The treatment of intra-articular calcaneus fractures with severe soft tissue damage with a hinged external fixator or internal stabilization: long-term results.

We developed a hinged external fixator for the treatment of dislocated intra-articular calcaneus fractures with severe soft tissue damage. The external fixation was performed with a known external fixator system. The screw insertion points were biomechanically tested by defining a virtual rotation axis through the center of the talus to allow early active motion in the ankle joint.

Hemiarthroplasty of the shoulder after four-part fracture of the humeral head: a long-term analysis of 34 cases.

Objective: To assess the treatment outcomes of patients with four-part fracture of the humeral head after primary and secondary hemiarthroplasty.

Patients: Retrospective long-term analysis of 46 patients from 1996 to 2002 of patients with 47 four-part fractures of humeral head. Patients with malignant disease were excluded.

Dynamic and functional gait analysis of severely displaced intra-articular calcaneus fractures treated with a hinged external fixator or internal stabilization.

The purpose of this article was to assess functional gait outcome. Fifty-five patients with severely displaced intra-articular calcaneus fractures and soft tissue damage were evaluated prospectively with computerized dynamic pedography and a clinical scoring scale. The treatment protocol assigned 30 patients to open reduction and internal fixation (ORIF) and 25 to closed reduction and stabilization with a biomechanically tested hinged external fixator.

Value of fat-suppressed PD-weighted TSE-sequences for detection of anterior and posterior cruciate ligament lesions--comparison to arthroscopy.

Objective: To evaluate fat-suppressed (FS) proton-density-weighted (PDw) turbo spin-echo (TSE) magnetic resonance imaging for the detection of anterior and posterior cruciate ligament lesions in comparison to arthroscopy.

Materials And Methods: In a prospective study 31 knee joints were imaged on a 1.5T MR scanner (Vision, Siemens, Erlangen) prior to arthroscopy using following sequences: (a) sagittal FS-PDw/T2w TSE (TR/TE: 4009/15/105 ms); (b) sagittal PDw/T2w TSE (TR/TE:3800/15/105 ms).

Experimental and clinical evaluation of acromioclavicular joint structures with new scan orientations in MRI.

The objective of the study was to evaluate MRI for visualization of acromioclavicular (ac) joint structures in cadaveric shoulders, asymptomatic volunteers and symptomatic patients with trauma of the ac-joint. Three cadaveric shoulders were examined to find adequate planes and sequences for MRI. Afterwards, MR images were correlated to corresponding anatomical sections.
