Legg - Calve - Perthes disease is a pathologic process that affect the development of the child ’s hip.1Although doctors know that it is produced by sterile necrosis of the femoral head , the cause that origin such mortification is really unknown .
ceremonious radioscopy does not admit an other diagnosis , so more advance diagnostic technique are involve for diagnosis of Legg - Calve - Perthes .
The moment in which the diagnosis of Legg - Calve - Perthes is made and , consequently , the point of affectedness in which the coxa is at that present moment , determines the handling to be applied and the complications that the patient may develop in the time to come .
Radiographic images are the most uncouth method acting to pop out the study of a painful presentment of the hip or pelvis , on suspicion of legg - calve - perthes or other pathology , as it is a simple , evenhandedly accessible and easy to interpret method . In the study of legg - calve - perthes , anteroposterior and lateral images should be taken in the place of Lauenstein ( “ in a frog lieu ” ) .
What Are The Stages Of Legg-Calve-Perthes Disease?
The Legg - Calve - Perthes consists of 4 stages : the first consists of lack of parentage supply to the femoral head , then the physical structure will absent the bushed bone cells and put back them with raw and healthier bone cellular telephone , in the next stage of Legg - Calve - Perthes the femoral head continues taking its rounded shape with new bone tissue . last , normal bone cell supplant fresh bone cells .
From the radiological point in time of scene , the process of ischemia and subsequent bone regeneration has been divided into several stages that reveal the anatomical changes of the femoral head and cervix . The recognition of the phase in which the process is locate has therapeutic and prognostic grandness .
Initial or Necrosis Phase or Stage of Legg-Calve-Perthes
The vascular provision and osseous tissue necrosis are interrupted . At this Legg - Calve - Perthes stage , the femoral psyche is very vulnerable to the forces acting on it.2
Fragmentation Phase or Stage of Legg-Calve-Perthes
A cognitive operation of reabsorption of the necrotic bone begin in this microscope stage of Legg - Calve - Perthes.2
Reossification Phase or Stage of Legg-Calve-Perthes
The denseness moves in the opposite way . The epiphysis is invade by vessels , the slow islets are reabsorbed and rarefaction ( it means to the lessening of density ) bone tissue is formed and then trabeculated . mending get down with the disappearance of metaphyseal osteolysis . Osteolysis is define as the process of abrasion and step-down of one or more areas of a bone .
Final or Healing Phase or Stage of Legg-Calve-Perthes
The complete successor of the necrotic bone with freshly organize ivory occurs in this stage of Legg - Calve - Perthes . The newly formed os has a weaker consistency so it can be remodeled so that the morphology of the femoral head adapts to the shape of the cup or not . This summons will not be definitive until the remnant of ivory maturation . Since the final result can be that of a deform femoral foreland , this phase can also be called the residuary disfigurement phase .
The duration of each Legg - Calve - Perthes stage is very variable , but in worldwide , the level of necrosis and atomization live about 6 months , the period of reosification from 18 months to 3 years and the final or healing form until bone maturation . For other experts , the fragmentation phase live approximately one twelvemonth and the reossification form lasts from 3 to 5 yr .
The main drawback of conventional skiagraphy is its ineffectiveness for the former diagnosing of bone necrosis . But once the osseous changes are visible , this will be very utilitarian for sort and monitoring the disease , focus the type of treatment and establishing a medical prognosis .
Evolution and Prognosis of Legg-Calve-Perthes
Legg - Calve - Perthes is a ego - limiting disease , because of its born development is towards healing . In primary care , if doctors suspect that are facing a Legg - Calve - Perthes disease , they should do checkup every 3 or 4 months because some case develop unfavorably and leave severe sequelae in maturity , mainly hip joint osteoarthritis , since the remodeling capacity of the femoral head with the acetabulum stop around 8 years and from this age there is hardly any king of remodeling .
Although 80 % of patients affect by the Legg - Calve - Perthes have a good evolution until the 4th 10 of lifetime , between the fourth and 5th ten there is a substantial risk of rise hiposteoarthritis , and in the 6th decade of life , one-half of the patients require the use of a hip prosthesis .
