Failure of PFNA: helical blade perforation and tip-apex distance.
Since the clinical introduction of proximal femoral nail antirotation (PFNA) by AO group in 2004 and PFNA-II (Asian version) in 2008, this type of cephalomedullary nail with single head-neck helical blade were commonly used in unstable pertrochanteric and intertrochanteric fractures in geriatric patients. Recently, severe complications of helical blade perforation through the femoral head, into...
متن کاملThe prognostic value of tip-to-apex distance (TAD index) in intertrochanteric fractures fixed by dynamic hip screw
Intertrochanteric fractures (ITFs) are the most common type of fractures requiring surgical intervention. They also have the highest surgical mortality among orthopedic operations. Among the many different techniques used for fixation of this type of fracture, use of the Dynamic Hip Screw (DHS) has gained wide acceptance. This current study was designed to assess positive predictive value of ti...
متن کاملAwareness of tip-apex distance reduces failure of fixation of trochanteric fractures of the hip.
We compared the results of the surgical treatment of trochanteric hip fractures before and after surgeons had been introduced to the tip-apex distance (TAD) as a method of evaluating screw position. There were 198 fractures evaluated retrospectively and 118 after instruction. The TAD is the sum of the distance from the tip of the screw to the apex of the femoral head on anteroposterior and late...
متن کاملThe tip-apex distance in the X-Bolt dynamic plating system
OBJECTIVES The Sliding Hip Screw (SHS) is commonly used to treat trochanteric hip fractures. Fixation failure is a devastating complication requiring complex revision surgery. One mode of fixation failure is lag screw cut-out which is greatest in unstable fracture patterns and when the tip-apex distance of the lag screw is > 25 mm. The X-Bolt Dynamic Hip Plating System (X-Bolt Orthopaedics, Dub...
متن کاملTip Apex Distance: a useful method to assess extra-capsular neck of femur fixation?
The Tip Apex Distance (TAD) is a simple measurement that predicts screw cut-out in the femoral head from trochanteric fractures treated with a fixed angle sliding hip screw device [1]. It uses a numerical value to show placement of the screw in the head: higher values indicating higher likelihood of fixation failure by extrusion of the screw. Currently the cost of hip fracture care in the UK is...
