Ankle Joint01:10

Ankle Joint

2.4K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Knee Joint

2.9K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Summary

Temporomandibular joint (TMJ) ankylosis surgery using interpositional arthroplasty with vascularized temporalis fascia flap effectively restores mouth opening and prevents recurrence. Aggressive physiotherapy is crucial for optimal outcomes in TMJ ankylosis treatment.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthopedic Surgery
  • Regenerative Medicine

Background:

  • Temporomandibular joint (TMJ) ankylosis is a debilitating condition affecting mastication, speech, and appearance.
  • It is particularly prevalent in young children and requires careful surgical planning.
  • Treatment aims to restore joint function and prevent relapse.

Purpose of the Study:

  • To evaluate the efficacy of osteoarthrectomy and interpositional arthroplasty in treating TMJ ankylosis.
  • To assess the long-term outcomes and recurrence rates.
  • To highlight the role of vascularized temporalis fascia flap in preventing relapse.

Main Methods:

  • A series of 18 patients with TMJ ankylosis underwent osteoarthrectomy and interpositional arthroplasty.
  • Patients ranged from 5-57 years old, with both unilateral and bilateral cases.
  • Follow-up included assessment of mouth opening and physiotherapy adherence.

Main Results:

  • Successful mouth opening was achieved in all patients.
  • Early post-operative mouth opening ranged from 24-37 mm, with late results between 20-33 mm.
  • A minimum of 6 months of aggressive physiotherapy was emphasized.

Conclusions:

  • Interpositional arthroplasty with a vascularized temporalis fascia flap is a reliable method for TMJ ankylosis.
  • This technique effectively prevents recurrence and avoids issues associated with alloplastic materials.
  • The procedure offers a durable solution for TMJ ankylosis, improving patient function and quality of life.
