Abstract

Background Advanced practice physiotherapy has emerged as a promising solution to improve health care access because access to orthopedic care is limited in several countries. However, evidence supporting advanced practice physiotherapy models for the management of shoulder pain remains scarce. The purpose of this study was to establish diagnostic, surgical triage, and medical imaging agreement between advanced practice physiotherapists (APPs) and orthopedic surgeons (OSs) for the management of patients with shoulder disorders in an outpatient orthopedic clinic. Methods Patients referred to an OS for shoulder complaints were recruited and independently assessed by an OS and an APP. Each provider completed a standardized form indicating diagnosis, imaging test requests, and triage of surgical candidates. Patient satisfaction with care was recorded with the 9-item Visit-Specific Satisfaction Questionnaire (VSQ-9). Inter-rater concordance was calculated with the Cohen κ, prevalence-adjusted bias-adjusted κ, and associated 95% confidence interval (CI). We used χ2 tests to compare differences between providers in terms of treatment plan options and Student t tests to compare patient satisfaction between providers. Results Fifty participants were evaluated. Good diagnostic agreement was observed between providers (κ, 0.80; 95% CI, 0.67-0.93). Agreement for triage of surgical candidates was moderate (κ, 0.46; 95% CI, 0.21-0.71) as APPs tended to refer patients more often to OSs for further evaluation. Imaging test request agreement was moderate as well (κ, 0.42; 95% CI, 0.19-0.66). Patient satisfaction with care was high, with no significant differences found between providers (P = .70). Conclusion APPs could improve access to orthopedic care for shoulder disorders by safely initiating patient care without compromising satisfaction. These results support further development and evaluation of APP care for orthopedic patients presenting with shoulder disorders.

Many factors play a role in getting a successful outcome after shoulder arthroplasty such as soft-tissue tensioning, component version, and subscapularis healing. This article focuses primarily on component version in both anatomic and reverse shoulder replacement and how it relates to stability, function, and outcome.

Abstract

Summary Caloric restriction (CR) is standard lifestyle therapy in obesity management. CR-induced weight loss improves the metabolic profile of individuals with obesity. In mice, occurrence of beige fat cells in white fat depots favors a metabolically healthy phenotype, and CR promotes browning of white adipose tissue (WAT). Here, human subcutaneous abdominal WAT samples were analyzed in 289 individuals with obesity following a two-phase dietary intervention consisting of an 8 week very low calorie diet and a 6-month weight-maintenance phase. Before the intervention, we show sex differences and seasonal variation, with higher expression of brown and beige markers in women with obesity and during winter, respectively. The very low calorie diet resulted in decreased browning of subcutaneous abdominal WAT. During the whole dietary intervention, evolution of body fat and insulin resistance was independent of changes in brown and beige fat markers. These data suggest that diet-induced effects on body fat and insulin resistance are independent of subcutaneous abdominal WAT browning in people with obesity.

Abstract

Proximal humerus fracture treatment has evolved considerably in the recent years. Fewer hemiarthroplasties are being done than in the past. The goal of this chapter is to look for alternatives to reverse total shoulder replacement and to consider what is the best treatment for four-part proximal humerus fractures in active and healthy 65 year-old patients.

Abstract

Background This study biomechanically compares two methods of supraspinatus repair: single row transosseous braided-tape (BT) and suture bridge transosseous equivalent (SBTE) with 2 medial anchors and 2 lateral anchors. The purpose is to test the hypothesis that BT provides superior or equal biomechanical strength compared to SBTE. Methods Nine pairs of frozen cadaveric shoulders were selected and both repair techniques were tested on each pair, using a biomechanical testing unit to measure cyclic loading and ultimate load to failure. Moreover, tendon displacement was measured using the percentage of footprint exposed during the cyclic loading phase. Results Mean specimen age was 71 years (6 males, 3 females), and mean volumetric bone mineral density was 134 mg/cm 3 . BT mean ultimate load was 266 ± 81 Newton (N) compared to 398 ± 69 N for SBTE and this difference of 131 N was statistically significant p = 0.025. There was a strong positive correlation between bone mineral density and SBTE construct ultimate load. The difference between the percentage of footprint exposed after cyclic loading of the two repairs was statistically significant with the exception of the 10–80 N load (p Conclusion SBTE repair with bone anchors provides superior biomechanical strength compared to BT repair in terms of ultimate load and cyclic loading. The tendon-suture junction is the weakness of both methods. These models simulate a complete tear with total loss of contact with rotator interval and infraspinatus. Future studies could focus on a more isolated physiologic supraspinatus tear pattern. Level of Evidence Basic science study (Level II).

Abstract

Background To help determine the optimal fixation method for subscapularis tendon repair in arthroplasty, the present study compares single-passage transosseous tape (BT) and modified Mason-Allen #2 suture (MA). Methods Eighteen human cadaveric shoulders were randomized to two repair constructs after arthroplasty preparation. Both techniques included two transosseous passages through the bicipital groove and then through the tendon at the level of the anatomical neck. Construct was tested using a traction machine, measuring cyclic loading and ultimate load to failure. Results The mean age of our specimens was 71 years. No significant difference was observed between the repair techniques in both mean ultimate load and cyclic loading. The mean (SD) ultimate load (UL) for BT was 293 (84) N and 342 (117) N for MA, which was not statistically significant ( p = 0.374). The majority of repairs failed in the tendon. Bone cut-out was observed with the MA but not for the BT repair. No correlation was found between bone density and UL for BT ( r = −0.09) but there was strong correlation for MA ( r = 0.63). Conclusions The MA repair appears to be more dependant on bone mineral density for ultimate load, indicating that braided-tape might be better suited for osteoporotic patients to avoid bone cut-out.
