Extensor Pollicis Longus Tendon

We present an original technique for determining the tension of the extensor pollicis longus tendon after reconstruction. We treated 20 patients using this technique for an extensor pollicis longus tendon graft or extensor indicis tendon transfer and reviewed the results. The tension of the reconstructed extensor pollicis longus was adjusted so that the centre of the distal edge of the thumbnail was elevated 2 cm above the operation table. The mean retropositional distance of the treated thumbs was 1.2 cm less than the contralateral thumbs. The mean total active motion of the thumb was 90%. This technique resulted in satisfactory thumb function. Level of evidence: IV

Dorsal Tubercle

Fourteen cadaveric wrists were dissected to investigate a modified dorsal approach that involved osteotomy of the small and dorsal tubercles without opening the third compartment. This approach could be safely made with good exposure of the dorsum of the wrist. The mean normal angle formed by the extensor pollicis longus tendon at the level of the dorsal tubercle was 144°. An approach that involves division of the third compartment may lead to effective lengthening of the extensor pollicis longus musculotendinous unit by 8 to 17 mm with corresponding decrease in the tension generated by its contraction. The modified approach permits restoration of the normal alignment of the extensor pollicis longus tendon, and may be useful for performing arthrodesis of the non-rheumatoid wrist in young manual workers.

Difficult Area

We report on the outcomes of flexor tendon repair in zone 2 subzones with early active mobilization in 102 fingers in 88 consecutive patients. There were 28, 53, 15, and six fingers with repairs in zones 2A to 2D, respectively. Rupture of the repair occurred in four fingers, all in zone 2B. Excluding those with repair ruptures, the mean total active motion was 230° (range 143°–286°). Evaluated with Tang’s criteria, the outcomes were ranked excellent in 39 fingers, good in 46, fair in ten, poor in three, and failure in four. The outcomes in zone 2C were significantly inferior to those in zones 2B and 2D ( p = 0.02). Our results suggest that the tendon laceration in the area covered by the A2 pulley (zone 2C) is the most difficult area to obtain satisfactory active digital motion and tendon repair in zone 2B is the area where the risk of rupture is highest.

The Mean

The aim of this study was to compare two joint sparing Kirschner-wire fixation techniques for displaced proximal phalangeal neck fractures. Forty-six patients with proximal phalangeal neck fractures managed by either percutaneous antegrade flexible intramedullary nailing (Group I) or crossed Kirschner-wires (Group II) were recruited for a randomized prospective comparative study. Clinical and radiological assessment of all patients was done in addition to the Kang scoring system, Disability of Arm, Shoulder and Hand score and total active motion. The mean time for radiological union for both groups was 5.8 weeks. The mean postoperative total active motion, Kang and the Disability of Arm, Shoulder and Hand scores were better in Group I patients, but without any statistically significant differences. Closed reduction and percutaneous Kirschner-wire fixation by a joint sparing approach will yield good functional results with no or minimal complications in proximal phalangeal neck fractures.

High Level

This study evaluated recovery of sport performance and correction of bowstringing after surgical reconstruction of closed finger pulley rupture in high-level rock climbers. A total of 38 patients treated with an extensor retinaculum graft were assessed. The mean follow-up time was 85 months, and 30 patients returned to their previous climbing level. The mean total active motion score was 96% of the opposite side. All patients had an excellent Buck-Gramcko score. There was no significant difference in grip strength and tip pinch strength in the crimp position between the injured side and the opposite side. A total of 31 patients were examined with ultrasonography. In 18, flexor bowstringing effects had returned to near-normal values. There was an association between rock climbing level recovery and the flexor bowstringing correction (odds ratio, 6.9; 95% confidence interval, 1.1–42.8). If flexor bowstringing was corrected, patients were more likely to regain their preinjury sport performance. The ultrasonography measurement was a useful tool for predicting functional recovery.

Flexor Digitorum Profundus Tendon

We report the outcomes of repair of the flexor digitorum profundus tendon in zone 2a in 22 fingers. The tendon was repaired with a six-strand repair method and the A4 pulley was completely released. Release of the C2 pulley combined with the A4 pulley was necessary in 12 fingers, nine fingers underwent a complete release of the A3, C2, and A4 pulleys, and one finger underwent a release of the C1, A3, C2, and A4 pulleys. The mean total active motion of the three finger joints was 234° at 5 to 12 months of follow-up. No bowstringing was noted in these fingers. The good and excellent recovery of active digital motion was in 20 (91%) out of 22 fingers according to Strickland’s criteria or Tang’s criteria. Our results suggest that release of the A3, C2, and A4 pulleys makes the repair surgery easier and does not cause tendon bowstringing. Level of Evidence: IV
