Background: Anterior combined latissimus dorsi and teres major (aLDTM) tendon transfer has shown promise as a treatment for anterior superior irreparable rotator cuff tears (ASIRCTs). Our study aimed to compare aLDTM clinical outcomes for ASIRCTs between young and elderly patients. Methods: This retrospective study reviewed data from patients who underwent aLDTM tendon transfer for ASIRCTs with minimum 2-year follow-up. Clinical evaluations included visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), active range of motion (aROM), strength, and complications. Radiologic assessments included acromiohumeral distance, Hamada classification, and integrity of transferred tendon. Patients were divided into group total (all ages), group old (≥70 years), and group young (≤60 years). Results: A total of 123 patients were enrolled with 39 in group young (mean age, 56.6±4.9 years) and 27 in group old (mean age, 73.6±2.3 years). Postoperatively, both groups showed significant improvements in VAS, ASES, and SANE scores and improved aROM for forward elevation, abduction, and internal rotation. No significant differences in clinical coutcomes were noted between the groups. Furthermore, similar rates of complications, including retears and postoperative infections, were observed across all three groups. Conclusions Our study highlights the effectiveness of aLDTM transfer for ASIRCTs with minimal glenohumeral arthritis, demonstrating similar outcomes in both group young and group old patients. Moreover, patients in these distinct age groups showed comparable clinical results when compared to group total.Level of evidence: III.

Background: Irreparable anterosuperior rotator cuff tears (IASRCTs) present significant challenges, especially in young, active patients with limited joint-preserving options. Recently, latissimus dorsi (LD) transfer and combined latissimus dorsi and teres major (LDTM) transfer have gained attention as a potential surgical option. We aimed to compare the clinical and radiological outcomes of LD versus combined LDTM transfer in IASRCTs. Methods: In this retrospective comparative study, 53 patients with IASRCTs were analyzed after undergoing either LD transfer attached to lesser tuberosity (LT) (LD group, n = 23) or combined LDTM transfer attached to greater tuberosity (GT) (LDTM group, n = 30). Clinical evaluations included the visual analog scale score for pain, active shoulder range of motion (ROM), University of California Los Angeles Shoulder Score, American Shoulder and Elbow Surgeons score, activities of daily living that require active internal rotation (ADLIR) scores, and subscapularis (SSC)-specific examinations. Radiographic analyses involved assessing acromiohumeral distance (AHD), Hamada grade, the rate of anterior glenohumeral subluxation reduction, and integrity of the transferred tendon. Results: Postoperatively, both groups demonstrated significant improvements in pain and clinical scores (p < 0.001). At the 2-year follow-up, the LDTM group showed superior internal rotation strength (p < 0.001), ADLIR score (p = 0.017), and SSC-specific physical examination results (belly-press, p = 0.027; bear-hug, p = 0.031; lift-off, p = 0.032). No significant changes in AHD or Hamada grade were observed in either group. At final follow-up, no significant differences were found between the 2 groups in terms of AHD (p = 0.539) and Hamada grade (p = 0.974). Although preoperative anterior glenohumeral subluxation was improved in both groups, the LDTM group showed a statistically significantly higher rate of restoration compared to the LD group (p = 0.015). Conclusions While both LD and combined LDTM transfers for IASRCTs improved postoperative pain relief, clinical scores, and active ROM, the combined LDTM transfer attached to GT was superior to LD transfer attached to LT in terms of internal rotational strength, ADLIR score, and SSC-specific examinations. Neither group showed significant progress in cuff tear arthropathy or decreased AHD at 2-year follow-up; however, the combined LDTM transfer notably improved preoperative anterior glenohumeral subluxation.

OBJECTIVES: The purpose of this study was to observe the change in the viscoelastic properties of thermoplasticized injectable root canal filling materials as a function of temperature and to compare the handling characteristics of these materials. MATERIALS AND METHODS: Three commercial gutta perchas and Resilon (Pentron Clinical Technologies) in a pellet form were heated in the Obtura-II system (Obtura Spartan) at 140degrees C and 200degrees C, and the extrusion temperature of the thermoplasticized materials was measured. The viscoelastic properties of the materials as a function of temperature were evaluated using a rheometer. The elastic modulus G', viscous modulus G", loss tangent tandelta, and complex viscosity eta* were determined. The phase transition temperature was determined by both the rheometer and a differential scanning calorimeter (DSC). The consistency of the materials was compared under compacting pressure at 60degrees C and 40degrees C by a squeeze test. RESULTS: The three gutta perchas had dissimilar profiles in viscoelastic properties with varying temperature. The phase transition of softened materials into solidification occurred at 40degrees C to 50degrees C, and the onset temperatures obtained by a rheometer and a DSC were similar to each other. The onset temperature of phase transition and the consistency upon compaction pressure were different among the materials (p < 0.05). Resilon had a rheologically similar pattern to the gutta perchas, and was featured between high and low-flow gutta perchas. CONCLUSIONS: The rheological characteristics of the thermoplasticized root canal filling materials changed under a cooling process. The dissimilar viscoelastic properties among the materials require different handling characteristics during an injecting and compacting procedure.
