Pedicle screw augmentation with polyethylene tape: a biomechanical study in the osteoporotic thoracolumbar spine.
Biomechanical study using human thoracolumbar spines. ⋯ Pedicle screws that are inserted into the osteoporotic thoracolumbar spine and augmented by Nesplon tape applied sublaminar or subpars provide firmer fixation of the screws and a stiffer pedicle screw/rod construct than the same construct without augmentation by tape.

Normal functional range of motion of the lumbar spine during 15 activities of daily living.
Prospective clinical study. ⋯ By quantifying the amounts of lumbar motion required to execute a series of simulated ADLs, this study indicates that most individuals use a relatively small percentage of their full active ROM when performing such activities. These findings provide baseline data that may allow clinicians to accurately assess preoperative impairment and postsurgical outcomes.

Case ReportsRetroperitoneal lymphatic cyst formation after anterior lumbar interbody fusion: a report of 3 cases.
Case report. ⋯ If this rare complication occurs the primary intervention should be laparoscopic fenestration because of the high recurrence rate of other treatment modalities.

Transthoracic surgical treatment for centrally located thoracic disc herniations presenting with myelopathy: a 5-year institutional experience.
Retrospective review. ⋯ Thoracotomy for treatment of centrally located thoracic disc herniations is associated with improvement in or stabilization of myelopathic symptoms in the majority of patients with an acceptable rate of complications. Interestingly, most patients with weakness improved in strength (12/16, 75%), no patients with normal strength developed new weakness (10/10, 100%), and only 2 patients had new weakness noted postoperatively (7.4%).

Impact of cement leakage into disks on the development of adjacent vertebral compression fractures.
A retrospective study assessing new adjacent vertebral compression fracture (VCF) after percutaneous vertebroplasty (PV). ⋯ PV is a simple and effective, but not risk-free or complication-free procedure for the treatment of osteoporotic VCF. Patients undergoing PV should be informed of the possibility of new adjacent fractures and the higher risk if cement leaks into the disk.
