MIYAZAKI, Alberto Naoki et al. Obstetric paralysis: anterior arthroscopic release of the shoulder and transfer of the latissimus dorsi using a homologous graft. Rev. bras. ortop. [online]. 2016, vol.51, n.3, pp.319-328. ISSN 0102-3616.  http://dx.doi.org/10.1016/j.rboe.2016.04.004.

OBJECTIVE:

Description of a new surgical technique for treating the shoulders of patients with sequelae of obstetric paralysis. Preliminary analysis on the results obtained from this technique.

METHODS:

Five consecutive patients underwent the proposed surgical procedure, consisting of arthroscopic anterior joint release followed by transfer of the latissimus dorsi tendon (elongated and reinforced with a homologous tendon graft) to the posterosuperior portion of the greater tubercle, using a single deltopectoral approach. All the patients were reevaluated after a minimum postoperative period of twelve months. The functional assessment was based on the range of motion and the modified Mallet classification system. Statistical analyses were not possible because of the small sample.

RESULTS:

Overall, passive and active lateral rotations increased, while medial rotation decreased. The other movements (elevation, capacity to place a hand in the mouth and capacity to place a hand behind the neck) had less consistent evolution. The mean modified Mallet score improved by 4.2 points (from 11.4 to 15.6).

CONCLUSION:

The latissimus dorsi tendon can be transferred to the posterosuperior portion of the greater tubercle through a single deltopectoral approach when elongated and reinforced with a homologous tendinous graft.
