Feasibility and Analgesic Efficacy of Thoracolumbar Dorsal Ramus Nerve Block Using Multiorifice Pain Catheters for Scoliosis Surgery: A Prospective Cohort Study.

BACKGROUND: Approximately 38,000 scoliosis surgery correction operations are performed annually in the United States; these operations are associated with considerable postoperative pain which can be difficult to manage. This is largely attributed to an incision spanning multiple vertebral segments with paraspinal muscle dissection and retraction to facilitate the implantation of segmental hardware and rods. Frequently utilized analgesic modalities include intravenous patient-controlled analgesia and epidural analgesia, often in combination. We sought to ascertain the feasibility and analgesic efficacy of continuous thoracolumbar dorsal ramus nerve (TDRN) block using surgically placed multiorifice catheters. METHODS: Forty-two patients diagnosed with idiopathic scoliosis who underwent a posterior spinal fusion (PSF) were enrolled after consent was obtained. Patients were managed utilizing a standardized Enhanced Recovery After Surgery) protocol including a perioperative opioid-sparing regimen. Data were collected at specified time intervals during the recovery period. These data points included pain scores using the Numeric Rating Scale. Parenteral or both oral and parenteral opioid consumption doses were also collected every 4 hours. Any significant postoperative adverse events were recorded as well. RESULTS: A total of 42 patients had surgically placed TDRN catheters, and 40 patients were included in this study. The patients all reported low to moderate pain scores with low opioid consumption postoperatively, while the TDRN catheter delivery of local anesthetic analgesics did not result in significant complications. CLINICAL RELEVANCE: A regional technique utilizing TDRN catheters could be a valuable component of the postoperative pain management protocols for PSF surgery, and additional studies are warranted. CONCLUSION: This study evaluated the feasibility and analgesic efficacy of TDRN catheters for postoperative pain control following multilevel PSF for idiopathic scoliosis. Continuous local anesthetic delivery through TDRN catheters is a feasible and safe technique for postoperative pain control in these patients. Selective blockade of the dorsal rami might have benefits over epidural analgesia or other regional techniques.

Poor socioeconomic status is associated with delayed femoral fracture fixation in adolescent patients.

INTRODUCTION: Healthcare disparities continue to exist in pediatric orthopedic care. Femur fractures are the most common diaphyseal fracture and the leading cause of pediatric orthopedic hospitalization. Prompt time to surgical fixation of femur fractures is associated with improved outcomes. OBJECTIVE: The objective of this study was to evaluate associations between socioeconomic status and timing of femoral fixation in adolescents on a nationwide level. METHODS: The 2016-2020 National Inpatient Sample (NIS) database was queried using International Classification of Disease, 10th edition (ICD-10) codes for repair of femur fractures. Patients between the ages of 10 and 19 years of age with a principal diagnosis of femur fracture were selected. Patients transferred from outside hospitals were excluded. Baseline demographics and characteristics were described. Patients were categorized as poor socioeconomic status (PSES) if they were classified in the Healthcare Cost and Utilization Project's (HCUP) lowest 50th percentile median income household categories and on Medicaid insurance. The primary outcome studied was timing to femur fixation. Delayed fixation was defined as fixation occurring after 24 h of admission. Secondary outcomes included length of stay (LOS) and discharge disposition. RESULTS: From 2016-2020, 10,715 adolescent patients underwent femur fracture repair throughout the United States. Of those, 765 (7.1 %) underwent late fixation. PSES and non-white race were consistently associated with late fixation, even when controlling for injury severity. Late fixation was associated with decreased rate of routine discharge (p < 0.01), increased LOS (p < 0.01) and increased total charges (p < 0.01). CONCLUSION: Patients of PSES or non-white race were more likely to experience delayed femoral fracture fixation. Delayed fixation led to worse outcomes and increased healthcare resource utilization. Research studying healthcare disparities may provide insight for improved provider education, implicit bias training, and comprehensive standardization of care.

Bilateral Knee Lyme Arthritis in Children: A Report of 3 Cases.

CASES: Three patients presented with bilateral knee pain, effusion, decreased range of motion, and difficulty ambulating. Synovial analysis demonstrated leukocytosis in bilateral knees with positive serum enzyme-linked immunosorbent assay. All cases were managed with antibiotics and anti-inflammatories. One patient developed chronic Lyme arthritis and underwent arthroscopic synovectomy. CONCLUSION: Bilateral knee arthritis is a possible presentation of Lyme disease in children. Accurate diagnosis and treatment with antibiotics and anti-inflammatories can lead to satisfactory outcomes. Arthroscopic synovectomy may be indicated if conservative treatment fails.

Thoracolumbar Dorsal Ramus Nerve Block Using Continuous Multiorifice Infusion Catheters: A Novel Technique for Postoperative Analgesia After Scoliosis Surgery.

BACKGROUND: This is a brief technical report about a novel regional anesthesia technique in which local anesthetic was deposited around the thoracolumbar dorsal rami nerves via 4 multiorifice pain catheters to obtain analgesia for posterior spinal fusion surgery on scoliosis patients. Scoliosis is the most common deformity of the spine. Currently, most surgeons prefer a dual rod, segmental spinal fixation system that allows multiple anchor points for attachment to the deformed spine. Scoliosis surgery is an extremely painful surgical procedure due to the large incision, surgical trauma to superficial and deep muscles of the back, and the insertion of pedicle screws and metal rods directly into the vertebral column. Postoperative pain management remains very challenging. METHODS: Three patients presented with scoliosis. Intraoperatively, 4 multiorifice catheters were placed lateral to the implanted pedicle screws. Two catheters were placed on each side, and a continuous infusion of 0.2 % ropivacaine was initiated postoperatively to improve the patient's pain control. The catheters remained in place for 48 hours postoperatively and were removed by the surgical team. Gentle traction was applied similar to the way epidural catheters are removed. RESULTS: All 3 patients reported very low pain scores, low doses of opioid consumption, and satisfaction with their pain control throughout their hospitalization. CONCLUSIONS: Our study results suggest that a thoracolumbar dorsal ramus nerve block using continuous multiorifice infusion catheters significantly improved postoperative comfort and pain and that its implementation into a multimodal analgesic regimen is relatively easy to achieve.

Bucket-Handle Tear of the Medial Meniscus in a 2-Year-Old Child.

Bucket-handle meniscal tears are extremely rare injuries in the pediatric population. Given the known sequelae of meniscal tears and the development of osteoarthritis, early diagnosis and treatment of pediatric meniscal tears are essential. The communication barrier between physicians and pediatric patients, however, creates difficulties in making the correct diagnosis of meniscal pathology. Providers should have a low threshold for obtaining further confirmatory advanced imaging if patients present with prolonged knee pain and swelling, with associated locking mechanical symptoms. Good clinical outcomes following meniscal repair have been observed, likely a result of the increased residual vascularity found within pediatric menisci. The youngest reported case of an isolated traumatic bucket-handle medial meniscal tear is examined in this article. A 2-year-old girl presented with right knee pain after a heavy object fell onto the knee several weeks earlier. On examination, the patient walked with a limp but lacked full range of active knee motion. The McMurray test elicited pain without a mechanical or palpable click. After the patient continued to exhibit limitations following conservative management, magnetic resonance imaging of the right knee was obtained, which showed a bucket-handle tear of the right medial meniscus. The patient subsequently underwent meniscal repair and, on recovery, was able to regain normal functioning of the right knee without limitations. [Orthopedics. 2018; 41(4):e580-e582.].
