The document provides an overview of the musculoskeletal system including its components like bones, muscles, joints, ligaments and tendons. It discusses the functions of the musculoskeletal and skeletal systems. It describes the different types of muscles, bones, and joints. The document outlines how to examine the musculoskeletal system through general observation, palpation, and assessment of individual joints like the spine, shoulder, elbow, wrist, hip, knee, ankle and foot. It also lists and describes various pathologic conditions that can affect the musculoskeletal system including congenital diseases, acquired skeletal diseases, and other soft tissue disorders.

2. INTRODUCTION
MUSCULOSKELETAL SYSTEM COMPRISES OF:
1. BONES - SKELETON – AXIAL AND APPENDICULAR
2. MUSCLES
3. JOINTS

BLOOD
 MOVE FOOD THROUGH
DIGESTIVE SYSTEM

SKELETAL SYSTEM:
 SUPPORT
 PROTECTION
 MOVEMENTS
 STORAGE OF MINERALS
 PRODUCTION OF BLOOD

TISSUES
 LOCALISED – EX. GOUT
 DIFFUSE PAIN – OSTEOMALACIA, PAGET’S
DISEASE
 AGGRAVATES AT MOVEMENT - FRACTURES

INFECTION, TUMOR
 PAIN AFTER INJURY
 EPISODIC PAIN
 FLITTING JOINT PAIN
PAIN

14. EXAMINATION CAN BE DONE IN TWO PARTS
1. GENERAL OBSERVATION
2. EXAMINATION OF INDIVIDUAL JOINTS
EXAMINATION
1. GAIT AND POSTURE
2. MOBILITY
3. INDEPENDENCE
4. MUSCLE WASTING – Primarily due to muscle disease
as in Polymyositis and Secondarily due to disuse,
either due to joint pain or nerve root compression or
peripheral neuropathy.
5. LONG BONES
6. FRACTURES
7. JOINTS
8. TENDONS
GENERAL OBSERVATION

15.  BONES:
1. ALTERATION IN SHAPE OR OUTLINE, SHORTENING.
2. DEFORMITY OF CHEST
3. LOCALISED SWELLING OF LONG BONES
EXAMINATION – GENERAL PRINCIPLES

16. EXAMINATION – GENERAL PRINCIPLES
PALPATION
TENDERNESS OF BONES IS FOUND IN LOCAL LESIONS
WHEN THERE IS A DESTRUCTIION, ELEVATION OR
IRRITATION TO PERIOSTEUM AS IN OSTEITIS FIBROSA
CYSTICA, MYELOMATOSIS, INFECTION OF BONES AND
RARELY IN LEUKAEMIA

17. 1. COMMON, PAINFUL AND DISTRESSING.
2. CAN INVOLVE ANY BONE.
3. FRACTURES IN HEALTHY BONES ARE DUE TO
TRAUMA.
4. FRACTURES OF RIBS, VERTEBRAE, SKULL ARE
MOST FREQUENTLY DUE TO COMPLICATIONS OF
BONE DISEASE.
5. MULTIPLE RIB FRACTURES ARE DUE TO FALLS.
6. FRACTURES WITHOUT TRAUMA WHEN A BONE IS
WEAKENED BY DISAESE ARE PATHOLOGICAL
FRACTURES.
7. PRESENTS WITH PAIN, SWELLING AND LOSS OF
MOVEMENT.
FRACTURES

18. LOOK IF IT IS OPEN/CLOSE?
DEFORMITY ( dinner fork deformity in colles’
fracture)
LOCALISED TENDERNESS AND SWELLING
(swelling may be not found if the overlying muscle
mass is large)
CREPITUS (due to abnormal motion of bone
ends)
EVALUATE NERVE SUPPLY TO LIMB DISTAL TO THE
SITE OF FRACTURE (ask to voluntarily move ankle
joint in fracture of femur, if absent, nerve injury
must be suspected)
WHAT TO EXAMINE?

19. INSPECTION:
IMPORTANT TO DECIDE WHETHER IT IS INFLAMMATORY OR
NON-INFLAMATORY.
LOOK FOR SWELLING OR DEFORMITY OF JOINT.
INFLAMMATION ASSOCIATED WITH REDNESS, TENDERNESS
AND WARMTH.
WHETHER THE INVOLVEMENT IS SYMMETRICAL
(RHEUMATOID ARTHRITIS) OR ASYMMETRICAL (PSORIATIC
ARTHROPATHY)
EXAMINATION OF JOINTS:

20. •PALPATION:
•TENDERNESS
•DETERMINE WHETHER THE SWELLING IS DUE TO BONY
ENLARGEMENT, OSTEOPHYTES OR EFFUSION
EXAMINATION OF JOINTS
ASSESSMENT OF TENDERNESS
GRADE - 1 PATIENT SAYS THE JOINT IS TENDER
GRADE - 2 PATIENT WINCES
GRADE - 3 PATIENT WINCES & WITHDRAWS THE
AFFECTED PART
GRADE - 4 PATIENT WILL NOT ALLOW TO TOUCH
THE JOINT

21.  CREPITUS:
 THIS CAN BE FEEL BY
PLACING ONE HAND
OVER THE JOINT WHILE
IT IS MOVED PASSIVELY
WITH OTHER.
(OSTEOARTHRITIS,
CARTILAGINOUS
FRAGMENTS IN THE
JOINT SPACES
 RANGE OF MOVEMENT:
 ESTIMATE THE DEGREE
OF LIMITATION BASED
ON THE COMPARISON
WITH NORMAL SIDE.
 BOTH ACTIVE AND
PASSIVE MOVEMENT
SHOULD BE ASSESED.
 LIMITATION OF
MOVEMENT MAY BE DUE
TO PAIN,
INFLAMMATION,
CONTRACTURES,
MUSCLE
SPASM,EFFUSION, BOMY
OVERGROWTH ETC.
CREPITUS AND RANGE OF MOVEMENT
