MUSCULOSKELETAL SYSTEM
Review of Anatomy & Physiology The musculoskeletal system consists of the:
MusclesTendonsLigamentsBonesJointsCartilagesBursae
Primary function: to produce skeletal movements
Functions of the musculoskeletal system: 1. Provides protection for the vital organs including the brain,
heart and lungs.2. Provides a sturdy framework to support body structures.3. Makes mobility possible.4. Joints hold the bones together and allow the body to move.5. Muscles attached to the skeleton contract, moving the
bones and producing heat that helps maintain body temperature.
6. Serves as reservoir for immature blood cells and essential minerals, including:
Calcium – 98% of total body Calcium is present in bone.PhosphorusMagnesiumFluoride
Hematopoiesis A process in which the red bone marrow located within bone
cavities produces red blood cells, white blood cells, and platelets. The formation of blood cellular components.
MUSCLES
1
Characteristic of Muscles: Muscles are made up of bundles of muscle fibers.
Functions: Provide the force to move bones.Assist in maintaining posture.Assist with heat production.
Process of contraction and relaxation: Muscle contraction and relaxation require large amounts of Adenosine Triphosphate.Contraction also requires Calcium, which functions as a catalyst.Acetylcholine released by the motor end plate of the motor neuron initiates an action potential.Acetylcholine then is destroyed by acetylcholinesterase.Calcium is required to contract muscle fibers and acts as catalyst for the enzyme needed for the sliding together action of actin and myosin.Following contraction, Adenosine Triphosphate transports Calcium out to allow actin and myosin to separate and allow the muscle to relax.
Three types of muscles exist in the body:1. Skeletal Muscles – voluntary and striated2. Cardiac Muscles – involuntary and striated3. Smooth / Visceral Muscles – involuntary and non-striated
TENDONS Bands of fibrous connective tissue that lie bones to muscles
LIGAMENTS Strong, dense and flexible bands of fibrous tissue connecting
bones to another bone. Ligaments hold bone and joint in the correct position.
BONES Variously classified according to shape, location and size. Bones are constructed cancellous (trabecular) or cortical
(compact) bone tissue.
Characteristics of Bones: Bones support and protect the structures of the body.
2
Bones provide attachment for muscles, tendons and ligaments.Bones contain tissue in the central cavities, which aids in the formation of blood cells.Bones assist in regulating Calcium and Phosphate concentrations.
Bone Growth: The length of bone growth results from the ossification of the epiphyseal cartilage at the ends of the bones.Bone growth stops between the ages of 18 and 25 year.The width of the bone growth results from the activity of the osteoblasts (bone forming cell) and occurs throughout life but slows down with aging.As aging occurs, osteoclasts (bone resorption) accelerates, decreasing bone mass and predisposing the client to injury.
Functions: LocomotionProtectionSupport and leverBlood productionMineral deposition / storage
Bone is composed of: CellsProtein matrixMineral deposits
Three basic types of bone cell: 1. Osteoblasts
Bone forming cell.Function in the bone formation by secreting bone matrix.
Matrix consists of: a. Collagen fibersb. Ground substances (glycoprotein &
proteoglycans)Minerals deposited in the matrix are Calcium and Phosphorus.
2. Osteocytes Mature bone cell.Involved in bone maintenance.
3. Osteoclasts
3
Bone resorption cell.Involved in dissolving and resorbing bone.
Bone formation: Osteogenesis (bone formation) begins long before birth. Ossification is a process by which the bone matrix
(collagen fibers and ground substances) is formed and hard mineral crystals (Calcium and Phosphorus) are bound to the collagen fibers.
The Skeletal System The adult body has 206 bones.
Axial 1. Head - 22
Cranial bone – 8Facial bone - 14
2. Breastbone / sternum - 13. Ribs – 24
True ribs – 7 pairs (14); joined directly to the sternum.
False ribs – 3 pairs (9); joined to the sternum by cartilage.
Floating ribs – 2 pairs; not connected to the sternum at all, connected to the diaphragm.
4. Spine / Vertebrae - 33Cervical vertebrae – 7Thoracic vertebrae – 12Lumbar vertebrae – 5Sacrum – 5Coccyx – 4
Appendicular Upper extremities
1. Collar bone / clavicle – 22. Shoulder blade / scapula – 23. Humerus – 24. Radius, ulna / forearms – 45. Carpals (8): scaphoid, lunate, triquetrum, pisiform,
trapezium, trapezoid, capitate, hamate
Metacarpals (5)
4
Phalanges (14) each handHands – 54
Lower extremities 1. Hip bone / Ilium – 22. Femur – 23. Kneecap / patella - 24. Tibia, fibula / legs – 45. Tarsals (7): calcaneus, talus, navicular bone, medial
cuneiform bone, intermediate cuneiform bone, lateral cuneiform bone, cuboidal bone
Metatarsals (5) Phalanges (14) each foot Feet - 52
Four categories of bones: 1. Long bones
Shaped like rods or shafts with rounded ends.Designed for weight bearing and movements.A typical long bone has a shaft (diaphysis) primarily cortical bone, proximal and distal diaphysis.Diaphysis is a hollow cylinder of compact bone that surrounds the medullary cavity.Epiphyses are the ends of long bones, are primarily cancellous bones.piphyseal plate separates the epiphyses from the diaphysis and is the center for longitudinal growth in children.Bone growth stops between the ages of 18 and 25 years.Articular cartilage covers the ends of long bones at the joints.
Humerus – “funny bone”; upper arm bone.Radius – outer and shorter bone of the forearm; aligned
to your thumb.Ulna – inner and longer bone of the forearm; aligned to
your pinky.Femur – “thigh bone”; strongest, largest and longest
bone in the body.Tibia – “shin bone”; inner and larger bone of the leg;
connects to the femur to form the knee joint and with the foot bone (talus) to allow the ankle to flex and extend.
Fibula – outer bone of the leg; serves as an area of muscle attachment.
5
Metatarsals – bones of the feet.Metacarpals – bones of the palms or hands.Phalanges – finger and toes bones.
2. Short bones Consist of cancellous bone covered by a layer of compact bone.
Carpals – wrist bonesTarsals – ankle bones
3. Flat bones Are important sites of Hematopoiesis and frequently provide vital organ protection.Made of cancellous bone layered between compact bones.
Ribs – bones that form a protective cage around the organs of the upper body.
Sternum / Breastbone (manubrium, body, xiphoid process) – bones located in the middle of the chest.
Cranium (frontal, parietal, temporal, occipital, sphenoid, ethmoid) – bones protecting the brain.
Scapula – shoulder bladesPortions of the pelvic girdle / hip girdle
4. Irregular bones ave unique shapes related to their function.
Vertebrae of ear ossicles (hammer, anvil, stirrup)Facial bones (turbinate, lacrimal, mandible, maxilla,
nasal, palatine, vomer, zygomatic) Pelvis
JOINTS The part of the skeleton where 2 or more bones are connected.
Characteristics of the Joints: Joints allow the movement between bones.Joints are formed when 2 bones join.Joint surfaces are covered with cartilage.
6
Joints are enclosed in a capsule.Joint contains a cavity filled with synovial fluid.Ligaments hold the bone and joint in the correct position.Articulation is the meeting point of 2 or more bones.
Synovial fluid Is found in the joint capsule.Formed by a synovial membrane which lines the joint capsule.Lubricates the cartilage.Provides a cushion against shocks.
Different types of joints: 1. Amphiarthrosis
Cartilaginous and slightly movable joints.Ex. symphysis pubis
2. Condyloid Freely movable joints.They allow frictionless, painless movements.Ex. wrists
3. Diarthrosis Synovial jointsBall and socket jointsEx. hips, elbows
4. Synarthrosis Fibrous or fixed joints.No movement associated with these joints.
CARTILAGES A dense connective tissue that consists of fibers embedded in a
strong gel-like substance.
BURSAE A sac connecting fluid that is located around the joints to prevent
friction.
ASSESSMENT OF THE MUSCULOSKELETAL SYSTEM

The nurse usually evaluates this small part of the over-all assessment and concentrates on the:
patient’s posturebody symmetrygaitmuscle and joint function
NURSING ASSESSMENT1. Health History
PainBone – dull, deep ache “boring in nature.Function – sharp and piercing, relieved by immobility.Muscle - soreness
ParesthesiaBurning, tingling sensation or numbness
DietHigh purine diet
Family HistoryAllergy
2. Physical Examination Posture
Kyphosis – outward curvature of the spine.Lordosis – inward curvature of the spine.Scoliosis – lateral curvature of the spine.
GaitSmoothness and rhythm
Shuffling gait - characterized by short steps, with feet barely leaving the ground, producing an audible shuffling noise.Ataxic gait – unsteady, uncoordinated walk with a wide base of support and the feet thrown outward.Festinating gait - walks on the toes as if being pushed. Steps start slowly and increase in speed. The upper part of the body advances ahead of the lower part.Antalgic gait – consists of a limp adopted so as to avoid pain on weight-bearing structures (as in hip, knee, or ankle injuries)

RISKS ASSOCIATED WITH MUSCULOSKELETAL DISORDERS:Autoimmune disordersCalcium deficiencyDegenerative conditionsFallsHyperuricemia (excess of uric acid in the blood)InfectionMedications Metabolic disorders (Ex. diabetes, malnutrition, obesity)Neoplastic disorders (Ex. tumors)ObesityPost-menopausal statesTrauma and injury
Nursing Management of Common Musculoskeletal Problems
1. Pain These can be related to joint inflammation, traction, surgical intervention.
a. Assess patient’s perception of pain.b. Instruct patient alternative pain management like
mediation, heat and cold application. Transcutaneous Electrical Nerve Stimulation (TENS) and guided imagery.
TENS - a technique used to relieve pain in an injured or diseased part of the body in which electrodes applied to the skin deliver intermittent stimulation to surface nerves and block the transmission of pain signals.
c. Administer analgesics as prescribed.Usually NSAIDS.Meperidine can be given for severe pain.
d. Assess the effectiveness of pain measures.
2. Impaired Physical Mobility a. Instruct patient to perform ROM exercises, either passive
or active.b. Provide support in ambulation with assistive devices.c. Turn and change position every 2 hours.
11
d. Encourage mobility for a short period and provide positive reinforcements for small accomplishments.
3. Self-Care Deficits a. Assess functional levels of the patient.b. Provide support for feeding problems.
Place patient in Fowler’s position.Provide assistive devices and supervise mealtime.Offer finger foods that can be handled by patient.Keep suction equipment ready.
c. Assist patient with difficulty bathing and hygiene.d. Assist with bath only when patient has difficulty.e. Provide ample time for patient to finish activity.

METABOLIC BONE DISORDERS
OSTEOPOROSIS A disease of the bone characterized by a decrease in the bone
mass and density with a change in bone structure.
Pathophysiology:
Normal homeostatic bone turnover is altered
Rate of bone resorption is greater than bone formation
Reduction in total bone mass
Reduction in bone mineral density
Prone to fracture
Types of Osteoporosis:1. Primary Osteoporosis – advanced age, post-menopausal2. Secondary Osteoporosis – steroid overuse, renal failure
Risk Factors for the Development of Osteoporosis:1. Sedentary lifestyle2. Age – 50 years old and above3. Diet – caffeine, alcohol, low Ca and Vit D4. Post-menopausal – estrogen deficiency5. Genetics – Caucasian and Asian6. Immobility7. Female – due to lower peak bone mass8. Tobacco use
13
9. Low body weight – less than 70 kgs.10. Medications – especially glucocorticoids
Assessment Findings:1. Low stature – decreasing height (10-15 cm) due to
collapsing vertebrae. 2. Bone pain – back pain (T5-L5)3. Dowager’s hump – curved upper back4. Fracture – femur
Laboratory Findings:1. DXA
Most commonly used bone mineral density (BMD) screening.
T-score is at least 2.5 SD below the young adult mean value.
2. X-ray studies
Management of Osteoporosis:1. Diet therapy with Calcium and Vitamin D.2. Food supplementation – Phytoestrogen
BeansCabbageRiceBerriesSesame seedsGrains
3. Hormone replacement therapy.
4. Biphosphonates Alendronate, Residronate – increased bone mass
by inhibiting the osteoclast. These medications are best taken with full glass
of H2O after rising in the morning. The client should remain upright for 30 minutes
after taking the medication to prevent GI side effects especially esophageal irritation.
The client should not drink anything for 30 minutes following administration of the medication to increase absorption of the drug.
5. Moderate weight-bearing exercises.At least 30 minutes, 5 days a week, then work up to 60 minutes.This increases bone mass and total body Calcium.
14
6. Management of fractures.7. Avoid use of tobacco and alcohol.
Osteoporosis Nursing Interventions:1. Promote understanding of osteoporosis and the
treatment regimen.Provide adequate dietary supplement of Calcium and Vitamin D.Instruct to employ a regular program of moderate exercises and physical activity.Manage the constipating side effect of Calcium supplements.Take Calcium supplements with meals.Take Alendronate with an EMPTY stomach with full glass of water.Instruct on intake of hormonal replacement.
2. Relieve the pain. Instruct the patient to rest on a firm mattress.
Suggest that knee flexion will cause relaxation of the back muscle.Heat application may provide comfort.Encourage good posture and body mechanics.Instruct to avoid lifting and heavy lifting.
3. Improve bowel elimination.Constipation is a problem of Calcium supplements and immobility.Advise intake of HIGH fiber diet and increased fluids.
4. Prevent injury.Instruct to use isometric exercise to strengthen the trunk muscles.AVOID sudden jarring, bending and strenuous lifting.Provide a safe environment.

An inflammatory disease
Factors: Genetic → Auto-immune connective tissue
disorders: Fatigue, emotional stress, cold, infection
Cause: Unknown
Pathophysiology: Immune reaction in the synovium → attracts neutrophils →
releases enzymes → brea kdown of collagen → irritates the synovial lining → causing synovial inflammation edema and pannus → formation and joint erosions and swelling
Assessment Findings: PAIN Joint swelling and stiffness- SYMETRICAL, Bilateral Warmth, erythema and lack of function → due to
inflammation SYSTEMIC MANIFESTATION: Fever, weight loss, anemia,
fatigue Palpation of joint reveals spongy tissue Hesitancy in joint movement
Joint Involvement: Joint involvement is SYMMETRICAL AND BILATERAL
characteristically beginning in the hands, wrist and feet Joint STIFFNESS occurs early morning; lasts more than 30
minutes bit relieved by movement diminished as the day progresses.

positioning Maintain adequate hydration and electrolyte balance
Early Complication: Compartment Syndrome
Assessment Findings:1. Pain-Deep, throbbing and UNRELIEVED pain by
opiods Pain is due to reduction in the size of the muscle
compartment by tight cast Pain is due t increased mass in the compartment by
edema, swelling or hemorrhage
2. Paresthesia- burning or tingling sensation3. Numbness4. Motor weakness5. Pulselessness, impaired capillary refill time and cyanotic
