Objective:To investigate the application value of 3D MRI in the diagnosis of brachial plexus injuries combined with large vascular injuries.Methods:From June 2006 to December 2019, 55 patients with brachial plexus injuries were treated in our department. For 13 patients suspected of having vascular injuries, 3D MRI of brachial plexus and its accompanying blood vessels were performed simultaneously to understand the location and extent of nerve and blood vascular injury, so as to provide reliable evidence for accurate diagnosis and treatment. The application value of this imaging diagnostic technique in brachial plexus injury was evaluated by comparing with the intraoperative findings.Results:The brachial plexus and its accompanying blood vessels of 13 patients were reconstructed and digitally fused. The 3D MRI results of 7 patients who underwent surgery were consistent with the clinical examination and intraoperative findings.Conclusion:The 3D MRI simultaneous imaging of the brachial plexus and its accompanying vessels can clearly show the shape, location and injury of the brachial plexus and vessels, and show a three-dimensional relationship in anatomical structure, which is of great value in the diagnosis and treatment of brachial plexus injuries combined with adjacent vascular injuries.

Objective To analyze and evaluate the clinical efficacy of interphalangeal joint clearance,osteophyte resection,and cyst lesion exclusion surgery in the treatment of recurrent finger mucocele.Methods From January 2016 to February 2020,21 patients with recurrent finger mucocele were treated in our hospital.Among them,3 cases recurred after needle aspiration and injection of steroid hormones,5 cases recurred after cyst resection and local skin grafting repair,and 13 cases recurred after simple cyst resection.All patients were treated with interphalangeal joint clearance,osteophyte resection,and cyst lesion exclusion under brachial plexus block anesthesia.Only the collateral ligaments and extensor tendons on both sides of the interphalangeal joint were preserved,and the affected finger was fixed with a splint in the extension position for 3 weeks after surgery.The postoperative wound healing and recurrence of mucocele were followed up and observed,and the visual analog score(VAS)and range of motion(ROM)of interphalangeal joint were compared before and after surgery.Results All 21 patients had good postoperative incision healing.No infection,skin necrosis,and recurrence of cysts occurred.All patients were follow-up for 18 to 24 months,with an average of(21.0±1.9)months.The VAS of interphalangeal joint at the last follow-up(1.93±0.46)was significantly lower than that before surgery(3.07±0.83),and the difference was statistically significant(P<0.05).There was no significant change in the postoperative ROM(70.29±7.05)° of interphalangeal joint compared to preoperative ROM(69.60±5.40)°,and the difference was not statistically significant(P>0.05).Conclusion The application of interphalangeal joint clearance,osteophyte resection,and cyst lesion exclusion surgery to treat recurrent mucocele of the finger can avoid skin necrosis and cyst recurrence caused by cyst resection,and is a safe and effective treatment method.
Objective To explore the clinical efficacy of surgical treatment of carpal tunnel syndrome(CTS)caused by chronic synovitis.Methods From February to October 2022,our hospital underwent surgical treatment for 7 cases of carpal tunnel syndrome caused by chronic synovitis.During the surgery,the synovial lesion tissue was extensively removed,the transverse carpal ligament was completely released,and the excised specimens were sent for pathological,bacterial culture,and molecular biology testing.After the surgery,symptomatic treatments such as swelling reduction,pain relief,and nutrition were given.The clinical efficacy was evaluated based on the improvement of postoperative symptoms,whether synovitis recurred,and the improvement of pain.Results The pathological results showed synovial tissue hyperplasia and inflammatory cell infiltration.One case was confirmed astuberculous synovitis after surgery and received anti-tuberculosis treatment.The postoperative follow-up ranged from 6 to 14 months showed significant improvement in median nerve compression symptoms,no recurrence of synovitis,no local pain,and normal finger flexion and extension.Conclusions The surgical treatment for carpal tunnel syndrome caused by chronic synovitis has a satisfactory effect.The extensive resection of synovial lesion tissue and release of the median nerve during surgery are key to preventing recurrence and ensuring clinical efficacy.
Objective To explore the risk factors for wrist dysfunction 1year after internal fixation of distal radius fracture.Methods According to the inclusion and exclusion criteria,a retrospective analysis was conducted on the data of 183 patients with distal radius fractures who received volar locking plate internal fixation treatment in our department from October 2016 to October 2021.The PRWE score ≥20 after 1 year of fracture was used as the criterion for wrist joint dysfunction.Firstly,a chi square test was used to conduct a univariate test on relevant factors,and then factors with statistically significant diferences(P<0.05)were selected for multivariate logistic regression analysis to determine the independent risk factors for wrist joint dysfunction.Results The postoperative patients were follow-up for 12 to 18 months,with an average of 14.6 months.At the last follow-up,27 patients had wrist joint dysfunction,accounting for approximately 14.8%.The results of multivariate logistic regression analysis showed that TFCC injury,poor three-dimensional matching of the fracture end,and poor matching of the coronal bone structure were independent risk factors for wrist joint dysfunction in patients with distal radius fractures at 1 year after surgery.Conclusion The wrist joint dysfunction after surgery for distal radius fractures is the result of a combination of multiple factors.Orthopedic surgeons should comprehensively evaluate,scientifically prevent and treat,and improve the patient's functional prognosis during the diagnosis and treatment process.
Objective To report the clinical efficacy of 1.5 mm locking compression plate(LCP)for biplane fixation of comminuted proximal phalangeal fractures.Methods From January 2018 to December 2021,15 patients with comminuted proximal phalangeal fractures were treated by 1.5 mm LCP biplane fixation.X-ray films were reviewed at 4,12,and 24 weeks after surgery to assess fracture healing and measure the range of motion(ROM)of the healthy and affected sides of the patient's joints.At the last follow-up,total active motion(TAM)was used to assess finger function.Results All the patients were follow-up for 6 to 18 months,with an average of(9.3±2.4)months.All the fractures achieved anatomical reduction.The fracture healing time was 1.5 to 3.0 months,with an average of(2.1±1.1)months.There was no significant difference in the range of motion of the metacarpophalangeal and interphalangeal joints between the affected and healthy sides(P>0.05).At the last follow-up,according to TAM standard,the functional results were rated as excellent in 11 cases,good in 2 cases,and fair in 2 cases.All the patients had no nonunion,displacement,dysfunction,or deformity of the fracture.Conclusion The application of 1.5 mm LCP biplane fixation for comminuted proximal phalangeal fractures has a high fixation strength and low extensor tendon interference,which is conducive to early postoperative rehabilitation and exercise for patients,and can achieve satisfactory results.
Objective To report the clinical efficacy of absorbable suture assisted fixation in the treatment of elbow joint cartilage fractures.Methods The clinical data of 21 patients with cartilage fractures of the elbow joint admitted from June 2016 to March 2021 were retrospectively analyzed,including 1 case of dislocation of the elbow joint with fracture of the medial condyle of humerus and radial capitulum,6 cases of fracture of the radial capitulum with partial cartilage detachment,6 cases of fracture of the radial capitulum with fracture of the capitulum of humerus,3 cases of intra-articular fracture of the distal humerus,and 4 cases of dislocation of the elbow joint with fracture of the ulna coronoid process and the radial capitulum,1 case of fracture of ulna olecranon,radial capitulum and ulna coronoid process.All the patients were conducted by absorbable sutures to assist in the fixation of articular cartilage fracture blocks during surgery.After surgery,the elbow function was evaluated according to the Broberg-Morrey elbow function scoring standard,and the elbow flexion and extension activity and forearm rotation activity were recorded.Results All the patients were follow-up from 13 to 64 months with an average of 23 months.One patient underwent secondary arthrolysis due to ectopic ossification around the joint.One case had calcification of the medial collateral ligament and stiffness of the elbow joint.At the last follow-up,the average flexion of the affected elbow joint was 119.8°(90° to 140°),and the extension was-3.8°(-45° to 0°).The forearm pronation averaged 78.3°(46° to 84°)and supination averaged 79.6°(62° to 87°).The Broberg-Morrey score of the elbow joint was 59 to 95 points,with an average of 91.2 points.There were 12 excellent cases,8 good cases,and 1 poor case.Conclusion The repair of elbow joint cartilage fractures with suture fixation technology can maximize the preservation of articular cartilage integrity,and early joint functional exercise can achieve satisfactory results.
Objective To screen the optimal transfection efficiency and biocompatibility evaluation of nonviral vector nanospheres on primary tendon cells.Methods The nanospheres with different NP ratios were prepared.The tendon cells of chicken,rat,and mouse were performed primary culture and transfected with different doses of siRNA.And 12 hours after transfection,fluorescence photography and flow cytometry analysis were performed on the cells.CCK-8 was used to detect the viability of the cells after transfection for 24,48,and 72 hours,and WB was used to detect the expression level of GAPDH protein.Non transfected cells were used as negative controls,while liposomes were used as positive controls.Results For the three primary tendon cells of chicken,rat,and mouse,the transfection efficiency of liposomes significantly increased with the increase of transfection reagent dosage.The transfection efficiency of nanospheres did not significantly change,but the transfection efficiency of all nanospheres was higher than that of liposomes.Compared to liposomes,nanospheres have a greater cytotoxic response to cells,and the toxic effects gradually disappear over time.Conclusion Compared with liposomes,nanospheres have higher transfection efficiency for chicken,rat,and mouse tendon cells,and are ideal transfection reagents for siRNA in animal tendon cells.
Objective To report the early clinical efficacy of double incision closed reduction technique of TightRope for the treatment of Rockwood type Ⅲ to Ⅴ acute acromioclavicular joint dislocation.Methods From January 2019 to December 2021,31 patients with acute acromioclavicular joint dislocation were treated by double incision closed reduction technique of TightRope.According to the Rockwood classification,there were 5 cases of type Ⅲ,17 cases of type Ⅳ and 9 cases of type Ⅴ.The visual analogue score(VAS)and Constant-Murley score(CMS)were compared before and 6 months after the operation.Results All the patients were follow-up for 6 to 14 months,with an average of 7.94 months.All the incisions achieved primary healing,without complications such as coracoid process and clavicle fractures,and without loop plate detachment.The preoperative VAS was(6.29±0.46)points and 6 months after the operation the score was(1.19±0.40)points.Using Wilcoxon signed rank test,the difference between the two groups was statistically significant(P=0.001).The preoperative CMS was(39.65±2.54)points and 6 months after the operation the score was(91.45±1.84)points.Using paired t-test,the difference between the two groups was statistically significant(P<0.001).Conclusion The treatment of Rockwood type Ⅲ to Ⅴ acute acromioclavicular joint dislocation with double incision closed reduction technique of TightRope can achieve satisfactory functional recovery of the shoulder joint which is worthy of clinical promotion.

患者 男,54岁,农民.因发现左手中指逐渐增大肿物5年余,伴手指麻木半年余入院.患者5年前发现左手中指肿物,初始约绿豆大小,无活动受限、无感觉异常等不适症状,肿物逐渐增大,近半年来出现手指感觉麻木,偶有串电样疼痛不适,一直未予诊治,未曾自行穿刺、抽吸.
Objective To investigate the changes in contact stress of the distal radioulnar joint(DRUJ)after osteotomy of the metaphyseal shortening of the ulnar shaft through finite element analysis.Methods A healthy male volunteer was examined by CT scanning of his right upper limb in the neutral and pronation-extension positions respectively,and a three-dimensional finite element model of the wrist joint was established by a series of software,including Mimics Medical 21.0,Geomagic Design X and Ansys workbench 19.0.The simulated shortening osteotomy of 2,3,4 and 5 mm was performed on the ulnar metaphyseal.The contact stress on the DRUJ was analyzed under non-weight-bearing condition and a 100 N longitudinal stress load,and the results were expressed as cartilage equivalent stress nephogram and pressure data.Results In the neutral position,the maximum contact stress on DRUJ was distributed in the distal palmar region of the articular surface and increased gradually after 2 to 5 mm shortening osteotomy.The stress under the longitudinal load was consistent with that under non-load-bearing condition(2.460 to 5.842 MPa VS 2.152 to 5.765 MPa).In pronation-extension position,the maximum contact stress of DRUJ was distributed in the distal proximal dorsal region of the articular surface,which was greater than that in neutral position and gradually increased with the length of shortening osteotomy.The stress under longitudinal load was higher than that under non-weight bearing condition(11.620 to 24.658 MPa VS 7.652 to 19.273 MPa).Conclusion The contact stress of DRUJ increases gradually with the shortening of the metaphyseal end of the ulna after osteotomy.The maximum contact stress in pronation-extension position is higher than that in the neutral position,especially under axial stress,and the effect of axial load on the maximum contact stress of DRUJ in the neutral position is relatively small.
Objective To investigate the clinical efficacy of partial transposition of flexor carpi radialis tendon for multiple ligament reconstruction through a small incision in the treatment of first carpometacarpal joint dislocation.Methods From November 2019 to August 2022,7 patients with dislocation of the first carpometacarpal jointweretreated by cutting 1/2 of the flexor carpi radialis tendon and transposing it to reconstruct the dorsal ligament complex and anterior oblique ligament of the first carpometacarpal joint.After surgery,functional exercise was guided,and regular follow-up was conducted to compare the pain,daily life assessment,and joint function before and after treatment.Results All the patients were follow-up for 3 to 36 months,with an average of(14.7±12.0)months.Pain was evaluated using the visual analogue scale(VAS),with a preoperative score of 6.9±0.7 and the last follow-up of 1.0±1.3.The daily living condition was evaluated using Quick DASH score,with a preoperative score of 49.7±12.0 and the last follow-up of 11.4± 7.2.The joint function was evaluated using the Krimmer score,with a preoperative score of 45.7±13.7 and the last follow-up of 84.3±6.7.There were statistically significant differences in the results of preoperative and the last follow-up(P=0.002).At the last follow-up,there was no re-dislocation of the joint on the X-ray film.The postoperative pain of the patient was significantly relieved compared to that before the operation,and the life evaluation and joint function were significantly improved compared to that before the operation.Conclusion The application of partial transposition of flexor carpi radialis tendon through a small incision to reconstruct the dorsal and anterior oblique ligaments of the first carpometacarpal joint can improve joint stability,alleviate symptoms,improve joint function,and have minimal trauma,which is worthy of clinical application.
