Review Comparative Study
A systematic review of comparative studies on bone graft alternatives for common spine fusion procedures.
The increased prevalence of spinal fusion surgery has created an industry focus on bone graft alternatives. While autologous bone graft remains the gold standard, the complications and morbidity from harvesting autologous bone drives the search for reliable and safe bone graft substitutes. With the recent information about the adverse events related to bone morhogenetic protein use, it is appropriate to review the literature about the numerous products that are not solely bone morphogenetic protein. ⋯ The recommendations for use of bone graft substitutes and bone graft extenders are based on the strength of the studies and given a grade.

The aim of this article has been to analyze the clinical and radiological data suggesting tuberculous vertebral osteomielitis (TVO), and then discuss the steps to be followed to achieve an aetiological diagnosis. ⋯ All patients with subacute inflammatory back or neck pain showing suggestive radiological findings should be studied to rule out TVO. If there is no clear evidence of tuberculosis from another location or indication for surgery, a percutaneous vertebral biopsy should be performed. When TVO is suspected, all spinal or paravertebral tissue samples should be sent simultaneously to pathology and microbiology laboratories for appropriate processing.

To provide an overview of the tuberculosis (TB) and multi-drug resistant tuberculosis (MDR-TB) in the WHO European Region and evolution of public health response with focus on extra-pulmonary tuberculosis and Pott's disease. ⋯ There is a need to further analyze country data to document the extent of Pott's disease and develop specific guidelines for timely diagnosis and treatment of Pott's disease.

The most dreaded neurological complications in TB spine occur in active stage of disease by mechanical compression, instability and inflammation changes, while in healed disease, these occur due to intrinsic changes in spinal cord secondary to internal salient in long standing kyphotic deformity. A judicious combination of conservative therapy and operative decompression when needed should form a comprehensive integrated course of treatment for TB spine with neurological complications. The patients showing relatively preserved cord with evidence of edema/myelitis with predominantly fluid collection in extradural space on MRI resolve on non-operative treatment, while the patients with extradural compression of mixed or granulomatous nature showing entrapment of spinal cord should be undertaken for early surgical decompression. ⋯ The internal kyphectomy is indicated for paraplegia with healed disease. These cases are bad risk for surgery and neural recovery. The best form of treatment of late onset paraplegia is the prevention of development of severe kyphosis in initial active stage of disease.

Review Historical Article
Historical aspects of Pott's disease (spinal tuberculosis) management.
Spinal tuberculosis has existed in human beings since the ascent of man on earth. Historically, the management has progressed from regional orthodox therapies to the current, more effective, drugs. ⋯ Broad conclusions based upon the published data and personal observations (1959-2011) are summarized as follows: If diagnosis is made at predestructive stage and the patient is treated by standard drugs, the infection would heal in about 95 % patients without significant deformities and complications. Neural complications are still encountered in general hospital outpatients. Diagnosis and treatment at early stages would resolve the neurology without operation in about 40 % of cases. Nearly 60 % of patients would require to be operatively decompressed without jeopardizing mechanical stability. However, despite current treatment approximately 8 % of tuberculous paraplegics do not recover functionally. Immunocompromised state and multidrug resistance to standard drugs (8 to 10 %) are the current (and future) challenges to the doctors and the society.
