Bones of the Lower Limb: Tibia and Fibula01:10

Bones 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...

Changes 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...
Bones of the Lower Limb: Femur and Patella01:16

Bones 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...

Summary

Predicting surgical outcomes for late-onset tibia vara using hemiepiphyseodesis is challenging. Preoperative factors like age and deformity severity offer limited predictability for the amount of correction achieved.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Limb deformity correction

Background:

  • Late-onset tibia vara presents variable correction outcomes with hemiepiphyseodesis.
  • Predicting the degree of correction is crucial for effective treatment planning.

Purpose of the Study:

  • To identify preoperative factors that predict the amount of correction achievable with tibial and/or femoral hemiepiphyseodesis.
  • To improve surgical decision-making for late-onset tibia vara.

Main Methods:

  • Retrospective and prospective evaluation of 53 patients (67 knees) treated with hemiepiphyseodesis.
  • Correlation of correction amount with preoperative factors: age, body weight, and deformity degree.

Main Results:

  • Tibial hemiepiphyseodesis yielded an average correction of 9 degrees (range: -6 to 33 degrees).
  • Femoral hemiepiphyseodesis averaged 8 degrees of correction (range: 0-19 degrees).
  • Younger age and lesser deformity weakly predicted greater tibial correction; no factors predicted femoral correction.

Conclusions:

  • Hemiepiphyseodesis for late-onset tibia vara provides unpredictable correction amounts.
  • Preoperative factors are unreliable for predicting outcomes.
  • Osteotomy offers more predictable realignment, necessitating careful consideration of procedure risks and benefits.
