Electromagnetic distal targeting system does not reduce the overall operative time of the intramedullary nailing for humeral shaft fractures

2018

Abstract Introduction We aimed to evaluate the efficacy of the use of the electromagnetic distal targeting system in treating humeral shaft fracture. Methods Patients were divided in: Group 1) patients that received a distal locking screw placement following the free-hand technique; Group 2) patients in which the distal locking screw was performed using the SURESHOT device. Results No differences were noted comparing Group 1 (freehand) [71,9 range 40–135 min] to Group 2 (SURESHOT)[70, range 25–125 min]. Conclusion The use of the EM distal targeting system doesn't reduce the overall operative time of the humeral shaft fracture fixation using IMN.

Thoracic spinal cord cavernous angioma: a case report and review of the literature

2014

Introduction: Cavernous angiomas of the spinal cord are rare vascular malformations, which account for approximately 5 to 12 percent of spinal cord vascular lesions. They usually originate in the vertebrae, with occasional extension into the extradural space, and intramedullary cavernomas, even if reported in the literature, are very rare. Case presentation: We report the case of a 34-year-old Caucasian woman affected by a thoracic intramedullary cavernous angioma. Our patient complained of 10-day history of acute dorsal pain, progressive weakness of both lower extremities, worse on the right side, a ‘pins and needles’ sensation in the abdominal region and bladder dysfunction. Magnetic reso…

Clinical performance of a new medullary humeral nail: antegrade versus retrograde insertion.

2001

Objective A new intramedullary nail system for humeral shaft fractures is evaluated to determine whether retrograde nailing is as reliable as antegrade nailing. Study design Prospective multicenter nonrandomized clinical study. Patients Eighty-four patients with acute humeral shaft fractures were nailed with the new unreamed humeral nail (UHN) system. Fifty-seven nails were introduced retrogradely, and twenty-seven antegradely. Bone healing and functional outcome were the follow-up parameters. Results The ratio of perioperative complications was equivalent for both groups, but one shaft fracture and three fractures or fissures at the entry point occurred in the group with retrograde nail in…

Virtual prototyping of a new intramedullary nail for tibial fractures

2012

In this work a new distal interlocking system has been developed which is easy to use, allows a reduction of the operating time and consequently the exposure to radiations both for surgeon and patient. The main goal of this study has been the design of a new intramedullary nail for tibial fractures able to simplify and speed up the distal locking operation phases. After a preliminary stage during which several candidate concepts have been proposed and analysed, the best solution has been developed and deeply investigated. The new system, called “expansion nail”, has been firstly modelled by setting up a full parametric CAD model and, then, tested by running non linear FEM analyses to evalua…

Presurgical role of MRI tractography in a case of extensive cervicothoracic spinal ependymoma

2017

Background: Intramedullary spinal ependymoma is a tumor, hardly characterizable with conventional magnetic resonance (MR) imaging only. MR diffusion tensor imaging (DTI) with three dimensional fiber tracking reconstructions allows the evaluation of the relationship between neoplasm and white matter fiber tracts, being a powerful tool in presurgical planning. We present DTI findings in a case of a young female with an extensive cervicothoracic spinal ependymoma. Case Description: The patient complained of a 2 month history of acute urinary retention, weakness and numbness on the lower limbs and the upper left limb. She underwent MR imaging that showed an extensive cervicothoracic spinal mass…

The challenge of open tibial shaft fractures: When tomanage with external fixation and when to useintramedullary nailing?

2020

Treatment of open tibial shaft fractures is challenging. External fixation (EF) is comparatively safe in treating these open injuries with the main advantages of easy application, minimal additional disruption, and convenient subsequent soft tissue repair. Tibial intramedullary nailing (IM) is optimal for the treatment of open tibial fractures. This study aims to report the outcomes of our multi-center experience in the management of open tibial shaft fractures, evaluating the efficacy and safety of using either the external fixation (EF) or intramedullary nailing (IM).In this study, clinical-radiographic results were evaluated in 26 cases of open fractures treated with an external fixator …

Die Röntgenstrahlenbelastung der Hände der Operateur bei Marknagelosteosynthesen

1996

Bei 41 Marknagelungen (21 unaufgebohrte und neun aufgebohrte Tibiamarknagelungen sowie vier unaufgebohrte und sieben aufgebohrte Femurmarknagelungen) trugen Operateur und 1. Assistent Ringdosimeter am dominanten Zeigefinger unter dem sterilen Handschuh. Bei Durchleuchtungszeiten von durchschnittlich 4.6 min pro Eingriff lag die mittlere Strahlenbelastung der Finger der Operateur bei 1.27 mSv und die der 1. Assistenten bei 1,19 mSv. Extrapoliert man den Gesamtmittelwert der ermittelten Strahlenbelastung der Hand der Operateure und 1. Assistenten von 1,23 mSv, wurde der gesetzlich zugelassene Grenzwert fur beruflich strahlenexponierte Personen der Gruppe A von 500 mSv erst bei 407 Marknagelos…

The outcomes of Ilizarov treatment in aseptic nonunions of the tibia stratified by treatment strategies and surgical techniques.

2020

Abstract INTRODUCTIONNonunions of the tibia, particularly those located in the distal third of the bone, are relatively common in clinical practice. There is no gold standard for the treatment of nonunions of the tibia. The purpose of our study was to assess the results of treatment with the Ilizarov method in patients with aseptic nonunions of the tibia, depending on the employed treatment strategies and surgical techniques.MATERIALS AND METHODSA total of 75patients with Ilizarov treatment of aseptic nonunions of the tibia were evaluated in the study. The patients’s mean age at the beginning of treatment was 46years.The mean follow-up period was 10years and 11months.The evaluated patients …

Metacarpophalangeal joint of the thumb arthrodesis using intramedullary interlocking screws XMCP™

2018

Abstract The study objective was to assess the results of a thumb metacarpophalangeal joint (MCPJ) arthrodesis using intramedullary interlocking screws at 25°, XMCP ™ (Extremity Medical, Parsippany, NJ). Radiographs evaluated the angle of arthrodesis, time of fusion and fixation of the implant. Clinical and functional outcomes were assessed using the DASH questionnaire and the VAS scale. Any complications found during surgery or the follow-up period were noted. We studied 9 patients. The mean follow-up was 27.6 months. Patients showed clinical and radiological evidence of fusion in an average of 8 weeks, the angle of fusion was 25°. There were no complications and no implant had to be remov…
