Unstable lesions of the forearm: Terminology, evaluative score and synoptic table.

The term "unstable lesions of the forearm" (ULF) was born to more easily describe how a partial or complete instability of the forearm unit might occur due to a traumatic loss of the transverse or longitudinal connection between the radius and ulna. For such an alteration to occur, at least two of the three main osteoligamentous locks (proximal, middle and distal) must be interrupted, often in association with a radial and/or ulnar fracture. Examining the historical patterns (Monteggia, Galeazzi, Essex-Lopresti and criss-cross lesions) and variants described in the literature, out of a total of 586 recorded interventions for forearm trauma, two elbow teams and one wrist team selected 75 cases of ULF.

Choice of treatments of the coronal shear fractures of the humerus. A national survey of Italian AO members.

Introduction: Coronal shear fractures of the distal humerus are uncommon injuries representing 6% of distal humeral fractures. There is no univocal consensus about the correct management of this type of fracture. A national survey was conducted to gain more insight into the current classification, diagnosis and treatment of coronal shear fractures in Italy.

Computer-Aided Planning and 3D-Printed Surgical Guide in Patients with Extreme Cubitus Varus Deformity: A Report of 2 Cases.

Case: We describe 2 patients with extreme triplanar cubitus varus deformity, treated with step-cut corrective virtually planned osteotomies and performed with custom-made surgical guides. The surgery was simulated on the patients' bone 3D-printed model to verify the effectiveness of the surgical plans. At a medium 21-month follow-up after surgery, in both patients, clinical and radiological results were fully satisfactory, and no complications have been reported.

Open Reduction and Internal Fixation Using Double Plating with Biological and Artificial Bone Grafting of Aseptic Non-unions of the Distal Humerus: Clinical Results.

Aim: Intra-articular non-union of fractures is an uncommon but complex problem because in general, it is characterised by marked instability, pain, strength loss and significant functional limitation. The aim of this study is to report our prospective medium-term outcomes of the treatment of intra-articular, distal humeral aseptic non-unions using open reduction and internal fixation, augmented with artificial bone.

Materials And Methods: A retrospective case series of 16 patients with intra-articular, aseptic non-unions of the distal humerus was analysed for range of motion, pain, Mayo Elbow Performance Scores (MEPS) and Oxford Elbow Scores (OES) after 12 months.

Elbow hemiarthroplasty for acute distal humeral fractures and their sequelae: medium- and long-term follow-up of 41 cases.

Background: The earliest distal humeral hemiarthroplasty (or elbow hemiarthroplasty [EHA]) implants, which date back to the late 1940s, were performed in patients with severe elbow joint injuries as an alternative to arthrodesis. After some clinical reports and case studies with a short follow-up, published in the 1990s, a new "anatomically convertible" EHA model was introduced in 2005 and became a common surgical option to treat complex elbow fractures and their sequelae. We describe the mid- and long-term outcomes of EHA performed to treat acute intra-articular fractures or their sequelae.
