Advantages: | |
∙ More-anatomic dynamic reproduction of SSP function ∙ Re-normalized GH kinematics (centralized humeral head over the glenoid) ∙ Avoidance of mechanical block of the tendon reconstruct ∙ Effective reproduction of anatomic RC footprint ∙ Preserved scapular kinematics ∙ Versatile indications ∙ Technical simplicity, familiarity, safety & reproducibility ∙ Interposed hamstring sheet is to minimize sub-periosteal trapezius dissection, tension over the reconstruct and displacement of related neuro-vasculatures ∙ No violation of AC joint ∙ Feasibility of arthroscopic-assisted modality of the technique ∙ Feasible concurrent GH reconstructive procedures (e.g. latissimus dorsi transfer, ex-SALT) ∙ Accelerated postoperative rehabilitation ∙ Relatively-easy revision | |
Limitations: | |
∙ Possible seroma formation ∙ Relatively higher risk of post-operative infection ∙ Technical irreproducibility in trapezius muscle paralysis ∙ Multiple re-attachment interfaces ∙ No biomechanical validation ∙ No related electrophysiological evidence ∙ No long-term cohort clinical studies ∙ Unclear biomechanical consequences on nearby cervical spine |
