  • Discussion on dealing skills of complex soft tissue problems in osteomyelitis treated by Ilizarov technique

    Objective To discuss skills for the treatment of complex soft tissue problems in osteomyelitis using Ilizarov techniques. Methods The clinical data of 31 patients with complex soft tissue problems during the treatment of osteomyelitis with Ilizarov technique between January 2015 and June 2017 were retrospectively analyzed. There were 23 males and 8 females, with an age of 14-67 years (mean, 37.8 years). All the patients were post-traumatic chronic osteomyelitis, the disease duration was 12 days to 16 months (mean, 6.3 months). They went through 2-8 times surgeries (mean, 3.8 times). There were 29 cases of soft tissue insertion after bone grafting; 1 case of strephopodia and calcaneal osteomyelitis with plantar skin infection defect; 1 case of the open tibial fracture postoperative infection, the skin defect of infection was more than that of bone defect. The soft tissue defect area was 4.5 cm×4.0 cm to 16.5 cm×8.5 cm. Soft tissue depression and insertion was corrected by subcutaneous insertion of Kirschner wire after slow elastic retraction. Soft tissue defects were gradually resolved through slow traction. Results All patients were followed up 6-24 months (mean, 11.5 months). All wounds healed by first intention, and skin graft and flap repair were not performed in the two stage. One case of strephopodia and calcaneal osteomyelitis with plantar skin infection defect was treated with slow skin traction, no secondary suture was performed; no skin ulceration was found after walking for 3 months, and the feeling was slightly lower than normal. One case of soft tissue transverse traction wound completely covered, with no bone exposure and no obvious pigmentation of local soft tissue, the feeling was slightly lower than normal, the skin elasticity was worse than normal, and the color, temperature had no obvious abnormalities. There was no severe needle eye reactions in 29 patients with skin depressions corrected by Kirschner wire. Six cases of Kirschner wire showed elastic retraction and lacerate skin; 1 case of plantar skin traction had 2 times of exudation of the needle eye and local skin reddish phenomenon; the symptoms relieved when the traction needle was changed once, the traction was stopped for 1 week, the dressing was changed and antibiotics were used once. One patient with transverse traction had 3 times of pin-eye infection, and the treatment was completed after adjusting the traction device and symptomatic treatment. Conclusion For most of the complex soft tissue problems in osteomyelitis, early and effective intervention with Ilizarov technique can be easily, economically, and effectively solved, which provides a new way for clinical treatment.

  • Simultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique

    ObjectiveTo investigate the effectiveness of simultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique.MethodsBetween January 2014 and August 2020, 6 cases of traumatic calcaneal osteomyelitis with defect deformities were treated by simultaneous treatment of near-arc bone transport by Ilizarov technique. The patients were all male; aged from 40 to 61 years (mean, 49.3 years). The disease duration was 2-72 months, with an average of 16.1 months. All patients were traumatic calcaneal osteomyelitis, including 4 cases of falling from height, 1 case of traffic accident injury, and 1 case of crushing injury. The infection affected the talar-heel joint in 4 cases, and the talar-heel joint was fused or partially fused in 2 cases. After the external fixator was removed, the Maryland foot scoring system was used to evaluate the foot function, and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot function scoring system was used to evaluate the ankle-hindfoot function, and were compared with the preoperative scores.ResultsAll patients were followed up 1.5-26.0 months, with an average of 16.3 months. All incisions healed by first intention, no recurrence of infection occurred, and no surgical intervention such as second-stage bone grafting and fusion was performed. Five cases of calcaneal osteomyelitis with defect deformity underwent one-stage osteotomy and slipped, 1 case of the original bone mass after debridement after infection of calcaneal fractures slipped directly. The bone sliding time was 28-62 days, with an average of 38.7 days; the sliding distance was 3.1-5.2 cm, with an average of 3.6 cm. In 1 patient, due to the short follow-up time, the calcaneal slip bone had not healed, the external fixator had not been removed (not involved in clinical scoring), but the foot shape, reexamination of X-ray films and with frame walking were satisfactory. The time with external fixator was 6-8 months, with an average of 6.5 months in the other 5 cases. After removing the external fixator, the foot returned to three-point weight-bearing, and the longitudinal arch was recovered to varying degrees, and there was no obvious varus valgus. The Maryland score after removal of the external fixator was 80.8±4.7, which was significantly higher than that before operation (33.6±4.3) (t=–35.782, P=0.000), 3 cases were excellent and 2 cases were good; the median AOFAS ankle-hindfoot score was 84, the interquartile range was (79, 86), which was significantly improved when compared with the preoperative score [the median score was 33.5, the interquartile range was (21.3, 37.5)] (Z=–2.023, P=0.043), 4 cases were excellent and 1 case was good. Among them, pain, walking distance, getting rid of walking aids, going up and down stairs, deformity, etc. were significantly improved when compared with preoperative ones. Mobility such as subtalar and hock joints were poor or disappeared.ConclusionSimultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique can optimize the operation method, reduce the number of operations, and try to simulate the original shape of the calcaneus. It is an effective, economical, and novel treatment method.
