Twenty-three cases of severeopen commiunted fractures of thetibia and fibula were treated byexternal skelatal fixation and skinflaps.The skin defects were repairedby the facio-cutaneous flaps, themusculo-cutanecus flap of the gast-rocnemius muscle or the vascularizedosteo-cutaneous flap of the ilium.Seventeen cases were followed-upfor an average of 13 months.Clinicalbony union was obtained in anaverage of 110 days. The authorsrecommended that it was a satisfact-ory method of traetment if a thoroughdebridment, reduction and fixation of the fracture by external skeletal fixation and repaire of wound and the skin defects by tissues flaps were carried out.
ObjectiveTo investigate the effectiveness of internal and external lysis combined with Ilizarov external fixation technology for severe knee pathological flexion contracture deformity in children.MethodsA retrospective analysis was made on 12 children (12 knees) with severe knee pathological flexion contracture deformity who were treated with internal and external lysis and Ilizarov external fixation between August 2012 and January 2017. There were 9 boys and 3 girls with an age of 3-12 years (mean, 8.4 years). There were 8 cases of tuberculosis, 3 cases of haemophilia A, and 1 case of residual deformity after extensive hemangioma drug injection. The disease duration ranged from 5 months to 4 years, with an average of 20.3 months. The degree of knee contracture was (67.42±23.30)°, and the range of motion of knee was (38.33±14.98)°. The preoperative Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score was 78.42±15.57. The complication was observed after operation, and the degree of knee contracture, range of motion, and WOMAC score at 3 months and 1 year after operation were recorded and compared with those before operation.ResultsThe operations completed successfully in all children. All the 12 cases were followed up 9-24 months (mean, 14.5 months). All incisions healed by first intention after operation. The knee function of all children improved significantly and the weight-bearing walking function of the lower limbs restored. The degree of knee contracture, range of motion, and WOMAC score were significantly improved at 3 months and 1 year after operation (P<0.05), but there was no significant difference between 3 months and 1 year after operation (P>0.05).ConclusionFor severe knee pathological flexion contracture deformity in children, application of internal and external lysis combined with Ilizarov external fixation has advantages, such as small trauma, rapid recovery, and early postoperative knee function training, and good effectiveness.
Objective To analyze the data of external fixation instruments (including Ilizarov instruments) used by QIN Sihe orthopaedic surgical team in the treatment of limb deformities in the past 30 years, and to explore the indications for the application of modern external fixation techniques in the correction of limb deformities and individual device configuration selection strategy. Methods According to QIN Sihe orthopaedic surgical team, the use of external fixator between January 1988 and December 2017 was analyzed retrospectively. The total use of external fixation and the proportion of different external fixators were analyzed in gender, different operation time, different age, different parts, and different diseases. Results External fixators were used in 8 113 patients, 69 of them were used simultaneously in both lower extremity surgery, so 8 182 external fixators were used. Among them, there were 4 725 (57.74%) combined external fixators, 3 388 (41.41%) Ilizarov circle fixators, 64 (0.78%) single arm external fixators (including Orthofix), 5 (0.06%) Taylor space external fixators. There were 4 487 males (55.31%) and 3 626 females (44.69%). According to the analysis of different time periods, the number of external fixators increased year by year, and the number of applications increased after 2000. The main age of the patients was 11-30 years old, of which 1 819 sets (22.23%) were used at the age of 21-25 years. The use of the external fixator covered almost all parts of the limbs, with the ankle and toe areas being the most common, reaching 4 664 sets (57.00%), and the upper extremities the least, with 152 sets (1.86%). The 8 113 cases covered more than a dozen disciplines and more than 150 kinds of diseases. The top 5 diseases were poliomyelitis sequelae, cerebral palsy, deformity of lower extremity after spina bifida, traumatic sequelae, and congenital equinovarus foot. Conclusion Ilizarov technique has been widely used in extremity deformity, disability, and complicated orthopedic diseases caused by vascular, lymphoid, nerve, skin, endocrine, and other diseases. The indication of operation is far beyond the scope of orthopedics. The domestic external fixator and its mounting tools can basically meet the requirements of various treatments. The technique of external fixation has entered a new era of tension tissue regeneration under stress control, natural repair of tissue trauma and deformity, and reconstruction of limb function.
ObjectiveTo observe the effectiveness of open release combined with distal radius fixation hinged external fixation for the treatment of elbow stiffness.MethodsA total of 77 patients with elbow stiffness caused by trauma were enrolled in this study between October 2014 and October 2015. The patients were divided into control group (39 cases) and observation group (38 cases) by random number table method. The patients in the observation group were treated with elbow joint opening and release combined with distal radial fixation hinged external fixation, while the control group was treated with traditional release. There was no significant difference in gender, age, disease causes, original damage diagnosis, the time from injury to operation, preoperative flexion and extension activity of elbow joint, and preoperative Mayo elbow joint function score between 2 groups (P>0.05). After operation, the function of elbow joint was evaluated by the flexion and extension activity of the elbow joint and the Mayo elbow joint function evaluation standard.ResultsThe incisions healed by first intention in 2 groups. In observation group, there were 1 case infection of nail tract, 2 cases ulnar nerve symptoms, 1 case elbow ossification, and 1 case moderate pain in the elbow; while in control group, there were 2 cases of infection of nail tract, 2 cases of ulnar nerve symptoms, and 3 cases moderate pain in the elbow. The patients in 2 groups were followed up 6 weeks to 12 months, with an average of 6 months. The flexion and extension activity of elbow joint and Mayo elbow joint function score at last follow-up were significantly improved when compared with preoperative ones (P<0.05); at last follow-up, the flexion and extension activity of elbow joint and Mayo elbow joint function score in observation group patients were significantly better than those in control group (P<0.05). According to the Mayo elbow function evaluation standard, the results were excellent in 27 cases, good in 10 cases, and fair in 1 case, with an excellent and good rate of 97.4% in observation group; and the results were excellent in 12 cases, good in 21 cases, fair in 4 cases, and poor in 2 cases, with an excellent and good rate of 84.6% in control group; showing no significant difference between 2 groups (P=0.108).ConclusionOpen release combined with distal radius fixation hinged external fixation can significantly improve the elbow function of patients with traumatic elbow stiffness, its recovery of elbow function was superior to the traditional release.
Objective To summarize the effect and complication of treatment for Pilon fracture using limited internal fixation combined with external fixation. Methods From April 1996 to June 2003, 20 patients with Pilon fracture were treated with limited internal fixation combined with external fixation as the treatment group and 22 patients with Pilon fracture with other methods as the control group. The X-ray films, clinical effect and complication were analyzed and compared between 2 groups. Results All cases were followed up for 8 to 26 months(15.2 months on average). According to Helfet’s criterion forclinical effect, the excellent and good rates were 75% in the treatment group and 72.7%in the control group, being no significant difference (Pgt;0.05). According to Burwell-charnley criterion for reduction, the X-ray film resultsshowed the excellent and good rates were 90% in the treatment group and 86.4% in the control group, being no significant difference (Pgt;0.05). But there was significant difference in complications between 2 groups (Plt;0.05). Conclusion Limited internal fixation combined with external fixation is better in resuming ankle joint function and remarkably reducing complication, especially in reducing soft tissue complication and collapse of bone joint; it is useful in the treatment of Pilon fracture.
Objective To review the methods of metacarpal and phalange lengthening and to point out the problems at present as well as to predict the trend of development in the field. Methods Domestic and abroad l iterature concerning the methods of metacarpal and phalange lengthening in recent years was reviewed extensively and thoroughly analyzed. Results At present, there are many methods to treat the short finger disabil ity, but the methods of metacarpal and phalange lengthening have an advantage, which include closed osteotomy lengthening, callus-lengthening, and modified Il izarovmethod. Each surgical method has its advantages and l imitations. However, the part of osteotomy, the length and speed, and the postoperative compl ications etc. have been disputed. Conclusion The modified Il izarov method has the advantages of simple operation, minimal invasion, and less compl ications, but the long-term results of each treatment method are unknown and need more further studies.
Objective To summarize the clinical application value and progress of Ilizarov technique in the treatment of foot and ankle trauma. MethodsThe related literature of Ilizarov technique in the treatment of foot and ankle trauma was extensively reviewed, and the fundamental principles of Ilizarov technique and its clinical application in the treatment of complex foot and ankle trauma such as Pilon fractures, lateral malleolus defects, calcaneal fractures, and talus fractures were reviewed, and its efficacy and complications were analyzed. ResultsThe Ilizarov technique demonstrates significant advantages in treating open fractures, bone defects, and cases with poor soft tissue conditions, achieving high rates of bone defect repair, effective infection control, and improved functional scores. However, complications such as pin tract infections remain notable. Conclusion The Ilizarov technique is an effective approach for managing complex foot and ankle trauma, particularly in high-risk cases. Its dynamic fixation mechanism combines mechanical stability with biological repair.
