BACKGROUND: The limited evidence available on the diagnosis and treatment of olecranon and prepatellar bursitis indicates nationally varying treatment approaches. Therefore the aim of this study was to survey the current treatment concepts of olecranon and prepatellar bursitis in Austria. MATERIAL AND METHODS: An online questionnaire comprising of demographic data, questions regarding diagnostics and differentiation between septic bursitis (SB) and non-septic bursitis (NSB) as well as two case reports for therapy appraisal were sent to members of the Austrian Society of Orthopaedics and Orthopaedic Surgery (ÖGO) and the Austrian Society of Traumatology (ÖGU)...

BACKGROUND: Spine injuries, a common component in polytrauma, are relatively rare in pediatric patients. Previous studies mainly described injuries to the cervical region, whereas information of injury patterns to the thoracic and lumbosacral region lack in the current literature. The aim of this study was to determine the incidence and characteristics of polytraumatized children and associated spine injuries in different pediatric development ages. METHODS: A cohort review of all pediatric patients with the diagnosis of polytrauma and associated spine injury, admitted to a urban Level I trauma center, was conducted over an 18-year period from January 1992 to December 2010...

BACKGROUND: Although the integral role of ED thoracotomy for open cardiac massage has been extensively reviewed in adult literature, this "heroic maneuver" remains very controversial and greatly debated in children. METHODS AND RESULTS: A retrospective cohort review of emergency thoracotomies in children, performed at a European Level I trauma center between 1992 and 2008 was undertaken. Clinical manifestation, injury mechanism and surgical treatment were described, with special regard to prognostic factors and outcome...

BACKGROUND: Civilian gunshot injuries to the head are relatively rare in the irenical European Union, and studies of treatment and outcomes are seldom for this region in the current literature. METHODS: A cohort of 85 patients with civilian head gunshot injuries, who were admitted to our University hospital over a period of 16 years, was reviewed retrospectively. Clinical manifestation, computed tomography scan findings, and surgical treatment were described, with special regard to prognostic factors and outcome...

Based on biomechanical cadaver studies, anatomic double-bundle reconstruction of the anterior cruciate ligament (ACL) was introduced to achieve better stability in the knee, particularly in respect of rotatory loads. Previously, the success of ACL reconstruction was believed to be mainly dependent on correct positioning of the graft, irrespective of the number of reconstructed bundles for which computer-assisted surgery was developed to avoid malpositioning of the tunnel. The aim of the present study is to compare rotational and translational stability after computer-navigated standard single-bundle, and anatomic double-bundle ACL reconstruction...

BACKGROUND AND OBJECTIVES: The use of ultrasonography in regional anesthetic blocks has rapidly evolved over the past few years. It has been speculated that ultrasound guidance might increase success rates and reduce complications. The aim of our study is to compare the success rate and quality of interscalene brachial plexus blocks performed either with direct ultrasound visualization or with the aid of nerve stimulation to guide needle placement. METHODS: A total of 160 patients (American Society of Anesthesiologists physical status classification I-III) scheduled for trauma-related upper arm surgery were included in this randomized study and grouped according to the guidance method used to deliver 20 mL of ropivacaine 0...

To validate the hypothesis that healing of fractures can be accelerated by oral administered L-arginine a guinea-pig model was chosen. A diaphyseal defect fracture was established in the right femur of each of the 32 small animals and stabilized. According to randomization groups the oral administration was realized (2 or 4 weeks medication / solvent). The following biomechanical variables were measured after 4 weeeks in 32 right femora and the corresponding uninjured left femora. The measurement for the healed femur was individually compared with that of the uninjured femur in each animal; bending, force (necessary for refracture) and energy (necessary for refracture)...

A 45-year-old homeless male patient did not return for follow-up for routine removal 72 days after an external fixator had been placed for a grade II open fracture of the proximal tibia. Ten years later, he was accidentally referred to our institution for newly incurred fractures of the femoral neck on the same side and also for an opposite-side medial malleolus fracture. The patient was still homeless, with signs of poor personal hygiene, but the original external fixator was in place. Union of his previous proximal tibia fracture had occurred, and there were no signs of any pin-tract infection...

BACKGROUND: The known biological activities of nitric oxide suggest a role in bone healing. We hypothesized that L-arginine, a source of nitric oxide, expedites the healing process of stabilized diaphyseal defects. TYPE OF STUDY: Prospective blinded animal study. METHODS: Using a guinea-pig model, a 7 mm diaphyseal and periosteal defect was produced in the right femur and splinted intramedullary with a 1.4 mm K-wire. The guinea pigs (n = 44) were treated orally in three parallel groups: two treatment groups received high doses of L-arginine (one group for 2 weeks and the other for 4 weeks) and a control group received vehicle only...

PURPOSE: Testing an applicable intraoperative system for measuring surface pressure in knee joints, simulating as accurately as possible operating theatre conditions. TYPE OF STUDY: Cadaver study. METHODS: Pressure probes were introduced into the knee joints medially and laterally (K 6900 quad probes) in five cadavers, providing real-time data with computerized data recording (K-scan system, manuf. Tekscan Inc., South Boston, MA). The initial position of the knee was flexed and hanging, as in a leg holder...

Prospectively, 119 patients were pursued clinically and by follow-up-arthroscopy for the occurrence of a "cyclops syndrome" after ACL reconstruction with a patellar tendon autograft, augmented by LAD. Twenty-one patients showed nodular formations. Ten of these (group 1) developed early clinical evidence of a "cyclops syndrome" with a mean extension deficit of 19 degrees before follow-up-arthroscopy, on average 5.9 months after the index operation. The nodular formations found and excised during débridement had a hard consistency...

Long-term clinical results and short-term arthroscopic and microscopic findings from two augmented reconstruction procedures for the ruptured anterior cruciate ligament are reported. The braided polypropylene ligament augmentation device (Kennedy model) was used with temporary double-end fixation in 279 patients to augment the attachment of the anterior cruciate ligament after acute proximal rupture and in 315 patients to augment a bone-tendon-bone autograft, mainly after chronic instability. Check arthroscopy was performed and the metal fixation hardware was removed after a mean of 11 months...

The long-term results (five-to eight-year follow-up evaluation) of 66 patients with high proximal ruptures of the anterior cruciate ligament (ACL) who were treated operatively are presented in a retrospective and uncontrolled study. Technique of surgery was the reinsertion of the ACL in a multiple suture loop technique, augmented with Kennedy-LAD (ligament augmentation device) on over the top route in temporary double-end fixation. This technique was used in patients with proximal rupture of the anterior cruciate ligament found at arthroscopy...

In an experimental study various synthetic augmentation devices for knee ligament surgery were tested in a servo-mechanical universal tensile testing machine under uniaxial loading. Two tests were done to elucidate the mechanical behaviour: stress relaxation and stress-strain relationship. Regarding the point of failure or rupture, the strongest ligament was the Trevira at 1800 N, followed by the 8-mm-wide Kennedy LAD at 1720 N. At a working load of 500 N the Gore-tex band, the Trevira, and the Kennedy-LAD stretched by between 2% and 3%...

97 patients who had their ACL replaced with ligamentum patellae transplant augmented with LAD were reviewed arthroscopically after an average period of 9.1 months (4-22 months). 52 patients whose metal implants have been removed are virtually symptom-free clinically (no swelling, stable knee joint, extension limitation of less than 5 degrees, less than 10 degrees limitation of flexion). Arthroscopy on these 52 patients revealed the following; no abnormalities in 37, 11 cases of cartilage lesions, 1 case of medial meniscal tear and 7 cases of LAD tears...

To compare results in knee ligament surgery between different surgeons and between different centers, too, is difficult. We investigated if an improvement can be achieved by using easy to handle methods of measurement. The long-term results of 180 patients who underwent ACL surgery between 1983 and 1986 (n = 191) were evaluated. For international comparing of our results we used the scoring of the OAK (Orthopädische Arbeitsgemeinschaft Knie). In addition stability was measured by use of the KT-1000 arthrometer and function by "one leg hop for distance"...
