Study Notes

General Principles

The musculoskeletal system examination evaluates the patient's posture, gait, and range of motion.
It involves inspecting and palpating the musculoskeletal system for deformities, swelling, tenderness, crepitus, and muscle atrophy.
Evaluating the patient's posture and gait provides insights into any underlying musculoskeletal issues affecting their movement and stability.
Physical examination findings provide valuable information to aid in the diagnosis and management of various musculoskeletal conditions.

Shoulder Examination

The shoulder examination assesses the function of the rotator cuff, glenohumeral joint, and surrounding muscles.
Common procedures include palpation of the acromioclavicular joint, biceps tendon, and coracoid process.
Range of motion testing is essential to check for limitations in flexion, extension, abduction, adduction, internal rotation, and external rotation.
Evaluating muscle strength helps determine the integrity of the rotator cuff muscles and other muscles around the shoulder joint.
Special tests like the empty can test, drop arm test, and Hawkins test assess potential injuries like rotator cuff tears and impingement.

Elbow Examination

Examination includes inspection for deformities, swelling, and skin changes.
Palpation of the medial and lateral epicondyles, olecranon process, and radial head is crucial.
Assess range of motion for flexion, extension, pronation, and supination.
Muscle strength should be tested for the biceps, triceps, and wrist flexors and extensors.
Special maneuvers like the Tinel's sign and the elbow flexion test help detect compression of the ulnar nerve and lateral epicondylitis.

Hand and Wrist Examination

Inspection includes observing hand position, any deformities, and swelling.
Palpate the carpal bones, tendons, and nerves to assess for tenderness.
Evaluate the range of motion, including flexion, extension, radial deviation, ulnar deviation, and grip strength.
Assess muscle strength of the hand and forearm muscles, specifically the intrinsic hand muscles.
Special tests such as the Phalen's test, Finkelstein's test, and carpal tunnel compression test help identify nerve entrapment issues.

Hip Examination

Examine the hip for any signs of limping, gait abnormalities, or asymmetry.
Palpate the iliac crest, greater trochanter, and ischial tuberosity for tenderness.
Assess range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation.
Muscle strength testing is important to evaluate the hip flexors, extensors, abductors, adductors, and rotators.
Perform special maneuvers like the Trendelenburg test and the Thomas test to investigate hip instability and hip flexor tightness.

Knee Examination

Examine the knee for any signs of swelling, warmth, redness, or deformity.
Palpate the patella, joint line, and tibial tubercle to assess for tenderness.

Metatarsus Adductus (MTA)

Evaluation involves assessing the inward deviation of the forefoot, typically observed at birth or during early infancy.
It can be identified through physical examination, where the foot is assessed for the degree of adduction and the ability to passively correct the deformity.

Risk Factors and Indications for Work Up

Metatarsus adductus is often a benign condition that resolves spontaneously.
No specific workup or imaging is usually required.
However, further evaluation may be recommended if the deformity is severe or if there's suspicion of underlying skeletal abnormalities.

Treatment and Referral

In most cases, metatarsus adductus resolves without intervention by the time the child reaches 2-3 years of age.
Conservative management typically involves stretching exercises and observation.
If the deformity is severe or persistent, referral to an orthopedic specialist may be necessary for further evaluation and possible casting or surgery.

Clubfoot

Evaluation involves assessing the foot position, which includes inversion (turning inward), equinus (pointing downward), and adduction (turning inward).
The severity of the clubfoot is assessed by examining the foot's flexibility and the range of motion.
Palpation and inspection of the foot and ankle for any associated malformations or deformities are crucial.

Risk Factors and Indications for Imaging

Family history of clubfoot increases the risk.
Imaging studies, such as radiographs, are usually obtained to evaluate the bone structures and assess the severity of the deformity.

Treatment

Early treatment is crucial for optimal outcomes and involves a series of casts and corrective shoes to gradually reposition the foot.
Surgery may be considered in severe cases where non-operative treatment fails to achieve satisfactory results.

Complications

Complications of clubfoot treatment include recurrence of the deformity, nerve damage, and poor healing.

Calcaneovalgus Foot
