About 70 to 80 % of these fractures are in the middle third of the clavicle (1,5). Fractures of the clavicle have been traditionally treated nonoperatively. Functional and cosmetic results frequently fall short of the patient’s and the surgeon’s expectations. ! is review of up-to-date literature might help for re-evaluation of well accepted concepts concerning the treatment of mid-shaft clavicular fractures.

Methods: In 30 cadavers preserved according to Thiel's method and aged between 61 and 76 years (mean 64 years), retrograde femoral nailing was performed in both legs (n = 60) through a transligamentous approach using a DFN (distal femoral nail, Mathys-Synthes®). The procedure was radiologically controlled by an image intensifier. Subsequently, the knee joints (n = 60) were dissected and the entry point of the nail was evaluated anatomically and morphometrically. Results: Depending on the size of the joint, 7-15% of the patello-femoral articular surface (Facies articularis patellaris femoris) were destroyed by the implantation of the DFN. In none of the specimens, lesions of the PCL-origin were observed. Conclusion: Retrograde femoral nailing is a safe technique if lesions of the PCL are considered. Destruction of retropatellar articular cartilage due to the nail's diameter is relatively higher in small joints. However, the region of destruction is placed in the distal part of the patello-femoral joint, which is not exposed to extended loading during the gait circle.

In many patients, conservative treatment has shown poor functional results, despite satisfactory radiologic findings. This is due to a remarkably high number of concomitant carpal lesions occurring together with distal intraarticular radius fractures. Using wrist arthroscopy in the acute management of these fractures, the intraarticular fracture pattern can be exactly evaluated and concomitant carpal lesions like tears of the intrinsic ligaments of the proximal carpal row, lesions of the triangular fibrocartilage complex and free intraarticular bodies can be diagnosed and treated at the same sitting.

With these complications in mind, the authors discuss fractures of the talus, calcaneus, lesser tarsal bones, Lisfranc's joint, metarsals, and phalanges. Dislocation of metatarsophalangeal or interphalangeal joints is also discussed.

One hundred cadaver specimens were assessed and the widths of the triceps tendon and the olecranon and the expansion of the LCR were determined. The width of the tendon ranged between 1.9 and 4.2 cm (mean: 2.81) and the width of the olecranon between 1.8-3.8 cm (mean: 2.5). In 65 of the 100 specimens, the width of the tendon was greater than that of the olecranon. The fibers on the medial side inserted exactly on the medial aspect of the olecranon, whereas on the lateral aspect the fibers left the olecranon to reach the posterior border of the ulna. In 28 specimens the olecranon was wider than the tendon of the triceps, and in seven extremities the tendon occupied exactly the whole area of the olecranon. The LCR measured 2.3-7.2 cm (mean: 4.04 cm). By preserving parts of the trice...

The hypothenar region was studied with sonography in 20 healthy volunteers using 5-12-MHz linear-array transducers. The assessment included dynamic testing. All hypothenar muscles could be identified in all subjects and their courses followed entirely. In addition, their function could be assessed by scanning during active and passive movements. Knowledge of the normal sonographic anatomy of the hypothenar region is essential for evaluation of pathologic conditions.
