[Input of the start on the result of a special interdisciplinary rehabilitation program for work-related injuries of the hand].

Purpose: The objective of this study was to evaluate the outcome of a special interdisciplinary hand therapy program depending on the time interval between trauma and rehabilitation.

Patients And Methods: With use of self-assessed scores (Disability of the Arm, Shoulder and Hand Score [DASH-Score], European Quality of Life 5 Dimensions [EQ-5D]) and objective functional parameters (TAM = Total Active Motion for finger injuries, ROM = Range of Motion for wrist injuries, grip strength) the outcome of 76 patients with injuries of the fingers, wrist or a complex regional pain syndrome (CRPS) was analysed at the begin and end of an inpatient rehabilitation and at a follow-up examination after 12 to 16 weeks. The patients were divided into groups with an early (< 120 days after trauma) or late beginning of their rehabilitation.

ACTION trial: a prospective study on diagnostic Accuracy of 4D CT for diagnosing Instable ScaphOlunate DissociatioN.

Background: Early detection of scapholunate ligament (SLL) tears is essential after minor and major trauma to the wrist. The differentiation between stable and instable injuries determines therapeutic measures which aim to prevent osteoarthritis. Arthroscopy has since been the diagnostic gold standard in suspected SLL tears because non-invasive methods have failed to exclude instable injuries reliably.

Background: Alloarthroplasty of the proximal interphalangeal joint is indicated for patients with osteoarthritis, an inflammatory disease of the joint. According to the current literature, implants made of silicone are not inferior to newer implants and the complications are well known. Therefore, focus should be shifted to the operative approach to improve the results.

Ulnocarpal impaction syndrome: treatment with a transverse ulnar shortening osteotomy from an ulnodorsal approach.

Introduction: Ulnocarpal impaction syndrome is a common cause of chronic ulnar-sided wrist pain. The distal ulnar shortening osteotomy addresses the often present positive ulnar variance and therefore relieves the excessive load on the ulnocarpal joint. In the present study, the results of a technique that uses an ulnodorsal approach with a compression device and a transverse osteotomy are presented and compared to other techniques.

Comparison of clinical results after pisiformectomy in patients with rheumatic versus posttraumatic osteoarthritis.

Pisotriquetral osteoarthritis is important to consider in the differential diagnosis of chronic ulnar-sided wrist pain. It can develop following traumatic injury to the pisiform or in rheumatic diseases, such as rheumatoid arthritis or psoriatic arthritis. It has been shown that pisiformectomy can relieve symptoms in cases that have not responded to nonoperative treatment, and the excision does not compromise the function or strength of the wrist.

Results of Mannerfelt wrist arthrodesis for rheumatoid arthritis in relation to the position of the fused wrist.

Purpose: The wrist is involved early in rheumatoid arthritis and is often severely affected. A stable wrist is crucial to good hand function, which often necessitates a fusion. One of the most commonly used techniques in rheumatoid patients is the Mannerfelt arthrodesis.

Nodular giant cell tumour of the tendon sheath of the hand: analysis of eighty-four cases: diagnostic decisions and outcome.

Introduction: The giant cell tumour of the tendon sheath (GCTTS) of the hand is a benign tumour of unknown origin. The clinical diagnosis is supported by preoperative imaging. But the ideal imaging methods necessary for the diagnosis, preoperative planning and total tumour resection are still debated.

Postoperative monitoring of free vascularized bone grafts in reconstruction of bone defects.

Vascularized bone transfer is increasingly recognized as a very useful and versatile technique for reconstructing large bone defects. It is especially indicated in patients with challenging conditions, such as nonunions, postoncologic resections, severe trauma, and congenital defects. With increasing experience of reconstructive surgeons, improved microsurgical techniques, and more enhanced flaps, the failure rate of free flaps has been reduced in the last decades.
