The impact of the AO Foundation on fracture care: An evaluation of 60 years AO Foundation.
Sixty years ago, the Association of Osteosynthesis (AO) was founded with the aim to improve fracture treatment and has since grown into one of the largest medical associations worldwide. Aim of this study was to evaluate AO's impact on science, education, patient care and the MedTech business. ⋯ AO's impact on science, education, patient care, and the MedTech business was significant because AO addressed hitherto unmet needs by combining activities that mutually enriched and reinforced each other.

Comparative Study
Comparison of risk factors for postoperative complications across age groups in patients undergoing ORIF of the ankle.
Risk factors associated with various adverse outcomes for patients undergoing open reduction and internal fixation (ORIF) of the ankle, and how these risks differ between younger and older patient populations, has not been clearly established. Objective quantitative data may aid physicians in surgical decision making, individualizing postoperative management, and targeting interventions for reducing postoperative comorbidity. The purpose of this study is to compare the incidence of and risk factors for adverse postoperative outcomes following ORIF of ankle fractures across patient age groups. ⋯ Patients undergoing ORIF of the ankle should be well-informed of the potential risks of surgery as they pertain to specific comorbidities. Multidisciplinary approaches are warranted for appropriate management of patients with multiple comorbidities.

Unstable pelvic fractures frequently require emergency stabilization using a C-clamp or external (CC/EF) fixation. However, the effectiveness of this intervention and associated complications are still a matter of debate. ⋯ Primary stabilization of unstable pelvic fractures with C-clamp or external fixation is associated with a decreased mortality and was not an independent risk factor for complications after secondary surgery. However, the risk for infection after ilio-sacral screw fixation increased almost 5-fold after C-clamp use.

Volar locking plate (VLP) fixation has become the gold-standard treatment for distal radius fractures (DRFs). Especially, internal fixation of the volar lunate facet fragment is essential for the treatment of AO C3-type DRFs. On the other hand, the necessity of the fixation of the dorsal lunate facet fragment (dorsoulnar fragment) remains unclear. The purpose of the present study was to measure three-dimensionally the size of the dorsoulnar fragments in AO C3-type DRFs using computed tomography (CT) images in detail, and to reveal relationships of the size and stabilization of the dorsoulnar fragment with postoperative fracture displacement after VLP fixation. ⋯ Stabilization of the dorsoulnar fragment with at least one screw of the volar locking plate was necessary to prevent postoperative fracture displacement regardless of dorsoulnar fragment size in AO C3-type distal radius fractures.

Reconstruction of a bone defect using the Masquelet induced membrane technique has been well described. However, there are few reports of arthrodesis using this technique. In this case report, we describe a modified Masquelet technique for ankle arthrodesis with nailing. ⋯ At 1 year postoperatively, firm bony union was achieved and the implant was removed. At follow-up 3 years after his injury, the patient is able to walk, undertake physical work, and has no clinical signs of infection. Our experience suggests that a modified induced membrane technique may be useful when treating an open limb fracture with an extensive osteochondral defect where preservation of the joint is difficult and arthrodesis is considered.
