Purpose: The relationship between retear that may occur after rotator cuff repair and patient satisfaction is not well established. This study aimed to determine whether the types and size of the retear evaluated by computed tomography arthrography (CTA) influenced patient satisfaction. We also analyzed the patient factors that could affect patient satisfaction. Patients and methods: A total of 50 patients who were diagnosed with rotator cuff retear after undergoing arthroscopic rotator cuff repair were included in this study. All the patients were dichotomously classified into the satisfactory or dissatisfactory groups according to the patients' self-classifications. CTA was used to assess the attachment status of the footprint, detect retear on the medial side of the footprint of the repaired cuff, and determine the retear size. Demographic factors, including sex, age, occupation, dominant upper extremity, duration of pain, presence of diabetes mellitus, trauma history, history of ipsilateral shoulder surgery, repair technique, worker's compensation status, and functional shoulder score, were investigated. Results: Thirty-nine patients were classified into the satisfactory group and 11 patients were classified into the dissatisfactory group. There were no differences in age, sex, occupation, dominant hand, duration of pain, presence of diabetes mellitus, trauma history, history of ipsilateral shoulder surgery, repair technique, worker's compensation, and duration of follow-up between the two groups. However, the postoperative American Shoulder and Elbow Surgeon (ASES) score (P < 0.01), visual analog scale (VAS) pain level (P < 0.01), anteroposterior (AP) length (P < 0.01), and area of the retear site (P < 0.01) were significantly different. Conclusion: The AP length and area of the retear site estimated using CTA were confirmed as the significant risk factors for dissatisfaction. However, the type of repaired rotator cuff judged by the attachment status of the footprint did not correlate with patient satisfaction. In addition, the postoperative VAS pain scale and ASES score was correlated with patient satisfaction. [ABSTRACT FROM AUTHOR]

Background: Acromioclavicular joint fixation using a hook plate is effective for the treatment of acute acromioclavicular joint dislocation. However, several studies have reported some complications including loss of reduction after surgery for acromioclavicular joint dislocation. This study aimed to identify the risk factors associated with the loss of reduction after acromioclavicular joint dislocation surgery using a hook plate. Methods: This was a retrospective study that assessed 118 patients with acromioclavicular joint dislocation, who were diagnosed between March 2013 and January 2019 and underwent surgical treatment using the hook plate (reduction loss group: n = 38; maintenance group: n = 80). The mean follow-up period was 29.9 months (range, 24–40 months). We assessed the range of motion, the American Shoulder and Elbow Surgeons score (ASES), visual analog scale score for pain, and a subjective shoulder value. Radiological assessment of coracoid clavicular distance was performed. The risk factors of reduction loss were analyzed using multivariable logistic regression analysis. Results: Age (p = 0.049), sex (female, p = 0.03, odds ratio OR = 4.81), Rockwood type V (p = 0.049, OR = 2.20), and time from injury to surgery > 7 days (p = 0.018, OR = 2.59) were statistically significant factors in the reduction loss group. There were no significant differences in the clinical outcomes for range of motion, ASES, subjective shoulder value, and visual analog scale scores between the two groups. In the radiological results, preoperative coracoid clavicular distance (p = 0.039) and ratio (p = 0.001), and over-reduction (p = 0.023, OR = 0.40) were significantly different between the two groups. The multivariate logistic regression analysis identified the female sex (p = 0.037, OR = 5.88), a time from injury to surgery > 7 days (p = 0.019, OR = 3.36), and the preoperative coracoid clavicular displacement ratio of the injured shoulder (p < 0.001, OR = 1.03) as risk factors associated with reduction loss following surgery using a hook plate for acromioclavicular dislocation. Conclusion: A delayed timing of surgery > 7 days, preoperative coracoid clavicular displacement ratio of the injured shoulder, and female sex were identified as risk factors for loss of reduction after surgery using a hook plate for acromioclavicular joint dislocation.

Background: To compare shoulder morbidity between patients who received transverse rectus abdominis myocutaneous (TRAM) flaps after mastectomy (MX + TRAM) and patients who underwent mastectomy only (MX). Methods: Thirty patients in each group were followed for a minimum of 2 postoperative years. Visual analog scale (VAS) score, restricted range of motion (ROM), rotator cuff disease, muscle strength, shoulder function scores (American Shoulder and Elbow Score and Shoulder Pain and Disability Index), measurement of scapular tilt on chest radiography and standing position in each group were compared. Results: There were no significant differences in VAS, restricted ROM, rotator cuff disease, muscle strength, shoulder function scores or scapula tilt on physical examination. However, lower angles of the scapula on chest radiography (4.0 ± 13.2 versus −3.4 ± 12.4 mm; P = 0.029) and pectoralis minor index (0.4 ± 7.7 mm versus 7.8 ± 9.1 mm; P = 0.001) were significantly different between the two groups. Conclusions: Immediate breast reconstruction after a MX had advantages for preserving scapular resting alignment but did not provide benefits for shoulder morbidity on short‐term follow‐up.

Purpose: This paper analyzed outcomes of the osteosynthesis with a locking plate system for the fractures of the humerus in throwers using the anterior humeral approach.Methods: Retrospective case series including 31 patients. Bone union was assessed through follow-up radiographs. Results of visual analogue scale (VAS) for pain, range of motion in the elbow joint, time of return to work, and the Mayo Elbow Performance Score (MEPS) were evaluated to determine functional outcomes. Direction and length of the fracture, the distal cortical length, the humeral diameter, and the total humeral length were measured as part of fracture configuration analysis.Results: Mean patient age was 25.8 (range, 18-34) years. The follow-up average was 16.0 months (range, 12-23). Delayed union was observed in one (3.1 %) patient. Mean final VAS was 0.4 (range, 0-2), mean time of return to work was 18.2 weeks (range, 13-36), and mean MEPS was 96.3 (range, 88-100) points. All fractures showed a spiral configuration. Mean fracture length was 79.7 (95 % CI, 72.6-86.7) mm, and mean distal cortical length was 48.3 (95 % CI, 37.8-58.8) mm.Conclusions: The results of the current study indicates that plate osteosynthesis using a locking plate system combined with interfragmentary lag screws through anterior humeral approach may be a favorable option for the surgical treatment of humeral shaft fractures in throwers.

Background: Suture bridge repair has been recognized to have superior biomechanical characteristics, as shown in previous biomechanical studies. However, it is not clear whether the tendon heals better in vivo after suture bridge repair.Purpose: To evaluate the clinical results and repair integrity after arthroscopic rotator cuff repair using a suture bridge technique for patients with rotator cuff tears.Study Design: Case series; Level of evidence, 4.Methods: One hundred twenty-three shoulders (120 patients) that underwent arthroscopic suture bridge repair for full-thickness rotator cuff tear were enrolled for this study. The mean duration of follow-up was 25.2 months (range, 16-34 months). The postoperative repair integrity was analyzed with use of magnetic resonance imaging (MRI) in 87 shoulders. According to the retear patterns on postoperative MRI, the cases were divided into type 1 (failure at the original repair site) or 2 (failure around the medial row).Results: At the last follow-up, the University of California at Los Angeles (UCLA) score improved from the preoperative mean of 13.2 points to 29.7 points (P < .001). The rotator cuff was completely healed in 58 (66.7%) of the 87 shoulders, and there was a recurrent tear in 29 shoulders (33.3%). The incidence of retear tended to increase with age older than 60 years at the time of surgery (P = .002). When there was a larger intraoperative tear, the rate of retear was also higher (P = .002). When the severity of preoperative fatty degeneration of the cuff muscles was higher, there was a greater chance of a recurrent tear (P < .001). The retear patterns on postoperative MRI in 29 shoulders with recurrent failures were classified as type 1 in 12 shoulders (41.4%) and type 2 in 17 shoulders (58.6%). The preoperative cuff tear size did not have an influence on retear patterns (P = .236), but the percentage of type 1 retear increased with the severity of fatty degeneration or muscle atrophy (P = .041, .023).Conclusion: Arthroscopic suture bridge repair of full-thickness rotator cuff tears led to a relatively high rate of recurrent defects. However, the mean 25-month follow-up demonstrated excellent pain relief and improvement in the ability to perform the activities of daily living, despite the structural failures. The factors affecting tendon healing were the patient’s age, the size and extent of the tear, and the presence of fatty degeneration in the rotator cuff muscle. The retear in cases with a suture bridge technique tended to be more frequently at the musculotendinous junction. [ABSTRACT FROM PUBLISHER]
