New tip-apex distance and calcar-referenced tip-apex distance cut-offs may be the best predictors for cut-out risk after intramedullary fixation of proximal femur fractures [PDF]

Scientific Reports, 2022
Cut-out is one of the most common mechanical failures in the internal fixation of trochanteric hip fractures. The tip-apex distance (TAD), and the calcar-referenced tip apex distance (CalTAD) are the radiographic parameters that most predict the risk of ...

Mean Tip Apex Distance in Patients undergoing Dynamic Hip Screw Fixation for Pertrochanteric Fractures without using Traction Table: A Descriptive Cross-sectional Study [PDF]

Journal of Nepal Medical Association, 2022
Introduction: Dynamic Hip Screw fixation has shown to be equally effective compared to cephalomedullary nailing. The effectiveness of dynamic hip screw fixation for pertrochanteric fractures without using traction table is not well investigated.

Predictive value of tip apex distance and calcar-referenced tip apex distance for cut-out risk in intertrochanteric femur fractures treated with double lag screw proximal femoral nails [PDF]

Acta Orthopaedica et Traumatologica Turcica
Objective: Cut-out is a major mechanical complication following proximal femoral nailing for intertrochanteric femur fractures. Tip apex distance (TAD) and calcar-referenced TAD (CalTAD) are key radiographic parameters used to predict this complication.

Proposal of a modified tip apex distance for prediction of lag screw cut-out in trochanteric hip fractures [PDF]

SICOT-J, 2023
Introduction: Lag screw cut-out is a serious complication of dynamic hip screw fixation of trochanteric hip fractures. The lag screw position has been acknowledged as one of the important factors affecting the lag screw cut-out. We propose a modification

Impact of tip–apex distance and femoral head lag screw position on treatment outcomes of unstable intertrochanteric fractures using cephalomedullary nails [PDF]

Journal of International Medical Research, 2018
Background Cephalomedullary nails are frequently used in unstable intertrochanteric fractures. The implant position is an important factor for surgical success.

Key factors for increased tip-apex distance when treating intertrochanteric fractures with InterTAN nails [PDF]

Frontiers in Bioengineering and Biotechnology
BackgroundThe tip-apex distance is a key factor in predicting implant cut-out after intramedullary fixation for intertrochanteric fractures. This study aimed to evaluate the factors associated with an increased tip-apex distance when treating ...

Is calcar referenced tip-apex distance a better predicting factor for cutting out in biaxial cephalomedullary nails than tip-apex distance?

Journal of Orthopaedic Surgery, 2017
Purpose: To test the significance of calcar referenced tip-apex distance (CalTAD) and the length of anti-rotation screw (AR screw) as predictors for failure after biaxial cephalomedullary (CM) nailing of intertrochanteric fractures.

Predictive value of tip-apex distance and calcar-referenced tip-apex distance for cut-out in 398 femoral intertrochanteric fractures treated in a private practice with dynamic intramedullary nailing [PDF]

Frontiers in Surgery
IntroductionCut-out, a biomechanical complication, is one of the most common causes of internal fixation failure of trochanteric hip fractures. The tip-apex distance (TAD) and the calcar-referenced tip-apex distance (CalTAD) have been suggested as the ...

Is the tip-apex distance a reliable predictor of implant failure in surgical fixation of femoral neck fractures with the synthes femoral neck system device? [PDF]

BMC Musculoskeletal Disorders
Background The Tip-Apex Distance (TAD) is known to affect outcomes of traditional implants such as sliding hip screws (SHS). However, it is unclear if the TAD has the same effect on the Femoral Neck System (FNS).

What is the relevance of the tip-apex distance as a predictor of lag screw cut-out? [PDF]

PLoS ONE, 2013
Using a simple mathematical formulation, the relationship between the position of the lag screw tip (relevant to both intramedullary and extramedullary devices) and the concept of tip-apex distance (TAD) was derived.
