Musculoskeletal

Intermaxillary fixation immobilizes a fractured mandible by wiring or elastic banding the jaws together, and the dominant nursing concern throughout is airway. Wire cutters or scissors are kept taped to the head of the bed and travel with the client, and both the client and family are taught their location and use. Suction is immediately available. Positioning is upright or side-lying, never supine, so that secretions and any vomit drain away from the airway. Nausea and vomiting are treated as urgent, with antiemetics given promptly and prophylactically where risk is high, because vomiting behind a fixed jaw is the event that causes aspiration and obstruction. Nutrition is entirely liquid, taken through a straw or syringe, and requires attention to calorie and protein density since intake typically falls; weight is monitored. Oral hygiene is intensive, with frequent rinsing and irrigation, since food debris accumulates and cannot be brushed away normally, and infection risk is high. Communication is affected, so a writing board or device is provided. Clients are taught which wires may be cut in an emergency and instructed to seek help immediately afterwards.

Compartment syndrome occurs when pressure inside a fascial compartment rises above the level at which capillaries perfuse the tissue, most often after fracture, crush injury, burns, or a tight cast or dressing. Muscle and nerve suffer irreversible damage within hours, and the outcome depends on how quickly the pressure is relieved. The earliest and most reliable sign is pain out of proportion to the injury and unrelieved by analgesia, often worsened by passive stretch of the muscles in the compartment, followed by paresthesia, then pallor, paralysis and finally pulselessness — with the last two being late and indicating that damage has already occurred. Because a pulse remains palpable until very late, its presence must never be used to exclude the diagnosis. Management is immediate release of anything constricting, with a cast split or bivalved or a dressing loosened, and fasciotomy where pressure remains raised. The limb is kept at heart level rather than elevated, since elevation reduces arterial inflow and can worsen ischemia once the syndrome is established.

External fixation stabilizes fractures using percutaneous pins or wires fixed to an external frame, and is used for open fractures, comminuted or unstable fractures, significant soft tissue injury, infected fractures and limb lengthening. It permits access to wounds and early mobilization while maintaining alignment. Nursing care centers on the pin sites, which communicate directly with bone: care follows institutional protocol, sites are inspected for redness, swelling, purulent or increasing drainage, odor, pin loosening and increased pain, and occlusive dressings are avoided since trapped moisture promotes infection. Serous drainage in the early period is expected. The frame itself is never adjusted by nursing staff, since altering it changes the reduction; it is used to support and lift the limb when repositioning. Neurovascular assessment distal to the injury continues, because swelling and compartment syndrome remain possible. Elevation reduces swelling, and mobilization proceeds as prescribed. Psychosocial care matters: the device is visually striking, and clients frequently report distress about appearance and about the reactions of others, which is addressed openly rather than left unspoken.

Fat embolism syndrome occurs when fat globules from bone marrow enter the systemic circulation after fracture of long bones, most commonly the femur, or of the pelvis, and also after orthopedic surgery, particularly intramedullary nailing and joint replacement. Onset is typically twenty-four to seventy-two hours after injury. The classic triad is respiratory — dyspnea, tachypnea, hypoxemia progressing toward acute respiratory distress syndrome; neurological — confusion, restlessness, agitation, and in severe cases seizures or coma; and dermatological — a petechial rash over the chest, axillae, neck, shoulders and conjunctivae, which appears in a minority of cases but is close to pathognomonic when present. Fever and tachycardia are common. Diagnosis is clinical, since no single test confirms it, and management is supportive: oxygen, ventilatory support where required, fluid balance and hemodynamic support. Prevention rests on early fracture stabilization and careful handling. The main differential is pulmonary embolism, which lacks the rash and usually occurs later, and the neurological features distinguish it from compartment syndrome, which is confined to the limb.

The epiphyseal plate is the site of longitudinal bone growth and the weakest part of a growing bone.

Hip fracture in older adults is usually a fragility fracture, occurring on a background of osteoporosis after a low-energy fall, and it carries substantial morbidity and mortality — a large share of clients never return to their previous level of independence. Fractures are classified by location relative to the joint capsule: intracapsular fractures of the femoral neck threaten the blood supply to the femoral head and risk avascular necrosis, while extracapsular intertrochanteric and subtrochanteric fractures lie outside it and bleed more. The classic presentation is groin or hip pain, inability to bear weight, and a limb that is externally rotated and shortened by muscle spasm. Because the femur is highly vascular, blood loss can be significant, so vital signs matter alongside the limb assessment. Management is usually surgical and early, because prolonged immobility brings pneumonia, thromboembolism, pressure injury and delirium — the complications that cause most of the harm.

Traction applies a pulling force to maintain alignment, reduce a fracture, relieve muscle spasm or correct deformity. Skin traction applies force through the skin using adhesive strips or a boot and is temporary and lighter; skeletal traction applies force directly to bone through a pin or wire and permits heavier, longer-term pull. Skeletal traction is never interrupted, since releasing it allows muscle spasm and fracture displacement, whereas skin traction may sometimes be released for care if specifically prescribed. Nursing care covers continuous unimpeded pull, with weights hanging freely, ropes running in the pulley grooves, and knots clear of the pulleys; maintenance of body alignment with the client centered and the counter-traction of body weight preserved; regular neurovascular assessment distal to the injury; pin site inspection and care for signs of infection including redness, purulent drainage, odor, loosening or increased pain, since infection can progress to osteomyelitis; and prevention of the complications of immobility — pressure injury at the sacrum, heels and elbows, constipation, respiratory compromise, and thromboembolism. For a child, developmental and play needs are addressed alongside the physical care.

Assessment precedes movement after a fall, because moving the client is what converts an injury into a worse one. Level of consciousness is checked first, since it reveals whether consciousness was lost or the head was struck, followed by assessment for pain, deformity, shortening or rotation of a limb, and neurological deficit. Only when it is clear what is injured can the method of moving the client be chosen. Vital signs, notification of the provider and family, documentation in the clinical record and an incident report all follow the client's care rather than preceding it.

Osteoarthritis stiffness responds to heat and movement, which is the reverse of the approach used for acute inflammatory injury. Heat increases tissue extensibility and local blood flow, so applying warmth and performing gentle range-of-motion work before weight-bearing eases the morning stiffness characteristic of the condition — typically lasting under 30 minutes, unlike the prolonged stiffness of rheumatoid arthritis. Movement maintains cartilage nutrition and joint function, while immobility increases stiffness and risks contracture. Cold is reserved for acute inflammation and injury, and weight reduction and low-impact exercise are the mainstays of long-term management.

Delegation transfers the performance of a task, never the accountability for it, and never the nursing process. The five rights of delegation are the right task, the right circumstance, the right person, the right direction and communication, and the right supervision. A task is delegable when it is routine, has a predictable outcome, carries little risk, and requires no assessment, teaching, evaluation or clinical judgment. Whether an assistant is capable of the physical act is not the test; whether the act contains a nursing decision is.

Total hip arthroplasty replaces the femoral head and acetabulum, and the early postoperative priority is preventing dislocation while the soft tissues heal. Precautions depend on the surgical approach: the posterior approach, still common, prohibits flexion beyond ninety degrees, adduction past midline and internal rotation, while an anterior approach restricts extension and external rotation instead — so instructions follow the operative note rather than a single rule. Practical measures include raised firm seating and a raised toilet seat, an abduction pillow in bed, avoiding crossing the legs, using a long-handled reacher, sock aid and long-handled sponge to avoid bending, and placing a pillow between the knees when turning. Dislocation presents with sudden severe pain, a shortened and externally rotated limb, and inability to bear weight, and requires immediate reporting. Other priorities are thromboembolism prevention through early mobilization, compression and prophylactic anticoagulation; infection prevention, with dental and other procedures later requiring prophylaxis in some clients; neurovascular assessment of the limb; and pain control adequate to permit the physiotherapy that determines the functional outcome.

Scoliosis is a lateral curvature with rotation of the spine, and it shows as asymmetry of shoulders, scapulae, ribs and hips rather than as pain. Management follows the degree of curve: observation for mild curves, bracing in the moderate range to slow progression, and surgical correction with fusion and instrumentation once the curve is severe. Surgery is long, involves significant blood loss, and needs transfusion planning in advance. Postoperative care is built around early mobilization, not immobility, because prolonged bedrest brings pneumonia, thromboembolism, deconditioning and pressure injury. Logrolling protects the fusion when changing position in bed. Pain is intense at first and typically managed with patient-controlled analgesia, with the specific teaching that nobody but the client presses the button — a family member dosing on the client's behalf removes the safety mechanism the pump depends on.

Safe patient handling is determined by the client's weight-bearing ability and size, not by the technique or willingness of the staff. A client who cannot bear weight contributes nothing to the transfer, so the entire load is external, and beyond a modest limit no combination of helpers and posture brings that within safe manual boundaries. Mechanical lifts, slide sheets, lateral transfer boards and sit-to-stand aids exist because manual lifting causes both staff back injury and client shear injury, skin tears and shoulder trauma. A transfer belt assists a client who can bear partial weight; it is not a lifting device.

Rheumatoid arthritis is a systemic autoimmune disease in which synovial inflammation causes progressive joint destruction. It presents symmetrically in the small joints of the hands and feet, characteristically the metacarpophalangeal, proximal interphalangeal and metatarsophalangeal joints while sparing the distal interphalangeal joints, with warm, swollen, boggy joints, morning stiffness lasting more than an hour and easing with gentle movement, and systemic features including fatigue, low-grade fever, weight loss and anemia of chronic disease. Extra-articular involvement includes rheumatoid nodules, pulmonary, cardiac, ocular and vascular disease. Deformities such as ulnar deviation, swan-neck and boutonnière develop with progression. Management aims at early disease-modifying therapy — methotrexate and biologic agents — to prevent joint damage, with corticosteroids and non-steroidal anti-inflammatories for symptom control, alongside physical and occupational therapy, joint protection, energy conservation, and heat for stiffness with cold for acute inflammation. Osteoarthritis by contrast is degenerative, asymmetrical, affects weight-bearing joints and the distal interphalangeal joints, produces brief morning stiffness, worsens with activity, and lacks systemic features.

Antiembolic stockings and casts both constrict when applied incorrectly, and unrelieved pain in a casted limb signals compartment syndrome.

Intermaxillary fixation immobilizes a fractured mandible by wiring or elastic banding the jaws together, and the dominant nursing concern throughout is airway. Wire cutters or scissors are kept taped to the head of the bed and travel with the client, and both the client and family are taught their location and use. Suction is immediately available. Positioning is upright or side-lying, never supine, so that secretions and any vomit drain away from the airway. Nausea and vomiting are treated as urgent, with antiemetics given promptly and prophylactically where risk is high, because vomiting behind a fixed jaw is the event that causes aspiration and obstruction. Nutrition is entirely liquid, taken through a straw or syringe, and requires attention to calorie and protein density since intake typically falls; weight is monitored. Oral hygiene is intensive, with frequent rinsing and irrigation, since food debris accumulates and cannot be brushed away normally, and infection risk is high. Communication is affected, so a writing board or device is provided. Clients are taught which wires may be cut in an emergency and instructed to seek help immediately afterwards.
