Superior capsular reconstruction remains a controversial procedure, and long-term results still need to be established. Graft thickness seems crucial and fascia lata appears superior to dermal allograft. Using a subacromial spacer by suturing dermal allograft to the subacromial bone "increases graft thickness" and reduces superior humeral head migration but increases subacromial pressures in a static laboratory cadaver model. It remains to be seen whether clinical studies support this concept.
