RESUMO
A century ago the remains of a dog skeleton were found in an archaeological double human burial, near Bonn-Oberkassel (Germany). Recent re-examination of the dog remains revealed that they were about 14,500 years old. Based on the growth plates, the animal was considered to be approximately 7·5 months old at the time of death. Based on the minimal humeral diameter, it was calculated that it was approximately 0·47 m tall at the shoulder and weighed approximately 15·7 kg. The right proximal ulna of this skeleton showed osteoarthritis, manifested by an osteophyte of 5×3×1·5 mm3 at its cranial edge, with no identified primary developmental causes for osteoarthritis. Osteochondritis dissecans, joint incongruity and trauma are possible aetiologies. The left ulna did not reveal any abnormalities.

Triple pelvic osteotomy (TPO) was used to treat a selected group of young dogs with clinical and radiographic signs of hip dysplasia. Good clinical outcomes have been reported in dogs between 17-85 kg body weight. Hip dysplasia however is also encountered in smaller dogs. If surgery is performed in smaller dogs, femoral head and neck ostectomy is the main treatment method used. We wanted to determine if TPO could also be used in dogs under 12 kg bodyweight. Our study showed that it is technically possible to perform TPO surgery in dogs less than 12 kg of weight (down to 4.6 kg) with a good clinical outcome even in hips with high angles of reduction and subluxation.

A retrospective study of 62 dogs that underwent unilateral triple pelvic osteotomy with a Slocum triple pelvic osteotomy plate and Synthes 3.5 mm cortical screws. We compared the probability of screw loosening after six weeks in dogs in which pre-tapped screws were used (30 dogs), with dogs in which self-tapping screws were used (32 dogs). Screw loosening was significantly less prevalent with self-tapping screws than pre-tapped screws.
