Elbow instability refers to a condition affecting the elbow joint, in which
jerky arm movement cause the joint to be dislocated from its original
position. This dislocation could be in the form of an outward slide, a
pop or a catch. This kind of dislocation results in the surrounding bones
and ligaments getting damaged, as they undergo stress to restore stability
in the joint. Depending on the bones involved in the dislocation, there
can be three types of elbow instabilities:
Valgus instability: This occurs when a mass of soft tissue within the elbow, referred to as
the ulnar collateral ligament, undergoes an injury.
Posterolateral rotatory instability: This is caused by an injury in a soft tissue structure located outside
the elbow, referred to as the lateral collateral ligament complex.
Varus posteromedial rotatory instability: This instability is caused by a combination of a fracture in the ulna bone,
and an injury in the lateral collateral ligament complex, which causes
the elbow to slide in and out of its original position.
If you are experience any of the symptoms associated with chronic elbow
instability, which include a catching, clicking, locking, popping, pain,
etc., you should visit a doctor at OrthoTexas, Plano, for a detailed examination
of your elbow. Our clinic has a team of health care professionals, including
orthopedic surgeons, spine surgeons, physicians, physical therapists, and

Your consultation will start with a detailed insight into your symptoms
and medical history, after which a physical examination shall be performed
to rule out a deformity in the elbow. You will need to move your arm in
several directions for your doctor to identify the exact location of the
instability. A test for your arm strength will be performed to rule out
injury to the nerves. Depending on the severity of your elbow instability,
your doctor might recommend imaging tests like an x-ray and an MRI (Magnetic
You can discuss various treatment options with your
doctor at OrthoTexas. While nonsurgical treatment options are usually effective in treating
valgus instabilities, you will probably need to undergo surgery if you
are diagnosed with a varus posteromedial instability. In case of posterolateral
rotatory instability, you might need surgery if there is chronic stress
on the ligament. Milder cases of this type of instability can be treated
