Biomechanical analysis of cadaveric wrists before and after MOTEC wrist arthroplasty using a hexapod robot.

This study compares wrist motion, biomechanical behaviour and radiographic parameters before and after total wrist arthroplasty using a fourth-generation spherical articulation prosthesis. A total of 10 cadaveric specimens were assessed using a hexapod Stewart platform robot. After arthroplasty, there were significant increases in both stiffness and phase angle of wrist motion across all planes of motion assessed.

Tibiotalocalcaneal nail and primary closure for the management of open ankle fractures in the elderly patient; results from a major trauma centre.

Introduction: Open ankle fractures in elderly patients are challenging injuries to manage. The aim of this study was to assess the outcome of elderly patients with open ankle fractures treated with a tibiotalocalcaneal nail and primary wound closure.

Methods: We identified all open ankle fractures in patients over 65 referred to our major trauma centre managed with a tibiotalocalcaneal nail and primary wound closure over 10 years.

Transradial Transcapitate Perilunotriquetral Coalition Fracture Dislocation.

Perilunate fracture dislocations (PLFDs) are uncommon, usually resulting from high-energy trauma. Several classification systems describe the patterns of injury seen, but there is still significant variation and patterns of injury that do not fit within these classifications continue to be described. Carpal coalitions are rare, mostly asymptomatic, and are, as a result, usually identified incidentally.

Hemiarthroplasty versus open reduction internal fixation for intra-articular distal humerus fractures in older patients.

Background: Intra-articular distal humerus fractures in the older population remain a challenge to fix, due to the comminution of fragments and poor bone stock. Recently Elbow Hemiarthroplasty (EHA) has gained popularity to treat these fractures, however no studies exist comparing EHA to Open Reduction Internal Fixation (ORIF).

Objectives: To compare the clinical outcomes of patients over the age of 60 years treated with ORIF or EHA for multi-fragmentary distal humerus fractures.

Strain reduction screws for nonunions following fixation around the elbow - A case series and review of the literature.

Background: Nonunions following fracture fixation result in significant patient morbidity and financial burden. Traditional operative management around the elbow consists of removal of metalwork, debridement of the nonunion and re-fixation with compression, often with bone grafting. Recently, some authors in the lower limb literature have described a minimally invasive technique used for select nonunions where simply placing screws across the nonunion facilitates healing by reducing inter-fragmentary strain.
