INTRODUCTION: Zone 3 mid-substance flexor tendon ruptures not only are exceptionally rare but also can clinically masquerade as zone 1 "Jersey finger" during forceful distal interphalangeal joint extension trauma, which can lead to challenges in both conducting diagnosis and surgical intervention planning.
CASE REPORT: A 58-year-old Caucasian gentleman presented with right little finger pain and deformity. He was referred to the orthopedic department as a "Jersey finger.. The mechanism was innocuous and incongruent with the pathology. It involved pulling and pushing a standard household doorknob. He described a "snap and pop" sensation and pain over his mid-palm A1 pulley level. Clinically, his finger demonstrated flexor digitorum profundus (FDP) function loss and flexor lag deformity. He was also found to have an unusual presentation of diffuse tenderness along the A1 pulley toward zone 3 metacarpal levels. Magnetic resonance imaging (MRI) was performed to fully elucidate the pathology. A complete mid-substance full-thickness tendon rupture was identified in zone 3. It was at the level of the metacarpal base. Primary tendon repair was performed with two minimally invasive surgical incisions (fifth metacarpal Brunner incision and carpal tunnel approach) while using a Lim-Tsai six-strand cruciate core tendon repair technique with circumferential 5' proline reinforcement. After his early active range of motion (ROM) flexor protocol hand therapy, the patient fully regained active ROM and strong grip functional recovery during his 6th-week post-operative review.
CONCLUSION: In this case report, we demonstrated that zone 3 mid-substance full-thickness FDP tendon ruptures can mimic Jersey finger injury as an unusual clinical presentation. Therefore, thorough clinical assessment and radiographic investigations (ultrasound or MRI) are crucial to identify precise ruptured tendon stump locations and guide primary tendon repair with minimal invasive surgical approach. As a result, patients can benefit from having minimal surgical scar tissue while reducing the risk of infection and regaining early functional recovery.
