Orthopaedics Flashcards
What nerve injury can occur with a neck of fibula injury + features
Common peroneal nerve injury
Leads to foot drop- weakness dorsiflexion, eversion and great toe extension. Sensory loss dorsum foot and lower lat part of leg
Management of intracapsular hip fractures
Undisplaced:
- internal fixation
Displaced:
- total or hemi hip replacement
total hip replacement is favoured to hemiarthroplasty if patients:
-> were able to walk independently out of doors with no more than the use of a stick and
- > are not cognitively impaired and
- >are medically fit for anaesthesia and the procedure.
Management of extracapsular hip fractures
stable intertrochanteric fractures: dynamic hip screw
if reverse oblique, transverse or subtrochanteric fractures: intramedullary device
adverse effects of bisphosphonates
- oesophagitis/ulcers
- osteonecrosis of the jaw- increased risk if poor dentition or on IV bisphos for cancer
- increased risk atypical proximal femoral shaft #s with alendronate use
How long should pts be on bisphosphonates?
Varies according to risk. Some authorities recommend stopping bisphosphonates at 5 years if the following apply:
- patient is < 75-years-old
- femoral neck T-score of > -2.5
- low risk according to FRAX/NOGG
When to start bisphosphonates
Pts aged >75 with fragility fracture should be started without scan
Pts aged <75y with fragility # should be referred for DEXA scan with reuslts used for a FRAX assessement to determine ongoing # risk
Features of polymyalgia rheumatica
- > 60y
- rapid onset (<1month)
- aching morning stiffness in proximal limb muscles (hips//shoulders) \
- mild polyarthralgia, lethargy, depression, low-grade fever, anorexia, night sweats
- raised inflamm markers ie ESR

Adhesive capsulitis
Adverse effects of hydroxychloroquinine?
Bulls eye retinopathy - all pts need ophthalmology assessment before starting and annual check up
What are the clinical features of pagets disease?
- the stereotypical presentation is an older male with bone pain and an isolated raised ALP
- bone pain (e.g. pelvis, lumbar spine, femur)
- classical, untreated features: bowing of tibia, bossing of skull
