Patient Characteristics in Ulnar Nerve Compression at the Elbow at a Tertiary Referral Hospital and Predictive Factors for Outcomes of Simple Decompression versus Subcutaneous Transposition of the Ulnar Nerve

الملخص EN

Patient characteristics and predictive factors for outcomes were analysed in 202 cases undergoing simple decompression, primary subcutaneous transposition, or secondary subcutaneous transposition for ulnar nerve compression at the elbow at a tertiary referral hospital.

Data from medical charts and a survey were evaluated.

The mean patient age was 49 years with revision surgery cases being significantly younger.

Sixty-one percent of cases were female, and 31% were smokers.

The comorbidity was extensive, including other nerve compression lesions as well as neck and shoulder problems.

Overall, 53% reported being pleased with the result of surgery and 57% of the cases rated function as better or completely recovered after surgery.

The median postoperative DASH (Disabilities of the Arm, Shoulder and Hand) score was 26 (IQR 11–49), which is in accordance with unpublished national data.

No significant differences in DASH scores were found between surgical groups, but a higher preoperative McGowan grade was significantly associated with a poorer postoperative DASH score.

Women scored greater disability postoperatively than men.

There was a significantly increased risk of complications, which was doubled for smokers, following primary and secondary transposition compared to simple decompression.

Surgical cases with ulnar nerve compression treated at a tertiary referral hospital constitute a heterogeneous group with great comorbidity and frequent concomitant nerve compression lesions.

We suggest simple decompression as the procedure of first choice.

Transposition can be used in selected cases or when simple decompression fails.

All patients should be strongly recommended to stop smoking considering the remarkably increased risk for complications among smokers.
