Minimal Access Surgical Technique (MAST) in Obese Patients in Degenerative Lumbar Disease
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.

- Postoperative Complications in the BMI Groups During Post Operative Hospitalization. [ Time Frame: at hospital discharge ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]Duration of the operation in minutes.
- Blood Loss [ Time Frame: after surgery ] [ Designated as safety issue: No ]Loss of blood during surgical procedure in milliliters.
- Number of Spine Segments [ Time Frame: peri operative ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]Total time of hospitalization.
