A pathological investigation was carried out on tenosynovitis with rupture of the gastrocnemius tendon occurring in young and adult broiler chickens. Tenosynovitis has been seen mainly in the gastrocnemius tendon sheath and tended to be chronic in character, showing a proliferation of juvenile fibrous tissue in the subsynovial layer. Complete rupture of the gastrocnemius tendon occurred in eight of 12 young chickens (50-71 days of age). Nodular fibrous thickening in the tendon-muscle junction was observed in fourteen of 16 adult chickens (181 or 235 days of age) and one young chicken. It was associated with partial rupture of the tendon in four of these chickens. The thickening was regarded as a healing process of the partial rupture. Tenosynovitis was regarded as a precursor of rupture of the tendon. Accordingly, tenosynovitis and rupture of the gastrocnemius tendon may be in the same entity of disease. Secondary lesions were observed in the muscle and nerve fibers in the leg.
