Indications – Overview
Early resuming of sporting activities, like cycling, even on the same day as the surgery.Read More
Unilateral lengthening deals with congenital and hereditary diseases involving the femur, humerus and tibia as well as resolving trauma to these areas.
STATURE: DWARFISM AND CONGENITAL SHORT STATURE
Dwarfism describes stature that is below that of the ‘typical’ average height of the population.
The population that is considered ‘normal’ sits within a range of +3 standard deviations (SD) and – 3 SD, representing 99.5% of the population.
Dwarfism represents a group of people that fall far below this range. Those who are too tall to be considered people with dwarfism, but outside the ‘normal’ height range are described as people of ‘short stature’, who are labelled ‘cosmetic lengthening’ candidates.
|STATURE||Average and Standard Deviation (cm)||Female||Male|
|-1 SD (68% of the population is > this stature)||160||172.5|
|-2SD (95% of the population is > this stature)||156||169|
|– 3SD (99.7% of the population is > this stature)||153||166|
|Dwarfism||+2SD (95% of the dwarf population is < this stature)||136||142|
‘Cosmetic’ generally means that there is no pathological need for surgery, (‘O’ or ‘X’ shaped legs are associated issues here) which needs to be determined before any procedure.
BONE DISEASES AND MALALIGNMENTS
Anomalies and deformities related to bone structure or ‘architecture’, such as alignment or axis deformations where ‘O’ or ‘X’ shaped legs are present, are often observed. Length anomalies (bilateral shortening, as with dwarfism and congenital short stature, and unilateral discrepancy) and presence of bone dysplasia are also issues found within bone structure and quality.
In joints, deformities can range from the full or partial absence of hip, knee, ankle or foot joints to axis deviations and soft tissue lesions.
Dr Guichet’s techniques allow for the corrections, reconstruction and lengthening, as well as addressing missing knee ligaments and problems during growth.
In cases of associated deformations, additional diseases can form (congenital short femur, tibia agenesis, fibular hemimelia, club-foot etc.) Sometimes shortenings of up to 30 cm can occur, and foot problems such as metatarsus adductus, flat foot or hallux valgus come to light.
