Summary

This study presents a new technique for hip fracture fixation, improving guide pin accuracy in obese patients. The method uses preoperative skin markings and a plumb line for precise anteroposterior placement, aiding short incisions.

Area of Science:

  • Orthopedic surgery
  • Surgical techniques

Background:

  • Percutaneous hip fixation requires precise guide pin placement.
  • Increased skin-to-greater trochanter distance, common in obese patients, complicates accurate pin insertion.
  • Femoral neck positioning not parallel to the floor further challenges standard techniques.

Purpose of the Study:

  • To describe a novel technique for percutaneous hip fixation.
  • To simplify guide pin insertion, especially in obese individuals.
  • To facilitate shorter surgical incisions.

Main Methods:

  • Preoperative skin marking for guide pin placement.
  • Utilizing a plumb line to determine the anteroposterior mark, deviating from traditional arc methods.
  • Standard lateral mark for reference.

Main Results:

  • The described technique aids in accurate guide pin placement.
  • Facilitates shorter incisions, beneficial for obese patients.
  • Overcomes challenges posed by increased soft tissue depth and non-parallel femoral neck positioning.

Conclusions:

  • This new technique offers a reliable method for guide pin insertion in percutaneous hip fixation.
  • It is particularly advantageous for obese patients, enabling shorter incisions and improved accuracy.
  • The use of a plumb line simplifies the anteroposterior landmark identification.
