The von Willebrand's Disease affects about 1-3% of the population and it is undiagnosed in most people. Originally described by the Finish physician Erik von Willebrand in 1926 this disorder is associated with mucous membrane bleeding including epistaxis, hypermenorhoea and excessive bleeding from surgery and dental procedures. In von Willebrands disease the patients have a quantitative or qualitative abnormality in the von Willebrand Factor (vWF) which has two major functions: it serves by bridging between platelets and injury site in the blood vessel wall, and it circulates as a complex with factor VIII, protecting it from rapid degradation. ⋯ Until now no recommendations in the orthopaedic literature have been found regarding diagnosis and treatment of vWS patients. Based on the experience with 43 orthopaedic patients presenting vWD over the last 15 years a contemporary guideline for the successful perioperative management of vWD in orthopaedic surgery is presented. In a close collaboration between the orthopaedic surgeon and the specialized haemostaseologist every invasive procedure in patients with vWD can be undertaken without the risk of excessive bleeding.

In the orthopedic department of the University Hospital Homburg/Saar, we use since 1993 a computer-based system for clinics organisation and documentation of operations. Hardware consists of DOS/Windows PC's in a Novell-network. Our software is a combination of database-system for managing patient-data and a special coding program for ICD and IKPM-digits. ⋯ Until now, we used the system for 31,500 patients and 8500 operations. A flexible software can meet the requirements both of the surgeons and administration. Moreover, in the University hospital Homburg/Saar, the different departments are linked by an Intranet with connection to other scientific networks and the Internet.

There are no clear guidelines on the treatment of relapsed clubfoot, which is a relatively frequent and difficult problem in paediatric orthopaedics. Numerous operative interventions are mentioned in the literature as suitable for correction of a residual deformity of the food. There are numerous soft tissue procedures (release operations, tendon extensions, tendon transfers and redressement by means of a fixateur externe) and osseous interventions (osteotomies, arthrodeses) that can be carried out in isolation or in combination. ⋯ It the calcaneus is found to have a short posterior part this osteotomy is modified so that instead of taking the form of a wedge osteotomy with lateral closing it is followed by a lateral displacement. In this way it is possible to prevent making the already short posterior calcaneus even shorter. Both the combined midfoot osteotomy and the calcaneal osteotomy after Dwyer can be performed alone or in combination with each other or with different operative interventions.

Review
[Management of old neglected posttraumatic acromioclavicular joint instability and arthrosis].
Resection arthroplasty of the AC joint was performed in 42 cases of osteoarthrosis and residual instability of traumatic origin including 26 shoulders with horizontal instability of more than half of the width of the clavicula and lesions of the deltotrapezoid fascial complex (Rockwood type II: 7; type III: 9; type IV: 17; type V: 9). 23 cases were treated with a sole Weaver-Dunn procedure. 26 cases with horizontal instability and lesions of the deltotrapezoid fascia (Rockwood IV and V type) were treated in 7 cases with the standard Weaver-Dunn procedure and in 19 cases with a modified Weaver-Dunn procedure in combination with a coracoclavicular (3 x 1) and acromio-clavicular (1 x 1) 1 mm PDS string augmentation and double breasting fascioplasty of the deltotrapezoid complex. ⋯ Cases with horizontal instability (type Rockwood IV and V) seem to be over-represented among patients with failed conservative treatment. Resection arthroplasty with ligament transposition after Weaver/Dunn gives excellent results in posttraumatic osteoarthrosis with mainly vertical and moderate horizontal instability. In cases with advanced horizontal instability after Rockwood IV and V injuries, almost equal results can be reached by an additional coracoclavicular and acriomioclavicular PDS augmentation with deltotapezoid fascioplasty.
