Rheumatoid Arthritis Rheumatoid arthritis is a chronic systemic inflammatory disease characterized by severe symmetrical peripheral joint pain and deformation due to erosive arthritis. It is progressive and drastically reduces quality of life, hence early referral and treatment is important. It…
Subtrochanteric Fracture Subtrochanteric fractures are proximal femur fractures that occur between the lesser trochanter and a point 5cm distal to the lesser trochanter. This region of the femur experiences high compression and tensile forces, has less blood supply, has a…
Intertrochanteric Fracture Intertrochanteric fractures are extracapsular fractures of the proximal femur that occur between the greater and lesser trochanter. There is an area of low bone mineral density known as the ward triangle bordered by the primary compressive trabeculae, principal…
Femoral Head Fracture Femoral head fractures are rare injuries that are usually associated with hip dislocation (10%). In posterior dislocation the femoral head hits the posterior rim of the acetabulum and fractures. On the other hand, anterior dislocation causes impaction…
Clavicle Fracture The clavicle is a long, curved bone that forms part of the shoulder girdle. It has a sternal end (rounded) and an acromial end (flat). Fractures commonly occur in the middle third of the clavicle, which is the…
Proximal Humerus Fracture The most common fracture pattern of the proximal humerus is a transverse fracture. Most fractures are non-displaced and are treated non-operatively. It has a bimodal distribution. 70% of cases occur in women. It is the 3rd most…
Anatomy of the Knee Joint The knee is a modified hinge joint that articulates the femur to the patella and tibia. It is ‘modified’ because it allows for some degree of internal and external rotation, in addition to flexion and…
Parkinson Disease Parkinson’s disease is a progressive neurodegenerative disorder that results in abnormalities in movement, autonomic function and cognition. It is caused by degeneration of dopaminergic neurons in the substantia nigra pars compacta, a nucleus that is involved in the…

Transient Ischemic Attack A transient ischaemic attack (TIA) is defined as neurological deficits that completely resolve within 24 hours. 80% of TIAs are due to thromboemboli and they occur almost exclusively in patients with symptomatic large vessel disease e.g. carotid…
