Problem: Fractures of the distal humerus are difficult to treat. In elderly patients, diminished bone mineral quality and increased trauma-associated joint destruction may make stable joint reconstruction even more problematic. Furthermore, comorbidities and poor tolerance of joint immobilization might be additional factors which influence elbow function(More)
During a 5.5-year period, we treated 64 patients with acute acromioclavicular separations by surgical reconstruction. According to the classification of Rockwood and Matsen, 54 patients had type III lesions, 1 patient had a type IV lesion, and 9 patients had type V lesions. Both the coracoclavicular ligaments and the ligaments of the acromioclavicular joint(More)
To determine the outcome after indirect reduction and buttress plate fixation of displaced and unstable proximal humeral fractures, we retrospectively evaluated 98 patients, an average of 34 months (range 24-72 months) after fracture fixation. The patients were reviewed and results were evaluated clinically according to the Neer, UCLA and Constant score. A(More)
BACKGROUND Radial head arthroplasty is considered the treatment of choice for unreconstructable radial head fractures in the acute fracture situation. Although short-term results in the current literature are promising, replacement of the radial head remains controversial as long-term results are still missing. We report our 8.8-year results after treatment(More)
The posterior wall fracture – the most frequent acetabular lesion – is often regarded as the simplest acetabular fracture. In fact, a large variety of complex articular lesions is subsumed under this fracture type. A consecutive series of 60 posterior wall fractures is reviewed retrospectively. Lesions characteristics, treatment method, early and late(More)
Although proximal humeral fractures are common injuries, there is no generally accepted strategy as to how unstable and displaced two- to four-part fractures should be managed. Surgical therapy is in a conflicting situation between the requirement for anatomical fracture reduction and stable fixation, on the one hand, and the necesscity for minimal(More)
BACKGROUND In contrast to arterial occlusive disease, data on long-term outcomes after vein grafts in limb trauma with arterial injury are sparse. PATIENTS From 1991 through 2001, 22 trauma victims received 23 interposition vein grafts performed by an interdisciplinary team of trauma and vascular surgeons. Indications included both blunt and penetrating(More)
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),(More)
OBJECTIVE To analyze injury pattern, surgical therapy, radiologic results, and functional outcome in unstable B-type and C-type pelvic ring fractures. DESIGN Retrospective study. SETTING Level I University Trauma Center. PATIENTS Two-hundred-twenty-two consecutive patients, admitted during a nine-year period with unstable B-type (n = 100) and C-type(More)
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(More)
