This study reports our treatment of divided flexor pollicis longus (FPL) tendons by primary repair from 1999 to 2002. Forty-eight FPL repairs were performed using two Kessler two-strand repairs with a cross-linked Silfverskiold circumferential suture. All were rehabilitated by early active mobilization. Excellent or good results were observed in 73/77% of cases (White/Buck-Gramcko assessments, respectively). No patients (0%) ruptured their repair as a result of early active mobilization. Two patients (4%) developed post-operative infections with wound and tendon dehiscence. This combination of repairs addresses the problem of rupture of FPL during early mobilization which we experienced in previous studies. Its problems and alternatives are discussed.

This study reports our treatment of divided flexor pollicis longus tendons by primary repair from January 2004 to September 2007. Fifty flexor pollicis longus repairs carried out using the Tang technique of three Tsuge sutures are reported in this study. A circumferential suture was not used routinely. Excellent or good results were observed in 78/82% of cases (White/Buck-Gramcko assessments, respectively). No patients ruptured repairs as a result of early active mobilization. No patients developed postoperative infections with wound and tendon dehiscence. One patient developed Chronic Regional Pain Syndrome Type 1. We have found this repair of the flexor pollicis longus tendon to be safe for early active mobilization and it is easier to perform than primary repair of this tendon using four strand Kessler-type core sutures and elaborate circumferential sutures, as reported previously.

This study reports the treatment of divided flexor pollicis longus (FPL) tendons from 1989 to 1998. The first 30 patients, in whom the tendon was repaired with a Kessler suture and simple epitendinous suture and mobilized using early active motion with only the thumb splinted, achieved 70/73% (White/Buck-Gramcko assessments respectively), excellent or good results and a rupture rate of 17%. The next 39 patients underwent the same treatment but in a splint with the thumb position altered and the fingers also splinted, with 67/72% excellent or good results and a rupture rate of 15%. The next 49 patients underwent repair with a Kessler suture and a reinforced epitendinous suture and the same mobilization as group 2, with 76/80% excellent or good results and a rupture rate of 8%. The final combination of repair and early active mobilization for primary repair of FPL tendons compares favourably with previous methods of treatment.

Swan neck deformity is a progressive and disabling condition that commonly affects rheumatoid arthritic hands. During a 4-year period, 101 fingers in 43 patients had this deformity corrected using a new procedure combining the distally based extensor lateral band technique described by Littler and the flexor digitorum superficialis (FDS)-palmar plate pulley introduced by Zancolli. The ranges of motion of the metacarpophalangeal, proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints were assessed pre-operatively and 12 months after surgery. An average PIP joint hyperextension of -13.3 degrees was converted to +13.4 degrees . The ranges of motion of the proximal and DIP joints were significantly different (Student's t-test). No patient suffered recurrence of the deformity during an average follow-up of 20 months. This new technique improves some unappealing aspects of previous techniques and provides a stable and reliable correction of swan neck deformity.
