Abstract
We investigated thumb joint stability and patient-reported and functional outcomes a minimum of 1 year after flexor digitorum superficialis opponensplasty and ligament reconstruction in 23 thumbs of 20 consecutive children with radial longitudinal deficiency. In total, 15 thumbs had preoperative multidirectional instability in the metacarpophalangeal joint. We reconstructed 22 ulnar and 16 radial collateral ligaments. At follow-up, all the metacarpophalangeal joints were stable ulnarly. Seven metacarpophalangeal joints were unstable radially despite ligament reconstruction but had no related complaints. We recommend the flexor digitorum superficialis opponensplasty as a safe and reliable procedure in hypoplastic thumbs to create stability and augment thumb strength.

Congenital hand surgeon Jan-Ragnar Haugstvedt operated on two of the cohort’s patients. We thank him for introducing the FDS4 opponensplasty in hypoplastic thumbs to our hand unit in 2009. We thank Professor Gilles Dautel, Nancy, France, for teaching us his reconstructive MCPJ technique, illustrated in his cited 2013 paper. We thank the Norwegian Professional Network for Congenital Limb Anomalies for supporting the writing of this paper with a research grant, and orthopaedic surgeon Andreas Lødrup, Oslo University Hospital, for the two illustrations.
