In the absence of maternal thyroid disease or iodine deficiency, fetal goitre is rare and usually attributable to dyshormonogenesis, for which genetic ascertainment is not always undertaken in the UK. Mechanical complications include tracheal and oesophageal compression with resultant polyhydramnios, malpresentation at delivery and neonatal respiratory distress. We report an Indian kindred in which the proband (first-born son) had congenital hypothyroidism (CH) without obvious neonatal goitre. His mother's second pregnancy was complicated by fetal hypothyroid goitre and polyhydramnios, prompting amniotic fluid drainage and intraamniotic therapy (with liothyronine, T3 and levothyroxine, T4)...

PURPOSE: To determine whether generalized hypermobility and contralateral knee hyperextension affect failure rates and patient-related outcomes after anterior cruciate ligament reconstruction (ACLR). METHODS: A total of 226 consecutive patients presenting with acute ACL tears were prospectively evaluated for generalized hypermobility by a modified Beighton criteria. Minimum 2-year follow-up was achieved for 183 knees (81%). Patients underwent ACLR with either bone-patellar-tendon (BPTB) autograft (n = 46), quadrupled hamstring (HT) autograft (n = 85), or allograft tissue (n = 52)...

The most common causes of low back pain in adolescents are spondylolysis and spondylolisthesis. Mechanical factors combined with rapid growth during adolescence place stress on the spine and can result in a stress fracture. Sports that require athletes to repeatedly place the spine in hyperextension may exacerbate both spondylolysis and spondylolisthesis. Many adolescent athletes with spondylolysis or low-grade spondylolisthesis have minimal symptoms and require no treatment or alteration in activity, including sports activity...

PURPOSE: We report the case of a 13-year-old boy managed for fixed cervical hyperextension due to congenital muscular dystrophy with partial merosin deficiency. He presented a right decompensated thoracic scoliosis (T6-L1 Cobb angle 72°) associated with cervical and lumbar lordosis. The spinal extension was accompanied by major flexion of the hip resulting in the trunk being bent forward. This posture caused daily severe back pain responsible for significant loss of quality of life. This led to the decision to perform surgery...

BACKGROUND: Microlaryngoscopy is the preferred and most widely used technique in phonosurgery for the treatment of benign and early malignant glottic lesions. However, the procedure may be technically difficult or impossible due to alterations of the cervical spine that may not allow hyperextension of the head or may present general anesthesia contraindications. The aim of this study is to evaluate the efficacy and safety of our surgical approach for lesions of the vocal folds in patients who are not suitable for phonosurgery by microlaryngoscopy...

Pena-Shokeir phenotype is a lethal anomaly characterized by neurogenic arthrogryposis, craniofacial anomalies, and pulmonary hypoplasia. This syndrome should be distinguished from trisomy 18 and arthrogryposis multiplex congenita for better counseling and establishing fetal prognosis. We present the case of a pregnant woman diagnosed with a Pena-Shokeir phenotype affected fetus at 24 weeks of gestation. Prenatal ultrasonography and fetal magnetic resonance imaging detected persistent hyperextension of the lumbar spine, micrognathia, absent septum pellucidum, and all characteristic features of Pena-Shokeir phenotype...

There is an increased rate of injuries associated with activities on bouncy castles. The purpose of this article was to describe the case of a 6-year-old boy who sustained a brain infarct as a consequence of a left posterior inferior cerebellar artery dissection due to improper landing in a bouncy castle and who required a suboccipital craniotomy. The second goal was to outline the literature review regarding cervical trauma related to trampoline or bouncy castle accidents in pediatric populations. Based on the described case and reviewed studies, bouncy castle or any other activity resulting in hyperflexion or hyperextension of the neck should be carefully evaluated for cervical spine fractures and vascular injuries...

Retroclival epidural haematoma (REDH) has been reported infrequently. It is a rare entity which is probably underdiagnosed. It is most commonly seen in the paediatric population and is generally associated with high-velocity injuries. We report three cases of paediatric patients diagnosed with REDHs: two of them secondary to high-energy trauma related to a motor-vehicle accident and the other a low-energy trauma after a slip while playing football. All three patients were managed conservatively by cervical immobilisation with favourable outcome...

Posterior branches of the lumbar spinal nerves are the anatomic substrate of pain in the lower back, sacrum and the gluteal area. Such pain may be associated with various pathologies which cause pain in the posterior branches of the lumbar spinal nerves due to entrapment, mechanical irritation or inflammatory reaction and/or degeneration. The posterior branches are of significant functional importance, which is related to the function of the structures they supply, including facet joints, which are the basic biomechanical units of the spine...

REVIEW
Alfonso Vaquero-Picado, E Carlos Rodríguez-Merchán
Isolated posterior cruciate ligament (PCL) tears are much less frequent than anterior cruciate ligament (ACL) tears.Abrupt posterior tibial translation (such as dashboard impact), falls in hyperflexion and direct hyperextension trauma are the most frequent mechanisms of production.The anterolateral bundle represents two-thirds of PCL mass and is reconstructed in single-bundle techniques.The PCL has an intrinsic capability for healing. This is the reason why, nowadays, the majority of isolated PCL tears are managed non-operatively, with rehabilitation and bracing...

Y L Tan, F C Yong
The condition of proximal interphalangeal joint (PIPJ) locking in hyperextension may occur in the athetoid or spastic hand with moderate or severe swan-neck deformity at the 'opening' phase of prehension. The patient's complaints are of complete or incomplete locking that may require passive assistance to initiate PIPJ flexion. Surgical procedures to overcome this include rerouting the lateral band, stabilisation or reconstruction procedure for the volar instability of the PIPJ, etc. Volar stabilisation may be achieved by Flexor digitorum superficialis (FDS) tenodesis procedures or criss-cross tendon graft for volar plate reconstruction...

BACKGROUND: Few studies have examined flexion contracture at the time of primary total knee arthroplasty (TKA) or how flexion contracture changes over time. The purpose of this study was to assess the ideal degree of extension immediately after TKA and to document postoperative changes in extension and clinical outcomes over 5-year follow-up. METHODS: This retrospective cohort study included 215 cases of primary TKA. Radiographic evaluations were performed on sagittal radiographs with the patient in the supine position and the knee in gravity and in passive extension using a stress device...

Classical Ehlers-Danlos syndrome (cEDS) is characterized by marked cutaneous involvement that is defined by many criteria of the Villefranche nosology and the 2017 revision. However, the diagnostic flow-chart that prompts molecular testing is still based on experts' opinion rather than systematic published data. Here we report on 62 molecularly characterized cEDS patients with focus on skin, mucosae, face, and joint hypermobility. The major and minor Villefranche criteria, additional 11 mucocutaneous signs and 15 facial dysmorphic traits were ascertained and feature rates compared by sex and age...
