  • VERTEBRAL PEDICLE SCREW-RODS SYSTEM FOR CORRECTING PARALYTICSCOLIOSIS

    Objective To explore some operative problems of correcting paralytic scoliosis(PS) by using vertebral pedicle screwsrods system. Methods From May 2000 to May 2005, 18 patients with PS were corrected by screwsrods system which were made of titanium alloy.There were 10 males and 8 females, aging from 11 to 26 years. The primary disease included poliomyelitis in 13 patients and myelodysplasia (MS) in 5 patients (2 cases for second correction) with scoliosis of an average 85° Cobb angle (55-125°). The pelvic obliquity was found in all patients with an average 24° angle (355°).Of the 18 patients,3 cases were given perioperative halo-pelvic traction, 2 cases were given vertebral wedge osteotomy and correction and fixation, the other patients were purely underwent the treatment of pedicle screwrods system implants. Fusion segment at operation ranged from 6 to 15 sections, applied screws the most was 16,the fewest was 6. Results There were no wound infections and neurologic complications, all wounds healed by the first intention. Allscoliosis obtained obvious correction (P<0.001), the correction rate averaged 52.95% (44%-81%); the majority of lumbar kyphosis and pelvic obliquity were apparently corrected. The average clinical follow-up (16 cases) was 21 months(6-36 months),there was no implants failure. One patient with MS had a worse Cobb magnitude, the other patients had no curve progression (P>0.05). Conclusion The use of vertebral pedicle screwsrods fixation to multiple vertebral bodys and short segment fusion for PS, the treatment method is reliable and the outcome is satisfactory. While performing the correcting operative procedures, the spinal, pelvic and lower extremity deformities and functions should be all considered as a whole.

  • RESEARCH PROGRESS IN LOWER LIMB LENGTHENING BY INTRAMEDULLARY NAIL

    ObjectiveTo summarize the research progress in the lower limb lengthening by intramedullary nail. MethodsThe domestic and foreign related literature about the lower limb lengthening by intramedullary nail was reviewed, summarized, and analyzed. ResultsThe intramedullary nail lengthening systems can be divided into 3 types:distraction by mechanical strength, by motorized electronic power, or by motorized magnetic force. The new technology has obvious advantages in complication incidence, limb function, bone healing rate, comfortable and cosmetic degree of the patients, and hospitalization days compared with the external fixation, but it also has the disadvantages including lengthening failure of system breakdown, intramedullary infection, injuries of vessel and nerve, limited distraction length, and expensive price of the apparatus. And the method also has several contraindications:narrow medulla, multiple curves of medulla, osteomyelitis, skin infection, and unclosed epiphyseal plate. ConclusionThe lower limb lengthening by intramedullary nail is a major improvement of Ilizarov technology. Although the method has been used in limited cases, the preliminary clinical results are excellent, and it can be regarded as a new trend of the limb lengthening, bone reconstruction, and deformity correction.

    ObjectiveTo investigate the effectiveness of Ilizarov technique in treatment of the clubfoot after burns.MethodsBetween March 2012 and February 2017, 12 patients (17 feet) with clubfoot after burns were treated with Ilizarov technique. There were 10 males (14 feet) and 2 females (3 feets) with an average age of 38 years (range, 18-52 years). There were 3 cases of left foot, 4 cases of right foot, and 5 cases of both feet. According to the Qin’s classification of clubfoot deformity, there were 5 feet of degreeⅠ, 9 feet of degreeⅡ, and 3 feet of degree Ⅲ.ResultsAll clubfeet were completely corrected without local skin necrosis, needle tract infection, or acroanesthesia. All patients could walk with a heavy load. Pationts were followed up from 4 months to 3 years (mean, 10 months). At last follow-up, according to the International Clubfoot Study Group (ICFSG) score, the effectiveness was rated as excellent in 7 feet, good in 7 feet, and fair in 3 feet, with the excellent and good rate of 82.4%.ConclusionUsing Ilizarov technique can gradually correct the clubfoot deformity with the advantages of minimal invasion, safeness, and simpleness.

  • Research progress of knee-salvage treatment for knee osteoarthritis

    Objective To review the progress of knee-salvage treatment based on the step therapy idea for knee osteoarthritis (KOA). Methods The domestic and foreign literature in recent years was searched, and the treatments of KOA at different stages were summarized and analyzed. Results The treatment of KOA is aimed at alleviating symptoms, delaying structural changes of joints, maintaining joint function, and improving quality of life. So the conservative treatment is still the first choice for KOA at early stage. Arthroscopic surgery can assist in the diagnosis and classification, simultaneously remove the intra-articular irritants, and limitedly repair the cartilage. Osteotomy is suitable for the KOA with abnormal lower extremity weight bearing line and articular line. And it can effectively balance the weight bearing stress of knee joint, improve the clinical symptom, and alleviate the progression of disease. Joint distraction can improve the mechanical environment of knee joint and repair the defect cartilage partly. With the technical development, unicompartmental knee arthroplasty (UKA) is back in fashion in recent years. It is a kind of real joint surface replacement, which is an important means of knee preservation method in patients with anterior medial KOA. Conclusion At present, there are many knee-salvage treatments based on the severity of the disease. Osteotomy and UKA are the most widely used and successful surgical techniques for knee preservation. However, the indications should be properly selected, and the surgeon should accumulate enough clinical experience. Otherwise, it is difficult to achieve good results.

  • Preliminary analysis of the clinical characteristics of 1 012 patients with secondary lower limb deformity of spina bifida from QIN Sihe Orthopedic Surgery Case Data between October 12, 1986 and December 31, 2020

    Objective To analyze the characteristics of patients with secondary lower limb deformity of spina bifida based on the QIN Sihe Orthopedic Surgery Case Data, and provide the references for clinical research, diagnosis, and treatment. Methods A clinical data of 1 012 patients with secondary lower limb deformity of spina bifida between October 12, 1986 and December 31, 2020 selected from QIN Sihe Orthopedic Surgery Case Data was retrospectively analyzed. Among them, 231 cases (22.83%) had undergone orthopedic surgery for lower extremity deformities in other hospitals. The gender, age at surgery, indicators related to spina bifida (deformity side, comorbidity, sensory disturbance level), and information related to surgery (operating time, surgical site, postoperative fixation method) were analyzed. Results Of the 1012 patients, 457 were males and 555 were females. The age was 3-51 years at the time of surgery, with a median of 18.0 years; among them, the 15-30 years old group had the most patients, accounting for 53.16%. Most deformities involved both lower limbs (652 cases, 64.43%). There were 111 cases of ulcers in the weight-bearing area of the foot, 265 cases of gatism, 554 cases of sensory disturbance, and 85 cases of abnormal hair on the waist. From 2010 to 2019, there were significantly more patients undergoing surgery than before 2010, reaching 61.17%. Sensory disturbances mostly occurred in the ankle and foot. A total of 1 149 sites were treated with surgery, of which the most ankle joint deformities were corrected by surgery, accounting for 84.33%. The main fixation methods after orthopedic surgery were external fixation, including Ilizarov external fixation (442 cases), combined external fixation (315 cases), and plaster fixation (189 cases). Conclusion Spina bifida can be secondary to severe deformities of the lower limbs, mainly in the ankles. Common complications include ulcers in the weight-bearing area, dysfunction of urine and feces, and sensory disturbances; external fixation is the main method of fixation after surgery.

  • Progress of remote-control intramedullary lengthening nail and its clinical treatment concept

    Ilizarov’s technology is an internationally recognized clinical treatment method for limb orthopedics, but there are many complications related to external fixation. With the development and progress of the times, the remote-control intramedullary lengthening nails had risen to prominence on the international stage as the second generation of orthomelic technology based on Ilizarov’s technology. Since the first remote-control intramedullary lengthening nail appeared in the 1980s, after more than 40 years of development, there are currently more than 3 types of extension mechanisms in remote-control intramedullary lengthening nails and a mature and stable clinical treatment model has been formed during the past long-term clinical treatment and experiments, such as the End-Point-First (EPF) program proposed by Professor Peter H. Thaller in Germany. Compared with Ilizarov’s technology, the remote-control intramedullary lengthening nail has obvious advantages in convenience, comfort, risk of infection, soft tissue injury, postoperative pain, and controllability of limb lengthening. This article mainly introduces the development and clinical treatment concept of remote-control intramedullary lengthening nail and the latest clinical treatment status of limb lengthening therapy abroad, hoping to provide new cognition and ideas for the further development of limb orthopedics in China.
