Intratendinous Ganglion in the Extensor Digitorum Communis of the Hand: A Case Report

Ganglions are most common benign lesion of the hand and wrist. Although they usually arise from tendon sheaths, those originating within a tendon substance itself are rare. The etiology, pathogenesis and treatment of the intratendonous ganglion are not completely understood. We report a case of an intratendinous ganglion that developed in the extensor digitorum communis tendon of the hand and caused the extension limitation of the wrist. Treatments consisted of the intratendinous ganglion excision and meticulous tendon repair followed by tenosynovectomy.

Intratendinous Ganglion in the Extensor Tendon of the Great Toe: A Case Report / 대한정형외과학회잡지

A ganglion is the most common soft tissue tumor. But an intratendinous ganglion is a rare lesion of unknown etiology but with a natural history that originates within the tendon. A 52 year-old man complained of a palpable, non-tender mass in the dorsum of the right foot. We present a case of an intratendinous ganglion that developed in the extensor hallucis brevis tendon and which was treated successfully by excision.

Clinical Experience of Intratendinous Ganglion in the Extensor Tendon of Hand

Ganglion is the most common soft tissue tumor of the hand, and most of them usually arise from the scapholunate ligament, scarphotrapezial ligament, radiocarpal joint or flexor tendon sheath. However, intratendinous ganglion is very rare with unknown etiology and pathogenesis that originates within tendon. We have experienced three clinical cases of intratendinous ganglion in extensor tendons of hand. The average of patients at operation was 36 years. All patients were treated by excision of the ganglion in conjunction with tenosynovectomy followed by repair of the tendon. The length of mean follow up time was 6.7 months and all of them showed no evidence of recurrence.

In Vivo Effect of Intra-Tendinous Thermal Shrinkage on the Rabbit Patellar Tendon / 대한정형외과학회잡지

PURPOSE: In this vivo animal study, the authors evaluated the effect of thermal shrinkage on the rabbit patellar tendon using modified approaches involving intra-tendinous thermal treatment and protective immobilization. METHODS AND MEASURES: Of 30 New Zealand white rabbit patellar tendons, Twenty-five rabbits underwent tendon immobilization by fixation of the patella to the femur after thermal shrinkage of the right-side patellar tendon. Ten rabbits of those were sacrificed at 4 weeks and the other fifteen rabbits at 8 weeks. The left-side patellar tendon of twenty-five rabbits were underwent sham-control except thermal treatment. The rate of shrinkage and maximal peak stress and linear stiffness by unit area were assessed in these twenty-five rabbits. Differences between groups were statistically analyzed. Light and transmission electron microscopy examination were evaluated in all of thirty rabbits. RESULTS: The shrinkage rate immediately after thermal treatment did not change significantly at 4 and 8 weeks. The mean maximal tensile stress and linear stiffness at 8 weeks (372.30+/-164.37 N/m2 and 214.60+/-142.52 N/mm) were significantly higher than those measured at 4 weeks (233.84+/-91.12 N/m2 and 196.70+/-72.10 N/mm, respectively) allthough those were diminished when it compared with those of sham control group. Numerous collagen fibers with medium diameters and myofibroblasts indicative of a healing process were observed on histologic examination at 8 weeks. CONCLUSION: Intra-tendinous thermal shrinkage combined with a period of protective immobilization may be one of positive concern for prevention of re-stretching phenomenon as time goes by.

Ganglion in extensor tendon of the hand: case report / 대한정형외과학회잡지

Ganglion is a common clinical entity, usually superficial in location, therefore easily diagnosed and most common tumors of the hand which represent 50 to 70% of all soft tissue tumors of the hand. The soft mucin filled cyst is attached to the adjacent underlying joint capsule, tendon, or tendon sheath. The most common ganglion is the ganglion on the dorsal side of wrist, with its origin at the scapulolunate ligament and is usually located between the extensor digitorum communis of the index finger and the extensor pollicis longus tendons. Intratendinous ganglion is very rare lesion that originates within the tendon, which has been reported 10 cases in earliest articles and 1 case in Korean article. We report one case of ganglion that arose within the extensor digitorum communis of the middle finger.

Intratendinous Ganglion: A Case Report / 대한정형외과학회잡지

Ganglia are the most common soft tissue tumors of the hand. Ganglia found on the dorsum of the wrist usually arise from the scapholunate ligament and are usually located between the extensor digitorum communis tendon of the index finger and extensor pollicis longus tendon. Intratendinous ganglion is a very rare lesion of unknown etiology and natural history that originates within the tendon. A patient is described who presented with a painful mass on the dorsolateral aspect of the wrist due to an intratendinous ganglion of the extensor pollicis longus tendon. Treatment consisted of excision of the extensor pollicis longus tendon with ganglion followed by mini free tendon graft using palmaris longus tendon.
