Al-Dadah","doi":"10.1177/22104917221101409","DOIUrl":"https://doi.org/10.1177/22104917221101409","url":null,"abstract":"Background: Proximal humerus fractures and shoulder dislocations are relatively common. However, an associated rotator cuff tear is often missed with these injuries. The objective of this study was to assess the prevalence of a concomitant rotator cuff tear associated with common shoulder injuries. Methods: A cross-sectional epidemiological study of three patient populations: Group 1. Proximal Humerus Fractures; Group 2. Shoulder Dislocations; Group 3. Proximal Humerus Fracture-Dislocations. All patients within these three groups presented to and underwent subsequent management of their shoulder injury at a trauma unit. Management included both non-operative and operative intervention. Patients were evaluated for associated rotator cuff tears. Results: This study included a total of 196 patients: Group 1 = 146 Proximal Humerus Fractures; Group 2 = 37 Shoulder Dislocations; Group 3 = 13 Proximal Humerus Fracture-Dislocations. Of the 196 patients in total, 23 (11.7%) sustained a concomitant rotator cuff tear. The highest number of tears was found in Group 1 (n = 14). However, the highest percentage prevalence of tears was in Group 2 (18.9%). There was noted to be a higher prevalence of rotator cuff tears with increasing age. Twenty-two (95.7%) rotator cuff tears were detected in patients over 50 years of age. The vast majority of rotator cuff tears were detected by ultrasound (78.3%) as opposed to magnetic resonance imaging (21.7%). The majority of tears were full-thickness (60.9%). Of the 23 patients with a concomitant rotator cuff tear, 17 involved a single tendon (73.9%) and supraspinatus was most common (69.6%). Conclusions: A concomitant rotator cuff tear in association with a proximal humerus fracture, shoulder dislocation or proximal humerus fracture-dislocation is relatively common. The overall rotator cuff tear prevalence in this study was 11.9%. Rotator cuff tears are more likely to occur in patients over 50 years old and those sustaining a shoulder dislocation.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"10 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85947214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment of choice of surgery is still controversial. This is a retrospective analysis of clinical and radiological outcomes of long and short segment stabilization for patients admitted with thoracolumbar fracture in our hospitals. Material and Method: Inclusion criteria included a single level of thoracolumbar fracture, excluding pre-existing deformity or spinal surgery, osteoporosis, and pathological fracture. Clinical parameters included visual analogue scale (VAS), operative time, intraoperative blood loss, and postoperative length of stay. Radiological parameters included wedge angle and anterior and posterior vertebral height ratio. Results: From June 2007 to May 2020, 56 patients (male = 31, female = 25) were recruited. There were 25 patients in the short segment group (open = 11, minimal invasive surgery (MIS) = 14) and 31 patients in the long segment group. Clinically, significantly better VAS at 6 months (1 vs. 1.96; p = 0.041), shorter post-op length of stay (16 days vs. 25 days; p = 0.01), and less blood loss (178 ml vs. 824 ml; p < 0.01) were found in the short segment group. Radiologically, the short segment group showed significantly better wedge angle at immediate (5° vs. 9.23°; p = 0.002) and long-term follow-up (7.41° vs. 11.43°; p = 0.01). Moreover, the short segment group has significantly better post-op anterior and posterior vertebral height ratios. Within the short segment group, the MIS group showed significantly less blood loss (82 ml vs. 303 ml; p < 0.01). However radiological parameters favour the open group. Discussion and Conclusion: For single-level thoracolumbar fracture, both long and short stabilizations were effective in reducing and stabilizing the fracture. However, the short segment group showed significantly superior results. Moreover, a minimally invasive technique in short segment stabilization showed even less blood loss but less optimal radiological results. Therefore, short segment stabilization could be the treatment of choice for traumatic thoracolumbar spine fractures.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"23 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87368179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a lack of knowledge in young patients of developing countries, there is a delay in presentation from the first time of dislocation. The aim of this retrospective study was to evaluate the functional and radiographic outcomes of patients with shoulder instability after the Congruent Arc Latarjet procedure. Methods: From January 2018 to November 2021, 20 patients with history of recurrent shoulder dislocation having glenohumeral instability were treated surgically in our institute. Open Congruent Arc Latarjet procedure was performed in 20 patients. Functional outcomes were assessed preoperatively and postoperatively based on American Shoulder and Elbow Surgeons (ASES) score, the visual analog scale (VAS) for pain, ROWE score, and Active range of motion in the diseased shoulder. Results: Twenty shoulders of 20 patients were evaluated for a mean period of 24 months postoperatively. At the time of the latest consultation, the range of motion and the shoulder functional evaluations based on ROWE score which was 89.64 ± 5.71 (range 80–95) improved from 20.36 ± 8.87 (range 10–30), p = 0.001. The mean preoperative ASES score was 22.60 ± 1.09 (range 20.6–25) which improved to 72.50 ± 7.33 (range 52.8–77.2), p = 0.001, which is definitely improved. The overall re-dislocation rate was 0% (0 of 20). In our study, 60% had excellent outcomes, 30% had good outcomes, and 10% had fair outcomes. Conclusion: The Congruent Arc Latarjet procedure for the treatment of recurrent shoulder dislocation with glenoid bone loss of >20% is a successful and efficient method with better outcomes in daily work profile and no further episode of redislocation.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"14 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85550292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many strategies for treatment have been reported but according to the current literature, controversy remains. Objectives: To compare the clinical and radiological outcomes of medializing calcaneal osteotomy utilizing modified step plate and subtalar arthroereisis utilizing conical subtalar implant for patients with symptomatic flexible pes planus. Methods: A prospective, randomized, double center study was conducted between May 2017 and May 2019 at the Foot and Ankle Department of Cairo University Hospital and El Sahel Teaching Hospital on 26 patients (37 feet) with flexible flat feet to compare between medial displacement calcaneal osteotomy using modified locked step plate (group A) compromising 17 feet and arthroereisis using subtalar implant (group B) compromising 20 feet. Results: By the end period of the study, 25 males and 12 females were available for our analysis of results with a mean follow-up period of 10.14 months (range 7–14 months), clinical scoring (American Orthopaedic Foot and Ankle Society score, Foot Functional Index) with radiological analysis revealed a non-significant difference between both groups, the overall complication rate was 16.2%. Conclusion: Both medial displacement calcaneal osteotomy and subtalar arthroereisis significantly improved radiographic and subjective clinical outcome measures in the surgical treatment of painful flexible planovalgus feet. The less-invasive nature and lower potential morbidity suggest that judicious use of arthroereisis implants is an appropriate alternative.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89579680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the risk factors and the incidence of foot and ankle (F/A) problems in (UKA) arthroplasty patients. Methods Patients who underwent UKA between 2016 and 2019 in our clinic were evaluated and the presence of F/A problems was recorded. Radiologic evaluations included hip knee ankle angle (HKA), medial proximal tibial angle, posterior tibial slope angle, talar tilt angle, talar inclination, talar dome to mechanical axis (TDMA), and talocrural angle (TCA) measured on preoperative and follow-up long-leg standing radiographs. The range of motion, Q angles, and muscle strengths were measured. Visual analog scale, physical performance limitations, and patient-reported activity limitations were evaluated for all patients. Patients with reported F/A problems were additionally evaluated with Foot Functional Index. Results Forty-four patients (38 female, 6 male; mean age 58.66 ± 8.6 years; mean BMI 31.30 ± 3.81, mean follow-up period 34.22 ± 18.95 months) were included in the study. There were 13 patients (29.5%) with reported F/A problems. Postoperative comparison of patients with and without F/A problems showed statistically significant differences in only WOMAC and SF12 physical health sub-scores (p = 0.002, p = 0.003, respectively). There was no significant postoperative change in TDMA in patients with F/A problems (p > 0.05) in contrast to patients without F/A problems (p = 0.006). There was no statistically significant difference in preoperative TCA measurements between groups (p = 0.79). Comparison of knee and ankle radiologic measurements between groups demonstrated significant difference only in postoperative HKA measurements (−2.82 ± 2.53 vs. −0.80 ± 3.12, p = 0.033).

Functional restitution depends on many factors including the type of prosthesis available. We report our experience of providing advanced artificial limbs at free of cost to the underprivileged through a state-sponsored pilot initiative. Material and methods: This is a retrospective cohort study of amputees who have been rehabilitated with advanced artificial limbs through the Department of Orthopaedics at Nizam's Institute of Medical Sciences, Punjagutta, Hyderabad, India from the years 2017 to 2021. Prostheses were procured through rate contract and monitory support was provided by the state. Evaluation, fitment and functional restitution were supervised by the orthopaedic surgeons to the utmost satisfaction of the amputees. Results: A total of 136 subjects received 142 advanced artificial limbs. Out of 136 subjects, 130 received unilateral and 6 subjects received bilateral prosthesis. Ninety-two percent (n  =  125) were men and 8% (n  =  11) were women. Eighty-eight (n  =  125) were lower limb prosthesis and 12% (n  =  17) were upper limb prosthesis. All the amputees fitted with advanced artificial limbs were highly satisfied at the end of the procedure and were confident of independent living. Conclusion: Appropriate rehabilitative measures are required for amputees to lead an independent life. Paucity of institutional support and monitory challenges preclude them from advanced prosthesis. State-sponsored, institute-based supply of advanced artificial limbs at free of cost to the beneficiaries is a replicable and feasible option for optimal rehabilitation of amputees with appropriate prosthesis.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"13 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84976888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The randomized, prospective and comparative study was conducted in 60 patients who were treated with bone grafting as a part of their treatment plan. Group A underwent the outer cortex technique (20 patients), Group B underwent the inner cortex technique (20 patients) and Group C underwent the table splitting technique (20 patients). The comparison of morbidities associated with various techniques of anterior iliac crest bone graft harvesting was done for a period of one year. Results: Most common morbidity observed was pain, measured by the visual analogue scale score (60/60, 100% of patients). The visual analogue scale score was significantly higher for the outer cortex group followed by the inner cortex group, and then the lowest score was for the table splitting group (p < 0.05). Followed by numbness (40/60, 66%), least in the table splitting group and maximum in the outer cortex group (p < 0.05). Next was abnormal gait, which was mostly seen in patients with the outer table method and least in the table split group (p < 0.05). Other complications were infections (4), itching at the surgical site (3) and hematoma (1). There were no significant difference regarding scar satisfaction among comparison groups. Conclusion: we conclude that few differences do exist in harvest-site morbidities between different techniques used in our study. Overall, the most common morbidity observed were pain, numbness and abnormal gait. However, the table splitting group has the lowest morbidity, therefore bone harvesting by the table splitting appears to be a very good option.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"12 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85984289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
