Randomized Controlled Trial Multicenter StudyReverse total shoulder arthroplasty provides better shoulder function than hemiarthroplasty for displaced 3- and 4-part proximal humeral fractures in patients aged 70 years or older: a multicenter randomized controlled trial.
The most appropriate treatment for displaced multiple-fragment proximal humeral fractures in elderly patients is currently unclear. Reverse total shoulder arthroplasty (rTSA) is a promising treatment option that is being used increasingly. The purpose of this study was to compare the outcome of rTSA vs. hemiarthroplasty (HA) for the treatment of displaced 3- and 4-part fractures in elderly patients. ⋯ We found that rTSA provides better shoulder function than HA as measured with the Constant score, further emphasized by rTSA patients being more satisfied with their shoulder function. The difference appears to be mainly a result of better range of motion (abduction and flexion) in the rTSA group. The results also indicate that patients aged ≥ 80 years benefit less from rTSA than patients aged 70-79 years.

Multicenter Study Comparative StudyComparison of complication types and rates associated with anatomic and reverse total shoulder arthroplasty.
Complications after anatomic (aTSA) and reverse (rTSA) total shoulder arthroplasty can be devastating to a patient's quality of life and require revisions that are costly to both the patient and the health care system. The purpose of this study is to determine the types, incidence, and timing of complications following aTSA and rTSA using an international database of patients who received a single-platform total shoulder arthroplasty system, in order to quantify the types of failure modes and the differences that occur between aTSA and rTSA. ⋯ This large database analysis quantified complication and revision rates for aTSA and rTSA. We found aTSA and rTSA complication rates of 10.7% and 8.9%, respectively; with revision surgery rates of 5.6% and 2.5%, respectively. The 2 most common complications for each prosthesis type (aTSA: subscapularis/rotator cuff tears, aseptic glenoid loosening; rTSA: acromial/scapular fractures, instability) were unique to each device. The rate of infection was similar for both. Future prosthesis and technique development should work to mitigate these common complication types in order to reduce their rate of occurrence.

Multicenter StudyThe effect of body mass index on internal rotation and function following anatomic and reverse total shoulder arthroplasty.
The exact relationship between body mass index (BMI) and internal rotation (IR) before and after total shoulder arthroplasty has not been studied to date. The purpose of this study was to determine the effects of BMI on the preoperative and postoperative shoulder range of motion and function in anatomic (aTSA) and reverse total shoulder arthroplasty (rTSA), and specifically how IR affects patient ability to perform IR-related activities of daily living (ADLs). ⋯ Increasing BMI adversely affects shoulder ROM, particularly IR. IR is correlated with the ability to perform ADLs requiring IR in both aTSA and rTSA patients.

Randomized Controlled Trial Multicenter StudyDexamethasone added to levobupivacaine prolongs the duration of interscalene brachial plexus block and decreases rebound pain after arthroscopic rotator cuff repair.
It has been reported that the addition of dexamethasone to interscalene brachial plexus block (ISBPB) prolongs the duration of the block effect. However, there have been no studies focusing on the effects of dexamethasone on rebound pain after the block effect has worn off. The aim of this study was to investigate the effect on postoperative pain when dexamethasone was added to ISBPB for arthroscopic rotator cuff repair (ARCR). ⋯ In ARCR, the addition of dexamethasone to levobupivacaine not only prolongs the duration of ISBPB but also relieves rebound pain after the block effect wears off.

Multicenter StudyCan low-profile double-plate osteosynthesis for olecranon fractures reduce implant removal? A retrospective multicenter study.
Because of poor soft-tissue coverage at the proximal ulna and prominent posteriorly positioned implants, hardware removal remains the most common reason for revision surgery of olecranon fractures that were operatively treated using plate osteosynthesis. We hypothesized that low-profile double-plate osteosynthesis would reduce the number of soft tissue-related hardware removals compared with single posterior plating whereas the functional results would be comparable. ⋯ Low-profile double-plate osteosynthesis for treating olecranon fractures resulted in good clinical outcomes. However, the rate of hardware removal was not significantly reduced, and the functional results were comparable to those of common single-posterior plate osteosynthesis.
