English for Orthopaedic Nursing: Essential Vocabulary & Phrases

"cortical bone"

The dense, compact outer layer of bone that provides structural strength and protects the inner cancellous bone

"The X-ray confirmed that the fracture had breached the cortical bone on both the medial and lateral aspects of the tibia."

"cancellous bone"

The spongy, porous inner bone tissue with a honeycomb-like structure that contains red bone marrow and is important for haematopoiesis

"The surgeon noted excellent cancellous bone quality at the femoral neck, which improved the predicted hold strength of the prosthesis."

"periosteum"

The dense connective tissue membrane covering the outer surface of bones, except at articular surfaces, containing osteoblasts essential for bone repair

"Preservation of the periosteum during surgery is critical because it supplies the blood flow necessary for fracture healing."

"articular cartilage"

The smooth hyaline cartilage lining the ends of bones within a synovial joint, reducing friction and absorbing shock during movement

"MRI imaging revealed significant loss of articular cartilage in the medial compartment of the knee, consistent with grade III osteoarthritis."

"synovial membrane"

The inner lining of a joint capsule that secretes synovial fluid to lubricate the joint and nourish the articular cartilage

"Biopsy of the inflamed synovial membrane confirmed rheumatoid pannus formation rather than septic arthritis."

"ligament"

A band of dense fibrous connective tissue that connects bone to bone, providing joint stability and limiting excessive movement

"The MRI report described a complete tear of the anterior cruciate ligament with associated bone bruising on the lateral femoral condyle."

"tendon"

A cord of dense fibrous connective tissue that attaches muscle to bone, transmitting the force of muscular contraction to produce joint movement

"bursa"

A small fluid-filled sac lined with synovial membrane that cushions and reduces friction between tendons, muscles, and bony prominences

"The patient presented with swelling and tenderness over the olecranon, and aspiration of the inflamed bursa confirmed non-infectious bursitis."

"comminuted fracture"

A fracture in which the bone is broken into three or more fragments, typically caused by high-energy trauma and often requiring surgical fixation

"The orthopaedic team decided to proceed with open reduction and internal fixation due to the comminuted fracture pattern seen on the CT scan."

"pathological fracture"

A fracture that occurs through bone weakened by an underlying disease process such as osteoporosis, metastatic cancer, or Paget's disease

"stress fracture"

A small crack in bone resulting from repetitive mechanical loading that exceeds the bone's capacity for remodelling, common in athletes and military recruits

"The runner presented with insidious onset tibial pain, and MRI confirmed a stress fracture of the mid-shaft tibia consistent with training overload."

"open fracture"

A fracture in which the broken bone communicates with the external environment through a wound in the overlying skin, carrying a significant risk of infection

"The Gustilo-Anderson classification was used to grade the open fracture and guide the timing of debridement and wound management."

"avulsion fracture"

A fracture in which a fragment of bone is pulled away from its main structure by the forceful contraction of a tendon or ligament attached to that fragment

"The lateral ankle X-ray revealed an avulsion fracture of the fifth metatarsal base caused by the strong pull of the peroneus brevis tendon during inversion."

"impacted fracture"

A fracture in which one bone fragment is driven into another, compressing the cancellous bone and often resulting in a stable but shortened segment

"The impacted fracture of the femoral neck was treated conservatively with protected weight-bearing because the fragments remained well aligned."

"neurovascular compromise"

Impairment of the nerve and blood supply distal to a fracture or injury, manifesting as altered sensation, motor weakness, or absent pulses

"The nurse identified signs of neurovascular compromise in the injured limb and immediately escalated to the surgical team for urgent assessment."

"compartment syndrome"

A surgical emergency in which rising pressure within a closed muscle compartment compromises blood flow, causing ischaemia and potentially irreversible muscle and nerve damage

"The patient's increasing pain on passive stretch, firmness of the lower leg, and escalating analgesia requirements prompted emergency fasciotomy for compartment syndrome."

"open reduction internal fixation"

A surgical procedure in which a fracture is exposed through an incision, the fragments are anatomically realigned, and fixation devices such as plates, screws, or nails are implanted to maintain the reduction

"The trauma team planned open reduction internal fixation for the displaced tibial plateau fracture to restore joint congruity."

"intramedullary nail"

A metal rod inserted into the medullary canal of a long bone to stabilise a fracture, allowing early weight-bearing and mobilisation

"capillary refill time"

The time taken for colour to return to the nail bed after applying blanching pressure, normally less than two seconds, used as an indicator of peripheral perfusion

"A capillary refill time of four seconds in the affected digits prompted urgent orthopaedic review for possible vascular injury."

"range of motion"

The extent of movement possible at a joint, measured in degrees and recorded as active or passive, used to track rehabilitation progress

"At six weeks post total knee replacement, the patient had achieved a range of motion from five degrees extension to 100 degrees flexion."

"visual analogue scale"

A validated pain measurement tool in which patients mark their pain intensity on a 100 mm horizontal line anchored between no pain and worst imaginable pain

"Deep vein thrombosis prophylaxis with low-molecular-weight heparin was commenced six hours post-operatively and continued for 35 days following total hip arthroplasty."

"osteoarthritis"

A degenerative joint disease characterised by progressive loss of articular cartilage, subchondral bone changes, and osteophyte formation, causing pain, stiffness, and functional impairment

"Radiographs of the hip showed the classic triad of osteoarthritis: joint space narrowing, subchondral sclerosis, and marginal osteophytes."

"osteoporosis"

A metabolic bone disease characterised by reduced bone mineral density and deterioration of bone microarchitecture, resulting in increased fragility and fracture risk

"The DEXA scan confirmed severe osteoporosis with a T-score of −2.8, and the rheumatologist commenced bisphosphonate therapy and calcium supplementation."

"osteomyelitis"

"discharge planning"

The coordinated multidisciplinary process of preparing a patient for safe return to the community, addressing equipment, support services, medication, and follow-up arrangements

"Discharge planning for the elderly patient began on the day of admission and involved the surgeon, nursing staff, physiotherapist, occupational therapist, and social worker."

"falls prevention"

A set of evidence-based interventions — including strength and balance training, medication review, and environmental modification — aimed at reducing the risk of falls in at-risk patients

"The nurse completed a falls prevention assessment on admission and implemented bed alarms, non-slip footwear, and regular toileting as risk reduction strategies."

"pressure injury"

Localised damage to skin and underlying soft tissue usually over a bony prominence, caused by prolonged pressure or pressure combined with shear, particularly relevant in immobile orthopaedic patients

"The Waterlow score identified a high pressure injury risk and the care plan included two-hourly repositioning, a pressure-redistributing mattress, and barrier cream."

"functional independence measure"

A validated assessment tool scoring a patient's level of independence across 18 motor and cognitive tasks, used in rehabilitation to track progress and plan discharge
