Total Elbow Arthroplasty in the Context of an Olecranon Nonunion: A Surgical Technique and Report of Three Cases.

The deficiency of the triceps tendon has been considered a relative contraindication to performing a total elbow arthroplasty. One of the conditions that may compromise triceps integrity is the presence of an olecranon non-union (ON). In this scenario, the placement of a total elbow arthroplasty in a patient with end-stage elbow arthritis is a complex problem to be solved.

Description of unusual osteochondral laminar fragment patterns in Distal Radius fractures.

Background: Distal radius fracture (DRF) is one of the most common fractures and, frequently, surgical treatment is mandatory in the presence of an intra-articular fracture. However, there are some unusual intra-articular fracture patterns, were it remains challenging to properly recognize and anatomically reconstruct the articular surface. The objective of the present study is to describe an intra-articular fracture pattern of the distal radius characterized by the presence of osteochondral laminar fragments, which could potentially require a different treatment to standard stabilization.

Time until union in absolute vs. relative stability MIPO plating in simple humeral shaft fractures.

Purpose: The objective of this study is to evaluate the effect of absolute stability (AS) versus relative stability (RS) performed through a minimally invasive plate osteosynthesis (MIPO) in AO/OTA 12A1 and 12A2 fractures on healing and the time to radiographic union.

Methods: This was a retrospective cohort study of all patients treated with plate fixation for AO/OTA type 12A1-A2 fractures at a single institution. Patients were grouped according to the type of stability used in their surgery.

Trapeziometacarpal osteoarthritis: Arthroscopic hemitrapeziectomy using the Thenar Portal.

Background: Although the standard 1Radial and 1Ulnar portals allow for visualisation of most of the trapezium articular surface, the proximity of these two portals can often make arthroscopic triangulation and visualisation of the most lateral capsule and joint surface challenging. Despite its already reported advantages in improving visualisation, there is little literature reporting the clinical experience with the Thenar Portal. The purpose of this study is to describe potential complications and the short-term clinical-radiographic outcomes of arthroscopic hemitrapeziectomy using the Thenar Portal in order to determine its safety and efficacy as a standard working portal.
