Summary
Revision surgery for failed shoulder surface replacement hemiarthroplasty (SRH) is challenging. Glenoid erosion is the main failure cause, but outcomes improve with revision to anatomic total shoulder arthroplasty (TSA).
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Musculoskeletal research
Background:
- Shoulder surface replacement hemiarthroplasty (SRH) is a treatment option for shoulder joint issues.
- Failures of SRH can necessitate complex revision procedures.
- Understanding SRH failure modes is crucial for improving surgical outcomes.
Purpose of the Study:
- To identify the primary reasons for shoulder surface replacement hemiarthroplasty (SRH) failure.
- To assess the functional outcomes following revision surgery for failed SRHs.
Main Methods:
- A cohort of 25 patients (26 shoulders) with failed SRHs underwent revision surgery.
- The average time from initial SRH to revision was 3.6 years.
- Functional outcomes were evaluated using the adjusted Constant-Murley score at a mean follow-up of 5.2 years.
Main Results:
- Glenoid erosion (42%) and rotator cuff failure (31%) were the most frequent causes of SRH failure.
- The median adjusted Constant-Murley score at follow-up was 51.6.
- Patients revised to anatomic total shoulder arthroplasty (TSA) showed significantly better outcomes (median score 85) compared to other revision types (median score 36.3).
Conclusions:
- Revision surgery for failed SRH presents technical challenges and variable results.
- Glenoid erosion is the predominant failure mode.
- Revising failed SRH to an anatomic TSA leads to superior functional outcomes.

Muscles of the Shoulder
9.3K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Hypothesis: Accept or Fail to Reject?
29.6K
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Continuous Renal Replacement Therapy
1.1K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Surface Tension and Surface Energy
3.3K
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Wood Surfacing
365
Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
232
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...
