Fragility Fractures of the Pelvis.
2017
Fragility fractures of the pelvic ring (FFP) show an increasing frequency. Trauma mechanism, fracture morphology and degree of instability are different from those in high-energy pelvic ring lesions. Little is known about the optimal treatment strategy. A new comprehensive classification system with four categories of increasing instability is presented. It is connected with recommendations for type and invasiveness of treatment. FFP Type I are anterior instabilities only and can be treated conservatively. FFP Type II are non-displaced posterior lesions which can be treated conservatively or with percutaneous fixation. FFP Type III lesions are unilateral displaced posterior lesions which re…
Is there a role for percutaneous pelvic and acetabular reconstruction?
2007
The primary goal in the treatment of pelvic fractures is the restoration of haemodynamic stability. The secondary goal is the reconstruction of stability and symmetry of the pelvic ring. Percutaneous reconstruction can only be accepted if these goals are met. The type of definitive surgery is dependent of the degree of instability of the anterior and posterior pelvic ring. Retrograde transpubic screw fixation of pubic rami fractures is a good alternative to external fixation or plate and screw osteosynthesis. The technique of screw placement and image intensifier control is explained. Internal fixation of pure sacroiliac dislocations, fracture-dislocations of the sacroiliac joint and sacral…
Secondary Osseous Integration of Cementless Unicompartmental Knee Arthroplasty After Internal Fixation of a Felix Type IIIB Fracture
2021
Case A 76-year-old man presented with periprosthetic tibial plateau fracture (TPF), with a completely loosened tibial component 3 weeks after cementless unicompartmental knee arthroplasty (UKA). Internal fixation by buttress plating was performed, and the tibial component was retained and left in situ primarily as a spacer. Revision was planned after fracture consolidation, but at 3 months, the patient was able to walk without support, without pain, and with full range of motion. At 1 year, he is free of complaints. The initial loosened tibial component reintegrated. Conclusion Internal fixation combined with preserving the loosened tibial component may be a treatment option for TPF involvi…
Osteosynthese am proximalen Humerus mittels winkelstabiler Platte oder Doppelplatte: eine vergleichende biomechanische Untersuchung / Angle-fixed pla…
2008
Internal fixation of fractures of the proximal humerus needs a high stability of fixation to avoid secondary loss of fixation. This is especially important in osteoporotic bone. In an experimental study, the biomechanical properties of the angle-fixed Philos plate (internal fixator) and a double-plate osteosynthesis using two one-third tubular plates were assessed. The fracture model was an unstable three-part fracture (AO type B2). Eight pairs of human cadaveric humeri were submitted to axial load and torque. In the first part of the study, it was assessed to which degree the original stiffness of the humeri could be restored after the osteotomy by the osteosynthesis procedure. Subsequentl…
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.
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…
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…
Internal Fixation of Proximal Humeral Fractures: Current Concepts
2003
Fractures of the proximal humerus are an increasingly common type of injury. Mainly elderly patients with osteoporotic bone are affected. Whereas non-displaced and stable fractures are managed successfully with conservative treatment, there is no general agreement on the surgical strategy for displaced and unstable two- to four-part fractures. The clinical outcome is influenced by the fracture type and concomitant injury to the rotator cuff. Extensive surgical manipulation of the soft tissues, non-anatomic and/or unstable fixation as well as technical errors are important contributing factors to poor clinical results. Goals of surgical treatment are to restore anatomy, to achieve fixation t…
Biomechanical evaluation of a new treatment method for distal tibia fractures
2015
Distal tibial fractures are often the result of high-energy impacts combined with excessive soft tissue injury. Treatment options include either open reduction and internal fixation usually as a mi...
