Ankle Joint01:10

Ankle Joint

3.7K
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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

9.7K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Traumatology

Background:

  • Current acromioclavicular (AC) joint reconstruction methods have limitations, including fixation loss and complications.
  • These limitations hinder the widespread adoption of existing surgical techniques for AC joint dislocations.

Purpose of the Study:

  • To evaluate the long-term clinical and radiologic outcomes of a novel surgical technique for AC joint reconstruction.
  • The technique utilizes a closed-loop double Endobutton device for both acute and chronic dislocations.

Main Methods:

  • A case series (Level of evidence, 4) involving 35 patients with Rockwood type III or greater AC joint dislocations.
  • Surgical reconstruction included AC joint capsule imbrication, deltotrapezial fascia repair, and biological bridging of the coracoclavicular (CC) interval via coracoacromial (CA) ligament transfer or primary CC ligament repair.
  • Follow-up data was obtained for 31 patients, with a mean follow-up of 5.2 years.

Main Results:

  • The surgical construct demonstrated high stability, with only 1 failure in 31 patients.
  • Mean coracoclavicular (CC) interval difference was 1.1 mm, with 87% of patients showing <2 mm difference.
  • Excellent functional outcomes were reported: mean Constant score of 98, mean University of California, Los Angeles Shoulder Rating Scale score of 34, and mean American Shoulder and Elbow Surgeons Shoulder Score of 98.
  • Follow-up MRI in 10 patients showed dense scar tissue, indicating robust healing. No perioperative complications were reported.

Conclusions:

  • The closed-loop double Endobutton technique offers excellent and durable long-term results for AC joint reconstruction.
  • This method effectively eliminates the risk of knot slippage or device breakage, ensuring construct integrity.
  • The technique yields superior outcomes compared to historical non-surgical results and is recommended for both acute and chronic AC joint dislocations.
