RATIONALE: Pelvic malunion is a rare complication and is technically challenging to correct owing to the complex three-dimensional (3D) geometry of the pelvic girdle. Hence, precise preoperative planning is required to ensure appropriate correction. Reconstructive surgery is generally a 2- or 3-stage procedure, with transiliac osteotomy serving as an alternative to address limb length discrepancy. PATIENT CONCERNS: A 38-year-old female patient with a Mears type IV pelvic malunion with previous failed reconstructive surgery was admitted to our department due to progressive immobilization, increasing pain especially at the posterior pelvic arch and a leg length discrepancy...

PURPOSE: The objective of surgical fracture management is to reduce and fixate fractures accurately and rapidly. Two osteosynthesis plates are usually used in the treatment of mandibular angle fractures to enhance torsional stiffness. We conducted biomechanical tests under static and cyclic loading to assess whether a single locking plate is as efficacious as two conventional plates in the osteosynthesis of mandibular angle fractures. MATERIALS AND METHODS: Fracture gaps were created in synthetic mandible replicas...

INTRODUCTION: Bilateral flail chest injuries are challenging in treatment and comparatively often require an operative stabilization of the anterior chest wall to re-establish normal physiological conditions of the chest wall in shape and statics. Various procedures have been described which are technically sophisticated for the surgeon. Consequently there is an increasing interest in potentials of operative care and their effectiveness on the anterolateral chest wall. MATERIALS AND METHODS: 12 Human cadavers were prepared and the natural Sternum Position (NP) was marked...

INTRODUCTION: Metastases to the proximal femur are usually managed surgically by tumor resection and reconstruction with an endoprosthesis, or by fixation with osteosynthesis. Still controversy remains regarding the most appropriate surgical treatment. We posed the following questions: (1) Is the frequency of surgical revision greater in patients treated with internal fixation than endoprosthetic reconstruction, and (2) Do complications that do not require surgery occur more frequently in patients treated with internal fixation rather than in those with endoprosthetic reconstruction? MATERIALS AND METHODS: A systematic review was performed of those studies reporting on surgical revision and complication rates comparing the two surgical methods...

Introduction: Humerus shaft fractures in adults can be managed conservatively with functional braces or operatively with plate osteosynthesis or with intramedullary nailing. Conventionally humerus intramedullary nailing is done either using humerus interlocking nails or Enders nails. In this study we analyse the outcome of humerus shaft fractures (upper and middle third) managed with closed ante-grade intramedullary titanium elastic nailing in terms of union rates, union time, functional results and complications...

REVIEW
Daniel E Perez, Aaron Liddell
Controversy has accompanied orthognathic surgery since its adaptation for the correction of dentofacial deformities. With the development of less invasive and less morbid osteotomy designs, questions regarding overall osteotomy stability have abounded. The transition from prolonged intermaxillary fixation and wire osteosynthesis to rigid internal fixation has spurred questions regarding the most effective fixation technique, and challenged previously accepted hierarchies of stability. These questions represent only the surface of a sea of debate and discussion, as measures have been taken to optimize patient outcome, minimize patient morbidity, and maximize operating room productivity...

Biomimetic surface modifications of titanium implants using the Arg-Gly-Asp-sequence (RGD) are promising to accelerate bone healing in cases of medical implants. Therefore, we compared the impact of linear and cyclic RGD (l- and c-RGD) covalently coupled onto titanium surfaces on the osseous response in vitro and in vivo. In vitro, osteoblasts' behaviour on different surfaces (unmodified, amino-silanized (APTES), l- and c-RGD) was analysed regarding adhesion (fluorescence microscopy), proliferation (resazurin stain) and differentiation (RT-PCR on alkaline phosphatase (AP) & osteocalcin (OC))...

BACKGROUND: Every endosseous dental implant is dependent on an adequate amount and quality of peri-implant hard and soft tissues and their fully functional interaction. The dental implant could fail in cases of insufficient bone and soft tissues or due to a violation of the soft to hard tissues to implant shoulder interface with arising of a secondary bone loss. METHOD: To overcome this biological weak-spot, we designed a new implant that allows for multi vector endosseous anchorage around the individual underlying bone, which has to be scanned by computed tomography (CT) or Cone beam CT (CBCT) technique to allow for planning the implant...

BACKGROUND: In recent years, spinal surgery has incorporated the many advantages of navigation techniques to facilitate the placement of pedicle screws during osteosynthesis, mainly for degenerative diseases. However, spinal intradural tumors are not clearly visible by intraoperative fluoroscopy or computed tomography scans, thereby making navigation necessary. OBJECTIVE: To evaluate the use of spinal navigation for the removal of intradural and spinal cord tumors using spinal magnetic resonance imaging (MRI) merged with intraoperative 3-dimensional (3-D) fluoro images...

In this report, we describe the case of a healthy 37-year-old male patient without a history of disease, who developed atraumatic bilateral fracture of the femoral neck. Radiological and blood investigations revealed osteopenia and severe vitamin D deficiency (7.42 ng/mL), respectively, but patient had no apparent risk factors for insufficiency fracture. Bilateral osteosynthesis was obtained using cannulated screws and laboratory findings improved after vitamin D supplementation. This case highlights the effect of vitamin D deficiency on demineralization in a young male patient...

INTRODUCTION: In performing surgery for fractures of the pelvis and acetabulum, various surgical approaches have been introduced with their own advantages and drawbacks. The extensile nature of ilioinguinal approach gives excellent exposure but was related to wound healing problems. Modified stoppa has a higher difficulty and poses a risk for neurovascular injury. In this study, we elaborate our experience using the Modified Stoppa approach with additional lateral window while adding few modifications to simplify the procedure and facilitate future implant removal...
