Acute and late radial collateral ligament injuries of the thumb metacarpophalangeal joint

Results of Surgical Treatment of Acute and Chronic Grade II Tears of the Radial Collateral Ligament of the Thumb Metacarpophalangeal Joint

“…5 Therefore the Stener lesion 11 rarely 4 occurs on the radial side because both ends of the ligament remain deep to the aponeurosis. 2,5 Many researchers have advocated a more conservative approach for acute injuries to the RCL than for those to the UCL because there is no interposing aponeurosis to prevent primary healing. 6,7 The ulnar pull of the extensor pollicis longus tendon, however, tends to maintain the ulnar deviation after RCL tears and allows healing with the ligament elongated.…”

Radial Collateral Ligament Injuries of the Thumb

“…When the UCL ruptures, it can be displaced proximally and dorsally to the adductor, leading to the formation of the Stener lesion. 7,10,11 This is contrasted with the radial side of the joint where the APB is located dorsal to the MCP joint axis and completely overlies the RCL, thus precluding the formation of a Stener lesion (Fig. 1).…”

Thumb collateral ligament injuries in the athlete

“…There was a slight loss of motion at the MCPJ in both groups, which was significant only in the late repair group. The acute repair group had an 11% decrease in motion at the MCPJ, while the late repair group had a 23% decrease in motion at the MCPJ [63].…”

“…Durham et al [63] investigated a group of 18 patients with RCL injuries, six of whom underwent acute repairs (within 2 months), and 12 of whom underwent late repairs (after 2 months). The early repairs included midsubstance suture repairs, reattachment to the bony metacarpal origin, and pinning of distal avulsions.…”
