Endoscopic Resection of Giant Cell Tumor of the Extensor Tendon of the Foot.

ABSTRACT: The localized form of giant cell tumor of the tendon sheath is one of the most common soft tissue tumors of the foot and ankle region. It is characteristically a benign, sharply localized peritendinous fibrous mass in the synovial or tendinous spaces. The purpose of this Technical Note is to present the technical details of endoscopic resection of giant cell tumor of the extensor tendon of the foot with preservation of the tendon. It is indicated in the localized form of giant cell tumor of the extensor tendon at the foot dorsum. It is contraindicated in cases with a diffuse giant cell tumor, a giant cell tumor of the extensor tendon at the phalangeal level, or involvement of the flexor tendon.

Project description:BACKGROUND:While some traumatic closed index extensor tendon ruptures at the musclotendinous junction have been previously reported, closed index extensor tendon pseudorupture due to intertendinous attenuation is exceedingly rare with only one case report of a gymnastics-related sports injury in the English literature. Herein, we report two non-sports injury related cases of traumatic index extensor tendon attenuation mimicking closed tendon rupture, including the pathological findings and intraoperative video of the attenuated extensor indicis proprius tendon. CASE PRESENTATION:A 28-year-old man and a 30-year-old man caught their hands in a high-speed drill and lathe, respectively, which caused a sudden forced flexion of their wrists. They could not actively extend the metacarpophalangeal joints of their index fingers. Intraoperatively, although the extensor indicis proprius and index extensor digitorum communes tendons were in continuity without ruptures, both tendons were attenuated and stretched. The attenuated index extensor tendons were reconstructed either with shortening by plication or step-cut when the tendon damage was less severe or, in severely attenuated tendons, with tendon grafting (ipsilateral palmaris longus) or tendon transfer. Six months after the operation, the active extension of the index metacarpophalangeal joints had recovered well. CONCLUSIONS:Two cases of traumatic index extensor tendon attenuation were treated successfully by shortening the attenuated tendon in combination with tendon graft or transfer. We recommend WALANT (wide-awake local anesthesia and no tourniquet) in the reconstruction surgery of index extensor tendon attenuation to determine the appropriate amount of tendon shortening or optimal tension for tendon grafting or transfer. Intraoperative voluntary finger movement is essential, as it is otherwise difficult to judge the stretch length of intratendinous elongation and extent of traumatic intramuscular damage affecting tendon excursion.
