Presentation & history
Late-cocking pain had begun to change both pitch shape and recovery between appearances.
What brought him inIn this constructed scenario, a professional right-handed pitcher reports six weeks of deep shoulder pain during late cocking and early acceleration. Rest settles the symptoms, but high-intent throwing reliably brings them back.
What had already been triedHis training staff had reduced workload, adjusted recovery, and begun focused rehabilitation. Daily function remained comfortable; the problem appeared only near game-speed demand.
Imaging findings
The catalog describes a coronal T1 fat-suppressed series showing a labral tear. No source image is displayed here.
Working diagnosis
Symptomatic superior labral tear of the throwing shoulder
The diagnosis is framed as a match between history, examination, imaging, and the very specific demands of high-velocity throwing—not an MRI label in isolation.
- Deep pain at high throwing intensity
- Symptoms in the late-cocking phase
- Preserved day-to-day function
- No frank instability in this scenario
Why consider a biologic procedure?
The decision was not “injection instead of surgery.” It was a measured trial within a wider plan, with surgery still on the table.
Why it fit this constructed case
- Symptoms persisted despite workload change and rehabilitation.
- Strength and stability were preserved.
- The athlete wanted a structured, time-bounded option before operative care.
- Rehabilitation and throwing progression could be closely supervised.
What remained explicit
- Response to an orthobiologic procedure cannot be guaranteed.
- The tear itself may remain visible on imaging.
- Persistent mechanical symptoms or failed progression would prompt reassessment.
- Surgical consultation remained a valid next step.
Terminology: Lipogems is microfragmented adipose tissue. It retains structural and signaling components, including mesenchymal signaling cells; it is not presented here as a promise to regenerate a new labrum.
Ultrasound-guided procedure
The key ideas are sterile processing, real-time visualization, and precise intra-articular placement.
- Plan the targetConfirm the intended glenohumeral target, review anatomy and imaging, and discuss risks, alternatives, uncertainty, and the rehabilitation plan.
- Harvest adipose tissueObtain a small volume of the athlete’s own subcutaneous adipose tissue using sterile technique and local anesthesia.
- Microfragment in a closed systemProcess the tissue with the Lipogems system to create microfragmented adipose tissue while minimizing open handling.
- Guide the needleUse real-time ultrasound to visualize the needle path, avoid nearby structures, and confirm intra-articular positioning.
- Deliver and protectAdminister the individualized treatment volume, apply harvest-site compression, and begin a staged recovery plan. NSAIDs are avoided around the procedure.
Criteria-led recovery
Calendar dates open the door; symptoms, strength, mechanics, and throwing tolerance decide whether to walk through it.
- Protect the procedure
Relative shoulder rest, gentle comfortable motion, and one week of harvest-site compression. Avoid NSAIDs; use the treating physician’s medication plan.
- Restore the base
Progress mobility, scapular control, and rotator-cuff loading under supervision. No high-intent throwing.
- Begin return-to-play progression
If examination and symptoms permit, introduce a monitored throwing progression rather than an immediate return to competition.
- Reassess the signal
Review pain response, strength, mechanics, workload tolerance, and the next throwing step.
- Advance toward full sport
Build intensity and volume in stages. Full sport is considered within this window only if objective and sport-specific criteria are met.
- Decide what comes next
Confirm progression, modify workload, or reconsider the diagnosis and alternatives—including surgical input—if the athlete is not advancing.
This timeline reflects the teaching protocol for the composite case. It is not a prediction of outcome or a substitute for an individualized plan.
Teaching takeaways
- Treat the athlete, not an isolated MRI finding.
- In a thrower, the timing and intensity of symptoms matter.
- Ultrasound guidance supports precise, observable placement.
- Biologics are a decision point, not a guarantee.
- Rehabilitation is part of the procedure—not an afterthought.
- Keep clear checkpoints for reassessment and surgical referral.
Frequently asked questions
Does Lipogems “heal” a labral tear?
No such promise can be made. The clinical aim is to support a better biologic environment and function within a complete rehabilitation plan. Symptoms, performance, and follow-up—not marketing language—guide the assessment.
Why avoid NSAIDs around the procedure?
NSAIDs are avoided under this protocol because their anti-inflammatory effect may work against the intended post-procedure biologic response. Medication decisions should always account for the individual’s health and the treating physician’s instructions.
Why use ultrasound if the tear is seen on MRI?
MRI and ultrasound play different roles. MRI helps characterize intra-articular structure; ultrasound provides real-time visualization of the needle, surrounding anatomy, and injection target during the procedure.
When would surgery move back to the foreground?
Persistent mechanical symptoms, instability, loss of function, inability to progress through rehabilitation, or failure to meet the athlete’s performance needs would all justify reassessment and surgical consultation.
