MediVisuals' Massachusetts Justice Reports

$1,750,000.00 Settlement - Mistakenly Severed Ulnar Nerve

Congratulations to Eric Parker, Esq. and Susan Bourque, Esq. of Parker Scheer, LLP ( in Boston, Massachusetts for the settlement they reached on behalf of their client, who suffered complete ulnar nerve transection during a procedure to remove a mass from the man's bicep.

Once the surgery was underway, the defendant doctor acknowledged the potential for nerve disruption and even requested a consult from another doctor due to her own misgivings. Neither the defendant doctor nor the consulting doctor was sure of the diagnosis or innervation of the mass. Regardless, the defendant doctor continued with the removal procedure, and consequently, she completely severed the plaintiff's right ulnar nerve.

Despite immediate emergency attempts at repair, the transection left the plaintiff with partial and permanent paralysis of his right arm and hand. The plaintiff was previously employed as a heavy equipment operator and as a result of his injury, is unable to work.

The plaintiff team held the position that the defendant doctor was negligent in her decision to continue with the procedure after encountering a mass with unknown nerve involvement. A Schwannoma, the type of mass found in the plaintiff, can be successfully removed without nerve damage by surgeons with experience handling this type of intra-muscular mass.

Mr. Parker and Ms. Bourque entrusted MediVisuals to provide exhibits explaining the type of mass the surgeon encountered and the procedure used to remove it.

Intervertebral disc injuries that result in them being defined as bulges, herniations, protrusions, extrusions, etc.  The way disc pathology is defined may even vary from physician to physician—perhaps primarily due to the fact that, prior to 1995, many physicians’ professional societies used different criteria to define the various classifications of disc injuries.  In 1995, a joint undertaking by representatives from the North American Spine Society, the American Society of Spine Radiology, and the American Society of Neuroradiology worked together to develop a more widely accepted and used system to define disc pathology as published in "Nomenclature and Classification of Lumbar Disc Pathology”.

This will be the first of three blogs dedicated to helping explain the definitions of disc pathology as recommended by the 1995 combined task force. This blog will focus on the difference between "bulges" and "herniations". Topics to be discussed in future articles are differences between a "Herniated Disc" and an "Annular Tear" and the difference between "Protrusions" and  "Extrusions".

In the image below, a normal disc is shown in comparison to the two types of intervertebral disc injuries covered in this article: "Bulges" and "Herniations". Disc "Bulges", in general, are defined by the presence of disc material beyond the normal margins around at least 50% of the disc's circumference. A "Herniation" is defined as displacement of disc material beyond the limits of the intervertebral disc space that extends less than 50% around the circumference of the disc. The displacement material can consist of the nucleus, the annulus, or parts of both. This is significant in personal injury litigation because the defense often places a great deal of emphasis on whether disc pathology is defined as a "bulge" or "herniation" when determining the severity of an injury. However, a "bulge" can actually impinge nerve roots or the spinal cord to a more severe degree than a "herniation".

The next image compares the normal disc to two different types of disc "Bulges". A "Bulge" is defined as "Symmetrical" when the right and left sides of the herniation more or less mirror each other.  A bulge is "Asymmetrical" when the bulge is more severe on one side when compared to the other.

Finally, the below image shows a normal disc as compared to two types of "Herniations". A "Broad-Based" herniation is defined as disc material extending beyond its normal limits in an area between 25 and 50% of the disc's circumference.  A "Focal" herniation is one involving extension of disc material beyond its normal limits in less than 25% of its circumference.
