Care begins with understanding the shoulder

The same symptom can have different causes.

Shoulder pain may involve tendons, muscles, cartilage, ligaments, bone or the joint itself. A careful evaluation helps identify the source of the problem before treatment is selected.

At OSM, your physician will consider your symptoms, examination, imaging when appropriate, activity level and goals. Treatment may include nonsurgical care or surgery depending on the diagnosis and your individual needs.

Identify

Determine which shoulder structures may be contributing to pain, weakness, stiffness or instability.

Consider options

Review appropriate nonsurgical and surgical pathways in the context of your diagnosis, health and goals.

Restore function

Develop a thoughtful plan for recovery and a return toward work, recreation, sport and daily activity.

Shoulder treatment pathways

Care matched to the condition and the patient

Shoulder treatment is individualized. Surgery is one option, not the starting assumption, and is considered when it is appropriate for the diagnosis and the patient.

Nonsurgical care

Many shoulder conditions can be managed without surgery. Recommendations depend on the diagnosis, symptom severity, function and goals.

  • Activity modification
  • Medication guidance
  • Physical therapy and rehabilitation
  • Ultrasound-guided injections
  • Calcific tendonitis lavage
  • Steroid injections when appropriate

Surgical care

When surgery is recommended, your physician will explain the procedure, alternatives and expected rehabilitation considerations for your situation.

  • Shoulder arthroscopy
  • Labral repair and stabilization
  • Rotator cuff repair
  • Biceps tenodesis
  • AC joint reconstruction and fracture fixation
  • Anatomic, reverse and revision shoulder replacement

A consultation does not predetermine a treatment. It is an opportunity to understand the problem, review options and make an informed decision with your physician.

Movement matters differently to everyone.

Shoulder care should reflect how you use your shoulder.

An overhead athlete, a patient with arthritis and someone recovering from a fall may share a symptom but have very different needs. OSM develops an individualized plan around the diagnosis, function, health and activities that matter to each patient.
