Objective  To investigate the efficacy of minimally invasive osteotomy with preservation of blood supply to the transversely transported bone segment in the treatment of chronic ischemic lower limb diseases using tibial transverse bone transport. Methods  A retrospective analysis was conducted on the clinical data of 12 patients with chronic ischemic lower limb diseases who met the selection criteria and were treated between June 2016 and December 2023. The cohort included 7 males and 5 females, aged 26-87 years (mean, 61.2 years). Among them, 7 patients had diabetic foot (DF), including 2 cases complicated by arteriosclerosis obliterans (ASO), with a DF duration ranging from 1.7 to 23.0 months (mean, 9.6 months) and ulcer sizes ranging from 3.2 cm×2.4 cm to 10.0 cm×6.6 cm. Three patients had ASO with a disease duration of 1.7-23.0 months (mean, 10.4 months) and ulcer or post-amputation wound sizes ranging from 2.2 cm×2.1 cm to 12.0 cm×7.7 cm. Additionally, 2 patients with thromboangiitis obliterans (TAO) had a disease duration of 7 and 12 months, respectively. Preoperatively, the mean foot skin temperature was (27.63±0.34)℃, and the visual analogue scale (VAS) score was 8.5±0.7. All patients underwent tibial transverse bone transport using minimally invasive osteotomy while preserving the blood supply to the transported bone segment. Postoperative complications and foot ulcer healing were observed. The effectiveness of tibial transverse bone transport was evaluated by comparing preoperative and postoperative foot skin temperature, VAS scores, as well as through CT angiography (CTA).Results  One DF patient with ASO was lost to follow-up, while the remaining 11 patients were followed up 10-29 months (mean, 20.5 months). One DF patient had a displaced fracture at the site of tibial transport due to trauma, which healed after plaster immobilization; 1 DF patient had a small amount of pigmentation in the skin of the donor site, but the blood circulation was good; no complication such as pin tract infection, skin necrosis, or osteomyelitis occurred in the donor site of all patients. At 2-3 weeks postoperatively, the foot skin temperature was (34.21±0.65)℃, and the VAS score was 0.3±0.1, both significantly improved compared to preoperative ones (t=?31.578, P<0.001; t=49.000, P<0.001). Two TAO patients experienced recurrent, persistent, intolerable pain at 7-10 days postoperatively, with no reduction in ulcer size or necrotic areas; 1 underwent toe amputation, and the other required a mid-leg amputation. The remaining patients achieved complete ulcer healing, with healing time ranging from 5.1 to 9.2 weeks (mean, 6.8 weeks). CTA showed no new vascular occlusions or embolisms. X-ray films at 4 months postoperatively demonstrated proper repositioning and good healing of the transported tibial bone segment. Conclusion The application of minimally invasive osteotomy with preserved blood supply to the transversely transported bone segment in tibial transverse bone transport for the treatment of chronic ischemic lower limb diseases effectively minimizes extensive soft tissue dissection, reduces surgical soft tissue damage, and better maintains local blood supply. This approach lowers the risk of postoperative infection and skin necrosis while accelerating postoperative recovery.
