Sixty one samples of the distal parts of limbs were obtained from different ages of buffalo and camels of both sex to study the synovial structures to determine the suitable sites for injection of surgical interference. The result showed that extensor digit synovial sheath was extend between middle or distal part of metacarpal (metatarsal) to the extensor processes and this formed with synovial capsule dorsal pouches which serve in surgical interference. The flexor digit synovial sheath extended to palmar (planter) between distal extremity of metacarpal (metatarsal) to the middle of second phalanx in buffalo while in camel it extended to the proximal extremity of second phalanx, that sheath was formed with suspensory ligament and sessamoid bone palmar or planter pouches which were serve the surgical interference. Fourth synovial bursa observed situated dorsally between the extensor digit laterals tendon and capsule of fetlock joint, forms site of injection during surgical interference, while the other two synovial bursa were located to palmer (planter) between deep flexor tendon and distal sessamoid bone in buffalo while in camel these bursa were located between deep flexor tendon and cartilage of the second phalanx, these bursa were served for surgical interference. The synovial capsule which serve the surgical interference through digit cushion these were shown extended from the claw capsule. The result show that surgical interference was form six pouches in buffalo and eight pouches in camel, which formed by synovial structures and the tissue associated with them.
