Objectives: This study aims to compare dynamic hip screw (DHS) with trochanteric stabilizing plate (TSP) versus short proximal femoral nail (PFN) in unstable trochanteric fractures in terms of the functional and radiological outcomes.
Patients And Methods: Between June 2019 and March 2020, a total of 68 patients (32 males, 36 females; mean age: 69.7±8.2 years; range, 60 to 88 years) with unstable trochanteric fractures were included in this randomized-controlled trial. Eligible patients were randomized to undergo DHS with TSP (n=34) or short PFN (n=34) and followed for 12 months. The outcome measures including Harris Hip Score (HHS), operating room time, the amount of blood loss and need for intraoperative transfusion, return to activity, time to union, postoperative complications, failure rate, and mortality rate were analyzed.
Results: The mean operative time in the DHS+TSP group was 105±10 min, while in the PFN group it was 94±8 min (p=0.001). The mean time until union in the DHS+TSP group was 10.1±1.9 weeks, while in the PFN group, it was 8.8±1.8 weeks (p=0.008). The mean time to return to the pre-fracture activity level in the DHS+TSP group was 12.6±2.6 weeks, while in the PFN group, it was 10.8±2.1 weeks (p=0.005). The mean HHS for the DHS+TPS group was 77.9±8.4, while for the PFN group, it was 80.4±8.7 (p=0.26). There was no significant difference in the walking capability between the two groups. One-year mortality rate was 29.4% in the PFN group and 17.6% in the DHS+TSP group (p=0.284), indicating no significant difference. Mechanical failure was recorded in three cases (8.8%) in the DHS+TSP group compared to two cases (5.8%) in the PFN group with no statistically significant difference. These five cases needed later revisions with total hip replacement.
Conclusion: The use of PFN in unstable trochanteric fractures was associated with a shorter time until union and a faster return to the pre-fracture level of activity than the DHS+TSP group. Postoperative hip function, walking independence, as well as complication and one-year mortality rates were comparable.

Lateral femoral wall thickness in trochanteric hip fractures: a systematic review.

Trauma and Orthopaedics, The Shrewsbury and Telford NHS Trust, UK.
Background: Thin lateral femoral wall has been investigated as a sign of instability in trochanteric hip fractures, necessitating lateral wall reconstruction or the use of a cephalomedullary nail (CMN). Various cut-off values have been proposed to guide implant choice. This review aims to determine the clinical significance of the lateral femoral wall thickness (LWT) in trochanteric hip fractures and identify an optimal cut-off value for increased risk of lateral wall (LW) fracture when using Dynamic Hip Screw (DHS).

Purpose: Intertrochanteric fractures can be classified as stable (AO-OTA 31-A1) or unstable (AO-OTA 31-A2/3). For A3 fractures there is no recommended treatment, often fixed with either an intramedullary nail (IMN) or a dynamic hip screw and trochanteric stabilisation plate (DHS/TSP). This study retrospectively reviews peri-operative outcomes of patients treated with either fixator.

Dynamic Hip Screw with Trochanter-Stabilizing Plate Compared with Proximal Femoral Nail Antirotation as a Treatment for Unstable AO/OTA 31-A2 and 31-A3 Intertrochanteric Fractures.

Background: The dynamic hip screw (DHS) with the addition of an angular stable trochanter-stabilizing plate (TSP) has been considered the ideal treatment for the unstable intertrochanteric fracture type. However, there have been few comparisons between DHS+TSP augmentation with intramedullary (IM) nailing. The aim of this retrospectively registered study was to compare the clinical outcomes of patients with the unstable type of intertrochanteric fractures treated with DHS+TSP or IM nailing (proximal femoral nail antirotation (PFNA)).

Introduction: Unstable trochanteric fractures are challenging with a high rate of implant failure and re-operation. Cephalomedullary nails proved to be a rational management choice for these injuries, yet other management options have not been well assessed. The aim of this study was to compare the use of DHS with trochanteric stabilizing plate (TSP) and proximal femoral locked plate (PFLP) in unstable pertrochanteric fractures.
