Lumbar disc herniations may result in lower limb weakness. In such cases, there is a strong indication for surgical intervention through microdiscectomy. This clinical study aims to investigate preoperative factors that may influence the postoperative outcomes of patients undergoing this procedure.
Patients suffering from lower limb paresis (motor deficit) caused by lumbar disk herniation undergoing a single-level microdiskectomy
Age (years) > 17
Age (years) < 18
Medical history of lumbar spine surgery
Absence of limb paresis
Motor deficit caused by other than disk herniation aetiologies
Patients visiting the three recruitment hospitals, all located in North Greece.
Cohort
Prospective
Not listed
Muscle Strength
The strength of lower main muscles will be assessed and will be rated according to the Medical Research Council Scale for Muscle Strength. The scale takes values between 0 and 5, with 5 being the best possible (healthy).
Duration of paresis before surgical treatment
Time between the initiation of paresis and surgical treatment measured in days
Age
The age of participant as measured in years
Obesity
Body Mass Index (BMI) measured as the ratio between the mass measured in kilograms over the square of height measured in meters. There will be two groups of patients: a) with obesity and b) without obesity.
Diabetes Melitus
Participant is diagnosed with diabetes melitus (yes/no)
Hernia location
Categorisation of hernia location based on Magnetic Resonance Imaging (MRI) to a) central, b) subarticular, c) foraminal, and d) extra-foraminal.
