When dealing with proximal femur fractures, especially the nasty unstable ones in older folks, surgeons often grab the Intertan nail from Smith & Nephew. It’s not your everyday rod—its smart dual-screw setup, with a sliding hip screw working alongside an anti-rotation screw, gives unbeatable control over spinning and lets the break compress naturally as the patient moves. This makes it the top pick when simpler nails just wouldn’t cut it.
Unstable Intertrochanteric Fractures (AO/OTA 31-A2 and A3)
These are Intertan’s bread and butter. Picture AO 31-A2 or A3 patterns where the posteromedial bone wall is smashed or gone. The nail’s sliding feature lets fragments hug together under real body weight, while the second screw stops the femoral head from twisting loose. In the OR, this slashes varus collapse—where the head tips inward—far better than single-blade nails like PFNA. Patients with reverse obliquity or chewed-up lateral walls heal strong over 95% of the time, dodging cut-out headaches.
Osteoporotic Fractures in Elderly Patients
Brittle bones in folks over 75 turn fixes into a gamble, but Intertan grips like a champ. Its screw-in-screw magic spreads into more spongy cancellous bone for 30-40% stronger hold than solo screws. No more head wobble in soft trabeculae—patients hit full weight by week 6, scoring 10-15 points higher on Harris Hip tests a year out. Plus, less thigh ache from cortex rubbing means quicker steps without the drama.
Why It Beats the Rest Here?
The dual setup locks rotation tight, and controlled slide keeps alignment spot-on. Compared to Gamma Nails, it compresses better; versus PFNA2, fewer failures in A2.3 patterns.
Subtrochanteric Fractures with Shaft Extension
When breaks stretch into the subtrochanteric zone (AO 32-A), Intertan’s long versions—up to 400 mm—bridge that shaky metaphyseal-diaphyseal spot perfectly. Hitting the natural 130° neck-shaft angle, it slides 5-10 mm to seal gaps, pushing primary healing without callus overload. Beats TFNA hands-down for rotation control, skipping the Z-effect where one screw bails and overloads the other.
Pathological Fractures and Nonunions
Cancer-weakened bones or funky nonunions? Intertan shines with light reaming to spare stock, load-sharing for instant mobility in short-expectancy cases. Dynamization fixes varus on the fly, dropping revisions under 5%—way ahead of plates that drag soft tissues.
Quick Specs for These Cases
Standard 10-13 mm diameters, Asian slim fits for narrow canals. Ops run 45-60 min for dual screws, but revisions stay under 3%. Avoid in infections or sub-9 mm canals.
Practical Tips from the Trenches
Insertion’s straightforward: ream minimally, guide the lag screw first, add the anti-rotator, lock distally. Fluoro checks neck-shaft angle religiously. Post-op, early walkers thrive—no slings needed.
In high-wire acts like elderly osteoporosis, reverse obliquity issues, or shaft creeps, Intertan isn’t just solid—it’s the smartest trauma implant. Turns tough breaks into wins, getting patients upright and steady without endless callbacks.
