Suprascapular Nerve Release

Suprascapular nerve release surgery is a procedure designed to relieve pressure on the suprascapular nerve, which runs through the shoulder and can become entrapped due to various factors like repetitive shoulder movements, trauma, or anatomical abnormalities. The shoulder surgery is usually performed arthroscopically, meaning it’s done using small, key-hole incisions and a camera to guide the procedure.

Candidates for suprascapular nerve release surgery are typically people who have MRI-confirmed suprascapular nerve compression; and who experience persistent shoulder pain, weakness, or limited range of motion due to this nerve entrapment. This surgery is generally recommended for those who have not responded to conservative treatments such as physical therapy, medication, activity modification and/or injections. Athletes and individuals with occupations requiring repetitive shoulder movements may also be candidates if they suffer from suprascapular nerve entrapment.

As with any surgery, suprascapular nerve release carries some risks. These can include infection, bleeding, nerve damage, persistent pain, or incomplete relief of symptoms. There is also a risk of complications related to anaesthesia. It should be noted however, that the procedure is generally considered safe, especially when performed by an experienced orthopaedic surgeon at ASULC.

Recovery after suprascapular nerve release surgery varies but typically takes several weeks to a few months. Full recovery, including a return to normal activities, can take around 3 to 6 months, depending on the severity of the initial condition, the degree of muscle and nerve damage; and a patient’s overall health.

For arthroscopic suprascapular nerve release, patients are placed under general anaesthesia (ie. you are asleep for the procedure). During the procedure, an Adelaide orthopaedic surgeon will make small incisions around the shoulder area to insert a camera and surgical instruments. The camera provides a clear view of the shoulder’s internal structures, allowing the surgeon to carefully release the suprascapular nerve from any compressing structures.

Symptoms of suprascapular nerve entrapment typically include shoulder pain that may radiate to the upper arm or neck; weakness in the shoulder; and functional difficulty with overhead movements. Some people may also experience a dull ache or a sharp, burning sensation. Muscle atrophy such as wasting in the affected shoulder may occur in chronic cases.

Imaging techniques such as MRI or ultrasound may be used to visualise the nerve and surrounding structures. Electromyography (EMG) and nerve conduction studies can also help confirm the diagnosis by evaluating nerve function. Suprascapular nerve entrapment is diagnosed through a combination of patient history, physical examination, and imaging studies (most commonly an MRI).

Compressive lesions of the nerve such as para-labral cysts can recede, leading to improvement in symtoms attributatble to nerve compression. Non-invasive options are often recommended before considering suprascapular nerve release surgery. These can include physical therapy, anti-inflammatory medications, and corticosteroid injections. Lifestyle modifications and ergonomic adjustments may also help alleviate symptoms.

The success rate of suprascapular nerve release surgery is generally high, with many patients experiencing significant pain relief and improved shoulder function. The success rate can vary depending on factors such as the duration and severity of the entrapment; the duration of symptoms; and the patient’s overall health.

The timeline for returning to normal activities varies, but most patients can gradually resume light, restricted activities within a few weeks after surgery. Full return to work, sports, or other strenuous activities may take 2-6 months, depending on the individual’s progress and the demands of their daily activities.

The orthopaedic specialists at Adelaide Shoulder & Upper Limb Clinic are experienced in performing arthroscopic shoulder surgery for shoulder pain and weakness related to suprascapular nerve entrapment.
