ObjectiveTo study the feasibility of using propofol and remifentanil for reduction of shoulder joint dislocation in the conscious elderly patients, and compare its efficacy with brachial plexus block anesthesia. MethodsSeventy elderly patients (American Sociaty of Anesthesiologist physical statusⅠ-Ⅱ) who underwent shoulder dislocation reduction in our hospital between August 2011 and December 2013 were randomly divided into two groups, each group having 35 cases. Patients in group A received brachial plexus nerve block anesthesia downlink gimmick reset, while patients in group B received the use of remifentanil-propofol and lidocaine compound liquid intravenous drop infusion for anesthesia downlink manipulative reduction. After successful anesthesia, two groups of patients were treated with traction and foot pedal method (Hippocrates) to reset. We observed the two groups of patients in the process of reduction, and recorded their hemodynamic changes, reset time, discharge time, postoperative satisfaction, intra-operative memory, breathing forgotten (breathing interval was longer than 15 seconds) and visual analogue scale (VAS) scores, and then comparison was made between the two groups. ResultsPatients in both the two groups successfully completed manipulative reduction. Compared with group A, patients in group B had more stable hemodynamic indexes during the process of reduction, shorter reduction time, better anesthesia effect and higher postoperative satisfaction degree, and the differences were statistically significant (P<0.05). There was no significant difference in terms of time of leaving the operation room between the two groups (P>0.05). VAS score was higher in group A than that in group B (P<0.05). The occurrence of intra-operative memory amnesia and breathing forgotten phenomenon existed in part of the patients after operation in group B, but they did not occur in patients in group A. ConclusionRemifentanyl propofol-lidocaine compound fluid can be safely used in conscious elderly patients for shoulder joint dislocation reconstructive surgery, and it functions quickly with complete analgesia and stable hemodynamic indexes.
Objective To compare the effectiveness between minimally invasive plate osteosynthesis (MIPO) and open reduction and internal fixation (ORIF) for treatment of extra-articular distal tibial fracture. Methods Between March 2009 and March 2012, 57 patients with extra-articular distal tibial fractures were treated, and the clinical data were retrospectively analyzed. Of 57 cases, 31 were treated with MIPO (MIPO group), and 26 with ORIF (ORIF group). There was no significant difference in gender, age, cause of injury, type of fractures, complication, and time from injury to operation between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were compared between 2 groups. Results There was no significant difference in operation time and intraoperative blood loss between 2 groups (P gt; 0.05). Wound infection occurred in 5 cases [2 in MIPO group (6.5%) and 3 in ORIF group (11.5%)], showing no significant difference (χ2=0.651, P=0.499). The other wound obtained healing by first intention. All cases were followed up 13-24 months (mean, 15 months). No significant difference was found in the average healing time between 2 groups and between patients with types A and B by AO classification (P gt; 0.05); in patients with type C, the healing time in MIPO group was significantly shorter than that in ORIF group (t= — 2.277, P=0.033). Delayed union was observed in 3 cases of MIPO group (9.7%) and in 4 cases of ORIF group (15.4%), showing no significant difference (χ2=0.428, P=0.691). Mal-union occurred in 4 cases of MIPO group (12.9%) and in 1 case of ORIF group (3.8%), showing no significant difference (χ2=1.449, P=0.362). No significant difference was found in Mazur score between 2 groups (t=0.480, P=0.633). The excellent and good rate was 93.5% in MIPO group (excellent in 24 cases, good in 5 cases, fair in 1 case, and poor in 1 case) and was 92.3% in ORIF group (excellent in 18 cases, good in 6 cases, and poor in 2 cases), and the difference was not significant (Z= — 0.687, P=0.492). Conclusion Both MIPO and ORIF have good results in treating extra-articular distal tibial fractures. MIPO is superior to ORIF for treating complex and communited fractures.
ObjectiveTo analyze the treatment of Gartland type Ⅱ and Ⅲ supracondylar fracture of the humerus in children.MethodsBetween January 2015 and January 2017, 45 cases of Gartland type Ⅱ and Ⅲ supracondylar fracture of the humerus were treated. There were 28 boys and 17 girls with an age of 1-13 years (mean, 5.7 years). The causes of injury included sports injury in 43 cases and falling from height in 2 cases. Fractures were classified as type Ⅱ in 12 cases and type Ⅲ in 33 cases according to Gartland classification. The time from injury to operation was 2-12 hours (mean, 4.6 hours). All fractures were treated with closed reduction first, and 12 cases of Gartland type Ⅱ fracture were successful in closed reduction; 20 cases of Gartland type Ⅲ fracture were successful in closed reduction, 11 cases with reduction failure and 2 cases with radial nerve injury underwent assisted anterior transverse approach reduction. Then percutaneous crossed Kirschner wires fixation was performed.ResultsThe operation time was 16-52 minutes (mean, 32 minutes). The perspective frequency was 4-17 times (mean, 6.7 times). The hospitalization time was 3-7 days (mean, 4 days). All the 45 cases were followed up 8-20 months (mean, 12 months). The ulnar nerve paralysis occurred in 3 cases of Gartland type Ⅲ fracture that were treated with closed reduction, and recovered after 1-3 months. All fractures healed after operation, and the healing time was 2-3 months. No incision infection, Volkmann muscle contracture, and other complications occurred. The elbow joint function score at 6 months after operation showed that the results of closed reduction was excellent in 16 cases, good in 12 cases, and fair in 4 cases, with the excellent and good rate of 87.5%; in which Gartland type Ⅱ fracture was excellent in 9 cases and good in 3 cases, with an excellent and good rate of 100%, and Gartland Ⅲ was excellent in 7 cases, good in 9 cases, and fair in 4 cases with an excellent and good rate of 80%. The results of assisted anterior transverse approach reduction was excellent in 7 cases, good in 5 cases, and fair in 1 case, and the excellent and good rate was 92.3%.ConclusionGartland type Ⅱ and Ⅲ supracondylar fractures of the humerus can be treated with closed reduction or combined with the assisted anterior transverse approach reduction, then fixed by percutaneous crossed Kirschner wire, which is operational, smaller invasive, and less radiation exposure during operation, while postoperative function is good.
Objective To investigate the clinical significance of low dose corticosteroid applied in early period after lung volume reduction surgery（LVRS）. Methods From Apr. 2001 to Mar. 2004, 27 patients with chronic obstructive pulmonary disease were undergone video-assisted unilateral LVRS assisted with mini-incision in our department were retrospectively reviewed. According to whether dispensed with postoperative corticosteroid or not, patients were divided into corticosteroid group and non-corticosteroid group. Corticosteroid group received dexamethasone 10mg iv tid for 3 days and then declined to prednisone 5mg qd for 7 days. Both groups were measured and compared the quantity of thoracic drainage flow, duration of chest tube drainage, the time of air leaks and fever, and so on. At same time, blood gas analysis and blood routine test were performed at 1, 3, 7 and 30 d after operation. Results Corticosteroid and non-corticosteroid groups had no statistically differences in the air leaks time （P 〉 0.05）, but the quantity of thoracic drainage flow of corticosteroid group was lower than that of non-corticosteroid group evidently （700±210ml vs. 950±150ml, P = 0.001）. There was significant difference in average duration of chest tube drainage between both groups （9±3 d vs. 12±2 d, P = 0. 05）. Compared with non-corticosteroidgroup, PaO2 of corticosteroid group was higher at 1, 3d after operation （P〈0.05）. The amount of blood leukocyte of corticosteroid group was lower than that of non-corticosteroid group at 3, 7d after operation, there was no statistically significant in two groups （P 〉 0. 05）. At early period after surgery, both groups had no significant infection and death patient. Conclusion The low dose corticosteroid applied in early period after LVRS for short time（10 days in this research） could shorten the duration of chest tube drainage, decrease the quantity of thoracic drainage flow and the extent of inflammation in pleural cavity. In the mean time, this treatment does not increase the occurrence of significant complications during the early postoperative period, and there is no negative influence to the blood gas analysis.
Objective To precisely treat compl icated calcaneal fracture by 3D simulation through computer aid designed operation. Methods From November 2007 to March 2008, 38 patients of calcaneal fracture were treated. There were 29 males and 9 females aged 14-69 years old (average 29.8 years old). According to Sanders classification, there were 4 patients oftype I, 14 of type II, 12 of type III, and 8 of type IV. The time between injury and surgery was 3 hours to 5 days. The CT images of calcaneal fracture of 38 patients were put into computer for 3D reconstruction, then the Bouml;hler angles were measured and bone grafting angles were designed. According to the angle surveyed by the computer, the individual-oriented operation program was made, and then the operation was done under C-arm X-ray machine. Results The preoperative Bouml;hler angel was (34.58 ± 4.38)° in the normal side and (8.33 ± 12.62)° in the injured side, indicating there was significant difference (P lt; 0.05). During the process of the poking reduction by 3D simulation, when the bone rotating angle was (28.84 ± 6.51)°, the Bouml;hler angel was restored to (32.86 ± 1.72)°, indicating there was no significant difference when compared with the normal side before operation (P gt; 0.05), and significant difference compared with the injured side before operation (P lt; 0.05). Twenty-eight patients were followed up for 12-22 months (average 18 months). The Bouml;hler angel was restored to (32.41 ± 1.42)° 1 year after operation. According to the foot function scoring system made by American Ankle Surgery Association, 16 cases were graded as excellent, 10 as good, 1 as fair, 1 as poor, and the excellent and good rate was 92.9%. Conclusion Computer aid designed operation of compl icated calcaneal fracture by 3D simulation technique can restore the Bouml;hler angel and subtalar joint precisely. It is aneffective supplementary treatment method for calcaneal fracture.
ObjectiveTo investigate the efficacy and safety of over-bending rod reduction and fixation technique via posterior approach in the treatment of unstable fresh thoracolumbar burst fracture.MethodsA clinical data of 27 patients with unstable fresh thoracolumbar burst fracture, who were met the inclusive criteria and admitted between January 2018 and October 2019, was retrospectively analyzed. There were 15 males and 12 females with an average age of 41.8 years (range, 26-64 years). The fractures were caused by falling from height in 14 cases, traffic accident in 8 cases, and crushing by a heavy objective in 5 cases. The interval between injury and operation was 1-7 days (mean, 3.2 days). The injured fracture was located at T10 in 1 case, T11 in 3 cases, T12 in 6 cases, L1 in 7 cases, L2 in 7 cases, and L3 in 3 cases. According to AO classification, there were 11 cases of type A3, 7 cases of type B, and 9 cases of type C. Neurological function was rated as grade A in 3 cases, grade B in 7 cases, grade C in 5 cases, and grade D in 12 cases according to the American Spinal Injury Association (ASIA) grading. All cases were treated by over-bending rod reduction and fixation technique via posterior approach, and 16 cases were combined with limited fenestration decompression. The evaluation indicators consisted of operation time, intraoperative blood loss, the compression ratio of the anterior vertebral height, the invasion rate of the injured vertebra into the spinal canal, the Cobb angle of segmental kyphosis, visual analogue scale (VAS) score, and Oswestry Disability Index (ODI).ResultsThe operation time was 67-128 minutes (mean, 81.6 minutes), and the intraoperative blood loss was 105-295 mL (mean, 210 mL). All patients were followed up 12-23 months (mean, 17.2 months). A total of 178 pedicle screws were implanted during operation, and the accuracy of the implantation was 98.9% (176/178). The compression ratios of the anterior vertebral height at the early postoperatively and last follow-up were significantly increased when compared with preoperative one (P<0.05), and the invasion rate of the injured vertebra into the spinal canal, Cobb angle, VAS score, and ODI were significantly lower than those preoperatively (P<0.05). Except that the ODI at last follow-up was significantly lower than that of the early postoperative period (P<0.05), there was no significant difference between the last follow-up and the early postoperative period for other indicators (P>0.05). At last follow-up, the neurological function was rated as grade A in 1 case, grade B in 2 cases, grade C in 4 cases, grade D in 9 cases, and grade E in 11 cases according to the ASIA grading, showing significant difference when compared with that before operation (Z=–3.446, P=0.001).ConclusionOver-bending rod reduction and fixation technique can effectively restore vertebral height, reset the invaded vertebral block, and selectively perform limited decompression and posterolateral bone grafting to ensure the completeness of intravertebral decompression and stability, which is one of the effective methods to treat unstable fresh thoracolumbar burst vertebral fracture.
Objective To summarize the preliminary effectiveness of I.T.S. locking plate for intra-articular calcaneal fractures. Methods Between July 2010 and July 2011, 18 cases of intra-articular calcaneal fractures were treated. There were 10 males and 8 females with an average age of 46 years (range, 25-64 years). According to Sanders classification system, there were 3 cases of type II, 9 cases of type III, and 6 cases of type IV. The disease duration was 5-11 days (mean, 6 days). Open reduction and internal fixation with I.T.S. locking plate were performed via an L-shaped lateral extending incision. Results Superficial infection occurred in 1 case, and was cured after dressing changing; healing of incision by first intention was obtained in the other cases. Sixteen cases were followed up 14 months on average (range, 12-18 months). X-ray films demonstrated the bone union in all cases with an average union time of 12 weeks (range, 10-14 weeks). No implant failure or irritation of peroneal tendon occurred during follow-up. X-ray films showed subtalar post-traumatic arthritis with mild pain in 1 case at 11 months after operation, which was relieved by conservative treatment. At last follow-up, the Bouml;hler angle was improved from (12.9 ± 3.2)° preoperatively to (33.8 ± 4.0)° postoperatively, showing significant difference (t=22.78, P=0.00); the Gissane angle was improved from (83.6 ± 6.4)° preoperatively to (119.9 ± 8.5)° postoperatively, showing significant difference (t=17.02, P=0.00). The visual analogue scale (VAS) score was 1.3 ± 1.2, and the ankle and hindfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS) was 80.3 ± 7.9 at last follow-up. Conclusion Treatment of intra-articular calcaneal fracture with I.T.S. locking plate can obtain a stable fixation, which is a safe and effective method.
ObjectiveTo compare the effectiveness of minimally invasive percutaneous internal fixation and traditional open reduction via Henry approach and internal fixation in the treatment of unstable distal radial fractures.MethodsFifty-six patients with unstable distal radial fractures that met the selection criteria between October 2013 and December 2014 were randomly divided into minimally invasive group (26 cases) and traditional group (30 cases). They were treated with oblique T-shaped locking plate internal fixation via minimally invasive percutaneous approach or traditional Henry approach. There was no significant difference in gender, age, side, causes of injury, fracture classification, and time from injury to operation between 2 groups (P>0.05). The length of incision, operation time, intraoperative blood loss, hospitalization time, and fracture healing time were recorded in 2 groups. The difference of the length of the radial styloid process, the volar tilting angle, and the ulnar inclining angle between at 3 months postoperatively and preoperation were compared between 2 groups. The visual analogue scale (VAS) score, the percentage of the lateral wrist flexion and extension range, forearm rotation, and the hand grip strength (recorded as FS%, FR%, and HG% , respectively) were compared between 2 groups at 4 weeks and 3 months postoperatively. The wrist function was evaluated through the disability of arm-shoulder-hand (DASH) scores at 3 months postoperatively.ResultsThe length of incision, operation time, intraoperative blood loss, and hospitalization time in minimally invasive group were significantly less than those in traditional group (P<0.05). The incisions of 2 groups were all achieved primary healing. All patients were followed up 10-16 months (mean, 12.6 months). There was no radial artery injury, screw too long, or screw entering the joint space. In minimally invasive group, 1 patient had the symptoms of median nerve irritation after operation, and recovered completely at 1 month; in traditional group, there were 2 cases of tendon irritation after operation. There was no significant difference in the fracture healing time, the difference of the length of the radial styloid process, the volar tilting angle, and the ulnar inclining angle between at 3 months postoperatively and preoperation between 2 groups (P>0.05). At 4 weeks after operation, the VAS score in minimally invasive group was significantly less than that in traditional group, and the FS%, FR%, and HG% were significantly higher than those in traditional group (P<0.05). There was no significant difference in above indicators between 2 groups at 3 months after operation (P>0.05). The DASH score in minimally invasive group was significantly less than that in traditional group at 3 months after operation (t=–5.308, P=0.000). The patient’s aesthetic evaluation of postoperative wound in minimally invasive group was better than in traditional group.ConclusionFor treatment of unstable distal radial fractures, the metacarpal minimally invasive internal fixation has the advantages of smaller wound, incisional concealment, and quicker recovery of wrist joint.
ObjectiveTo explore the characteristics and treatment of intertrochanteric fracture, which the proximal part displaced forwardly and angularly.MethodsBetween March 2015 and March 2016, 40 patients with intertrochanteric fracture with forwardly and angularly displaced proximal part were treated with open reduction and intramedullary nailing fixation. There were 11 males and 29 females with the age of 56-87 years (mean, 75.7 years). The causes of injury included traffic accident in 1 case and fall in 39 cases. The body mass index was 18.9-33.8 kg/m2 (mean, 24.3 kg/m2). The time from injury to admission was 2-360 hours. The type of fracture according to AO-OTA classification was A1.2 type in 7 cases, A1.3 type in 1 case, A2.1 type in 6 cases, A2.2 type in 9 cases, A2.3 type in 12 cases, A3.2 type in 2 cases, and A3.3 type in 3 cases. The haemoglobin (Hb) value at admission and the lowest values before and after operation were recorded; the amount of transfused-blood during hospital stay and visible blood loss around operation were recorded. The short-form 36 health survey scale (SF-36) before injury and at 12 weeks after operation were recorded for evaluating the quality of living; the visual analogue scale (VAS) score at admission and at 2 days after operation were recorded for evaluating the degree of pain, the fracture union was evaluated by X-ray film and clinical examination, and the Harris hip scale were used to evaluate the injuried hip function at 12 weeks.ResultsThe lowest Hb value before operation was (99.10±16.48) g/L, which was significantly lower than that at admission［(114.33±14.93) g/L］(t=9.134, P=0.000). Eleven patients were treated with blood transfusion at amount of (520.00±269.98) mL before operation. The amount of transfused-blood during operation was (569.23±207.94) mL, and intraoperative blood loss was (373.08±154.68) mL. The lowest Hb value was (105.41±13.36) g/L after operation, and 8 patients were treated with second blood transfusion at amount of (500.00±185.16) mL. The reduction of fracture was rated as excellent in 16 cases, good in 18 cases, and poor in 6 cases according to the modified Baumgaertner criteria at 3 days after operation. Forty cases were followed up 12-15 weeks (mean, 12.8 weeks). No infection occurred. The VAS score at 2 days after operation was 3.2±0.5, which was significantly improved when compared with the value at admission (8.2±0.5) (t=37.500, P=0.000). At 12 weeks after operation, all the fractures healed; the Harris score was 82.5±6.9; and the SF-36 score was 51.4±11.5, which was significantly decreased when compared with the score before injury (54.9±11.5) (t=18.901, P=0.000). There were delirium in 4 cases, pneumonia in 8 cases, urinary infection in 5 cases, and venous thrombosis in 4 cases after operation. And all patients cured after corresponding treatment.ConclusionIntertrochanteric fracture with forwardly and angularly displaced proximal part is a type of unstable fracture, and it is difficult to reduction. It is necessary to achieve a good fracture reduction by means of auxiliary instrument. The anatomical alignment is the primary condition for the good effectiveness, and the anemia before and after the operation must be corrected.
Objective To summarize the morphological characteristics of sagittal beak-like deformity of head-neck fragment in femoral intertrochanteric fractures and to investigate the technical skills in fracture reduction. Methods A clinical data of 31 patients with femoral intertrochanteric fractures between May 2021 and April 2023 was retrospectively analyzed. The fractures had sagittal beak-like deformity of head-neck fragment in all patients. There were 13 males and 18 females, with an average age of 76.2 years (range, 68-83 years). The time from injury to operation was 36-76 hours (mean, 51.2 hours). Fractures were classified as type A1.2 in 10 cases, type A1.3 in 11 cases, type A2.2 in 6 cases, and type A2.3 in 4 cases according to the AO/Orthopaedic Trauma Association (AO/OTA)-2018 classification; and as type A1.3 in 10 cases, type A2.1 in 11 cases, type A2.2 in 6 cases, type A2.3 in 2 cases, and type A2.4 in 2 cases according to a novel comprehensive classification for femoral intertrochanteric fractures proposed by the “Elderly Hip Fracture” Research Group of the Reparative and Reconstructive Surgery Committee of the Chinese Rehabilitation Medical Association. Based on preoperative X-ray films, CT scan and three-dimensional reconstruction, the fractures were classified into two types: type 1 (14 cases), with uncomplicated fracture morphology, severe bone interlocking and (or) soft tissue incarceration; type 2 (17 cases), with severe fracture crushing, obvious dissociation between bone blocks, and severe soft tissue hinge destruction. After the failure of the closed reduction, all patients underwent fracture reduction assisted with instrument via anterior minimal incision and proximal femoral nail antirotation nails internal fixation. The operation time, intraoperative fluoroscopy, intraoperative visible blood loss, length of hospital stay, and incidence of complications were recorded. The fracture reduction quality and stability score were assessed at immediate after operation under fluoroscopy. The fracture healing was evaluated and healing time was recorded by X-ray films. The pain visual analogue scale (VAS) score was performed at 48 hours after operation and Parker-Palmer activity score at 3 months after operation for function evaluation. ResultsThe operation time was 39-58 minutes (mean, 46.3 minutes); fluoroscopy was performed 13-38 times (mean, 23.5 times) during operation; the intraoperative visible blood loss was 45-90 mL (mean, 65.3 mL). The fracture reduction quality and stability score were rated as good in 29 cases and acceptable in 2 cases. The pain VAS score was 2-6 (mean, 3.1) at 48 hours after operation. Eleven patients developed deep vein thrombosis of the lower limbs after operation. Patients were hospitalized for 6-10 days (mean, 7.3 days). All patients were followed up 5-8 months (mean, 6.5 months). All fractures healed at 3.5-8.0 months after operation (mean, 4.5 months). Parker-Palmer activity score at 3 months after operation was 9 in 28 cases and 6 in 3 cases. Conclusion The femoral intertrochanteric fracture with sagittal beak-like deformity of head-neck fragment is difficult to manually reduce. The pin combined with cannulated screw insertion to the neck cortex can hold the fragment and assist fracture reduction, which is a simple and effective technique.
