Less invasive mini-open adult spinal deformity surgery

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Adult spinal deformities (ASD) present significant surgical challenges, particularly in achieving adequate spinal correction.
• Rigidity of the spine necessitates effective mobilization for optimal surgical outcomes, especially in the sagittal plane.
• Current minimally invasive surgery (MIS) approaches, including lateral methods, often struggle to adequately improve lordosis and sagittal balance in ASD patients.

Purpose of the Study:

• To illustrate a mini-open surgical technique for improving coronal and sagittal correction in adult spinal deformities.
• To demonstrate a method that avoids extensive exposure and soft tissue disruption associated with open surgery.
• To present a viable option for managing less severe spinal deformities (curves < 60°).

Main Methods:

• The study video demonstrates a multi-level transforaminal lumbar interbody fusion (TLIF) performed via a mini-open surgical approach.
• This technique aims to achieve spinal correction with reduced invasiveness compared to traditional open surgery.
• The procedure is specifically applied to adult spinal deformities with curves less than 60°.

Main Results:

• The illustrated technique allows for improvement in both coronal and sagittal spinal alignment.
• This mini-open approach results in minimal blood loss and a reasonable surgical timeframe.
• The method offers a less disruptive alternative to open surgery for specific ASD cases.

Conclusions:

• Multi-level TLIFs through a mini-open surgery represent a promising technique for managing adult spinal deformities (< 60°).
• This approach may reduce the significant morbidity associated with surgical correction of ASD.
• Further validation through larger studies and refinement of surgical methods are warranted to confirm feasibility and efficacy.
