Project description:IntroductionThe ability to provide reliable outcomes in treatment of patients with degenerative rotator cuff tears has become increasingly complicated, as a result of more advanced disease and the increased array of treatment choices.Step 1 preoperative planningDevelop and communicate with a consistent team of interdisciplinary physicians both preoperatively and postoperatively; utilize advanced imaging modalities to evaluate muscle atrophy as well as glenoid and humeral bone stock.Step 2 patient positioningPlace the patient in a beach-chair position, check the abdominal strap, and position yourself facing the axilla.Step 3 surgical approachDevelop the subdeltoid and subacromial spaces and take care to avoid vigorous over-retraction of the deltoid.Step 4 humeral exposure and preparationPerform the head cut utilizing the 135° resection guide, broach the humerus, and ream the humeral socket.Step 5 glenoid exposure and preparation glenosphere insertionReam the inferior surface to bleeding subchondral bone; bleeding subchondral bone on the inferior 50% of the prepared glenoid surface indicates a sufficient depth.Step 6 final humeral preparationAt final reaming, the edge of the reamer should sit flush with the cut surface of the humerus.Step 7 trialingProper soft-tissue balance is frequently achieved by positioning the humeral component so that the rim of the socket lies just above the humeral osteotomy site at the anatomic neck.Step 8 component implantation and closureWhen cementing the humeral component, the socket should match the reamed proximal part of the humerus.ResultsInitially, reverse shoulder arthroplasty was primarily used to treat osteoarthritis of the glenohumeral joint resulting from chronic rotator cuff deficiency or for true rotator cuff tear arthropathy.What to watch forIndications Contraindications Pitfalls & Challenges.

Project description:We aimed to estimate the interrelation between preoperative deltoid muscle status by measuring the 3-dimensional deltoid muscle volume and postoperative functional outcomes after reverse total shoulder arthroplasty(RTSA). Thirty-five patients who underwent RTSA participated in this study. All patients underwent preoperative magnetic resonance imaging(MRI) as well as pre- and postoperative radiography and various functional outcome evaluations at least 1 year. The primary outcome parameter was set as age- and sex-matched Constant scores. The 3-dimensional deltoid muscle model was generated using a medical image processing software and in-house code, and the deltoid muscle volume was calculated automatically. Various clinical and radiographic factors comprising the deltoid muscle volume adjusted for body mass index(BMI) were analyzed, and their interrelation with the outcome parameters was appraised using a multivariate analysis. As a result, all practical consequences considerably improved following surgery(all p<0.01). Overall, 20 and 15 indicated a higher and a lower practical consequence than the average, respectively, which was assessed by the matched Constant scores. The deltoid muscle volume adjusted for BMI(p = 0.009), absence of a subscapularis complete tear (p = 0.040), and greater change in acromion-deltoid tuberosity distance(p = 0.013) were associated with higher matched Constant scores. Multivariate analysis indicated that the deltoid muscle volume was the single independent prognostic factor for practical consequences(p = 0.011). In conclusion, the preoperative deltoid muscle volume significantly affected the functional outcome following RTSA in patients with cuff tear arthropathy or irreparable cuff tears. Therefore, more attention should be paid to patients with severe atrophied deltoid muscle who are at a high risk for poor practical consequences subsequent to RTSA.

Project description:An irreparable anterosuperior massive rotator cuff tear with an irreparable subscapularis tear is not common; however, once symptomatic, it would become a challenging situation. Tendon transfer is a choice and the pectoralis major is a commonly selected graft source. However, there are theoretical concerns over its use: high invasiveness and low reproducibility, different force vector from the subscapularis, unsuitability for the arthroscopic modification, and difficulty in conversion to the reverse shoulder arthroplasty due to adhesions and scar formation in the anterior shoulder. Recently, open pectoralis minor transfer has been advocated as an alternative reconstruction option. We describe an arthroscopic-assisted technique of pectoralis minor transfer for irreparable anterosuperior massive rotator cuff tear.

Project description:Latissimus dorsi tendon transfer is an effective option for young and active patients with massive irreparable posterosuperior rotator cuff tears and intact subscapularis tendon. This approach has been shown to relieve pain and improve shoulder function in both the short and long term. We describe a surgical technique using an acromial osteotomy to better expose the greater tuberosity for the tendon transfer without disrupting the deltoid muscle. The latissimus dorsi tendon is reinforced with a human dermal collagen matrix (GraftJacket; Wright Medical Group) for additional augmentation of the muscle to gain more excursion for the tendon transfer to the greater tuberosity. The transferred tendon is fixed to the supraspinatus and infraspinatus footprints on the greater tuberosity using suture anchors. The acromial osteotomy is repaired back anatomically with several No. 5 braided sutures (FiberWire; Arthrex).

Project description:Irreparable posterior-superior rotator cuff tear is encountered quite often in clinical practice. Bridging the tendon defect with various materials is reasonable. However, optimal bridging structures and techniques are still being pursued. We introduce a rotator cuff bridging technique, rooting rotator cuff reconstruction. In this technique, autogenous tendon is used to make grafts. On the medial side, the graft tendons are suspended on the rotator cuff tendon. On the lateral side, the graft tendons are placed into tunnels through the tuberosities. The most critical steps of this technique are properly fabricating the humeral tunnels and suspending the graft tendons onto the rotator cuff tendon. We believe this technique will shed light on rotator cuff reconstruction.

Project description:Despite the different treatment options for irreparable and massive rotator cuff tears (RCTs), there is no optimal treatment. Thirty percent of total RCTs can be classified as irreparable because of the massive tear size and severe muscle atrophy. The reported treatment failure rate is approximately 40% for massive RCTs. RCTs may be treated conservatively or surgically depending on pain, disability, and functional demands. The surgical treatment options are many, but decision making is a challenge; the real challenge is to apply the correct procedure for the correct indication in each patient. The long head of the biceps tendon (LHBT) was used for augmentation to bridge the gap in immobile, massive RCTs. An arthroscopic biceps-incorporating technique was used for repair of large and massive RCTs, avoiding undue tension on the rotator cuff (RC). Recently, the LHBT was used for superior capsular reconstruction. This article describes the use of the LHBT for reconstruction of massive and irreparable RCTs through the following steps: (1) open exposure of the RCT, (2) debridement and subacromial decompression, (3) biceps tenotomy at the LHBT's origin on the glenoid, (4) LHBT and RC cuff mobilization, (5) passage of the LHBT through the mobilized RC and reflection onto itself, (6) tuberoplasty, and (7) fixation of the RC complex at the RC footprint.

Project description:Massive, irreparable rotator cuff tears are challenging to treat and associated with pain and severe limitation in shoulder elevation due to the proximal migration of the humeral head and, consequently, subacromial impingement. Furthermore, retraction of the tendons in combination with fat infiltration and muscular weakness results in unpredictable treatment outcomes. While conservative treatment may be warranted for low-demand patients, surgical treatment is often indicated for a successful return to activities of daily living as well as an improved quality of life. The reported failure rate of rotator cuff repair for the treatment of a massive rotator cuff tear varies. However, this failure is often found at the interface between the tendon and tendon footprint. Several techniques have been reported to address this pathology, including muscular transfer, arthroscopic debridement, augmentation procedures, and superior capsule reconstruction. In particular, superior capsule reconstruction has been reported as a safe and effective method to treat a massive, irreparable rotator cuff tear. The purpose of this Technical Note is to describe our preferred technique of a superior capsule reconstruction for the treatment of a massive, irreparable rotator cuff tear.

Project description:Massive irreparable rotator cuff tears have been troublesome entities to treat, especially in younger patients. Few good options exist, leaving most patients in recent years receiving a reverse total shoulder arthroplasty. Reverse shoulder arthroplasty carries serious risks, a limited lifespan, and no other viable options should it fail. Recent biomechanical studies have shown that the superior capsule is critical to containing the glenohumeral joint reduced, allowing the larger muscles like the deltoid and pectoralis major to function properly. The superior capsular reconstruction is an anatomic reconstruction of the superior capsule to restore the normal restraint to superior translation that occurs with a deficient rotator cuff. The technique described in this article is an arthroscopic reconstruction of the superior capsule with dermal allograft.

Project description:Several treatment options for chronic, massive rotator cuff tears exist, and they include debridement with possible biceps tenotomy or tenodesis, open or arthroscopic partial repair, muscle or tendon transfer, superior capsule reconstruction, synthetic patch augmentation, and reverse total shoulder arthroplasty. The aim of this technique article is to describe our preferred surgical option for irreparable, massive rotator cuff tears with an irreparable supraspinatus, a reparable infraspinatus, and an intact or reparable subscapularis tendon.

Project description:Background and hypothesisThe impact of preoperative fatty infiltration of specific rotator cuff muscles on the outcomes of reverse total shoulder arthroplasty (rTSA) has not been well defined. Preoperative fatty infiltration of the shoulder musculature will negatively affect rTSA outcomes.MethodsA comprehensive literature review was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses using PubMed, Embase, OVID Medline, Scopus, Cinahl, Web of Science, and Cochrane databases for original, English-language studies evaluating effect of fatty infiltration of shoulder musculature on rTSA outcomes published from January 1, 2000 to present. Blinded reviewers conducted multiple screens. All included studies were graded based on the level of evidence, and data concerning patient demographics and postoperative outcomes were extracted.ResultsA total of 11 articles were included, including one level I article, three level III articles, and seven level IV articles. The review consisted of 720 patients and 731 shoulders (320 women and 157 men), with a mean age of 72.4 years. A single deltopectoral approach was performed for a majority of studies (627/731 shoulders), followed by a superolateral approach (70/731 shoulders) and a single transdeltoid approach (4/731 patients). Eleven studies reported data specifically about preoperative fatty infiltration of the rotator cuff musculature; the teres minor was studied most widely (298/731 shoulders), followed by the subscapularis (256/731 shoulders) and infraspinatus (232/731 shoulders). The Constant score (562/731 shoulders) and American Shoulder and Elbow Surgeons score (284/731 shoulders) were the most common recorded outcome scores. Fatty infiltration of the teres minor, supraspinatus, and infraspinatus was associated with worse range of motion after rTSA.ConclusionPreoperative fatty infiltration of the rotator cuff, particularly of the teres minor and infraspinatus, has a negative impact on subjective patient outcomes and restoration of range of motion, especially external rotation, after rTSA. The impact of fatty infiltration of the other rotator cuff muscles remains unclear, which may be due to intersurgeon differences in the handling of the remaining rotator cuff muscles or differences in implant design. The evaluated literature provides information on which patients can be educated about probable outcomes and restoration of function after rTSA.
