[Diagnostic value of preopratively performed MRI regarding lesions of the scapholunate ligament in clinical routine].
The purpose of this retrospective study was to examine the sensitivity and specificity of preoperatively performed MRI of the wrist in identifying tears of the scapholunate ligament. Additionally, these findings were then compared with findings from a subsequently performed -arthroscopy of the wrist. ⋯ The comparison of MRI vs. arthroscopic sensitivity and specificity in the detection of scapholunate tears on a sufficiently large group of patients showed MRI to be a reliable method in excluding scapholunate ligament tears. Outside of clinical study conditions, however, it was found to be an unsuitable method in identifying and classifying scapholunate ligament tears. The high MRI sensitivity found by other studies could not be confirmed in our study.

Hemi-hamate autograft arthroplasty for acute and chronic PIP joint fracture dislocations.
Treatment of fracture dislocations of the PIP joint represents a hand surgical challenge. In hemi-hamate arthroplasty, the palmar joint surface is reconstructed using an osteochondral graft from the hamate and the immediate stability permits early movement. ⋯ Hemi-hamate autograft arthroplasty represents an effective procedure to address severe PIP joint fracture dislocations. It restores the comminuted articular surface in chronic injuries and in the acute injury it is a challenging but valuable alternative to extension block splinting. However, donor site morbidity and revision surgery have to be taken into account.
