Abstract
BACKGROUND Spasticity of the elbow flexors causes a dynamic and/or static elbow flexion deformity. This position interferes with the functional use of the hand, is aesthetically unpleasant and can cause problems with hygiene and comfort. A lengthening procedure of elbow flexor muscles can improve elbow posture and range of motion. However, causal spasticity is not addressed directly. Selective neurectomy of the musculocutaneous nerve has a direct effect on underlying spasticity but is not sufficient when contracture is present. In this study, we examine the long-term results of a combined surgical approach: a release procedure of the elbow flexors and selective neurectomy of the musculocutaneous nerve. METHODS A retrospective study of 14 patients with spastic flexion deformity of the elbow was performed. After a mean follow-up of 52.6 months (SD 33, range 12 to 113), the results of the combined surgical approach were evaluated. Spontaneous position of the elbow and active and passive range of motion were assesses using goniometry. Spasticity was assessed using the Modified Ashworth Scale. Function of the affected upper limb before and after surgery was assessed by the House functional classification. Patient and caretaker's satisfaction were assessed using a visual analogue scale. RESULTS The mean decrease of passive elbow extension deficit was 34 degrees (SD 21.3, P <0.05). Active elbow extension increased with a mean of 41 degrees (SD 16.5, P <0.05). Spontaneous position elbow flexion decreased by a mean of 40 degrees (SD 21.1, P <0.05).The Modified Ashworth score decreased significantly ( P <0.05) from 3.27 (range 1 to 4) preoperatively to 0.64 (range 0 to 4) postoperatively.The difference between the House score preoperatively and postoperatively was not significant ( P =0.180). Mean patient satisfaction was 8.2/10 (SD 2.7, range 2 to 10) and mean caregiver satisfaction was 7.1/10 (SD 2.7, range 1 to 10). CONCLUSION A combined surgical approach to elbow flexion deformity in the form of a lengthening procedure and selective neurectomy of the elbow flexors result in a significant and sustained improvement of the spontaneous position, active and passive elbow extension and elbow flexor spasticity and high patient and caregiver satisfaction. LEVEL OF EVIDENCE Case series, level IV.

Abstract
Spasticity is a potentially debilitating symptom of various acquired and congenital neurologic pathologies that, without adequate treatment, may lead to long-term disability, compromise functional independence, and negatively impact mental health. Several conservative as well as non-nerve targeted surgical strategies have been developed for the treatment of spasticity, but these may be associated with significant drawbacks, such as adverse side effects to medication, device dependence on intrathecal baclofen pumps, and inadequate relief with tendon-based procedures. In these circumstances, patients may benefit from nerve-targeted surgical interventions such as (i) selective dorsal rhizotomy, (ii) hyperselective neurectomy, and (iii) nerve transfer. When selecting the appropriate surgical approach, preoperative patient characteristics, as well as the risks and benefits of nerve-targeted surgical intervention, must be carefully evaluated. Here, we review the current evidence on the efficacy of these nerve-targeted surgical approaches for treating spasticity across various congenital and acquired neurologic pathologies.

Abstract
This article reviews the recent advances or nerve-oriented surgical procedures in the treatment of the spastic upper limb. The idea to intervene on the nerve is not recent, but new trends have developed in nerve surgery over the past few years, stimulating experiments and research. Specific surgical procedures involving the nerves have been described at different levels from proximal to distal: at the cervical spinal cord and the dorsal root entry zone (rhizotomy), at the level of the roots (contralateral C7 transfer) or in the peripheral nerve, within the motor trunk (selective neurectomy) or as its branches penetrate the muscles (hyperselective neurectomy). All of these neurosurgical procedures are only effective on spasticity but do not address the other deformities, such as contractures and motor deficit. Additional procedures may have to be planned in conjunction with nerve procedures to optimize outcomes.

Abstract
Neurotomy interrupts the stretch reflex and can be used for the treatment of spasticity. We hypothesized that neurotomy with nerve repair reduces spasticity while preserving motor function due to the preferential recovery of efferent over afferent fibres. This study reports the 1-year outcomes of neurotomy and immediate repair of the musculocutaneous nerve in the proximal arm for treatment of elbow flexor spasticity, comparing these to outcomes in the literature for neurectomy without nerve repair. A total of 10 adult patients with spasticity of the elbow flexors from stroke or traumatic brain injury who had undergone neurotomy and immediate repair of the musculocutaneous nerve were prospectively studied. The results suggest that this procedure effectively reduces elbow flexor spasticity, improves elbow resting position, active elbow extension and is useful for achieving patient goals with effects lasting at least 12 months.Level of evidence: IV (therapeutic).

Abstract
Selective neurectomy refers to the targeted transection of motor nerve fibres at their entry into the muscle in order to reduce the increased muscle tone in cases of spastic paralysis. This procedure has regained popularity in recent years, especially in the upper extremity. First and foremost, it requires an exact knowledge of the topographical anatomy of muscle innervation. To be able to control the extent and localisation of the denervation, the terminal nerve branches must be visualized precisely during the procedure. For a meaningful reduction of muscle tone, 2/3 to 4/5 of nerve fibres must be resected. This article presents the historical development, principles and operative details of this technique as well as clinical results.

Lateral Pectoral Nerve Identification through Ultrasound-Guided Methylene Blue Injection during Selective Peripheral Neurectomy for Shoulder Spasticity: Proposal for a New Procedure.

Abstract
Internally rotated and adducted shoulder is a common posture in upper limb spasticity. Selective peripheral neurectomy is a useful and viable surgical technique to ameliorate spasticity, and the lateral pectoral nerve (LPN) could be a potential good target to manage shoulder spasticity presenting with internal rotation. However, there are some limitations related to this procedure, such as potential anatomical variability and the necessity of intraoperative surgical exploration to identify the target nerve requiring wide surgical incisions. This could result in higher post-surgical discomfort for the patient. Therefore, the aim of our study was to describe a modification of the traditional selective peripheral neurectomy procedure of the LPN through the perioperative ultrasound-guided marking of the target nerve with methylene blue. The details of the localization and marking procedure are described, as well as the surgical technique of peripheral selective neurectomy and the potential advantages in terms of nerve localization, surgical precision and patients' post-surgical discomfort. We suggest that the proposed modified procedure could be a valid technique to address some current limitations and move the surgical treatment of spasticity toward increasingly tailored management due to the ease of nerve identification, the possibility of handling potential anatomical variability and the resulting smaller surgical incisions.

Abstract
PURPOSE This study aims to determine the utility of selective partial neurectomy of the musculocutaneous nerve (MCN) in pediatric patients with bilateral spastic elbow. METHODS A prospective, cross-sectional, case series study was performed in nine pediatric patients (four females and five males) with bilateral spastic elbow, all with a 11.4-year-old average age, where 18 selective partial neurectomies of the MCN were carried out. They were evaluated with goniometry of both spastic elbows at resting position and active amplitude, and staging spasticity employing the Modified Ashworth Scale (MAS) in the preoperative and postoperative period. The results are reported 1 year after surgery. RESULTS The etiology of the spasticity was secondary to cerebral palsy in eight patients (88.8%) and in one patient (11.11%) secondary to traumatic brain injury. A clinical improvement was observed in goniometry comparing the preoperative and postoperative resting position, a mean preoperative of 44.38 degrees (SD ± 7.61) versus 98.05 degrees (SD ± 24.44), respectively, and preoperative active amplitude a mean of 86.55 degrees (SD ± 15.97) versus the mean postoperative of 47.33 (SD ± 17.86). A relevant decrease on the MAS after surgical intervention was observed, resulting from an average preoperative state according to MAS of 3.78 (SD ± 0.42) to a postoperative state according to MAS of 1.44 (SD ± 0.51), these changes being statistically significant (p ≤ 0.001). No postoperative complications were observed. CONCLUSIONS Selective partial neurectomy of the MCN has shown good results in patients with bilateral spastic elbow in whom antispastic drugs and physical therapy have failed, and has prove permanent effects.

Acta Neurochir (Wien) 2023; 165:1179-1188.

Abstract
BACKGROUND Hyperselective neurectomy is a reliable treatment for spasticity. This research was designed to quantify the surgical parameters of hyperselective neurectomy of thoracodorsal nerve for shoulder spasticity through anatomical studies, as well as to retrospectively assess patients who underwent this procedure to provide an objective basis for clinical practice. METHODS On nine embalmed adult cadavers (18 shoulders), we dissected and observed the branching patterns of thoracodorsal nerve, counted the number of nerve branches, measured the distribution of branch origin point, and determined the length of the surgical incision. Next, we selected five patients who underwent this procedure for shoulder spasticity and retrospectively evaluated (ethic committee: 2022-37) their shoulder function with active/passive range of motion (AROM/PROM) and modified Ashworth scale (MAS). RESULTS The anatomical study revealed that the main trunk of thoracodorsal nerve sends out one to three medial branches, with the pattern of only one medial branch being the most common (61.1%); there were significant variations in the branch numbers and nerve distributions; the location of thoracodorsal nerve branches' entry points into the muscle varied from 27.2 to 67.8% of the length of the arm. Clinical follow-up data showed significant improvement in shoulder mobility in all patients. AROM of shoulder abduction increased by 39.4° and PROM increased by 64.2° (P < 0.05). AROM and PROM of shoulder flexion increased by 36.6° and 54.4°, respectively (P < 0.05). In addition, the MAS of shoulder abduction (1.8) and flexion (1.2) was both significantly reduced in all patients (P < 0.05). CONCLUSION Hyperselective neurectomy of thoracodorsal nerve is effective and stable in the treatment of shoulder spasticity. Intraoperative attention is required to the numbers of the medial branch of thoracodorsal nerve. We recommend an incision in the mid-axillary line that extends from 25 to 70% of the arm length to fully expose each branch.

Abstract
Treatment of spastic syndrome and muscular dystonia in patients with cerebral palsy is a complex clinical problem. Effectiveness of conservative treatment is not high enough. Modern neurosurgical techniques for spastic syndrome and dystonia are divided into destructive interventions and surgical neuromodulation. Their effectiveness is different and depends on the form of disease, severity of motor disorders and age of patients. OBJECTIVE To evaluate the effectiveness of various methods of neurosurgical treatment of spasticity and muscular dystonia in patients with cerebral palsy. MATERIAL AND METHODS We To evaluate the effectiveness of various methods of neurosurgical treatment of spasticity and muscular dystonia in patients with cerebral palsy.analyzed literature data in the PubMed database using the keywords «cerebral palsy», «spasticity», «dystonia», «selective dorsal rhizotomy», «selective neurotomy», «intrathecal baclofen therapy», «spinal cord stimulation», «deep brain stimulation». RESULTS Effectiveness of neurosurgery was higher for spastic forms of cerebral palsy compared to secondary muscular dystonia. Destructive procedures were the most effective among neurosurgical operations for spastic forms. Effectiveness of chronic intrathecal baclofen therapy decreases in follow-up due to secondary drug resistance. Destructive stereotaxic interventions and deep brain stimulation are used for secondary muscular dystonia. Effectiveness of these procedures is low. CONCLUSION Neurosurgical methods can partially reduce severity of motor disorders and expand the possibilities of rehabilitation in patients with cerebral palsy.

Abstract
STUDY DESIGN Descriptive study. OBJECTIVES The study's main objective was to describe the common targets of phenol neurolysis and review the safety and efficacy of the dose used for this spasticity management procedure in people with spinal cord injury (SCI). SETTING An acute rehabilitation hospital. METHODS Data from people with SCI who underwent phenol neurolysis procedures for spasticity management between April 2017 and August 2018 were included in this study. We collected demographics and phenol neurolysis procedure-related information. RESULTS A total of 66 people with SCI and spasticity underwent phenol neurolysis of 303 nerves over 102 encounters. During these encounters, 97% of procedures were performed using both electrical stimulation and ultrasound guidance. The median (IQR) total volume of 6% aqueous phenol used per encounter was 4.0 (2.0-6.0) ml with a median (IQR) of 1.5 (1.0-2.3) ml per nerve. The most frequent target was the obturator nerve (33%), followed by the pectoral nerves (23%). Immediate post-phenol neurolysis improvement or reduction in spasticity was reported for 92% of all documented encounters. There was no documentation of any post-procedure-related adverse events in this cohort during this specified time frame. CONCLUSIONS Our findings suggest that phenol neurolysis can be safely used to manage spasticity in people with SCI under combined electrical stimulation and ultrasound guidance. Further research is required to assess the procedure's safety, efficacy, and cost-effectiveness on patient-reported outcomes compared to other spasticity interventions.

Abstract
OBJECTIVE Selective tibial neurotomy (STN) has been indicated for spastic equinus foot (SEF); however, the impact of this procedure on quality of life and activities of daily living has not been evaluated in detail. This study aimed to evaluate the surgical outcomes of STN and its effect on SEF accompanied by pain. METHODS We evaluated 26 patients (mean age: 59.6 ± 15.2 years; 14 men and 12 women) who underwent STN for SEF, 10 of whom complained of spontaneous pain preoperatively. We used the following scales for clinical evaluation: the Modified Ashworth Scale, Medical Research Council (MRC), 10-m walking test, Functional Independence Measure, and numeric rating scale for pain. These scales were evaluated preoperatively and postoperatively. Differences in clinical characteristics were compared between the 10 patients with pain and the 16 patients without pain. RESULTS Significant differences were observed in all evaluation scale scores except for the Functional Independence Measure, and no serious adverse events were reported. Pain intensity was significantly improved from 6.4 ± 2.0 to 2.7 ± 2.3 (P < 0.05). An analysis showed that the preoperative mean Medical Research Council score of ankle movement was significantly lower in patients with pain but recovered to the same level postoperatively at the 6-month follow-up. CONCLUSIONS Our study showed significant improvements in spasticity and its associated symptoms, and STN effectively addressed spastic pain and motor weakness. Among various treatment modalities, STN may be positively indicated for patients with spastic pain in the lower leg.

Abstract
Objective To explore the therapeutic effect of combined selective peripheral neurotomy (cSPN) on the spasm of the lower limbs after spinal cord injury. Methods A prospective intervention (before-after trial) with an observational design was conducted in 14 spinal cord injury patients with severe lower limbs spasticity by cSPN. Given the severe spasm of hip adductor, triceps surae, and hamstring muscles in these patients, a total of 26 obturator nerve branches, 26 tibia nerve branches, and 4 sciatic nerve branches partial neurotomy were performed. The modified Ashworth scale, composite spasticity scale, surface electromyography, gait analysis, functional ambulation category, spinal cord independence measure, and modified spinal cord injury–spasticity evaluation tool were used before and after surgery. Results Compared with preoperative, the spasm of the hip adductor, triceps surae, and hamstrings of the lower limbs in the postoperative patients decreased significantly. The abnormal gait of knee flexion and varus in the standing stage were significantly reduced. The grading of walking ability and activities of daily living were significantly improved. Conclusions Combined selective peripheral neurotomy can significantly reduce the spasm of lower limbs post spinal cord injury, improve abnormal gait, and improve motor function and activities of daily living.

Abstract
Hyperselective neurectomy (HSN) procedures in the spastic upper limb aim to reduce tone by excising some branches of the involved peripheral motor nerves, at the point of entry of each motor ramus into the target muscle. In this prospective study, 42 patients with upper limb spasticity were treated by HSN for the muscles of elbow flexion, forearm pronation and wrist flexion and evaluated for their short-term results (average 6 months) and long-term outcomes (average 31 months). Results at both time points showed an effective reduction of the spastic tone, with no decrease of muscle strength in the operated spastic muscles. Comparison of results between the two time points showed durability of the improvement, which remained statistically significant despite a slight relapse in spasticity. The results of HSN compare favourably with the other techniques of partial neurectomy; however, the technique requires a detailed knowledge of upper limb motor anatomy.Level of evidence: II.

Abstract
Introduction: Spasticity is the main complication of many upper motor neuron disorders. Many studies describe neuro-orthopedic surgeries for the correction of joint and limb deformities due to spasticity, though less in the upper extremity. The bulk of care provided to patients with spasticity is provided by rehabilitation clinicians, however, few of the surgical outcomes have been summarized or appraised in the rehabilitation literature. Objective: To review the literature for neuro-orthopedic surgical techniques in the upper limb and evaluate the level of evidence for their efficacy in adult patients with spasticity. Method: Electronic databases of MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews were searched for English, French as well as Farsi languages human studies from 1980 to July 2, 2020. After removing duplicated articles, 2,855 studies were screened and 80 were found to be included based on the criteria. The studies were then divided into two groups, with 40 in each trial and non-trial. The results of the 40 trial articles were summarized in three groups: shoulder, elbow and forearm, and wrist and finger, and each group was subdivided based on the types of intervention. Results: The level of evidence was evaluated by Sackett's approach. There were no randomized control trial studies found. About, 4 studies for shoulder, 8 studies for elbow and forearm, 26 studies for wrist and finger (including 4 for the thumb in palm deformity), and 2 systematic reviews were found. Around, two out of 40 trial articles were published in the rehabilitation journals, one systematic review in Cochrane, and the remaining 38 were published in the surgical journals. Conclusion: Most surgical procedures are complex, consisting of several techniques based on the problems and goals of the patient. This complexity interferes with the evaluation of every single procedure. Heterogenicity of the participants and the absence of clinical trial studies are other factors of not having a single conclusion. This review reveals that almost all the studies suggested good results after the surgery in carefully selected cases with goals of reducing spasticity and improvement in function, pain, hygiene, and appearance. A more unified approach and criteria are needed to facilitate a collaborative, evidence-based, patient referral, and surgical selection pathway.

Abstract
BACKGROUND Sedating antispastic medications and focal therapies like botulinum toxin are the most common therapies for spasticity but are temporary and must be performed continuously for a principally static neurological insult. Alternatively, highly selective partial neurectomies (HSPNs) may reduce focal spasticity more permanently. OBJECTIVE To quantify the change in spasticity after HSPN and assess patient satisfaction. METHODS We retrospectively reviewed the records of patients with upper- and/or lower-extremity spasticity treated with HSPN from 2014 to 2018. Only cases with a modified Ashworth scale (MAS) score independently determined by a physical therapist were included. Pre- and postoperative MAS, complications, and patient satisfaction were evaluated. RESULTS The 38 patients identified (24 male, 14 female; mean age 49 yr) underwent a total of 88 procedures for focal spasticity (73% upper extremity, 27% lower extremity). MAS scores were adjusted to a 6-point scale for evaluation. The mean preoperative and final postoperative follow-up adjusted MAS scores were 3.6 and 1.7, respectively (P < .001), which represents average MAS less than 1+. Positive, neutral, and worse results were described by 91%, 6%, and 3% of patients, respectively. Four patients requested revision surgery. No perioperative complications were encountered. CONCLUSION This is the first North American series to analyze HSPN for spasticity and the only series based on independent evaluation results. HSPN surgery demonstrated objective short- and long-term reduction in spasticity with minimal morbidity and excellent patient satisfaction.

Abstract
Spasticity is a common debilitating condition after central nervous system injury. The principal therapies-sedating antispasticity medications and focal therapies (eg, botulinum toxin)-may not provide sufficient reduction in tone, have intolerable side effects, and lose efficacy over time. Selective neurectomy is a surgical option for durable reduction in tone.1-6 Although commonly performed internationally, neurectomies are used less often within the USA. We present the surgical case of a 23-yr-old woman with cerebral palsy and severe spastic diplegia. Medications, injections, and tendon surgeries had failed to relieve her spastic lower extremities. She presented with crouch gait, adductor scissoring, and bilateral equinovarus. She had previously benefitted significantly from bilateral hamstring and obturator neurectomies, with improvement in mobility. She desired tibial neurectomies for her bilateral equinovarus, which impacted her gait substantially. To reduce unwanted plantarflexion and internal rotation tone, selective neurectomies of the motor nerves to the medial and lateral gastrocnemius, soleus, and posterior tibialis muscles were performed. The surgical video details a technique for longitudinally opening the epineurium, separating small nerves into their individual fascicles, and subdividing submillimeter fascicles by approximately 50% to 60% of the fascicle cross-sectional area. She reported significant improvement in gait, her modified Ashworth score dropped from 3 to 0, and her motor power remained unchanged, which is equivalent or better than most published results.2,7 Neurectomies are a highly effective procedure for focal extremity spasticity. Additional clinical series or trials would help establish the appropriate indications and durability and quantify the risks and benefits. The patient consented to treatment and publication.

Abstract
Spasticity can be caused by central nervous system dysfunction, such as cerebral palsy and stroke. The accepted pathogenesis of spasticity is that the muscles are in the state of uninhibited stretch reflex without enough control of central nervous system. So far, there is no ideal way about how to repair central nervous system. However, the uninhibited stretch reflex can be reduced, targeting the posterior root of the spinal cord and peripheral nerves innervating the limbs, which are called selective posterior rhizotomy (SPR) and selective peripheral neurotomy (SPN), respectively. SPN is indicated for focal or multifocal spasticity, which is well accepted due to its low invasiveness and ease of use. How does the operation work? What do we do before and during this operation? Is there any risk to the patients? Our review summarizes the mechanism, indications, preoperative assessments, techniques, and complications of SPN. We hope that the spastic patients, such as pediatric cerebral palsy patients and older stroke patients, will benefit from this surgery.

Abstract
This article overviews the surgical options for hypertonia management in cerebral palsy, both spasticity and dystonia. We review the history and use of intrathecal baclofen. We contrast its use with the indications for selective dorsal rhizotomy and review how it is the optimal technique to lower tone in the ambulatory spastic diplegic patient with cerebral palsy. This article reviews the advent of deep brain stimulation, with an emphasis on selection criteria and expected outcomes in this population. The article reviews the principles and use of selective peripheral neurotomy as it is applied to focal spasticity not requiring systemic tone reduction.

Abstract
Surgery is one element of the rehabilitative care of the spastic upper limb. Different surgical techniques have been advocated to address each of the common deformities and underlying causes, including muscle spasticity, joint contracture, and paralysis. Partial neurectomy of motor nerves has been shown to reduce spasticity in the target muscles. It is effective only for the spastic component of the deformity, which underscores the importance of a preliminary thorough clinical examination. Hyperselective neurectomy, which involves performing a partial division of each motor ramus at its entry point into the target muscle, results in improved selectivity, reliable partial muscle denervation, and durable results.

Abstract
OBJECTIVE Dorsal longitudinal T-myelotomy is a long-established operation to treat severe spastic paraplegia. The present study aimed to report this surgical technique and investigate the efficacy of T-myelotomy for spasticity relief. METHODS All cases undergoing T-myelotomy for treatment of intractable spastic paraplegia during 2009-2017 were included. The severity of spasticity was evaluated with the Modified Ashworth Scale, Penn Spasm Frequency Scale, Adductor Tone Rating Scale, degree of passive range of motion, and occurrence of abdominal muscle spasms. Other clinical assessments included deep tendon reflex assessed by the National Institute of Neurological Disorders and Stroke scale, Babinski sign, healing of decubitus ulcers, and ambulatory status. RESULTS Fourteen patients with a mean age of 39.3 ± 13.4 years were included. The 7 patients with abdominal muscle spasms before surgery had no spasms after surgery. The Babinski sign was absent in all cases after surgery. Unhealed pressure ulcers in all 9 cases were healed after surgery. All 4 patients with a preoperative bed-bound condition were able to ambulate with a wheelchair. A statistically significant improvement in mean Modified Ashworth Scale score, degree of passive range of motion, and National Institute of Neurological Disorders and Stroke scale score was found in the subgroup and overall analyses. There was also a statistically significant improvement in the Penn Spasm Frequency Scale and Adductor Tone Rating Scale scores. CONCLUSIONS Dorsal longitudinal T-myelotomy remains an effective option for the treatment of intractable spastic paraplegia. It is suitable for, and may be an alternative to, intrathecal baclofen therapy for patients with complete spinal cord lesion or patients without hope of regaining motor function.

Abstract
BACKGROUND Severe spasticity adversely affects patient functional status and caregiving. No previous study has compared efficacy between dorsal root entry zone lesioning (DREZL) and selective dorsal rhizotomy (SDR) for reduction of spasticity. This study aimed to investigate the efficacy of DREZL and SDR for attenuating spasticity, and to compare efficacy between these two methods. METHODS All patients who underwent DREZL, SDR, or both for treatment of intractable spasticity caused by cerebral pathology at Siriraj Hospital during 2009 to 2016 were recruited. Severity of spasticity was assessed using Modified Ashworth Scale (MAS) and Adductor Tone Rating Scale (ATRS). Ambulatory status was also evaluated. RESULTS Fifteen patients (13 males) with a mean age of 30.3 ± 17.5 years were included. Eight, six, and one patient underwent DREZL, SDR, and combined cervical DREZL and lumbosacral SDR, respectively. Eight of ten patients with preoperative bed-bound status had postoperative improvement in ambulatory status. Spasticity was significantly reduced in the DREZL group (p < 0.001), the SDR group (p < 0.001), and in overall analysis (p < 0.001). SDR was effective in both pediatric and adult spasticity patients. A significantly greater reduction in spasticity as assessed by MAS score (p < 0.001) and ATRS score (p = 0.015) was found in the DREZL group. Transient lower limb weakness was found in a patient who underwent SDR. CONCLUSIONS DREZL is more effective for reducing spasticity, but is more destructive than SDR. DREZL should be preferred for bed-ridden patients, and SDR for ambulatory patients. Both operations are helpful for improving ambulatory status. Gait improvement was observed only in patients who underwent SDR. Adult patients with spasticity of cerebral origin benefit from SDR.
