Complications of flexor tendon repair in the hand: MR imaging assessment.

Abstract

MR imaging may enable distinction among several complications that occur after repair of an injured digital flexor tendon.

Sonographic Differentiation of Digital Tendon Rupture From Adhesive Scarring After Primary Surgical Repair

“…Because of equivocal clinical findings, differentiating adhesive scarring from complete or partial tendon rupture may be difficult. 8,9 Adhesive scarring between tendon, synovial sheath, and adjacent ligaments after primary flexor and extensor tendon repair is reported to occur in 20% and 17% of patients, respectively. [1][2][3][4] The sonographic appearance of a normal tendon shows a fibrillar pattern of parallel hyperechoic lines when viewed in the longitudinal plane (Fig.…”

“…Several imaging modalities have been used to assess and characterize primary and secondary tendon injuries including magnetic resonance imaging (MRI), [7][8][9] computed tomography, 10 and sonography. [11][12][13][14] Currently, MRI [7][8][9] and sonography [11][12][13][14] are the primary imaging modalities for evaluating tendon and ligamentous injuries of the hand.…”

“…[11][12][13][14] Currently, MRI [7][8][9] and sonography [11][12][13][14] are the primary imaging modalities for evaluating tendon and ligamentous injuries of the hand. In 2 studies MRI was found to have both high sensitivity and specificity in detecting digit tendon rupture after primary tendon repair.…”

“…In 2 studies MRI was found to have both high sensitivity and specificity in detecting digit tendon rupture after primary tendon repair. 8,9 Magnetic resonance imaging provides excellent softtissue resolution but has marked limitations including expense, accessibility, required use of specialized surface coils, claustrophobia, and movement-related artifacts, and it is contraindicated in patients with cardiac pacemakers, defibrillators, or prior cerebral aneurysm surgery. Most importantly MRI does not permit dynamic evaluation of the tendons.…”

“…Αυτό απαιτεί επαναληπτική αρθροσκόπηση για την αφαίρεση των συμφύσεων και την ανακούφιση των ασθενών [135] . Η ανάπτυξη συμφύσεων στο δακτυλικό τενόντιο έλυτρο μετά από αποκατάσταση τραυματισμένου τένοντα δακτυλικού καμπτήρα, αποτελεί συχνή επιπλοκή [136] .…”
