Musculoskeletal nursing is dominated by one recurring theme: circulation distal to the injury. Bones heal slowly and predictably, but the complications that threaten a limb or a life develop in hours. These musculoskeletal nursing study notes cover fracture care, neurovascular assessment, and the postoperative priorities most tested on the NCLEX-RN.
How to use this study guide
Treat the neurovascular check as the spine of this topic. Every device — cast, splint, traction, or prosthesis — creates the same question: is the tissue beyond it still perfused and innervated? Work each section below back to that assessment.
Neurovascular assessment: the six Ps
Assess distal to every injury, cast, or surgical site, and compare with the opposite limb. Pain that is disproportionate to the injury and unrelieved by analgesia is the earliest and most important warning.
- Pain — increasing, unrelieved, worse on passive stretch
- Pallor — colour change distal to the injury
- Pulselessness — a late and ominous sign
- Paraesthesia — tingling or numbness
- Paralysis — loss of movement, a late finding
- Poikilothermia — the limb becomes cool to touch
Compartment syndrome
Pressure within a closed muscle compartment rises until perfusion stops. It is a surgical emergency, and the nursing error that worsens it is elevating the limb above heart level or applying ice, both of which further reduce arterial flow.
- Earliest sign is severe pain unrelieved by opioids and worse on passive stretch
- Do not elevate above heart level; keep the limb at heart level
- Do not apply ice
- Loosen restrictive dressings and notify the provider immediately
- Definitive treatment is fasciotomy
Fractures and immobilisation
- Fat embolism — most common after long bone or pelvic fracture; presents with dyspnoea, confusion, and a petechial rash, usually within 72 hours
- Casts — handle a wet plaster cast with palms; never insert objects to scratch; report hot spots or foul odour
- Traction — weights hang freely and are never removed without an order; maintain alignment
- Skeletal pin sites — monitor for infection; clean per protocol
- Compartment checks — perform on a defined schedule, not only when the patient complains
Joint replacement care
Postoperative care centres on preventing dislocation and venous thromboembolism. Hip precautions in particular are frequently tested as patient-teaching questions.
- Hip precautions — avoid flexion beyond 90 degrees, avoid crossing the legs, avoid internal rotation
- Use an abduction pillow where prescribed and raised toilet seats at home
- Dislocation signs — sudden severe pain, shortening, internal or external rotation of the limb
- Knee replacement — early mobilisation and continuous passive motion where ordered
- Anticoagulation and early ambulation reduce thromboembolism risk
Mobility, safety, and assistive devices
- Cane — held on the strong side; advance the cane with the weak leg
- Crutches — weight rests on the hands, never the axillae, to avoid nerve injury
- Walker — all four points on the floor before stepping forward
- Stairs — up with the good leg first, down with the affected leg first
- Assess the home environment for rugs, cords, and lighting
NCLEX tips: musculoskeletal nursing
- Pain unrelieved by opioids after a fracture is compartment syndrome until proven otherwise.
- Never elevate a limb with suspected compartment syndrome above heart level.
- Petechiae with dyspnoea and confusion after a long bone fracture suggests fat embolism.
- Crutch weight belongs on the hands, not the axillae.
- Hip replacement teaching answers almost always involve avoiding flexion beyond 90 degrees.
Turn this guide into active review
Reading through notes once is recognition, not recall. Convert each section above into questions you answer from memory, then check yourself. The Musculoskeletal Nursing Study Notes Bundle packages this material as condensed, exam-ready PDF notes organised by condition, if you would rather review from a prepared set than build one.
Frequently asked questions: musculoskeletal nursing
What is the earliest sign of compartment syndrome?
Pain that is out of proportion to the injury, unrelieved by analgesia, and worse on passive stretching of the muscle. Pulselessness is a late sign — waiting for it risks permanent damage.
Which side should a cane be held on?
The strong, unaffected side. The cane and the weak leg then move together, widening the base of support and shifting weight away from the affected limb.
What are standard hip replacement precautions?
Avoid hip flexion beyond 90 degrees, avoid crossing the legs or adducting past midline, and avoid internal rotation. These are typically maintained for several weeks per surgeon protocol.
