Femoral Allograft Reconstruction: Verifying the Fit Before the Graft Reaches the OR
Resecting a bone tumor is only half the job when reconstruction follows. This case shows how patient-specific guides for the resection and the allograft share the same cutting geometry, and how a digital check on the graft caught a poor fit before it ever reached the operating room.

Pelvic Tumor Near the Sciatic Notch: Fixing the Sacroiliac Joint Before It Moves
When a pelvic tumor invades the sacroiliac joint, the resection itself puts the joint's reconstruction at risk. This case shows how a patient-specific guide locks in the implant trajectories before the tumor is even removed, so the sacroiliac joint can be rebuilt exactly as planned.

Total Knee Arthroplasty: Where Personalization Really Happens
In total knee arthroplasty, personalization goes beyond implant selection: the varus/valgus angle of the distal resection and the femoral component's rotation are set to the patient before the surgeon enters the OR. That is where manufacturers differentiate — not only in implant geometry, but in the precision of the plan behind it. Here's how 3D-Side builds a planning platform shaped around your implant portfolio, from screen to manufacturing.

A Variable-Margin Scapula Resection: Clearing the Tumor While Preserving the Coracoid
A partial scapula resection close to the acromion and coracoid process raises a question beyond the tumor itself: how much margin can be taken without compromising the bone segments the shoulder still needs to function. This case used a variable margin, 5 mm along the coracoid side, 10 mm along the two inferior planes, and a cutting guide shaped as a hook around the acromion to guide the resection precisely.

Patient-Specific Guide for Corrective Osteotomy: Closing an Angle and a Rotation in One Move
A cubitus valgus deformity rarely comes down to a single angle. This case combined a 20° medial closing correction with a 12° derotation, using a patient-specific guide system built around four K-wires that align only once both corrections are achieved together — closing an angle and a rotation in one motion.

Periacetabular Chondrosarcoma: Why the First Resection Is the Only One That Counts
For grade 2 chondrosarcoma, the surgical margin is the only oncological defense — chemotherapy and radiation offer no safety net. In this periacetabular case spanning the acetabular and pubic regions, a single patient-specific guide was built in two connected parts to execute three cutting planes with a 10 mm margin in one pass.

Distal Tibia Tumor Resection: Two Guides Built as Geometric Counterparts
Discover how two patient-specific surgical guides were designed as geometric counterparts to achieve accurate distal tibia tumor resection and anatomical allograft reconstruction in a case led by Prof. François Sirveaux.

Femoral Neck Osteotomy: A Four-Guide System and What One of Them Taught Us
A femoral neck osteotomy performed by Dr. Wudbhav Sankar at Children's Hospital of Philadelphia, guided by four patient-specific instruments. Three deployed intraoperatively and one that couldn't be, revealing as much about 3D surgical planning as those that were.

Pelvic Tumor Resection: Why Two Patient-Specific Guides
The tumor combined a bony component with an overlying soft tissue mass. Whether that mass could be displaced enough to fit a single large guide beneath it could not be predicted with certainty. The answer: two distinct guides, one lateral, one posterior, connected by a chevron geometry anchored on the sciatic notch

Grade 2 Iliac Chondrosarcoma: Extra-Articular Resection and Reconstruction with Patient-Specific Instrumentation
Extra-articular resection of a grade 2 iliac chondrosarcoma via ilioinguinal approach, planned with two patient-specific guides: one for resection, one for Ice-cream cone reconstruction. A single 3D anatomical reconstruction covering both operative stages, from the first cutting plane to final implant positioning.
