ABSTRACT
Objective:To compare the efficacy of lateral elbow dislocation approach with non-dislocation approach for open reduction and internal fixation of distal humeral coronal fracture.Methods:A retrospective cohort study was used to analyze the clinical data of 26 patients with distal humeral coronal fracture admitted to Qilu Hospital (Qingdao) of Shandong University from January 2018 to October 2021, including 10 males and 16 females, aged 15-80 years [(51.6±4.9)years]. According to Dubberley classification, there were 10 patients with type 2A, 5 with type 2B, 6 with type 3A and 5 with type 3B. Overall, 12 patients were operated via lateral elbow dislocation approach (dislocation approach group) and 14 via lateral elbow non-dislocation approach (non-dislocation approach group). The operation time, intraoperative bleeding volume, incision healing, three-dimensional CT assessment of the reduction within one week after surgery (separation or step>2 mm as poor), Mayo elbow performance score (MEPS) at 3 months after surgery and fracture healing at the last follow-up were recorded in both groups. Complications were also compared between the two groups.Results:All patients were followed up for 3-18 months [(10.5±3.3)months]. The operation time was (146.9±15.5)minutes in dislocation approach and (122.7±11.1)minutes in non-dislocation approach group ( P>0.05). The intraoperative bleeding volume was (113.3±9.7)ml in dislocation approach and (112.9±10.1)ml in non-dislocation approach group ( P>0.05). All incisions healed uneventfully in stage I. All patients had good reduction in dislocation group, while only 7 patients had good reduction and the other 7 patients presented a separation or step>2 mm in non-dislocation group ( P<0.05). The MEPS was (90.0±1.4)points in dislocation approach group at 3 months after surgery, including 9 patients being rated as excellent and 3 good, with the excellent and good rate of 100%. In constrast, the MEPS was (78.9±2.9)points in non-dislocation approach group at 3 months after surgery, including 5 patients being rated as excellent, 4 good, 4 fair and 1 poor, with the excellent and good rate of 64.3% ( P<0.05). All fractures were healed at the last follow-up. In non-dislocation approach group, osteoarthritis occurred in 7 patients, including 3 with screw protrusion, 2 with heterotopic ossification and 2 of advanced age with osteophyte formation around the joint. In dislocation approach group, osteoarthritis occurred only in 2 patients of advanced age, showing osteophyte formation around the elbow joint, with no screw cutting or heterotopic ossification. Conclusion:For distal humeral coronal fracture, the lateral elbow dislocation approach is able to provide complete exposure of the articular surface, obtain anatomic reduction, restore elbow function and reduce complications when compared with the non-dislocation approach.
ABSTRACT
Objective:To compare reconstruction of acromioclavicular ligament versus internal fixation of acromioclavicular joint with clavicle hook plate in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular dislocation by reconstruction of coracoclavicular ligament with suture anchor.Methods:A retrospective analysis was conducted of the 56 patients who had been treated for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation from January 2015 to June 2019 at Department of Orthopaedic Trauma, Qilu Hospital of Shandong University (Qingdao). Of them, 26 were treated by reconstruction of coracoclavicular ligament with suture anchor plus reconstruction of acromioclavicular ligament (reconstruction group) and 30 by reconstruction of coracoclavicular ligament with suture anchor plus internal fixation of acromioclavicular joint with clavicle hook plate (plate group). The 2 groups were compared in terms of operation time, intraoperative blood loss, Constant-Murley score and Subjective Shoulder Rating System (SSRS) score at the last follow-up, and complications.Results:The 2 groups were comparable because there were no significant differences between them in the baseline data before operation ( P>0.05). The reconstruction group was followed up for 6 to 15 months (average, 7.9 months) while the plate group for 7 to 18 months (average, 11.3 months). The average operation time was (79.9±12.6) min for the reconstruction group and (69.1±8.5) min for the plate group, showing a significant difference ( P<0.05). No significant difference was found between the 2 groups in the intraoperative blood loss [(68.5±19.1) mL versus (65.0±16.6) mL] ( P>0.05). The differences were statistically significant between the 2 groups in Constant-Murley score (87.9±3.4 for the reconstruction group versus 91.9±3.5 for the plate group) and in SSRS score (85.1±4.1 for the reconstruction group versus 88.6±3.0 for the plate group) ( P<0.05). All the wounds healed well in the reconstruction group except for one patient who reported numbness around the wound which disappeared spontaneously 3 months postoperation. In the plate group, incision infection occurred in 2 cases, the redness and swelling in one which responded to dressing change 3 weeks later and numbness around the incision in one which was recovered 5 months after operation. Conclusions:Both surgical procedures can achieve good to excellent clinical outcomes. Although reconstruction of both acromioclavicular and coracoclavicular ligaments takes more operation time, it may lead to better Constant-Murley and SSRS scores and fewer complications, and spare secondary operation.
ABSTRACT
Objective:To evaluate of the clinical efficacy of Chinese herbal medicine Huaqi Powder and vitamin C among elderly patients with distal radius fractures in the chronic pain management. Methods:A total of 200 patients diagnosed with non-displaced distal radius fracture were enrolled by our hospital from March 2015 to February 2017, who were devided into Control Group (CG, 96 patients) and Treatment Group (TG, 104 patients) with randomized number table method. The Control Group took vitamin C orally and the Treatment Group took Huaqi Powder orally. Both groups were treated for 50 days. The VAS score, DASH (Disabilities of the Arm, Shoulder and Hand) score, occurrence of CRPS, mechanical pain threshold, serum levels of Neuron Growth Factor (NGF), C telopeptide of type I collagen (CTX-I) and Osteocalcin(OC) were measured and compared at the 26th and 52th weeks. Results:A total of 181 patients were followed up (85 in the CG and 96 in TG). At the 26th week, occurrence of CRPS in TG were significantly lower than that of the CG ( t=6.273, P<0.05), and both groups were followed up until fracture healing. The VAS and DASH scores in the TG were significantly lower than those in the control group ( t=5.768, 3.992, P<0.01); mechanical pain threshold of TG was significantly higher than that of the CG ( t=-2.759, P<0.01); plasma NGF level of the TG was significantly lower than that of the CG ( t=4.458, P<0.01). At the 52nd week of fracture, the mechanical pain threshold at the fracture of the TG was significantly higher than that of the control group ( t=-2.285, P<0.05) and plasma NGF levels were significantly lower than that of the CG ( t=6.175, P<0.01). Conclusions:The Huaqi Powder can decrease the short-term occurrence rate of CRPS among elderly patients after distal radius fracture. Huaqi Powder can also improve chronic pain, relieve the hyperpathia symptoms, and the potential mechanism may be related to the down-regulating of NGF expression.
