QSS is a condition where the axillary nerve and the posterior circumflex humeral artery are compressed in the shoulder's quadrilateral space.

Causes can be repetitive overhead activities, trauma, or body structure differences that compress the nerve or artery.

Symptoms can include shoulder pain, weakness when lifting, numbness, and sometimes changes in skin color or temperature.

Diagnosis includes clinical exam, MRI, and EMG/nerve studies to check nerve function.

Athletes in sports with repeated shoulder use, like baseball or swimming, are at increased risk.

Mild cases might get better with rest and physical therapy, but ongoing symptoms may need medical help.

Treatments are rest, physical therapy, NSAIDs for pain relief, and maybe surgery.

Surgery is usually an option if other treatments do not help with symptoms.

Recovery time varies, but patients may need weeks to months for full activity return.

Untreated QSS can lead to permanent muscle weakness and atrophy.

Yes, rest, altering activities, and physical therapy are key non-surgical options.

Therapy builds shoulder muscle strength and flexibility to ease nerve pressure.

NSAIDs are often used to manage pain and inflammation.

Repeated overhead movements, such as in baseball, swimming, or volleyball, may lead to QSS.

Yes, changing activities to limit overhead movements can help reduce symptoms.

QSS is relatively uncommon compared to other shoulder and nerve issues.

MRI helps view the quadrilateral space, but clinical diagnosis remains vital due to variable results.

It usually affects one shoulder, though both can be involved, particularly with systemic issues.

Avoiding overhead activities and adding shoulder-strengthening exercises can assist.

QSS affects both genders, but the occurrence is more about activity level and biomechanics.

Yes, nerve gliding exercises can relieve compression and help with symptoms.

The outlook is generally positive with proper treatment, but recovery may be slower in long-term cases.

Poor techniques in weightlifting can contribute to or worsen QSS due to repeated arm strain.

You might need to modify or take breaks from certain activities, especially those with shoulder use.

See a healthcare professional for evaluation and diagnosis.

Injections may relieve pain but do not fix the structural issue.

It frequently affects young to middle-aged adults doing intense physical activities.

Focus on good sports techniques, muscle strengthening, and flexibility exercises to avoid recurrence.

A brace might offer temporary support but is not a cure for QSS.

Complications can include persistent weakness, limited mobility, and chronic pain. Surgery?
