RESUMEN

BACKGROUND: Acromioclavicular joint (ACJ) disruptions are corrected by surgery either with an endobutton or a hook plate. The results in the long term were found to be similar in many randomized controlled trials. This study aims to conduct a meta-analysis to evaluate the functional outcome and complications of double endo button versus clavicular hook plate (CHP) for ACJ disruption (Rockwood types III-VI). MATERIALS AND METHODS: Two authors independently searched related articles from electronic databases (PubMed, Google Scholar, MEDLINE, SCOPUS, and Web of Science) till January 26, 2022. The data were extracted from the related articles and analyzed by Stata software. For bias calculation of each study, the Newcastle-Ottawa scale and the RevMan 5.4 software were used. RESULTS: 14 cohort studies, 2 randomized control trial studies, and 1 case-control study including patients were selected in this meta-analysis. The results of our study showed a significantly higher Constant-Murley Score (WMD 5.79, 95% confidence interval [CI] 2.23-9.36), Visual Analog Scale (WMD- 0.63, 95% CI [-0.79, -0.46]) and University of California at Los Angeles shoulder score (UCLA) scale (WMD 3.32, 95% CI [2.87, 3.77]) for double endobutton group. At the same time, some complications like implant failure were more common in the double endobutton group. CONCLUSION: This meta-analysis shows better functional and clinical outcomes of shoulder joint for the treatment of acromioclavicular joint (ACJ) disruption cases (Rockwood types III-VI) with no need for secondary operation, unlike the CHP. Complications like subacromial erosion, ACJ arthrodesis, and infection rate are higher in the CHP group, whereas the chance of implant failure is higher in the double endobutton group.

RESUMEN

Objective: To explore effectiveness of minimally invasive internal fixation with locking plates for mid-shaft clavicle fractures. Methods: Between October 2022 and August 2023, 28 patients with mid-shaft clavicle fractures were treated by minimally invasive internal fixation with locking plates. There were 10 males and 18 females with a mean age of 46.2 years (range, 18-74 years). The fractures were caused by traffic accident in 16 patients, sports-related injury in 7 patients, and other injuries in 5 patients. According to Robinson classification, the fractures were classified as type 2A1 in 1 case, type 2A2 in 6 cases, type 2B1 in 15 cases, and type 2B2 in 6 cases. The interval between fracture and operation ranged from 5 hours to 21 days (median, 1.0 days). The pain visual analogue scale (VAS) score was 8.1±1.6. The VAS score at 3 days after operation and the occurrence of complications after operation were recorded. During follow-up, X-ray films were re-examined to observe the healing of the fracture; the shoulder joint function was evaluated according to the Constant-Murley score at 6 months, and the length of the incision scar (total length of the distal and proximal incisions) was measured. Results: All operations were successfully completed without any subclavian vascular or nerve damage. All incisions healed by first intention. The VAS score was 1.2±0.7 at 3 days after operation, and there was a significant difference in VAS score between pre- and post-operation ( t=8.704， P<0.001). At 1 week after operation, the patient's shoulder was basically painless, and they resumed normal life. All patients were followed up 12-20 months (mean, 13.3 months). X-ray films showed that the bone callus began to form at 2-4 months after operation (mean, 2.7 months). There was no delayed healing or non healing of the fracture, and no loosening or fracture of the internal fixators during follow-up. At 6 months after operation, the mean total incision length was 1.5 cm (range, 1.1-1.8 cm); no patient complained of numbness or paresthesia on subclavicular region or anterior chest wall. The Constant-Murley score of shoulder joint function was 93-100 (mean, 97.6). Conclusion: Minimally invasive internal fixation with locking plates is a good surgical method for treating mid-shaft clavicle fractures, with simple operation, minimal trauma, good postoperative results, and high satisfaction.

RESUMEN

Thoracic outlet syndrome is a challenging clinical condition in terms of diagnosis, treatment, and health-related quality of life assessment. In this review, the authors provide a description of the clinical approach, surgical management, and longitudinal follow-up for patients with neurogenic, venous, and arterial thoracic outlet syndrome. The review represents the experiences of a high-volume, dedicated thoracic outlet syndrome program, where patients are treated in a multidisciplinary team and operative decompression occurs through primarily a supraclavicular approach. Data supporting the safety and efficacy of this approach are provided, as are clinical care considerations for surgeons treating patients with thoracic outlet syndrome.

RESUMEN

The initial treatment of open laryngeal trauma must be implemented immediately, with the primary focus on saving lives. However, in the later stages, various factors may cause changes in the structure and function of the larynx, which requires special attention. This article reports on the treatment process of a patient with depression who suffered from laryngeal trauma. Due to the late stage of laryngeal infection causing laryngeal defects, a hyoid epiglottis combined with sternocleidomastoid muscle clavicular flap repair was performed. Additionally, personalized functional exercise was performed, ultimately resulting in recovery.

RESUMEN

The purpose of this study is to evaluate trends in distal clavicle excision (DCE) in association with arthroscopic rotator cuff repair (RCR) from 2010 to 2019. The National Surgical Quality Improvement Program database was queried to identify all patients who underwent arthroscopic RCR from January 1, 2010 to December 31, 2019, and was further subdivided into procedure type: (1) isolated RCR; and (2) RCR with arthroscopic or open DCE. The proportion of each surgery type, by year and within groups, was calculated. The Cochran-Armitage test for trend was used to analyze yearly proportions of RCR with concomitant DCE. In a sample size of 19,163 patients, the proportion of RCR with DCE decreased from 51.2% to 40.8% (r = -0.830; p = 0.003). Although the results of this study suggest that surgeons are performing fewer DCEs in the setting of RCR, many DCEs are still being done.

RESUMEN

BACKGROUND: The current literature has differing views on the efficacy of concomitant distal claviculectomy (DC) during rotator cuff repair (RCR) in preventing revision surgery. Our aim was to investigate the revision surgery rate between RCR with DC and RCR without DC. METHODS: A retrospective cohort analysis was conducted using a national claims database. Patients undergoing open or arthroscopic primary RCR with or without concomitant DC were identified. The primary outcome was 4-year revision surgery rates. Univariate analysis was conducted using chi-square or Student t tests. Multivariable analysis was conducted using logistic regression, and an adjusted number needed to harm was calculated. RESULTS: A total of 131,232 patients met inclusion criteria. After logistic regression, patients undergoing RCR with DC had higher odds of requiring a subsequent DC procedure [OR; 95% CI; P-value (1.49; 1.35-1.64; P < 0.001)] but lower odds of any revision surgery (0.87; 0.80-0.91; P < 0.001) within 4 years than those who underwent RCR without DC. CONCLUSION: Although associated with a lower rate of overall revision surgeries within 2 and 4 years of RCR, those who underwent RCR with DC were 85% more likely at 2 years and 49% more likely at 4 years to undergo revision surgery of the distal clavicle than those without concomitant DC.

RESUMEN

BACKGROUND: A recent database study found that 15.2% of clavicle fractures underwent surgical treatment. Recent evidence accentuates the role of smoking in predicting nonunion. The purpose of this study was to further elucidate the effect of smoking on the 30-day postoperative outcomes after surgical treatment of clavicle fractures. METHODS: The authors queried the American College of Surgeons National Surgical Quality Improvement Program database for all patients who underwent open reduction and internal fixation of clavicle fracture between 2015 and 2020. Multivariate logistic regression, adjusted for notable patient demographics and comorbidities, was used to identify associations between current smoking status and postoperative complications. RESULTS: In total, 6,132 patients were included in this study of whom 1,510 (24.6%) were current smokers and 4,622 (75.4%) were nonsmokers. Multivariate analysis found current smoking status to be significantly associated with higher rates of deep incisional surgical-site infection (OR, 7.87; 95% CI, 1.51 to 41.09; P = 0.014), revision surgery (OR, 2.74; 95% CI, 1.67 to 4.49; P < 0.001), and readmission (OR, 3.29; 95% CI, 1.84 to 5.89; P < 0.001). CONCLUSION: Current smoking status is markedly associated with higher rates of deep incisional surgical-site infection, revision surgery, and readmission within 30 days after open reduction and internal fixation of clavicle fracture.

RESUMEN

BACKGROUND: It is aimed to compare the block onset times and performance features of costoclavicular techniques (medial and lateral approach) versus lateral sagittal technique. METHODS: Patients were randomized into three groups. For costoclavicular techniques, ultrasound probe was placed parallel to clavicle obtaining nerve cords, axillary artery and axillary vein visual from lateral-to-medial, respectively. The block needle was advanced from lateral (Group CLB) or medial (Group CMB) to perform costoclavicular block. For lateral sagittal technique (Group LSB), ultrasound probe was placed sagittal and perpendicular below the coracoid process to obtain sagittal artery image with the cords around. Total 20 ml of 0.5% bupivacaine and 10 ml of 2% lidocaine were deposited for all groups. Sensory and motor block onset times, block performance properties, complications, and patient/surgeon satisfactions were investigated. RESULTS: Among 56 patients, the primary outcome, sensory block onset time was shorter in Group CLB than Group CMB and Group LSB (10 [5-15], 10 [10-20], and 15 [10-15] minutes, respectively, p < 0.05). Motor block onset was also fastest in Group CLB (15 [10-20] mins for CLB, 20 [15-20] mins for LSB, and 22.5 [15-25] mins for CMB, p = 0.004). Block performance properties did not differ between the groups. The only complication observed was vascular puncture with an incidence of 28% in Group CMB. CONCLUSIONS: Lateral approach costoclavicular technique provides fastest block onset than the other techniques. Considering the success and safety profile, this technique stands as a good alternative in clinical practice. TRIAL REGISTRATION: This study is prospectively registered to clinicaltrials.gov on 20/02/2022 (NCT05260736).

RESUMEN

PURPOSE: We created an infrastructure for no code machine learning (NML) platform for non-programming physicians to create NML model. We tested the platform by creating an NML model for classifying radiographs for the presence and absence of clavicle fractures. METHODS: Our IRB-approved retrospective study included 4135 clavicle radiographs from 2039 patients (mean age 52 ± 20 years, F:M 1022:1017) from 13 hospitals. Each patient had two-view clavicle radiographs with axial and anterior-posterior projections. The positive radiographs had either displaced or non-displaced clavicle fractures. We configured the NML platform to automatically retrieve the eligible exams using the series' unique identification from the hospital virtual network archive via web access to DICOM Objects. The platform trained a model until the validation loss plateaus. Once the testing was complete, the platform provided the receiver operating characteristics curve and confusion matrix for estimating sensitivity, specificity, and accuracy. RESULTS: The NML platform successfully retrieved 3917 radiographs (3917/4135, 94.7 %) and parsed them for creating a ML classifier with 2151 radiographs in the training, 100 radiographs for validation, and 1666 radiographs in testing datasets (772 radiographs with clavicle fracture, 894 without clavicle fracture). The network identified clavicle fracture with 90 % sensitivity, 87 % specificity, and 88 % accuracy with AUC of 0.95 (confidence interval 0.94-0.96). CONCLUSION: A NML platform can help physicians create and test machine learning models from multicenter imaging datasets such as the one in our study for classifying radiographs based on the presence of clavicle fracture.

RESUMEN

This paper explores the role of botulinum neurotoxin in aiding fracture recovery through temporary muscle paralysis. Specifically, it investigates the effects of botulinum neurotoxin-induced paralysis of the sternocleidomastoid muscle on clavicle fractures in rats. The research aims to assess safety, effectiveness, and the impact on fracture healing. Healthy male Albino Wistar rats were divided into four groups: clavicle fracture, botulinum neurotoxin injection, both, and control. Surgeries were conducted under anaesthesia, and postoperatively, animals were monitored for 28 days. Euthanasia and radiological assessment followed, examining fracture healing and muscle changes, while tissues were histopathologically evaluated. The modified Lane-Sandhu scoring system was used for the radiographic evaluation of clavicle fractures, and the results varied from complete healing to nonunion. Histopathological examination at 28 days postfracture showed fibrous tissue, mesenchymal cells, and primary callus formation in all groups. Despite varied callus compositions, botulinum neurotoxin administration did not affect clavicle healing, as evidenced by similar scores to the control group. Several studies have explored botulinum neurotoxin applications in fracture recovery. Research suggests its potential to enhance functional recovery in certain types of fractures. Theoretical benefits include managing muscle spasticity, aiding reduction techniques, and preventing nonunion. However, botulinum neurotoxin's transient effect and nonuniversal applications should be considered. The present study found that botulinum toxin had no clear superiority in healing compared to controls, while histological evaluation showed potential adverse effects on muscle tissue. Further research is essential to understand its risk-benefit balance and long-term effects.
