Compressive Femoral Neuropathy Associated with Iliopsoas Hematoma Complicating Hip Hemiarthroplasty: A Case Report.

INTRODUCTION

Femoral nerve compression caused by iliopsoas hematoma is a rare complication after hip surgery. To the best of our knowledge, this is the first case after hemiarthroplasty. In this case, iliacus hematoma resulted from spontaneous bleeding favored by anticoagulant therapy.

CASE REPORT

A 78-year-old female developed left groin pain associated with typical symptoms of femoral nerve palsy about 2weeks after left hip hemiarthroplasty[1, 2, 3]. Computed tomography revealed the presence of a left iliopsoas hematoma that was surgically drained. Inguinal pain was immediately relieved, while nerve palsy recovered only partially, but the quality of life drastically improved and she was able to walk using a walker without pain.

CONCLUSION

Even if it is a rare condition, the formation of a hematoma of iliopsoas muscle should be considered in patients that present symptoms of femoral nerve palsy, especially if treated with heparin or other anticoagulant drugs. Surgical drainage of the hematoma is indicated when symptoms are severe and disabling, and in this way, surgery could improve quality of life.
