🏴‍☠️ The Bonesetter, the Workshop, and the Splint | Dr. Hugh Owen Thomas (1834-1891)
Every fracture repair can trace a direct line back to a workshop on Nelson Street, Liverpool, and a 5’3” Welsh surgeon in a black frock coat who never held a hospital appointment. Hugh Owen Thomas was descended from a 5-generation dynasty of Welsh bonesetters (meddygon esgyrn) that began with a shipwrecked boy washed ashore on Anglesey around 1745. DNA evidence later traced that boy’s origins to the Caucasus mountains.
Thomas qualified in Edinburgh (1857) and could have practiced anywhere. Instead, he built something new in the world — a workshop clinic at 11 Nelson Street w/ a full-time blacksmith and leather worker fabricating the splints he designed himself. He worked 7-dys a week for 30+ years. No hospital affiliation. No holidays. London ostracized him as a glorified bonesetter, and he simply kept working. His core principle was rest — enforced, uninterrupted, and prolonged. In an era of aggressive intervention, he insisted that bones and joints needed time, immobility, and traction to heal. “An overdose of rest is impossible,” he wrote. He proved it.
His nephew, Sir Robert Jones, came to Nelson Street as a 16-yo apprentice in 1873. As Inspector of Military Orthopaedics in WWI, Jones deployed the Thomas splint to the Western Front. Mortality from compound femoral fractures collapsed from roughly 80% (1916) to 8% by 1918. Thomas had been dead for 25-yrs. Sir Arthur Keith said his profession was his hobby. S. B. Mostofi later wrote: “No other pioneer contributed so much in establishing the fundamental principles of orthopedic surgery.”

Bilateral Knee Replacement: One Surgery or Two?
Roughly 1 in 3 patients facing has arthritis in both knees, raising a question: should we replace both knees at once, or stage the surgeries months apart? The honest answer is that it depends. A 2025 systematic review/meta-analysis published (Journal of Arthroplasty) examined >366,000 patients across 69 studies. Simultaneous bilateral (BTKA) reduced total operating time by ~25 minutes, shortened hospital stays by ~5 dys, and produced lower rates of deep infection, wound complications, and overall TKA-related complications. Patient-reported outcomes were also marginally better.
The same data showed real tradeoffs. Simultaneous BTKA carried higher mortality at 1 mo, 3 mos, and 1 yr, along with elevated rates of pulmonary embolism, deep vein thrombosis, and neurologic & gastrointestinal complications. By 2-yrs out, mortality differences resolved. What this means in practice: simultaneous BTKA is a powerful option for the right patient — typically healthier individuals w/o significant cardiopulmonary disease, often

Father of Modern Hip Replacement — Sir John Charnley (1911-1982)
Every hip replacement performed today descends from the work of one surgeon. Sir John Charnley was born in 1911 (Bury, England), the son of a pharmacist who practiced dentistry in the back room of his shop. He almost became a dentist himself. A schoolmaster convinced him to choose medicine instead. The Second World War made him. Stationed in Cairo, he ran a military orthopedic workshop, manufacturing surgical instruments by hand. He didn’t just use surgical tools. He made them. That mechanical fluency would prove more important than any operating room training.
In the 1950s, a patient with an artificial hip came to him with a strange complaint — his hip squeaked so loudly his wife would leave the room. Charnley realized the joint had no effective lubrication. He spent the next decade searching for a material with friction low enough to mimic the human body. His first attempt failed catastrophically. After 300 implants, the material was destroying surrounding bone. His technician, Harry Craven, kept testing alternatives despite Charnley telling him he was wasting his time. The material Craven found — ultra-high molecular weight polyethylene — became the foundation of modern total hip arthroplasty. When Charnley finally published (1972), ~90% of his patients were pain-free. Over 80% who had been confined to crutches were walking unaided. He built a sterile operating enclosure he called a “greenhouse.” He designed full-body exhaust gowns. He refused to sell his prosthesis to any surgeon who hadn’t trained at Wrightington.

🪝Inside Anterior Hip Replacement: Surgical Table Feature That Changes Everything
Born in a hotrod shop, this surgical attachment makes direct anterior approach possible - and it comes down to engineering. The specialized orthopedic (HANA) table and its femoral hook attachment assists what surgeons can safely accomplish through this muscle-sparing approach. The gives excellent direct access to your acetabulum (hip socket), but reaching your femur can be a challenge. Unlike posterior or lateral approaches, we can’t simply flip the leg to deliver the proximal femur into the wound. The femoral hook makes a difference. Developed by Dr. Joel Matta after a particularly difficult case involving a former heavyweight boxer with dense gluteal/thigh musculature, the hook-lift concept (originally fabricated by a Southern California car shop) is a key feature of the Hana table.
In the OR, the hook is positioned just distal to the vastus ridge, wrapping around the posterior femur superficial to the vastus lateralis origin. Once your leg is extended + adducted + externally rotated so the calcar faces anterior, the hook engages a powered lift bracket that supports (not force) the proximal femur into an anterior position. Sequential capsular releases then elevate the femur to the ideal position for broaching & stem insertion. Better femoral exposure translates to more accurate component placement, fewer intraop complications, and preserved soft tissue. Good tools never replace surgical judgment or technique - but the hook may deserve a little more credit.

“The Michelangelo of Orthopaedics.” | Dr. Gavriil Ilizarov
That title wasn’t given by a colleague or a committee. It came from Carlo Mauri — an Italian mountaineer who traveled behind the Iron Curtain in 1980 to find the one surgeon who could fix a fracture others had abandoned. Dr. Ilizarov was born into poverty (1921) and grew up hungry, grazing cattle for villagers, and didn’t enter school until he was 11. A local doctor’s assistant saved his life as a child and set the course of everything that followed. By 22, he was practicing medicine alone in Dolgovka — a remote Siberian village with no orthopedic department, no specialists, and no modern equipment.
What he had was an endless line of soldiers returning from the Eastern Front with shattered limbs. Ilizarov decided the problem wasn’t just the injuries, it was the treatment. He drew inspiration from a horse harness, enlisted a local metalworker, tested prototypes on broken broomsticks, and built the first external ring fixator from bicycle parts. The Moscow establishment called him a quack. He spent decades proving them wrong. In 1967, he treated Olympic high jump champion Valeriy Brumel after other surgeons had failed across several procedures. When Ilizarov finally spoke outside the Iron Curtain at Bellagio (1981), the room gave him a ten-minute standing ovation. From a rural hospital with nothing, he built the world’s largest orthopedic center: 800 beds, 24 operating rooms, 9,000 patients treated annually. His method — distraction osteogenesis — proved bone could regenerate, lengthen, and reshape through controlled tension and is still used today. As late as 1991, the establishment still refused him full recognition. His patients never did.
