The improved positioning device, for use in hip, pelvis or bariatric surgery, securely and safely supports a morbidly obese patient lying in the lateral decubitus position at one side of an operating table so the surgeon may stand close to the anterior side of the patient. The support device includes a double-ended bracket having a pair of oppositely positioned padded end portions secured to an angular bracket post adapted to securely mount to an operating table via a question mark-shaped bracket. The angular bracket arm vertically adjusts to support the patient on one side, with the padded end portions applied to bony prominences such as the symphysis pubis and the lower side anterior superior iliac spine. The support device is used in combination with a posterior pelvic support plate, and a pair of anterior-posterior chest support plates to retain the patient in a secure and stable manner during surgery.

In a method for determining the pelvic inlet plane of the pelvic bone, which is defined by the following three points of the pelvic bone:

point A: spina iliaca anterior superior left

point B: spina iliaca anterior superior right

point C: symphysis pubis,

by non-invasive determination of the position of one of the two points A or B and point C, in order to also be able to carry out this determination whenever point A or point B is not accessible, it is proposed that the position of the following points of the pelvic bone be additionally determined non-invasively:

point D: spina iliaca posterior superior left

point E: spina iliaca posterior superior right,

and that the position of the pelvic inlet plane be calculated from the position of the non-invasively determined points A or B, C, D and E.

Disclosed herein is a method of phalloplasty for girth enhancement. It comprises incising minimally the outer skin of a penis; separating the skin and the hypoderm from a part immediately above Buck's fascia and peeling off the skin and the hypoderm in a region ranging from a part proximal to a glans to prepubic junction; forming a mesh structure of multiple slits in a penile implant; and fixing the penile implant to the penis by suture. The formation of a mesh structure of multiple slits or the use of an implant in multiple pieces makes it possible to cope with complications, thereby significantly reducing complications. Also, the multiple slits or multiple pieces form spaces therebetween, which lead to an increase in flexibility between the implant tissues, thereby enjoying the advantages of minimizing discomfort upon erection and reducing the occurrence of penis curvature. The delicate irregularities of the penis may serve as a factor promoting sexual stimulation upon sexual intercourse. Also, upon carvenosal injection therapy for erectile dysfunction, drugs for inducing erections can be easily injected into the space between the multiple slits or multiple pieces.
