Combined arthroscopic and open operative management of an intramuscular supraspinatus lipoma in the treatment of subacromial impingement syndrome: A case report

Endoscopically Assisted Myectomy for Intramuscular Lipoma of Pronator Quadratus

Intramuscular lipoma is usually growing infiltratively and can affect any muscle, although the proximal muscles of the extremities are mostly commonly involved. This lesion can occur in the pronator quadratus. Because of muscle is small and deep seated, the intramuscular lipoma usually involves the whole muscle and even has an extramuscular component before it presents clinically. In this Technical Note, we report the technique of endoscopically assisted myectomy of the pronator quadratus for infiltrating intramuscular lipoma of the muscle. This has the advantage of minimally invasive surgery of minimal soft tissue dissection and fewer soft tissue complications.
