  • Article: Flexor carpi ulnaris tendon transfer to the split brachioradialis tendon to restore supination in paralytic forearms.
    G A Anderson, B P Thomas, S C R Pallapati
    [show abstract] [hide abstract]
    ABSTRACT: Inability to actively supinate the forearm makes common activities of daily living and certain vocational activities awkward or impossible to perform. A total of 11 patients with deficient supination of the arm underwent transfer of the tendon of flexor carpi ulnaris to the split tendon of brachioradialis with its bony insertion into the radial styloid left intact. Active supination beyond neutral rotation was a mean of 37.2 degrees (25 degrees to 49.5 degrees ) at a minimum follow-up of three years, representing a significant improvement (95% confidence interval 25 to 50, p < 0.001). Functional evaluation of the hand after this transfer showed excellent and good results in ten patients and fair in one. The split tendon of brachioradialis as an insertion for transfer of the flexor carpi ulnaris appears to provide adequate supination of the forearm without altering the available pronation and avoids the domination of wrist extension sometimes associated with transfers of the flexor carpi ulnaris to the radial extensors of the wrist.

  • Article: Carpal tunnel syndrome in Indian patients: use of modified questionnaires for assessment.
    [show abstract] [hide abstract]
    ABSTRACT: This study was conducted to assess the use of a modified carpal tunnel syndrome questionnaire (the Boston Carpal Tunnel Questionnaire, BCTQ) in an Indian patient population. Seventy-six Indian patients with carpal tunnel syndrome (CTS) were recruited to this prospective study. On a scale of one to five, the average score for the severity of symptoms was 2.09 (0.89). The average score for functional disability was 1.94 (0.74), which was lower than the average function score reported for Western CTS patients (Levine et al., 1993). The symptom severity and function disability scores were higher in patients with positive Tinel's sign and Phalen's test. The function disability score was moderately correlated with other clinical tests for CTS. The average modified BCTQ scores for Indian CTS patients was established through this study. This modified questionnaire might assist physicians in developing countries to assess disability from CTS, although socioeconomic and cultural differences will have to be taken into account when comparing assessments across different populations.

    Article: Arthrodesis of flail or partially flail wrists using a dynamic compression plate without bone grafting.
    G A Anderson, B P Thomas
    [show abstract] [hide abstract]
    ABSTRACT: Between June 1991 and May 1996 we carried out arthrodesis on 15 patients with flail or partially flail wrists using an AO/ASIF dynamic compression plate (DCP) without a bone graft. The wrist was approached through the second extensor compartment. The minimum follow-up was for 24 months with a mean of 34.2 months. All 15 wrists fused without major complications at a mean of 11.9 weeks. Stabilisation improved the function of the hand affected with paralysis and the appearance of the extensively paralysed upper limb with a flail hand. In the absence of bony abnormality fusion can be obtained with a DCP alone without the need for bone grafting.

  • Article: Cysticercosis of the flexor digitorum profundus muscle producing flexion deformity of the fingers.
    G A Anderson, S M Chandi
    [show abstract] [hide abstract]
    ABSTRACT: Selective flexion deformity of the middle and ring fingers resembling a mild type of Volkmann's contracture resulted from Cysticercus cellulosa infection within the deep flexor muscle of the forearm in a middle-aged woman. Excision of the fibrotic segment of the muscle and tenodesis of all the flexor profundus tendons restored normal range of motion to these fingers. Vascular compromise in addition to the inflammatory response to the infection were considered causes for the deformity. There is no previous report of this kind in the literature.

  • Article: Opponensplasty by extensor indicis and flexor digitorum superficialis tendon transfer.
    G A Anderson, V Lee, G D Sundararaj
    [show abstract] [hide abstract]
    ABSTRACT: From 1977 to 1988, 166 patients with median nerve paralysis of varied aetiology underwent opponensplasty. In 50 of these the extensor indicis was used, and in 116 the flexor digitorum superficialis of the ring finger. An analysis of these hands showed that the EI opponensplasty was best in supple hands and FDS opponensplasty was more suitable for less pliable hands. There were fewer complications seen after FDS opponensplasty if the detachment of the donor tendon was done through a volar oblique incision rather than the conventional lateral incision.

  • Article: Extensor indicis proprius opponensplasty.
    G A Anderson, V Lee, G D Sundararaj
    [show abstract] [hide abstract]
    ABSTRACT: An analysis of 39 patients (40 hands) who underwent an extensor indicis proprius opponensplasty was carried out. Of these, 29 hands had simultaneous adjuvant surgery to correct other deformities. The mean follow-up period was 33.8 months. Excellent or good results were seen in 87.5%, fair in 10% and poor in 2.4% hands.
