This section provides a summary of the area of practice for this unit and highlights the importance of this topic to general practice and the role of the GP.

Musculoskeletal conditions include more than 150 different conditions involving bones, ligaments, connective tissue and joints. They represent the most common chronic conditions in Australia, accounting for 13% of the total disease burden.1,2 Musculoskeletal conditions can result from hereditary, congenital or acquired pathologic processes. They can be caused by infectious, inflammatory or degenerative processes; traumatic or developmental events; or neoplastic, vascular or toxic/metabolic diseases.3 Musculoskeletal symptoms affect all age groups and presentation can vary from acute to chronic and simple to complex.1

Low back pain is the most common musculoskeletal condition globally, followed by fractures, osteoarthritis, other injuries, neck pain, amputations and rheumatoid arthritis.4 Back pain and problems, which include disc disorders, sciatica and other conditions which result from injury or degenerative conditions,1 are a large contributor to illness and disability in Australia, accounting for 4.5% of the total disease burden.2 Osteoarthritis is reported to be experienced by one in 11 Australians and is the most common cause of hip and knee replacement in Australia.5 Aboriginal and Torres Strait Islander peoples have a slightly higher incidence of osteoarthritis.5,6

Risk factors for musculoskeletal conditions include age, being overweight or obese, physical inactivity, occupation (involving manual labour or joint loading) and history of joint trauma and injuries.1,7 Chronic musculoskeletal conditions can have a profound impact on quality of life and can result in the limitation of social, community and occupational activities.8,9 They are highly associated with significant mental health decline and deteriorated functioning.4 Musculoskeletal conditions are also highly comorbid, with the majority of people with a chronic musculoskeletal condition having at least one other chronic condition, for example, cardiovascular disease and mental health conditions.1

The prevalence of musculoskeletal conditions increases with age, from 1% among people aged one to 14 to 72% among people aged 75–84.1 Older people with chronic musculoskeletal conditions are generally less active in comparison with those without musculoskeletal conditions. Musculoskeletal conditions can greatly increase older patients’ risk of functional decline and can result in their reduced ability to manage comorbid conditions. They also increase all-cause mortality in people admitted to hospitals.9-11 Very remote areas also have the highest rate of total disease burden due to musculoskeletal conditions.12

General practitioners (GPs) play a crucial role in the prevention of musculoskeletal conditions, including through obesity management to limit osteoarthritis development and educating patients on injury prevention strategies.13 GPs are also well placed to negotiate a management plan to improve and maintain functioning, delay disease progression and facilitate return to work or activity in patients presenting with musculoskeletal conditions. Some GPs will choose to develop extra skills in the area of sports medicine, but all GPs will manage injuries and other conditions incurred as a result of exercise. This is especially so in rural areas where access to other services may be limited. 

For patients with multiple chronic conditions including a musculoskeletal condition, treatment and management can become more complex and require a broader and integrated approach, ranging from interventions like strengthening exercises and stretches, to involvement of other health professionals like physiotherapists, exercise physiologists and rehabilitation physicians. Comorbidities can also make it more difficult for patients to self-manage their conditions. GPs therefore need to facilitate a patient-centred, whole-person care, chronic disease approach. Interdisciplinary teamwork is also an important feature in managing acute and chronic presentations involving musculoskeletal presentations.

This section includes tips related to this unit from experienced GPs. This list is in no way exhaustive but gives you tips to consider applying to your practice.

Extension exercise: Speak to your study group or colleagues to see if they have further tips to add to the list.

  1. When assessing a patient who presents with joint symptoms, history and examination are very important. Having a good understanding of anatomy and biomechanics will often help you identify the issue on history alone. Also, deciding if the condition is inflammatory or non-inflammatory, mono, pauci or polyarticular, symmetrical or asymmetrical will help you narrow down the differential diagnosis.
  2. A limping child with fever is an emergency: septic arthritis must be ruled out.
  3. Groin and thigh pain is usually referred from the hip, and gluteal pain from the lumbar spine.
  4. The majority of sports medicine presentations are chronic overuse-type injuries, often relating to biomechanics or load rather than a specific injury, and often present with non-specific symptoms. These can occur with any amount of exercise and not only in athletes. It is important to address these issues, often with a multidisciplinary approach, as they often discourage people from exercising.
  5. Think of compartment syndrome when a patient is in a cast and complains about pain, despite being on pain killers.
  6. Early intervention of inflammatory joint conditions with disease-modifying anti-rheumatic drugs will prevent and limit permanent joint damage

Instructions

This section has some suggestions for how you can learn this unit. These learning suggestions will help you apply your knowledge to your clinical practice and build your skills and confidence in all of the broader competencies required of a GP.

There are suggestions for activities to do:

  • on your own
  • with a supervisor or other colleague
  • in a small group
  • with a non-medical person, such as a friend or family member.

Within each learning strategy is a hint about how to self-evaluate your learning in this core unit.

On your own

Randomly select 10 patients from your practice database who have been diagnosed with gout. Look for guidelines for managing gout. Compare your management against the guidelines.

  • How many patients were managed according to the guidelines? In patients who were not managed according to the guidelines, identify the reasons why.
  • Do a literature search on the treatment of patients with management uncertainties.

Audit 10 of your patients with a diagnosis of osteoarthritis of the knee joint. Compare their management with the recommended guidelines.

  • How did you manage cases where the diagnosis was uncertain? How did you manage the situation when your management suggestions and the patient’s expectations were different?
  • When your management was different from the recommended guidelines, what were the reasons?

Audit five children who you have seen with growing pains. Read about how to manage growing pains.

  • How will you apply the principles to your practice?
  • Identify areas you are uncertain about. Search for guidelines or commentary on how you would manage these uncertainties.
  • Reflect on the exercise.
With a supervisor

Learn to give a cortisone injection or do a joint aspiration with your supervisor. Read about the indications as well as the limitations and contraindications for these procedures.

  • Discuss the indications and limitations, as well as the contraindications of steroid injections with your supervisor. What are the current recommendations?
  • Observe your supervisor giving the injection or undertaking a joint aspiration. Describe the steps to your supervisor.
  • Select an appropriate patient to undertake either of these procedures on. Ask the patient and your supervisor to give you feedback.
  • Are there any other procedures you would like to learn/practise? Can your supervisor suggest some opportunities for you to learn them?

Prepare a presentation to your supervisor on overuse injuries. This might be a tendinopathy, bursitis, or stress fracture.

  • What are the common overuse injuries? How do they present? How can they be prevented? How can they be managed once they do occur?
  • What allied health or other team members should be involved in management?
  • What are the consequences of overuse injuries?

With your supervisor, role-play a counselling session for a patient recently diagnosed with chronic fatigue syndrome/myalgic encephalomyelitis.

  • Explain the diagnosis of chronic fatigue syndrome. Justify the reasons for making the diagnosis. Explore the patient’s concerns and expectations.
  • How would you create a patient-centred management plan?
  • Ask for feedback from your supervisor and reflect on the session.
In a small group

Have a case discussion about the last case of gout you saw.

  • How did you make the diagnosis? What resources did you use to manage the patient? Was there anything you were uncertain about? How did you manage your uncertainty?
  • Reflect on the discussion.
Plan an education session for your general practice clinical meeting on how to approach an acutely swollen joint in a child.
  • Identify the educational objectives of your teaching session. What teaching methods will you use? Will you use any interactive activities? What resources will you use?
  • Following the session, ask the group for feedback and any suggestions for what else you might have included.
  • Is there anything you learnt from preparing the session or from the group that you will include in your future practice?
Role-play the following scenario with a colleague. A 45-year-old factory worker comes to see you with a twisted ankle from lifting a heavy load at work. Perform an ankle examination. After assessing the injury, you make a provisional diagnosis of a simple ankle sprain.
  • Discuss with your colleagues how to manage the injury.
  • What advice do you give the patient?
  • When might you involve a physiotherapist?
With a friend or family member

Have a discussion with a friend or family member who has osteoarthritis of the knee or hip. How do they rate their pain? How does the problem affect them in their day-to-day life? What impact does it have on their mood? How are they managing the pain? Have they modified their day-to-day life because of their osteoarthritis?

  • How does this activity help your understanding of the impact of osteoarthritis on patients? How can this help you in your approach to communicating with patients with osteoarthritis?

Explain Osgood Schlatter disease to a family member or friend who is an adolescent or who has an adolescent child who plays a field sport like football, soccer or netball.

  • Explain the diagnosis, including when they should be worried about symptoms. Discuss how you would manage it.
  • Ask for feedback on how well they understood your explanation and their thoughts about your management plan.
  • What could you change next time?
