Double jersey finger: A systematic review and case series

Area of Science:

• Orthopedics
• Hand Surgery
• Traumatology

Background:

• Closed flexor tendon avulsions, commonly affecting the flexor digitorum profundus (FDP), result from finger hyperextension.
• Simultaneous avulsion of both FDP and flexor digitorum superficialis (FDS) tendons in the same finger is an uncommon injury that presents significant surgical and prognostic challenges.

Purpose of the Study:

• To detail a case of simultaneous FDP and FDS rupture.
• To emphasize accurate diagnosis and surgical management strategies.
• To conduct a systematic review of English case studies on presentation, diagnosis, treatment, and outcomes of simultaneous FDP and FDS avulsions.

Main Methods:

• A case study approach was employed for two patients with simultaneous FDP and FDS avulsions.
• A systematic review adhering to 2020 PRISMA guidelines was performed on English case studies.
• The review focused on presentation, diagnosis, treatment, and outcomes of simultaneous flexor tendon avulsions.

Main Results:

• Two cases of simultaneous FDP and FDS avulsions were successfully treated using micro-Mitek suture anchors and early active mobilization.
• The systematic review included 16 studies after screening and eligibility assessment, with 70 initial records identified.
• Micro-Mitek suture anchors demonstrated advantages in repair strength and facilitating early mobilization for better functional recovery.

Conclusions:

• Personalized surgical planning, precise timing, appropriate techniques, and comprehensive postoperative rehabilitation are crucial for managing rare and complex hand injuries like simultaneous FDP and FDS avulsions.
• The use of micro-Mitek suture anchors facilitates robust repair and early functional recovery.
• Further research is warranted to optimize management strategies for these complex injuries.
