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 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...
متن کاملWhat Is the Relevance of the Tip-Apex Distance as a Predictor of Lag Screw Cut-Out?
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. TAD is widely used in operating theaters as a surgical guideline in relation to the fixation of trochanteric fractures, and in clinical studies as a predictor of lag screw cut-out....
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 کاملHumeral Tip-apex-distance as a Prognostic Marker for Proximal Humeral Fractures in 203 Patients
BACKGROUND Humeral head fractures and their postoperative outcome remain a challenging problem in surgical daily routine. Predictive factors for loss of fixation are rare. OBJECTIVE Determination of predictive factors for the failure of osteosynthesis with the loss of fixation or migration of screws in humeral head fractures. METHOD From 1995 to 2011, 408 patients with proximal humeral frac...
