Neurological complications using a novel retractor system for direct lateral minimally invasive lumbar interbody fusion. | LitMetric

AI Article Synopsis

  • The study evaluated the use of the RAVINE retractor for minimally invasive lateral lumbar interbody fusion (MI-LLIF) in 140 patients with degenerative spinal conditions between 2011 and 2015.
  • Out of 228 treated spinal levels, the L4/5 level was the most instrumented, with 12 patients experiencing postoperative neurological complications, including transient thigh symptoms and five cases of femoral nerve palsy.
  • The results suggest that MI-LLIF using the RAVINE retractor is a safe and effective procedure, with most nerve-related complications resolving quickly, and recommend careful access to the L4/5 level.

Article Abstract

We describe our experience using the RAVINE retractor (K2M, Leesburg, VA, USA) to gain access to the lateral aspect of the lumbar spine through a retroperitoneal approach. Postoperative neurological adverse events, utilising the mentioned retractor system, were recorded and analysed. We included 140 patients who underwent minimally invasive lateral lumbar interbody fusion (MI-LLIF) for degenerative spinal conditions between 2011 and 2015 at two major spinal centres. A total of 228 levels were treated, 35% one level, 40% two level, 20% three level and 5% 4 level surgeries. The L4/5 level was instrumented in 28% of cases. 12/140 patients had postoperative neurological complications. Immediately after surgery, 5% of patients (7/140) had transient symptoms in the thigh ranging from sensory loss, pain and paraesthesia, all of which recovered within 12weeks following surgery. There were five cases of femoral nerve palsy (3.6% - two ipsilateral and three contralateral), all of which recovered completely with no residual sensory or motor deficit within 6months. MI-LLIF done with help of the described retractor system has proved a safe and efficient way to achieve interbody fusion with minimal complications, mainly nerve related, that recovered quickly. Judicious use of the technique to access the L4/5 level is advised.
