The Danish Sarcoma Database.

Aim: The aim of the database is to gather information about sarcomas treated in Denmark in order to continuously monitor and improve the quality of sarcoma treatment in a local, a national, and an international perspective.

Study Population: Patients in Denmark diagnosed with a sarcoma, both skeletal and ekstraskeletal, are to be registered since 2009.

Main Variables: The database contains information about appearance of symptoms; date of receiving referral to a sarcoma center; date of first visit; whether surgery has been performed elsewhere before referral, diagnosis, and treatment; tumor characteristics such as location, size, malignancy grade, and growth pattern; details on treatment (kind of surgery, amount of radiation therapy, type and duration of chemotherapy); complications of treatment; local recurrence and metastases; and comorbidity.

Complications and survival after surgical treatment of 214 metastatic lesions of the humerus.

Background: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus.

Materials And Methods: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus.

[Malignant tumours of the hand].

Malignant tumours of the hand are rare and are often misdiagnosed. A painful swelling of the hand or digits are often diagnosed with an infection, benign tumours such as ganglion cysts, or arthritis. Wounds that do not heal despite adequate treatment should be biopsied to rule out malignancy.

[Elbow arthroplasty].

Each year, about 80 elbow arthroplasties are performed in Denmark. Approximately two thirds are done due to rheumatoid arthritis, the others due to comminuted fractures of the elbow, especially in elderly patients. The prosthesis is fixed with or without bone cement, and there are two different types of elbow prostheses: linked, in which the humerus and ulna are connected by a sloppy hinge, and non-linked, in which stability is dependent on the soft tissues of the elbow.

[Shoulder arthroplasty].

Every year, almost 500 shoulder arthroplasties are performed in Denmark. About two-thirds are done due to fractures of the proximal humerus. Other common indications are rheumatoid arthritis and primary or secondary arthrosis.

[Posttraumatic osteolysis of the distal clavicle].

Posttraumatic osteolysis of the distal clavicle (ODC) is a very rare condition that occurs after acute injury or repetitive microtrauma of the shoulder and which is characterized by persistent shoulder pain, restricted shoulder motion, and progressive osteolytic changes at the outer end of the clavicle. A case of posttraumatic osteolysis of the distal clavicleis presented and the aetiology, diagnosis and treatment are discussed.

Bone bruise in the acutely injured knee.

We used MRI to study the lesions in a consecutive group of 64 patients with an acute trauma of the knee and normal plain radiography during the winter season. Bone bruise was present in 35 of the patients, and these were referred to subsequent MRI 4 and 12 months later. After 4 months bone bruise was still present in 69% of the patients and after 12 months in 12%.
