Review Meta Analysis
Systematic review and meta-analysis of minimally invasive transforaminal lumbar interbody fusion rates performed without posterolateral fusion.
The need for posterolateral fusion (PLF) in addition to interbody fusion during minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) has yet to be established. Omitting a PLF significantly reduces overall surface area available for achieving a solid arthrodesis, however it decreases the soft tissue dissection and costs of additional bone graft. The authors sought to perform a meta-analysis to establish the fusion rate of MIS TLIF performed without attempting a PLF. ⋯ Either polyetheretherketone (PEEK) or allograft interbody cages were used in all patients. Overall fusion rate, confirmed by bridging trabecular interbody bone on CT scan, was 94.7%. This meta-analysis suggests that MIS TLIF performed with interbody bone grafting alone has similar fusion rates to MIS or open TLIF performed with interbody supplemented with posterolateral bone grafting and fusion.

Historical perceptions regarding the severity of traumatic spinal cord injury has led to considerable disparity in triage to tertiary care centers. This article retrospectively reviews a large regional trauma database to analyze whether the diagnosis of spinal trauma affected patient transfer timing and patterns. The Pennsylvania Trauma database was retrospectively reviewed. ⋯ However subsets analysis revealed that spine trauma patients had the greatest transit times. Present research trials for spinal cord injuries suggest earlier intervention may lead to improved recovery. Therefore, it is important to focus on improvement of the transportation triage system for traumatic spinal patients.

It remains unknown whether aggressive microdiscectomy (AD) provides a better outcome than simple sequestrectomy (S) with little disc disruption for the treatment of lumbar disc herniation with radiculopathy. We compared the long term results for patients with lumbar disc herniation who underwent either AD or S. The patients were split into two groups: 85 patients who underwent AD in Group A and 40 patients who underwent S in Group B. ⋯ We argue that reherniation rates are much lower over the long term when AD is used with microdiscectomy. AD increases back pain for a short time but does not change the long term quality of life. To our knowledge this is the first study with a very long term follow-up showing that reherniation is three times less likely after AD than S.

Subsidence after anterior cervical reconstruction using a titanium mesh cage (TMC) has been a matter of debate. The authors investigated and analyzed subsidence and its effect on clinical and radiologic parameters after cervical reconstruction using a TMC for degenerative cervical disease. Thirty consecutive patients with degenerative cervical spine disorders underwent anterior cervical corpectomy followed by reconstruction with TMC. ⋯ Anterior cervical reconstruction using TMC and plating in patients with cervical degenerative disease provides good clinical and radiologic outcomes. Cage subsidence occurred frequently, especially at the posterior part of the cage. Despite the prominent posterior subsidence of the TMC, SA and CSA were improved on final follow-up radiographs, suggesting that posterior subsidence may contribute to cervical lordosis.

To our knowledge, studies concerning the prevalence and burden of primary headache in China are limited to specific regions without comparison of different districts. A survey in a different area with similar climate and culture may enhance our knowledge of the factors causing primary headache and the burden of headache. We conducted a 1 year survey on the prevalence and burden of primary headache in the Chinese provinces of Guangdong and Guangxi. ⋯ The 1 year prevalence of primary headache was 22.6% (84/372) in Guangdong and 41.2% (75/182) in Guangxi (p<0.001). The average financial burden of primary headache is 2.1% and 3.7% of the mean household income in Guangdong and Guangxi, respectively (p=0.001). The district with lower economic status had a higher prevalence of primary headache, and inevitably bears a heavier burden even with the same disease cost.
