Summary
Tibia deficiencies require tailored surgical approaches. Through-knee amputation suits Kalamchi type I, while type II and III benefit from foot ablation, though prosthetic challenges may arise.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Limb Deformity Correction
Background:
- Longitudinal deficiency of the tibia is a rare congenital limb malformation.
- Treatment strategies vary based on the specific type and severity of tibial deficiency.
- Previous studies highlight the challenges in managing these complex cases.
Purpose of the Study:
- To review clinical and radiographic outcomes of patients with longitudinal tibial deficiency.
- To evaluate the effectiveness of different surgical management techniques.
- To identify potential complications and prosthetic challenges associated with each treatment approach.
Main Methods:
- Retrospective review of 15 patients (19 limbs) treated between 1981 and 2001.
- Classification of tibial deficiencies using the Kalamchi system (Type I, II, III).
- Analysis of surgical interventions including through-knee amputation, foot ablation, and tibiofibular synostosis.
Main Results:
- Ten limbs with Kalamchi type I deficiency underwent through-knee amputation.
- Five type II deficiencies were managed with foot ablation and tibiofibular synostosis, noting potential varus alignment and fibular prominence issues.
- Four type III deficiencies were treated by foot ablation, with potential proximal or distal tibiofibular instability requiring further surgery.
Conclusions:
- Surgical management of longitudinal tibial deficiency should be individualized based on Kalamchi classification.
- Through-knee amputation is a viable option for type I deficiencies.
- Foot ablation with tibiofibular synostosis for type II and III may lead to prosthetic complications requiring careful management.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
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...

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
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...

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.
