Study Notes
Elbow Joint
- Consists of humero-ulnar, humeroradial, proximal radio-ulnar, and distal radio-ulnar joints
- Bony landmarks: medial epicondyle, lateral epicondyle, olecranon, olecranon fossa, head of radius, and head of ulna
- Ligaments: ulnar collateral ligament, radial collateral ligament, and anular ligament
- Muscles acting on the elbow joint:
- Chief flexors: biceps brachii and brachialis
- Assisting flexor: brachioradialis
- Chief extensors: triceps brachii
- Assisting extensor: anconeus
Mobilization Techniques
Humero-Ulnar Glide
- Indications: to improve elbow flexion
- Patient position: side lying, affected side down
- Hand placement: one hand stabilizes humerus, other hand mobilizes ulna radially
- Force direction: radially
Humero-Ulnar Ulnar Glide
- Indications: to improve elbow extension
- Patient position: side lying, affected side down
- Hand placement: one hand stabilizes radius, other hand mobilizes humerus radially
- Force direction: radially
Humeroradial Distraction
- Indications: to improve mobility, flexion or extension
- Patient position: supine, elbow fully extended and supinated
- Hand placement: one hand stabilizes humerus, other hand distracts radius from distal aspect of radius
- Force direction: line of radius
Wrist Joint
- Consists of radiocarpal joint (distal aspect of radius, proximal row of carpal bones)
- Bony landmarks: head of ulna, styloid process of ulna, styloid process of radius, and carpal bones
- Ligaments: ligaments of flexor and extensor muscles
- Joint movement: follows convex rule
- Resting position: neutral position, slight ulnar deviation
Mobilization Techniques
1st Carpometacarpal Joint Ulnar Glide
- Indications: to improve thumb flexion
- Patient position: sitting, hand in mid-line position supported on bed
