Comparative Study
Extra-articular distal tibia facture (AO-43A): A retrospective study comparing modified MIPPO with IMN.
We introduce a new MIPPO procedure which is simple and effective for the treatment of extra-articular distal tibia facture (AO-43A). The aim of this retrospective study was to compare our modified MIPPO with IMN. ⋯ Our results have shown that our modified MIPPO has enormous advantages over IMN for extra-articular distal tibia fracture (AO-43A).

We describe the step-by-step process of a corrective osteotomy using 3D printed patient specific guides. Before surgery, bilateral computed tomography (CT) scans are made to plan correction in the affected limb. The digital pre-planning defines the location of the K-wires, drill holes, and the osteotomy site(s). ⋯ In the latter case, the previously drilled K-wires are used to adequately position the reduction guide. Fixation of the bone fragments using plating osteosynthesis finalizes the process. Although this technique has its specific limitations, it might serve as a powerful tool in the treatment of malunion of both articular and nonarticular fractures of the limb.

Osteoporosis is characterised by poor bone quality arising from alterations to trabecular bone. However, recent studies have also described an important role of alterations to cortical bone in the physiopathology of osteoporosis. Although dual-energy X-ray absorptiometry (DXA) is a valid method to assess bone mineral density (BMD), real bone fragility in the presence of comorbidities cannot be evaluated with this method. The aim of this study was to evaluate if cortical thickness could be a good parameter to detect bone fragility in patients with hip fracture, independent of BMD. ⋯ Cortical thinning measured from X-Ray of the femur identifies 21% additional fracture cases over that identified by a T-score <-2.5 (57%). FCI could be a useful tool to evaluate bone fragility and to predict fracture risk even in patients with normal and osteopenic BMD.

The refractory post-operative diaphyseal femur fracture (DFF) non-union is extremely difficult to treat and remains severe challenges for orthopedists. Although several traditional internal fixations and novel biomedical techniques have been used in managing this complication, its treatment is still fraught with severe challenges. ⋯ The cFALP is a promising surgical modality for DFF non-union treatment. However, because fibular harvest may cause severe complications, the cFLAP should only be considered in refractory DFF non-union cases.
