Ultrasound of the Rotator Cuff in Non-Fractured Shoulder Trauma: 30 Cases at the Yalgado Ouedraogo University Hospital of Ouagadougou (Burkina Faso)

Introduction: Ultrasound is the imaging technique of choice for the study of rotator cuff lesions. However, in the case of shoulder trauma, it is rarely requested in our context. This study aimed to show ultrasound lesions of the rotator cuff in cases of non-fracture shoulder trauma at the CHUYO in Ouagadougou. Methodology: This was a prospective descriptive cross-sectional study running from August 1 to November 30, 2017, in the medical imaging department of CHUYO. The study population consisted of patients received in the department for ultrasound in the context of non-fracture shoulder trauma. Results: We collected 20 cases (66.67%) of rotator cuff lesions out of 30 non-fracture shoulder injuries. The mean age of the patients was 27.6 years. Road traffic accidents accounted for 60% of injuries, sports accidents for 30%, and domestic accidents for 10%. Ultrasound lesions were mainly tendon ruptures (36.67%) and tendinitis (23.33%). Ruptures were non-transfixing in 90.90% of cases. The supraspinatus was the most affected (81.81%). Conclusion: Ultrasound can help diagnose rotator cuff injuries, particularly in non-fractured shoulder trauma.

Functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair

AIM To compare the functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair. METHODS Eighty-seven patients with rotator cuff tears following arthroscopic treatment were divided into traumatic and non-traumatic tear groups. Postoperative muscle strength and outcomes using the modified University of California, Los Angeles score were evaluated. Sex, age, affected limb and dominant limb were correlated between groups. Muscle strength of the repaired and unaffected shoulders was compared. Rotator cuff injury size was measured. RESULTS Of the 87 patients who underwent rotator cuff repairs, 35 had traumatic tears and 52 had non-traumatic tears. In patients with non-traumatic tears, the average age was 59 years, 74.5% were female, 96.1% were righthand dominant and 92.3% had their dominant shoulder affected. Patients with traumatic tears were 59.5 yearsold on average, 51.4% were female, 91.4% were righthand dominant and 88.5% had their dominant shoulder affected. No difference existed in the mean modified University of California, Los Angeles score between patients with traumatic tears(33.7) compared with those with non-traumatic tears(32.8). No strength differences were observed between groups: The strength difference between the non-affected and affected sides was 1.21 kg in the non-traumatic group and 1.39 kg in the traumatic group(P = 0.576), while the strength ratio between the non-affected/affected sides was 0.805 in the nontraumatic group and 0.729 in the traumatic group(P = 0.224). CONCLUSION The functional results of traumatic rotator cuff repairs are similar to non-traumatic tears. Both outcomes are satisfactory.

Arthroscopic treatment options for irreparable rotator cuff tears of the shoulder

The management of patients with irreparable rotator cuff tears remains a challenge for orthopaedic surgeons with the final treatment option in many algorithms being either a reverse shoulder arthroplasty or a tendon transfer. The long term results of these procedures are however still widely debated, especially in younger patients. A variety of arthroscopic treatment options have been proposed for patients with an irreparable rotator cuff tear without the presence of arthritis of the glenohumeral joint. These include a simple debridement with or without a biceps tenotomy, partial rotator cuff repair with or without an interval slide, tuberplasty, graft interposition of the rotator cuff, suprascapular nerve ablation, superior capsule reconstruction and insertion of a biodegradable spacer(Inspace) to depress the humeral head. These options should be considered as part of the treatment algorithm in patients with an irreparable rotator cuff and could be used as either as an interim procedure, delaying the need for more invasive surgery in the physiologically young and active, or as potential definitive procedures in the medically unfit.The aim of this review is to highlight and summarise arthroscopic procedures and the results thereof currently utilised in the management of these challenging patients.

Reporting rotator cuff tears on magnetic resonance arthrography using the Snyder's arthroscopic classification

AIM To determine diagnostic performance of magnetic resonance arthrography(MRA) in evaluating rotator cuff tears(RCTs) using Snyder's classification for reporting.METHODS One hundred and twenty-six patients(64 males, 62 females; median age 55 years) underwent shoulder MRA and arthroscopy, which represented our reference standard. Surgical arthroscopic reports were reviewed and the reported Snyder's classification was recorded. MRA examinations were evaluated by two independent radiologists(14 and 5 years' experience) using Snyder's classification system, blinded to arthroscopy. Agreement between arthroscopy and MRA on partial-and fullthickness tears was calculated, first regardless of their extent. Then, analysis took into account also the extent of the tear. Interobserver agreement was also calculated the quadratically-weighted Cohen kappa statistics.RESULTS On arthroscopy, 71/126 patients(56%) had a fullthickness RCT. The remaining 55/126 patients(44%) had a partial-thickness RCT. Regardless of tear extent, out of 71 patients with arthroscopically-confirmed fullthickness RCTs, 66(93%) were correctly scored by both readers. All 55 patients with arthroscopic diagnosis of partial-thickness RCT were correctly assigned as having a partial-thickness RCT at MRA by both readers. Interobserver reproducibility analysis showed total agreement between the two readers in distinguishing partial-thickness from full-thickness RCTs, regardless of tear extent(k = 1.000). With regard to tear extent, in patients in whom a complete tear was correctly diagnosed, correct tear extent was detected in 61/66 cases(92%); in the remaining 5/66 cases(8%), tear extent was underestimated. Agreement was k = 0.955. Interobserver agreement was total(k = 1.000).CONCLUSION MRA shows high diagnostic accuracy and reproducibility in evaluating RCTs using the Snyder's classification for reporting. Snyder's classification may be adopted for routine reporting of MRA.

A Retrospective Analysis of the Effectiveness of MRI and Ultrasound in Identifying Rotator Cuff Tears

Magnetic Resonance Imaging (MRI) and Ultrasound (US) imaging are both routinely used in the assessment of rotator cuff pathology. Factors influencing the frequency of use of the respective technologies include access to equipment, provider preference, and cost. The purpose of our study was to compare the accuracy of in clinic ultrasound with that of MRI in diagnosing pathology of the rotator cuff in a large sample size with limited exclusionary criteria. 500 patient profiles assessed by each imaging type, MRI and ultrasound, who then proceeded to arthroscopic surgery were gathered and analyzed for interobserver agreement between the image interpretation and the surgical observations. While ultrasound displayed slightly higher sensitivity and specificity ratings in the diagnosis of full tears (0.90 and 0.92 vs. 0.86 and 0.91), MRI had a higher sensitivity (0.87 vs. 0.80) and Ultrasound had a higher specificity (0.86 vs. 0.76) for general cuff damage. The Weighted Kappa Values for both MRI (0.699) and Ultrasound (0.668) both indicate a substantial strength of agreement between the image interpretation and surgical findings. While there was a balanced distribution of errors observed in the MRI category, the most common error made in the Ultrasound assessment was a false negative assessment of a partial tear. The data indicate that in a clinical setting Ultrasound imaging is a cost-effective and accurate alternative to MRI and can be a valuable addition to the diagnostic assessment of rotator cuff injury and pathology.

Assessing the accuracy of arthroscopic and open measurements of the size of rotator cuff tears: A simulation-based study

BACKGROUND Arthroscopic procedures are commonly performed for rotator cuff pathology.Repair of rotator cuff tears is a commonly performed procedure.The intraoperative evaluation of the tear size and pattern contributes to the choice and completion of the technique and the prognosis of the repair.AIM To compare the arthroscopic and open measurements with the real dimensions of three different patterns of simulated rotator cuff tears of known size using a plastic shoulder model.METHODS We created three sizes and patterns of simulated supraspinatus tears on a plastic shoulder model(small and large U-shaped,oval-shaped).Six orthopaedic surgeons with three levels of experience measured the dimensions of the tears arthroscopically,using a 5 mm probe,repeating the procedure three times,and then using a ruler(open technique).Arthroscopic,open and computerized measurements were compared.RESULTS A constant underestimation of specific dimensions of the tears was found when measured with an arthroscope,compared to both the open and computerized measurements(mean differences up to-7.5±5.8 mm,P<0.001).No differences were observed between the open and computerized measurements(mean difference-0.4±1.6 mm).The accuracy of arthroscopic and open measurements was 90.5%and 98.5%,respectively.When comparing between levels of experience,senior residents reported smaller tear dimensions when compared both to staff surgeons and fellows.CONCLUSION This study suggests that arthroscopic measurements of full-thickness rotator cuff tears constantly underestimate the dimensions of the tears.Development of more precise arthroscopic techniques or tools for the evaluation of the size and type of rotator cuff tears are necessary.

Elasticity of the Coracoacromial Ligament in Shoulders with Rotator Cuff Tears: Measurement with Ultrasound Elastography

Background: The symptoms of rotator cuff tear vary and may even be absent. Thus, the symptoms cannot be explained solely by the presence of rotator cuff tear, and other factors are thought to be involved. Because the rotator cuff comes in contact with the coracoacromial ligament, the elasticity of the ligament may be a factor of the symptoms. The purpose of this study was to clarify the elasticity of the coracoacromial ligament in live shoulders with rotator cuff tears. Methods: Forty-one shoulders in 24 persons were enrolled in this study. The average age was 52 years old (range, 15 - 84 years old). We investigated the presence of rotator cuff tear and measured the elasticity of the coracoacromial ligament by ultrasound elastography (EUB-7500, HITACHI, Japan). Ultrasound elastography was a useful method to quantify the strain of soft tissue when pressure was added. The strain ratio (the ratio of strain of the coracoacromial ligament to that of the rotator cuff) was used as the index of the elasticity of coracoacromial ligament. Thus, the higher the strain ratio was, the softer the ligament was. Results: The strain ratio of the coracoacromial ligaments without rotator cuff tear showed a negative correlation to the age (r = ﹣0.825, P 0.01). The strain ratio of the ligaments with rotator cuff tear (23.75 ± 15.05, 69.6 years old) was higher than that of the older ligaments without cuff tear (12.62 ± 7.94, 64.6 years old) (P = 0.0486). In shoulders with rotator cuff tear, the strain ratio of the ligaments with pain (14.37 ± 10.15, 66.7 years old) was lower than that of ligaments without pain (33.12 ± 13.59, 69.1 years old) (P = 0.0221). Conclusions: The coracoacromial ligament became stiffened with aging but softened with the existence of rotator cuff tear. The ligaments with symptomatic cuff tear are more stiffened than the ligaments with asymptomatic cuff tear.

Knot impingement after arthroscopic rotator cuff repair mimicking infection:A case report

BACKGROUND Knot impingement as a complication after arthroscopic rotator cuff repair(ARCR)has been suggested as a cause of persistent pain with limited motion.We report on a case involving a patient who developed knot impingement after ARCR who complained of acute onset of pain with limited motion,which was confused with infection.CASE SUMMARY A 55-year-old female who complained of severe pain with limited motion of the right shoulder visited our emergency room.Passive range of motion could not be evaluated due to the patient’s severe pain.The patient had undergone ARCR using a suture-bridge technique at a local clinic four months ago for treatment of a small supraspinatus tear of the right shoulder.An erosive change of the undersurface of the acromion was observed on plain radiographs of the right shoulder,and a moderate amount of bursal fluid and synovial thickening with enhancement was observed by magnetic resonance imaging.Results of an analysis of the aspirated fluid showed that the WBC count was 3960 with 90% neutrophils.The arthroscopic view showed healing of the repaired supraspinatus tendon and loose suture threads and knots with severe subacromial bursitis were observed.Debridement of inflammatory tissues of the glenohumeral joint and subacromial space was performed for the removal of all suture materials.The patient’s symptoms subsided immediately after the surgical procedure.CONCLUSION Although the incidence of knot impingement is rare,the possibility of knot impingement after ARCR should be a consideration.

Clinical Decision Making in Open vs Arthroscopic Rotator Cuff Repair: Evidence for Preoperative Decision Making

Objective: To further understand what factors should be considered when deciding to do mini-open versus arthroscopic rotator cuff repair. Methods: A systematic literature search on the computer was done with the help of the PubMed database. Of the articles searched through, three have been chosen to specifically address topics of interest concerning the factors affecting arthroscopic vs mini-open RCR surgical approaches. Discussion: As we continue to progress down the line of factors impacting a clinician’s decision making, we begin to see how postoperative management is unchanged. Tear severity lacks sufficient evidence to base a decision on, but financial, educational, and logistical factors are proven to play a significant role in this decision. Conclusion: As of right now it seems that mini-open RCR is the most cost and time efficient method, especially amongst non-fellowship trained surgeons or ones with lower volume of shoulder scopes. However, further studies should be done to examine cost and efficiency in Sport Medicine fellowship trained orthopedic surgeons to validate these findings.

Therapeutic Effect of Single-row Technique and Nocompression Sputum in the Treatment of Post Small and Medium Rotator Cuff Injury under Shoulder Arthroscopy

Objective.To investigate the clinical effect of single-row fixation and non-conjunction compression in the treatment of post small and medium rotator cuff injuries under arthroscopy.Methods.Forty-five patients admitted to our department from June 2018 to May 2019 were enrolled in the study.32 patients in the single-row fixed-group and 13 patients in the non-conjunctival group were randomly assigned.The VAS,ASES,and UCLA scores of the two groups were compared before surgery,one month,three months,and six months after surgery[1].Results.The VAS,ASES,and UCLA scores were significantly higher in those two groups other than the preoperative group.The scores of the two groups were gradually improved from one month,three months,and six months respectively after surgery.At one month,the scores of those two groups were statistically significant(P<0.05),but there was no significant difference between the two groups at three months and six months(P>0.05).Conclusion.Under arthroscopy,the single-row fixation technique and the non-conjunction compression method were used to treat post small and medium rotator cuff injuries.The effect is very significant.In particular,the no-knot sputum method has a significant improvement in restoring postoperative pain,joint activity and joint strength.

Sonographic evaluation of the post-operative rotator cuff: Does tendon thickness matter?

The goal of this work is to determine whether sonographic measures of tendon thickness correlate with post-operative functional parameters or re-tear rates. 53 consecutive patients with supraspinatus tears on MRI were examined by an orthopedic surgeon to determine: pre-and post-operative patient pain (via Constant-Murley scale), night time pain, maximum force production by the affected arm (in pounds), and range of motion deficits. Post-operative ultrasound at 3 and 12 months following surgery was performed to evaluate for recurrent tear and to measure tendon thickness. Post-operative tendon thickness was inversely related to patient age (r = -0.24;p value of tendon thickness. Post-operative tendon thickness did not successfully predict post-operative functional outcomes or pain levels (p > 0.05). Normal post-operative tendon thickness of the rotator cuff decreases from 3 to 12 months following surgery. Thickness is reduced in patients with more severe tears and in older patients but does not correlate with post-operative patient pain or functional outcomes.

Application of multidisciplinary team-based integrated traditional Chinese medicine and Western medicine in rotator cuff injury patients undergoing arthroscopic surgery

BACKGROUND Arthroscopic rotator cuff repair is a common surgical treatment for rotator cuff injuries(RCIs).Although this procedure has certain clinical advantages,it requires rehabilitation management interventions to ensure therapeutic efficacy.AIM To investigate the effect of integrated traditional Chinese medicine and Western medicine(TCM-WM)under the multidisciplinary team(MDT)model on the postoperative recovery of patients undergoing arthroscopic surgery for RCIs.METHODS This study enrolled 100 patients who underwent arthroscopic rotator cuff repair for RCIs at the Seventh People’s Hospital of Shanghai University of Traditional Chinese Medicine between June 2021 and May 2024.They were divided into a control group(n=48)that received routine rehabilitation treatment and an experimental group(n=52)that received TCM-WM under the MDT model(e.g.,acupuncture,TCM traumatology and orthopedics,and rehabilitation).The results of the Constant–Murley Shoulder Score(CMS),Visual Analogue Scale(VAS),Shoulder Pain and Disability Index(SPADI),muscular strength evaluation,and shoulder range of motion(ROM)assessments were analyzed.RESULTS After treatment,the experimental group showed significantly higher CMS scores in terms of pain,functional activity,shoulder joint mobility,and muscular strength than the baseline and those of the control group.The experimental group also exhibited significantly lower VAS and SPADI scores than the baseline and those of the control group.In addition,the experimental group showed significantly enhanced muscular strength(forward flexor and external and internal rotator muscles)and shoulder ROM(forward flexion,abduction,and lateral abduction)after treatment compared with the control group.CONCLUSION TCM-WM under the MDT model improved shoulder joint function,relieved postoperative pain,promoted postoperative functional recovery,and facilitated the recovery of muscular strength and shoulder ROM in patients with RCIs who underwent arthroscopic rotator cuff repair.
