ObjectiveTo summarize the effectiveness and experience of Wanger grade 3-5 diabetic foot treated with vacuum sealing drainage (VSD) combined with transverse tibial bone transport.MethodsBetween March 2015 and January 2018, 21 patients with refractory diabetic foot who failed conservative treatment were treated with VSD combined with transverse tibial bone transport. There were 15 males and 6 females, aged 55-88 years (mean, 65 years). The diabetes history was 8-15 years (mean, 12.2 years). The duration of diabetic foot ranged from 7 to 84 days (mean, 35.3 days). The size of diabetic foot ulcer before operation ranged from 2 cm×2 cm to 8 cm×5 cm. According to Wanger classification, 8 cases were rated as grade 3, 11 cases as grade 4, and 2 cases as grade 5. Among the 21 cases, angiography of lower extremity before operation was performed in 5 cases, CT angiography of lower extremity in 16 cases, all of which indicated that the arteries below the knee were narrowed to varying degrees and not completely blocked. Preoperative foot skin temperature was (29.28±0.77)℃, C-reactive protein was (38.03±31.23) mg/L, leukocyte count was (9.44±2.21)×109/L, and the visual analogue scale (VAS) score was 6.8±1.5, and ability of daily living (Barthel index) was 54.3±10.3.ResultsAfter operation, 2 patients with Wanger grade 4 and smoking history failed treatment and had an major amputation (amputation above ankle joint) at 30 days and 45 days after operation, respectively. One patient with Wanger grade 5 and chronic heart failure died of cardiac arrest at 60 days after operation. The remaining 18 patients were followed up 6-24 months (mean, 9.2 months). The external fixator was removed at 40-62 days after operation, with an average of 46 days. All the wounds healed, with a healing time of 50-120 days (mean, 62.5 days). The pain of 18 patients’ feet was relieved obviously, and there was no recurrence of ulcer in situ or other parts. There was no complication such as tibial fracture and ischemic necrosis of lower leg skin after operation. After ulcer healing, the foot skin temperature was (30.86±0.80)℃, C-reactive protein was (22.90±18.42) mg/L, VAS score was 2.4±1.2, and Barthel index was 77.3±4.6, all showing significant differences when compared with preoperative ones (P<0.05); the leukocyte count was (8.91±1.72)×109/L, showing no significant difference (t=1.090, P=0.291).ConclusionVSD combined with transverse tibial bone transport can effectively promote the healing of Wanger grade 3-5 diabetic foot wounds, but smokers, unstable blood glucose control, and chronic heart failure patients have the risk of failure.
Objective To investigate the feasibility and effectiveness of ulnar cortex transverse transport technique in treating upper extremity thromboangiitis obliterans (TAO). MethodsA retrospective analysis was conducted on the clinical data of 7 male patients with upper extremity TAO who were admitted and met the inclusion criteria between January 2019 and July 2022. The patients ranged in age from 32 to 50 years, with a mean age of 40.1 years. The disease duration ranged from 6 to 24 months, averaging 13.6 months. The smoking history ranged from 8 to 31 years, with a mean of 18.4 years. All patients presented with finger ulcers or gangrene, including 1 case affecting the thumb and index finger, 1 case affecting the index and middle fingers, 1 case affecting the middle and ring fingers, 1 case affecting only the ring finger, and 3 cases affecting the ring and little fingers. The preoperative visual analogue scale (VAS) score was 9.1±0.7. All patients underwent treatment with the ulnar cortext transverse transport technique. The wound healing time and the disappearance time of rest pain were recorded. The VAS score was used to assess the degree of hand pain before and after operation. Serum interleukin 6 (IL-6) levels were measured before operation and at 1 month after operation. Computed tomography angiography (CTA) of the affected limb was performed before operation and at 3 months after operation to evaluate changes in blood vessels. The clinical outcomes were evaluated at 1 year after operation based on the Patwa and Krishnan grading system. ResultsAll 7 patients were followed up 12-17 months, with an average of 13.7 months. All patients experienced successful healing of ulcers, with wound healing time ranging from 14 to 21 days, averaging 17.3 days. During the follow-up, no complication occurred, and there was no recurrence of ulcers. The disappearance time of rest pain ranged from 8 to 15 days, averaging 12.1 days. The pre- and post-operative (1-month) serum IL-6 levels were (25.1±5.9) pg/mL and (11.9±2.9) pg/mL, respectively, with a significant difference (t=5.363, P=0.002). CTA examination at 3 months after operation revealed partial revascularization of upper extremity arteries and establishment of collateral circulation, showing significant improvement compared to preoperative status. The VAS scores at 1, 7, 28 days, and 6 months postoperatively were 6.4±0.8, 3.7±0.8, 0.6±0.8, and 0.1±0.4, respectively, all of which significantly improved compared to preoperative scores (P<0.05). Furthermore, the VAS scores gradually decreased over time, with significant differences observed between postoperative time points (P<0.05). At 1 year after operation, the effectiveness of all 7 patients were evaluated as excellent based on the Patwa and Krishnan grading system. ConclusionThe ulnar cortex transverse transport technique can improve blood circulation in the upper limb of patients with TAO, reconstruct microcirculation, inhibit inflammation, promote ulcer healing, and alleviate limb pain.
Objective To report the clinical experience of using Ilizarov wrist joint distraction technique in the treatment of a case of rheumatoid arthritis of the wrist. Methods In January 2019, a 49-year-old female patient with rheumatoid arthritis of the left wrist, complicated by ulnar impaction syndrome, was admitted for treatment. Preoperatively, the active range of motion of the left wrist was as follows: extension 0°-flexion 0°, pronation 65°-supination 35°, and grip strength of 4.0 kg. The visual analogue scale (VAS) score was 9, and the Cooney wrist function score was 15, indicating poor function. As conservative treatment failed to achieve symptom relief, Ilizarov wrist joint distraction surgery was performed. Postoperatively, joint distraction was applied at 2 mm increments on postoperative days 2 and 7, in 4 separate sessions. Results Postoperative X-ray film examination at 7 days revealed a distraction of 3.6 mm in the affected wrist joint compared to the contralateral side. The external fixator was removed 2.5 months postoperatively. At 22 months postoperatively, X-ray film and MRI examinations revealed that the joint space of the left wrist had returned to near-normal, with significant reduction in joint effusion and synovial proliferation. The active range of motion of the left wrist improved to extension 15°- flexion 30°, pronation 90°-supination 90°, with a grip strength of 18.0 kg. The wrist pain VAS score decreased to 0, and the Cooney wrist function score improved to 90, indicating excellent function. At 50 months postoperatively, follow-up X-ray film, MRI, and functional assessments showed the results similar to those at 22 months. Conclusion Ilizarov wrist joint distraction may be a viable treatment option for rheumatoid arthritis of the wrist.
【Abstract】 Objective To observe the effectiveness of limited operations and Ilizarov techniques for correction of congenital clubfoot (CCF) in adolescents, and to explore the new methods and new ideas for functional reconstruction of CCF. Methods Between September 2003 and July 2010, 25 adolescent patients (40 feet) with CCF were treated. Of the 25 patients, 14 were male (20 feet) and 11 were female (20 feet) with an age range from 12 to 25 years (mean, 15.7 years). The left feet were involved in 4 cases, the right feet in 6 cases, and both feet in 15 cases. According to Qin’s clubfoot deformity scale, 9 feet were rated as degree I, 17 feet as degree II, and 14 feet as degree III. In these cases, 9 feet were accompanied by internal rotation deformities of crus and 1 case by subluxation of right hip joint. After soft tissue release and osteotomy, 9 feet (degree I) were fixed by composite external fixation instruments, 31 feet by Ilizarov external fixation instruments. The deformity was corrected from 5 to 7 days after operation with distraction of 0.5-1.0 mm/d, then distraction stopped when the ankle was corrected at a hyperextension of 5 to 10° and light valgus. The affected limb might undergo weight bearing walking with external fixation at corrected position for 4 to 6 weeks. If one had both feet deformity, staged operation should be performed with a surgery interval of 3 to 6 months (mean, 4 months). Results The fixation time was 6-12 weeks (mean, 8 weeks) in 9 feet fixed by composite external fixation instruments, and it was 6-17 weeks (mean, 13 weeks) in 31 feet fixed by Ilizarov external fixation. All 25 patients were followed up 8 months to 6 years with an average of 37 months. During distraction process, slight pin track infection occurred in 6 cases (6 feet), which were cured after expectant management. One patient had recurrence of the deformity at 2 years postoperatively, who obtained satisfactory correction after Ilizarov external fixation for 4 weeks. The satisfactory correction and foot function were achieved in the other feet with walking on full weight-bearing. According to International Clubfoot Study Group (ICFSG) score, the results were excellent in 28 feet, good in 10 feet, and fair in 2 feet, with an excellent and good rate of 95% at last follow-up. Conclusion Combined limited operation with Ilizarov technique for correcting adolescent CCF is accord with biology principle and minimally invasive surgical principle, so it is a safe，minimally invasive, and effective method. It also can broaden the operative indications and correct degree III talipes equinovarus which is unattainable by traditional orthopedic surgery.
Objective To investigate the effectiveness of applying a standardized rehabilitation process in correction of adult clubfoot with the Ilizarov technique. Methods Thirty-eight adult patients who underwent orthopedic treatment with Ilizarov technique for clubfoot between August 2022 and December 2024 were retrospectively analyzed. The patients were divided into a study group and a control group with 19 cases in each group according to the different rehabilitation management processes and methods. The differences in baseline data such as gender, age, side, and preoperative Holden walking function grading between the two groups were not significant (P>0.05). In both groups, most of the clubfoot deformities were surgically corrected first, and the residual deformities were corrected by dynamic slow retraction with Ilizarov ring-type external fixation frame. The study group adopted standardized rehabilitation process management mode, including preoperative lower limb muscle strength training, postoperative pain and swelling management, weight-bearing management, gait and lower limb stability training. The control group adopted the conventional postoperative rehabilitation management mode. The occurrence of complications was recorded, including pin tract infection, ankle stiffness and pain, and deformity recurrence. Holden walking function grading was used to evaluate the walking ability of the patients. Clinical efficacy was evaluated by the QIN Sihe Deformity Correction Disability Repair and Functional Reconstruction Postoperative Efficacy Evaluation Scale. Patient satisfaction was evaluated by Likert score. Results Patients in both groups successfully completed surgery and rehabilitation and were followed up. The follow-up time ranged from 8 to 29 months, with a mean of 18.5 months. Among them, the follow-up time was (18.8±5.5) months in the study group and (18.2±5.7) months in the control group, and the difference between groups was not significant (t=0.316, P=0.754). The postoperative incidences of pin tract infection, ankle stiffness and pain, and deformity recurrence in the study group were 10.53%, 5.26%, and 5.26%, respectively, and in the control group were 21.05%, 36.84%, and 15.79%, respectively. And the difference between groups in the incidence of ankle stiffness and pain was significant (P=0.042). At last follow-up, both groups showed an improvement in Holden walking function grading compared to preoperative levels (P<0.05), and the grading of the study group was significantly higher than that of the control group (P=0.006). According to the QIN Sihe Deformity Correction Disability Repair and Functional Reconstruction Postoperative Efficacy Evaluation Scale, the grade difference between groups was not significant (P=0.089), and the excellent and good rates of clinical efficacy in study group and control group were 89.47% (17/19) and 73.68% (14/19), respectively. Patient satisfaction in study group was significantly better than that in control group (P=0.036). Conclusion Standardized rehabilitation process can effectively promote the postoperative functional recovery of adult clubfoot treated with Ilizarov technique, reduce the risk of complications and improve effectiveness.
ObjectiveTo investigate the effectiveness of the Ilizarov technique for the treatment of traumatic talipes equinovarus so as to provide the evidence for the clinical practice. MethodsBetween February 2011 and April 2012,42 patients with traumatic talipes equinovarus received treatment by Ilizarov technique,including 29 males and 13 females aged 17-55 years (mean,34.3 years).The left side was involved in 24 cases,and the right side in 18 cases.The disease duration was 6 months to 6 years (mean,2.7 years).According to the principles of Ilizarov,a ring external fixator was applied on the affected foot and lower leg.The threaded rods and screw nuts were revolved according to the tolerance of patients at 3-7 days after fixation.At first,forefoot varus or foot inversion was corrected,and then drooping feet deformity was corrected.The patients were encouraged to begin weight-bearing walking after correction.X-ray films were taken regularly to observe the ankle joint and avoid its dislocation.The external fixator was maintained in neutral position for 8-12 weeks after achieving satisfactory correction.An walking ankle-foot orthosis and a sleeping ankle-foot orthosis were used for more than 16 weeks after removal of the fixator.The outcome was assessed with American Orthopaedic Foot and Ankle Society (AOFAS) comprehensive scoring system and visual analogue scale (VAS) pain score. ResultsForty-two patients were followed up 14.3 months on average (range,10-24 months).All the patients achieved 0° dorsiflexion at 4-13 weeks (mean,6.8 weeks) after treatment with Ilizarov apparatus.The fixator was maintained for 10.7 weeks on average (range,10-16 weeks) after correction.No dislocation of the ankle joint and no damage to nerves and blood vessels occurred.The deformity of plantar flexion (10°) was found in 3 patients.At last follow-up,the patients could walk normally.AOFAS score was significantly increased to 93.4±8.0 from 52.7±10.1 at preoperation (t=-7.035,P=0.008);according to AOFAS scoring system,24 cases were grades as excellent,14 as good,2 as moderate,and 2 as poor,and the excellent and good rate was 90.5%.The VAS score of the foot significantly decreased to 3.51±1.44 from 7.55±1.39 at preoperation (t=-0.564,P=0.025). ConclusionIlizarov technique combined with non-fusion has satisfactory effectiveness in correction of traumatic talipes equinovarus.It is a safe,effective,and minimally invasive method.
ObjectiveTo compare the effectiveness using bone transport and bone shortening-lengthening by Ilizarov technique for tibial bone and soft tissue defects. MethodsBetween January 2004 and May 2012,31 patients with tibial bone and soft tissue defects were managed by Ilizarov technique,the clinical data were retrospectively analyzed.Bone transport was used in 18 cases (group A),and bone shortening-lengthening in 13 cases (group B).There was no significant difference in age,gender,type of fracture,defect location,size of bone and soft defects,and time from injury to operation between 2 groups (P>0.05).Postoperative complications were observed;Paley's criterion was used to assess the bone healing and function recovery of the limb. ResultsAll the flaps survived and healing of wounds by second intention was obtained in all cases of group A;healing of wounds by first intention was obtained in 1 case,delayed healing in 3 cases,and healing by second intention in 9 cases in group B.All patients were followed up 1.5-4.5 years (mean,2.4 years).Pin loosening or pin tract infection occurred in 15 cases of group A and in 10 cases of group B,and limb length discrepancy in 1 case of group B;there was no significant difference in the rate of complication (χ2=0.003,P=0.955).In the distracted zone,all fractures healed naturally with excellent scale.The healing time was (251±39) days in group A,and was (239±45) days in group B,showing no significant difference (t=0.800,P=0.430);the healing index was (4.26±0.19) d/mm in group A,and was (4.13±0.19) d/mm in group B,showing no significant difference (t=1.775,P=0.086).In the bone defect zone,natural healing was obtained in 12 cases and healing after second operation or bone grafting in 6 cases,with healing time of (341±55) days (excellent in 17 cases and good in 1 case) in group A;natural healing was obtained in 11 cases and healing after second operation or bone grafting in 2 cases,with the healing time of (295±62) days (excellent in 12 cases and good in 1 case) in group B;and there was significant difference in the healing time (t=2.195,P=0.036),but no significant difference in the healing scale (Z=-1.693,P=0.091).At last follow-up,the function recovery was excellent in 7 cases,good in 6 cases,and fair in 5 cases in group A,and was excellent in 3 cases,good in 6 cases,and fair in 4 cases in group B,showing no significant difference (Z=-0.660,P=0.509). ConclusionUsing bone transport or bone shortening-lengthening by Ilizarov technique for tibial bone and soft tissue defects,the overall outcomes are similar,but the healing of bone defect zone is faster when using bone shortening-lengthening.
Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
ObjectiveTo summarize the research progress of tibial transverse transport in the treatment of diabetic foot.MethodsThe domestic and foreign literature on the tibial transverse transport for diabetic foot in recent years was summarized, and the advantages and disadvantages of the technique were analyzed.ResultsThe tibial transverse transport was an innovation based on Ilizarov technique. At present, the treatment of diabetic foot by the tibial transverse transport is in the initial stage and has achieved good results, but there are also problems such as ulcer recurrence and re-fracture. And its biological mechanism to promote tissue regeneration, clinical technical points (such as the selection of incision and bone window size), the technical parameters of postoperative removal program, and the postoperative effectiveness are still in dispute and exploration. More clinical studies and practices are needed in the future to develop a standard protocol for this technique.ConclusionTibial transverse transport is a hot spot for microcirculation reconstruction of lower extremity. Significant progress has been made in the treatment of diabetic foot, which provides a new direction for limb salvage treatment. However, the technique is not mature, there are still many disputes and difficulties to be further studied clearly.
ObjectiveTo summarize the research progress of tibial transverse transport (TTT) in treatment of chronic ischemic diseases of the lower extremities.MethodsThe related literature was systematically searched and the mechanisms, clinical treatment methods, clinical efficacy, indications, contraindications, and complications of TTT were discussed.ResultsBased on the law of tension-stress, TTT is a new method in the treatment of chronic ischemic diseases of the lower extremities. It can relieve the ischemic symptoms, promote the wound healing, and increase the limb salvage rate. The clinical application in recent years has shown good effectiveness, and the scope of application is expanding.ConclusionDue to the current limited clinical application, the sample size of the TTT for the chronic ischemic diseases of the lower extremities is relatively small, and the follow-up time is limited. So its validity, long-term effectiveness, and bone transport standards are need further research.
