What is condylar fracture?
condyle neck fracture, which occurs at the inferior attach area of the joint capsule, refers to an area that becomes narrow from the condyle head. It is an extracapsular fracture as it is not included in the joint capsule, and exists at the inferior attach area of the lateral pterygoid.
What are the classifications of condylar fracture?
In the past, there have already been multiple attempts to classify the fractures of the mandibular condylar process according to their anatomical position. Köhler distinguished fractures of the head, subcondylar fractures, as well as medium and deep condylar neck fractures at the level of the sigmoid notch.
Which condylar fracture cause ankylosis?
Intracapsular condylar fracture of the mandibular: Our classification and open treatment experience. Sagittal condylar ICFs (type B) have been found to be more likely to cause ankylosis.
Where are condyles found?
knee joint
A condyle (/ˈkɒndəl/ or /ˈkɒndaɪl/; Latin: condylus, from Greek: kondylos; κόνδυλος knuckle) is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. It is one of the markings or features of bones, and can refer to: On the femur, in the knee joint: Medial condyle.
How are condylar fractures diagnosed?
Routine radiological investigations that aids in the diagnosis of condylar fracture are:
- Posteroanterior skull projection or Reverse Towne’s (Figure 7)
- Oblique-lateral X-ray.
- Orthopantomographic radiograph (Figure 8)
- TMJ tomography.
- Waters projection or Para nasal sinus view.
- Clementschitsch view or occipital.
What is TMJ ankylosis?
Summary. Temporomandibular joint ankylosis is defined as bony or fibrous adhesion of the anatomic joint components accompanied by a limitation in opening the mouth, causing difficulties with mastication, speaking and oral hygiene as well as inadvertently influencing mandibular growth.
How common is TMJ ankylosis?
TMJ ankylosis was detected in significant numbers in a population-based door to door survey (the overall prevalence of TMJ ankylosis was 0.46 per 1000 in the 3-15 years’ age group). Birth/childhood trauma was the major causative factor.
Is condyle a bone or cartilage?
Three bones make up the knee joint – the femur, the tibia and the patella. The femur (thigh bone) is the largest bone in the body and extends from the hip to the knee where it ends in structures known as condyles that are covered in cartilage.
What is the function of condyle?
Condyle – Refers to a large prominence, which often provides structural support to the overlying hyaline cartilage. It bears the brunt of the force exerted from the joint. Examples include the knee joint (hinge joint), formed by the femoral lateral and medial condyles, and the tibial lateral and medial condyles.
What bones have a condyle?
Condyle refers to a rounded protuberance at the end of a bone, which articulates the bone with another bone. Therefore, condyle is considered as a part of a joint. Femur refers to the thigh bone. On the femur, two types of condyles occur in the knee joint: medial and lateral condyle.
How much force does it take to fracture a jaw?
Like other bones in the body, the mandible fractures at sites of tensile strain. The amount of force required to fracture the mandible is put at between 44.6 –74.4 Kg/m2.
What is the best way to determine if there is a mandible injury?
Diagnosing Mandible Fractures After a physical check of your jaw and face, you’ll undergo a radiograph to detect jaw fracture(s) resulting from the injury. Maxillofacial radiologists – doctors who specialize in reading dental radiographs – access the presence and severity of cracks, splits, or complete breaks.
What is false ankylosis?
A false ankylosis is caused by extracapsular pathology that limits normal jaw movement. 2. Causes may include fibrous adhesions between the zygomatic arch and mandible secondary to fracture, infection or neoplasia. A true ankylosis is from intracapsular pathology and fibrosis.
How do you treat TMJ ankylosis?
Surgery in TMJ ankylosis treatment entails complete ankylotic block removal and subsequent arthroplasty, possibly with autologous graft between articular surfaces (skin, 9,10 rib cartilage, 11,12 temporal muscle 13,14) or heterologous graft (Silastic 15) to fully restore the anatomic structure.
Which bones have condyle?
It is one of the markings or features of bones, and can refer to:
- On the femur, in the knee joint: Medial condyle.
- On the tibia, in the knee joint: Medial condyle.
- On the humerus, in the elbow joint:
- On the mandible, in the temporomandibular joint:
- On the occipital bone, in the atlanto-occipital joint:
What is the weakest part of the mandible?
The ‘weakest’ region of the mandible that fractures in one site only is the angle region and of the mandible that fractures in more than one site is the condyle region. The ‘weakest’ site of the dentulous mandible is the condyle region and of the edentulous mandible the molar region.
