Randomized Controlled TrialBotulinum Toxin type A injections for patients with painful hallux valgus: a double-blind, randomized controlled study.
Hallux valgus (HV) related pain and disability remains a medical challenge to date. We have evaluated the therapeutic effect of intramuscular Botulinum Toxin type A (BTX-A) injection on painful HV in a double-blind randomized controlled trial. Sixteen patients having painful HV in at least one foot from the Department of Physical Medicine and Rehabilitation at a medical center in northern Taiwan have participated. ⋯ Pain reduction induced by BTX-A injection lasted for at least 6 months while that induced by NS lasted for only 1 month. In addition, patients in the BTX-A group showed greater improvement in pain score (p<0.001), disability score (p<0.05), and HV angle (p<0.05) than patients in the NS group. The results reflected that HV-related muscle injection of BTX-A resulted in a marked reduction in pain for up to 6 months.

Randomized Controlled TrialIs rehabilitation intervention during hospitalization enough for functional improvements in patients undergoing lumbar decompression surgery? A prospective randomized controlled study.
Rehabilitation has been reported to improve pain and disability for patients after lumbar surgery. However, studies to investigate the rehabilitation intervention for lumbar decompression surgery during hospitalization are scarce. The aim of this study was to examine outcomes of perioperative rehabilitation intervention for patients who underwent lumbar decompression surgery (LDS). ⋯ The findings of this study indicate that the rehabilitation intervention during hospitalization improves pain intensity as well as disability and quality of life, yet has limited effects on the functional performance over time up to six months post-surgery in patients who received LDS. The study suggest that rehabilitation interventions during hospitalization must include regular support for patient adherence to the intervention program and focus on task-oriented programs for lower extremities such as closed-chain exercises in functional postures.

Comparative StudyComparison of seeding methods for visualization of the corticospinal tracts using single tensor tractography.
To compare five different seeding methods to delineate hand, foot, and lip components of the corticospinal tract (CST) using single tensor tractography. ⋯ Whole brain seeding and then selecting the tracts that pass through two anatomically relevant ROIs can delineate more plausible hand and lip motor tracts than seeding from a single ROI. Foot motor tracts can be successfully delineated regardless of the seeding method used.

Preoperative MRI in neurovascular compression syndromes and its role for microsurgical considerations.
Neurovascular compression (NVC) in the posterior fossa is characterized by complex, three-dimensional (3D) neurovascular relationships at the root entry zones (REZ) and other parts of cranial nerves, resulting in syndromes such as trigeminal neuralgia (TN), hemifacial spasm, vertigo and glossopharyngeal neuralgia. Microvascular decompression (MVD) requires microsurgical experience and 3D orientation within the cisternal spaces to achieve adequate clinical results. The vascular structures in anatomical relation to the trigeminal nerve root at the lateral pontine aspect of the brainstem should be examined and maximally decompressed to minimize the risk of recurrent TN. Indication was traditionally based on clinical decisions, only. New MR techniques have become available, and their chances and potential impact should be evaluated in this study. ⋯ We show that high resolution MR images provide reliable and detailed information on corresponding intraoperative anatomy. Especially in unusual cases, the application of such MR techniques and preoperative evaluation may contribute to indication, planning, and also for teaching purposes.

Thoracic lateral extracavitary corpectomy for anterior column reconstruction with expandable and static titanium cages: clinical outcomes and surgical considerations in a consecutive case series.
Many surgical interventions have emerged as effective means of restoring mechanical stability of the anterior column of the spine. The lateral extracavitary approach (LECA) allows for broad visualization and circumferential reconstruction of the spinal column. However, early reports demonstrated significant complication rates, protracted operative times, and prolonged hospitalizations. More recent reports have highlighted concerns for subsidence, particularly with expandable cages. Our work seeks to describe a single-surgeon consecutive series of patients undergoing LECA for thoracic corpectomy. Specifically, the objective was to explore the surgical considerations, clinical and radiographic outcomes, and complication profile of this approach. ⋯ The LECA approach for anterior column reconstruction with static or expandable cages is an important surgical consideration with favorable surgical parameters and complication rates. Further, use of expandable cages may allow for reconstruction over a larger segment without increased risk of subsidence.
