"Internal fixation of proximal humeral fractures using the Polarus intramedullary nail: our institutional experience and review of the literature".

Background: The purpose of this study is to evaluate the functional outcome, union and complication rates after surgical treatment of unstable or displaced proximal humeral fractures using the Polarus intramedullary nail, by reviewing our institutional experience and the relevant current literature.

Methods: Twenty-seven patients were treated operatively for proximal humeral fracture using the Polarus nail. Fractures were classified according to Neer's classification.

The role of reduction and internal fixation of Lisfranc fracture-dislocations: a systematic review of the literature.

A systematic review of the literature was performed in order to evaluate the role of reduction and internal fixation in the management of Lisfranc joint fracture-dislocations. Articles were extracted from the Pubmed database and the retrieved reports were included in the study only if pre-specified eligibility criteria were fulfilled. Eleven articles were eligible for the final analysis, reporting data for the management of 257 patients.

Investigation on the distal screw of a trochanteric intramedullary implant (Fi-nail) using a simplified finite element model.

Numerous studies have been published concerning the characteristics and the behaviour of the intramedullary devices in the treatment of the intertrochanteric hip fractures. However, there is still room for further exploration and exploitation concerning the implant behaviour with respect to the parts of the implant assembly (nail, lag screw and distal screw). Towards this direction, the present paper aimed at revealing the effect of the position of the distal screw on the mechanical behaviour of the fixation device.

Recurrent intra-articular osteoid osteoma of the hip after radiofrequency ablation: a case report and review of the literature.

We present a case of a 53-year-old woman with recurrent intra-articular osteoid osteoma of the hip 6 months after initial treatment with percutaneous radiofrequency ablation. En bloc surgical excision of the osteoid osteoma and prophylactic internal fixation for impending stress fracture was performed. The patient is pain free, has returned to normal function and there is no sign of recurrence at the one-year follow-up.

Osteoid osteoma of a metacarpal bone: a case report and review of the literature.

Introduction: Osteoid osteoma is a benign tumor of the growing skeleton. It presents with pain, which is usually worse at night. The radiographic features consist of a central oval or round nidus surrounded first by a radiolucent area followed by another area of sclerotic bone.
