[Plastic and reconstruction surgery for non-healing wound after posterior spinal surgery].

OBJECTIVE

To investigate the clinical significance of different plastic surgeries in the treatment of poor healing wound after posterior spinal internal fixation.

METHODS

In this study, 16 patients with poor incision healing after posterior spinal internal fixation were retrospectively included, and dif-ferent plastic surgery treatment plans were determined according to the wound characteristics and defect condition. The measures included debridement, vacuum sealing drainage (VSD), and different tissue flaps according to the location and extent of the defect.

RESULTS

A total of 16 patients meeting the criteria were included, of whom 3 were treated with debridement combined with VSD and wound suture directly, 6 were treated with debridement combined with Z-flap for wound repair, 1 was treated with bilateral sacrospinous muscle flap for dural defect repair combined with Z-flap for skin wound repair, 1 was treated with lectus dorsi flap for wound repair, 3 were treated with the fourth lumbar artery perforator flap for wound repair. The wound was repaired with local rotating flap in 1 case and gluteus maximus musculocutaneous flap in 1 case. Among the 16 patients, 7 cases were positive for wound culture, including 3 cases of , 1 case of , 1 case of , 1 case of , 1 case of , and the other 9 cases were negative. After surgery, there were 7 patients with different degrees of poor wound healing, including 3 patients undergoing dressing change, 2 patients undergoing secondary debridement and suture, 1 patient undergoing free scalp skin graft, and 1 patient undergoing local effusion suction treatment. All the above 7 patients were discharged from hospital after improvement, and the remaining 9 patients had good first-stage wound hea-ling after surgery. None of the 16 patients underwent internal fixation.

CONCLUSION

Multiple factors could lead to poor wound healing after posterior spinal internal fixation. Early intervention, thorough debridement, removal of necrotic/infected tissue, and selection of suitable skin flap for effective wound fil-ling and covering were important means to ensure wound healing after spinal surgery and reduce removal of internal fixation.
