  • REPAIRING CHRONIC OSTEOMYELITIS COMPLICATED BY LONG BONE DEFECT INTIBIA WITH FREE SEGMENTEDFIBULA TRANSPLANTATION

    Objective To probe the repair method and effect of freesegmented-fibula transplantation to treat chronic osteomyelitis complicated by long bone defect in tibia in the first intention. Methods From March 1996 to December 2003, 67 cases of chronic osteomyelitis complicated by long bone defect were reconstructed with vascularized fibula graft after the long inflammable bone and soft tissue focus were resected. Their age ranged from 8 to 42 years. The course of disease was 6 months to 8 years. There were 14 cases of hematogenous osteomyelitis and 53 cases of traumatic osteomyelitis. Of them, 18 cases complicated by fracture of fibula; 21 cases by defect of skin ( 2 cm×4 cm-4 cm×10 cm) and bone exposure;53 cases by pathological fracture and nonunion; and 46 cases by 1-3 fistula of osteomyelitis. The length of bone defect was from 8 cm to 22 cm(mean 12 cm), andthegermiculture results of all cases were positive. Forty-six cases were treated with vascularized fibula graft, the other 21 cases with the skin flap. The segmentedfibula was 10-28 cm, skin flap size was 4 cm×7 cm6 cm×12 cm. Results After a follow-up of 12-45 months, the healing rate of sinus was 93.5% while the 6.5% remainders healed by the second sinus cleaning-up. The graft bone healed after 4-6 months(mean 4.2 months) by X-ray examination. The limb inflammation was controlled after 2 weeks.All 21 skin flaps all survived and the function recovery of affectedlimb was 79% of normal limbs according to Enneking evaluation system, but 2 patients occurred secondary fracture. The act or process of augmenting of tibia under 18-year-old cases were sooner than those who were more than 18-year-old. Conclusion It is a choice to repair the chronic osteomyelitis complicated by longbone defect with vascularized fibula graft in the first intention. The operation to reconstruct long bone defect is a good method to control inflammation efficiently, shorten period of treatment and reduce the time of operation.

  • Combination Ilizarov technique with tibiotalar or tibiocalcanean arthrodesis for one-stage treatment of ankle joints infection and bone defects

    Objective To evaluate the effectiveness of Ilizarov technique and tibiotalar or tibiocalcanean arthrodesis for one-stage treatment of ankle joints infection and bone defects. Methods Between January 2014 and April 2016, 14 patients with ankle joints infection and bone defects were treated by Ilizarov technique and tibiotalar or tibiocalcanean arthrodesis for one-stage. There were 12 males and 2 females with an average age of 39.8 years (range, 25-61 years). The causes of ankle infection included falling from height injury in 5 cases, falling injury in 4 cases, traffic accident injury in 1 case, crushing injury in 1 case, sprain injury in 1 case, and hematogenous reason in 2 cases. All the patients received surgery for 0-8 times (mean, 3.7 times) before admission. The modified American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score was 30.25±3.54 before operation. The disease duration was 1-30 months (mean, 10.3 months). Results All the incisions healed by first intension without recurrence of infection, and two-stage bone grafting operation did not performed. One case felt slight local pain and swell of ankle joint after weight-bearing walking more than 30 minutes, and without special treatment. All the patients had different degree skin redness and swelling of Kirschner wire pinhole for 0-3 times, and relieved after symptomatic treatment. All the patients were followed up 6-27 months (mean, 16.8 months). Except for 2 cases who did not remove the external fixator (with external fixation time of 6 months and 8 months respectively), the other patients removed the external fixator at 6-14 months (mean, 9 months) after operation, all patients recovered the walk function and without ankle pain. The modified AOFAS ankle and hindfoot score after removal of external fixator (70.92±1.0) was significantly higher than preoperative one (t=–10.992, P=0.000). Conclusion It is a simple and effective method for one-stage treatment of ankle joints infection and bone defects by Ilizarov technique and tibiotalar or tibiocalcanean arthrodesis.

  • 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.

  • Application of modified keystone flap in repairing of skin and soft tissue defect around joint

    ObjectiveTo explore the effectiveness of keystone flap in repairing skin and soft tissue defects around joint.MethodsBetween March 2013 and December 2017, 10 patients of skin and soft tissue defects around the joint were repaired with keystone flaps. There were 6 males and 4 females. The age ranged from 17 to 72 years, with an average age of 57.5 years. The skin and soft tissue defects located around the joints, including 2 cases of hip joints, 4 cases of knee joints, 3 cases of elbow joints, and 1 case of wrist joint. The cause of skin and soft tissue defects included scar contracture in 3 cases, basal cell carcinoma in 3 cases, squamous-cell carcinoma in 3 cases, and dermatofibrosarcoma protuberant in 1 case. The area of defects ranged from 4 cm×3 cm to 11 cm×11 cm. The keystone flap was designed beside the wound, and the V-shaped flap was designed at the longer side of the fan-shaped flap. The area of flap ranged from 7 cm×3 cm to 35 cm×10 cm. The flap was constantly compressed by vacuum assisted closure after operation for 3-6 days.ResultsPrimary wound healing was achieved and the flaps survived. All patients were followed up 6-24 months (mean, 15 months). The texture and color of flap was similar to the adjacent area. The appearance and function of joint were satisfactory.ConclusionThe keystone flap is a feasible and efficient way to repair the wound around joint. Furthermore, the skin color and texture is similar to the surrounding tissue after healing.

  • Clinical study of calcium phosphate cement loaded with recombinant human bone morphogenetic protein 2 combined with calcium phosphate cement loaded with antibiotic for chronic osteomyelitis with bone defect

    ObjectiveTo compare the effectiveness of calcium phosphate cement (CPC) loaded with recombinant human bone morphogenetic protein 2 (rhBMP-2) combined with CPC loaded with antibiotic versus CPC loaded with antibiotic alone in one stage for chronic osteomyelitis with bone defect.MethodsA single-blind prospective randomized controlled clinical trial was conducted. Between April 2018 and April 2019, 80 patients of chronic osteomyelitis with bone defect in accordance with the random number table were randomly divided into two groups, 40 in the trial group (CPC loaded with rhBMP-2 combined with CPC loaded with antibiotic) and 40 in the control group (CPC loaded with antibiotic). There was no significant difference in gender, age, disease duration, lesion, and preoperative white blood cells (WBC) count, platelet count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) between the two groups (P>0.05). All patients were implanted the corresponding CPC and external fixator after lesion clearance in the two groups. The postoperative WBC count, platelet count, ESR, CRP, hospital stay, cure rate of osteomyelitis, repaired bone defect volume, the time of external fixator removal, and the time of full weight-bearing of the affected limb were compared between the two groups.ResultsAll patients were followed up 12-24 months, with an average of 18.4 months. There was no significant difference in WBC count, platelet count, ESR, and CRP between the two groups at 4 weeks after operation (P>0.05). There were significant differences in WBC count, platelet count, and CRP in the two groups between 1 week before operation and 4 weeks after operation (P<0.05). And the ESR showed no significant difference between pre- and post-operation in the two groups (P>0.05). In the trial group, the anaphylactic exudate occurred in 1 patient with tibial osteomyelitis and the incision healed after oral administration of loratadine. The incisions of other patients healed by first intention in the two groups. One case of distal tibial osteomyelitis recurred in each group, and 1 case of humeral osteomyelitis recurred in the control group. The cure rates of osteomyelitis were 97.5% (39/40) in the trial group and 95% (38/40) in the control group, showing no significant difference between the two groups (χ2=0.000, P=1.000). There was no significant difference in the repaired bone defect volume and hospital stay between the two groups (P>0.05). X-ray film and CT showed that the bone defects were repaired in the two groups. The time of external fixator removal and the time of full weight-bearing of the affected limb were significantly shorter in the trial group than in the control group (P<0.05).ConclusionApplication of CPC loaded with rhBMP-2 and antibiotic in one stage is effective for the chronic osteomyelitis with bone defect, which can accelerate the bone regeneration in situ to repair bone defect, reduce the trauma, shorten the course of treatment, and obtain good function of the affected limb.
