The aim of this study is to evaluate the clinical presentation and management strategies of seroma formation following posterior lumbar spine decompression.

Posterior lumbar spine decompression is a widely employed surgical approach to alleviate neural element compression due to degenerative spinal conditions such as spinal stenosis, spondylolisthesis, and disc herniation. While generally effective in reducing symptoms and improving quality of life, this procedure is not without risk.

Seroma formation, in particular, may follow posterior decompressive surgery or fusion and is thought to arise from the accumulation of lymphatic or serous fluid in the dead space created by tissue dissection.

Inclusion Criteria:

• Age ≥ 18 years.
• Both sexes.
• Patients undergoing elective posterior lumbar spine decompression.

Exclusion Criteria:

• History of previous lumbar spine surgery.
• Active spinal infection, trauma, or malignancy.
• Severe medical comorbidities that contraindicate surgery or influence wound healing (e.g., uncontrolled diabetes, immunosuppression, severe cardiovascular disease).
• Patients unfit for general anesthesia.

This retrospective study will be conducted on 50 adult patients undergoing posterior lumbar spine decompression surgery at Kafr Elsheikh University Hospitals. Approval from the Medical Sciences Ethics Committee of Kafr Elsheikh Faculty of Medicine will be taken. Written informed consent will be obtained from all participants before enrollment.

The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
