Calcaneal fractures are infrequent but, more often, serious. We report a series of 29 cases of calcaneal fractures surgically treated in the Orthopaedics and Traumatology in the University Hospital (CHU) Hassan II of Fez. This retrospective study aims to present the principles and to evaluate the results of surgical treatment for articular fractures of the calcaneus, in comparison with conservative treatment. Our study included 21 men and 8 women, the average age was 21-61 years. Etiology was dominated by road traffic accidents as wel as by falls from a high place...

BACKGROUND: Flexion and compression forces to the trunk can cause severe instability of the vertebral column and the anterior chest wall, mostly associated with an unstable fracture of the sternum. In combination, the worst case would be a complete disruption of the trunk. Some authors consider the sternum-rib-complex to be the fourth vertebral column. This study discusses the possibilities to treat instable trunk injuries with sternal fractures concomitant to vertebral spine fractures through anterior sternal plating employing a locked plate osteosynthesis in a low profile design instead of the use of bulky implants...

The management of displaced, intra-articular calcaneal fracture represents a surgical challenge to even an experienced orthopedic surgeon. Plate osteosynthesis using an extended lateral approach is complicated by soft tissue problems, while those treated by closed reduction and percutaneous pinning cannot address all the intra-articular fragments sufficiently. The objective of our study is to evaluate restoration of subtalar joint and long-term functional outcomes in intra-articular displaced calcaneal fractures treated with transverse subcondral screws through a small incision on lateral aspect of calcaneus and percutaneously placed axial screws through the calcaneal tuberosity...

A healthy 72-year-old man presented with retention problems concerning the dentures in his maxilla. On account of extreme resorption, placement of implants without prior bone augmentation was not an option. The proposal was to use autologous bone harvested from the iliac crest. After a healing period of 4 months, a cone beam computed tomography scan was made, following which the virtual implant planning of 6 implants was carried out. With the help of a template supported by osteosynthesis screws, which had already been inserted during the augmentation procedure, the plan was applied to the patient...

BACKGROUND: Zygoma fracture is of clinical importance because malar prominence plays an essential role in facial appearance. Traditionally, most maxillofacial surgeons perform osteosynthesis with titanium plates and screws for rigid fixation. However, this procedure has certain disadvantages that include the possibility of implant exposure, palpability or loosening of the screws, painful irritation, temperature sensitization, and radiographic artifacts. In this study, we compared the function and satisfaction outcome between Bonamates(®) bioabsorbable implant and Leibinger titanium implant...

Reconstruction of unstable syndesmotic injuries is not trivial, and there is no generally accepted treatment guidelines. Thus, there still remain considerable controversies regarding diagnosis, classification and treatment of syndesmotic injuries. Syndesmotic malreduction is the most common indication for early re-operation after ankle fracture surgery, and widening of the ankle mortise by only 1 mm decreases the contact area of the tibiotalar joint by 42%. Outcome of ankle fractures with syndesmosis injury is worse than without, even after surgical syndesmotic stabilization...

Minimally invasive percutaneous plate osteosynthesis was developed on the concept that preservation of the soft tissue envelope during surgical management of distal tibial fractures is of paramount importance. We report on our early experience using this technique over a 1-year period with 14 such injuries that were treated by a locking compression plate via minimally invasive surgery. The surgical reduction was excellent in most of the cases and all fractures healed uneventfully. One superficial infection and a wound slough were the only complications recorded...

BACKGROUND: Comminuted fracture of the lower patellar pole has characteristics of both patellar fracture and avulsion of the patellar tendon. Therefore, components of both injury types should be considered during treatment. None of the traditional techniques has proven sufficient alone. Currently described is technique that incorporates principles of osteosynthesis as well as repair of the patellar tendon. METHODS: Total of 23 patients with comminuted fracture of the lower patellar pole were treated surgically and prospectively followed for 24 months...

Enhancing health research capacity in developing countries is a global health priority. Understanding the orthopedic burden of disease in Latin America will require close partnership between more-developed and less-developed countries. To this end, the Osteosynthesis and Trauma Care Foundation assembled a research consortium of Latin-American orthopedic leaders. Prior to the meeting, we surveyed attendees on perceived barriers to conducting research at their institutions. During the event, working groups discussed these barriers, developed strategies for addressing them, and planned future steps for collaboration...

Magnesium alloys are candidates for resorbable material in bone fixation. However, the degradation and performance of osteosynthesis plate/screw systems in vivo, under cyclic deformation, is unknown. We evaluated the outcomes of human standard-sized magnesium plate/screw systems with or without plasma-electrolytic surface modifications in a miniature pig rib model. Of a total of 14 minipigs, six were implanted with coated magnesium WE43 six-hole plates/screws, six received magnesium uncoated plates/screws, and two received titanium osteosynthesis systems...

Rat models are widely used in preclinical studies investigating fracture healing. The interfragmentary movement at a fracture site is critical to the course of healing and therefore demands definition in order to aptly interpret the experimental results. Estimation of this movement requires knowledge of the fixation stiffness and loading. The characteristic loading for the rat femur has been estimated, but the stiffness of fixation used in rat studies has yet to be fully described. This study aimed to determine the 6 degree of freedom stiffness of four commonly used implants, two external fixators (RatExFix and UlmExFix), a locking plate, and a locking intramedullary nail, in all degrees of freedom and estimate the interfragmentary movement under specific physiological loads...
