Abstract

Implantable devices for fixation of curved bones such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state using a shape locking section. The implantable devices further include a main body and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

Description

Background technique

[0001] The following descriptions are provided to aid the reader in understanding. None of the information presented or references cited is admitted to be prior art.

[0002] Fractures can occur in straight bones such as the femur or in curved bones such as the pelvic bone. Repairing a fracture usually involves two steps: fracture reduction and fracture fixation. Reduction is the step of reducing the fracture by minimizing the distance between the bone fragments and anatomically aligning the bone to minimize deformity after healing. Both surgical and non-surgical reduction methods exist. Immobilization, the step of keeping fracture fragments mechanically stable and close together to promote bone healing, can take weeks or longer, depending on the type of fracture, bone type, and general health of the patient suffering the injury.
