Postoperative lumbar plexus injury after lumbar retroperitoneal transpsoas minimally invasive lateral interbody fusion.

Study Design: Retrospective review.

Objective: To evaluate the motor and sensory deficit rate after the lumbar retroperitoneal transpsoas minimally invasive lateral interbody fusion (MIS LIF) by reviewing a single surgeon's experience.

Summary Of Background Data: The MIS LIF is an increasingly used alternative to traditional open anterior or posterior operations to treat a host of spinal disorders.

Subsidence of polyetheretherketone intervertebral cages in minimally invasive lateral retroperitoneal transpsoas lumbar interbody fusion.

Study Design: A retrospective review.

Objective: The objective is to evaluate subsidence related to minimally invasive lateral retroperitoneal lumbar interbody fusion by reviewing our experience with this procedure.

Summary Of Background Data: Polyetheretherketone intervertebral cages of different lengths, widths, and heights filled with various allograft types are commonly used as spacers in lumbar fusions.

Use of titanium expandable vertebral cages in cervical corpectomy.

We aimed to investigate the usefulness of titanium expandable cages for vertebral body reconstruction after anterior cervical corpectomy. The records of 29 patients treated with expandable titanium cages for a variety of indications were analysed retrospectively. There was evidence of fusion in all patients.

Polyethylene glycol (PEG) hydrogel dural sealant and collagen dural graft matrix in transsphenoidal pituitary surgery for prevention of postoperative cerebrospinal fluid leaks.

Cerebrospinal fluid (CSF) rhinorrhea is the most common complication after transsphenoidal pituitary surgery. The authors compare their previous experience using an autologous fat graft and lumbar drain placement in 107 patients with their current technique of using a dural sealant and collagen matrix in 97 patients to prevent postoperative CSF leak after pituitary tumor resection. The failure rate for CSF leak repairs between the two groups was similar.
