The TASER(®) is a self-defense weapon whose use has now become commonplace among law enforcement agencies. Electronic control weapons were first used in the USA in the 1990s and then adopted in Europe and France. We report a case of an 18-year-old male who presented a penetrating lesion of the middle phalanx of the left index finger. To the best of our knowledge, this is the first complex finger injury due to the TASER(®). It highlights the potential major risks to finger vitality and function with use of this electrical weapon., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Carpal coronal fractures are rare. We report the case of a 15 year-old male who fell from a balcony and suffered a displaced coronal fracture of the capitate, hamate and triquetrum. The diagnosis, which was initially made based on the X-rays, was confirmed by CT scan. Open reduction and internal fixation using Herbert screws was performed. To the best of our knowledge, this is the first published case of a coronal fracture of these three bones. The patient returned to normal activities after six months., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Axillary nerve injuries still go undiagnosed far too often despite their frequency. However the quality of the outcome depends on expert management and prompt surgery. To optimise the latter, we re-examined 83 operated cases of traumatic lesions of the axillary nerve. We analysed the neurological and functional recovery of these patients by means of a follow-up evaluation at 6 years postop. The results were classified by age, mechanism of injury, delay to surgery and the presence or otherwise of associated neurological or osteo-articular lesions. We highlighted that a high index of suspicion ought to exist in all cases of trauma to the shoulder in a patient aged more than 40, any injury associated with palsy of the long head of triceps and in the case of an osteo-articular lesion due to high-velocity trauma. A complete lack of shoulder abduction must always prompt a search for a lesion of the axillary nerve as well as a suprascapular nerve palsy or rotator cuff lesion. There are few literature reports of surgical management of this particular nerve injury. An early MRI scan as part of the management should improve results by a reduction in the delay before surgery. As a result of our investigation we conclude that a lesion of the axillary nerve without signs of recovery at 3 months should be referred to a centre specialized in peripheral nerve surgery.

Introduction: The aim of this study was to assess the results of a prospective study of 138 cases with carpal tunnel syndrome operated on by a percutaneous technique., Method: One hundred and twenty-nine patients (108 women and 21 men, with a mean age of 49.9 years) underwent preoperative assessment via a questionnaire and a clinical examination (the Weber test, buckle test, Kapandji test, Tinel test, Phalen test, Vainio test and grip force assessment). The surgical technique was singularised by the insertion of a probe cannula in the carpal tunnel so that the blade could be guided during annular ligament section., Results: The results were assessed at one, three and six months follow-up: 98.5% very good and good results were obtained (Kelly criteria); two patients presented with an algodystrophic syndrome. No vascular, tendinous or neurological complications were noted, and the procedure was in no instance switched to an open technique., Discussion: The main advantages of this technique are a rapid recuperation of hand function, with an average of 22.6 days off work, a low complication rate, and simple equipment.
