obstetric brachial plexus palsy
Incidence : 0.1-0.4%
Incomplete Recovery : 49%-66%
Indication of Microsurgical Neural Reconstruction : dysfunction of elbow flexion at the age of 3 month
Sequelae of shoulder
C5 , C6 injuries ( Erb’s palsy ) C5 , C6 , +C7 injuries ( Erb’s palsy+C7 )
loss of active ER
loss of shoulder elevation
Loss of active shoulder elevation and ER can lead to simple tasks, such as shaking hand, combing, brushing teeth, becoming impossible due to the inability of controlling the spatial positioning of the arm .

Shoulder Reconstruction
Background
We modified Teres Major & Latissimus Dorsi transfer, from original L’Episcopo’s and
Nath’s procedures, to reconstruct shoulder function.
The deltopectoral approach to release contracted subscapularis, pectoralis major and
conjoint tendon of the teres major and latissimus dorsi
The posterior approach to reinsert the conjoint tendon to the belly of the teres minor
Background
To retrospectively analyze the outcomes and related factors of modified teres major and
latissimus dorsi transfer in the treatment of obstetric brachial plexus palsy (OBPP)
shoulder sequelae.
Materials and Methods
General Conditions
From 2008 to 2011
six patients with OBPPs, aged from 16 months of age to 16 years of age.
2 males and 4 females
Left: 3, Right: 3
No primary microsurgical reconstruction
Diagnosis: C5+C6 (n=5)
C5+C6+C7 (n=1)
Materials and Methods
The pre- and postoperative active shoulder abduction and ER were recorded and
evaluated according to Mallet’s classification.
Comparison between the pre- and postoperative was performed by t-test.
Operative methods

Operative methods
Operative methods
The upper extremities were immobilized for 6-8 weeks in the position of
abduction 90 degrees and ER 45 degrees except for two patients in the
position of adduction and internal rotation.
All patients were followed for 3 to 22 months.

Typical Cases
Preoperative: Abduction 90°, ER 0°( Mallet Score 3)
Postoperative: Abduction 160°, ER 90°( Mallet Score 5)
Typical Cases
Preoperative: Abduction 50°, ER 0°( Mallet Score 3)
Postoperative: Abduction 130°, ER 45°( Mallet Score 5)
The position of postoperative Immobilization can influence outcomes of ER
2 patients were immobilized in shoulder adduction and internal rotation

Post- 90 45
Conclusion
Modified teres major & latissimus dorsi transfer can improve shoulder
abduction and ER by increasing stability of the glenohumeral joint.
The postoperative immobilization position can influence the improvement
of shoulder ER.
