Attritional flexor tendon rupture due to a scaphoid non union imitating an anterior interosseous nerve syndrome: a case report.

A case is presented of acute loss of function of flexor pollicis longus and profundus tendon to the index finger. Although the aetiology was obscure, the acute onset suggested a mechanical cause rather than a nerve compression disorder such as anterior interosseous nerve palsy. X-rays showed an ununited scaphoid fracture related to an injury many years previously. Surgical exploration revealed attritional rupture of flexor pollicis longus and partial division of profundus tendon to index finger by a spicule of ununited scaphoid which had eroded through the volar capsule. Removal of the spicule and tenodesis of flexor pollicis longus gave a good long term result.

Psychological assessment in general orthopaedic practice.

The importance of psychologic distress and illness behavior is well recognized in low-back pain but has rarely been studied in other orthopedic conditions. Psychologic and clinical assessment of 100 patients undergoing elective surgery for minor leg conditions or joint replacement for osteoarthritis or rheumatoid arthritis showed surprisingly little psychologic distress or illness behavior, particularly when compared with 235 patients with low-back pain. The most striking finding was that in low-back pain there was a close relation between psychologic disturbance and failed surgery, but the nonspinal patients showed a complete absence of such a relation. This type of psychologic assessment is neither necessary nor helpful in the routine management of most clearly defined, nonspinal, correctly managed orthopedic conditions.

Chronic low-back pain, psychologic distress, and illness behavior.

The authors have calculated the mathematic relationship between measured elements of illness behavior in chronic low-back pain. Objective physical impairment accounts for about one-half the total disability that also is affected by psychologic reactions. The most important psychologic disturbance in low-back pain is emotional distress, measured on questionnaires as increased bodily awareness and depression and presenting clinically as inappropriate descriptions of symptoms and inappropriate responses to physical examination. Simple methods for the assessment of distress and illness behavior in chronic low-back pain are developed and described.

Fine screen filtration of banked blood: effect on red cell survival.

Two fine screen mesh microfilters and the Baxter blood administration set commonly used in U.K. hospitals were compared for their effect on the red cell survival of transfused stored autologous blood in six healthy males. The effect of the filtered transfusions on pulmonary gas exchange and on blood coagulation was measured. No significant difference was found between either microfileter and the Baxter giving-set for the red cell survival of transfused blood. Pulmonary gas exchange and coagulation were unaffected by transfusion of one unit of whole blood. Post-transfusion bilirubin concentrations were significantly less with one of the microfilters compared with the Baxter giving-set, possibly because of trapping of effete red cells within the filter. An unsuspected finding was the effect of transfusion in increasing the peripheral blood neutrophil count.
