Partial rotator cuff tears are the most common pathology of the shoulder joint. Diagnostic of such conditions is a challenging problem for trauma surgeon.Purpose of the study is to analyze the diagnostic significance of manual tests and the standard MRI of the shoulder joint.Materials and Methods. The study is a retrospective analysis of disease history data of 25 patients (15 males, 10 females) treated at the authors’ hospital during the period from 2014 to 2017. Examination was performed according to a standard protocol: assessment of shoulder range of motion, palpation, manual examination, including “full/empty can” test, a painful arc symptom and the Hawkins – Kennedy test. All patients underwent MRI of the shoulder joint. The mean age of patients was 50.8 years. Shoulder joint arthroscopic inspection was considered the gold standard for diagnostics.Results. After data analysis, the following results were obtained: sensitivity of the “full can” test was 68%, the accuracy was 68%; “empty can” test sensitivity and accuracy were 76%, respectively. MRI sensitivity for diagnostics of supraspinatus tendon ruptures was 84% with the accuracy of 84%. The combination of the Hawkins – Kennedy test with the symptom of painful arch demonstrated accuracy and sensitivity of 64%. The study evaluated the effectiveness of MRI for diagnostic of the rupture type: sensitivity for injury from the joint surface — 80%, from the subacromial space — 70%; specificity for ruptures from the articular surface — 90% and from the subacromial space — 93%. The accuracy was 84% for both types of ruptures.Conclusions. Combined application of manual tests and MRI of the shoulder joint allows to diagnose partial rotator cuff tears in the majority of cases.

A Prospective Study

Background. Large, massive irreparable rotator cuff tears lead to a significant decrease in the function of the shoulder joint together with the development of a pronounced pain syndrome. Such injuries are difficult to treat, and the number of relapses, when trying to restore them, is quite high. The installation of a subacromial balloon is the method of choice for this group of patients and allows restoring the function of the shoulder joint fairly successfully. Aim: to evaluate the results of the treatment of patients with massive irreparable rotator cuff tears injuries in a prospective study from 2016 to 2018. Methods. The results of the arthroscopic treatment of large, irreparable rotator cuff injuries in 25 patients (with the average age of 67 5 years) with the installation of a subacromial balloon are presented. In all the clinical cases, there was a pronounced (grades 34, according to the Goutallier classification) fatty dystrophy of the rotator cuff muscles (supraspinatus or in combination with subaspinatus). All the patients underwent the subacromial space release with a thorough bursectomy and subsequent installation of a subacromial balloon. Results. The average score on the UCLA scale was 14 3 points (1117) before the operation and 312 points (2933) 12 months after the operation, the results were considered good and excellent. Conclusion. The results obtained allow us to evaluate the described technique as low-traumatic, simple and fast in its accomplishment, aimed at the reduction of the pain syndrome and restoration of the upper extremity function.

Superior Capsular Reconstruction

Abstract Background Irreparable rotator cuff tears are common and difficult to treat. Techniques for “filling the loss of substance” require fixation to the rotator cuff stump (tendon augmentation) or to the glenoid (superior capsular reconstruction), which are complicated by the narrow working zone of the subacromial space. The main objective of this study was to determine whether a braided graft of gracilis (GR) and semitendinosus (ST) could fill a loss of tendon substance from an irreparable rupture of the supra- and infraspinatus, by fixing the graft to the greater tuberosity and the spine of the scapula. Methods This was a cadaveric study with the use of ten specimens. The GRA and ST tendons were harvested, braided and reinforced with suture. An experimental tear of the supraspinatus (SS) and upper infraspinatus (IS) retracted at the glenoid was made. The GRAST transplant was positioned over the tear. The transplant was attached to the greater tuberosity by two anchors and then attached to the medial third of the scapular spine by trans-osseous stitching. The percentage of filling obtained was then measured and passive mobility of the shoulder was assessed. We proceeded to the same technique under arthroscopy for a 73 years old patient whom we treated for a painful shoulder with irreparable cuff tear. We inserted a GRAST graft using arthroscopy. Results The Braided-GRAST allowed a 100% filling of the loss of tendon substance. Mobility was complete in all cases. Conclusion This technique simplifies the medial fixation and restores the musculo-tendinous chain where current grafting techniques only fill a tendinous defect. The transplant could have a subacromial “spacer” effect and lower the humeral head. The donor site morbidity and the fate of the transplant in-vivo are two limits to be discussed. This anatomical study paves the way for clinical experimentation.

Biceps Tenotomy

Background: Lesions of the long head of the biceps tendon are often associated with massive rotator cuff tears (MRCTs), and biceps tenotomy is frequently performed for pain relief and functional reservation. However, the efficacy and safety of biceps tenotomy regarding the effects on the surrounding tissues in chronic MRCT are unclear. Hypothesis: Biceps tenotomy would result in improved mechanical and histological properties of the intact subscapularis tendon and improved in vivo shoulder function while not compromising glenoid cartilage properties. Study Design: Controlled laboratory study. Methods: Right supraspinatus and infraspinatus tendons were detached in 25 male Sprague-Dawley rats, followed by 4 weeks of cage activity to create a chronic MRCT condition. Animals were randomly divided into 2 groups and received either biceps tenotomy (n = 11) or sham surgery (n = 14) and were sacrificed 4 weeks thereafter. Forelimb gait and ground-reaction forces were recorded 1 day before the tendon detachment (baseline), 1 day before the surgical intervention (biceps tenotomy or sham), and 3, 7, 10, 14, 21, and 28 days after the intervention to assess in vivo shoulder joint function. The subscapularis tendon and glenoid cartilage were randomly allocated for mechanical testing or histologic assessment after the sacrifice. Results: Compared with sham surgery, biceps tenotomy partially restored the in vivo shoulder joint function, with several gait and ground-reaction force parameters returning closer to preinjury baseline values at 4 weeks. With biceps tenotomy, mechanical properties of the subscapularis tendons were improved, while mechanical properties and histological Mankin scores of the glenoid cartilage were not diminished when compared with the sham group. Conclusion: Biceps tenotomy in the presence of chronic MRCT partially preserves overall shoulder function and potentially restores subscapularis tendon health without causing detrimental effects to joint cartilage. This laboratory study adds to the growing literature regarding the protective effects of biceps tenotomy on the shoulder joint in a chronic MRCT model. Clinical Relevance: This study provides important basic science evidence supporting the use of biceps tenotomy in patients with massive rotator cuff tears.

Cuff Repair

Rotator cuff tears result in shoulder pain, stiffness, weakness and loss of motion. After surgical repair, high failure rates have been reported based on objective imaging and it is recognized that current surgical treatments need improvement. The aim of the study was to assess whether implants composed of freeze-dried chitosan (CS) solubilized in autologous platelet-rich plasma (PRP) can improve rotator cuff repair in a rabbit model. Complete tears were created bilaterally in the supraspinatus tendon of New Zealand White rabbits ( n = 4 in a pilot feasibility study followed by n = 13 in a larger efficacy study), which were repaired using transosseous suturing. On the treated side, CS-PRP implants were injected into the transosseous tunnels and the tendon itself, and healing was assessed histologically at time points ranging from one day to two months post-surgery. CS-PRP implants were resident within transosseous tunnels and adhered to tendon surfaces at one day post-surgery and induced recruitment of polymorphonuclear cells from 1 to 14 days. CS-PRP implants improved attachment of the supraspinatus tendon to the humeral head through increased bone remodelling at the greater tuberosity and also inhibited heterotopic ossification of the supraspinatus tendon at two months. In addition, the implants did not induce any detectable deleterious effects. This preliminary study provides the first evidence that CS-PRP implants could be effective in improving rotator cuff tendon attachment in a small animal model.

The Relationship

Background: Rotator cuff tears may result from repeated mechanical deformation of the cuff tendons, and internal impingement of the supraspinatus tendon against the glenoid is one such proposed mechanism of deformation. Purpose: To (1) describe the changing proximity of the supraspinatus tendon to the glenoid during a simulated overhead reaching task and (2) determine the relationship between scapular morphology and this proximity. Additionally, the patterns of supraspinatus-to-glenoid proximity were compared with previously described patterns of supraspinatus-to-coracoacromial arch proximity. Study Design: Descriptive laboratory study. Methods: Shoulder models were created from magnetic resonance images of 20 participants. Standardized kinematics were imposed on the models to simulate functional reaching, and the minimum distances between the supraspinatus tendon and the glenoid and the supraspinatus footprint and the glenoid were calculated every 5° between 0° and 150° of humerothoracic elevation. The angle at which contact between the supraspinatus and the glenoid occurred was documented. Additionally, the relationship between glenoid morphology (version and inclination) and the contact angle was evaluated. Descriptive statistics were calculated for the minimum distances, and glenoid morphology was assessed using Pearson correlation coefficients and simple linear regressions. Results: The minimum distances between the tendon and the glenoid and between the footprint and the glenoid decreased as elevation increased. Contact between the tendon and the glenoid occurred in all participant models at a mean elevation of 123° ± 10°. Contact between the footprint and the glenoid occurred in 13 of 20 models at a mean of 139° ± 10°. Less glenoid retroversion was associated with lower tendon-to-glenoid contact angles ( r = –0.76; R 2 = 0.58; P < .01). Conclusion: This study found that the supraspinatus tendon progressively approximated the glenoid during simulated overhead reaching. Additionally, all participant models eventually made contact with the glenoid by 150° of humerothoracic elevation, although anatomic factors influenced the precise angle at which contact occurred. Clinical Relevance: Contact between the supraspinatus and the glenoid may occur frequently within the range of elevation required for overhead activities. Therefore, internal impingement may be a prevalent mechanism for rotator cuff deformation that could contribute to cuff pathology.

Stimulation Of

LI15 is an important acupuncture point to treat shoulder pain. There are 4 needling methods for LI15 in the textbook; 1 method requires the insertion of the needle horizontally between the acromion and the great tuberosity of the humerus with the arm lowered for supraspinatus tendonitis. This method is also applicable for all conditions of rotator cuff disease, but it has not previously been described in detail. Providing X-ray scans and describing needle direction and depth of insertion will provide evidence for needling with the arm down as an effective stimulation of the subacromial space. Firstly, for this technique, with the arm raised, a concave point is located between the front edge of the acromion and the humerus, and the lower upper arm. Secondly, the acupuncture needle is inserted slightly posteriorly towards the supraspinous fossa, in the direction of the supraspinatus tendon and to a depth of 30-40 mm.

Abstract Background The study aimed to explore the additional value of repair of Lafosse I subscapularis injury compared with debridement in anterosuperior rotator cuff injury. Methods The prospective study was conducted on a total of 41 patients with supraspinatus tendon tear combined with Lafosse I subscapularis injury. Eighteen patients were divided into the repair group and 23 patients were divided into the non-repair group. The two groups were compared for intraoperative parameters, pain score, range of motion of the shoulder joint, shoulder joint function and quality of life (QoL) at pre-operation, 3 and 6 months postoperatively and the final follow-up visit. Results The width of supraspinatus tendon tear did not exceed 3 cm and did not retract beyond the glenoid in among patients. There was no statistical difference of preoperative data between two groups, including age, course of disease, positive Jobe test, positive Bear-hug test, positive Lift-off test, Patte stage, longitudinal tear and pain severity (P > 0.05). Compared to preoperative levels, the severity of pain, ASES scores and EQ-5D-3L scores were significantly lower at 3 and 6 months postoperatively and the final position (P < 0.05). However, there was no statistical difference in pain severity, ASES scores and EQ-5D-3L scores between repair group and non-repair group (P > 0.05). Similarly, compared to preoperative levels, the range of motion of shoulder joint was significantly improved after operation, including internal rotation, external rotation, forward flexion and elevation (P < 0.05). However, there was no statistical difference in range of motion of shoulder joint between repair group and non-repair group (P > 0.05). Conclusion Operative treatment can effectively lessen severity of pain in the patients, improve shoulder joint function, increase the range of motion of the shoulder joint and enhance the QoL in treating anterosuperior rotator cuff injury. However, repair of subscapularis brings no benefit compared to debridement in treating supraspinatus tendon tear combined with Lafosse I subscapularis injury.
