Tests: Drop arm test (Cant raise arm above shoulder). Tx: NSAIDs, PT, Sling support, Ice /heat applications, Surgical repair, Immobilized for 4-6 wee |
Knee injuries and Ligaments | Ligament tears (ACL, MCL, may hear snap, knee swells almost instantly); Menisci injury (C-shaped plates/pads in knee); Patellar dislocation; Acute: Immediate pain, Tearing or popping, Knee “gives out”, Swelling; Treatment: nonsurgical or surgical |
Joint Dislocation | Dislocation (ends of bone are out of place); Subluxation (partial dislocation); Most common sites: shoulder and acromicoclavicular joints; May be congenital, traumatic, or pathologic |
Joint Dislocation | S/S: pain, deformity, ROM. Diagnosis: physical exam, X-ray. Care: Pain relief, Correction of dislocation, Prevention of complications. Treatment: Shoulder (Immobilize several wks, Sling), Hip dislocation (immediate care, Prevent necrosis of head of femur) |
Joint Dislocation Prevention | Avoid alcohol, Stretch/warm-up, Protective gear, Gun Safety |
Repetitive Use Injury (3) | Carpal tunnel syndrome, Bursitis, and Epicondylitis |
Carpal tunnel syndrome | Manifestations: Numbness and tingling of thumb, index finger, lateral ventral surface of middle finger. Interferes with sleep. Relieved by: Massage, Shaking hands and fingers. Weakness: inability to hold items or perform precise activities |
Bursitis | Inflammation of bursa sac (in synovial joints). Manifestations: Joint is tender, hot, red, edematous; pain with flexion or extension |
Epicondylitis | Tennis elbow, golfer’s elbow. Manifestations: tenderness and pain radiating down the dorsal surface of forearm |
Diagnostics, Medications, and Treatments of Repetitive Use Injury | Tests: Hx and Physical, Phalen test (Backs of hand together for 1min, numbness). Meds: NSAIDs, Corticosteroid injections. Tx: Immobilization (Ergonomic evaluations) or Surgery (resect ligament and enlarge carpel tunnel; remove calcium and scar tissue) |
Fracture | Any break in continuity of bone. Result from: Direct blow, Compression, Torsion (twisting), Stress/pathological (related to a disease process) |
14 Fracture Terms (partial) | Closed/simple (skin not broken), Open/compound (skin broken), Complete (Entire bone broken), Incomplete (Only part of bone broken), Oblique (Angle fracture), Spiral (all the way around), Avulsed (bone and other tissue pulled from the point of attachment) |
14 Fracture Terms (partial) | Greenstick (splinters), Communited (Breaks in many pieces), Compressed (Crushed), Impacted (Bone ends are forced into each other, jumping off of things), Depressed (Bone is forced inward), Stable (Not displaced, maintains alignment), Unstable (displaced) |
Fracture Manifestations | May be accompanied by soft tissue injuries involving muscles, arteries, veins, nerves, skin. May be alteration in circulation, sensation, swelling, pain. May be obvious deformity or fracture. May have felt the breakage of bone during the injury event. |
Fracture Healing Phases | Inflammatory phase (Swollen, may bleed; Collagen forms and allows calcium to be deposited). Reparative phase (Callus begins to form; Osteoblast/osteoclast). Remodeling phase (Starts molding back to normal shape; Callus removed) |
Fracture Healing Time | Uncomplicated fracture of arm or foot heals in 6 – 8 weeks. Fractured hip heals in 12 – 16 weeks. |
Compartment Syndrome | Usually within first 48 hours. Cause: Hemorrhage, edema, compression of nerves. S/S: pain, Paresthesias, dec reflexes and tissue perfusion, CAN LOSE LIMB, Pulses may be normal. Tx: split or removal of cast, Fasciotomy (incision into skin). |
Fat Embolism Syndrome (FES) | Fat lodges in pulmonary vascular or peripheral circulation. Often not diagnosed. S/S: Neurologic, Difficulty breathing/Rhonci/rail/ARDS, Thrombocytopenia (Petechial rash chest/axilla/upper arms), Usually 12-72hr after. Prevent by early stab long-bone fx. |
Deep Vein Thrombosis (DVT) | Prevent: Early immobilization of fracture, Early ambulation. Blood thinners, Prophylactic anticoagulation, Antiembolism stocking, Compression boots, Prompt diagnosis of DVT and adequate treatment. S/S: swelling, + Homan’s sign, 5 P's |
Infection of Fracture | Any complication decreasing blood supply increases risk. May result from contamination at time of injury or during surgery. May lead to: Pseudomonas, Staphylococcus or Clostridium, or osteomyelitis (infection of bone) |
Delayed Union | Prolonged healing of bones. Risk Factors: Poor nutrition, Inadequate immobilization, Prolonged reduction time (long time to put back into place), Infection, necrosis, age, Immunosuppression, Severe bone trauma. Detected by serial X-rays. |
Non-Union | Persistent pain and movement at fracture site. Treatments: Surgery (internal fixation, bone grafting), Debridement if infection present, Electrical stimulation, Growth hormone. |
Reflex Sympathetic Dystrophy/Complex regional pain syndrome | Poorly understood post-traumatic condition. Manifestations: persistent pain, hyperesthesias (^ feeling), swelling, changes in skin color, texture, temperature, decreased motion = muscle atrophy. Treatment includes sympathetic nerve block. |
Emergency Care of a Fracture | Immobilization (Try to keep normal anatomical alignment). Maintenance of tissue perfusion (5 P’s). Prevention of infection: Open? Cover with sterile dressing. Worst case… stop bleeding even if it’s not sterile. |
Diagnostic Test for a Fracture | History of incident and initial assessment. X-ray. CBC. Blood chemistries. Coagulation studies. Renal function: Myoglobunuria (Muscle breakdown, myoglobin released = clogs up kidneys). |
Medications for a Fracture | Pain and inflammation control (Opioids/NSAIDs). Medications to guard against ulcers. Stool softeners. Antibiotics. Anticoagulants. |
Treatment for a Fracture | Closed reduction (Cast, splint, traction) or Open reduction (Surgery) |
Traction Acronym | Temperature, Ropes hang freely, Alignment, Circulation check (5 P's), Type and location of fracture, Increase fluid intake, Overhead trapeze, No weights on bed or floor. |
4 Kinds of Traction | Manual, Skin, Balanced Suspension, and Skeletal |
Manual Traction | Physical pulling and realigning |
Skin Traction | AKA: Straight traction. Help control muscle spasms. Immobilize injury before and after surgery. Buck’s traction. |
Balanced Suspension Traction | More than one point of pull |
Skeletal Traction | Pins (clean 2-3/day), ex. halo, cannot be removed by a nurse! |
Casting | Rigid device immobilizes bones and promotes healing. Above/below fracture. Types: Plaster (48hrs to dry), Fiberglass (dries within 1hr). Assess for: Numbness, tingling, 5 P’s, hotspots (may indicate infection). Hairdryer on cool may help itching. |
Fracture Surgery | Direct visualization and repair. External fixator. Internal fixator (Open reduction internal fixation) (ORIF) |
External Fixation | Frame connected to pins inserted into long axis of bone. Maintains immobilization of fracture. Nurse: Clean pin sites with Peroxide and/or Triple antibiotic ointment, 2-3/day. |
Internal Fixation | Surgery. Open reduction internal fixation (ORIF), Involves reducing fracture and applying hardware (pins, nails, screws, or plates) to hold bones in place. Post-op: Hemovac, JP bulb, bowel sounds, PT, occupational therapy, early mobilization, TCDB. |
Electrical Bone Stimulation | Non-healing/slow healing fractures. Invasively or noninvasively. Contraindicated: In presence of infection, Upper extremities fracture in a pacemaker client. |
