  • Pre-operative planning versus post-operative CT scans of the position of the hip rotation center

    Pre‐operative planning versus post-operative CT scans of the position of the hip rotation center

    The central point of the implant model was defined as the hip rotation center and identified in a coronal view by measuring vertical and horizontal distances in an X–Y coordinate system starting from the reference point. The positions according to (a) pre-operative planning and (b) post-operative CT scans were compared in order to determine the accuracy of preoperative planning.

    Schematic diagram of intramedullary fixation of a clavicular fracture with a cannulated screw.(a) The guiding device has been pushed into the medullary cavity of the distal fractured end, then the guide pin inserted and pushed out posterior to the acromion.(b) The fractured bone has been set, then the guide pin pushed back into medullary cavity of the proximal fractured end and the cannulated screw screwed in along the guide pin after tapping.(c) The clavicular fracture is fixed.

  • ALIF implant

    ALIF implant

    (A) ALIF interbody device with integral fixation. (B) ALIF implant with anterior plate fixation. (C) ALIF implant with posterior instrumentation.

  • The process of the rotational acetabular osteotomy

    The process of the rotational acetabular osteotomy

    (a) Rotational acetabular osteotomy was performed by a curved osteotome. (b) The acetabular bone block was displaced laterally and anteriorly by rotation and fixed with long cortical screws.

  • Schematic diagram of operating procedure

    Schematic diagram of operating procedure

    (A) A longitudinal dissection was made following the medial border of the patella to dissect the vastus medialis and medial retinaculum, and then a transverse dissection was made along the junction of the vastus medialis and medial retinaculum to the medial femoral condyle with the aim of dividing both of them. (B) The vastus medialis and medial retinaculum were divided. (C) The medial retinaculum was pulled proximally and laterally to near the upper pole of the patella with fixation. (D) The vastus medialis was pulled distally and laterally to near the middle line of the patella with fixation, then the two overlapping tissues were sutured together.

  • MLST screw

    MLST screw

    Model showing the axial trajectory for the MLST screw (arrow). The screw follows a medial to lateral path, thus avoiding lateral dissection of the paraspinal musculature.

    Workflow with 50/50 technique

    Workflow with 50/50 technique: Midline incision and PLIF are performed and a pedicle screw inserted into the caudal pedicle. Insertion of a percutaneous screw into the cranial pedicle avoids damage to the cranial/mobile facet joint.
