1. GLOSSARY
| Term | Definition |
|---|---|
| LSJL | A purported method for increasing height involving the application of compressive force to the epiphyses of long bones via clamps or other devices |
| Longitudinal Bone Growth | The process by which bones increase in length, occurring exclusively at the epiphyseal growth plates via endochondral ossification until their closure at the end of puberty |
| Epiphyseal Growth Plate | The cartilaginous region located between the epiphysis and diaphysis of immature long bones. It's the primary site of longitudinal bone growth |
| Endochondral Ossification | The process by which cartilage is systematically replaced by bone tissue, the fundamental mechanism of how growth plates generate new bone to lengthen the skeleton |
| Hueter-Volkmann Law | A fundamental law of skeletal mechanobiology stating that compressive mechanical forces inhibit longitudinal bone growth, while tensile (distractive) forces accelerate it |
| Wolff's Law | A principle describing how bone tissue adapts to mechanical loading by remodeling its microarchitecture. It governs changes in bone density and thickness and not bone length. |
| Cortical Bone | The dense and hard outer layer of bone responsible for its strength and structure. LSJL may influence this but not in a way that increases length |
| Trabecular Bone | The porous and sponge like inner bone network. Compression may cause microfractures here which leads to density changes |
| Mechanotransduction | The process by which bone cells (osteocytes, osteoblasts, chondrocytes) convert mechanical stimuli into a set biochemical signals influencing either bone formation or resorption |
| Mesenchymal Stem Cells (MSCs) | Multipotent stromal cells that can differentiate into a variety of cell types including osteoblasts (bone forming cells) and chondrocytes (cartilage forming cells) |
| Chondrogenesis | The process by which cartilage is formed |
| Endochondral Bone Formation | One of the two essential processes in fetal development of the skeletal system and the essential process for longitudinal bone growth. |
2. CENTRAL THESIS
The proposition that LSJL can increase height in adults is false. It's a profound misapplication of Wolff's Law and it ignores the foundational principle of the Hueter-Volkmann Law and confuses the distinct processes of appositional bone growth (widening/thickening) with interstitial growth (lengthening)
LSJL CANT significant increase your stature because:
- It violates the Hueter-Volkmann Law: Compressive forces on the growth plate retard rather than stimulate longitudinal growth
- It targets the wrong structure: The growth plates responsible for height are ossified in adults so they are completely unresponsive to any form of mechanical stimulation
- It confuses the effects of Wolff's Law: Any observable changes from lateral loading will be in cortical thickness and bone width not length
- It lacks a plausible biological mechanism: The theoretical claims regarding microfractures and stem cell differentiation do not translate into longitudinal bone elongation in humans and are contradicted by established mechanobiology
3. MECHANICAL + BIOLOGICAL CONTRADICTIONS OF LSJL
1. The Hueter-Volkmann Law
This law was established over a century ago and confirmed by countless studies in orthopedics and is the most direct refutation of LSJL. It states that "In a growing skeleton, increased static or sustained compression across a growth plate will slow or stop longitudinal growth, while tension (distraction) will accelerate it."Application: This principle is used by surgeons to correct deformities. EG:- vertebral body staples are placed to apply compression, deliberately slowing growth on one side of a vertebra to correct scoliosis. If compression stimulated growth then these implants would worsen the deformity
The LSJL Contradiction: LSJL applies sustained and lateral compression directly across the ends of the bone. So even in a skeletally immature person LSJL would not make them taller; it would stunt their growth. THIS SHIT MAY LEAD TO ANGULAR DEFORMITIES BTW, JFL.
2. Wolff's Law
This law describes how bone tissue adapts to mechanical loading by remodeling its internal and external structure to better resist future forces. It's often summarized as "bone responds to the loads placed upon it"Reality: Wolff's Law controls appositional bone growth which changes a bone's width / thickness and shape.
LSJL Misapplication: Proponents of LSJL argue that lateral clamping will stimulate growth. From a Wolff's Law perspective they are partially correct. A load applied to the epiphysis will induce a biological response, sure nigga. But the response is to strengthen the bone in the plane of the applied load.
LSJL Contradiction: If LSJL produced any skeletal change then it would be an increase in the width and density of the knee or ankle joint and not the length of the tibia or femur. This is literally just logic. Currently writing this, i'm wondering what even is the point of debunking such bullshit.
4. COLLAPSE OF MECHANISMS
1. The Microfracture Fallacy
Some early LSJL protocols involved literally tapping bones with a hammer to create microfractures and theorizing that the healing process would bridge the gap and make the bone longer. Like come on man.Reality: This is a LOW IQ interpretation of fracture healing. When a bone fractures the healing process involves the formation of a cartilaginous callus that bridges the gap before being remodeled into bone
LSJL Contradiction: A microfracture callus would span the fracture site in its original + broken position. It has no biological mechanism to elongate the bone spontaneously. The body’s priority is structural stability and not increased length. This "muh high IQ method" would only cause pain, inflammation and bone damage.
2. The Stem Cell Fluid Dynamics
A more sophisticated (but still WRONG, JFL) hypothesis suggests that compressing the epiphysis pressurizes the bone marrow forcing mesenchymal stem cells (MSCs) toward the growth plate to differentiate into new cartilageReality: Yes MSCs can respond to hydrostatic pressure the effect is local and context dependent. The idea that lateral clamping can generate a directional fluid flow that guides MSCs into a specific biological program to create new and organized growth plates is an retarded claim without any extraordinary evidence
LSJL Contradiction: The forces required to pressurize cancellous bone to that degree would be destructive. Also the growth plate is not a passive recipient of cells. It's a highly structured and hormonally regulated organ that gets fucked in adulthood. You cannot force MSCs to recreate an epiphyseal plate where one has been ossified lol
5. VERDICT ON HEIGHT GAIN
This is the simplest + most powerful refutation: longitudinal bone growth is a finite process that ends with epiphyseal plate closure. The growth plates are the only site of longitudinal growth.
In a Skeletally Mature Adult (closed GPs): The growth plates get replaced by solid bone
LSJL Contradiction: Proposing that LSJL can increase height in an adult is equivalent to proposing that compressing the ends of a solid steel pipe will make it longer, that shit just isnt possible
ONE MORE FUCKING POST ABOUT LSJL AND I WILL BAN YOU D DoorHandle5
