Method for implantation of an implant for pelvic ring fractures

A method for implantation of an implant in a body, the method comprising the following steps:

• selecting the implant, the implant comprising a pelvic implant configured to stabilize at least one pelvic ring fracture in a pelvic ring of the body, the pelvic implant including
• a nail for intra-ossary implantation, the nail having a first end, a second end, a nail length and a longitudinal axis along the nail length, the nail configured to be passed intra-ossarily through a tunnel pre-drilled through a sacrum or intra-ossarily inserted into the pre-drilled tunnel in the sacrum without the nail providing fixation of the pelvic ring fracture in a direction of the longitudinal axis of the nail;
• a fixing device to secure the second end of the nail in at least one of the sacrum and a first pelvic bone of the body;
• a first locking element for relative fixation of a second pelvic bone of the body with respect to the nail,
• wherein the first end of the nail has a first transverse duct to receive the first locking element,
• wherein the first locking element comprises an anchoring section configured to anchor the first locking element in the second pelvic bone, and a locking section that corresponds with the first transverse duct of the nail in such that the first locking element is lockable in an angular stable manner to the nail,
• drilling the tunnel through the sacrum of the body,
• at least one of passing the nail through the tunnel and inserting the nail into the tunnel,
• securing the second end of the nail in at least one of the sacrum and the first pelvic bone with the fixing device,
• applying an external compression force on the pelvic ring such that the pelvic ring is compressed at least along the longitudinal axis of the nail, and
• extending the first locking element through the first transverse duct at the first end of the nail,
• anchoring the first locking element to the second pelvic bone, and
• fixing the first locking element to the nail such that the nail is secured against twisting and displacement relative to the second pelvic bone.
