What are the two associations with upper limb fractures?

Young with high energy injuries

Elderly osteoporotic fractures

What is the most commonly dislocated joint? And why?

Shoulder because the humeral head is substantially larger than the glenoid fossa

Does a shoulder dislocation require imaging?

Yes to rule out fractures

Perfectly

How do you manage a shoulder dislocation?

Muscle relaxants, analgesia, closed reduction, immobilisation, physio

If complicated (e.g. Bankart lesion) - open reduction and internal fixation may be req.

What is a Bankart lesion?

Injury of the anterior glenoid labrum of the shoulder due to anterior shoulder dislocation

What is a subacromial impingement?

Pain and dysfunction from any pathology increasing the volume of the subacromial space/size of its contents

How well did you know this?

Perfectly

What commonly causes subacromial impingement?

Tendon tissue, esp. supraspinatous or soft tissue that is trapped in the joint

How well did you know this?

Perfectly

What symptoms are commonly caused by subacromial impingement?

Pain on movement (esp. overhead activities), nocturnal pain (esp. when lying on shoulder), painful arc

Perfectly

What is painful arc?

Pain related restriction of movement and strength with abduction of arm between 60 and 120 degrees)

How do you treat subacromial impingement?

Subacromial steroid injection, physiotherapy, arthroscopic subacromial depression

What is adhesive capsulitis?

Aka frozen shoulder

Inflammation and fibrosis of the joint capsule leading to contracture of the joint

How do you diagnose adhesive capsulitis?

Clinically

What symptoms are typical of adhesive capsulitis?

Severe restriction and limitation of both active and passive RoM in all plates (esp. external rotation), dull shoulder pain

What will you find on XRay with adhesive capsulitis?

Nothing

What is the management of adhesive capsulitis?

Physiotherapy and NSAIDs
If early presentation, steroid injections can help bring down swelling

Late presentation - surgery

How long does it usually taken for adhesive capsulitis to go away?

1.5-2 years

What are the two types of rotator cuff injury?

Traumatic - acute injury, in athlete, acute severe pain and loss of strength Degenerative - older adults, chronic pain, loss of strength less pronounced

In rotator cuff injury what tendon appears to be most commonly affected?

Supraspinatus

What are the signs of rotator cuff injury?

Superior displacement of the humeral head on XRay

How do you manage rotator cuff injuries?

Acute tear - early surgery | Chronic degenerative - symptomatic - surgery, but treatment mostly conservative

What are the types of arthritis that can affect the shoulder?

OA, inflammatory arthritis, post-traumatic arthritis

What is the most common way to dislocate your elbow?

Fall on outstretched hand

What is the most common type of elbow dislocation?

Posterior

What are the signs and symptoms of an elbow dislocation?

``` Pain, swelling, inability to flex/extend Ekbow deformity (olecranon more prominent posteriorly), limb length discrepancy) ```

What imaging should you do for elbow dislocation?

XRay - confirm dislocation, rule out fractures

How do you manage elbow dislocation?

Simple - analgesia, closed reduction, immobilisation More complex - open reduction, internal fixation

What causes insertional tendinopathies?

Repetitive strain and subsequent poor healing

What is tennis elbow?

Overuse injury of hand and finger extensors that originate in the lateral humeral epicondyle (i.e. from repetitive/excessive pronation/supination and extension of wrist)

What are the clinical features of tennis elbow?

Pain and tenderness over lateral epicondyle and extensor muscles, thickening of tendons

What is golfer's elbow?

Overload injury of the hand and finger flexor tendons that originate in the medial humeral epicondyle(from repeated wrist flexion and pronation)

What are the clinical features of Golfer's elbow?

Pain over medial epicondyle and along flexor muscles, thickening of tendons

What is cubital tunnel syndrome?

Compression of the ulnar nerve at the elbow

What is the aetiology of cubital tunnel syndrome?

Leaning on elbow/prolonged elbow flexion, athletic activities

What are the clinical features of cubital tunnel syndrome?

Sensory loss over hypothenar eminence and medial 1 1/2 fingers +ve tinel test

What is tinel test?

Paraesthesiae reproduced in ulnar portion of hand by tapping medial epicondyle of humerus
