Obstetric brachial plexus palsy [OBBP] can affect the function of the upper extremity. Most of the injuries are limited to the upper spinal nerves and heals spontaneously. However, some of them will have incomplete recovery after OBBP often results in weakness of the external rotators [teres minor and infraspinatus] muscles compared to the internal rotators [teres major, pectoralis major, latissimus dorsi] muscles. The predominance of the internal rotators and adductor muscles over external rotators leads to an internal rotation contracture. The development of internal rotational deformity may progress to increased glenoid retroversion and posterior humeral head subluxation. If the surgeon does not repair internal rotation deformity, the humeral head is forced into a posterior position causing a complete posterior dislocation. Many procedures are performed to treat these deformities: In the young child, improving the remodeling of the glenohumeral joint, capsulectomy, and subscapular release are introduced. Tendon transfers of the shoulder have good results for motion but fail to restore the glenohumeral joint. The failure of improving joint alignment may represent the loss in clinical improvement over time. In older children, a humeral osteotomy can be an alternative to realign the limb into external rotation, improve appearance, and enhance eating, washing hair, and scratching the back of the neck. We will discuss all the techniques along with their advantages and disadvantages.

Shoulder Reconstruction

We assessed the outcomes in 24 of 25 children (mean age 3 years) who had soft-tissue shoulder reconstruction procedures for obstetric brachial plexus injuries. All had latissimus dorsi and teres major transfers to strengthen external rotation combined with subscapularis lengthening, reduction of posterior dislocation or subluxation, and humeral osteotomy, if necessary. At a mean follow-up of 3.8 years, the mean Mallet score improved from 12.3 preoperatively to 17.4 postoperatively, active external rotation improved from 21° to 32°, and passive external rotation improved from 26° to 67°. The shoulder remained in joint in all patients. Active internal rotation deteriorated in nine shoulders, two requiring secondary internal rotation osteotomy. Combined soft tissue rebalancing and bony procedures gives reliable shoulder function improvement. Care is required regarding the effect on internal rotation.

Rotation Osteotomy

Shoulder internal rotation contracture is the most common deformity affecting the shoulder in patients with Obstetric Brachial Plexus Palsy. With progression of the deformity, the glenohumeral joint starts to subluxate and then dislocates. This is accompanied with bony changes of both the humerus and the glenoid. Two opposite direction humeral osteotomies have been proposed for this condition (internal rotation osteotomy (IRO) and external rotation osteotomy (ERO)). This fact of different direction osteotomies has not adequately been explained in the literature. Most orthopedic surgeons may not be able to fully differentiate between these two osteotomies regarding the indications, outcomes and effects on the joint. This review explains these differences in details.

Abstract The purpose of this study is to evaluate the glenohumeral contact area, center of glenohumeral contact area, and center of humeral head during simulated pitching motion in collegiate baseball pitchers using four-dimensional computed tomography (4D CT). We obtained 4D CT data from the dominant and non-dominant shoulders of eight collegiate baseball pitchers during the cocking motion. CT image data of each joint were reconstructed using a 3D reconstruction software package. The glenohumeral contact area, center of glenohumeral contact area, center of humeral head, and oblateness of humeral head were calculated from 3D bone models using customized software. The center of glenohumeral contact area translated significantly from anterior to posterior during maximum external rotation to maximum internal rotation. The center of humeral head translated from posterior to anterior during maximum external rotation to maximum internal rotation. There was a high negative correlation between anterior translation of the center of glenohumeral contact area and center of humeral head, and a positive correlation between the translation and the oblateness. 4D CT analyses demonstrated that the center of humeral head translated in the opposite direction to that of the center of glenohumeral contact area during external rotation to internal rotation in abduction in the dominant and non-dominant shoulders. This diametric translation can be explained by the oblateness of the humeral head. 4D CT scanning and the software for bone surface modeling of the glenohumeral joint enabled quantitative assessment of glenohumeral micromotion and identified humeral head oblateness as the cause of diametric change.

Shoulder External Rotation

The Mallet grading system is a commonly used functional scoring system to assess shoulder abduction/external rotation deficits in children with obstetric brachial plexus palsy. One feature of the Mallet score is that each grade is translated into certain degrees of deficiencies in both shoulder abduction and external rotation. The aim of the current study is to investigate the percentage of children in which the Mallet score could not be applied because of a discrepancy between the deficiency of shoulder abduction and shoulder external rotation. The study group included 50 consecutive unoperated older children (over 5 years of age) with Erb’s palsy and deficits in shoulder movements. The Mallet score could be applied in 40 cases (80%). In the remaining 10 cases (20%), the Mallet score could not be applied either because shoulder abduction had a better grade than the grade of shoulder external rotation (n=7) or vice versa (n=3). It was concluded that documenting the deficits in shoulder abduction and external rotation are best done separately and this can be accomplished by using other grading systems.

Introduction. Shoulder internal rotation contracture is the most common deformity affecting the shoulder in patients with obstetric brachial plexus palsy because of the subsequent imbalance of the musculature and the abnormal deforming forces that cause dysplasia of the glenohumeral joint. Aim. To assess the effects of tendon transfers in children with shoulder internal rotation deformity due to obstetric brachial plexus palsy. Materials and methods. From 2015 to 2017, we examined and treated 15 patients with shoulder internal rotation deformity caused by obstetric brachial plexus palsy. The children ranged in age from 4 to 17 years. We used clinical and radiographic examination methods, including magnetic resonance imaging, electromyography, and electroneuromyography, of the upper limbs. Results. According to the level of plexus brachialis injury, the patients were divided into 3 groups: level С5–С6 (9 patients), level C5–C7 (5 children), level С5–Th1 (1 patient). All children had secondary shoulder deformities: glenohumeral dysplasia type II, 6 (40%); type III, 5 (34%); type IV, 1 (6%); and type V, 3 (20%). The Mallet score was used for estimation of upper limb function. Surgical treatment was performed in 15 children. After treatment, all patients showed improvement in activities of daily living. Conclusion. Tendon transfers in patients with shoulder internal rotation deformities due to obstetric brachial plexus palsy improved upper limb function and provided satisfactory cosmetic treatment results without of remodeling of the glenohumeral joint.

This study aimed to evaluate the potential relationship between body composition (percentage of fat mass (FM %), fat mass and lean mass), muscle function (e.g., muscles; deltoid side and front, pectoralis major and teres major) and the propulsive force of the arm (PFA). Sixteen competitive surfers (29.1 ± 7.3 years; 1.72 ± 0.06 m; 74.2 ± 1.4 kg) were assessed for height, body mass, body composition (dual-energy-DXA), muscle function and PFA. Pearson correlation analyses were used to verify the relationship between all variables. An inverse correlations were found between PFA and isokinetic parameters to 60o/s: external rotation (peak torque: r = -0.71; p = 0.014; total work: r = -0.75; p = 0.007; power: r = -0.72; p = 0.011) and internal rotation (peak torque: r = -0.61; p = 0.045; total work: r = -0.73; p = 0.010; power: r = -0.61; p = 0.045) and 300o/s: external rotation (peak torque: r = -0.79; p = 0.003; total work: r = -0.84; p<0,001; power: r = -0.81; p = 0.002) and internal rotation (peak torque: r = -0.69; p = 0.017; total work: r = -0.72; p = 0.011; power: r = -0.69; p = 0.017). There was no significant correlation between body composition components and PFA (p>0.05). Although correlations do not imply cause and effect, PFA is not correlated with body composition in surfers and these relationships are inversely related to the parameters of muscle function.
