This clinical trial indicated that SDR is a safe and potentially effective procedure in patients with severe and intractable SCI-induced spasticity. However, future clinical trials with larger sample sizes and adequate power are required to validate our findings regarding efficacy.

Abstract
To investigate the urodynamic study (UDS) result in pediatric patients suffering from spastic cerebral palsy (CP). Medical records of patients diagnosed CP having pre-operative UDS results underwent selective dorsal rhizotomy (SDR) from Jan. 2020 to May. 2021 were retrospectively reviewed. Fifty-seven cases diagnosed spastic CP were included in the study (mean age, 6.73 ± 2.84 years), among which, 46 were ambulatory and 11 non-ambulatory. Average gross motor function measure-66 (GMFM-66) score was 62.16 ± 11.39. Reduced bladder capacity was seen in 49.12% of these cases and cases with lower GMFM-66 score possessed a higher incidence rate of having low bladder capacity (p < 0.01). Detrusor overactivity (DO) was shown in 33.33% of the patients. Cases with younger age presented a higher prevalence of DO (p < 0.05). Meanwhile, more non-ambulant patients suffered from DO (p < 0.05). Increased post-voiding residual (PVR) was seen in 21.05% of the cases. Those with higher average threshold in sphincter-associated input spinal nerve roots (rootlets) witnessed a higher rate of having abnormal PVR (p < 0.05). Abnormal UDS results were prevalent in pediatric patients suffering from CP. Motor function, age and threshold of their sphincter-associated spinal nerve roots laid corresponding effect on the abnormal UDS results.

Abstract
Background Selective dorsal rhizotomy (SDR) is one of the surgical alternatives for treating spasticity, especially in children with spastic diplegia secondary to cerebral palsy (CP). It is becoming increasingly used, and the results of this operation need to be further highlighted. Aim The main objective of this article was to present the results of such surgical procedure in a cohort of a specialized center, with a particular focus on a quantitative analysis (goniometry). Materials and Methods Retrospective review of the medical records and gait analyses of a cohort of 34 patients diagnosed with CP submitted to elective SDR at our institution, in a period of 6 years, was carried out. All patients underwent a thorough clinical and neurological assessment, gait analysis at a dedicated laboratory, and magnetic resonance imaging of whole neuro-axis. Statistical Analysis For continuous quantitative variables (goniometric angles and muscle tone), a t-student test was used. A scatterplot regression analysis was used for the comparison of modified Ashworth scale (mAS) scores and goniometry measurements. Results and Conclusion In a mean follow-up of 3.2 years, SDR provides a measurable and consistent improvement in the motor function of spastic patients, as per range of motion and tonus scales, with low complication rates. It also allows for patients to reduce their use of muscle relaxants, even though their global mobility does not change significantly. Therefore, it should be considered for CP patients who suffer with the deleterious effects of spasticity.

Abstract
BACKGROUND Selective dorsal rhizotomy (SDR) reduces spasticity in children with cerebral palsy (CP). We analyzed potential preoperative predictors of complications after SDR via single-level laminectomy at the conus medullaris. METHODS One hundred and forty SDRs performed in children (2-17 years) with CP were included in this retrospective study (March 2016 to July 2019). Of these children, 69% were ambulatory (Gross Motor Functional Classification System (GMFCS) II and III). Variables associated with wound dehiscence and infections, cerebrospinal fluid (CSF) leaks, and prolonged epidural pain management were analyzed statistically. RESULTS Five children (3.6%) showed prolonged wound healing, which was associated with obesity (BMI z-score ≥ 1.64; odds ratio (OR) 24.4; 95% confidence interval (CI) 3-199; p = 0.003). Two cases (1.4%) had superficial surgical site infections (SSIs), which was associated with obesity (p = 0.004) and thrombocytopenia (< 180,000 G/l; p = 0.028). The area under the curve at ≥ 1.55 BMI z-score for SSI was 0.97 (95% CI 0.93-0.99, p = 0.024), with a sensitivity and specificity for SSI of 100 and 94.9%, respectively. CSF leaks occurred in four (2.9%) children, associated with age ≤ 5 years (p = 0.029). Fifteen (10.7%) children required prolonged (4-5 days) epidural pain treatment, which was associated with non-ambulatory GMFCS levels (IV and V) (OR 3.6; 95% CI 1.2-10.8; p = 0.008). CONCLUSIONS SDR is safe for all GMFCS levels. Obesity predicts prolonged wound healing and SSI. Prolonged pain management via epidural pain catheter is safe, but care should be taken with non-ambulatory children.

Abstract
BACKGROUND Selective dorsal rhizotomy (SDR) for the management of lower extremity spasticity is a surgical technique that has existed since the 1900s. While much evidence supports its efficaciousness in reducing tone in the short term, limited information exists detailing the long-term outcome and evolution over time of patients undergoing SDR. METHODS All publications with 10 years or more of outcome data on patients undergoing SDR were identified from Medline and Embase databases using the search term "Rhizotmy." Only publications that were in English included patients with cerebral palsy under the age of 21 and discussed SDR for lower extremity spasticity were included. Case reports, reviews without primary data, or publications not accessible online were excluded from the review. RESULTS A total of 2128 publications were initially identified, of which 19 papers describing 1054 patients fit inclusion and exclusion criteria. GMFCS in most patients improved or remained stable over time after surgery, although durability of improvement and final outcome was dependent on initial functional status. Tone was noted to also substantially improve although a small proportion required additional oral or injectable pharmacologic agents and an even smaller proportion required baclofen pumps. Upper extremity function was also noted to improve substantially after SDR. A significant number of patients were independent for activities of daily living and were engaged in secondary education or gainful employment. A significant proportion of patients still required orthopedic surgery to the lower extremities after SDR, although the incidence of spinal deformity was not observed to be substantially elevated over that of natural history. CONCLUSION SDR offers substantial improvements to a number of domains beyond pure tone reduction. These changes are durable over time, although patient selection is crucial in identifying those patients that will have the most benefit. Long-term follow-up is in important in this population given the potential need for further interventions that still exist in many patients.

Abstract
AIM To evaluate the long-term effects of selective dorsal rhizotomy (SDR) 10 years or more after the procedure and complications observed any time after SDR in children with cerebral palsy (CP). METHOD Embase, PubMed, and the Cochrane Library were searched from their individual dates of inception through 1st June 2018 for full-text original articles in English that described long-term follow-up after SDR in children with CP. The authors independently screened publications to determine whether they met inclusion criteria; thereafter all authors extracted data on patient characteristics, the proportion of the original cohort being followed-up, and the reported outcomes. RESULTS Of the 199 studies identified, 16 were included in this evaluation: 14 were case series and two studies reported a retrospectively assigned comparison group. Evidence concerning function was limited by study design differences, clinical variability, loss to follow-up, and heterogeneity across trials. INTERPRETATION At 10 years or more follow-up, available studies generate low-level evidence with considerable bias. No functional improvement of SDR over routine therapy is documented. Furthermore, the long-term effects of SDR with respect to spasticity reduction is unclear, with many studies reporting a high amount of add-on spasticity treatment. More long-term follow-up using robust scientific protocols is required before it can be decided whether the use of SDR as routine therapy for children with CP is to be recommended or not. WHAT THIS PAPER ADDS Ten years after selective dorsal rhizotomy, available studies supply inconclusive evidence on functional outcomes. The long-term effect on spasticity is uncertain, studies reported a substantial need for add-on treatment. Short- and long-term complications seem frequent but are not reported in a consistent manner.

Abstract
OBJECTIVES Selective dorsal rhizotomy (SDR) is used to improve spasticity, gait, and pain in children with spastic diplegia. There is growing evidence supporting its long-term benefits in terms of functional outcomes, independence, and quality of life. There is, however, little contemporary work describing the surgical morbidity of this irreversible procedure. The purpose of this study is to evaluate the surgical outcomes and complications of SDR at a single United Kingdom center. METHODS Demographics, surgical, postoperative, and follow-up data for all patients undergoing SDR between 2011 and 2016 were collected from medical records. RESULTS Preoperative Gross Motor Function Classification System levels in 150 consecutive patients were II (35%), III (65%), and IV (1%). Median age was 6 years and 58% were male patients. There were no deaths, cerebrospinal fluid leaks, returns to theater, or readmissions within 30 days. There were no new motor or sphincter deficits. Postoperative neuropathic pain was reported by 5.3% and sensory symptoms by 8.7%. Other complications included: postoperative nausea and vomiting (19.3%), superficial wound infection (3.3%), urinary retention (1.3%), headache (6.7%), and urine or chest infection (4.7%). Follow-up data were available for all patients (93% to 12 months, 72% to 24 months). Persistent neuropathic symptoms were reported in 6.5% at 24 months. CONCLUSIONS SDR using a single-level approach is a safe procedure with low surgical morbidity. This study complements the growing evidence base in support of SDR for spastic diplegia and should help inform decisions when considering treatment options.

Selective dorsal rhizotomy for the treatment of severe spastic cerebral palsy: efficacy and therapeutic durability in GMFCS grade IV and V children. Acta Neurochir (Wien) 2018; 160:811-821. [PMID: 29116382 DOI: 10.1007/s00701-017-3349-z] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Accepted: 09/29/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Selective dorsal rhizotomy (SDR) has been established as an effective surgical treatment for spastic diplegia. The applicability of SDR to the full spectrum of spastic cerebral palsy and the durability of its therapeutic effects remain under investigation. There are currently limited data in the literature regarding efficacy and outcomes following SDR in Gross Motor Function Classification System (GMFCS) IV and V patients. Intrathecal baclofen has traditionally been the surgical treatment of choice for these patients. When utilised primarily as a treatment for the relief of spasticity, it is proposed that SDR represents a rational and effective treatment option for this patient group. We report our outcomes of SDR performed on children with severe cerebral palsy (GMFCS grade IV and V). The commensurate improvement in upper as well as lower limb spasticity is highlighted. Apparent benefit to urological function following SDR in this patient group is also discussed. METHOD A retrospective review of prospectively collected data for 54 paediatric patients with severe cerebral palsy (GMFCS IV-V) who received SDR plus specialised physiotherapy. Mean age was 10.2 years (range, 3.0-19.5). SDR guided by electrophysiological monitoring was performed by a single experienced neurosurgeon. All subjects received equivalent physiotherapy. The primary outcome measure was change to the degree of spasticity following SDR. Spasticity of upper and lower limb muscle groups were quantified and standardised using the Ashworth score. Measures were collected at baseline and at 2-, 8- and 14-month postoperative intervals. In addition, baseline and 6-month postoperative urological function was also evaluated as a secondary outcome measure. RESULTS The mean lower limb Ashworth score at baseline was 3.2 (range, 0-4). Following SDR, significant reduction in lower limb spasticity scores was observed at 2 months and maintained at 8 and 14 months postoperatively (Wilcoxon rank, p < 0.001). The mean reduction at 2, 8 and 14 months was 3.0, 3.2 and 3.2 points respectively (range, 1-4), confirming a sustained improvement of spasticity over a 1-year period of follow-up. Significant reduction in upper limb spasticity scores following SDR was also observed (mean, 2.9; Wilcoxon rank, p < 0.001). Overall, the improvement to upper and lower limb tone following SDR-generally to post-treatment Ashworth scores of 0-was clinically and statistically significant in GMFCS IV and V patients. Urological assessment identified pre-existing bladder dysfunction in 70% and 90% of GMFCS IV and V patients respectively. Following SDR, improvement in urinary continence was observed in 71% of affected GMFCS IV and 42.8% of GMFCS V patients. No serious postoperative complications were identified. CONCLUSIONS We conclude that SDR is safe and-in combination with physiotherapy-effectively reduces spasticity in GMFCS grade IV and V patients. Our series suggests that spastic quadriplegia is effectively managed with significant improvements in upper limb spasticity that are commensurate with those observed in lower limb muscle groups. These gains are furthermore sustained more than a year postoperatively. In light of these findings, we propose that SDR constitutes an effective treatment option for GMFCS IV and V patients and a rational alternative to intrathecal baclofen.

Abstract
Background: Spasticity is a motor disorder that interferes with mobility and affects the quality of life. Different approaches have been utilized to address patients with spastic diplegia, among which is selective dorsal rhizotomy (SDR). Although SDR has been shown to be efficacious in treating spastic patients, many neurologists and neurosurgeons are not well aware of the procedure, its indications, and expected outcomes due to the limited number of centers performing this procedure. Objectives: The aim of this study is to describe the collaborative multidisciplinary approach between neurosurgeons, neurophysiologists, and physiotherapists in performing SDR. In addition, we delineate three illustrative cases in which SDR was performed in our patients. Materials and Methods: A retrospective review and analysis of the clinical records of our three patients who underwent SDR was conducted and reported. Patients’ outcomes were evaluated and compared to preoperative measurements based on clinical examination of power, tone (Ashworth scale), gait, and range of motion, as well as subjective functional assessment, gross motor function classification system, and gross motor function measure with follow-up at 6, 12, and 24 months postoperatively. A detailed description of our neurosurgical technique in performing SDR in collaboration with neurophysiology and physiotherapy monitoring is provided. Results: The three patients who underwent SDR using our multidisciplinary approach improved both functionally and objectively after the procedure. No intraoperative or postoperative complications were encountered. All patients were doing well over a long postoperative follow-up period. Conclusion: A multidisciplinary approach to treating spastic diplegia with SDR can provide good short-term and long-term outcomes in select patients suffering from spastic diplegia.

Childs Nerv Syst 2016; 32:321-5. [PMID: 26552383 DOI: 10.1007/s00381-015-2950-9] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2015] [Accepted: 10/27/2015] [Indexed: 12/26/2022]
Abstract
BACKGROUND Conventionally, selective dorsal rhizotomy (SDR) has been reserved for ambulant children and implantation of intrathecal baclofen (ITB) pump for non-ambulant children with cerebral palsy. Rather than replacing the ITB pump in selected Gross Motor Function Classification System (GMFCS) grades 4 and 5 children, we elected to undertake SDR instead. We discuss the rationale and outcomes. OBJECTIVES To assess if children with severe spasticity treated with long-term ITB pump would benefit from SDR as alternative procedure to replacement of ITB pump. METHOD This study is a prospective review of ten children with severe spasticity. Indications for ITB pump replacement in 3/10 children were previous ITB pump infection and the remaining seven were nearing depletion of drug delivery system. Pre- and post-SDR mean modified Ashworth scores, assessment of urological function and survey of parent/carer satisfaction were undertaken. RESULT Mean Ashworth score reductions post-SDR in the lower limbs and upper limbs were 2.4 and 1.70, respectively. An improvement in urological function was also noticed in 27% of patients. Overall, 90% of parents/carers felt that functional outcome with SDR was improved compared with that of ITB. CONCLUSION SDR in comparison to ITB in this subgroup is cheaper, less intrusive by avoiding refills/replacement and found to be more effective than ITB in reducing spasticity and providing ease for nursing care. We therefore suggest that consideration should be given to SDR as an alternative in patients previously implanted with ITB systems complicated by infection or nearing end of battery life.

Abstract
Tone management is one of the primary roles of a pediatric physiatrist. Hypertonicity frequently inhibits normal movement patterns in children with central nervous system lesions but at times can reinforce muscle group firing and be useful for a child's function. Treatment approaches should be individualized based on functional goals, degree of impairment, interference with care, and type and location of hypertonicity. Treatment plans should be created in collaboration with all individuals caring for the child. There are many causes of hypertonicity as well as many nonsurgical and surgical treatments. Historical and current evidence-based treatments are reviewed.

Abstract
A paradigm shift is currently ongoing in the treatment of spasticity in childhood in Japan. Functional posterior rhizotomy (FPR), which was first introduced to Japan in 1996, is best indicated for children with spastic cerebral palsy, regardless of the clinical severity of spasticity. Surgery is generally carried out in the cauda equina, where the posterior root is separated from the anterior one, and neurophysiological procedures are used to judge which nerve root/rootlet should be cut. The outcome of FPR is favorable for reducing spasticity in the long-term follow-up. Intrathecal baclofen (ITB) treatment for childhood spasticity was approved in 2007 in Japan and the number of children undergoing ITB pump implantation has been gradually increasing. ITB treatment is best indicated for children with severe spasticity, especially those with dystonia, regardless of the pathological background. Since it is a surgery performed to implant foreign bodies, special attention should be paid to avoid perioperative complications such as CSF leakage, meningitis, and mechanical failure. Severely disabled children with spasticity would benefit most from ITB treatment. We would especially like to emphasize the importance of a strategic approach to the treatment of childhood spasticity. The first step is to reduce spasticity by FPR, ITB, and botulinum toxin injection. The second step is to aim for functional improvement after controlling spasticity. Traditional orthopedic surgery and neuro-rehabilitation form the second step of treatment. The combination of these treatments that allows them to complement each other is the key to a successful treatment of childhood spasticity.

Abstract
BACKGROUND The effectiveness of pudendal afferents mapping in posterior sacral rhizotomies needs to be reviewed. OBJECTIVE To evaluate the effectiveness of pudendal afferents mapping for both the dorsal penile or clitoral nerve and the inferior anal nerve to decrease the risk of postoperative bowel and bladder dysfunction when the sacral nerve roots are candidates for rhizotomies. METHODS A retrospective review of 101 Asian children who underwent functional posterior rhizotomies with pudendal afferents mapping for spastic paresis was performed. RESULTS Pudendal mapping was successful in 75 of 81 patients. The highest activity of afferent fibers of the dorsal penile or clitoral nerve was demonstrated at the S1 roots in 13.3%, at the S2 in 79.3%, and at the S3-5 in 7.3%. Considerable activity of the dorsal penile or clitoral nerve was recorded at 40% of the S1 roots, at 99.3% of the S2 roots, and at 52% of the S3-5 roots. The highest activity of afferent fibers of the inferior anal nerve was demonstrated at S2 roots in 42% and at S3-5 roots in 58%. Considerable activity of the inferior anal nerve was recorded at 10.7% of S1 roots, at 89.3% of S2 roots, and at 76.7% of S3-5 roots. The pathological S1 roots were divided into 3 to 4 rootlets, and the rootlets with significant afferent activity were preserved. None of the 75 patients experienced long-term bowel or bladder complications. CONCLUSION Pudendal afferent mapping identified the sacral rootlets involved with genital and anal sensation. The preservation of such rootlets in sacral rhizotomies is considered to be important for minimizing postoperative bladder and bowel dysfunction.

Abstract
The purpose of this study was to use three-dimensional gait analysis to describe the gait status of adults with spastic diplegia who underwent selective dorsal rhizotomy (SDR) in childhood. Outcome measures were the gait deviation index (GDI), non-dimensional temporal-distance parameters, and kinematics of the lower limbs. A total of 31 adults with spastic diplegia who had previously undergone SDR were eligible and participated in current study (SDR group). These participants had a median age of 26.8 years (range 21-44 years) with a mean time between surgery and assessment of 21.2±2.9 years (range 17-26 years). For comparison purposes, 43 typically developed adults also participated (CONTROL group), with a median age of 28.3 years (range 21-45 years). More than 17 years after SDR 58% of the SDR group showed improved GMFCS levels, while none of them deteriorated. The participants in the SDR group walked with a mild crouch gait, although there was a loading response, adequate swing-phase knee flexion, adequate swing-phase plantarflexion, reasonable speed and cadence. The gait status of the SDR group more than 17 years after SDR was similar to what has been reported in short-term follow-up studies, as well as our earlier 20 year follow-up study that did not include 3D gait analysis. Appropriate orthopaedic intervention was required in 61% of the study cohort. Whether the types and numbers of orthopaedic interventions are positively affected by SDR remains an open question. Further studies examining this question are warranted. In addition, long-term follow-up studies focused on other interventions would also be of clinical relevance.

Abstract
Children with spastic cerebral palsy commonly acquire lower extremity musculoskeletal deformities that at some point may need surgical correction. The authors present 58 children with spastic cerebral palsy who underwent selective percutaneous myofascial lengthening of the hip adductor group and the medial or the lateral hamstrings. All the patients were spastic diplegic, hemiplegic, or quadriplegic. The indications for surgery were a primary contracture that interfered with the patients' walking or sitting ability or joint subluxation. Gross motor ability and gross motor function of the children were evaluated using the gross motor function classification system (GMFCS) and the gross motor function measure (GMFM), respectively. The mean time of the surgical procedure was 14 minutes (range, 1 to 27 minutes). All patients were discharged from the hospital setting the same day after the operation. There were no infections, overlengthening, nerve palsies, or vascular complications. Three patients required repeat procedures for relapsed hamstring and adductor contractures at 8, 14, and 16 months postoperatively. At 2 years after the initial operation, all the children improved on their previous functional level; 34 children improved by one GMFCS level, and 5 children improved by two GMFCS levels. The overall improvement in mean GMFM scores was from 71.19 to 83.19.

Abstract
INTRODUCTION The aim of this study was to evaluate the mechanical status of the spine in patients with spastic diplegia 17-26 years after selective dorsal rhizotomy (SDR). METHODS We compared original radiographic reports from our earlier short-term follow-up study with current X-rays. In addition, we obtained magnetic resonance images (MRI) of the spine and additional information regarding back pain and clinical assessments. RESULTS Thirty patients (17 males and 13 females; median age 26.8 years) participated in the current study, with median follow-up times of 4.0 and 21.4 years. Comparison of the X-ray results showed respectively: scoliosis 0% and 57%; kyphosis 0% and 7%; lordosis 21% and 40%; spondylolysis 18% and 37%; and spondylolisthesis grade I occurred in one patient. The only statistically significant difference was found for scoliosis (p < 0.01). The majority had Cobb angles <30 degrees with only two patients with curves of 35 degrees. MRI scans showed spinal stenosis in 27%, black discs in 10%, and disc protrusion in 3%. Daily back pain was reported in 17%, while 23% reported "moderate disability" as a result of back and leg pain. No patient to date has required any surgical intervention on the spine. CONCLUSIONS Except for spondylolisthesis, spinal deformities did appear to progress with time. However, this increase was not marked, and the development of relatively mild scoliosis was the only statistically significant increase. This group of patients requires continued follow-up. Further studies are required to ascertain the natural history of spinal deformity in adults with spastic diplegia who have not had SDR.

Abstract
BACKGROUND The perceived need for electrophysiological guidance (EPG) during selective dorsal rhizotomy (SDR) has limited the frequency with which SDR is performed. The need for EPG during SDR has been questioned. At our institution, of >200 children with SDR for spastic cerebral palsy, 22 children underwent SDR without EPG using clinical guidance (no EPG group). Electrophysiological stimulation was used to distinguish dorsal from ventral roots. The remainder had SDR with EPG. The purpose of this study was to compare outcomes between the groups having SDR with and without EPG. METHODS The 22 patients in the no EPG group were matched with 22 controls in whom EPG was used, with respect to Gross Motor Function Classification System score (GMFCS) and age. The 12-month outcomes with respect to motor function score, hip adductor spasticity (Ashworth), hip abduction range of motion (ROM), quadriceps power [Medical Research Council (MRC)], WeeFIM, Quality of Upper Extremities Skills Test (QUEST), and incidence of complications were compared. RESULTS There were no statistically significant differences preoperatively with respect to GMFCS, age, gross motor function, Ashworth or MRC scores, joint ROM, WeeFIM, or QUEST. At 1 year after SDR, there were no differences between the groups in the incidence of complications or outcome measures. Percentage of dorsal roots cut was similar, but the duration of surgery was significantly shorter in the no EPG group. CONCLUSIONS There was no advantage of doing SDR with EPG compared to no EPG. SDR can reasonably be done in centers where EPG is not available, but electrophysiological stimulation to distinguish dorsal from ventral roots may be useful in avoiding complications.

Abstract
Spasticity and other forms of muscle overactivity caused by cerebral palsy may impair function or ease of care or may cause discomfort or poor body image. The treatment program for a child with spasticity may include allied health therapy, exercise, casting, constraint-induced therapy, oral medications, chemodenervation, intrathecal baclofen, selective dorsal rhizotomy, and orthopedic surgery. Techniques may be combined for greater efficacy and better tailoring to the needs of the child. This article provides an overview of each approach, with a review of significant research findings in support of each.

Abstract
This study retrospectively evaluated the safety and efficacy of selective dorsal rhizotomy (SDR) in participants who underwent a rigorous selection process, uniform surgical procedure, and a standardized postoperative rehabilitation process. Outcome measures assessed were the Ashworth scale for spasticity, the Gillette Gait Index (GGI) for overall gait pathology, oxygen cost for gait efficiency, and the Gillette Functional Assessment Questionnaire (functional walking ability scale; [FAQ]) for functional mobility. Outcomes were evaluated for 136 children (81 males, 55 females; mean age 7y 3mo [SD 2y 1mo], range 3y 5mo-18y 9mo) for an average of 18.3 months (SD 4.4mo) postoperatively. All participants had a diagnosis of cerebral palsy (CP): 10 quadriplegia, 19 triplegia, and 107 diplegia. Preoperative Gross Motor Function Classification System levels were: Level I n=6; Level II n=64; Level III n=59, and Level IV n=7. All outcome measures improved for the group as a whole. Spasticity improved with 66 to 92% of possible gain in Ashworth scores; GGI was 7.5 times more likely to have a good as opposed to a poor outcome; energy efficiency improved in over half of the participants, and the FAQ demonstrated a statistically significant improvement of 0.9 levels (p<0.001). The rate of complications was low, with peri- and postoperative complications resolved by time of discharge.

Abstract
RATIONALE Selective dorsal rhizotomy (SDR) is a surgical technique developed over the past decades to manage patients diagnosed with cerebral palsy suffering from spastic diplegia. It involves selectively lesioning sensory rootlets in an effort to maintain a balance between elimination of spasticity and preservation of function. Several recent long-term outcome studies have been published. In addition, shorter follow-up randomized controlled studies have compared the outcome of patients having undergone physiotherapy alone with those that received physiotherapy after selective dorsal rhizotomy. MATERIALS AND METHODS In this account, we will discuss the rationale and outcome after SDR. The outcome is addressed in terms of the gross motor function measurement scale (GMFM), degree of elimination of spasticity, strength enhancement, range of motion, fine motor skills, activity of daily living, spastic hip, necessity for postoperative orthopedic procedures, bladder and sphincteric function, and finally possible early or late complications associated with the procedure. CONCLUSION We conclude that SDR is a safe procedure, which offers durable and significant functional gains to properly selected children with spasticity related to cerebral palsy.

Abstract
OBJECTIVE The purpose of this report is to review the historical development, current operative techniques, selection criteria, outcomes, and complications of selective dorsal rhizotomy (SDR) for treatment of spastic cerebral palsy (CP). MATERIALS AND METHODS This review is based on a review of literature and personal observations. RESULTS SDR has evolved from the 1960s onwards into a standard neurosurgical procedure for spastic CP. There is much variation in the operative technique among surgeons with respect to the level of exposure, electrophysiological guidance, and extent of rhizotomies. Appropriate selection of patients for SDR requires determination that spasticity, not dystonia, is the major disabling hypertonia and that the lower limbs are maximally involved. Positive outcomes have been well demonstrated in the impairment, functional limitations, and disability dimensions, as per the National Center for Medical Rehabilitation Research Model of Dimensions of the Disabling Process. Complications have been relatively few. CONCLUSIONS SDR is the procedure of choice for treatment of spasticity in spastic diplegic CP and in selected children with spastic quadriplegic CP. Optimal selection and outcomes are achieved using a multidisciplinary approach.

Abstract
The purpose of this report was to outline the various options currently used for treatment of spastic cerebral palsy (CP) and to discuss factors involved in selecting the appropriate treatment modalities for the individual child. In a review of the literature and his personal observations, the author presents an outline of treatment options and the criteria for using each. Therapeutic options include the following: physiotherapy; occupational therapy; oral spasmolytic and antidystonic drugs; botulinum toxin injections; orthopedic procedures; continuous infusion of intrathecal baclofen (ITB); selective dorsal rhizotomy (SDR); and selective peripheral neurotomy. The most commonly used neurosurgical procedures are ITB pump placement and SDR, and these are discussed in the most detail. The author's personal schema for assessment of the child to determine the nature of the hypertonia, the impact of the hypertonia, and the appropriate therapeutic intervention is presented. There are factors that help guide the optimal treatment modalities for the child with spastic CP. The treatment of these children is optimized in the setting of a multidisciplinary team.

Abstract
Data were collected on orthopaedic surgical interventions during the 5 years after surgery, for 35 consecutive children undergoing selective dorsal rhizotomy. At follow-up, 15 children had been operated in the lower limb. The most frequent procedures were subtalar arthrodesis, Achilles tendon lengthening and adductor tendon lengthening. Children with walking capacity were mostly operated with foot surgery and children without walking capacity were mostly operated with hip surgery. The need for orthopaedic surgery was highest among children with walking capacity.

Abstract
INTRODUCTION Selective dorsal rhizotomy (SDR) is an effective treatment for lower extremity spasticity in cerebral palsy. Cortical organization in sensory cortex may be abnormal in cerebral palsy, and deafferentation is known to lead to cortical reorganization in many situations. METHODS We used functional magnetic resonance imaging (fMRI) of hand sensory stimulation to determine if the partial deafferentation of the lower extremity sensory system, associated with SDR, led to any alterations in the cortical somatosensory representation for the upper limbs. Three patients with spastic diplegia were studied with blood oxygen level-dependent (BOLD)-fMRI before and after SDR. fMRI during tactile stimulation of the digits of the right hand was used to map hand somatosensory cortex. Comparison of the cortical maps devoted to the hand before and after SDR assessed for cortical reorganization following partial deafferentation of the lower extremity. RESULTS In the one patient with upper extremity involvement, the hand sensory representation was markedly enhanced following SDR. In the other two patients, a normal pattern, but with diminished activity, was seen compared with preoperative findings. SDR for lower limb spastic diplegia does not lead to extensive reorganization of cortex dedicated to the representation of the upper limb. An essentially normal pattern of activation was seen both before and after SDR. CONCLUSION The relief of attention demands associated with spasticity may explain the modulation in intensity seen after SDR in the patients who exhibited no upper extremity involvement despite lower limb spasticity.

Abstract
The authors performed a review of 79 patients treated by selective dorsal rhizotomy with laminoplasty, 78 of whom were ambulatory, to determine the prevalence of spinal deformities. The mean radiographic follow-up was 4.2 years, the mean clinical follow-up 5.8 years. Scoliosis (11 degrees -24 degrees ) was identified in 13 children, none of whom had a preexisting deformity. There were no significant differences between preoperative and follow-up thoracic kyphosis or lumbar lordosis, although there was a significant difference in lumbar lordosis between sitting and standing radiographs. No progressive or rigid hyperlordotic deformities were observed in the lumbar spine. Spondylolisthesis was identified in nine children (12%) (8/9 grade I), and one patient required an arthrodesis for pain. Spondylolisthesis was correlated with greater lumbar lordosis, stronger hip abductors, and increased popliteal femoral angles preoperatively, and with stronger hip flexors postoperatively. Back pain was identified in 4 of the 79 patients at last follow-up, 2 of whom had spondylolisthesis. As some cases of spondylolisthesis will remain asymptomatic, periodic radiographic follow-up is recommended.

Abstract
No longer are only a limited number of treatments available to help children and their families deal with childhood hypertonia. It is now possible to provide a child with a treatment specific to his or her muscle tone problems and consequently meet the family's functional goals. The prospects can only improve over the next few years, given the level of interest exhibited by pediatric neuro- and orthopedic surgeons supported by pediatricians, pediatric physical and occupational therapists, pediatric neurologists, and pediatric physiatrists.

Abstract
As one component of the upper motor neuron syndrome, spasticity can have a significant functional impact on the child with cerebral palsy. Treatment planning requires the determination that excess tone interferes with some aspect of function, comfort, or care, and takes into consideration carefully devised goals that meet the needs of the patient and the caregiver. Treatment options include physical therapy, oral medications, chemodenervation with botulinum toxin or phenol, rhizotomy, intrathecal baclofen, and orthopedic surgery. The uses and limitations of each is discussed, and evidence for efficacy in cerebral palsy is reviewed.

Abstract
Object. Selective posterior rhizotomy (SPR) may result in considerable benefit for children with spastic cerebral palsy. To date, however, there have been few studies in which validated functional outcome measures have been used to report surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine long-term functional performance outcomes in patients who underwent lumbosacral dorsal rhizotomy performed using intraoperative electrophysiological monitoring.
Methods. The study population was composed of children with debilitating spasticity who underwent SPR and were evaluated by a multidisciplinary team preoperatively and at 6 months and 1 year postoperatively. Quantitative standardized assessments of activities of daily living (ADL) were obtained using the Pediatric Evaluation of Disability Inventory (PEDI). Of 57 patients who met the entry criteria for the study, 41 completed the 3-year assessments and 30 completed the 5-year assessments.
Statistical analysis demonstrated significant improvement in the mobility and self-care domains of the functional skills dimension at 1 year after SPR. The preoperative and 1-, 3-, and 5-year postoperative scaled scores for the mobility domain were 56, 64, 77.2, and 77.8, respectively. The scaled score for the self-care domain increased from 59 presurgery to 67.9, 81.6, and 82.4 at the 1-, 3-, and 5-year postoperative assessments, respectively.
Conclusions. The results of this study support the presence of significant improvements in functional performance, based on PEDI scores obtained 1 year after SPR. The improvements persisted at the 3- and 5-year follow-up examinations. The authors conclude that SPR performed using intraoperative stimulation is valuable in the augmentation of motor function and self-care skills essential to the performance of ADL.

Abstract
OBJECT Selective posterior rhizotomy (SPR) is a well-recognized treatment for children with spastic cerebral palsy (CP). Few investigators have used quantitative outcome measures to assess the surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine the long-term functional outcome of children who had undergone selective dorsal rhizotomy accompanied by intraoperative electrophysiological monitoring. METHODS The study population was composed of children with spastic CP who underwent SPR and were evaluated by a multidisciplinary team preoperatively, and at 6 months and 1 year postoperatively. Quantitative standardized assessments of lower-limb spasticity, passive range of motion, muscle strength, and ambulatory function were obtained. Of the 93 patients who met the entry criteria for the study, 71 completed the 3-year and 50 completed the 5-year assessments, respectively. Statistical analysis demonstrated significant improvements in spasticity, range of motion, and functional muscle strength at 1 year after SPR. The preoperative, 1-, 3-, and 5-year values for the global score of the Gross Motor Function Measure were 64.6, 70.8, 80, and 85.6, respectively. The greatest improvement occurred in the dimensions reflecting lower-extremity motor function, where the mean change was 10.1% at 1 year, 19.9% at 3 years, and 34.4% at the 5-year follow-up review in comparison with the baseline value. This was associated with a lasting improvement in alignment and postural stability during developmental positions, as well as increased ability to perform difficult transitional movements. CONCLUSIONS The results of this study support the presence of significant improvements in lower-limb functional motor outcome 1 year after SPR, and the improvements persist at 3 and 5 years. The authors conclude that SPR in conjunction with intraoperative stimulation is valuable for permanently alleviating lower-limb spasticity while augmenting motor function.

Abstract
Suprasegmental effects following selective posterior rhizotomy have been frequently reported. However, few studies have used validated functional outcome measures to report the surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine the long-term impact of lumbosacral dorsal rhizotomy on fine motor skills. The study population comprised children with debilitating spasticity who underwent SPR and were evaluated by a multidisciplinary team preoperatively, at 6 months and 1 year postoperatively. Quantitative standardized assessments of upper extremity function were obtained using the fine motor skills section of the Peabody Developmental Motor Scales (PDMS) test. Of 70 patients who met the entry criteria for the study, 45 and 25 completed the 3- and 5-year assessments, respectively. Statistical analysis demonstrated significant improvements in grasping, hand use, eye-hand coordination, and manual dexterity at 1 year after SPR. More importantly, all improvements were maintained at 3 and 5 years following SPR. This study supports that significant improvements in upper extremity fine motor function using the PDMS evaluative measure are present after SPR and that these suprasegmental benefits are durable.

Abstract
Management of children with cerebral palsy (CP) is the focus of considerable resources in many countries, so that evaluation of the efficacy for new and established treatments is imperative. Botulinum toxin type A (BTX-A) is a relatively new method of spasticity management in children with cerebral palsy. It has been the focus of extensive research since its application to cerebral palsy 10 years ago. In a systematic review relating to the management of the lower limb in cerebral palsy 156 papers were identified. These were categorized according to Sackett and the World Health Organisation International Classification of Impairments, Disabilities and Handicaps model. We identified 10 randomized trials evaluating the use of BTX-A in the lower limb in children with cerebral palsy in a systematic review. A meta-analysis showed the pooled risk difference between BTX-A and placebo in three trials was 0.25 (95% CI 0.13, 0.37) and 0.23 (95% CI -0.06, 0.53) for two trials of BTX-A and casting using the physicians rating scale. These represent moderate treatment effects that are dosage-dependent. Outcomes were also compared for function in five studies. The type of evidence for BTX-A was graded by each treatment indication and directions for future research were then drawn from the available evidence.

Abstract
Spasticity occurs in children and adults due to a wide range of conditions, including cerebral palsy, head and spinal cord trauma, cerebrovascular accidents and multiple sclerosis. Multiple treatment options have been described, including medical and surgical treatments. Medical treatments include intramuscular botulinum A toxin, oral baclofen and supportive bracing. Surgical approaches include selective posterior rhizotomy, intrathecal baclofen and orthopedic procedures to address deformities. Many reports have been published on these different treatment options, but rarely has a comparison been made between them. Therefore, this review is aimed at comparing selective posterior rhizotomy and intrathecal baclofen injection for spasticity due to cerebral palsy, especially in children.

Abstract
In recent years there have been a number of advances in understanding of predisposing and protective factors in the development of cerebral palsy in infants. Multiple gestation births, maternal infection, and maternal and fetal thrombophilic conditions all predispose to the development of CP in the infant. Opportunities for prevention of CP may develop from an improved understanding of these factors and their mechanisms of operation. Similar progress has been made in the evaluation of treatments for CP and the effects of these treatments on the individual's impairment, function, and disability. Selective posterior rhizotomy and Botulinum toxin A are now widely used in the treatment of spasticity. The challenge remains to determine how effectively these promising interventions can alter long-term function and quality of life outcomes in children and adults with CP.

Abstract
Recent developments in therapeutic interventions for children with spasticity have complicated managerial decision making. A simplified paradigm for the pathophysiology of spasticity is presented, which emphasizes the ways in which treatment modalities disrupt hyperexcitable segmental spinal reflex arcs. Various techniques for the management of spasticity are reviewed, along with factors relevant to proper patient selection for therapeutic intervention. Potential goals for spasticity management are considered as are outcome measures for assessing the efficacy of these technologies.

Abstract
Many neurosurgical procedures have been designed for or applied to the treatment of spasticity arising from different disorders, including cerebral palsy; traumatic, ischemic, or hypoxic brain injury, multiple sclerosis, and spinal cord injury. Neurosurgical procedures are primarily aimed at reducing spasticity by interrupting the stretch reflex at various sites along the spinal reflex arc or attempting to increase the centrally mediated inhibitory influence on the pool of motor neurons in the anterior horn. Surgical interventions for spasticity can be classified into peripheral ablative procedures, such as rhizotomy or peripheral neurectomy, and central ablative procedures, such as cordectomy, myelotomy, or stereotactic procedures. Non-ablative procedures include peripheral nerve or motor point blocks, the implantation of cerebellar or spinal stimulators, and the implantation of subdural catheters for infusion of pharmacologic agents to increase inhibitory activity. Several proposed mechanisms for spasticity are reviewed so that the rationale for the various surgical interventions for spasticity described may be better understood.
