  • Cervical Spondylosis

    It is typically unilateral. Numbness and weakness follow the same distribution. Some patients will exhibit signs and symptoms of radiculopathy and myelopathy.[aafp.org] For example, in patients with a disc herniation between the sixth and seventh vertebrae, pain radiates into the shoulder, upper arm, elbow, and index and middle fingers.[aafp.org]

  • Cerebral Palsy

    Sensorimotor control dysfunction or dyskinesia is a hallmark of neuromuscular impairment in children with cerebral palsy (CP), and is often implicated in reaching and grasping deficiencies due to a neuromuscular imbalance between the triceps and biceps. To mitigate such muscle imbalances, an innovative[…][ncbi.nlm.nih.gov]

  • Stroke

    Rheumatoid meningitis presenting with a stroke-like attack (RMSA) is a rare manifestation of rheumatoid arthritis (RA). When the patients arrive within the time-window for recombinant tissue plasminogen activator (rt-PA) infusion therapy, no diagnostic protocol has been established. A 55-year-old woman was brought[…][ncbi.nlm.nih.gov]

  • Radial Head Dislocation

    We describe a new procedure for the management of chronic posttraumatic radial head dislocation, which uses two drill holes in the proximal ulna. The holes are placed at the original attachments of the annular ligament and thereby allow repair of the annular ligament (frequently avulsed from one attachment and[…][ncbi.nlm.nih.gov]

  • Subdural Hematoma

    We present a 68-year-old woman who developed acute cerebral subdural hematoma (SDH) early after transforaminal lumbar interbody fusion. Four hours postoperatively, the patient complained of headache and nausea. Enhanced cranial computed tomography showed cerebral SDH. Despite no obvious intraoperative dural[…][ncbi.nlm.nih.gov]
