Accelerated Pec Rupture Rehabilitation Cheat Sheet

October 3rd, 2024

Pectoralis major ruptures in sport are on the rise, so what do you need to know?

Mechanism of Injury 

Horizontal extension (62.5%) is the most common mechanism, followed by hyperflexion-abduction (25%) and finally horizontal adduction (12.5%) as displayed in Fig.1

Patho anatomy

The insertion point of the sternocostal head is the most common rupture site.2

Isolated ruptures to the clavicular are extremely rare, as low as 1% in systematic review.3

Equally, ruptures at the muscle origin, muscle belly, and bony avulsions are also very rare.3        

Surgery or Conservative?

The majority of these are treated surgically.3

In Bodendorfer and colleagues systematic review (n=664), operative treatment was significantly superior to nonoperative treatment in the following measures:2

  • Functional outcome (+23%)
  • Isometric strength (+77%)
  • Isokinetic strength (+29%)
  • Cosmesis satisfaction (+14%)
  • Resting deformity (+99%)

Complication rate for operative treatment was 14% and a re-rupture rate of only 3%.2  

Return to Sport Timelines:

In the literature, the wide range of timelines reflects the limited research regarding return to play:

  • AFL: 11 weeks (8-15 weeks)2
  • Multi-sport: 6.1 months (+- 1.7 months)3
  • NFL: 16 - 21 weeks5,6

Cullan Ball’s recent Sports MAP Masterclass details an accelerated return to play program with the goal of returning at approximately 12 weeks post-op (Table 1). 

Week(s)Objective
0 - 2Rest / protect in sling
Contralateral and lower limb loading
2 - 3Early ROM exercises
Wean from sling
4 - 5Isometrics / isotonics
Running resumes with habitual arm swing
6 - 7ROM restored
Plyometrics introduced
8 - 9Return to modified training
Contact retraining commences
10 - 11Full strength restored
Return to training
12+Return to play

Return to Play Testing

The ASH-Test is recommended to assess an athlete’s ability to contract force quickly through the pectoral / anterior shoulder.

Ben Ashworth in his Sports MAP Masterclass outlined the following goals with the test:

  • In the I-position, aim for peak force >2N/BW and a rate of force development (@ 100ms) of >500N/sec
  • The Y-Position is 85% and T-position is 75% of total strength when compared to the I-position
