We studied the rate of revision in 84 consecutive total hip replacements performed for failed osteosynthesis of femoral neck fractures and compared it with that for primary arthroplasty for osteoarthritis. The age and sex adjusted risk of prosthetic failure was 2.5 times higher after failure of fixation, but all the excess risk was in patients over 70 years of age. There were radiographic signs...

T emporomandibular joint and masticatory muscle dysfunction prior to and following bilateral sagittal split osteotomy (BSSO) of the mandible is not well documented. The effect, if any, that the type of internal fixation used has on dysfunctional symptoms is unclear. Several authors have concluded that the TMJ does not appear to be affected following a BSSO with wire osteosynthesis. 1-S However,...

The treatment of tibial plafond fractures requires careful management of the soft tissue envelope, reconstruction of the articular surface and stable fixation with minimal additional damage. Thirty cases of AO type 43 C tibial fractures were treated by transosseous osteosynthesis (Ilizarov technique). The external fixator constructs used were Ilizarov (Transosseous osteosynthesis: theoretical a...

ABSTRACT BACKGROUND Minimally invasive internal fixation is also called "biological internal fixation". This concept is used widely in the treatment of various fractures but to date, there have been no report about such application in the repair of isolated ulnar bone fractures. METHODS Eleven patients with fracture of isolated ulnar bone (four AO type 22A11 and seven AO type 22A12), mean ...

Minimally invasive plate osteosynthesis (MIPO) of the distal tibia offers several theoretical advantages compared to classic open reduction and internal fixation. A mechanically stable fracture-bridging osteosynthesis can be obtained without significant dissection and surgical trauma to the bone and surrounding soft tissues. In this retrospective study we looked at the results and complications...

In the last fifteen years the indications for osteosynthesis in the treatment oftibial fractures have increased considerably. As early as 1958 Merle d’Aubign#{233} and Franc insisted on the value of osteosynthesis in compound fractures. Since 1960 blind intramedullary nailing has been mainly adopted in the treatment of closed fractures (Zucman and Maurer 1965) and almost exclusively in the trea...

BACKGROUND The aim of this study was to evaluate the reliability of open reduction and minimally invasive plate osteosynthesis (MIPO) for anterior ring fracture combined with pubic symphysis separation and to explore the operative techniques and therapeutic efficacy. MATERIAL AND METHODS We used minimally invasive plate osteosynthesis (MIPO) to treat anterior ring fracture combined with pubic...

INTRODUCTION Ossifications after osteosynthesis of the proximal humerus are poorly described. We report a case of major and early ossifications after synthesis of a fracture dislocation of the shoulder. CASE REPORT A 57-year-old man, right-handed, bipolar schizophrenic, presented after a fall, a fracture of the head and metaphysis of the humerus from the anterior notch of posterior dislocatio...

The authors retrospectively reviewed 269 patients treated from September 2006 to August 2011 with the minimally invasive plate osteosynthesis (MIPO) technique using a universal reconstruction ribbon plate for fresh displaced midshaft fracture of the clavicle. Mean follow-up was 40.6 months. All had bony union (average healing time, 14.6 weeks). At 2-month postoperative follow-up, the mean Const...

We report positive and negative factors associated with the most commonly-used methods of reconstruction after pathological fracture of the proximal femur. The study was based on 142 patients treated surgically for 146 metastatic lesions between 1996 and 2003. The local rate of failure was 10.3% (15 of 146). Of 37 operations involving osteosynthetic devices, six failed (16.2%) compared with nin...
