Do I typically need a referral to see an Orthopedic Surgeon like Dr. McMahon?

In Ontario, a referral from a family doctor (GP) or another specialist (e.g., sports medicine physician, rheumatologist) is generally required to see an Orthopedic Surgeon like Dr. McMahon for consultations and potential surgical treatments covered by provincial health plans like the Ontario Health Insurance Plan (OHIP). This referral ensures the consultation is appropriate and that Dr. McMahon has the necessary background medical information. If you believe you need an orthopedic surgical assessment, speak with your primary care physician or referring doctor.

What does an Orthopedic Surgeon like Dr. McMahon do?

An Orthopedic Surgeon like Dr. McMahon is a medical doctor (physician) specializing in diagnosing, treating, preventing, and rehabilitating injuries and diseases of the body's musculoskeletal system. This includes bones, joints, ligaments, tendons, muscles, and nerves. They manage conditions such as fractures, arthritis, sports injuries, spinal disorders, and congenital deformities. Orthopedic Surgeons use both surgical (joint replacements, fracture repair, arthroscopy) and non-surgical (medication, injections, bracing, physiotherapy) methods. Their goal is to restore function, alleviate pain, and improve quality of life.

What should I bring to my orthopedic appointment with Dr. McMahon?

Bring your provincial health card (e.g., Ontario Health Insurance Plan (OHIP) card), referral letter, a list of all current medications (including dosage and frequency), copies of relevant medical records, imaging reports AND the actual images if on a CD/USB (X-ray, MRI, CT scans – images are very important for orthopedic review), and any pertinent test results. Wear comfortable clothing allowing easy examination of the affected body part(s) (e.g., shorts for a knee problem). Bring any braces, splints, or assistive devices you use.

Are services provided by an Orthopedic Surgeon like Dr. McMahon covered by provincial health insurance (e.g., Ontario Health Insurance Plan (OHIP))?

Most physician consultations, medically necessary assessments, and approved surgical procedures by a registered Orthopedic Surgeon like Dr. McMahon are typically covered by provincial health plans such as the Ontario Health Insurance Plan (OHIP) in ON, provided you have a valid health card and appropriate referral. Diagnostic imaging ordered is also usually covered. However, some specific items like certain braces, custom orthotics, or advanced biologic injections may not be fully covered or may have associated fees. Inquire with the clinic about potential out-of-pocket costs and check with your private insurance, if any, regarding coverage for adjunctive therapies or devices.

What can I expect at my first orthopedic consultation with Dr. McMahon at the clinic?

Your first visit will involve a comprehensive musculoskeletal assessment. This includes a detailed discussion of your medical history, the specific problem (e.g., pain, injury, loss of function), how it started, what makes it better or worse, and its impact on daily activities and quality of life. Dr. McMahon will review any previous treatments and perform a thorough physical examination. Any prior imaging (X-rays, MRI, CT scans) will be reviewed. Based on this evaluation, Dr. McMahon will discuss their diagnostic impressions, may recommend further investigations if needed, and will outline potential treatment options, both non-surgical and surgical, working with you to establish goals.

How does Dr. McMahon treat broken bones (fractures)?

Orthopedic Surgeons like Dr. McMahon are experts in treating all types of bone fractures. Treatment depends on the type and severity of the fracture, its location, and the patient's overall health. Non-surgical treatment may involve realigning the bone (reduction) and immobilizing it with a cast, splint, or brace. Surgical treatment might be necessary for more complex fractures, open fractures, or fractures unlikely to heal well with casting alone. Surgical options include internal fixation (using plates, screws, rods, or pins) or external fixation (using a frame outside the body connected to pins in the bone). Dr. McMahon will determine the most appropriate treatment.

What is joint replacement surgery, and when might Dr. McMahon recommend it?

Joint replacement surgery, or arthroplasty, is a procedure where damaged or arthritic parts of a joint (like the hip, knee, or shoulder) are removed and replaced with artificial components (prostheses). Dr. McMahon might recommend joint replacement if you have severe joint pain and loss of function, typically due to advanced osteoarthritis, rheumatoid arthritis, or a significant injury, and non-surgical treatments are no longer providing adequate relief. The goal is to reduce pain, improve mobility, and enhance quality of life.

How long is the recovery time after orthopedic surgery with Dr. McMahon?

Recovery time varies greatly depending on the type of surgery, the specific joint or bone involved, the patient's age and overall health, and their adherence to the post-operative rehabilitation plan. Some minor procedures may have a recovery of a few weeks, while major surgeries like total joint replacements can take several months for full recovery. Dr. McMahon will discuss the expected recovery timeline during the pre-operative consultation.
