Task design, psycho-social work climate and upper extremity pain disorders--effects of an organisational redesign on manual repetitive assembly jobs.

A company redesign was carried out to improve production efficiency and minimise the prevalence of work-related musculoskeletal disorders and sick leave. The redesign was evaluated on the basis of studies of assembly workers before (17 workers) and after (12 workers) the redesign. The redesign resulted in more varied, less repetitive, and more autonomous assembly jobs. The psycho-social work climate was both improved and impaired. A medical examination showed that eight of 17 workers before and nine of 12 workers after the redesign suffered from upper extremity pain disorders. Neither the production goals nor the goals of the redesign were fulfilled. Our conclusion was that the increased task variation and impaired psycho-social work climate, combined with a lack of skill and competence, actually increased the physical stress, risk for disorders and difficulties in fulfilling the production goals.

Continuous brachial plexus block for replantation in the upper extremity.

For replantation surgery, continuous brachial plexus block was employed using supraclavicular or axillary approach. Of a total of fifty blocks, forty-seven (94%) gave adequate surgical analgesia throughout the operations. No serious complication appeared in this series. Pneumothorax was detected in one supraclavicular block, but no surgical drainage was required. One patient had paraesthesia in the blocked arm, but it subsided within a month. No toxic reaction was recognised in spite of high dose of anaesthetic agents. Thus continuous brachial plexus block has been ascertained to be safe, reliable, and useful for the replantation and other prolonged operations in the upper extremity.

Management of upper extremity cumulative trauma disorders.

1. Elements critical to a successful medical management program include cumulative trauma disorder (CTD) surveillance, conditioning and rehabilitation programs, and familiarity with OSHA recordkeeping requirements, in addition to recognition, evaluation, and treatment. 2. Occupational health care providers (HCPs) can identify high risk departments, production lines, or jobs through the passive and/or active surveillance systems. 3. The HCP should perform a CTD evaluation of employees assigned to jobs with known ergonomic hazards or areas found to have CTD problems by the surveillance system. These evaluations should consist of a medical and occupational history, and a physical examination of the upper extremities. 4. The treatment algorithm emphasizes that a) symptomatic employees need follow up to determine the effectiveness of the prescribed treatments, b) employees with severe symptoms, positive physical findings, or disorders resistant to treatment need to be referred to a physician for further evaluation, and c) conservative therapy deserves an adequate trial before surgical intervention is contemplated.

Technetium-99m red blood cell venography in upper extremity deep venous thrombosis.

The efficacy of Tc-99m RBC venography has been demonstrated with respect to the study of lower extremity deep venous thrombosis. A case is presented where Tc-99m RBC venography was used to study the upper as well as lower extremities in a patient with upper extremity deep venous thrombosis (DVT) who was found to have pulmonary embolism.

[Timing of soft tissue reconstruction in severe crush injury of the upper extremity].

Complex injuries of the distal forearm and the hand by industrial machines often require extensive reconstructive procedures. Crush injuries with soft tissue damage extending over the limits of visible injury require a special approach. Large soft tissue defects often have to be covered by extensive flap procedures. The optimum point of time for plastic reconstruction is an essential question and represents a controversial issue in the literature. To be able to compare different patient cohorts in the future, we classify crush injuries into five clinically relevant categories. In the course of this review article, three different cases of severe crush injuries of the upper extremity are representatively discussed. Two patients were reconstructed in a secondary procedure, one patient in the acute phase. Definite coverage of soft tissue defects in severe crush injuries should be performed secondarily after 5-7 days since the extent of damage in this special form of trauma can often only be judged after a few days and the reconstruction of bones, vessels and tendons is completed.
