The Frontal Phocomelia in a 3-Year-Old Girl.

Background: Phocomelia is a congenital limb deformity in which the proximal part of the upper or lower limb does not develop. Occasionally the malformed limb may be located ectopically. Case report: We present a frontal phocomelia in a three-year-old girl with right-hand phocomelia and thoracoschisis. The patient's arm was connected directly from the front of the chest, with a rudimentary thumb and two fingers. The truncated arm was not functional. The acromioclavicular joint was abnormal and ectopic, the limb articulated with the medial side of sternum. The thoracoschisis manifested as eventration of the right liver lobe and right side of chest wall. Conclusion: Ectopic phocomelia can be associated with thoracoschisis, it can be nonfunctional, and can articulate with the sternum.

Surgical phocomelia or phoco-reduction as a method of limb salvage for sarcomas of the upper limb: A suitable alternative to amputation.

BACKGROUND: Reconstruction following resection of sarcomas of the upper extremity with methods described in the prevalent literature may not be possible in few selected cases. We describe surgical phocomelia or phoco-reduction as a method of limb salvage in such cases of extensive sarcomas of the upper limb with its functional and oncological outcomes. METHODS: Evaluation of functional and oncological outcomes was performed for 11 patients who underwent surgical phocomelia or phoco-reduction for extensive sarcomas of the upper limb between 2010 and 2019. RESULTS: The mean follow-up period in the study was 27.8 months. Five patients required a segmental resection including the entire humerus while six patients underwent segmental resection around the elbow with a mean resection length of 21.5 cm. Mean Musculoskeletal Tumor Society 93 score was 22 depicting a good functional outcome. Mean handgrip strength on the operated side was 62% of the contralateral side with preservation of useful hand function. Meantime to humeroulnar union was 6.7 months. Radial nerve palsy and implant failure occurred in one patient each. No patient developed local recurrence while three patients died of metastasis. CONCLUSION: Surgical phocomelia is a prudent alternative to severely incapacitating amputations in situations where other reconstruction methods are not feasible.

Pseudo-Roberts Syndrome: An Entity or Not?

Background: Roberts syndrome is a genetic disorder characterized by tetra-phocomelia with abnormalities of ESCO2. We report a male stillborn with tetra-phocomelia and no ESCO2 mutation. Case report: Pre- and post-natal imaging and autopsy findings included schizencephaly, phocomelia of four limbs, micrognathia, oligodactyly, and cardiopulmonary malformations. Microcephaly on pre-natal imaging was not confirmed by autopsy examination. Karyotype, prenatal chromosome microarray and ESCO2 gene testing were normal. Conclusion: Given the various skeletal anomalies found on autopsy and imaging evaluations, at least phenotypically, our case appeared to conform into Roberts syndrome spectrum. Since the infant did not have the mutation associated with this disorder, this infant could be labeled as the first report of a pseudo-Roberts syndrome because many of his phenotypic anomalies are characteristic of Roberts syndrome in absence of the ESCO2 gene mutation.

Lethal Cenani Lenz syndrome in two consecutive pregnancies: Further extension of phenotype from Maldives.

Cenani Lenz syndrome is a rare autosomal recessive disorder associated with variable degree of limb malformations, dysmorphism, and renal agenesis. It is caused due to pathogenic variants in the LRP4 gene, which plays an important role in limb and renal development. Mutations in the APC gene have also been occasionally associated with CLS. The phenotypic spectrum ranges from mild to very severe perinatal lethal type depending on the type of variant. We report a pathogenic variant, c.2710 del T (p.Trp904GlyfsTer5) in theLRP4 gene, in a fetus with lethal Cenani Lenz syndrome with antenatal presentation of tetraphocomelia and symmetrical involvement of hands and feet.

Roberts syndrome in an Indian patient with humeroradial synostosis, congenital elbow contractures and a novel homozygous splice variant in ESCO2.

Roberts syndrome (also known as Roberts-SC phocomelia syndrome) is an autosomal recessive developmental disorder, characterized by pre- and postnatal growth retardation, limb malformations including bilateral symmetric tetraphocomelia or mesomelia, and craniofacial dysmorphism. Biallelic loss-of-function variants in ESCO2, which codes for establishment of sister chromatid cohesion N-acetyltransferase 2, cause Roberts syndrome. Phenotypic spectrum among patients is broad, challenging clinical diagnosis in mildly affected individuals. Here we report a 3-year-old boy with a mild phenotype of Roberts syndrome with bilateral elbow contractures, humeroradial synostosis, mild lower limb disparity, and facial dysmorphism. Trio whole-exome sequencing identified the novel biallelic splice variant c.1673+1G>A in ESCO2 in the patient. Aberrant ESCO2 pre-mRNA splicing, reduced relative ESCO2 mRNA amount, and characteristic cytogenetic defects, such as premature centromere separation, heterochromatin repulsion, and chromosome breaks, in patient cells strongly supported pathogenicity of the ESCO2 variant affecting one of the highly conserved guanine-thymine dinucleotide of the donor splice site. Our case highlights the difficulty in establishing a clinical diagnosis in individuals with minor clinical features of Roberts syndrome and normal intellectual and social development. However, next-generation sequencing tools allow for molecular diagnosis in cases presenting with mild developmental defects.

Complex Anatomic Abnormalities of the Lower Leg Muscles and Tendons Associated With Phocomelia: A Case Report.

Musculoskeletal anatomy is widely known to have components that stray from the norm in the form of variant muscle and tendon presence, absence, origin, insertion, and bifurcation. Although these variant muscles and tendons might be deemed incidental and insignificant findings by most, they can be important contributors to pathologic physiology or, more importantly, an option for effective treatment. In the present case report, we describe a patient with phocomelia and Müllerian abnormalities secondary to in utero thalidomide exposure. The patient had experienced recurrent bilateral foot pain accompanied by numbness, stiffness, swelling, and longstanding pes planus. These symptoms persisted despite conservative treatment with orthotics, steroids, and nonsteroidal anti-inflammatory drugs. Radiographic imaging showed dysmorphic and degenerative changes of the ankle and foot joints. Further investigation with magnetic resonance imaging revealed complex anatomic abnormalities, including the absence of the posterior tibialis and peroneus brevis, lateralization of the peroneus longus, and the presence of a variant anterior compartment muscle. The variant structure was likely a previously described anterior compartment variant, anterior fibulocalcaneus, and might have been a source of the recurrent pain. Also, the absence of the posterior tibialis might have caused the pes planus in the present patient, considering that posterior tibialis tendon dysfunction is the most common cause of acquired pes planus. Although thalidomide infrequently affects the lower extremities, its effects on growth and development were likely the cause of this rare array of anatomic abnormalities and resulting ankle and foot pathologic features.

Shoulder joint replacement can improve quality of life and outcome in patients with dysmelia: a case series.

BACKGROUND: Arthroplasty is a proven treatment option for glenohumeral osteoarthritis. Common indications include primary or posttraumatic osteoarthritis, avascular necrosis of the humeral head, rotator cuff tear arthropathy and rheumatoid osteoarthritis. Arthroplasty is rarely performed among patients with glenohumeral dysmelia. An overuse of the upper limb in patients with thalidomide-induced phocomelia and people with similar congenital deformities like dysmelia results in premature wear of the shoulder joint. This study aims to evaluate our experience with cases of glenohumeral osteoarthritis caused by dysmelia and treated with arthroplasty. To date, few reports on the outcome of shoulder arthroplasty exist on this particular patient group. CASE PRESENTATION: We included four dysmelic patients (five shoulders) with substantial glenoid dysplasia in a prospective database after approval by the local ethics committee. Once conservative treatment options had been exhausted, the patients were treated with shoulder arthroplasty and assessed clinically and radiographically before and after surgery. The mean patient age at the time of surgery was 50.4 years. The minimum follow-up time was 24 months (24-91 months). All patients experienced a considerable improvement of range of motion (ROM) and a relief of pain. No intra- or postoperative complications appeared. CONCLUSION: Patients with dysmelia have acceptable short and mid-term results with resurfacing hemiarthroplasty. It is an effective although somewhat complicated method to relieve pain and improve movement. Long-term performance of arthroplasty in patients with dysmelia remains to be seen, particularly with regard to the remaining problem of the altered and often deficient glenoid.

Thalidomide-induced teratogenesis: history and mechanisms.

Nearly 60 years ago thalidomide was prescribed to treat morning sickness in pregnant women. What followed was the biggest man-made medical disaster ever, where over 10,000 children were born with a range of severe and debilitating malformations. Despite this, the drug is now used successfully to treat a range of adult conditions, including multiple myeloma and complications of leprosy. Tragically, a new generation of thalidomide damaged children has been identified in Brazil. Yet, how thalidomide caused its devastating effects in the forming embryo remains unclear. However, studies in the past few years have greatly enhanced our understanding of the molecular mechanisms the drug. This review will look at the history of the drug, and the range and type of damage the drug caused, and outline the mechanisms of action the drug uses including recent molecular advances and new findings. Some of the remaining challenges facing thalidomide biologists are also discussed.

Neurocognitive profile of a young adolescent with DK phocomelia/von Voss phocomelia/von Voss Cherstvoy syndrome.

DK phocomelia/von Voss Cherstvoy syndrome is a rare condition characterized by upper limb and urogenital abnormalities and various brain anomalies. Previously reported cases have noted significant developmental delays, although no formal testing of cognitive abilities has been reported. In this paper we describe results from a comprehensive neuropsychological evaluation of a 12-year-old male with DK phocomelia syndrome. Test findings indicated mild impairment in intellectual functioning, with more significant impairment in adaptive skills and academic achievement. The neuropsychological profile converged with neurological findings, showing a distinct pattern of strengths and weaknesses that suggests functional compromise of posterior brain regions with relatively well-preserved functioning of more anterior regions. Specifically, impairments were evident in perceptual reasoning, visual perception, and visuomotor integration, whereas normal or near normal functioning was evident in memory, receptive language, social cognition, attention, and most aspects of executive functioning. To our knowledge this is the first report to describe the neurocognitive profile of an individual with DK phocomelia syndrome.

Encephalocele-radial, cardiac, gastrointestinal, anal/renal anomalies: novel evidence for a new condition?

The association between encephalocele and radial defects is considered uncommon. These features have been occasionally described separately in certain recurrent conditions such as VACTERL association, oculo-auriculo-vertebral spectrum and Edwards syndrome (trisomy 18). DK-phocomelia is a rare syndrome characterized by both findings. However, Froster-Iskenius and Meinecke [1992, Clin Dysmorphol 1: 37-41] and Kunze et al. [1992, Eur J Pediatr 151: 467-468] reported patients presenting similar malformations. We proposed, through the description of an additional case, that these last patients present the same condition and thus represent a new syndrome. The fetus presented a cranial vault deformity associated with an exuberant herniation of brain content, compatible with occipital encephalocele. Other uncommon features were also identified: microtia of the left ear with atresia of the external auditory canal; radial defect with aplasia of left radius and thumb; findings suggestive of a congenital heart defect and esophageal atresia; hypoplastic lungs and adrenals; thoracolumbar scoliosis; atrophic right kidney; and single umbilical artery. Thus, based on our review, we believe that these patients represent a new condition characterized by encephalocele and radial defects associated with multiple malformations. We propose, that the name "Encephalocele-radial, cardiac, gastrointestinal, anal/renal anomalies," as suggested by the London Medical Database, or even the name, "Froster-Iskenius and Meinecke syndrome" should be used to indicate these cases. © 2014 Wiley Periodicals, Inc.

Novel prosthesis with proximity sensor for upper extremity phocomelia.

We herein report on the application of a novel motorized prosthetic hand in a child with upper extremity phocomelia.

Non-syndromic phocomelia: A rare case report signifying prenatal screening.

Phocomelia is a rare congenital condition characterized by severe limb malformation, where the limbs are either partly or completely underdeveloped. Phocomelia can occur as a syndrome or as a limb-specific abnormality. The frequency of phocomelia ranges from 0.6 to 4.2 per 100,000 live births; hence, there are not many reports of this deformity. Genetic inheritance and the use of thalidomide are the two main etiological factors of phocomelia. Several symptoms and visceral abnormalities are associated with this condition. Ultrasonography is crucial for the early detection of phocomelia during the intrauterine stage. Presented here is a case of phocomelia in a 6-year-old boy who was diagnosed after birth, with no maternal history of thalidomide usage or family history of the same condition. This case is unique in that it involves a child born with phocomelia but no additional congenital defects observed in related syndromes. Because of that, we suggest this case may be isolated.

Conservative Approach to Type III Ulnar Club Hand: Case Report.

Ulnar club hand is a rare condition of the upper limbs, for which treatment depends on the degree of morphological and functional impairment, correlating with the radiographic classification of Dobyns, Wood, and Bayne. The aim of the present study is to report a case of a 6-year-old male patient, followed up for type III ulnar club hand (total ulnar dysplasia). Despite the initial difficulty of manipulating objects and performing everyday tasks, conservative physical therapy treatment provided strength gain and development of functional skills for daily life. We conclude that patients with type III deformity can be properly managed with rehabilitation although they require outpatient follow-up until skeletal maturity is reached, as dynamic deformities and new functional limitations may lead to need for corrective surgeries.

Case report: vertebral body tethering for idiopathic scoliosis in a patient with bilateral phocomelia.

PURPOSE: The purpose of this study is to present a case report of a patient with bilateral upper extremity phocomelia with progressive scoliosis, who underwent vertebral body tethering (VBT). METHODS: This is a case report on the use of VBT in a patient with scoliosis and bilateral congenital phocomelia, with 5 year follow-up. RESULTS: A male patient with bilateral phocomelia had early onset scoliosis that progressed to 45° at age 10. Surgical options were discussed, including traditional VBT, posterior spinal fusion, growing rods, magnetically controlled growing rods, and vertical expandible prosthetic titanium ribs. These options would limit the flexibility of the spine. Given these pitfalls, VBT was chosen, as it would address the scoliosis while maintaining trunk flexibility. Preoperatively, he had 45° right main thoracic curve, bending to 22°; he was Risser 0 with open triradiate cartilage. He underwent T6-T11 thoracoscopic VBT, with postoperative correction to 37°. Postoperatively, the patient was able to continue to use his lower extremities for writing, feeding, and personal grooming. He had no postoperative complications. At 3 years, his curve was 21°, and at 5 years was 19°. CONCLUSION: This case describes a novel technique for treating scoliosis in patients with bilateral phocomelia. Other forms of scoliosis surgical treatment limit motion of the spine. Due to this, we present VBT as an option for this unique set of patients for correcting scoliosis, while also preserving trunk flexibility for its role in feeding and self-care.

Bilateral Upper Limb Complete Phocomelia: A Case Report.

Introduction: Phocomelia is an uncommon congenital condition in which the hand or foot are normal or almost normal but the proximal section of the limb - the humerus or femur, radius or tibia, ulna or fibula -_is missing or noticeably hypoplastic. It refers to how the patient's limbs resemble marine creatures' flippers and its prevalence is 0.62 in 100,000 births. Case: We present a 15-min-old male neonate born to a para-four mother who did not remember her LNMP but claimed to be amenorrheic for the past nine months. The mode of delivery was by cesarean section to extract alive neonate weighing 2.01 kg with APGAR scores of 5 and 6 at first and fifth minutes, respectively. The neonate did not cry and was resuscitated for five minutes. He was then transferred to neonatal intensive care unit for further management and investigations. His vital signs were pulse rate 160 beats per minute, respiratory rate 70 breaths per minute, temperature 33.4 degrees centigrade and saturation was 60% off oxygen. On HEENT anterior fontanelle measures 2 cm by 2 cm and has micrognathia and short neck. On the respiratory system, there were intercostal and subcostal retractions, labored breathing and grunting. On the musculoskeletal system there is bilateral upper extremity shortening, the right lower limb was normal in position and structure, the left leg rotated inward (bent in medially) at the knee joint and foot was normal in structure. Conclusion: Phocomelia is a rare congenital anomaly in which the hand or foot are directly attached to the trunk. Ultrasonography should be done as early as possible to identify fetal anomalies in order to plan subsequent management.

Unique Roberts syndrome with bilateral congenital glaucoma: A case report.

BACKGROUND: Congenital glaucoma associated with Roberts syndrome (RS) is an unusual and unique condition. No previous report describes this association. A multidisciplinary approach including molecular studies were conducted to reach the final diagnosis. CASE SUMMARY: We present a rare case of a 1-wk-old male with RS associated with bilateral congenital glaucoma, left ectopic kidney, and left-hand rudimentary digits. A comprehensive approach was applied by which bilateral non-penetrating glaucoma surgery was performed with good control of intraocular pressure for more than 6 mo. Cytogenetic and molecular testing were conducted and revealed normal measurements. CONCLUSION: This report described a case of a male baby with clinical features of RS but with a negative molecular analysis, presenting with left-hand rudimentary digits, bilateral congenital glaucoma, and left ectopic kidney. To the best of our knowledge, this is the first case reported with phocomelia, bilateral congenital glaucoma, and unilateral ectopic kidney.

Re-examining the nomenclature of congenital failure of formation in the upper limb: a historical perspective.

In this study, we studied historical case notes to examine nomenclature of congenital upper limb anomalies and explore the changes in terminologies over time. Original diagnoses were reclassified according to previously published classifications and the most recent Oberg, Manske and Tonkin system. Two hundred and thirty-eight case notes were obtained from the period 1961-1991. Hand plate malformations where the diagnosis was obvious or traumatic defects, were excluded. Eighty-six cases (106 extremities) were finally included where an ambiguous diagnosis, such as 'congenital absence' was initially given. None of the re-classifications matched the original diagnoses except for cleft hand and radial dysplasia (n = 31). Eighteen phocomelia-type limbs were re-classifiable when seen as a continuum of longitudinal deficiency, but not as an intercalary deficit. This study provided further insights into the evolving nature of nomenclature in congenital upper limb anomalies, especially for the condition of phocomelia.Level of evidence: IV.

Aesthetic shoulder reconstruction using hypoplastic tissue in a patient with phocomelia - A case report.

We present a case describing a technique for the surgical management and aesthetico-functional reconstruction of a shoulder in an adult with unilateral upper limb phocomelia (ULP).1⁠ A 25 year old male patient was presented to our clinic with upper left limb non-syndromic phocomelia. His main concerns was an aesthetically unpleasant limb and shoulder shape. Few older publications describe available options for pediatric patients, such as clavicle transposition or limb amputation, but nowadays ULP treatment options focus on prosthetic rehabilitation (PR) and targeted muscle reinnervation (TMR). Our patient refused any prosthesis, and TMR is expensive, requires an experienced rehabilitation team and has limited availability. We aim to describe a non-expensive, simple and effective option for selected adult patients with limited shoulder functionality wishes.2-5 We used the existent hypoplastic limb for shoulder mound reconstruction, providing the patient with a more anatomical shoulder shape. The palmar skin of the hypoplastic hand and three existing fingers were excised. Also, distal phalanges were amputated. Then, the hand was rotated and positioned under the coracoid process, creating a shoulder-like mound. Six months later, there has been a loss of shoulder volume compared to early postoperative weeks, but the patient is satisfied with the results. Nevertheless, we found some limitations to our approach such as long-lasting postoperative pain, sensory symptomatology, and loss of volume of the reconstructed shoulder. Those could be solved with the complete denervation of the limb and a Latissimus Dorsi (LD) transposition flap in a second stage of reconstructive surgery.

Total knee arthroplasty and patelloplasty in a patient with phocomelia caused by thalidomide.

The treatment of osteoarthritis in patients with phocomelia with total knee arthroplasty is challenging due to the unusual anatomy and severe deformities. The authors present a case of phocomelia caused by thalidomide with end-stage osteoarthritis and grossly medialized patella. The patient was treated with a cemented constrained non-hinged prosthesis and patelloplasty. Six months later, the patient had complete relief of pain and was able to walk without walking assistance. To our knowledge, total knee replacement in a patient with phocomelia caused by thalidomide has not been described in literature.

A combined case of amelia and phocomelia in a neonate, at JFK Maternity Center, Liberia.

We report a case of spontaneous rare birth deformity. A case of Amelia and Phocomelia in a neonate. Amelia is a rare congenital disorder, even more so, is the combined amelia and phocomelia in a neonate. True Phocomelia was defined as the total absence of the intermediate segments of the limb. With the hand or foot (normal, almost normal, or malformed), directly attached to the trunk. The common aetiological association with phocomelia is from the use of thalidomide and genetic inheritance, as an autosomal recessive trait, involving chromosome 8. Isolated amelia is not generally considered to be of genetic origin. We present a neonate delivered by a 28-years multipara in Liberia, in West Africa Sub-Region, with amelia involving the two upper limbs, right lower limb and a Phocomelia involving the left lower limb (absence of tibia and fibula and feet with three toes). Africa is the only continent not included in the International Clearinghouse for Birth Defects Surveillance and Research. It is hoped that case reports of congenital limb deformities from Africa, will contribute to the formation of a database for birth defects shortly. Funding: None declared.
