Injections and Nerve Blocks

Some hand or arm conditions may not require surgery. MetroHealth's upper extremity Physical Medicine and Rehabilitation (PM&R) physicians work alongside surgeons and physical and occupational therapists to provide pain relief and restore function, using non-operative methods such as injections and diagnostic nerve tests.

Medications and injections can help reduce your symptoms so you can participate in therapy, work or other activities painlessly.

Electromyography (EMG)

Electromyography (EMG) tests are used to diagnose issues with muscle function and the nerves that control muscle movement. An EMG involves inserting needles into the muscle to determine how nerves assist in muscle function. It can be helpful in diagnosing carpal tunnel syndrome.

Nerve conduction studies may also be part of an EMG test. The nerve conduction study measures electrical signals between nerves in the muscle.


Hydrodissection

Hydrodissection procedures free entrapped nerves from pressure, alleviating pain, numbness, or weakness. Fluid is injected into the affected hand or arm, releasing the nerve from pressure. Carpal tunnel syndrome is often treated with hydrodissection.


Platelet-Rich Plasma (PRP) Injection

Platelets are proteins in the blood responsible for healing injuries, like a torn tendon. PRP injections are made of concentrated platelets taken from the patient's own blood, and injected into the injury area. Some evidence suggests PRP injections may help with pain after an injury or surgery.


Steroid Injection

Steroids help treat inflammation and relieve pain. Cortisone injections are used to reduce swelling for trigger finger, carpal tunnel syndrome, or tendinitis.


Tenotomy

A tenotomy is a procedure used to remove tissue from an improperly healed or painful tendon. The tissue removal can help restore function and provide pain relief.
