Bones of the Lower Limb: Femur and Patella

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...

Summary

The modified quadrangular Le Fort I osteotomy (MQLI) offers stable skeletal results for midface deficiency. This technique shows promising soft tissue improvements, particularly in the cheek profile, without requiring malar advancement.

Area of Science:

Oral and Maxillofacial Surgery
Orthognathic Surgery
Craniofacial Surgery

Background:

Skeletal class III malocclusion with midface deficiency often requires complex surgical correction.
Conventional Le Fort I osteotomy is a standard procedure, but modifications are explored for improved outcomes.
Evaluating soft tissue changes and skeletal stability is crucial for assessing surgical techniques.

Purpose of the Study:

To evaluate the soft tissue changes and skeletal stability of the modified quadrangular Le Fort I osteotomy (MQLI).
To compare MQLI with the conventional Le Fort I osteotomy (LFI) in patients with midface deficiency and class III malocclusion.

Main Methods:

A comparative study involving 20 patients undergoing MQLI and 20 patients undergoing LFI for maxillary advancement and mandibular setback.
Cephalometric radiographs were taken preoperatively, immediately postoperatively, and at >6 months postoperatively.
Analysis of soft tissue (cheek line, perinasal areas) and skeletal movements, including stability.

Main Results:

No significant differences in skeletal characteristics or surgical changes between MQLI and LFI groups.
Both MQLI and LFI demonstrated similar maxillary and mandibular skeletal stability.
MQLI showed a significant increase in the cheek profile angle (3.5°) compared to LFI (2.1°), with more anterior soft tissue movement in MQLI.

Conclusions:

MQLI is an efficient and stable surgical method for correcting maxillary and infraorbital hypoplasia.
The technique improves soft tissue contours, particularly the cheek profile, without necessitating malar advancement.
MQLI shows particular benefit for Asian patients with midface deficiency.
