Learn the HIPpie culture that's picking up in 2026

Liner change… - For OA! #NeoArmory:

‘THR is so 2025’ is what I would say if I invented a 3D printed Biodegradable liner which can dissolve to form ‘normal’ cartilage.

CytexOrtho, a US based company have designed ReNew^TMHip implant which has 3D printed porous woven textile to mimic cartilage and a base to facilitate anchorage. Overtime, cells ‘move into the gaps’, implants dissolves and ‘creates 100% healthy tissue’.

They do both femoral head and acetabular components

The ReNew hip clinical trial has commenced and recruiting subjects.

But notably, this would require a safe surgical dislocation to implant. As the implant does not have structural stability, it cannot be used if there is contour mismatch.

Let’s wait for the results!

Adolf Lorenz – A surgery which costed around $75,000 and no blood involved! #FromTheHistory:

All of us would have seen patients who doesn’t want surgical intervention and ask “is there any other way?” Interestingly, there was an Austrian “surgeon” who built his entire career around the same idea.

Adolf Lorenz (1854-1946) was famously known as “Bloodless surgeon of Vienna”. Mind you it was not some gimmick created for marketing, he indeed was a bloodless surgeon and the story behind this is quite fascinating.

Lorenz decided to become a surgeon at 26 after just completing his graduation but fate had other plans. Within 4 years, he developed severe allergy to Carbolic acid which was used extensively in operation theatres to achieve asepsis. Being bitten by the love for surgery, he just could not give up and instead he chose to become a dry surgeon, meaning, not cutting the skin but perform manipulations. He invented manipulation techniques for several conditions like Club foot, scoliosis etc but he was famous for his treatment of congenital hip dislocation.

Lorenz’s most famous case which made him a celebrity is about Lolita Armour, granddaughter of one of the richest man in USA at the time, Philipp D Armour. She was born preterm at 34 weeks weighing barely 3 pounds with congenital dislocation of hip. She even underwent a surgery in the USA which unfortunately was not successful.

At the time, Lorenz’s bloodless surgeries were the talk of the town, or rather talk of the world. Lolita was too fragile to travel to Vienna and so the family requested Lorenz and the team to USA. This created a Media Frenzy and public excitement. It is said that Lorenz and the team have charged around a $100,000 including their travel expenses (This was more than a century ago, now get that!).

There was even a controversy about Lorenz’s license to treat patients in the USA. This, however was swiftly handled when the Illinois State Examination Commission granted him immediate permission to practice, reportedly under pressure from Chicago physicians.

Finally, Lolita, after a trip to Vienna for rehabilitation was said to gain almost normal gait and the parents as well as herself were happy about it.

However, there has always been a skepticism in the orthopaedic fraternity about the complications and success rates with the bloodless surgeries performed by Lorenz and with time, the concerns grew into reality with loads of patients with high complication rates especially Avascular necrosis and redislocation. In hindsight, Lorenz’s story teaches us that however bold your ideas are, what matters is the long-term success not the early results.

The Poller pin technique for subtrochanteric fractures - #SurgicalPearl:

Yoon et al. explain how poller (blocking) screws can be smartly used during intramedullary nailing to guide the nail, improve entry point accuracy, and correct malalignment—especially varus and flexion deformities, which are common in subtrochanteric fractures .

Again the poller pins as traffic dividers inside the bone.

1. Correcting varus deformity (AP plane)

Varus usually happens when the nail starts too lateral or the proximal fragment drifts medially.

Place a poller pin lateral to the nail path near the greater trochanter. This pushes the nail medially and prevents varus.
Metaphyseal-level problem (short proximal segment):

Place a poller pin medially at the metaphysis. This blocks medial drift and restores neck–shaft alignment.

2. Correcting flexion / extension deformity (lateral plane)

Subtrochanteric fractures love to go into flexion because of iliopsoas pull.

If the proximal fragment is flexed:
- Place a posterior poller pin → forces the nail anteriorly → corrects flexion.
For extension deformity (less common):
- Place an anterior poller pin to redirect the nail posteriorly.

3. Technical pearls

Insert poller pins before reaming or nail passage
Use bicortical placement for strength
Convert Steinmann pin to a 4.5 mm cortical screw if needed
Avoid blocking the path of proximal recon screws
Be careful not to blow out the proximal fragment

Please close the door after you leave - in Hip arthroscopy! #MostCited:

During hip arthroscopy, closing the capsule is seen as a way to restore the joint’s natural balance and improve outcomes, while leaving it open can help loosen stiff hips but carries a small risk of instability. To weigh these options more clearly, expected‑value decision analysis (EVDA) offers a cool framework that blends probabilities with patient‑valued benefits, helping identify which path brings the most positive energy overall.

Phillips et al. performed an EVDA for this case and their results showed that complete capsule closure carried a higher expected value and greater probability of well outcomes compared with incomplete closure.

Finally, complete closure emerged as the superior management choice, offering better outcomes and fewer complications such as revision surgery or conversion to THA.
