[Hamulus fracture: a frequently unrecognized injury. Presentation of diagnosis and therapy based on two case reports].

Fractures of the hook of the hamate are rare injuries of the hand. They are caused by direct trauma to the palm, however there are some cases without history of trauma. While physical examination is often suspicious of fracture, standard X-ray films can fail to demonstrate the fracture. Bone scans show an increased uptake in the ulnar region of the wrist. The carpal tunnel view or computed tomography confirm the diagnosis. Operative treatment is recommended. Simple excision of the hook, bone grafting or internal fixation are possible procedures. The diagnostic problems are demonstrated in two case reports.

[Computerized tomography of the hand with high resolution technique].

The results of 175 high-resolution computed tomography (CT) scans of the hand and wrist are analysed and compared to the results of conventional radiographs. Advantages of the procedure can be demonstrated when assessing pathological changes within the complex three-dimensional structure of the hand and wrist, and in the analysis of articular surfaces. In some cases, fractures and dislocations of the distal radioulnar joint and the carpal bones were missed in conventional radiographs. In cases of scaphoid fracture and nonunion, CT scans give valuable additional information surpassing the possibilities of conventional radiographs. For instance, bone healing after bone grafting can be better evaluated with a CT scan. Furthermore, preoperative planning is simplified, when tumors and cysts of the carpal bones can be located precisely using computed tomography.

[Distal radio-ulnar arthrodesis and Kapandji ulna segment resection in treatment of limited forearm rotation].

Between 1986 and 1990 distal radioulnar arthrodesis with segment resection of the distal ulna (Sauvé-Kapandji Operation) was performed in 31 patients with posttraumatic changes of the distal radioulnar joint; 26 patients could be examined after 10 to 44 months. At the time of examination, all patients had bony fusion between distal radius and ulna; forearm rotation improved by 60.5%, 55% of the patients had significant pain relief. Grip strength also improved postoperatively, though never reaching values of the healthy hand. Two patients developed a bony regeneration, which was successfully reoperated upon in one case, 81% of the patients reported an improved wrist function.
