[Shoulder dislocation in the newborn. Report of 12 cases and review of the literature]

Congenital anterior shoulder dislocation in a newborn treated with closed reduction

Case: This rare case presents an isolated congenital shoulder dislocation in a twin delivery, without traumatic delivery. Delivered by emergent cesarean section at 33 weeks gestation, the infant presented with a lateral shoulder crease with x-rays showing anterior and inferior dislocation. Treatment included prompt reduction and stabilization, with follow-up ultrasound demonstrating a physeal injury.

Conclusions: This case report presents the only published congenital shoulder dislocation in an infant after an atraumatic twin cesarean delivery. Prompt reduction, stabilization, and ultrasound imaging to assess for physeal injury is our recommended management for this scenario.

The Surgical Strategy to Correct the Rotational Imbalance of the Glenohumeral Joint after Brachial Plexus Birth Injury

In upper brachial plexus birth injury, rotational balance of the glenohumeral joint is frequently affected and contracture in medial rotation of the arm develops, due to a severe palsy or insufficient recovery of the lateral rotators. Some of these children present with a severe glenohumeral joint contracture in the first months, although regular physiotherapy has been provided, a condition associated with a posteriorly subdislocated or dislocated humeral head. These conditions should be screened early by a pediatrician or specialized physiotherapist. Both aspects of muscular weakness affecting the lateral rotators and the initial or progressive glenohumeral deformity and/or subdislocation must be identified and treated accordingly, focusing on the reestablishment of joint congruence and strengthening of the lateral rotators to improve rotational balance, thus working against joint dysplasia and loss of motor function of the shoulder in a growing child. Our treatment strategy adapted over the last 20 years to results from retrospective studies, including biomechanical aspects on muscular imbalance and tendon transfers. With this review, we confront our actual concept to recent literature.

A Rare Complication of Tuberculous Meningitis Pediatric Anterior Glenohumeral Instability

Dislocation and instability of the shoulder joint are rare occurrences in childhood. Traumatic, infectious, congenital, and neuromuscular causes of pediatric recurrent shoulder dislocations are reported before. Central nervous system infection in infancy may be a reason for shoulder instability during childhood. This situation, which causes a disability for children, can be treated successfully with arthroscopic stabilization of the shoulder and postoperative effective rehabilitation protocols. Tuberculous meningitis may be a reason for neuromuscular shoulder instability. We describe a 12-year-old child with a recurrent anterior instability of the shoulder, which developed after tuberculous meningitis at 18 months of age. We applied arthroscopic treatment and stabilized the joint.

Sequelae of an undiagnosed unilateral congenital fixed anterior shoulder dislocation in a 40-year-old female

Congenital shoulder dislocation is a rare condition. A review of the literature showed that 0.018-0.07% of newborns suffer from shoulder dislocations. There have been only few reports about this entity, clinic and radiologic features, treatment, and etiology of this condition remains unclear. We report a case of undiagnosed unilateral congenital fixed anterior shoulder dislocation in a 40-year-old female, which affected the day quality of life. Pediatrists and orthopaedic surgeons should know this rare condition and the importance of a proper diagnosis in the early childhood when an appropriate treatment could be performed.

True congenital dislocation of shoulder: A case report and review of the literature

The dislocation of a shoulder joint in infancy is extremely rare and is usually the result of traumatic birth injuries, a sequel to brachial plexus injury, or a true congenital dislocation of shoulder. With more advanced obstetric care, the incidence of first two types has drastically decreased. We report a case of true congenital dislocation of shoulder, second of its kind, in a child who was delivered by cesarean section thereby negating any influence of trauma. We report the case because of its rarity, and review the available literature on this topic. We also discuss the management options when encountered with such a rare case scenario.

Shoulder dislocation in a very-low-birth-weight infant: case report and review of the literature

Shoulder dislocation in a preterm infant is very rare. We report a case of a preterm infant, with gestational age of 25 2/7 weeks and birth weight of 910 g, with anterior shoulder dislocation after breech delivery. The infant was successfully treated with closed reduction. In general, long-term outcome of shoulder dislocation in these infants is good. However, prompt recognition and treatment of the dislocated shoulder are essential to maintain normal shoulder girdle function and to prevent functional disability.
