Examination of the upper limb

The capsular pattern is a set pattern of loss of motion for each joint. It indicates that there is some degree of joint capsulitis caused by degeneration, inflammation or trauma. There may be a hard end feel in advanced capsulitis

Shoulder tests
Active flexion above head	Resisted abduction
Passive flexion with overpressure	Resisted lateral rotation
Active abduction to ear for painful arc	Resisted medial rotation
Passive lateral rotation	Resisted elbow flexion
Passive abduction	Resisted elbow extension
Passive medial rotation	Resisted adduction
Impingement/lag/stability/proprioception tests
Shoulder capsular pattern: most loss of lateral rotation, less of abduction, least of medial rotation
Elbow tests
Passive flexion	Resisted flexion
Passive extension	Resisted extension
Passive pronation	Resisted pronation
Passive supination	Resisted supination
	Resisted wrist flexion
	Resisted wrist extension
Elbow capsular pattern: more loss of flexion than extension
Wrist tests
Passive pronation	Resisted extension
Passive supination	Resisted flexion
Passive extension	Resisted radial deviation
Passive flexion	Resisted ulnar deviation
Passive radial deviation
Passive ulnar deviation
Wrist capsular pattern: equal loss of flexion and extension
Finger tests

Finger capsular patterns: Loss of:
Thumb: extension & abduction

Glenohumeral joint

Acute or chronic capsulitis – ‘frozen shoulder’

Equipment

Anatomy

The shoulder joint is surrounded by a large capsule and the easiest and least painful approach is posteriorly, where there are no major blood vessels or nerves. An imaginary oblique line running anteriorly from the posterior angle of the acromion to the coracoid process passes through the shoulder joint. The needle follows this line, passing through deltoid, infraspinatus and posterior capsule. The end point should be the sticky feel of cartilage on the head of the humerus or the glenoid.

Comments

The less the radiation of pain and the earlier the joint is treated, the more dramatic is the relief of symptoms. If there is resistance to the injection, the needle has probably been inserted too laterally and must be repositioned more medially. Occasionally there is slight resistance when the needle passes through the capsule. Usually one injection suffices in the early stages of the condition, but if necessary more can safely be given at increasing intervals of a week, 10 days, 2 weeks, etc.; it is sometimes necessary in advanced capsulitis to give four to six injections over about 2 months. Advise the patient that a repeat dose might be needed if the symptoms are severe and gradually return as the effect of the drug wears off.

Alternative approaches

Rarely the posterior approach is not effective, so an anterior approach is used. In this case, the arm is held in slight lateral rotation and the needle inserted on the anterior surface between the coracoid process and the lesser tuberosity of the humerus, and aimed posteromedially towards the spine of the scapula. The same dose and volume is used. The disadvantages to this approach are that the patient can see the needle advancing, the flexor skin surfaces are more sensitive and there are more neurovascular structures lying on the anterior aspect of the shoulder.

Adcortyl (10 mg/ml) can be used for this injection, especially in large shoulders where more volume is required; the dose would then be 4 ml of Adcortyl with 4 ml of 1% local anaesthetic. Smaller patients may require only 30 mg of corticosteroid.

Aftercare

Patient maintains mobility with pendular and stretching exercises within the pain-free range, progressing to stronger stretching when pain is reduced. Strong passive stretching of the capsule can be given when the pain has abated. A strengthening and stabilizing programme is often required, together with postural correction.

Acromioclavicular joint

Acute or chronic capsulitis

Equipment

Anatomy

The acromioclavicular joint line runs in the sagittal plane about a thumb’s width medial to the lateral edge of the acromion. The joint plane runs obliquely medially from superior to inferior and usually contains a small meniscus. Often a small step can be palpated where the acromion abuts against the clavicle, or a small V-shaped gap felt at the anterior joint margin. Passively gliding the acromion downwards on the clavicle may help in finding the joint line.

Comments

Occasionally the joint is difficult to enter; it is normally a narrow space and degenerative changes make it more so. Traction on the arm can open up the joint space and peppering of the capsule with the solution will anaesthetize it while feeling for the joint space with the needle. This will avoid giving unnecessary pain.

Alternative approach

The joint can also be injected anteriorly and horizontally at the V-shaped gap if the superior approach is difficult. The unstable or repeatedly subluxing joint can be helped by sclerosing injections or possibly surgery.

Aftercare

The patient should rest the shoulder for a week then begin gentle mobilizing exercises. Acutely inflamed joints are helped by the application of ice, taping across the joint to stabilize it and by oral pain killers.

Sternoclavicular joint

Acute or chronic capsulitis

Equipment

Anatomy

The sternoclavicular joint contains a small meniscus that can sometimes be damaged and then give painful symptoms. The joint line runs obliquely laterally from superior to inferior and can be identified by palpating the joint medial to the end of the clavicle while the patient protracts and retracts the shoulder.

Technique

• Patient sits supported with arm in slight lateral rotation

• Identify mid-point of joint line

• Insert needle perpendicularly through joint capsule

• Inject solution as a bolus

Comments

Although not a common lesion, this usually responds well to one infiltration.

Aftercare

Rest for a week followed by mobilization and a progressive postural and exercise regimen. Taping the joint helps stabilize it in the acute stage after trauma.
