We cannot definitively conclude that the stress fracture occurred through a well healed construct with no pseudarthrosis
, given that the fracture occurred sometime between Ave and 11 months post-operatively and we do not have a CT scan during this time period to verify fusion.
CT is also useful in demonstrating the spinal canal and its alignment and is capable of detecting infection and pseudarthrosis (12) (Figure 8).
compared CT images with reoperation findings in symptomatic pseudarthrosis patients and reported that CT was not reliable in identifying these patients.
can occur as a result of a recurrence of instability and clinical symptoms, we decided to insert an additional screw, thereby reintroducing an old method described by Magerl.
2-4) Abnormal motion may lead to an osteophytic spur at the pseudarthrosis
, which may also impinge on the cuff.
The Slimplicity Solo system is intended for anterior cervical fixation to the cervical spine C2-C7 for the following indications: degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudarthrosis
, failed previous fusion, spondylolisthesis, and spinal stenosis.
Prolonged immobilization and extended periods of non-weightbearing (in some cases up to four months) are necessary to prevent pseudarthrosis
For over five years, Dornier has pioneered this type of therapy for the treatment of plantar fasciitis, tennis and golf elbow, shoulder tendonitis, Achilles tendonitis, patellar tendonitis and pseudarthrosis
The system is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies); trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudarthrosis
, and/or failed previous fusions.
Screw fixation for odontoid non-union still remains controversial because direct odontoid fixation is associated with a high rate of complications; a 24% incidence of major complication has been reported (11,14,20,22); the incidence of malreduction as 19%, and pseudarthrosis
as 12%, and, although infrequent, there are instances of implant failure reported in the literature.
degenerative scoliosis, kyphosis, and/or lordosis), (5) fracture, (6) pseudarthrosis
, (7) tumor resection, and/or (8) failed previous fusion.
(usually painless) and CTS have also been reported.
