Abstract Spinal cord stimulation is a well-established and effective therapy in the treatment of pain. Proper patient selection and accurate lead placement are paramount in its success. Placement is a multifaceted process requiring proper paddle placement, a well thought out generator placement and appropriate means to limit complications and enhance success. Several intraoperative techniques maximize outcomes, including removal of the superior portion of the inferior level's spinous process for paddle access into the epidural space, generator pocket placement in a location that limits patient discomfort, a strain relief loop at the thoracic incision to prevent lead fractures and allow for full spinal flexibility, generator placement parallel to the body and secured in the pocket to prevent unwanted movement, and intraoperative neuromonitoring for patient comfort and more accurate lead placement compared to X-ray alone or awake placement. This case demonstrates these key elements of intraoperative technique in a candidate with the most common indication for spinal cord stimulator placement–postlaminectomy syndrome–underscoring the ease and viability of this procedure in the appropriate patient population in a means that reduces future complications and adverse events while maximizing success.  Full patient consent for video-recording and subsequent use for research purposes was attained. All patient identifiers have been removed for the purpose of patient confidentiality.

ABSTRACT: Congenital malformations are functional and structural changes in organ systems, tissues, or organs that may develop during the embryonic or fetal phase. Spinal cord malformations, such as segmental hypoplasia of the spinal cord (SHSC) and syringomyelia, are rare in bovines. A Girolando calf from Valença, Rio de Janeiro, was admitted to the Veterinary Hospital of Universidade Federal Rural do Rio de Janeiro because of motor incoordination. Clinical evaluation revealed a 5-cm depression area in the spine at the dorsal line of the thoracic region. Neurological examination revealed reduced proprioception, pelvic limb extension with increased nociceptive activity, and reduced anal reflex. In radiographic examination, the body of the T11 vertebra had a trapezoidal wedge shape with ventral hemivertebra, probable agenesis or hypoplasia of the T11-T12 spinous processes, and fusion of the T9-T10 spinous processes. Myelography revealed extradural spinal compression caused by vertebral malformations. Necropsy showed no spinous processes (T11-T12), cranial stenosis in the medullary canal (T11-T13), and 1-3-mm pores in the white matter of the thoracic spinal cord (T8-T11). Microscopy revealed cystic dilatations in the white matter (T9-T11), cystic areas of varying sizes (T8-T9), and moderate reduction in the gray matter around the central canal of the medulla (T11-T13). Here, we reported the clinical and pathological findings of SHSC and syringomyelia in a Girolando calf. The features should be differentiated from other spinal cord syndromes. Congenital malformations are of economic importance, and their etiology and diagnosis are fundamental to disease control and progenitor-selection programs.

A nine-day-old Saanen kid presented for progressive hind limb paresis since birth. Euthanasia was elected, and on postmortem examination a large, pigmented mass was present in the vertebral canal surrounding the lumbosacral and caudal thoracic spinal cord. Histopathology revealed a homogeneous population of round to spindle neoplastic cells containing finely granular pigment consistent with a melanoma. This diagnosis was further supported by a Fontana-Masson stain and immunohistochemistry for PNL2, MelanA and SOX10. The tumour presumably arose from melanocytes or melanocytic precursors within the meninges of the lumbosacral spinal cord. No evidence of neoplasia was seen elsewhere in the body; therefore, the meningeal melanoma likely represents the primary tumour. Goats develop neoplasms less frequently than other species, and reports of congenital tumours in goats are rare.

Background. Spinal cord stimulation is an established treatment option for certain chronic pain conditions which have been previously unresponsive to conservative therapies or potentially for a subset of patients who have not improved following spine surgery. Prior to permanent lead implantation, stimulator lead trials are performed to ensure adequate patient benefit. During these trials, one of the most common complications and reasons for failure is the displacement and migration of the trial leads, resulting in lost therapeutic coverage. Other complications include infection and dislodged bulky dressings. There is a paucity of literature describing an adequate procedural method to prevent these common complications. Objective. This study utilizes a series of 19 patients to evaluate a new technique for securing percutaneous spinal cord simulator trial leads, which may minimize dislodgement and migration complications and improve the rate of trial success. Study Design. Retrospective case series. Setting. New Jersey Medical School, Department of Anesthesiology, Pain Management Division. Methods. A retrospective chart review was conducted on 19 consecutive patients undergoing placement of the percutaneous thoracic spinal cord stimulator trial leads for pain associated with lumbar spine pathology over a two-year period (2010–2012). Results. Of the 19 patients in our cohort, there was one trial lead displacement, no lead migrations, and no site infections. Thirteen patients went on to permanent lead implantation. This improved trial lead placement technique had a high success rate with a low number of complications. Limitations. Small sample size, retrospective case series, and no control group for comparison. Conclusion. This case series was able to demonstrate that our described novel spinal cord stimulator trial lead placement and dressing technique can decrease the incidence of lead displacement and migration, thus improving trial success.

New developments in spinal cord stimulation (SCS) have improved the treatment of patients with chronic pain. Although the overall safety of modern SCS has been established, there are no published reports regarding safety considerations when implanting a burst-mode spinal cord stimulator in patients with permanent cardiac pacemakers (PCPs). An 80-year-old man with a complete atrioventricular block implanted with a PCP was considered as a candidate for burst-mode SCS due to well-established postherpetic neuralgia (>180 days after rash). Cardiac monitoring during the burst-mode spinal cord stimulator trial and insertion did not indicate any interference. After the insertion of the burst-mode spinal cord stimulator, the patient showed functional improvement and significant pain relief. The safety of traditional tonic-mode SCS in patients with PCP has been previously reported. This is the first case report describing the safe and effective use of burst-mode SCS in a patient with PCP.

Abstract Spinal cord herniation is an uncommon surgically treatable cause of thoracic myelopathy and progressive paraplegia. The thoracic spinal cord focally protrudes through a defect in the dura, resulting in progressive weakness, numbness, and spasticity affecting the lower extremities, in addition to possible urinary symptoms. In this video, we present the case of a 69-yr-old female who presented with 3 yr of progressive thoracic myelopathy due to a thoracic spinal cord herniation at T4-T5. We demonstrate the surgical steps to lyse arachnoid webs, mobilize the spinal cord, reduce the spinal cord herniation, and repair the dural defect. Appropriate patient consent was obtained.
