Intertrochanteric Fractures


- Discussion:
    - frx occur as a result of a fall - from direct and indirect forces;
    - occurs along lines between greater and less trochanters;
    - theoretically extracapsular, however, it is not always possible to distinguish betwee intertroch and basilar femoral neck frx;
    - extracapsular intertroch frx occur thru cancellous bone, which has an excellent blood supply - hence, heals well;
          - that portion of the neck that is intracapsular has essentially no cambium layer in its fibrous covering to
                     participate in peripheral callus formation;
          - therefore, healing in femoral neck area is dependent on endosteal union alone;
    - forces acting on the hip joint
    - classification
          - basilar neck frx
          - stable intertrochanteric frx
          - unstable intertrochanteric frx
                   - lesser trochanteric frx
                   - reversed obliquity
                   - type-IV
                   - 4 part frx


- Radiographic Findings


- Non Operative Rx:
    - even w/o treatment, frx usually stabilizes w/ in 8 wks & allows wt bearing in 12 weeks;
    - however, marked varus of head & neck w/ assoc external rotation deformity usually results in a short leg gait & limp;


- Operative Treatment:
    - surgical work up
    - sliding screw insertion technique
    - intramedullary nail fixation

    - hip arthroplasty

- introduced in 1970;
- complications include: nails backing out of IM canal, perforation of nails thru femoral head, distal migration, and external rotational deformity at fracture site;
