Internal Fixation in Postpartum Symphysis Pubis Rupture: Report of Three Cases
1997
We present three patients with postpartum symphysis pubis rupture whose severe complaints persisted after conservative treatment. All three ruptures were stabilized with open reduction and internal fixation. There were no postoperative problems, and implants were removed after a mean period of six months. Patients were free of complaints after implant removal. In select cases, operative treatment of postpartum symphysiolysis may be indicated.
Clinical pathways for fragility fractures of the pelvic ring: personal experience and review of the literature
2014
AbstractFragility fractures of the pelvic ring (FFP) are increasing in frequency and require challenging treatment. A new comprehensive classification considers both fracture morphology and degree of instability. The classification system also provides recommendations for type and invasiveness of treatment. In this article, a literature review of treatment alternatives is presented and compared with our own experiences. Whereas FFP Type I lesions can be treated conservatively, FFP Types III and IV require surgical treatment. For FFP Type II lessions, percutaneous fixation techniques should be considered after a trial of conservative treatment. FFP Type III lesions need open reduction and in…
Osteosynthesetechniken bei proximalen Humerusfrakturen
2001
Proximale Humerusfrakturen sind haufige Verletzungen. Die Frage der optimalen osteosynthetischen Behandlung instabiler und dislozierter 2- bis 4-Segmentfrakturen ist nach wie vor nicht einhellig geklart. Die operative Therapie befindet sich in der Konfliktsituation zwischen der Forderung einer anatomischen Reposition und stabilen Frakturretention auf der einen Seite und der Notwendigkeit einer maximalen intraoperativen Schonung der periglenohumeralen Weichteilstrukturen und Blutversorgung des Oberarmkopfs, mit dem Ziel das iatrogene Risiko der avascularen Kopfnekrose zu minimieren, andererseits. Wahrend Minimalosteosynthesen, bei denen die Reposition indirekt oder percutan erfolgt, Vorteile…
Randomized, Double-Blind, Clinically Controlled Trial of Intranasal Calcitonin Treatment in Patients with Hip Fracture
2002
The objective of this study was to evaluate the short-term outcome of intranasal calcitonin treatment of elderly hip fracture patients on pain, bone loss, functional recovery, and length of hospital stay. In addition, we wanted to compare the effect of calcitonin with placebo on fusion of hip fractures treated with internal fixation using a screw or a nail. In a randomized, double-blind, clinically controlled trial, 260 independently living patients (aged 65 years or older) with acute hip fracture were randomly assigned to intranasal calcitonin 200 IU daily for 3 months or matching placebo nasal spray. Analyses were completed on an intention-to-treat basis. Three months after the operation,…
Paradoxical embolism after a femoral fracture
1998
The foramen ovale is anatomically open in 25 % of individuals, but functionally closed by the higher pressure in the left antrum. Right-to-left shunt and subsequent paradoxical embolism may occur when pressure in the left antrum rises, for example, as a result of pulmonary embolism. In the present case we demonstrate a patient who presented 20 days after osteosynthetic treatment of a femoral fracture with word-finding deficits. Cerebral MRT revealed a fresh ischemic insult. Duplex ultrasound of the legs showed a fresh thrombosis of the superficial femoral vein and scintigraphy of the lungs detected pulmonary embolism. Transesophageal contrast echocardiography trapped a hemodynamically spont…
The efficiency of lead thyroid shield in trauma surgery
1997
Die Strahlenbelastung der Operateure bei unfallchirurgischen Eingriffen hat in den letzten Jahren durch den Trend zu biologischen Osteosyntheseverfahren, insbesondere der Marknagelung, zugenommen, da geschlossene Reposition und distale Verriegelung radiologisch kontrolliert werden. Wir wollten jetzt uberprufen, welchen Einflus der Schilddrusenbleischutz auf die Strahlenbelastung der Operateure bei operativen Eingriffen an den unteren Extremitaten hat. Mit Hilfe eines Unterschenkelphantoms wurden unterschiedliche intraoperative Durchleuchtungssituationen simuliert und die Strahlenbelastung der Schilddruse mit und ohne Bleischutz des Operateurs uber ein Dosismesgerat (Szintomat) festgestellt.…
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 …
New intramedullary locking nail for olecranon fracture fixation--an in vitro biomechanical comparison with tension band wiring.
2010
The aim of this study was to determine the difference in displacement of a newly designed intramedullary olecranon fracture fixation device compared with multifilament tension band wiring after 4 cycles and 300 cycles of dynamic continuous loading.In eight pairs of fresh-frozen cadaver ulnae, oblique olecranon fractures were created and stabilized using either newly designed intramedullary olecranon nail or multifilament tension band wiring. The specimens were then subjected to continuous dynamic loading (from 25 N to 200 N) using matched pairs of cadaveric upper extremities. The Wilcoxon test was used to determine statistical differences of the displacement in the fracture gap.After 4 cycl…
Volar Fixed-Angle Plating of Distal Radius Fractures
2011
The purpose of this biomechanical study was to determine whether a multidirectional fixed-angle plate with locking screws or with locking pegs in the distal fragment would optimize fixation of Orthopaedic Trauma Association (OTA) type A3 distal radius fractures.Eight pairs of fresh-frozen human distal radii were used. Extra-articular distal radius fractures were created and stabilized with a multidirectional volar fixed-angle plate. The radii were randomized into 2 matched-paired groups. The distal fragment in Group I was stabilized with 7 locking screws. The distal fragment in Group II was fixed with 7 locking pegs. The proximal fragment in both groups was fixed with 3 screws. The specimen…
Dynamic biomechanical analysis of different olecranon fracture fixation devices--tension band wiring versus two intramedullary nail systems: an in-vi…
2007
Abstract Background. The aim of this study was to develop a test-setup with continuous angle alteration to imitate joint motion for the evaluation of 3 different olecranon fracture fixation devices. Methods. Twenty-one fresh cadaver upper extremities underwent olecranon fracture by the means of transverse osteotomy and received 3 different fixation systems. Group 1: Tension band wiring according to Weber. Group 2: XS-nail with 9 holes, all locked with 2 mm threaded K-wires. Group 3: Olecranon Nailing System with 90 mm length, locked with 2.7 mm screws, a variable angle locking hole for the proximal fragment and a proximal locking end cap. The servo-pneumatical test stand worked with a rotat…
