Summary
The dynamic hip screw (DHS) blade effectively treats intertrochanteric hip fractures, showing good healing and low complication rates over one year. Functional mobility decreased, but the DHS blade proved reliable for AO/OTA 31-A1 and 31-A2 fractures.
Area of Science:
- Orthopedic surgery
- Traumatology
- Geriatric medicine
Background:
- Intertrochanteric hip fractures are common, particularly in the elderly.
- Optimal fixation methods are crucial for patient recovery and mobility.
Purpose of the Study:
- To evaluate the one-year outcomes of using a dynamic hip screw (DHS) blade for AO/OTA 31-A1 and 31-A2 intertrochanteric hip fractures.
Main Methods:
- A cohort of 100 patients (35 male, 65 female; aged 47-100) with low-energy hip fractures underwent DHS blade fixation.
- Radiographic analysis assessed tip-apex distance and femoral shortening; complications and functional outcomes (Parker mobility score) were monitored.
Main Results:
- All fractures healed without varus deformity at one year.
- Mean tip-apex distance was 14.1 mm, and mean femoral shortening was 4.9 mm.
- Parker mobility score decreased significantly from 5.9 pre-injury to 3.8 at one year; one fixation loss occurred.
Conclusions:
- The DHS blade system demonstrates efficacy in treating AO/OTA 31-A1 and 31-A2 intertrochanteric hip fractures.
- The system is associated with a low rate of complications, supporting its use in this patient population.
