A 10-week-old male, Xoloitzcuintle (Mexican hairless dog), weighing 8.9 kg was presented after its owner accidentally stepped on its paw. The dog presented with acute pain, inflammation and grade IV lameness in the right hind paw. A complete transverse fracture in the right proximal tibia was diagnosed from radiography. The dog underwent a minimally invasive plate osteosynthesis (MIPO) procedure. After surgery, photobiomodulation therapy combined with static magnetic field (PBMT-sMF) was applied twice daily for 21 days. A multi-wavelength PBMT-sMF device was applied at three sites using different frequencies: proximal and distal of the fracture zone (3000 Hz, 40.35 J per site, and 300 s per site) and in the fracture zone (250 Hz, 39.11 J and 300 s per site). Follow up radiographies were performed after surgery and treatment with PBMT-sMF. Eighteen days post-surgery the healing process of bone was advanced. Fifty-five days post-surgery the callus was enlarged. In addition, radiographic union and clinical union was evidenced by closure of the fracture gap. This case report has reported the use of PBMT-sMF in order to accelerate and improve bone healing following a MIPO procedure on a complete transverse fracture in the proximal tibia of a puppy.
一只 10 周大的雄性 Xoloitzcuintle（墨西哥无毛犬），体重 8.9 公斤，在其主人不小心踩到它的爪子后被带到医院。这只狗表现出急性疼痛、炎症和右后脚四级跛行。通过放射学检查诊断为右胫骨近端完全横断骨折。这只狗接受了微创钢板接骨术（MIPO）。手术后，每天两次应用光生物调节疗法联合静磁场（PBMT-sMF）治疗 21 天。使用不同频率的多波长 PBMT-sMF 设备在三个部位进行治疗：骨折区域的近端和远端（3000 Hz，每个部位 40.35 J，每个部位 300 s）和骨折区域（250 Hz，每个部位 39.11 J 和 300 s）。手术后和 PBMT-sMF 治疗后进行了随访放射学检查。手术后 18 天，骨的愈合过程进展。手术后 55 天，骨痂增大。此外，通过骨折间隙的闭合证实了影像学和临床愈合。本病例报告介绍了在幼犬胫骨近端完全横断骨折的 MIPO 手术后，应用 PBMT-sMF 以加速和改善骨愈合。
