Each generation of total shoulder arthroplasy has improved on the previous. The newest humeral component innovation is shortening the humeral component or eliminating the stem entirely to rely on stemless fixation in the humeral metaphysis. This offers theoretical advantages of preserved bone stock, less stress shielding, eliminating the diaphyseal stress riser, ease of stem removal at revision, and humeral head placement independent from the humeral shaft axis. There are a number of short term cohorts that have shown low complication rates and outcomes similar to previous generations of stemmed humeral components. Longer term and better designed studies are needed in order for short stems and stemless components to become the standard of care.

The analysis of this CDVC model suggests six best practices that are essential to successfully scaling up clubfoot treatment programs and ensuring excellent clinical outcomes: (1) diagnosing clubfoot early; (2) organizing high-volume Ponseti casting centers; (3) using nonphysician health workers; (4) engaging families in care; (5) addressing barriers to access; (6) providing follow-up in the patient's community. These practices must be adapted to each context. Applying them will optimize outcomes when designing public health programs that deliver clubfoot care in LMICs.

In conclusion, the MJ approach allows similar access to landmarks important for reduction and fixation while exposing only 20% of the surface area typically visualized with the CJ approach.
