C1-C2 Posterior Fixation: Indications, Technique, and Results
The atlantoaxial motion segment, which is responsible for half of the rotational motion in the cervical spine, is a complex junction of the first (C1) and second (C2) cervical vertebrae….
Subaxial Cervical and Cervicothoracic Fixation Techniques—Indications, Techniques, and Outcomes
The subaxial and cervicothoracic junction is a relatively difficult area for spine surgeons to navigate. Because of different transitional stressors at the junction of the smaller cervical vertebrae and the…
Occipitocervical Fusion
The evolution of occipitocervical fixation and new rigid universal screw-rod construct technology has allowed secure anchorage at each level of the occipitocervical junction with the elimination of rigid external orthoses….
Implantation of Orthobiologic, Biodegradable Scaffolds in Osteochondral Repair
The treatment of articular cartilage lesions is complicated, but novel tissue engineering approaches seem to improve the outcome. A tissue engineering approach is less invasive and reduces surgical time, periosteal…
Clinical Relevance of Scaffolds for Cartilage Engineering
The repair of articular cartilage defects in patients’ knees presents a particular challenge to the orthopedic surgeon because cartilage lacks the ability to repair or regenerate itself. Various cartilage repair…
Epidemiology, Pathogenesis, and Imaging of Arthritis in Children
Juvenile idiopathic arthritis is a broad term used to describe a series of chronic arthritis occurring in children younger than 16 years of age. Even though the cause is not…
“One Step” Treatment of Juvenile Osteochondritis Dissecans in the Knee: Clinical Results and T2 Mapping Characterization
Osteochondritis dissecans (OCD) is an increasingly common cause of knee pain and dysfunction among skeletally immature and young adult patients. An ideal treatment strategy with an optimal surgical technique to…
Acute Traumatic and Sports-Related Osteochondral Injury of the Pediatric Knee
Adolescents are predisposed to osteochondral (OC) injuries in the knee. The medial facet of the patella, the femoral trochlea, and the lateral femoral condyle are the most common sites of…
Imaging of Osteochondritis Dissecans
Osteochondritis dissecans (OCD) is a localized process that affects the subchondral bone and can progress to the overlying articular cartilage. The cause of this lesion remains elusive. With the vague…
Effect of Exercise on Articular Cartilage
This review primarily focuses on how the macromolecular composition and architecture of articular cartilage and its unique biomechanical properties play a pivotal role in the ability of articular cartilage to…
