Biomechanical comparison between standard and inclined screw orientation in dynamic hip screw side-plate fixation: The lift-off phenomenon

Journal of Orthopaedic Translation, 2019
Background: Common failure modes of dynamic hip screw are cut-out and lift-off. To minimize the latter, distal screws can be inserted in different orientations. However, the effectiveness remains controversial.

Outcome of the Dynamic Helical Hip Screw System for Intertrochanteric Hip Fractures in the Elderly Patients

Geriatric Orthopaedic Surgery & Rehabilitation, 2012
Introduction: The dynamic helical hip system (DHHS; Synthes, Paoli, Pennsylvania) differs from the standard dynamic sliding hip screw (SHS) in that in preparing for its insertion, reaming of the femoral head is not performed, thereby preserving bone ...

Use of the Tip-Apex Distance in predicting Dynamic Hip Screw Cut Out in Intertrochanteric Fracture of the Femur in Asian Population [PDF]

Malaysian Orthopaedic Journal, 2011
The objective of this study was to assess the rate of screw cut out in elderly patients treated with the dynamic hip screw and the relationship to the Tip Apex Distance (TAD).

Comparison and analysis of reoperations in two different treatment protocols for trochanteric hip fractures – postoperative technical complications with dynamic hip screw, intramedullary nail and Medoff sliding plate

BMC Musculoskeletal Disorders, 2017
Background In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment.

Comparing the volume of vascular intersection of two femoral neck fracture fixation implants using an In silico technique

OTA International, 2023
Background:. Femoral neck fracture displacement with subsequent vascular disruption is one of the factors that contribute to trauma-induced avascular necrosis of the femoral head.

Intra-Pelvic Migration of Sliding Hip Screw During Osteosynthesis of Hip Fracture: A Rare Avoidable Intraoperative Complication. [PDF]

, 2015
Hip fractures, which are common among old patients, are classified into two groups: intracapsular and extracapsular fractures. Extracapsular fractures can be treated with extramedullary implants [e.g.

Development of a test system to analyze different hip fracture osteosyntheses under simulated walking [PDF]

, 2012
The mechanical complications of osteosyntheses after hip fractures are previously investigated by mostly static or dynamic uniaxial loading test systems.

Reliability of predictors for screw cutout in intertrochanteric hip fractures [PDF]

, 2012
Background: Following internal fixation of intertrochanteric hip fractures, tip apex distance, fracture classification, position of the screw in the femoral head, and fracture reduction are known predictors for screw cutout, but the reliability of these ...

Incredible position of broken sliding dynamic hip screw implant in the medial of thigh

Acta Orthopaedica et Traumatologica Turcica, 2018
We report a case with implant failure after nailing of an unstable pertrochanteric fracture with dynamic hip screw. The patient presented with a medial sided thigh pain at 5 years after the surgery.
