Orthopaedics Flashcards
Risk factors for Achilles’ tendon disorders
Cirpofloxacin
Hypercholesterolaemia
Features of tendinitis
Gradual onset of posterior heel pain following activity
Morning pain and stiffness
Management of tendinitis
Conservative- orthotics, rest, physiotherapy, ice
Medical- analgesia
Specialist- Extracorporeal shock-wave therapy (ESWT), possibly surgery, to remove nodules and adhesions or alter the tendon, may be used where other treatments fail
NB- not steroid injections
Investigate a suspected Achilles’ tendon rupture
Simmonds triad- palpation of snapped tendon, dorsiflexed angle of declination at rest, calf squeeze (no plantar flexion)
Other feratures;
Weakness of plantar flexion of the ankle (dorsiflexion is unaffected)
Unable to stand on tiptoes on the affected leg alone
USS
Referral to orthopaedics
Treatment
Conservative- Rest and immobilisation, Ice, Elevation, ankle boot
Medical- Analgesia
Surgical- repair
Features of adhesive capsulitis (frozen shoulder)
Shoulder pain
External rotation is more affected than internal rotation or abduction
Active and passive movements affected
Painful freezing phase, adhesive phase, recovery phase
Bilateral in 20%
Episode typically lasts between 6 months-2 years
Associations- middle aged females and DM
Management of adhesive capsulitis
May want an X ray to rule out pathology
Conservative- physiotherapy
Medical- NSAIDs, intra articular corticosteroids
Surgery- surgical release of the capsule
Webers classification of ankle fractures
Describe fractures of the lateral malleolus (distal fibula). The fracture is described in relation to the distal syndesmosis (fibrous join) between the tibia and fibula.
A- below syndesmosis
B- at level of syndesmosis
C- above syndesmosis which may be damaged
Management of an ankle fracture
Orthopaedic referral
Reduce
Surgical repair (older- conservative)
Ottawa rules for ankle x ray
Pain in malleolar zone and one of following;
- bony tenderness at medial malleolus
- bony tenderness at lateral malleolus
- inability to walk 4 weight bearing steps
What is a sprain
A stretching, partial, or complete tear of a ligament
Low ankle sprain
Most common- injury ATFL
Inversion injury
Usually able to weight bear unless severe of or high ankle sprain
RICE (rest, ice, compression, elevation)
Orthotics
Rarely surgery
High ankle sprain
External rotation of the foot
Weight bearing painful
Pain when fibula and tibia squeezed together
RICE (rest, ice, compression, elevation)
Orthotics
Rarely surgery (if diastisis eg. Tibia and fibula have separated)
Causes of a vascular necrosis of the hip
Long term steroids
Chemotherapy
Alcohol excess
Trauma
Features of AVN hip
Initially asymptomatic
Pain in affected joint
Investigations and management of AVN hip
X rays- may be normal (later- osteopenia and micro fractures, collapse of articular surface (crescent sign))
MRI- Gold standard
Refer to ortho- joint replacement
Bakers cyst
Can be primary or secondary to OA/ meniscal tears/ RA/ knee injuries or disease
Usually asymptomatic, if ruptured- DVT symptoms
Risk factors for biceps tendon rupture
Heavy overhead activities
Shoulder overuse/injury
Smoking
Corticosteroids (weaken tendons)
Features of biceps tendon rupture
Pop at distal or proximal tendon (with pain swelling and bruising)
Pop eye deformity if proximal/long tendon ruptures
Weakness on shoulder and elbow
Investigations and management of a biceps tendon rupture
Orthopaedic referral
Biceps squeeze (intact- forearm supination)
USS
Proximal- conservative
Distal- MRI, surgical
Buckle/torus fracture
Incomplete fracture of shaft of long bone with bulging of cortex (children)
Splinting and immobilisation
Carpal tunnel syndrome features
Compression of median nerve in carpal tunnel
Sensory- Pain/pins and needles in thumb, index, and middle fingers
Motor;
Weakness of thumb movements
Weakness of grip strength
Difficulty with fine movements involving the thumb
Wasting of the thenar muscles (muscle atrophy)
Symptoms ascend proximally
Patients shake hand to obtain relief typically at night
Causes of carpal tunnel
Idiopathic
Pregnancy
Oedema (heart failure)
Lunate fracture
Rheumatoid arthritis
Causes of bilateral carpal tunnel (look out for other features of the condition in exam)- rheumatoid arthritis, diabetes, acromegaly or hypothyroidism
Examination in carpal tunnel
Weakness of thumb abduction
Wasting of thenar eminence (not hypothenar)
Tinnels- tapping causes parasthesia
Phalens- flexion of wrist worsens symptoms
Investigations
Observations, hand and wrist exam
Bloods- DM, B12 deficiency, other routine bloods to exclude paraesthesia
Specialist- nerve conduction studies
Treatment
Conservative- wrist splints
Medical- corticosteroid injections,
Surgical- surgical decompression (cut flexor retinaculum)
