A 2-year-old male Suri alpaca was referred for evaluation of severe right forelimb lameness of 2 weeks' duration following a traumatic episode.
Examination of the distal aspect of the metacarpus revealed 4 wounds exuding purulent material. On weight bearing, the metacarpophalangeal joint was severely hyperextended with the palmar surface touching the ground. Ultrasonography of the palmar surface of the metacarpus revealed desmitis of the proximal suspensory ligament, a large core lesion of the deep digital flexor tendon at mid-metacarpus, and complete loss of fiber pattern within the deep digital flexor tendon and lateral aspect of the superficial digital flexor tendon distally.
The alpaca was treated systemically with antimicrobials and anti-inflammatory drugs and underwent repeated antimicrobial intraosseous regional limb perfusion. A bandage and splint were applied to stabilize the affected forelimb in an anatomically correct position, and the alpaca underwent prolonged stall confinement. At the time of hospital discharge 5 days after initial evaluation, clinical evidence of infection at the wound sites was absent. Three months following treatment, the alpaca was moving freely in a small paddock and had moderate hyperextension of the metacarpophalangeal joint.
Treatment of septic flexor tendonitis and suspensory desmitis with antimicrobial intraosseous regional limb perfusion in combination with systemic treatment with antimicrobials and orthopedic support resulted in an excellent outcome in this alpaca. Antimicrobial intraosseous regional limb perfusion is simple to perform and has the potential to be beneficial in the treatment of infections in the distal portion of a limb in camelids.
一只2岁的雄性苏利羊驼因创伤后持续2周的严重右前肢跛行前来接受评估。
掌骨远端检查发现4处伤口有脓性分泌物渗出。负重时，掌指关节严重过度伸展，掌面触地。掌骨掌面超声检查显示近端悬韧带腱炎、掌骨中部深层指屈肌腱有一个大的核心病变，以及远端深层指屈肌腱和浅层指屈肌腱外侧纤维结构完全消失。
羊驼接受了全身性抗菌和抗炎药物治疗，并反复进行抗菌性骨内区域肢体灌注。应用绷带和夹板将患侧前肢稳定在解剖学正确位置，羊驼被长时间圈养在厩舍。初次评估5天后出院时，伤口部位无感染的临床迹象。治疗3个月后，羊驼在一个小围场中自由活动，掌指关节有中度过度伸展。
在这只羊驼中，采用抗菌性骨内区域肢体灌注联合全身性抗菌治疗及矫形支持治疗化脓性屈肌腱炎和悬韧带腱炎，取得了极佳的效果。抗菌性骨内区域肢体灌注操作简单，对治疗骆驼科动物肢体远端感染可能有益。
