We present the results of 26 patients with 31 consecutive displaced or unstable extra-articular fractures of the base and shaft of the proximal and middle phalanges of the digits of the hand, treated over a period of 12 months with an intramedullary headless compression screw and early mobilization with no splinting. All fractures healed with no major complications. Only one patient, who had a pathological fracture through an enchondroma, required a tenolysis to improve the mobility of the finger. This technique seems to be technically simple, effective and with few drawbacks. Level of evidence: IV

We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M-Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of the repaired tendons, including complete division of the A4 or A2 pulleys when necessary. In nine fingers, we repaired one slip of the flexor digitorum superficialis tendon and resected the other half. When the flexor digitorum profundus tendon would not glide under the A2 pulley, we excised the remaining slip of the flexor digitorum superficialis tendon. The wrist was splinted in mild extension post-surgery with early commencement of tenodesis exercises. No tendon repair ruptured. By the Strickland criteria, out of 27 fingers, 18 had excellent, six had good, two had fair, and one had poor results. We conclude that a strong core suture (such as the M-Tang repair) without peripheral sutures, and with division of pulleys as necessary is safe for early active motion and yields good outcomes. Level of evidence: IV

The aim of this study was to quantify the articular cartilage defect created with two different antegrade techniques of intramedullary osteosynthesis with a headless compression screw inserted through the metacarpophalangeal joint. In 12 out of 24 fingers from six cadaveric hands, a trans-articular technique with cannulated headless compression screws (2.2 and 3.0 mm diameter) was used; whereas in the other 12 fingers, an intra-articular fixation technique was used. The areas of the articular surface and the defects created were measured with a digital image software program. All measurements were made twice by two observers. In the intra-articular technique, the average defect in the base of the articular surface of the proximal phalanx was 4.6% with the 2.2 mm headless compression screw and 8.5% with the 3.0 mm screw. In the trans-articular technique, the defect size was slightly smaller; 4.2% with the 2.2 mm screw and 8% with the 3.0 mm screw, but the differences were not statistically significant. The main advantage of the intra-articular technique was that it avoided damage to the articular surface of the metacarpal head.

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.
