MSK Clinical Conditions Flashcards
What are Jefferson’s fractures?
- Jefferson’s fractures are fractures of the anterior and posterior arches of the atlas often due to increased axial load e.g. diving into shallow water
- Typically causes pain but no neurological signs but may damage arteries at base of skull with secondary neurological sequelae e.g. ataxia, Horner’s syndrome
What is a mid-shaft humeral fracture?
- Mid-shaft humeral fractures are fractures within the shaft of the humerus, occuring from FOOSH, which damage the profunda brachii artery and radial nerve
- It presents with wrist drop due to paralysis of the extensor muscles of the wrist and some sensory loss over the dorsum of the hand
What is a Colles’ fracture?
A Colles’ fracture is a distal radius fracture caused by a direct blow to the palmar forearm or falling onto extended wrists leading to dorsal displacement
What is a biceps tendon rupture?
Biceps tendon rupture is the complete rupture of the biceps brachii tendon after the very strong contraction of the muscle and presents with a characteristic Popeye sign on elbow flexion
What is groin strain?
- Groin strain is a condition wherein the proximal part of the adductor muscles in the medial thigh are strained/torn due to explosive movements of extreme stretching
- Treatment involves the RICE protocol (rest, ice, compression, elevation)
What is an elbow dislocation?
- An elbow dislocation is a clinical condition in which the joint surfaces of the elbow are separated and presents with pain, deformity or loss of function
- It is the 2nd most common dislocation and results from FOOSH
What is osteoarthritis (most common form of arthritis)?
- Osteoarthritis is a non-inflammatory form of arthritis which causes synovial joints to become painful and stiff due to ‘wear and tear’
- The articular surfaces wear away, presenting with a narrow joint space and severely painful bone grinding reducing one’s range of movement
What is Erb’s Palsy?
- Erb’s palsy is a condition resulting in the paralysis of the arm caused by injury to the upper brachial plexus (C5-C6)
- It presents with waiter’s tip: affected limb hangs limply, medially rotated by pectoralis major and pronated due to the loss of biceps brachii
What is achilles tendonitis?
Achilles tendonitis is a common condition that occurs when the calcaneal tendon (largest in the body) becomes irritated and inflamed due to continuous intense physical activity
What is a calcaneal tendon rupture?
- An Achilles tendon rupture is a condition which occurs when achilles tendon tears (most commonly injured tendon)
- Rupture can occur while performing actions requiring explosive acceleration, such as pushing off or jumping
What is a traumatic posterior shoulder dislocation?
An posterior shoulder dislocation is a clinical condition in which the humeral head is displaced posteriorly in relation to the glenoid fossa
What is a Smith’s fracture?
A Smith’s fracture is a distal radius fracture caused by a direct blow to the dorsal forearm or falling onto flexed wrists leading to palmar displacement
What is medial elbow tendinopathy?
- Medial elbow tendinopathy (golfer’s elbow) is a degenerative condition / overuse injury predominantly seen in athletes
- It is 10x less common than LET and involves pathology in the common flexor tendon
What is a Pott’s Fracture-Dislocation?
A Pott’s fracture is a term used to describe a bimalleolar (medial & lateral malleoli) or trimalleolar (medial & lateral malleoli, distal tibia) fracture which occurs due to the force eversion of the foot
What is a scaphoid fracture?
- A scaphoid fracture is a fracture of one of the carpal bones, presenting as tenderness over the anatomical snuffbox and often has delayed presentation in X-rays (notable swelling)
- It needs to be reduced quickly and untreated, can lead to avascular necrosis
What is spondylolisthesis?
Spondylolisthesis is a slip forwards of the vertebrae above on the vertebra below due to a fracture in the pars interarticularis
What is arthritis?
- Arthritis is a clinical condition characterised by inflammation and stiffness of a joint
- It presents with pain, swelling and stiffness, erythema and an abnormal gait
What is a proximal intracapsular femur fracture?
- A proximal intracapsular femur fracture is a fracture within the capsule of the hip joint which commonly occurs in the elderly, especially women
- It can damage the femoral circumflex artery, carries a risk of avascular necrosis and presents with the distal femur fragment being pulled upwards and laterally rotated (shortening)
What is the hand of benediction?
- The hand of benediction is a clinical condition which occurs as a result of prolonged compression or injury of the median nerve at the forearm or elbow
- The thenar eminence is wasted, due to atrophy of the thenar muscles and if the patient tries to make a fist, only the little and ring fingers can flex completely
What is lateral elbow tendinopathy?
- Lateral elbow tendinopathy (tennis elbow) is a degenerative condition that can cause significant functional impairment in working-age patients
- It is the commonest cause of elbow pain and involves pathology in the common extensor tendon
What is neurapraxia?
Neurapraxia is the mildest form of nerve injury which results in a temporary physiological block of conduction in the affected axons without loss of axonal continuity
What is long thoracic nerve palsy?
- Long thoracic nerve palsy is a condition characterized by pain and loss of shoulder movement due to damage/injury of the long thoracic nerve
- It presents with winged scapula as the serratus anterior is paralysed and the scapula is no longer held against the ribcage so protrudes out the back
What is anterior cord syndrome?
Anterior cord syndrome is a condition where the anterior spinal cord artery is interrupted due to ischaemia/infarction of the anterior two-thirds of the spinal cord
What is axonotmesis?
Axonotmesis is a nerve injury which involves the loss of continuity of the axons and their myelin sheath, but axonal regeneration is possible without surgical intervention
What is neurotmesis?
Neurotmesis is the most serious form of nerve injury where both nerve and the myelin sheath are divided
What is Dupuytrens contracture?
- Dupuytren’s contracture is a clinical condition where 1/more fingers become permanently bent in a flexed position due to the thickening of the connective tissue in the palm
- It begins as small hard nodules under the skin of the palm then worsens over time until the fingers can no longer be straightened
What is neurogenic claudication?
Neurogenic claudication is a common symptom of lumbar spinal stenosis or inflammation of the spinal nerves involving pain in the legs during motion
What are pelvic bone fractures?
- Pelvic bone fractures are fractures which result from direct trauma to the pelvic bones or indirectly through forces transmitted from the lower limb
- Fractures often occur at the weaker points of the bones (pubic rami, acetabulum, region of sacroiliac joint)
What is pes cavus?
- Pes cavus is a foot condition characterised by an unusually high medial longitudinal arch
- It can appear in early life and become symptomatic with increasing age
