The protective role of dynamic stabilization on the adjacent disc to a rigid instrumented level. An in vitro biomechanical analysis.
To assess the changes of intradiscal pressure at the bridged and at the adjacent levels to a lumbar two-level hybrid instrumentation. ⋯ The raise of intradiscal pressure at the adjacent segment to a rigid instrumented segment can be reduced when the rigid construct is augmented with a dynamic stabilization device. Hybrid constructs might have a possible protecting role preventing the occurrence of degenerative disc changes at the adjacent segment to a rigid instrumented level. Augmentation with a dynamic stabilization device might protect the disc above a rigid rod pedicle screw construct.

Randomized Controlled Trial Multicenter StudyClinical assessment of a CMC/PEO gel to inhibit postoperative epidural adhesion formation after lumbar discectomy: a randomized, control study.
To evaluate effectiveness of carboxymethylcellulose/polyethylene oxide (CMC/PEO) gel in improving clinical outcomes after the first-time lumbar discectomy. ⋯ The results demonstrated that CMC/PEO gel is effective in reducing posterior dural adhesions in the spine with no apparent safety issues. It can improve patients' postoperative clinical outcome.

Review Case ReportsPost-traumatic pseudoaneurysm of the medial plantar artery combined with tarsal tunnel syndrome: two case reports.
Pseudoaneurysms in the foot are more often reported in the lateral plantar artery than the medial plantar artery, most likely because of its more superficial location. There are no reports of pseudoaneurysm of the medial plantar artery after trauma. We present two cases of pseudoaneurysm of the medial plantar artery after blunt foot trauma and foot laceration. ⋯ The patients were treated successfully using transcatheter embolization without the need for surgical intervention. The tarsal tunnel syndrome also subsided. Here, the authors report these cases and provide a review of literature.

Randomized Controlled Trial Comparative StudyMini-midvastus versus mini-medial parapatellar approach in total knee arthroplasty: a prospective, randomized study.
To date, no English literature has evaluated the short-term results of the mini-medial parapatellar approach compared with the mini-midvastus approach. This prospective, randomized study was performed to compare the short-term results of total knee arthroplasty using either a mini-midvastus or a mini-medial parapatellar approach. ⋯ Based on these results, we believe that the early results are similar between mini-midvastus and mini-medial parapatellar approach, ultimately the selection of the surgical approach will depend on the surgeon's experience and preference.
