Extracapsular hip fractures: fixation with a twin hook or a lag screw?

Area of Science:

• Orthopedics
• Trauma Surgery
• Biomedical Engineering

Background:

• Trochanteric hip fractures are common, particularly in elderly patients.
• Current fixation methods include lag screws and dynamic plates.
• The twin hook presents a novel alternative for fracture fixation.

Purpose of the Study:

• To compare the efficacy and safety of the twin hook versus the lag screw for trochanteric hip fracture fixation.
• To evaluate postoperative migration and fixation failure rates between the two fixation methods.

Main Methods:

• A prospective study involving 102 patients with trochanteric hip fractures.
• Patients were treated by 19 surgeons using either a twin hook or a lag screw with a sliding hip screw plate.
• Data collected included intraoperative errors, postoperative migration, and fixation failures.

Main Results:

• Seven intraoperative errors were noted with the twin hook.
• No significant difference in postoperative migration was observed between the twin hook and lag screw groups.
• Fixation failure rates were comparable between the two treatment groups.

Conclusions:

• The twin hook provides adequate and comparable fixation to the lag screw for trochanteric hip fractures.
• Despite some intraoperative challenges, the twin hook demonstrates similar clinical outcomes to the lag screw.
• The twin hook is a viable alternative for trochanteric hip fracture fixation.
