Cleidocranial dysplasia (CCD) is an autosomal dominant inheritable skeletal disorder characterized by cranial dysplasia, clavicle hypoplasia and dental abnormalities. This disease is mainly caused by heterozygous mutations in RUNX2, a gene that encodes an osteoblast-specific transcription factor. In the present study, mutational analyses of RUNX2 gene were performed on four unrelated Chinese patients with CCD. Four different RUNX2 mutations were detected in these patients, including one nonsense mutation (c...

BACKGROUND: The coracoid approach is recognized as the simplest approach to perform brachial plexus anaesthesia, but needle visualization needs to be improved. With a different needle entry point, the retroclavicular approach confers a perpendicular angle between the ultrasound and the needle, which theoretically enhances needle visualization. This trial compares these two techniques. The leading hypothesis is that the retroclavicular approach is comparable to the infraclavicular coracoid approach in general aspects, but needle visualization is better with this novel approach...

Clavicle fracture reported incidence is about 5% of fractures in adult; among them, those located in the middle third of the shaft represent more than 80% from the total of cases. Due to the special morphological and biomechanical constraints of the clavicle, several methods for restoring morphological integrity in these fractures are described, including conservative, non-surgical treatment. The last 10 years of clinical studies in the field have favored the surgical treatment for selected cases; several osteosynthesis implants are in use - mostly anatomical plates with specific advantages and documented complications...

BACKGROUND: Most midshaft clavicle fractures affect the economically active population, which is negatively impacted by transient limb impairment during the treatment. There is still debate about the advantages and disadvantages of surgical treatment for these fractures. METHODS: In this prospective randomized controlled trial, 117 patients were allocated to 1 of 2 groups: nonsurgical treatment with a figure-of-eight harness or surgical treatment with anteroinferior plate osteosynthesis...

This study compares the use of 0.05 and 0.10 alpha levels with the updated osteometric pair-matching model on two samples of the os coxa, scapula, and clavicle. The samples include the Forensic Data Bank, and the osteometric sorting reference used within the Defense POW/MIA Accounting Agency. Mixed-effects two-way analyses of variance were used to analyze bilateral asymmetry in the standard measurements. In total, 3,793,566 t-tests were conducted for osteometric pair-matching analysis. The results indicate high levels of exclusion power, and accuracy can be obtained with the os coxa and scapula...

Tuberculosis (TB) is a chronic disease that may affect any part of the human body. Though the osteoarticular TB is not uncommonly seen, TB of the sternoclavicular joint (SC joint) is an infrequently reported condition. The very fact that many physicians have never seen a single case of SC joint TB in their entire career makes them never think of this condition in cases of chronic swellings of the medial end of clavicle. We are reporting here our experience with nine cases of SC joint TB that were treated by us...

Acromioclavicular (AC) joint separation is a common injury seen in the young adult athletic population. Both the indications for surgical management and the best operative technique remain controversial. One of the most popular reconstruction techniques is the anatomic double-tunnel coracoclavicular (CC) ligament reconstruction. However, there have been several case reports of clavicle fractures with this technique. This article presents a single-tunnel reconstruction technique that aims to restore both the CC and AC ligament function, while minimizing fracture risk...

Injuries to the acromioclavicular (AC) joint are becoming common with contact sports and bike accidents. It is well known that in AC dislocations, the first structure to fail is the AC capsule followed by the trapezoid and conoid ligaments. The function of these ligaments must be restored to restore the anatomy and physiology of the AC joint to get the best results. Until now, no technique has emerged as the gold standard for restoration of the AC joint anatomy and function. In our technique, the stress is on recreating the anatomy to make it more individualized based on individual variations...

BACKGROUND: There are several options for reconstruction of proximal humerus resections after wide resection for malignant tumors in children. The clavicula pro humero technique is a biologic option that has been used in the past, but there are only scant case reports and small series that comment on the results of the procedure. Because the longevity of children mandates a reconstruction with potential longevity not likely to be achieved by other techniques, the clavicula pro humero technique may be a potential option in selected patients...

Clavicle fractures are among the most common fractures occurring in the general population, and the vast majority are localized in the midshaft portion of the bone. Management of midshaft clavicle fractures remains controversial. Although many can be managed nonoperatively, certain patient populations and fracture patterns, such as completely displaced and shortened fractures, are at risk of less optimal outcomes with nonoperative management; surgical intervention should be considered in such cases. The purpose of this article is to demonstrate our technique of midshaft clavicle fixation using minimally invasive intramedullary fixation...
