> Location: Initially bilateral, now left mid-sternal border

> Description: 3/10 dull ache, intermittently sharp

> Alleviating/Aggravating factors:

– Better with rest

– Worse with palpation, deep breathing, overhead movements

> Other: Denied any direct trauma

> Treatments tried: HEP, Physical Therapy, NSAIDs PHYSICAL EXAM:

> NAD

> Significant for tenderness at the left sternocostal border between ribs 4-6

> Non–tender in the pectoralis

> No pain with AROM

> Pain was reproduced with a resisted pushup and overhead press DIFFERENTIAL DIAGNOSIS:

>

> Tietze Syndrome

>

> Pectoralis tear

> Rib fracture

> Thoracic radiculitis

> Xiphoidalgia

> SC joint dislocation/subluxation

Presumed Costochondritis

> Treatment:

– Activity Modification

– Physical Therapy

– Steroid taper for 1 week then 1 week of : >pain returned quickly when transitioning to NSAIDs

> Follow-Up Visit:

– Planned Ultrasound-Guided Steroid Injection

– Same area of persisting pain ULTRASOUND:

NORMAL STERNOCHONDRAL JOINT

PATIENT’S STERNOCHONDRAL JOINT ULTRASOUND:

STERNUM ULTRASOUND:

Acoustic Shadowing

> Occurs when sound waves encounter a dense structure

Gallstone > Sound reflects back to the probe leaving a shadow behind the object

Sternal fracture secondary to left 6th rib dislocation or subluxation

> No injection

> XR Sternum: “subtle or cortical thickening is suspected in the lower sternum…etiology is indeterminate”

> Referred to General Surgery, rib fracture specialist

> Activity Modification, PT, NSAIDs LITERATURE REVIEW

> Sternal ultrasound:

– Nickson, 2011 – median assessment time is ~ 46 seconds

> Return to sport:

– Few similar case reports:

> return to activity once asymptomatic, ranging from 8-16 weeks > Treated with or anti-inflammatories

– Alent et al in 2018 – “largely depend[s] on the severity of the injury, resolution of symptoms, radio-graphic healing, and resolution of associated injuries” DISCUSSION

> Ultrasound can be a useful diagnostic tool to evaluate for occult fracture

> Athletes can sustain sternal fractures without direct trauma

> Return to sport:

– Limited guidelines for pain persisting beyond 12 weeks

> Reminder: Fracture is a contraindication to OMT

> Osteopathic Considerations:

– Could indirect OMT be helpful ? POLL QUESTION!
