Recurrent Laryngeal Nerve Injury During Anterior Cervical Discectomy and Fusion (ACDF): A Case Presentation and Review of the Literature.

Anterior cervical discectomy and fusion (ACDF) is a surgical procedure used to manage spine pathology including disc herniation, spondylosis, and myelopathy. During the operation, the vertebral segment of interest is accessed via the anterior neck and the disc space is fully resected along with osteophytes to relieve the compression along the affected nerve. While the procedure is regarded as being highly effective in improving symptoms, there are several complications associated with the surgery that patients should be cautioned about. We present a case of a patient with oropharyngeal and cervical esophageal dysphagia and left vocal cord paralysis following a C5/C6, C6/C7, and C7/T1 ACDF for multilevel cervical stenosis and disc herniation. Otolaryngology evaluation confirmed vocal cord paralysis from recurrent laryngeal nerve palsy (RLNP) and the patient's symptoms were managed with a vocal cord injection and speech therapy. This report explores the surgical approach for ACDF along with its complications and postoperative care.

Splenic rupture following prone lateral discectomy and arthrodesis: illustrative case.

BACKGROUND: The prone lateral approach to lumbar spine surgery is known to have a multitude of potential complications, including damage to neurovascular structures, surrounding viscera, and intra-abdominal structures near the surgical site. However, iatrogenic injury to the spleen following prone lateral lumbar discectomy and arthrodesis as a potential complication has not yet been described in the literature. OBSERVATIONS: The authors present the case of a 71-year-old female with a history of L3-S1 laminectomy and L3-5 arthrodesis who underwent a prone lateral discectomy of L2-3 with arthrodesis of the endplates for chronic lower-back pain. On postoperative day 1, the patient developed hypotension unresponsive to pressor medications, significant abdominal pain, and anemia requiring 2 transfusions. Bedside ultrasound revealed free fluid in the abdomen. She then underwent an exploratory laparotomy for splenic injury. LESSONS: Although rare, splenic rupture should be considered as part of the differential diagnosis for patients with hemodynamic instability after lateral surgical approaches to the lumbar spine. Any patient with evidence of hypotension, anemia, and/or abdominal pain following lumbar surgery should be evaluated for splenic injury with an abdominal computed tomography scan and considered for surgical intervention. https://thejns.org/doi/10.3171/CASE23639.

Pseudoulnar palsy with concurrent wrist drop: case report.

Introduction and importance: Pseudoulnar palsy, characterized by weakness in the fourth and fifth digits, is a condition typically attributed to infarction of the medial aspect of the precentral gyrus's "hand knob." This anatomical site is located in the primary motor cortex of the brain, in the posterior lobe of the frontal cortex. This report presents a novel case of pseudoulnar nerve palsy in conjunction with wrist drop stemming from an infarction of the hand knob gyrus. Case presentation: A 78-year-old female with hypertension and hyperlipidemia experienced sudden right wrist weakness and impaired mobility in her fourth and fifth digits. Clinical examinations, including neuroimaging, supported the diagnosis of an infarction in the medial precentral gyrus. Brain MRI confirmed the diagnosis of an acute infarction in the medial precentral gyrus. The patient was treated with enoxaparin, aspirin, and dexamethasone, and was discharged after symptom improvement. Clinical discussion: Unlike the classical presentations, this case highlights the co-occurrence of ulnar and radial deficits following a unique infarction pattern. The distinct presentation of right pseudoulnar palsy with wrist drop was caused by an infarction at the level of the medial aspect of the hand knob. Conclusion: This case underscores the importance of considering the central causes of peripheral-like deficits, especially in older individuals with vascular risk factors, emphasizing the significance of early intervention in mitigating potential long-term consequences. This report contributes to the evolving understanding of central neurological presentations, and serves as a reminder of the need for a comprehensive diagnostic approach.

Knee'd to Know Basis: Informed Consent in Total Hip and Knee Arthroplasty.

Informed consent is the process by which a medical provider explains the benefits, risks, and alternatives to a proposed medical intervention. It is a crucial part of maintaining patient autonomy and is particularly important in the context of elective surgical procedures, such as joint arthroplasty. The goal of this article is to review the topic of informed consent in the context of total joint arthroplasty. In this review, we discuss informed consent in general, considerations for informed consent in general arthroplasty procedures, and special 12 considerations for both hip and knee arthroplasty.

A review of chronic pectoralis major tears: what options are available?

Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal. Repair of chronic tears should be reserved for younger, healthier patients with high functional demands. Although operative management provides better functional outcomes, operative treatment of chronic pectoralis tears can be challenging. Tendon retraction, poor tendinous substance and quality of tissue, muscle atrophy, scar formation, and altered anatomy make direct repairs complicated, often necessitating auto- or allograft use. We review the various graft options and fixation methods that can be used when treating patients with chronic pectoralis major tears.
