“…[26][27][28] The fracture morphology reported for llamas and alpacas was mostly comminuted fractures, which differs from our results where only 16 of 58 fractures were multi-fragmentary. 26 Similar to impala, the most common fracture morphology in camels were simple fractures. 27,28 These two camel studies included fractures of the head, neck and mandible, which could have biased the results.…”

“…30 When the anatomically similar metacarpus and metacarpus were combined, they were the most commonly fractured long bones in goats, cattle, llamas and alpacas, as well as in our impala. 26,29,31 The diaphysis was reported to be the most commonly affected bone segment in llamas, alpacas and camels as in our study.

“…29 In another study, they found 53% of long bone fractures in llamas and alpacas affected skeletally immature patients. 26 One study done on young camels found more fractures in camels under 6 months of age, whereas another study found only 28% of fractures occurred in camels under 1 year of age. 27,28 Our study reported 40 of 58 long bone fractures occurred in skeletally immature patients; however, the low number of Salter-Harris type fractures recorded was unexpected.…”

“…Similar to our findings, the tibia is the single most commonly fractured long bone in llamas, alpacas and camels. [26][27][28] However, in a study in goats the metacarpus was reported the most commonly fractured long bone. 29 The femur was found to be the most commonly fractured long bone in goats in another study.…”

Objective The purpose of this study was to introduce a modified-Unger fracture classification in impala and report the findings of 58 long bone fractures classified according to this system. Methods This was a retrospective radiographical study evaluating 122 radiographs of 58 long bone fractures in 55 impala. The Unger fracture classification was modified and fracture illustrations for the metacarpal and metatarsal bones added. Each fracture was classified and assigned a four symbol α-numeric code using our classification. The patient signalment, skeletal maturity, fracture-associated soft tissue changes, presence of fissure lines, periosteal reaction and cause of the fracture were recorded. Results The overall fracture distribution based on location, found tibial (n = 17) fractures to be the most common fractured long bone. When combined, the majority of fractures involved the metacarpal and metatarsal bones (n = 23). Forty five of 58 fractures occurred in the diaphyseal bone segment. In all long bones, the distribution based on complexity was simple (n = 27), wedge (n = 16) and multi-fragmentary (n = 15) fractures. Thirty one of 58 fractures were open and fissure lines were detected in 20 of 58 fractures. Clinical Significance Our modified-Unger fracture classification was applicable in classifying 58 impala long bone fractures. This classification should provide the basis for further advances in veterinary and comparative ungulates, and particularly the antelopes, orthopaedics and traumatology.
