Objective To explore the effectiveness of computer-aided technology in the treatment of primary elbow osteoarthritis combined with stiffness under arthroscopy. Methods The clinical data of 32 patients with primary elbow osteoarthritis combined with stiffness between June 2018 and December 2020 were retrospectively analyzed. There were 22 males and 10 females with an average age of 53.4 years (range, 31-71 years). X-ray film and three-dimensional CT examinations showed osteophytes of varying degrees in the elbow joint. Loose bodies existed in 16 cases, and there were 7 cases combined with ulnar nerve entrapment syndrome. The median symptom duration was 2.5 years (range, 3 months to 22.5 years). The location of bone impingement from 0° extension to 140° flexion of the elbow joint was simulated by computer-aided technology before operation and a three-dimensional printed model was used to visualize the amount and scope of impinging osteophytes removal from the anterior and posterior elbow joint to accurately guide the operation. Meanwhile, the effect of elbow joint release and impinging osteophytes removal was examined visually under arthroscopy. The visual analogue scale (VAS) score, Mayo elbow performance score (MEPS), and elbow range of motion (extension, flexion, extension and flexion) were compared between before and after operation to evaluate elbow function. Results The mean operation time was 108 minutes (range, 50-160 minutes). All 32 patients were followed up 9-18 months with an average of 12.5 months. There was no other complication such as infection, nervous system injury, joint cavity effusion, and heterotopic ossification, except 2 cases with postoperative joint contracture at 3 weeks after operation due to the failure to persist in regular functional exercises. Loose bodies of elbow and impinging osteophytes were removed completely for all patients, and functional recovery was satisfactory. At last follow-up, VAS score, MEPS score, extension, flexion, flexion and extension range of motion significantly improved when compared with preoperative ones (P<0.05). Conclusion Arthroscopic treatment of primary elbow osteoarthritis combined with stiffness using computer-aided technology can significantly reduce pain, achieve satisfactory functional recovery and reliable effectiveness.
【Abstract】 Objective To summarize the current development of the correction of severe and rigid scol iosis. Methods Recent l iterature concerning the correction of severe and rigid scol iosis at home and abroad was extensively reviewed, and current developments of the correction of severe and rigid scol iosis were summarized. Results The correction of severe and rigid scol iosis shows developments as follows: the application of Halo-gravity traction increase and Halo-femoral traction is applied in posterior correction surgery. Fixation and correction technique with all pedicle screws was gradually popularized. The applications of posterior vertebral column resection, one-stage anterior and posterior surgery, and posterior-only correction surgery increase. Conclusion The developments of all kinds of correction techniques improve the correction effects of severe and rigid scol iosis. Now there is no standardized treatment protocol for severe and rigid scol iosis. Greater development can be expected in the future.
ObjectiveTo analyze the clinical characteristics of stiff left atrial syndrome (SLAS) after Mei mini maze procedure for atrial fibrillation (AF), and to explore its risk factors and treatments. Methods We retrospectively analyzed the clinical data of the patients who underwent Mei mini maze procedure in Xinhua Hospital between 2010 and 2020. According to whether SLAS occurred in the early postoperative period, patients were divided into a SLAS group and a non-SLAS group. The basic data, perioperative echocardiogram and laboratory test indexes of the two groups were compared. Results A total of 1 056 patients were collected. There were 672 (63.6%) males with an average age of 63.6±9.3 years, including 489 patients with persistent AF and 567 patients with paroxysmal AF. Fourteen (14/1 056, 1.3%) patients developed SLAS, with an average occurrence time of 2.1±1.1 days after the surgery. The average follow-up time of the whole group was 21.4±7.8 months. Two patients in the SLAS group developed SLAS again after discharge, and the occurrence time was 3 weeks and 4 weeks after the operation, respectively; while no SLAS occurred after discharge in the non-SLAS group. Diabetes and small preoperative left atrial diameter were risk factors for SLAS after surgery. Patients with SLAS had a good prognosis after adequate diuretic therapy. Conclusion The incidence of SLAS after Mei mini maze procedure for AF is low, and it mostly occurs in the early postoperative period. After adequate diuretic treatment, the prognosis is good.
OBJECTIVE: Extension stiffness of knee joint is always treated by the quadricepsplasty, but the main deficiency of this method is that patient feels weakness of lower limb and easily kneels down. The aim of this article is to explore the method to resolve the complications after quadricepsplasty. METHODS: Since 1978 to 1997, on the basis of traditional procedures of quadricepsplasty, sartorius muscle was used to reinforce the extension of knee joint. The lower 2/3 of sartorius muscle was fully dissociated only with its insertion intact. A tendon-periosteal-bone flap, about 2 cm in width, was managed on the anterior surface of patella, with its pedicle on the medial edge of patella. The tendon-periosteal-bone flap was used to fix the dissociated sartorious into patella to reinforce the extension of knee joint. The very lower part of sartorius was mainly aponeurosis, with the help of an aponeurosis bundle of iliotibial tract, it was fixed into the insertion of patellar ligament, through a bony tunnel chiseled adjacent to the insertion of patellar ligament. By now the movement of knee joint extension was strengthened by the transferred sartorius muscle. Postoperatively, every patient was required to extend and flex knee joint actively and/or passively. Altogether 12 patients were treated, 9 of them were followed up with an average of 14 months. RESULTS: The average movement was increased from 15 degrees to 102 degrees, and the average myodynamia was improved from grade II to grade IV. CONCLUSION: Traditional quadricepsplasty co-operated with transfer of sartorius muscle can strengthen the myodynamia of knee joint extension. It is simple method and can really achieve good function.
ObjectiveTo explore the role of increased preoperative ventricular-arterial stiffening in hypertensive infants with coarctation of the aorta (CoA).MethodsA retrospective study was conducted in 314 infants with CoA (CoA group, 193 males and 121 females, aged 5.4±2.2 months), and 314 infants receiving tumor chemotherapy with normal cardiovascular function and without pneumonia (control group, 189 males and 125 females, aged 4.4±3.8 months), who were admitted to our hospital from 2015 to 2017. The clinical data of the two groups were compared.ResultsThere were statistical differences in effective aortic elastance index (Eai), effective left ventricular end-systolic elasticity index (Eesi), ventricle-artery coupling index (VACi), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, and ratios of left ventricular hypertrophy, dilation and systolic dysfunction between the two groups (P<0.05). Compared with non-hypertensive CoA infants, CoA infants with hypertension had higher Eai, Eesi, NT-ProBNP level and proportion of left ventricular hypertrophy (P<0.05). Compared with concomitant ventricular septal defect, infants with isolated CoA had higher Eai, Eesi, NT-proBNP level, incidence of hypertension and higher proportion of left ventricular hypertrophy, dilation and systolic dysfunction (P<0.05). Eai and Eesi were positively correlated with NT-proBNP level, left ventricular hypertrophy and fractional shortening of left ventricle (P<0.05), while Eai and Eesi were negatively correlated with left ventricular end diastolic volume index, left ventricular end systolic volume index and concomitant ventricular septal defect (P<0.05). Hypertension was related to preoperative left ventricular hypertrophy, Eai, Eesi and NT-ProBNP. Eai was an independent risk factor for hypertension.ConclusionPreoperative ventricular-arterial stiffening is increased in infants with aortic coarctation, which is related to the occurrence of hypertension. Isolated CoA shows more significant increase in ventricular-arterial stiffening, higher ventricular overload and incidence of hypertension.
Objective To introduce operation skill of the spinal wedge osteotomy by posterior approach for correction of severe rigid scol iosis and to discuss the selection of the indications and the range of fusion and fixation. Methods Between July 1999 and January 2009, 23 patients with severe rigid scol iosis were treated with spinal wedge osteotomy by posterior approach, including 16 congenital scol iosis, 5 idiopathic scol iosis, and 2 neurofibromatosis scol iosis. There were 11 males and 12 females with a median age of 15 years (range, 8-29 years). Two patients had previous surgery history. The Cobb’s angles of scol iosis and kyphosis before operation were (85.39 ± 13.51)° and (56.78 ± 17.69)°, respectively. The mean spinal flexibil ity was 14.4% (range, 4.7%-22.5%). The trunk shift was (15.61 ± 4.89) mm. The preoperative CT or MRI showed bony septum in the canal in 2 patients. Results The mean operative time was 241 minutes and the mean blood loss was 1 452 mL. The average fused vertebrae were 10.7 segaments (range, 8-14 segaments). The follow-up ranged from 1 to 4 years with an average of 2 years and 6 months. The postoperative Cobb’s angle of scol iosis was (38.70 ± 6.51)°, the average correction rate was 54.7%. The postoperative Cobb’s angle of kyphosis was (27.78 ± 6.01)°, the average correction rate was 51.0%. The trunk shift was improved to (4.69 ± 1.87) mm, the increased height was 5.2 cm on average (range, 2.8-7.7 cm). The Cobb’s angle of scol iosis was (41.57 ± 6.80)° with an average 2.9° loss of correction at the final follow-up; the Cobb’s angle of kyphosis was (30.39 ± 5.94)° with an average 2.6° loss of correction at the final follow-up; the trunk shift was (4.78 ± 2.00) mm at the final follow-up. There were significant differences (P lt; 0.05) in the Cobb’s angles of scol iosis and kyphosis and the trunk shift between preoperation and postoperation, between preoperation and last follow-up. Four cases had pedicle fracture, 1 had L1 nerve root injury, 2 had superior mesenteric artery syndrome, 1 had exudates of incision, and 2 had temporary dysfunction of both lower extremity. Conclusion Spinal wedge osteotomy by posterior approach is a rel iable and safe surgical technique for correcting severe rigid scol iosis. With segmental pedical screw fixation, both the spinal balance and stabil ity can be restored.
Objective To discuss the surgical procedures and curative effect of stiff 2-5 metacarpophalangeal (MP) joints after crash injury in hand. Methods Between January 2006 and June 2009, 7 cases of stiff 2-5 MP joints were treated by releasing the stiff MP joints and reconstructing the function of lumbrical muscle in one stage. There were 6 males and 1 female with an average age of 32 years (range, 18-56 years). All injuries were caused by crash. Six cases suffered from multiple metacarpal fracture or complex dislocation of MP joint and 1 case suffered from complete amputation at level of middle palm of hand. The interval from initial wound heal ing to hospital ization was 3 to 15 months. Before operation, the X-ray films showed fracture healed and the results of nipping paper test were positive. All hands were treated with physical therapy for 1 month. After the plaster external fixation for 6 weeks, the physical therapy and function training were given. Results All wounds healed by first intention. The patients had no joint instabil ity and extensor tendon side-sl ipping with normal finger function. Six patients were followed up from 6 months to 3 years. The extension and flexion of MP joint were 0° and 67-90°, respectively. The average grip strength of injured dominant hand reached 86.70% of normal side and non-dominant hand reached 66.70% of normal side. The average injured dominant tip pinch strength reached 83.52% of normal side and non-dominant tip pinch strength reached 61.30% of normal side. Based on total active motion (TAM) system of Chinese Medical Association for Hand Surgery, the results were excellent in 4 cases, good in 1 case, and fair in 1 case; the excellent and good rate was 83.33%. Conclusion In patients with stiff MP joint and lumbrical muscle defect, releasing stiff MP joint and reconstructing lumbrical function in one stage can recover the function of MP joint and achieve good outcome. Physical therapy plays an important role before operation.
【Abstract】 Objective To investigate the clinical significances of the thoracic pedicle classification determined by inner cortical width of pedicle in posterior vertebral column resection (PVCR) with free hand technique for the treatment of rigid and severe spinal deformities. Methods Between October 2004 and July 2010, 56 patients with rigid and severe spinal deformities underwent PVCR. A total of 1 098 screws were inserted into thoracic pedicles at T2-12. The inner cortical width of the thoracic pedicle was measured and divided into 4 groups: group 1 (0-1.0 mm), group 2 (1.1-2.0 mm), group 3 (2.1-3.0 mm), and group 4 (gt; 3.1 mm). The success rate of screw-insertion into the thoracic pedicles was analyzed statistically. A new 3 groups was divided according to the statistical results and the success rate of screw-insertion into the thoracic pedicles was analyzed statistically again. And statistical analysis was performed between different types of thoracic pedicles classification for pedicle morphological method by Lenke. Results There were significant differences in the success rate of screw-insertion between the other groups (P lt; 0.008) except between group 3 and group 4 (χ2=2.540，P=0.111). The success rates of screw-insertion were 35.05% in group 1, 65.34% in group 2, and 88.32% in group 3, showing significant differences among 3 groups (P lt; 0.017). According to Lenke classification, the success rates of screw-insertion were 82.31% in type A, 83.40% in type B, 80.00% in type C, and 30.28% in type D, showing no significant differences (P gt; 0.008) among types A, B, and C except between type D and other 3 types (P lt; 0.008). In the present study, regarding the distribution of different types of thoracic pedicles, types I, II a, and II b thoracic pedicles accounted for 17.67%, 16.03%, and 66.30% of the total thoracic pedicles, respectively. The type I, II a, and II b thoracicpedicles at the concave side accounted for 24.59%, 21.13%, and 54.28%, and at the convex side accounted for 10.75%, 10.93%, and 78.32%, respectively. Conclusion A quantification classification standard of thoracic pedicles is presented according to the inner cortical width of the pedicle on CT imaging: type I thoracic pedicle, an absent channel with an inner cortical width of 0-1.0 mm; type II thoracic pedicle, a channel, including type IIa thoracic pedicle with an inner cortical width of 1.1-2.0 mm, and type IIb thoracic pedicle with an inner cortical width more than 2.1 mm. The thoracic pedicle classification method has high prediction accuracy of screw-insertion when PVCR is performed.
