Uncemented bipolar hemiarthroplasty with trochanteric clip and cable stabilisation as primary treatment for unstable intertrochanteric fractures in elderly patients with major comorbidities
This study demonstrates that uncemented bipolar hemiarthroplasty with trochanteric clip and cable stabilisation is an effective primary treatment for unstable intertrochanteric fractures in elderly patients with significant comorbidities, enabling early mobilization and achieving an 84.78% success rate at six months.

Imagine an elderly person's hip as an old, fragile house built on shaky ground (osteoporotic bone). When a storm hits, the roof (the femur) cracks in a messy, unstable way. This is what doctors call an unstable intertrochanteric fracture.
For decades, the standard repair method was like trying to patch up that cracked roof with nails and screws (internal fixation). But because the wood is so rotten, the screws often pull out, the roof collapses again, and the patient is stuck in bed for months. For an elderly person with other health issues (like diabetes or heart trouble), being stuck in bed is dangerous—it's like leaving a house unattended; the walls start to crumble, and new problems (like blood clots or bedsores) appear quickly.
This research paper suggests a different approach: instead of patching the roof, just replace the whole damaged section with a new, sturdy door.
Here is a simple breakdown of what the study found:
The New Strategy: Swapping the Broken Part
The researchers looked at 46 elderly patients (average age 68) who had these messy, unstable hip fractures. Many of them were already quite sick, dealing with uncontrolled diabetes, heart disease, or kidney issues.
Instead of trying to glue the broken bone back together, the surgeons performed a bipolar hemiarthroplasty.
- The Analogy: Think of the hip joint as a ball-and-socket. The "ball" at the top of the thigh bone broke. Instead of trying to tape the ball back together, they removed the broken ball and replaced it with a new, artificial metal ball.
- The "Uncemented" Twist: Usually, you might glue a new part in with cement. But these surgeons used a special "uncemented" design. It's like a puzzle piece that fits tightly into the bone on its own, relying on friction and the bone's natural ability to grow into the metal, rather than a sticky glue.
- The "Trochanteric Clip": The top part of the hip bone (the trochanter) often shatters in these fractures. The surgeons used a special metal clip and cable (like a heavy-duty zip-tie) to hold that shattered piece together so it wouldn't fly off.
The Results: Getting Back on Feet Fast
The study tracked these patients for six months. Here is what happened:
- Speed: Because they didn't have to wait for the bone to heal (since they replaced the broken part), patients could stand up and walk with full weight almost immediately after surgery. It's like swapping a broken wheel on a car and driving away right away, rather than waiting for the tire to be patched.
- Recovery:
- At 6 weeks, their hip function was "fair" (a score of about 68 out of 100).
- At 3 months, it jumped to "good" (81/100).
- At 6 months, it was "good" to "excellent" (85/100).
- Success Rate: About 85% of the patients had a "good" or "excellent" outcome. They were able to move around well again.
- Who did it help? It worked well for both men and women, and surprisingly, it didn't matter much if the patient had diabetes, heart disease, or was slightly older. The method seemed robust enough to handle the "sick" patients who usually struggle with other surgeries.
The Bottom Line
The paper concludes that for elderly patients with weak bones and multiple health problems, trying to fix the broken hip with screws is risky and often fails.
Instead, replacing the broken top part of the hip with a new metal ball (hemiarthroplasty) is a safer, faster way to get them walking again. It avoids the long, dangerous wait for bone healing and gives them a much better chance of recovering their independence without needing a second, more difficult surgery later.
In short: When the bone is too rotten to hold a screw, swap the part entirely. It's the "replace, don't repair" strategy that got these patients back on their feet quickly.
