Wound Dehiscence Following Cubital Tunnel Surgery

Area of Science:

• Orthopedic Surgery
• Neurology
• Wound Healing

Background:

• Cubital tunnel syndrome is a common compressive neuropathy requiring surgical intervention.
• Surgical options include simple decompression and ulnar nerve transposition.
• Wound dehiscence is a potential complication, but its causes and risk factors are not well understood.

Purpose of the Study:

• To investigate the incidence and risk factors of wound dehiscence after cubital tunnel surgery.
• To compare wound dehiscence rates between simple decompression and ulnar nerve transposition.

Main Methods:

• Retrospective evaluation of 1,401 patients undergoing ulnar nerve surgery (2016-2019).
• Data collected included patient demographics and medical history to identify risk factors for wound dehiscence.
• Patients were assessed for wound dehiscence within 3 months post-surgery.

Main Results:

• The overall wound dehiscence rate was 2.5% (35/1,401).
• Rates were similar between simple decompression (2.7%) and transposition (1.7%), with no statistically significant difference.
• No significant association was found between wound dehiscence and age, BMI, smoking, or comorbidities.

Conclusions:

• Wound dehiscence can occur after both cubital tunnel decompression and transposition.
• Surgeons should advise patients to protect surgical wounds for several weeks post-operation.
• Suboptimal vascularity in the elbow's soft tissue may contribute to dehiscence, often treatable by secondary intention healing.
