Clavicle non-union is a challenging problem. Open reduction with internal fixation and autologous bone grafting is usually the first line treatment. In case of failure, the medial femoral condyle corticoperiosteal flap in association with a non-vascularized bone graft is one of the therapeutic options, which is well adapted to the clavicle anatomical characteristics.

Clavicular fractures are some of the most common bone injuries in the paediatric population, yet the rates of nonunion are very low under 18 years. To the best of our knowledge, posttraumatic nonunion of the clavicle in a paediatric population is rarely reported. We report the case of an 11-year-old girl who presented with a nondislocated fracture of the midshaft to the proximal third of the right clavicle. Read More

Unfallchirurgische Klinik, Medizinische Hochschule Hannover, Hannover, Deutschland.

Background: The shoulder girdle is a chain of bones and joints which connect the upper extremity to the axial skeleton. The shoulder as a biomechanical unit has a remarkable range of motion and is therefore frequently prone to injuries of the three major joints (sternoclavicular joint, acromioclavicular joint, glenohumeral joint) and the bony elements (clavicle, scapula, humerus). Projection radiography is still the first imaging modality for injuries of the shoulder and usually sufficient for initial diagnosis and injury classification. Read More

Addenbrooke's Hospital, Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

Acromioclavicular joint injuries are common and account for up to 12% of all shoulder girdle injuries and have been reported as being as high as 50% in sports-related shoulder injuries. While the majority of acromioclavicular joint dislocations can be treated non-operatively, there are certain injury configurations, which can include high-grade dislocations in overhead athletes, where surgery may be indicated. The surgical management of acromioclavicular joint instability has moved towards recreating the action of the coracoclavicular ligaments by resuspending the clavicle on to the coracoid. Read More

Background: Innervation of the clavicle is complex and debated, with scarce data on the analgesic and clinical impact of regional anaesthesia after surgical repair of clavicle fracture.

Methods: In order to assess the analgesic efficiency of an interscalene brachial plexus block (ISB) for surgical repair of clavicle fracture, 50 consecutive patients scheduled for surgical fixation of middle/lateral clavicle fracture under general anaesthesia with ISB were prospectively enrolled. This cohort was compared to a historical control of 76 retrospective patients without regional block. Read More

Purpose: The clavicle hook plate has been commonly used to treat distal clavicle fractures and acromioclavicular (AC) joint dislocations; however, midshaft clavicle fracture at the medial end of the hook plate remains an underestimated complication. We aimed to discover the risk factors for this complication and the influence of these risk factors on patients and to suggest preventive surgical techniques.

Methods: We retrospectively reviewed the records of 150 patients with acute distal clavicle fractures or acute AC joint dislocations treated by internal fixation with a clavicle hook plate. Read More

Historically, extra-articular scapular body fractures were treated nonsurgically, but displaced fractures of the glenoid neck can lead to dysfunction. Controversy exists regarding which extra-articular scapular fractures should be treated surgically; however, nonsurgical management of severely displaced scapular body fractures can result in satisfactory outcomes. Inclusion criteria for this study were medial or lateral displacement greater than 2 cm, angular deformity between fracture fragments greater than 45°, or glenopolar angle less than 22°. Read More

Diaphyseal fractures of the clavicle had until recently the reputation to always heal with abundant callus formation, except if operated, due to a reported high rate of nonunion after plate fixation by older series. The reason would be that the bone has only periosteal vascularization, easily destroyed by periosteal stripping for implant apposition. Bone autograft and external fixation has been reported as the best technique to heal a nonunited clavicle nonunion. Read More
