supracondylar

Subcapital Femoral Neck Metastasis

Fractures

Principle

- do very poorly with fixation

- hemiarthroplasty or THR

- stem should be 2.5 cortical diameters beyond any area of weakness

- THR if acetabulum involved

Problem

1.  Undulating growth plate / higher rate of growth plate injury

- growth arrest / LLD

- angular deformity

- need to be warned

- require close and careful follow up especially in first 2 years

2.  Can be unstable / malunion and shortening very problematic in this area
