Purpose: Low-intensity pulsed ultrasound (LIPUS) has been used successfully to accelerate healing of fresh fractures and non-unions. It also improved callus maturation with distraction osteogenesis in animal trials. However, only few clinical studies are available to support its widespread use for the latter indication in humans.

Results: Sweat chloride measurements at day 15 had an overall positive predictive value (PPV) of 86.3%, a negative predictive value (NPV) of 65.
Background: We compared the healing response of tibial delayed unions between subjects treated with low-intensity pulsed ultrasound (LIPUS) (n = 51) and subjects treated with a sham device (n = 50). Fracture age was ≥ 4 months in all cases. Study personnel and participants were blinded to random treatment assignment throughout the study.

Objective: The authors hypothesized that exercise-induced LBP in rowers is caused by a chronic functional compartment syndrome (CFCS) of the multifidus muscle.

Objectives: The management of acromioclavicular (AC) injuries has long been debated. We analyzed our results in treating such cases using hook plates and ligament suture.
Design: : Retrospective nonrandomized study.
Phagocytosis is an essential event in the complex process of tissue repair. Here we examined the effect of low intensity pulsed ultrasound (US), which promotes fracture and wound healing, on phagocytosis by mouse macrophage cell line J774A.1 and human monocyte-derived macrophages.

The aim of this study was to explore the molecular mechanisms of the effect of low intensity pulsed ultrasound (LIPUS) on human primary macrophage functions. Macrophage phagocytosis was analyzed using fluorescein isothiocyanate (FITC)-labelled Escherichia coli (E.Coli); focal complex and extracellular matrix metalloproteinase inducer (EMMPRIN) were observed by fluorescence microscopy; the secretion of metalloproteinases (MMPs) was examined by gelatin zymography, and the expressions of EMMPRIN and extracellular signal-regulated kinases (ERKs) were detected by Western blot.

Aim: To explore the effect of low intensity pulsed ultrasound (LIPUS) on the biological behavior of macrophages to provide some theoretical foundations for its clinical application.
Methods: Human primary macrophages were obtained by using modified Ficoll-paque density gradient centrifugation combined with adherent method. The phagocytosis of macrophages was analyzed using fluorescein-labelled E.
Background: Orthopaedic surgeons are being increasingly confronted with complex ankle problems that cannot be reliably treated by conventional arthrodesis procedures. The Ilizarov technique can be an alternative salvage method in such cases.
Methods: Twenty-two Ilizarov tibiotalar arthrodeses were retrospectively reviewed.
Object: The cervical spine in a patient with ankylosing spondylitis (AS) (Bechterew disease) is exposed to maximal risk due to physical load. Even minor trauma can cause fractures because of the spine's poor elasticity (so-called bamboo spine). The authors conducted a study to determine the characteristics of cervical fractures in patients with AS to describe the standard procedures in the treatment of this condition at two trauma centers and to discuss complications of and outcomes after treatment.

We treated 21 patients with persistent infections using knee arthrodesis with a hybrid Ilizarov frame at our institution. There were 13 men and eight women ranging from 21 to 75 years (mean, 49.

It may be related to the initial fracture status or, more commonly, the surgical intervention. From 1991 to 2003, 12 patients underwent knee fusion to treat resistant infection after complex knee fractures or arthrodesis fractures using the Ilizarov method and frame.

Indications: Acute and chronic inflammatory conditions, e. g.
Soluble factors such as polypeptide growth factors, mitogenic lipids, inflammatory cytokines, and hormones are known regulators of cell proliferation. However, the effect of mechanical stimuli on cell proliferation is less well understood. Here we examined the effect of low intensity pulsed ultrasound (US), which is used to promote wound healing, on the proliferation of primary human foreskin fibroblasts and the underlying signaling mechanisms.
