What is congenital tibial pseudarthrosis?
Congenital pseudarthrosis of the tibia is a shin bone fracture in children that has not healed. It normally presents before a child turns two years old.
What is pseudoarthrosis of tibia?
Content Area. Congenital pseudarthrosis of the tibia (CPT) refers to nonunion of a tibial fracture that develops spontaneously or after a minor trauma. A pseudarthrosis is defined as a “false joint” and is a break in the bone that fails to heal on its own.
What causes pseudarthrosis?
Causes. Pseudarthrosis occurs when bones fail to fuse with one another after spinal fusion surgery. Factors that reduce the ability of bone-producing cells (called osteoblasts) to produce new bone for fusion increase the risk of Pseudarthrosis.
What does pseudarthrosis mean?
What are the symptoms of pseudarthrosis? The symptoms of pseudoarthrosis are similar to those of osteoarthritis and include; lack of mobility, persistent pain, joint clicking and in some cases, redness and even fever.
What is Paraxial tibial Hemimelia?
Description: Tibial hemimelia has been referred to in the literature by many names, including paraxial tibial hemimelia, congenital deficiency or absence of the tibia, congenital longitudinal deficiency of the tibia, congenital dysplasia of the tibia and congenital tibial deficiency.
What are symptoms of pseudarthrosis?
The symptoms of pseudoarthrosis are similar to those of osteoarthritis and include; lack of mobility, persistent pain, joint clicking and in some cases, redness and even fever.
How is pseudarthrosis diagnosed?
Pseudarthrosis occurs when a spinal fusion surgery fails. Some people with this condition experience no symptoms; some people feel pain in their neck, back, arms or legs. Diagnosis of pseudarthrosis involves imaging tests of the spine. The treatment for pseudarthrosis is a second spinal fusion surgery.
What does Hemimelia mean?
Medical Definition of hemimelia : a congenital abnormality (as total or partial absence) affecting only the distal half of a limb.
What causes Hemimelia?
The exact cause of fibular hemimelia is unknown. A spontaneous genetic error occurs during limb bud development. This growth abnormality occurs during the development of the lower limb bud at six to eight weeks after conception.
How does pseudarthrosis occur?
Can pseudarthrosis be fixed?
Although the approach is contentious, several studies have shown high fusion rates and improved patient outcomes with posterior decompression and arthrodesis [12,16,26,61,64]. Treating pseudarthrosis posteriorly using iliac crest or local autograft and posterior wiring or lateral mass plating has been recommended [64].
What is fibula Hemimelia?
What Is Fibular Hemimelia? Children who have fibular hemimelia are born with a short or missing fibula (one of the two bones in the lower leg). Other bones in the leg, ankle, and foot can be affected too. Most children with fibular hemimelia (FIB-yoo-luhr heh-me-MEEL-yuh) have it in one leg, but some have it in both.
What does congenital pseudarthrosis of the tibia mean?
Congenital pseudarthrosis of the tibia is characterized by anterolateral deformity of the tibia and shortening of the limb. Its etiology remains unclear.
What is the diagnosis of posteromedial tibial bowing?
Posteromedial Tibial Bowing is a congenital condition thought to be a result of intrauterine positioning that typically presents with a calcaneovalgus foot deformity and leg length discrepancy. Diagnosis is made radiographically with xrays of the tibia.
Is the bowing of the tibial diaphysis congenital?
Definition A congenital bowing of the tibial diaphysis (anterolateral apex), associated with diaphyseal pseudoarthrosis. Pseudoarthrosis in not congenital, but in fact develops post-natally due to fracture non-union.
Are there any noninvasive treatments for tibia pseudarthrosis?
Unfortunately, none of invasive and noninvasive methods have proven their superiority. Surgical options such as intramedullary nailing, vascularized fibula graft, and external fixator, have shown equivocal success rate in achieving primary union although they are often associated with acceptable results.
