The study concerns a retrospective analysis of all subjects operated as of 1st Jan 2008 using Minimal Access Surgical Technique (MAST). The study is descriptive in nature and will present the observation of all cumulated patients operated with MAST.
The study data will include the general health information of the subjects prior to surgery, information on the surgery such as OP time, blood loss, and the postoperative wound healing process (until discharge), which is on average the 10th postoperative day.

BMI < 25
Body Mass Index (WHO) established by WHO. BMI < 25 has been defined as 'normal weight'.
25 >= BMI < 30
Body Mass Index (WHO) established by WHO. BMI >= 25 and < 30 has been defined as 'overweight'.
BMI >= 30
Body Mass Index (WHO) established by WHO. BMI > 30 has been defined as 'obese'.
- Postoperative Complications in the BMI Groups During Post Operative Hospitalization. [ Time Frame: at hospital discharge ]Postoperative complications related to the operation within the body mass index groups. A complication is any harmful event occuring during the surgery until hospital discharge.
- Operation Duration [ Time Frame: after surgery ]Duration of the operation in minutes.
- Blood Loss [ Time Frame: after surgery ]Loss of blood during surgical procedure in milliliters.
- Number of Spine Segments [ Time Frame: peri operative ]Number of affected spine segments. One spine segment is defined as 2 vertebral bodies and the intervertebral disc (between the 2 vertebral bodies). For this study the number fo affected spine segments is identical to the number of operated intervertebral discs.
- Drainage [ Time Frame: at hospital discharge ]Drainage during hospitalization. The drainage was placed during the surgery and has been removed prior to hospital discharge. The amount of drainage in milliliters has been measured.
- Days of Hospitalization [ Time Frame: at hospital discharge ]Total time of hospitalization.
