Radiological and evaluation study of some mineral component to effect of median neuroectomy of the mid-shaft of metacarpal bone in fore-limb in donkeys

Abstract EN

The present study assigns the effect of neuroectomy to bone healing of experimentally induce bone fracture in 3rd metacarpal bone ,in donkeys by macroscopic, radiographic and evaluation of mineral levels(ca,p).

Sixteen donkeys of male sex with the age 1.5- 2 years, weighting 125-150 kg.

were was no callus or very little and the line of fracture is clear in radiogarphically examination and clinically .

The calcium mineral level was highly significant decrease in relation to time.

While The phosphors level were increase after 30th days and decrease on 60th days, The neuroectomized groups show decreased at the osteoblasts and increased of osteoclasts and the trabecular when compared with non- neuroectomized group with the aggregation of nests cells.

The conclusion of this study demonstrate the effectiveness of neuroectomized in delay bone healing and reduce the callus formation compared with non- neuroectomized group.

used for this study.

These animals were healthy clinically.

The donkeys were divided randomly into two groups( non- neuroectomized and neuroectomized) eight donkeys each group.

The animals anaesthetized with xylazine Hcl at dose 0.5 mg/kg.

B.W., then injectable Ketamine Hcl at the dose 3 mg/kg B.W.which administered intravenously.

The animals of non- neuroectomized group, induced one fracture at the mid of the shift of 3rd metacarpal bone.

Evaluated with clinical signs macroscopical, estimation of level of mineral and radiographic examination.

Gross examination swelling in the site of fracture and lameness.

The callus formation shows in radiographic examination.The calcium concentration was highly significant increase after 30th and 60th days , which the phosphorus level increase after 30th days and then s decrease at 60th days.

The neuroectomized group were median neuroectomy in right plexus forelimb ,and then after 30th days induce fracture in metacarpal bone in left side.

The right side neuroectomized cause paralysis and no ability to bear the weight and the site of fracture
