The entry point for a Dynamic Condylar Screw (DCS) in the proximal femur is a specific anatomical location crucial for proper surgical fixation.
DCS Entry Point Details
Based on surgical guidelines, the precise entry point for the DCS device in the proximal femur is defined by several key anatomical landmarks:
- Vertical Location: Situated 0.5 to 1 cm just above the junction where the flared part of the greater trochanter meets the main femoral shaft.
- Horizontal Location: Found at the meeting point of the anterior and middle thirds of the greater trochanter.
- Alternative Description: This horizontal location can also be described as being at the junction between the anterior 1/3 rd and posterior 2/3rds of the greater trochanter.
Summary of Location
Here's a breakdown of the location based on the reference:
| Aspect | Description |
|---|---|
| Vertical | 0.5 to 1 cm above the junction of the greater trochanter flare and femoral shaft |
| Horizontal | At the meeting point of the anterior and middle thirds of the greater trochanter |
| Alternative H | At the junction between the anterior 1/3 rd and posterior 2/3rds of the greater trochanter |
This carefully chosen entry point helps ensure optimal placement of the DCS barrel and screw for stable fixation of certain proximal femur fractures, particularly supracondylar and distal femoral fractures extending proximally.
