Neurosurgical devices are increasingly used. With it, neurosurgical device-related infections gain relevance. As biofilms are involved in implant-associated infections the diagnosis and treatment is challenging and requires specific anti-biofilm concepts and management algorithms. Areas covered: The literature concerning the management of neurosurgical device-associated infections is scarce and heterogeneous treatment concepts are discussed, but no standardized diagnostic and treatment procedures exist. Therefore, we emphasize extrapolating management strategies predominantly from orthopedic device-associated infections, where the concept is better established and clinically validated...

BACKGROUND: Shoulder arthroscopic arthrodesis is an uncommon and non-standardized procedure. Results are poorly evaluated. We describe the findings in 8 patients who underwent shoulder arthroscopic arthrodesis for brachial plexus injury. METHODS: The humeral head and glenoid were excised through standard arthroscopic portals. A Hoffmann external fixator and cannulated screws were used to stabilize the shoulder. Standard clinical assessment and radiographic evaluation were performed each month until bony fusion occurred...

Control of knee motion in small animal models is necessary to study the effect of mechanical load on the healing process. This can be especially challenging in mice, which are being increasingly used for various orthopedic reconstruction models. We explored the feasibility of botulinum toxin (Botox; Allergan, Dublin, Ireland) paralysis and a newly designed external fixator to restrict motion of the knee in mice undergoing anterior cruciate ligament (ACL) reconstruction. Nineteen C57BL/6 mice were allocated to two groups: (1) Botox group (n = 9) and (2) external fixator group (n = 10)...

BACKGROUND: To evaluate the efficacy of arthrodiastasis for Legg-Calve-Perthes disease. METHODS: Arthrodiastasis was conducted using external fixator devices (Orthofix) in 7 patients at least 8 years of age with a diagnosis of Legg-Calve-Perthes disease. The average follow-up was 80 months (range, 32 to 149 months), and their average age was 9.1 years (range, 8 to 12 years). The results of treatment were evaluated by measuring the degree of hip pain and the range of motion of the hip at 6 months after the operation and comparing the values with preoperative measurements...

A finger rendered unstable due to loss of metacarpal head can be stabilized by creating a synostosis at the base of the proximal phalanx of the affected finger with the adjacent normal finger. A cortico cancellous graft bridges the two adjacent proximal phalanges at their bases which are temporarily stabilized with an external fixator. The procedure can be done for, recurrence of giant cell tumor of metacarpal and for traumatic metacarpal loss. The procedure and long term follow up of one patient is presented who had giant cell tumor...

Ankle fractures are accompanied by a syndesmotic injury in about 10% of operatively treated ankle fractures. Usually, the total rupture of the syndesmotic ligaments with an external rotation force is associated with a Weber type B or C fracture or a Maisonneuve fracture. The clinical assessment should consist of a comprehensive history including mechanism of injury followed by a specific physical examination. Radiographs, and if in doubt magnetic resonance imaging, are needed to ascertain the syndesmotic injury...

REVIEW
Youichi Yasui, Charles P Hannon, Dexter Seow, John G Kennedy
Ankle arthrodesis is a common treatment used for patients with end-stage ankle arthritis (ESAA). The surgical goal of ankle arthrodesis is to obtain bony union between the tibia and talus with adequate alignment [slight valgus (0°-5°)], neutral dorsiflexion, and slight external rotation positions) in order to provide a pain-free plantigrade foot for weightbearing activities. There are many variations in operative technique including deferring approaches (open or arthroscopic) and differing fixation methods (internal or external fixation)...

Anabaena sp. PCC 7120 is a nitrogen-fixing filamentous cyanobacterium. Under nitrogen limiting conditions, a fraction of the vegetative cells in each filament terminally differentiate to non-growing heterocysts. Heterocysts are metabolically and structurally specialized to enable O2-sensitive nitrogen fixation. The functionality of the filament, as an association of vegetative cells and heterocysts, is postulated to depend on metabolic exchange of electrons, carbon and fixed nitrogen. In the present work, we compile and evaluate a comprehensive curated stoichiometric model of this two-cell system, with the objective function based on the growth of the filament under diazotrophic conditions...

To investigate the underlying mechanisms that control long-term recovery of tundra carbon (C) and nutrients after fire, we employed the Multiple Element Limitation (MEL) model to simulate 200-yr post-fire changes in the biogeochemistry of three sites along a burn severity gradient in response to increases in air temperature, CO2 concentration, nitrogen (N) deposition, and phosphorus (P) weathering rates. The simulations were conducted for severely burned, moderately burned, and unburned arctic tundra. Our simulations indicated that recovery of C balance after fire was mainly determined by the internal redistribution of nutrients among ecosystem components (controlled by air temperature), rather than the supply of nutrients from external sources (e...

Kinking of the catheter due to excessive rotation is not a rare complication. However, percutaneous retrieval of a kinked catheter can be difficult. The key to bailout is fixation of the catheter tip. Herein, we present a 78-year-old woman who had this complication during transradial angiography. Retrieval using several previously reported techniques was unsuccessful. We finally retrieved the kinked catheter by fixing the tip of the catheter, using external and internal compressions. The former comprises manual compression on the axillary artery, while the latter comprises deployment of a balloon catheter via another puncture site...

Infection in a clavicle fracture is uncommon, but remains a challenging problem. A paucity of soft tissue coverage often combined with significant displacement and interfragmentary movement add complexity to an already difficult situation for effective infection treatment. External fixation in principle offers a means of achieving fracture stability, while the infection is being eradicated. We present the case of a closed clavicle fracture, initially treated conservatively, that presented 5 weeks later with infection...

M Rongières
The use of external fixation or internal plating to bridge communitive fractures of the distal radius is discussed based on a review of prospective and meta-analysis studies. Distraction by an external fixator is not advised (ligamentotaxis) because of the high incidence of complex regional pain syndrome and the destabilization of bone and ligaments surrounding the intra-articular fracture site. The external fixator must be used as a neutralization device and supplemented with K-wire or volar plate fixation...

Management of complex intra-articular fractures of the distal radius in young active patients must aim to restore normal anatomy. For optimal planning of the surgical procedure, a thorough analysis of the fracture with appropriate radiological exams and diagnosis of frequently associated lesions are necessary. Surgical management involves use of various types of internal or external fixation. Routine use of standardized analysis tools for these fractures along with prospective follow-up should allow us to define guidelines for each situation in the near future...

Distal radius fractures (DRF) are common. Good outcomes are the result of appropriate initial treatment (immobilization, external fixation, percutaneous pinning or open reduction and internal fixation) and rehabilitation adapted to this treatment. When started immediately, rehabilitation of DRF prevents complications due to immobilization, surgery and a non-controlled healing process. Splints play an important role at all stages of rehabilitation.
