Currently, antegrade intramedullary nailing and minimally invasive plate osteosynthesis (MIPO) represent the main surgical alternatives in distal tibial fractures. However, neither choice is optimal for all bony and soft tissue injuries. The Retrograde Tibial Nail (RTN) is a small-caliber prototype implant, which is introduced through a 2-cm-long incision at the tip of the medial malleolus with stab incisions sufficient for interlocking. During this project, we investigated the feasibility of retrograde tibial nailing in a cadaver model and conducted biomechanical testing. Anatomical implantations of the RTN were carried out in AO/OTA 43 A1-3 fracture types in three cadaveric lower limbs. B…

Effects of prolonged and maintenance strength training on force production, walking, and balance in aging women and men

2012

To examine effects of 21-week twice/week strength training (ST) period followed by an additional 21-week twice or once/week ST period on force production, walking and balance in aging people. Seventy-two women (58 ± 7 years; W) and 63 (58 ± 6 years) men (M) were randomized for the first 21-week ST period: STW and STM, control (C) CW and CM. Training participants were randomized for the second 21-week ST period: once/week STWx1 and STMx1, twice/week STWx2 and STMx2. LegPress, isometric leg extension rate of force development (RFD), walking time, and balance. First 21-week ST period: leg press, RFD, balance, and walking improved significantly in STW and STM. Second 21-week ST period: leg pres…

Intraoperative Sonographie bei lumbalen Bandscheibenvorfällen

2008

UNLABELLED Intraoperative ultrasound of the spine has been used in neurosurgery (tumours) and traumatology (reposition of fractured vertebral bodies fragments). AIM To describe initial experiences with this method and to document the opportunities and problems. METHOD 24 nucleotomies were documented and evaluated. Sonography was performed using a 7.5 MHz sector probe and a typical surgical approach. RESULTS In 21 of 24 cases, imaging of intraspinal structures was possible. The complete extraction of the herniated disk could be documented. In 3 cases the examination failed because the probe was too large to be pushed down between the spinous processes and the wound retractor to the operative…

Maximal isometric muscle strength and anthropometry in 75-year-old men and women in three Nordic localities

2007

Isometric maximal strength of hand grip, elbow flexion, knee extension, trunk extension and trunk flexion was studied in representative samples of 75-year-old residents of 3 Nordic localities: Glostrup in Denmark, Gothenburg in Sweden and Jyvaskyla in Finland. The study forms a part of a wider comparative research project analyzing the functional capacity and health of 75-year-olds in these towns. The strength measurements were carried out using standardized techniques and identical dynamometers. The results showed that the strength values of the limb muscles were significantly lower among the 75-year-olds in Jyvaskyla, both in absolute values and in relative units (N/kg body mass). For the…

Kinder und Jugendliche mit neurogener Blasenfunktionsst�rung

2004

After the failure of conservative treatment in patients with neurogenic bladders, urinary diversion is a viable compromise between the urologist's concerns and the patient's desire, as the upper urinary tract can be protected in the long-term and high continence rates can be provided. This can be achieved with an acceptable complication rate. Our indications for orthotopic bladder augmentation or substitution involve patients with a good orthopedic condition and mobility, who find it easy to perform CISC through the urethra. A continent umbilical stoma offers a good alternative in obese, immobile or wheelchair bound patients. The serous lined extramural tunnel technique has proven to be sup…

Effects of exercise training on oxygen uptake in coronary heart disease: a systematic review and meta-analysis

2010

It is not known to what extent exercise programs increase maximal oxygen uptake (VO(2max)) in patients with coronary heart diseases (CHD). The purpose of this study is to determine the effect of exercise interventions on VO(2max) in subjects with CHD. Database search of randomized controlled trials was conducted from PubMed. Studies were included that reported the characteristics and effects of exercise interventions in subjects with CHD, included a non-exercise control group and measured VO(2max) using direct measurement method. Eighteen studies were eligible. Exercise interventions increased VO(2max) by 2.6 +/- 1.6 and 0.3 +/- 1.4 mL/kg/min in the training and control groups, respectively…

Medial Patellar Instability: A Little Known Cause of Anterior Knee Pain

2014

Anterior knee pain (AKP) is one of the most common patient complaints heard by orthopedic surgeons. A wide variety of causes of AKP have been ascribed to it. Medial patellar instability (MPI) is an objective condition with its own personality provoking incapacitating AKP that should be included in the differential diagnosis of AKP patients, above all in disabling AKP patients after realignment surgery. However, this condition can be difficult to diagnose because it is not well described in the medical literature. Its clinical repercussion was identified at the end of the 1980s. We can now state that it is an objective cause of AKP and that it is more frequent than we had thought, although i…

Effects of power training on neuromuscular performance and mechanical efficiency

2007

Effects of power training with stretch-shortening cycle (SSC) exercises on mechanical efficiency (ME) were investigated with 9 young women who trained 3 times a week for 4 months. The training included various types of jumping exercises. Before and after the training as well as after the detraining (2 months) the subjects performed 6 different submaximal exercises with a special sledge apparatus. Each exercise involved 60 muscle actions lasting for a total of 3 min per testing condition. The work intensities were determined individually according to the recordings of distance obtained during the single maximal concentric exercises. The training caused the greatest changes of ME in condition…

Acute neuromuscular and hormonal responses during contrast loading: Effect of 11 weeks of contrast training

2009

The purpose of this study was to assess (1) acute neuromuscular and endocrine responses during a contrast loading protocol and (2) how these acute responses are possibly influenced by 11 weeks of contrast training. Contrast loading tests consisting of 4 sets of 80% 1 RM back squat and 4 sets of squat jump (SJ) were performed before and after training. Bilateral isometric leg extension (LE) assessed the impact of loading on isometric variables pre-, mid-, and post-loading. Potentiated SJ performance was observed in set 2 (4.6%, P<0.05), before training only. Greater indications of fatigue were observed in SJ, isometric force, and vastus lateralis (VL) activation after training (P<0.05). Trai…
