Conservative Management for Odontoid Cervical Fractures: Halo or Rigid Cervical Collar?
2016
Odontoid fractures are the most common fractures of the cervical spine, especially in the elderly. They account for approximately one third of cervical spine fractures, and with the aging of the world population, the incidence and clinical and social relevance of such pathology are likely to increase. Odontoid fractures may occur from high-energy mechanisms, particularly in younger patients, but low-energy trauma may be the causative factor in the geriatric population. Overall, the treatment of patients with odontoid process fractures is based on the type of the fracture, patient's health status, age, association with neurologic deficits, and personal preference of the surgeon. Relative ind…
Experience in a Military Trauma Surgery Department with External Skeletal Fixation of Femur Fractures
1989
Our experience with external skeletal fixation of complex open and closed femoral fractures in 50 conventional trauma victims is presented. Different external fixator systems were primarily used in 26 patients and secondarily in 24 patients. The authors feel that early definitive femoral fracture care in civilian and military trauma victims employing unilateral external monofixation, which avoids casts, and allows improved wound management and early mobilization of the multitrauma patient, has decreased the complication rate commonly associated with internal fixation of open femoral fractures.
Cardiac complications after laparoscopic large hiatal hernia repair. Is it related with staple fixation of the mesh? -Report of three cases
2015
Introduction Laparoscopic Nissen operation with mesh reinforcement remains being the most popular operation for large hiatal hernia repair. Complications related to mesh placement have been widely described. Cardiac complications are rare, but have a fatal outcome if they are misdiagnosed. Presentation of cases We sought to outline our institutional experience of three patients who developed cardiac complications following a laparoscopic Nissen operation for large hiatal hernia repair. Discussion Laparoscopic hiatoplasty and Nissen fundoplication are safe and effective procedures for the hiatal hernia repair, but they are not exempt from complications. Fixation technique and material used m…
Radiation exposure to the hands and the thyroid of the surgeon during intramedullary nailing.
1998
Abstract During 41 procedures of intramedullary nailing of femoral and tibial fractures, the primary surgeon and the first assistant wore ring dosimeters on their dominant index fingers. While the average fluoroscopy time per procedure was 4.6 min, the average dose of radiation to the dominant hand of the primary surgeon was 1.27 mSv and 1.19 mSv to the first assistant. The dose limit for the extremities is 500 mSv per year, as recommended by the International Commission on Radiological Protection. Extrapolation of the mean dose of the primary surgeon and first assistent per procedure of 1.23 mSv leads to the result that the recommended dose limit of 500 mSv would only be exceeded if more t…
Prosthetic strap system for simplified ventral hernia repair. Its results in a porcine experimental model.
2010
Abstract: Introduction Aiming to achieve a simplified ventral hernia repair, a proprietary shaped mesh was experimentally tested in the porcine model. The mesh is structured with a large central body and radiating straps. The friction of the straps passing through the tissues are hypothesized to be adequate to maintain the mesh in place during tissue ingrowth, avoiding classic point fixation while ensuring a wide coverage of the abdomen. Methods The mesh, having 6 radial straps, was placed using a sublay preperitoneal technique in 4 pigs. All straps were passed laterally through the abdominal wall and exteriorized from the skin. The straps were trimmed at the level of the skin, allowing the…
A biomechanical evaluation of methods of distal humerus fracture fixation using locking compression plates versus conventional reconstruction plates.
2004
OBJECTIVES To examine the biomechanical behavior of 2 techniques of double-plate osteosynthesis for fractures of the adult distal humerus using conventional reconstruction plates and locking compression plates. DESIGN Basic science study. SETTING Experimental in vitro study. PATIENTS/PARTICIPANTS Forty fresh-frozen human distal humeri specimens. INTERVENTION Four matched groups with 10 humeri each, median age 74 years (46-95), were created using similar bone mineral density values. Two standard configurations of double-plate osteosynthesis (dorsal or 90 degrees configuration) with either conventional reconstruction plates or locking compression plates were studied for biomechanical properti…
Locked Plate Fixation and Intramedullary Nailing for Proximal Humerus Fractures: A Biomechanical Evaluation
2005
Background Internal fixation of proximal humeral fractures is associated with a considerable secondary malalignment rate. Fixed-angle implants have been suggested to increase the stability of fixation. Methods The biomechanical properties of four different implants were tested. These included an internal fixator with semi-elastic properties (reference), the Synthes T-plate, a locked plate with rigid properties and a spiral blade locked intramedullary nail (PHN). These implants were assessed in twenty-four osteotomized pairs of human cadaveric humeri. Specimens were subjected to two-hundred cycles of axial loading and torque followed by load to failure. Results The PHN had greater axial stif…
Posterior Wall Fractures of the Acetabulum: Characteristics, Management, Prognosis
2001
A consecutive series of 60 fractures of the posterior wall of the acetabulum, treated operatively in a Level I Trauma center, is reviewed retrospectively. Characteristics of the lesion, type of treatment, early and late postoperative complications and two-year functional results were recorded. In 27 patients (45%), additional damage to the cartilage of the acetabular cavity such as subchondral impaction, free articular fragments or separation of the posterior wall into several pieces was present. Seven patients (11.6%) showed preoperative neurological deficit. All fractures were treated with open reduction and internal fixation through a Kocher-Langenbeck approach. Secondary nerve damage wa…
Surgical nuances on the treatment of giant dumbbell cervical spine schwannomas: description of a challenging case and review of the literature
2016
We report a case of a giant intra and extradural cervical schwannoma in a patient affected by a severe myelo-radiculopathy. Clinical features, diagnosis and the issues concerning the surgical management of this benign tumor are discussed. We also review similar cases previously reported in the literature. A 50-year old caucasian woman was complaining of a 1 year of neck pain and worsening motor impairment in all four limbs causing the inability to walk. Neuroradiological assessment revealed a suspected schwannoma involving the nerve roots from C3 to C5, compressing and deviating the spinal cord. The vertebral artery was also encased within the lesion, but still patent. A posterior cervical …
Acetabulumfrakturen im Alter
2002
Acetabular fractures in elderly patients are rare injuries, but their incidence is increasing. Poor bone quality due to osteoporosis and an increased operative risk due to concomitant disease are factors complicating surgical therapy. Literature does not provide generally accepted treatment protocols. In a 4-year period, 27 patients who were 65 years or older and who had an acute displaced fracture of the acetabulum were admitted to our department. Four minimally displaced and stable fractures were managed conservatively. Internal fixation was performed in 16 cases. According to the Merle d'Aubigne score, in 15 out of 18 surviving patients excellent or good results were found. Treatment str…
