Trigger Thumb in Infants

Pediatric Trigger Thumb in Identical Twins: Congenital or Acquired?

“…The tendon sheath (A1 pulley) can be thickened as well, 21 as shown on ultrasound in both of our cases (Figure 2). Microscopically, the specimens from the A1 pulley (Figure 3B) were unremarkable in both of our cases.…”

“…Bilateral pediatric trigger thumb was reported in a girl and her mother by Vyas and Sarwahi18 and a sister and her brother by McCarroll 6. A positive family history was found in 6 cases by Van Genechten,19 6 cases by De Smet et al,20 6 cases by Steenwreckx et al,3 2 cases by White and Jensen,21 2 cases by Ger et al,4 and in 19% by Hudson et al1…”

Pediatric Trigger Thumb with Metacarpophalangeal Joint Hyperextension or Instability

“…Pediatric trigger thumb with concomitant MCPH and MCPI occurs frequently, but there are only sporadic reports focused on the occurrence of individual secondary MCPH after non-surgical manipulation and extension splint fixation [ 8 , 24 , 25 ]. Lee warned against prolonged passive stretching because the possibility of producing hyperextension of the MCP joint; iatrogenic hyperextension at the MCP joint following splinting was noted and should be avoided [ 26 ]; but for the treatment of MCPH, only one related article reported 7 cases of volar plate advancement [ 9 ].…”

Surgical Release of the Pediatric Trigger Thumb

“…7, 19 Slakey and Hennrikus 21 found a flexion contracture of the IP joint averaging 35°(range, 20°to 50°) in 15 children. The IP joint is most frequently locked at about 30°of flexion, 18 and the mean flexion deformity is about 27°. 8 Other authors did not report the degree of flexion contracture.…”

“…[3][4][5][6][7] One of the main concerns with conservative management is whether the child should be splinted during the observation period. Although White and Jensen 18 found it difficult to employ splinting in young children, other authors found splint, therapy, or both to be effective. [3][4][5][6][7] In these series, the overall success rate was 78% for a mean period of treatment of 15 months.…”
