The prevalence of indications and contraindications to cervical total disc replacement.

Background Context: Although the prevalence of indications and contraindications to lumbar total disc replacement (TDR) has been evaluated, no study to date has quantified the potential candidacy for cervical disc replacement in practice.

Purpose: To report the potential candidacy rate for cervical TDR from both an academic and private practice spine surgery setting.

Study Design/setting: Retrospective case series.

Posterior cervical arthrodesis for subacute odontoid fracture in a patient with osteopetrosis: case report.

Study Design: A case of subacute odontoid fracture in a patient with osteopetrosis treated with posterior cervical arthrodesis using transarticular screws and interspinous wiring.

Objectives: To report the first successful cervical arthrodesis in a patient with osteopetrosis and to highlight the potential perioperative pitfalls in this rare surgical population.

Summary Of Background Data: Osteopetrosis is a group of skeletal dysplasias characterized by osteoclast dysfunction, impaired bone resorption, and poor bone remodeling.

Intramedullary injection of contrast into the cervical spinal cord during cervical myelography: a case report.

Study Design: A case of iatrogenic intramedullary contrast injection during a C1-C2 cervical myelography is reported.

Objective: To investigate the occurrence of iatrogenic intramedullary contrast injection during a current C1-C2 cervical myelography.

Summary Of Background Data: Intramedullary injection of contrast is a rare but serious complication of C1-C2 cervical myelography that has not been reported since the widespread use of magnetic resonance imaging and the NASCIS III study protocol.

Tuberoplasty: creation of an acromiohumeral articulation-a treatment option for massive, irreparable rotator cuff tears.

This article reports the results of treatment for irreparable tears of the rotator cuff with a new procedure that we have termed a tuberoplasty. The tuberoplasty procedure involves removal of exostoses on the humerus followed by reshaping of the greater tuberosity to create a smooth, congruent acromiohumeral articulation. The coracoacromial ligament is preserved, and an acromioplasty is not performed.
