Does humeral fixation technique affect long-term outcomes of total shoulder arthroplasty?
Background For anatomic total arthroscopic repair, cementless humeral fixation has recently gained popularity. However, few studies have compared clinical, radiographic, and patient-reported outcomes between cemented and press-fit humeral fixation, and none have performed follow-up for longer than 5 years. In this study, we compared long-term postoperative outcomes in patients receiving a cemented versus press-fit humeral stem anatomic arthroscopic repair. Methods This study retrospectively analyzed 169 shoulders that required primary anatomic total shoulder arthroplasty (aTSA). Shoulders were stratified by humeral stem fixation technique: cementation or press-fit. Data were collected pre- and postoperatively. Primary outcome measures included range of motion, patient reported outcomes, and radiographic measures. Results One hundred thirty-eight cemented humeral stems and 31 press-fit stems were included. Significant improvements in range of motion were seen in all aTSA patients with no significant differences between final cemented and press-fit stems (forward elevation: P=0.12, external rotation: P=0.60, and internal rotation: P=0.77). Patient reported outcome metrics also exhibited sustained improvement through final follow-up. However, at final follow-up, the press-fit stem cohort had significantly better overall scores when compared to the cemented cohort (visual analog score: P=0.04, American Shoulder and Elbow Surgeon Score: P<0.01, Simple Shoulder Test score: P=0.03). Humeral radiolucency was noted in two cemented implants and one press-fit implant. No significant differences in implant survival were observed between the two cohorts (P=0.75). Conclusions In this series, we found that irrespective of humeral fixation technique, aTSA significantly improves shoulder function. However, within this cohort, press-fit stems provided significantly better outcomes than cemented stems in terms of patient reported outcome scores. Level of evidenceIII
Evaluating the effects of age on the long-term functional outcomes following anatomic total shoulder arthroplasty
Background In the past decade, the number of anatomic total shoulder arthroplasty (aTSA) procedures has steadily increased. Patients over 65 years of age comprise the vast majority of recipients, and outcomes have been well documented; however, patients are opting for definitive surgical treatment at younger ages.We aim to report on the effects of age on the long-term clinical outcomes following aTSA. Methods Among the patients who underwent TSA, 119 shoulders were retrospectively analyzed. Preoperative and postoperative clinical outcome data were collected. Linear regression analysis (univariate and multivariate) was conducted to evaluate the associations of clinical outcomes with age. Kaplan-Meier curves and Cox regression analyses were performed to evaluate implant survival. Results At final follow-up, patients of all ages undergoing aTSA experienced significant and sustained improvements in all primary outcome measures compared with preoperative values. Based on multivariate analysis, age at the time of surgery was a significant predictor of postoperative outcomes. Excellent implant survival was observed over the course of this study, and Cox regression survival analysis indicated age and sex to not be associated with an increased risk of implant failure. Conclusions When controlling for sex and follow-up duration, older age was associated with significantly better patient-reported outcome measures. Despite this difference, we noted no significant effects on range of motion or implant survival. Level of evidenceIV
Shoulder Injury Related to Vaccine Administration: Case Series
Abstract Objective Shoulder pain is a common presentation in the primary care setting, and shoulder pain after vaccination has a growing body of literature. The present study sought to understand how a standardized treatment protocol would aid patients experiencing shoulder injury related to vaccine administration (SIRVA). Methods Patients experiencing SIRVA were retrospectively recruited between February 2017 and February 2021. All patients were treated with physical therapy and offered a cortisone injection. Post-treatment range of motion (i.e., forward elevation, external rotation, internal rotation) and patientsâ reported outcomes were collected with the visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), simple shoulder test (SST), and single assessment numeric evaluation (SANE) scores. Results A total of 9 patients were retrospectively examined. Among them, 6 patients presented within one month of a recent vaccination event, while 3 patients presented 67, 87, and 120 days after vaccination. Furthermore, 8 of the patients completed physical therapy, and 6 of them underwent a cortisone injection. The follow-up time averaged 8 months. At final follow-up, the mean external rotation was 61Âș (standard deviation, SD±3Âș) and the mean forward elevation was 179Âș (SD±45Âș). Internal rotation ranged between L3 and T10. The VAS pain scores were 3.5/10.0 (SD±2.4), the mean ASES score was 63.5/100.0 (SD±26.3), and the SST scores were 8.5/12.0 (SD±3.9). Finally, the SANE scores were 75.7/100.0 (SD±24.7) and 95.7/100.0 (SD±6.1) in the injured and contralateral shoulders respectively. Conclusion Shoulder pain after a vaccination treated with physical therapy and cortisone injection ultimately resulted in favorable shoulder range of motion and functional score outcomes.

Humeral head hemiarthroplasty for patients with avascular necrosis following a solid organ transplant: A report of three shoulders
Background: Avascular necrosis (AVN) is a common occurrence following solid organ transplant (SOT) due to chronic steroid use. We report on three shoulders of humeral head hemiarthroplasty (HHA) in the setting of AVN after SOT. This topic is an important issue to study as there is limited literature on AVN requiring shoulder arthroplasty following SOT. As the prevalence of SOT continues to rise, it is important to study this population before making guidelines in the future. Case presentations: In one shoulder, a 51-year-old male presented with AVN of the left shoulder three years after undergoing a lung transplant and taking 5mg oral prednisone daily. In the second and third shoulder, a 61-year-old female presented with AVN of bilateral shoulders two years after undergoing a kidney transplant and taking 7.5mg oral prednisone daily. All three shoulders went on to have HHA with improved outcomes after surgery at a mean follow-up of 4.6 years. Conclusion: Shoulder arthroplasty is safe and effective for patients with avascular necrosis after a SOT
Outcomes for reverse total shoulder arthroplasty patients at an average of 11.6 Years follow-up: A case series
Background: Reverse total shoulder arthroplasty (rTSA) is a relatively new procedure, only gaining approval in the United States in 2003. For these reasons, we sought to expand upon the breadth of current literature reporting on the long-term outcomes following this increasingly common orthopedic procedure. Case details: An institutional database was utilized to identify patients who underwent rTSA with a minimum postoperative follow-up of ten years. The five patients with the longest follow-up and complete clinical measures were ultimately included. Demographics, patient reported outcomes (Visual Analog Score (VAS), American Shoulder and Elbow Surgeon (ASES), Simple Shoulder Test (SST)), range of motion (Forward Elevation, Internal Rotation, External Rotation), and various radiographic measures were subsequently analyzed. The mean follow-up time was 11.6 ± 1.7 years. Patients saw improvements in VAS (pre-op.: 4.8 vs post-op: 3.2), ASES (pre-op.: 38.0 vs post-op: 58.0), SST (pre-op.: 2.6 vs post-op: 5.4), and Forward Elevation (pre-op.: 124° vs post-op: 142°) scores. However, internal and external rotation decreased by two vertebral levels and 14°, respectively. Only one shoulder failed during this follow-up time requiring revision surgery at 5.8 years. The overall survival was 100.0% and 80.0% at five- and ten-years follow-up, respectively, with a predicted implant survival time of 12.8 ± 1.6 years. Conclusion: Despite its relative novelty, rTSA is proving to be a sustainable procedure for patients with regards to pain, shoulder functionality, and implant survival, however, range of motion may not be completely restored. Overall, rTSA acts as a viable option for patients requiring shoulder replacement
Arthroscopic Onlay Articular Margin Biceps Tenodesis for Long Head of the Biceps Tendon Pathology
The long head of the biceps (LHB) tendon is a common source of shoulder pain. LHB tendon pathology typically occurs with concomitant rotator cuff or labrum injuries but can occasionally occur in isolation as biceps tendinopathy or rupture. Tenodesis has been increasingly used to treat LHB tendon pathology, and numerous techniques have been developed that vary in approach, fixation construct, and fixation location. In this Technical Note, we describe an arthroscopic onlay articular margin biceps tenodesis with suture anchors. This technique has several advantages, namely intra-articular visualization of the tenodesis, strong fixation to high density bone of the articular margin, and most importantly, preservation of the anatomic lengthâtension relationship
Emerging Technologies in the Treatment of Adult Spinal Deformity
Outcomes for adult spinal deformity continue to improve as new technologies become integrated into clinical practice. Machine learning, robot-guided spinal surgery, and patient-specific rods are tools that are being used to improve preoperative planning and patient satisfaction. Machine learning can be used to predict complications, readmissions, and generate postoperative radiographs which can be shown to patients to guide discussions about surgery. Robot-guided spinal surgery is a rapidly growing field showing signs of greater accuracy in screw placement during surgery. Patient-specific rods offer improved outcomes through higher correction rates and decreased rates of rod breakage while decreasing operative time. The objective of this review is to evaluate trends in the literature about machine learning, robot-guided spinal surgery, and patient-specific rods in the treatment of adult spinal deformity
Arthroscopic Remplissage for Anterior Shoulder Instability
Background: There are several approaches such as the Bankart repair, Latarjet, and Remplissage to treat recurrent glenohumeral instability. Indications: We chose to augment an arthroscopic Bankart repair with a Remplissage in this 26-year-old patient given the presence of a Hill-Sachs lesion, history of recurrent shoulder dislocations, and young age of the patient. Technique Description: We established four portals using previously well-documented techniques. The Hill-Sachs lesion was evaluated using the anterosuperior portal. Two anchors were placed, one on both the superior and inferior aspects of the Hill-Sachs lesion. The sutures were shuttled through the knotless anchor mechanism and tensioned after confirming the cannula was through the deltoid. Then, we completed the Remplissage by repairing the infraspinatus tendon and capsule into the posterior humeral head. Results: The Remplissage procedure is very successful at reducing recurrent instability in young, active patients. Previous studies have reported very low rates, even 0% recurrent instability, after surgery with 80% to 90% of patients returning to sports. Studies have also documented excellent patient-reported outcomes at short- to mid-term follow-up. Complication rates are historically lower when the Remplissage is done with an arthroscopic Bankart repair than the Bankart repair alone. Discussion/Conclusion: The Remplissage procedure is a safe, effective option at reducing future instances of shoulder dislocations in conjunction with Bankart repairs. Patients can expect to return to their active lifestyles, with many patients achieving the same level of activity as before the initial shoulder dislocation.
