Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery, is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor.
Schematic diagram of the medial side of the elbow showing the ulnar nerve passing through the cubital tunnel. Chronic compression of the ulnar nerve in the cubital tunnel is known as cubital tunnel syndrome. [4] There are several sites of possible compression, traction or friction of the ulnar nerve as it courses behind the elbow. [5]
Ulnar nerve neuropathy, Cervical myelopathy Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi .
Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There are both non-surgical and surgical treatment options. [5]
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
Cubital tunnel syndrome is an entrapment neuropathy, or nerve compression syndrome, a condition caused by compression, traction or friction, of the ulnar nerve at the elbow. [1] Nerve compression is also known as a trapped nerve. The ulnar nerve travels from the shoulder (brachial plexus) down the length of the arm to the hand.
Other options to surgery are a cortisone injection, and use of a splint, to secure the elbow, a conservative procedure endorsed by some. In cases where surgery is needed, cubital tunnel release, where the ligament of the cubital tunnel is cut, thereby alleviating pressure on nerve can be performed. [9] [13] [14]
A nerve graft will be about 10 percent longer than the gap between the nerves, and the cross-section of the nerve end will be a quite larger than the diameter of the nerve graft to allow for growth. The use of harvested nerve grafts from a donor nerve provider contain Schwann cells and basal lamina endoneurial tubes that provide growth factors ...
