A bone anchor for attaching a suture thread or ligament comprises a main body extending along a longitudinal axis and having a fork-shaped end portion. The end portion is provided with a first and a second fork arm each extending between a constrained end and a free end and spaced apart by an axial slit for receiving a suture thread. Said first and second fork arms have, at their constrained ends, a transverse notch defining two axial retention shoulders for the suture thread.

Various implementations include an alignment device for carrying out a periacetabular osteotomy operation on a patient that includes a patient-specific acetabular unit, to be fixed in a univocal position on the iliac bone, in proximity of the acetabulum; a patient-specific iliac unit, to be fixed in a univocal position on the iliac bone, in a lateral position with respect to the acetabular unit; and a patient-specific bridge, to be connected in a rigid and univocal manner to the acetabular unit and to the iliac unit. The acetabular unit and the iliac unit assume a first mutual position incompatible with the bridge. When osteotomy is carried out and the bridge is connected to the acetabular unit and the iliac unit, they assume a second position, different from the first position and corresponding to a bio-mechanically correct position of the acetabulum with respect to the remaining portion of the iliac bone.

A cutting guide for periacetabular osteotomy comprises at least a first main body having a longitudinal opening for the insertion of a cutting instrument, extending from a first end to a second end of the first main body and at least two positioning and fixing arms extending away from the first main body from opposite sides with respect to the longitudinal opening, in order to correctly position the first main body on a bone and fix it thereto through respective fastening members.

A cutting guide for periacetabular osteotomy comprises at least one first main body having a longitudinal opening for the insertion of a cutting instrument, extending from a first end to a second end of the first main body and at least two positioning and fixing arms extending away from the first main body from opposite sides with respect to the longitudinal opening, in order to correctly position the first main body on a bone and fix it thereto through respective fastening members.

Disclosed is a guide for a flexible bone drill, including: a first body provided internally with a through channel; a second, internally hollow body, into which said first body can be inserted; said second body being provided with a through hole suitable to be placed in fluidic connection with the internal through channel of said first body; and said second body and said first body sliding relative to one another to vary the relative position of the hole with respect to said through channel. Other aspects are described and claimed.
