What is a posterior interosseous nerve Neurectomy?
Introduction. The posterior interosseous nerve neurectomy (PINN) was first described in 1966 by Wilhelm who performed dorsal wrist denervation in patients presenting with pain due to trauma, necrosis of the lunate, arthritis, and scaphoid nonunions recalcitrant to conservative measures.
What is surgical denervation?
A denervation is a procedure that aims to permanently stop a nerve transmitting pain. The nerve is destroyed by heating it with an electrical current from a special device, called a radio-frequency machine.
How long does wrist denervation surgery take?
The operation takes around 45 minutes and involves four small incisions on both the front and back of the wrist and hand. The incisions are closed with wire sutures and a dorsal plaster splint is applied. Following surgery, grip, strength, wrist motion and pain improves.
What is wrist denervation?
Wrist denervation is a safe and effective procedure for the treatment of chronic wrist pain that can delay or eliminate the need for salvage or anatomically distorting procedure, such as proximal row carpectomy. The traditionally more extensive wrist denervation has evolved to procedures requiring fewer incisions.
Where is the posterior interosseous nerve located?
The posterior interosseous nerve is located close to shaft of the humerus and the elbow. This nerve is the deep motor branch of the radial nerve. Proximal to the supinator arch, the radial nerve is divided into a superficial branch and posterior interosseous branch.
How long does it take to recover from denervation?
It might take up to three weeks for you to feel any benefit, but about half of cases can expect relief from symptoms for between three months and one year. It’s important to know that the nerve can regrow so your pain may come back.
How do you treat posterior interosseous nerve?
The most common treatment was combined muscle release and neurolysis, with heterogeneous results. There is a need for comparative studies. Level of Evidence III, Systematic Review. Keywords: Radial nerve, Nerve compression syndromes/diagnosis, Nerve compression syndromes/therapy, Evidence-based medicine.
Do nerves grow back after denervation?
In clinical practice, nerve regeneration after ablation may recover according to its thickness from tactile sense, motor, proprioception, temperature, pain, and sympathetic tone. However, an itching sensation without pain sometimes remains after denervation, and it recurs at first without recurrence of pain.
How successful is radial tunnel surgery?
The success rate for decompressing of patients suffering from RTS was estimated between 10 to 95% (1). Regardless of the surgical approaches, release of the nerve from the arcade of Frohse and ligating the radial recurrent blood vessels is essential (13).
