Does access through the pronator quadratus influence pronation strength in palmar plate fixation of distal radius fractures in elderly patients?

Introduction: Palmar plate fixation of the distal radius fracture involves dissecting the pronator quadratus (PQ). This is regardless of whether the approach is radial or ulnar to the flexor carpi radialis (FCR) tendon. It is not yet clear whether and to what extent this dissection leads to a functional loss of pronation or pronation strength.

Residual dorsal displacement following surgery in distal radial fractures: A cause for trouble?

Purpose: Distal radius fractures have great impact on activities of daily living of affected patients. Repeatedly, a non-anatomic restoration of the volar tilt can be observed in a minimum of 20% in postoperative X-ray control examinations. Hence, the question arises whether the achieved reduction is functionally acceptable, or whether a further attempt should be made to improve the surgical outcome.

[Successful in-hospital clamshell thoracotomy in a young male patient with polytrauma (ISS 57) : A case report].

Life-threatened injured patients who suffer a cardiovascular arrest after a trauma are still enormously challenging for both the paramedics and the trauma team in the clinic. This case illustrates the treatment of a 16-year-old boy who suffered a blunt abdominal trauma with a traumatic cardiac arrest followed by an open resuscitation after clamshell thoracotomy. Subsequently, the treatment after damage control is discussed regarding the current literature and recommendations for treatment.

Calcaneal fracture fixation using a new interlocking nail reduces complications compared to standard locking plates - Preliminary results after 1.6 years.

Introduction: Surgical treatment of displaced intra-articular calcaneal fractures using a standard extended lateral approach for plate fixation is frequently associated with substantial wound healing complications and infections. This matched pairs analysis compares the new minimally-invasive calcaneal interlocking nailing technique to standard locking plate fixation in terms of reduction capacity, complication rates, and functional outcomes.

Methods: Forty feet in 38 patients (mean patient age 52.

Results of geriatric distal radius fractures treated by intramedullary fixation.

Introduction: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity.

Fixation of intra-articular fractures of the distal radius using intramedullary nailing: a randomized trial versus palmar locking plates.

Background: Proposed benefits of intramedullary techniques include limited soft tissue dissection while affording sufficient stability to allow early wrist motion. The primary null hypothesis of this randomized trial was that there is no significant difference with respect to functional outcome, pain and disability between patients treated with either 2.4-mm volar locking plate fixation or intramedullary nail fixation of intra-articular fractures of the distal radius.

Proximal humeral fractures: non-operative treatment versus intramedullary nailing in 2-, 3- and 4-part fractures.

Background: Little is known about non-operative treatment of proximal humerus 4-part and severe displaced fractures as those are normally treated operatively. In this study, we present a historical collective of two level I trauma centers, where all humeral head fractures, despite displaced fractures, received non-operative treatment within a 10 years period. Functional and clinical results of 2-, 3- and 4-part fractures were compared to those after fixed angle intramedullary nailing by matched pair analysis.

Prediction of complications in a high-risk cohort of patients undergoing corrective arthrodesis of late stage Charcot deformity based on the PEDIS score.

Background: All diabetic neuroosteoarthropathy (Charcot arthropathy) treatment concepts are focused on a long-term infection-free, ulcer-free, and plantigrade sufficiently stable foot in order to avoid amputation. Reconstructive arthrodesis techniques for severe deformities are associated with high postoperative complication rates. This study reports a detailed complication analysis and provides a strategy that may help detect patients at risk for a complicated postoperative course.

The standardized creation of a lumbar spine vertebral compression fracture in a sheep osteoporosis model induced by ovariectomy, corticosteroid therapy and calcium/phosphorus/vitamin D-deficient diet.

Introduction: Vertebral compression fractures (VCFs) are one of the most common injuries in the aging population presenting with an annual incidence of 1.4 million new cases in Europe. Current treatment strategies focus on cement-associated solutions (kyphoplasty/vertebroplasty techniques).

Intrabody application of eptotermin alpha enhances bone formation in osteoporotic fractures of the lumbar spine; however, fails to increase biomechanical stability - results of an experimental sheep model.

This study analyses the effect of eptotermin α application into fractured vertebrae. It is hypothesized that eptotermin α is capable to enhance bony healing of the osteoporotic spine. In 10 Merino sheep osteoporosis induction was performed by ovariectomy, corticosteroid therapy and calcium/phosphorus/vitamin D-deficient diet; followed by standardized creation of lumbar vertebral compression fractures (VCFs) type A3.

Late corrective arthrodesis in nonplantigrade diabetic charcot midfoot disease is associated with high complication and reoperation rates.

Introduction: Charcot arthropathy may lead to a loss of osteoligamentous foot architecture and consequently loss of the plantigrade alignment. In this series of patients a technique of internal corrective arthrodesis with maximum fixation strength was provided in order to lower complication rates.

Materials/methods: 21 feet with severe nonplantigrade diabetic Charcot deformity Eichenholtz stages II/III (Sanders/Frykberg II/III/IV) and reconstructive arthrodesis with medial and additional lateral column support were retrospectively enrolled.

Bony healing of unstable thoracolumbar burst fractures in the elderly using percutaneously applied titanium mesh cages and a transpedicular fixation system with expandable screws.

Introduction: There is a high incidence of vertebral burst fractures following low velocity trauma in the elderly. Treatment of unstable vertebral burst fractures using the same principles like in stable vertebral burst fractures may show less favourable results in terms of fracture reduction, maintenance of reduction and cement leakage. In order to address these shortcomings this study introduces cementless fixation of unstable vertebral burst fractures using internal fixators and expandable intravertebral titanium mesh cages in a one-stage procedure via minimum-invasive techniques.

Cementless fixation of osteoporotic VCFs using titanium mesh implants (OsseoFix): preliminary results.

Introduction: Vertebral compression fractures (VCFs) affect 20% of people over the age of 70 with increasing incidence. Kypho-/vertebroplasty as standard operative procedures are associated with limitations like cement leakage, limited reduction capabilities, and risk for adjacent fractures. To address these shortcomings, we introduce a new minimal invasive cementless VCF fixation technique.

Acromioclavicular joint dislocations: radiological correlation between Rockwood classification system and injury patterns in human cadaver species.

Introduction: The classification system of Rockwood and Young is a commonly used classification for acromioclavicular joint separations subdividing types I-VI. This classification hypothesizes specific lesions to anatomical structures (acromioclavicular and coracoclavicular ligaments, capsule, attached muscles) leading to the injury. In recent literature, our understanding for anatomical correlates leading to the radiological-based Rockwood classification is questioned.

Finding the needle in the haystack: differentiating "identical" twins in paternity testing and forensics by ultra-deep next generation sequencing.

Monozygotic (MZ) twins are considered being genetically identical, therefore they cannot be differentiated using standard forensic DNA testing. Here we describe how identification of extremely rare mutations by ultra-deep next generation sequencing can solve such cases. We sequenced DNA from sperm samples of two twins and from a blood sample of the child of one twin.

Angular stable multiple screw fixation (Targon FN) versus standard SHS for the fixation of femoral neck fractures.

Objective: Head-preserving fracture care especially for the elderly may be complicated by acetabular screw penetration, cut out, delayed union or femoral head necrosis. The following comparative study analyses whether a new angular stable device may overcome these shortcomings.

Material And Methods: The Targon FN plate (BBraun/Aesculap, Germany) employs up to four angular stable telescoping screws for the fixation of the head fragment.

Intramedullary medial column support with the Midfoot Fusion Bolt (MFB) is not sufficient for osseous healing of arthrodesis in neuroosteoarthropathic feet.

Introduction: To address midfoot instability of Charcot disease a promising intramedullary implant has recently been developed to allow for an arthrodesis of the bones of the medial foot column in an anatomic position. We report on a group of patients with Charcot arthropathy and instability at the midfoot where the Midfoot Fusion Bolt had been employed as an implant for the reconstruction of the collapsed medial foot column.

Material And Methods: A total of 7 patients (median age 56.

Non-bridging external fixation employing multiplanar K-wires versus volar locked plating for dorsally displaced fractures of the distal radius.

Background: The aim of this study was to compare non-bridging external fixation to palmar angular stable plating with respect to radiological outcome, wrist function, and quality of life.

Methods: One hundred and two consecutive patients (mean age: 63 years) were enrolled in the study. Fifty-two patients were randomized for plate osteosynthesis (2.
