Accuracy of a hexapod parallel robot kinematics based external fixator.

Background: Different hexapod-based external fixators are increasingly used to treat bone deformities and fractures. Accuracy has not been measured sufficiently for all models.

Methods: An infrared tracking system was applied to measure positioning maneuvers with a motorized Precision Hexapod® fixator, detecting three-dimensional positions of reflective balls mounted in an L-arrangement on the fixator, simulating bone directions.

Polyaxial Locked Implants in the Treatment of Type Vancouver B1 Periprosthetic Fractures of the Femur: Retrospective Clinical Examination in 58 Cases with Review of the Literature.

We concluded a retrospective study of the outcomes of a consecutive series of Vancouver B1 and C femoral injuries using two specific locked implants. The study center is a dedicated trauma hospital with a large catchment area. Over a five-year period we treated 58 patients with a periprosthetic fracture of the femur with an angular stable plate, defined as the index procedure.

Operative Treatment and Soft Tissue Management of Open Distal Tibial Fractures - Pitfalls and Results.

Open tibial fractures usually result from high-energy trauma. Severe soft-tissue injuries are often combined with open fractures of the distal tibia. A consecutive series of 42 patients with open extraarticular distal tibial fractures (Gustilo I-IIIc) operated on between July 2006 and February 2009 were included in the study reported here.

Treatment of Distal Lower Leg Fractures: Results with Fixed-Angle Plate Osteosynthesis.

Twenty-five patients with closed distal tibial fractures were treated with a fixed-angle (locked) plate osteosynthesis. The study period was from 1.1.

Is the Wave Plate Still a Salvage Procedure for Femoral Non-union? Results of 75 Cases Treated with a Locked Wave Plate.

Objective: To analyse the results of the treatment of aseptic femoral non-unions using a singular locked implant.

Design: Consecutive case series.

Setting: A level-1 trauma center with a high number of specialist referrals.

Unstable Cervical Spinal Injury in Children - Case Report and Review of the Literature.

Large studies about the management of pediatric patients with unstable flexion-distraction injuries of the midcervical spine are rare. We present the case of a 12-year-old girl who sustained a cervical spinal injury with unilateral facet dislocation and discuss details and problems of diagnostic procedures and treatment in the light of the recent literature. The management and pitfalls of a unilateral facet dislocation in a child are summarized.

Septic arthritis of the knee after anterior cruciate ligament surgery: a stage-adapted treatment regimen.

Background: Septic arthritis is a rare complication after anterior cruciate ligament surgery. All case series reported so far have been retrospective, and case numbers of septic arthritis have ranged from 4 to 11.

Hypothesis: A stage-adapted treatment regimen for septic arthritis after anterior cruciate ligament surgery can provide reliable results.

Cardial gunshot injury: treatment in a trauma hospital without a cardiac unit.

Gunshot injuries to the chest often require urgent admission to the nearest hospital, because of the cardiorespiratory status, transfer to a hospital without a cardiothoracic unit might be unsafe. In this case, a male patient was transferred to the nearest hospital on being shot through the heart. On admission, he was in shock, and immediate surgery was performed.

Delayed and non-union of the humeral diaphysis--compression plate or internal plate fixator?

In a retrospective study, two groups of patients with delayed or non-union of the humeral diaphysis were compared. In group A, a 4.5-mm low-contact dynamic compression plate (LCDCP) was used for internal fixation and in group B, an internal plate fixator with locked screws was used.
