The incidence of femoral fracture on hip prosthesis is increasing. Plate fixation is the method of choice when the prosthesis is stable. In fracture with proximal extension, the quality of the bone fixation is critical and, despite the development of anatomic plates, may be endangered when there are too few proximal screws. To resolve this issue, we recommend using a reversed LCP™ anatomic dist...

The purpose of this study was to compare outcomes and complications of clavicular hook plate and Kirschner tension band wiring for fixation of unstable lateral clavicle fractures. The surgical outcomes of 92 consecutive patients (mean age, 49.30 ± 15.54 years) with unstable fractures of the lateral clavicle treated using AO clavicle hook plates were compared with those of 24 patients (mean age,...

The Locking Compression Plate (LCP), in combination with the LISS and the PHILOS, is part of a new plate generation requiring an adapted surgical technique and new thinking about commonly used concepts of internal fixation using plates. The following guidelines are needed to avoid failures and possible complications in the hands of surgeons not yet confident with the new implant philosophy. The...

This study aims to evaluate the biomechanical mechanism of fixation systems in the most frequent T-shaped acetabular fracture using finite element method. The treatment of acetabular fractures was based on extensive clinical experience. Three commonly accepted rigid fixation methods (double column reconstruction plates (P × 2), anterior column plate combined with posterior column screws (P + PS...

BACKGROUND Operative treatment of displaced pediatric midshaft clavicle fractures has become increasingly popular, despite lack of evidence that surgical management leads to superior outcomes. Complications, such as plate irritation necessitating removal and wound infection, have been reported in adults. The purpose of this study was to evaluate complications after plate fixation of midshaft cl...

OBJECTIVE The purpose of this study was to analyze and compare the mechanical characteristics of a new iliosacral fixation technique (bilateral S1 pedicle fixation through a transiliac locked plate) for bilateral sacroiliac dislocations with other previously described methods. METHODS Bilateral sacroiliac dislocations were created in 21 pelvic models and divided into three different fixation ...

BACKGROUND Expandable screws have greater pullout strength than conventional screws. The purpose of this study was to compare the biomechanical stability provided by a new built-in expandable anterior spinal fixation system with that of 2 commonly used anterior fixation systems, the Z-Plate and the Kaneda, in a porcine partial vertebral corpectomy model. METHODS Eighteen porcine thoracolumbar...

Locked plate technology has evolved in an effort to overcome the limitations associated with conventional plating methods, primarily for improving fixation in osteopenic bone. The development of screw torque and plate-bone interface friction is unnecessary with locked plate designs, significantly decreasing the amount of soft tissue dissection required for implantation, preserving the periostea...

BACKGROUND Locking plate fixation is increasingly used for first metatarsophalangeal joint (MTP-I) arthrodesis. There are still few comparable clinical data regarding this procedure. In this study we aimed to compare the clinical and radiographical outcomes of crossed-screws, locking and non-locking plate fixation with lag screw for first metatarsophalangeal joint arthrodesis. METHODS A total...

Quantitative strength analysis of first metatarsophalangeal joint arthrodesis was performed using two fixation techniques: a small 6-hole plate with an interfragmentary screw or two crossed lag screws. Twelve matched-pair fresh-frozen cadaveric specimens (24 trials) were used for direct comparison of each of the two fixation techniques. All joint surfaces were prepared with power conical reamer...
