REVIEW
Naoki Nakano, Grace Yip, Vikas Khanduja
PURPOSE: Extra-articular hip impingement syndromes encompass a group of conditions that have previously been an unrecognised source of pain in the hip and on occasion been associated with intra-articular hip impingement as well. As arthroscopic techniques for the hip continue to evolve, the importance of these conditions has been recognised recently and now form an important part of the differential of an individual presenting with hip pain. The aim of this article, therefore, is to provide the reader with an evidence-based and comprehensive update of these syndromes...

PURPOSE: Significant post-operative pain occurs after hip arthroplasty. In a prior study, lumbar plexus nerve blocks provided comparable analgaesia to lumbar epidurals; however, multimodal analgaesics were not used consistently. METHODS: This study assessed a randomly selected cohort of 48 patients undergoing primary hip arthroplasty who received a regional anaesthesia technique for post-operative pain. Twenty-four patients with lumbar epidurals and 24 with single-injection lumbar plexus nerve blocks were reviewed using electronic medical records...

INTRODUCTION: The damage control orthopedics (DCO) concept is a sequential surgical management strategy indicated when ideal primary treatment is not possible or suitable. DCO principles are routinely applied to hand traumas in wartime practice, but could also be useful in a civilian setting when immediate specialized management cannot be carried out. METHODS: The authors report three typical observations of soldiers treated for a complex hand trauma on the field by orthopedic surgeons from the French Military Health Service (FMHS)...
