Comparing Electrical Stimulation With and Without Ultrasound Guidance for Phenol Neurolysis to the Musculocutaneous Nerve.

Background: Ultrasound guidance is increasingly being used for neurolytic procedures that have traditionally been done with electrical stimulation (e-stim) guidance alone. Ultrasound visualization with e-stim-guided neurolysis can potentially allow adjustments in injection protocols that will reduce the volume of neurolytic agent needed to achieve clinical improvement.

Objective: This study compared e-stim only to e-stim with ultrasound guidance in phenol neurolysis of the musculocutaneous nerve (MCN) for elbow flexor spasticity.

Effects of Anesthetic Fluid Injectates on Lesion Sizes in Cooled Radiofrequency Ablation.

Study Design: Nonrandomized trial.

Objective: This is an ex vivo study using pork chops to simulate human vertebra to determine the effects of various anesthetic fluids injectates and concentrations on lesion size and shape created when using cooled radiofrequency ablation. Secondary objective is to determine the effects of various time durations of applied lesion on lesion size created.

Lateral Antebrachial Cutaneous Nerve Entrapment After Shoulder Arthroscopy: A Case Report.

The lateral antebrachial cutaneous nerve (LABCN) is a distal sensory branch of the musculocutaneous nerve that innervates the radial aspect of the forearm. Cases of LABCN injury from trauma and chronic compression have been reported. A case of musculocutaneous nerve injury after a biceps tenodesis has also been reported.
