Asymmetrical neck spasms following cervical artificial disc replacement surgery. A neck spasm is an involuntary contraction of the muscles in the neck region. [1 ...
Laterocollis is the tilting of the head from side to side. This is the "ear-to-shoulder" version. This involves many more muscles: ipsilateral sternocleidomastoid, ipsilateral splenius, ipsilateral scalene complex, ipsilateral levator scapulae, and ipsilateral posterior paravertebrals. The flexion of the neck (head tilts forwards) is anterocollis.
CMT is a neck problem that babies are born with or develop soon after birth, causing their neck to be stiff and bent in an awkward position. [38] Besides the sternocleidomastoid muscle, other muscles in the neck can also be affected by CMT, leading to problems moving the head and neck normally. [38]
Clinically this is referred to as an anterior dislocation of the glenohumeral joint. Not only does the arm appear out of position when the shoulder dislocates, but the dislocation also produces pain. Muscle spasms may increase the intensity of pain. Swelling and bruising normally develop, and in some cases there may be numbness and muscle weakness.
The main symptom of benign fasciculation syndrome is focal or widespread involuntary muscle activity (fasciculation). [1] The benign twitches usually have a constant location. [2] Other common symptoms are generalized fatigue or weakness, paraesthesia or numbness, and muscle cramping or spasms. [1]
While neck pain is the second most common cause of disability and cost $100 billion, [2] the NIH budgets only $10 million to the study of neck pain. [3] One of the most common neck pains is between the neck and the shoulder. This is technically over the supraspinatus muscle and not in the neck, but it is still called “neck” pain.
A spasm is a sudden involuntary contraction of a muscle, [1] a group of muscles, or a hollow organ, such as the bladder. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain. A muscle cramp is usually harmless and ceases ...
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle.
