Complications - Removal of a tendon sheath hygroma/extensor tendon synovectomy with retinaculum plasty

• Tendon lesion
• Lesion of the branches of the N. cutaneus antebrachii posterior
• Incomplete removal of the synovia with risk of recurrence

Management

• Primary tendon suture or tendon plasty
• Careful and as complete as possible removal of the altered synovial tissue

Acute Complications

• Bleeding/Hematoma
• Infection/Wound healing disorder

Management

• In case of significant hematoma, surgical revision
• In case of infection, immediate surgical revision
• In case of wound healing disorder, surgical revision depending on the severity of the condition

Late Complications

• Delayed tendon rupture
• Recurrence
• Prolonged scar pain/neuroma pain
• Restriction of movement
• CRPS (Sudeck's disease)

Management

• Tendon reconstruction
• Re-resection in case of corresponding symptomatology
• In case of scar pain/neuroma pain/neuropathic pain, wait-and-see approach, if necessary, desensitization therapy
• In case of CRPS, appropriate treatment of the disease (see specialist literature)
