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

• Tendon lesion
• Lesion of the branches of the posterior antebrachial cutaneous nerve
• Incomplete removal of the synovium with risk of recurrence

Management

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

Acute Complications

• Bleeding/Hematoma
• Infection/Wound Healing Disorder

Management

• In case of relevant hematoma, operative revision
• In case of infection, immediate operative revision
• In case of wound healing disorder, operative revision depending on the severity of the findings

Late Complications

• Two-stage Tendon Rupture
• Recurrence
• Protracted Scar Pain/Neuroma Pain
• Restriction of Movement
• CRPS (Sudeck's Disease)

Management

• Tendon Reconstruction
• In case of corresponding symptomatic complaints, re-resection
• In case of scar pain/neuroma pain/neuropathic pain, watchful waiting, possibly desensitization therapy
• In case of CRPS, appropriate therapy of the disease (see specialist literature)
