Summary
Conservative treatments for lower limb discrepancy have low long-term acceptance. Surgical bone lengthening, evolving over 100 years, offers advanced solutions for complex deformities, improving patient outcomes.
Area of Science:
- Orthopedic surgery
- Biomechanical engineering
- Regenerative medicine
Background:
- Lower limb discrepancy can be managed conservatively, but acceptance is limited.
- Epiphysiodesis is effective for specific deformities, but late presentation or complex cases require advanced techniques.
Purpose of the Study:
- To review the historical development and current state of surgical bone lengthening techniques.
- To discuss the evolution from early distraction methods to modern multi-planar deformity correction.
- To highlight advancements in limb lengthening technology and their impact on patient care.
Main Methods:
- Historical review of surgical bone lengthening techniques.
- Discussion of Ilizarov's contributions (callotasis) and hexapod technology (Taylor Spatial Frames).
- Comparison of unilateral fixation, internal nails, and their indications.
Main Results:
- Surgical bone lengthening has evolved significantly over 100 years.
- Modern techniques like Taylor Spatial Frames enable precise multi-planar correction.
- Minimally invasive nails offer improved rehabilitation and patient comfort for less complex cases.
Conclusions:
- Limb lengthening, especially for complex deformities, requires careful patient selection and surgical expertise.
- Advanced technologies have improved precision and outcomes in limb reconstruction.
- The choice of method depends on deformity complexity, patient factors, and surgeon experience.

01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
