The osteoporosis prevalence in population is age related. The aim of this single-center observational study was evaluate the middle- to long-term performance of cement (PMMA) augmented fenestrated pedicle screws in elderly patients with thoraco-lumbar compressive fractures by osteoporosis. ⋯ Fenestrated screws with PMMA augmentation offers a possibility to treat patients with reduced bone quality due to severe osteoporosis.

An incidental durotomy is a common complication of spinal surgery. Its treatment remains challenging, especially in endoscopic procedures. The objective of this study is to describe a technique for endoscopic dural closure which is safe and effective. ⋯ Dural closure with an autologous muscle graft in combination with fibrin sealant patch is a fast, safe and alternative technique for the management of dural tear in microendoscopic surgery.

The aim of the present study was to examine the natural history in patients with lumbar spinal stenosis. The incidence of surgery for this condition has increased considerably during the past decades in spite of a fairly favorable natural history in previous studies. ⋯ The natural history of LSS with moderate symptom levels rarely shows symptom deterioration over a median of 3.3 years; in fact, a slight improvement of symptoms was seen at group levels. The treatment decision was revised for 7%, and for the rest an increase in pain was seen in 10-13%. The results support reluctance towards surgery, if the symptom levels are tolerable for the patients.

Multicenter Study Observational Study
Criteria for failure and worsening after surgery for lumbar disc herniation: a multicenter observational study based on data from the Norwegian Registry for Spine Surgery.
In clinical decision-making, it is crucial to discuss the probability of adverse outcomes with the patient. A large proportion of the outcomes are difficult to classify as either failure or success. Consequently, cutoff values in patient-reported outcome measures (PROMs) for "failure" and "worsening" are likely to be different from those of "non-success". The aim of this study was to identify dichotomous cutoffs for failure and worsening, 12 months after surgical treatment for lumbar disc herniation, in a large registry cohort. ⋯ The criteria with the highest accuracy for defining failure and worsening after surgery for lumbar disc herniation were an ODI percentage change score <33% for failure and a 12-month ODI raw score >48. These cutoffs can facilitate shared decision-making among doctors and patients, and improve quality assessment and comparison of clinical outcomes across surgical units. In addition to clinically relevant improvements, we propose that rates of failure and worsening should be included in reporting from clinical trials.
