Camptomelia in a rhesus macaque (Macaca mulatta).
(12/19)
An 8.5-mo-old female rhesus macaque was examined for an apparent lump on the right arm, below the elbow. The macaque showed no signs of pain or discomfort. Examination revealed that the lump was actually a bend in the forearm. Radiography demonstrated that some of the long bones of the animal were bowed. Differential diagnoses included rickets, hyperparathyroidism, pseudohyperparathyroidism, and a growth dysplasia. No other similar abnormalities in animals from that cage or any other enclosure in our large colony were observed. Blood chemistries and a complete hemogram were within normal limits for a macaque of this age. Serum was submitted for a vitamin D profile that included assays for parathyroid hormone, 25-hydroxyvitamin D, and ionized calcium. Serum samples from sex- and age-matched normal controls were sent for comparison and to establish a baseline profile. The affected animal had vitamin D levels comparable to unaffected controls. Bone biopsies appeared normal for a macaque of this age. Fluorine levels in the drinking water supply were within acceptable limits. Consistent with the information available, a diagnosis of idiopathic camptomelia, or bowing of the long bones, was made. In humans, developmental camptomelia is associated with several bone dysplasias in infants and children. These conditions are thought to be caused by genetic mutations in enzymes or transcription factors that control development of the epiphyses and are almost always associated with other lethal and nonlethal developmental abnormalities.

Osseous union in cases of non-union in long bones treated by osteosynthesis.
(13/19)
OBJECTIVE: To determine the incidence of osseous union in cases of nonunion of long bones managed by open reduction and compression plating. PATIENTS AND METHODS: Between November, 2003 and June, 2005, 53 patients with nonunion of long bones were treated by open reduction and internal fixation and followed up. The follow up period for each case was 6 months. Immediate post- operative x-ray was done in each case. Patients were seen in the post- operative period at 4 weeks, 6 weeks, 12 weeks, and 6 months. At each visit, clinical and radiological assessments were done. RESULT: The male to female ratio was 3:2, and the average age at presentation was 39.7 years (range: 19-64years). The average time from injury to presentation was 19.98 months (range: 6-132months). The commonest bone involved was the humerus (18), followed by the femur (17), the Tibia (11), the ulna (5), and the radius (2). Osseous union was achieved in 44 patients (83%). There was no significant difference in incidence of osseous union among the various bones. It was observed that previous infection at the fracture site adversely affected osseous union. CONCLUSION: The management of nonunion in long bones by compression plating was found to be satisfactory. (+info)
Morphological and topographical anatomy of nutrient foramina in human upper limb long bones and their surgical importance.
(14/19)
OBJECTIVES: To study the morphology and topography of nutrient foramina and to determine the foraminal index of the upper limb long bones. MATERIALS AND METHODS: The study comprised 243 upper limb long bones, which included humeri, radii, and ulnae. The nutrient foramina were identified macroscopically in all the bones and an elastic rubber band was applied around these foramina. The bones were photographed with the digital camera and foramen index was calculated. Each bone was divided into five equal parts and was analyzed topographically. RESULTS: From our observations, 93.8% of the humeri had single nutrient foramen. The double foramen was observed in 3.1% of the cases and the foramen was found absent in 3.1% of the humeri. In case of radius, 94.4% had single foramen, 1.4% had double foramen, and in 4.2% of the cases it was absent. With respect to ulna, all the 75 bones had single foramen. The mean foraminal index was 57.6 for the humerus, 34.4 for both the ulna and radius. The majority (70%) of the foramina in humerus were located at the 3/5th part, 83.6% of the ulnae foramina at the 2/5th part and 87.7% of the radii foramina at the 2/5th part. CONCLUSIONS: The study has provided additional information on the morphology and topography of nutrient foramina in upper limb long bones. The knowledge about these foramina is useful in certain surgical procedures to preserve the circulation. As microvascular bone transfer is becoming more popular, a convention for the anatomical description of these foramina is important. (+info)
