Characterization of standard work tools for intrathecal baclofen therapy.

PURPOSE: Intrathecal baclofen (ITB) has been an effective therapy since the 1980s, with widely reported revision, infection, and complication rates. Publications targeting surgical workflow have resulted in decreased infection and revision rates, but a standard workflow for the entire pathway has not been described. To present, define, and test standard work tools for patients receiving ITB to promote uniformity and standard of care in the field. METHODS: A multidisciplinary approach from the movement disorder program of a tertiary care center defined all steps comprising the ITB pathway, and then developed standard work tools to decrease variability with respect to preoperative workup, day of surgery protocol, post-operative care, and also evaluation and treatment with respect to pump infection or malfunction. RESULTS: Defined steps used at specific points of ITB pathway are presented with a single institution's outcome using the protocol from July 2017 to November 2020. A total of 60 procedures were performed. The overall complication rate was 14.5% at 6 months. Complications included an infection rate of 3.6% at 6 months, wound revision rate of 1.8% at 6 months, CSF leak rate of 1.7% at 6 months, and a 30-day readmission rate related to initial surgery of 6.7%. CONCLUSIONS: Workflow efficiency and optimization for ITB patients can be used to obtain lower complication rates compared to historical cohorts in literature. A single-center, retrospective review highlights this.

Pre- and Postoperative Gait Analysis and Video for Selective Dorsal Rhizotomy in Spastic Diplegia: 2-Dimensional Operative Video.

Severe lower limb spasticity can hinder motor tasks and negatively impacts the quality of life in patients with cerebral palsy. Selective dorsal rhizotomy is a well-established neurosurgical intervention aimed at reducing muscle spasticity in patients with such neuromuscular conditions. Long-term outcomes of selective dorsal rhizotomy have been promising among the authors' institutional series of patients. In this case, we demonstrate the use of L1-S1 osteoplastic laminoplasty and L1-S1 selective dorsal rhizotomy in a 5-year-old male patient with cerebral palsy and spastic lower extremity diplegia. Favorable selection criteria for this case included disabling lower extremity diplegia, young age, good core strength, no cognitive delay, and strong rehabilitation potential. The patient's preoperative functional status was noncommunity ambulator (Gross Motor Function Classification System Level III) with walker use and good dynamic balance. Prior to the procedure, he demonstrated an overall decreased muscle strength in bilateral lower extremities with bilateral hamstring spasticity (Ashworth 3) and bilateral heel cord spasticity (Ashworth 4). Rhizotomy was performed with identification and selective sectioning of dorsal nerve roots with abnormal stimulation patterns. Fibers with unsustained discharge of appropriate muscles were identified and spared. No intraoperative or postoperative complications were encountered. The patient had minimal back pain and surgical morbidity postoperatively. Following the procedure and highly structured inpatient and outpatient rehabilitation therapies, the patient exhibited significant improvement in gait velocity (84%) and gait cadence (66%) at 5 months. Additionally, the patient demonstrated greater independence of activities of daily living and improvements in mobility by Pediatric Evaluation Disability Index. Patient consent was obtained from the parent.
