The first annular (A1) pulley is an important structure of the hand, providing a biomechanical support to the metacarpophalangeal joint and maintaining joint stability and flexor tendon alignment. Albeit uncommon, disruption of this pulley can result in dislocation or ulnar drift of the digit, particularly pronounced in patients with rheumatoid arthritis. Despite this, the A1 pulley is commonly divided without reconstruction in trigger finger. Several annular pulley reconstructive techniques have been developed to preserve its function. However, development of recurrent triggering has been observed due to fibrosis, largely due to inadequate release of the pulley. We have developed a technique to increase the volume within the flexor sheath while preserving the A1 pulley by way of stepwise lengthening. This has enabled an increase in the diameter of the pulley to 4 times its original size. A prospective study was performed comprising 10 trigger finger releases with stepwise lengthening of the A1 pulley. In all patients, there were no complications, and good hand function was achieved with no recurrence of triggering at 6 weeks of follow-up. This technique can thus safely achieve trigger release without sacrifice of the function of the A1 pulley.
Meniscal radial root tears can disrupt the load-bearing function of the meniscus and worsen instability in anterior cruciate ligament–deficient knees. Paracentral radial tears adjacent to the root (types 1, 2, and 4) repaired with a transtibial pullout suture technique can lead to over-medialization of the meniscal root and a high-tension nonanatomic repair. We propose 2 all-inside techniques for anatomic repair of medial and lateral meniscal radial root tears with (1) an all-inside meniscal repair device and (2) an antegrade suture passer. We present the technical requirements and tips for these techniques. For lateral meniscal radial root repair with an all-inside meniscal repair device, ideal viewing is from an anterolateral portal with device entry from an anteromedial portal to reduce the risk of vascular injury. We recommend at least 2 stitches across the tear, with the depth setting limited to 18 to 20 mm for a central stitch and 16 mm or less for a peripherally placed stitch. For root repair with an antegrade suture passer, viewing should be from an anteromedial portal with the passer entering from an anterolateral portal. At least 2 stitches should be placed across the tear, with 1 central and 1 peripheral or 1 superior and 1 inferior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
