Camptodactyly Treatment Options: A Comprehensive Guide

Camptodactyly is a fixed flexion deformity of the proximal interphalangeal (PIP) joint (usually little finger), often congenital or adolescent-onset.

Conservative Treatment (First-Line, Especially <45°)

• Dynamic Splinting: Custom thermoplastic or prefabricated (e.g., Oval-8, Silver Ring) worn 12–20 hrs/day. Applies low-load prolonged stretch.
• Serial Casting: Weekly cast changes with progressive extension (for >45° or rigid).
• Occupational/Physical Therapy: Passive stretching, active extension exercises, tendon-gliding, modalities (ultrasound, heat).
• Nighttime Static Splinting: Maintains gains.

Surgical Indications

• Fixed contracture >45–60° failing 6+ months conservative therapy.
• Functional impairment (grip, pinch, ADLs).
• Progressive worsening in adolescence.

Surgical Options

• Soft Tissue Release: Fasciotomy, tenolysis (A1/A2 pulley), volar plate/ collateral ligament release, FDS lengthening/transfer.
• PIP Joint Arthrodesis (Fusion): Salvage for severe arthritis/joint destruction; functional position (20–30° flexion).
• Tendon Transfers: FDS → extensor mechanism (rare).

Post-Operative Protocol

• Immobilization (1–2 weeks) → dynamic splinting + therapy (6–12 weeks).
• Night splinting 6–12 months to prevent recurrence.

Outcomes

Conservative: 60–80% improvement if early/compliant. Surgical: 30–50° correction typical; residual stiffness common. Recurrence risk ~20%.

Early referral to hand surgeon/therapist optimizes outcomes.
