A 15-year-old Cocker Spaniel was referred to for the evaluation of left forelimb lameness. Radiographic and computed tomography examinations revealed osteolysis of the proximal left third, fourth and fifth metacarpal bones and pathological fractures of the proximal left fourth metacarpal bone. Histopathological examination via bone biopsy did not provide a definitive diagnosis, and the owner elected limb-sparing surgery. The fourth metacarpal bone and digits were amputated. Subsequently, autologous bone grafts were performed on the lytic area of the third and fifth metacarpal bones. The dog showed improvement in gait 7 weeks after reconstructive surgery. Chronic non-bacterial osteomyelitis (CNO) was diagnosed by exclusion. To the best of our knowledge, CNO has not been previously reported in dogs.

From the Division of Plastic and Reconstructive Surgery, Children's National Hospital, Washington, DC.
Article Synopsis
- Calcifying aponeurotic fibroma is a rare tumor affecting the upper extremities, particularly challenging when it involves deep spaces of the hand.
- A case study discusses a 9-year-old girl with a growing mass on her palm, diagnosed later due to its deep location and lack of symptoms, which led to a larger than normal size.
- The girl underwent a careful surgical procedure to remove the tumor while preserving surrounding structures, and at her 1-year follow-up, there were no signs of recurrence.

Objectives: To enhance our understanding of the evolutionary dynamics of the modern human hand by analyzing the degree of integration and ability to respond to selection pressures of each phalanx and metacarpal bone.
Materials And Methods: The sample comprised 96 adult individuals, both female and male, from Euro-American, Afro-American, and European populations. We collected 10 linear measurements from the 19 metacarpals and proximal, middle, and distal phalanges that constitute the five digits of the hand.
