Historically, childhood leg deformities from diseases like rickets and polio were treated with lifelong orthotics. The 19th century saw surgical innovations like osteotomy and a shift towards subcutaneous procedures to combat infection before modern antiseptics.
Area of Science:
- Orthopaedic Surgery
- Pediatric Deformity Correction
- History of Medicine
Context:
- Past treatments for childhood leg deformities (rickets, polio, tuberculosis) relied heavily on orthotics.
- 19th-century orthopaedic surgery introduced procedures like tenotomy, osteoclasis, osteotomy, joint excision, and arthrodesis.
- Early surgical approaches aimed to manage wound suppuration before the advent of Lister's antiseptic principles.
Purpose:
- To review historical treatments for pediatric leg deformities.
- To highlight the evolution of surgical techniques in orthopaedics.
- To understand the development of subcutaneous surgery in the pre-antiseptic era.
Summary:
- Rickets, poliomyelitis, and tuberculosis were primary causes of pediatric leg deformities and shortening.
- Orthotics were a cornerstone of treatment and rehabilitation, often for life.
- 19th-century surgeons developed various operative procedures, often utilizing a subcutaneous approach to mitigate infection risks.
Impact:
- Demonstrates the historical progression of orthopaedic interventions for pediatric limb deformities.
- Illustrates the challenges and innovations in surgical practice before modern aseptic techniques.
- Provides context for the development of current orthopaedic surgical standards and treatments.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Muscles that Move the Leg
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...
Muscles of the Leg that Move the Foot and Toes
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.
