Bilateral Achilles Tendon Rupture Simulating Peripheral Neuropathy: Unusual Complication of Steroid Therapy

Tendon injury and repair mechanics

“…Both drugs cause dysplasia of collagen fibrils, which decreases tendon tensile strength. Systemic and local corticosteroids have been widely implicated in tendon rupture (Dickey and Patterson, 1987;Newnham et al, 1991). However, studies on the patella tendon show that normal tendon is not damaged by intratendinous injection of steroids (Matthews et al, 1974).…”

Mini-Open Tenorrhaphy of Acute Achilles Tendon Ruptures

“…18,28,35,37 Commonly, Achilles tendon ruptures affect men between 30 and 50 years of age, 7,31 with a male-tofemale ratio of 1.7:1 to 12:1. 5,43,53 The injury's origin is not fully understood yet, 5,15,22,34 but a rupture generally occurs through a previously degenerated tendon 15,21,55,56 or is associated with the use of medications such as steroids 11,38 and quinolones 44,46 or with some other conditions such as mechanical abnormalities of the foot 9 and exercise-induced hyperthermia. 56 The purpose of treatment is to recover a normally functioning gastrocsoleus complex, and the best option to achieve this is still controversial.…”

Augmented Repair of Acute Achilles Tendon Rupture Using an Allograft Tendon Weaving Technique

“…A comparative cohort study by Tallon et al (21) showed that the degree of degeneration in the ruptured tendon is greater than that in tendinopathy. Some drugs, such as corticosteroids (22) and fluoroquinolone antibiotics (23), are also known to predispose the tendon to rupture. However, the mechanism of acute tendon rupture is still not well known.…”
