Terminal osseous overgrowth is a common complication after trans-diaphyseal amputation in children, leading to pain, soft tissue problems, and recurrent surgical procedures. We report three different cases with post-amputation issues of osseous overgrowth, ulceration, and deformity over the amputation site. The first case involves a 9-year-old boy with a right leg congenital amputation secondary to amniotic band syndrome. The right below-knee stump later experienced recurrent episodes of osseous overgrowth, leading to ulceration. After the prominent tibia was resected and capped with the ipsilateral proximal fibula, a positive outcome was achieved with no more recurrent overgrowth over the right leg stump. The second case involves a 9-year-old girl born with an amniotic constriction band over both legs. Her left leg remained functional after a circumferential Z-plasty, but the right leg was a congenital below-knee amputation. Multiple refashioning surgeries were performed on the right leg due to osseous overgrowth but the patient continued to experience recurrent overgrowth causing pain and difficulty fitting into a prosthesis. We performed osteocartilaginous transfer of the proximal part of the ipsilateral fibula to the right tibial end, successfully preventing the overgrowth of the tibia without any complications. The third case involves an 11-year-old boy with a history of meningococcal septicemia who underwent a right below-knee amputation and left ankle disarticulation due to complications of septic emboli. He experienced a prominent right distal tibia stump, which later developed into valgus deformity as a result of the previous insult to the proximal tibial growth plate. We performed a corrective osteotomy over the proximal right tibia and capped the entire tibia with the ipsilateral fibula as an intramedullary splint for the osteotomy site. Post-operatively, we achieved satisfactory deformity correction and successfully halted the recurrent overgrowth over the right tibia stump. The method of ipsilateral fibula capping is safe and effective in managing the osseous overgrowth complications in trans-diaphyseal amputations among children. Therefore, it is a reasonable option during primary below-knee amputations in children compared to multiple refashioning surgeries.

Review
Amniotic band syndrome (ABS) and clubfoot are distinct congenital musculoskeletal conditions that can occasionally co-occur, creating unique challenges in their management. This paper summarizes the comprehensive discussion on the management of amniotic band syndrome (ABS) and clubfoot, emphasizing the critical role of the Ponseti method and the challenges faced in treatment, thereby providing a basis for further research and improved patient care.

A biodegradable hybrid polymer patch was invented at the University of Cincinnati to cover gaps on the skin over the spinal column of a growing fetus, characterized by the medical condition spina bifida. The inserted patch faces amniotic fluid (AF) on one side and cerebrospinal fluid on the other side. The goal is to provide a profile of the roughness of a patch over time at 0, 4, 8, 12, and 16 weeks with a 95% confidence band. The patch is soaked in a test tube filled with either amniotic fluid (AF) or phosphate-buffered saline (PBS) in the lab. If roughness is measured at any time point for a patch, the patch is destroyed. Thus, it is impossible to measure roughness at all weeks of interest for any patch. It is important to assess the roughness of a patch because the rougher the patch is, the faster the skin grows under the patch. We use a model-based approach with Monte Carlo simulations to estimate the profile over time with a 95% confidence band. The roughness profiles are similar with both liquids. The profile can be used as a template for future experiments on the composition of patches.

Arthroscopic Transphyseal ACL Reconstruction With Lateral Extraarticular Tenodesis With Unusual Arthroscopic Meniscal Findings in a Case of an Adolescent Girl Previously Diagnosed With Amniotic Band Syndrome.
Amniotic band syndrome (ABS) constriction rings in the lower limb are common. Despite this, there is insufficient literature on anatomical abnormalities in the knee joints of children with ABS. There is an increasing incidence of paediatric anterior cruciate ligament (ACL) injuries recently. ACL reconstruction in this population has an extra dilemma of sparing the physis to prevent growth disturbances. Treating both these conditions simultaneously is a challenge that is rarely encountered. In our literature review, we found no case such as this. As such a case is being described for the first time, we also found certain meniscal anatomical variations on diagnostic arthroscopy. A 12-year-old adolescent Indian girl presented with an ACL tear in her left leg after a school sports injury. She had a known case of ABS constriction bands in both her lower limbs. Her distal femoral and proximal femoral physis was fused on radiographs, so we went ahead with a transphyseal ACL soft-tissue graft reconstruction. On the diagnostic round, we found an anatomical variation of the menisci, which was previously not described since arthroscopy of the knee in an adolescent kid with ABS has not been published in the literature as of yet. These kinds of clinical presentations can become common in the future as more and more kids with ABS take part in recreational sports. In such a scenario, having knowledge about common anatomical variations in the knee of such syndromic patients is essential. While performing ACL reconstructions in this population, we have to be aware of the risk of growth deformities along with vascular and neurological complications, which are added risks with constriction bands around the lower limb.

BACKGROUND
4q21 microdeletion syndrome is an emergent non-recurrent genomic disorder characterized by facial dysmorphy, progressive growth retardation, severe intellectual deficit, and absent or severely delayed speech. Deletions occur in clusters along 4q interstitial or terminal regions. 4q chromosomal aberrations are variable in type, size, and breakpoint. Genotype-phenotype correlation is a challenging task. The recurrent antenatal feature associated a posteriori with this syndrome is intrauterine growth retardation. There are very few precise antenatal descriptions of this syndrome.
METHODS
We report here the first antenatal history of one of the largest deletion of this region.
RESULTS
Our case harbored a 16.9 Mb deletion encompassing 135 protein coding genes including 20 OMIM morbid genes involved in neurological and cognitive abilities. Those breakpoints overlap two clusters of described microdeletion syndromes of cytogenetic band 4q13 and 4q21.
CONCLUSION
From the end of the second trimester, set of call signs associated with this syndrome can be completed by: excess of amniotic fluid, mild growth retardation, short long bones, bony anomalies of the extremities, and bulging cheeks. So, emphasis should be placed on the examination of the extremities, and the face during the routine targeted prenatal ultrasound.

INTRODUCTION
Amniotic band syndrome is a fetal entrapment in strands of amniotic tissue. This condition causes multiple deformities ranging from simple constricting bands to lymphedema, autoamputation, syndactyly and other congenital anomalies. Reconstructive surgery is the main treatment for ABS.
PRESENTATION OF CASE
A 4-year-old male presented with multiple constricting bands affecting both hands in addition to an incomplete syndactyly between the third and fourth left digits. A two-staged operation was performed to repair the deformities with 6 months interval. Series of Z-plasties were used to release the constricting bands and the syndactyly was separated by a web zigzag incision approach and full-thickness skin grafting.
DISCUSSION
Management of ABS must be individualized. The urgency of the surgical release depends on the depth of the constricting bands and their influence on circulation and lymphatic drainage. Superficial bands can be released electively for cosmetic appearance while deep bands should be released as soon as possible. The separation of syndactyly should be done at the first year of life to maintain the digits functionality and parallel growth.
CONCLUSION
This paper emphasizes the importance of early repair of constricting bands associated with syndactyly to avoid the consequences of the delay on digital growth.

This is a case of a fetus affected by an amniotic band detected at 20 weeks of gestation. A presumptive diagnosis was made based on the ultrasound features. The ultrasound showed an abnormally developed right lower limb and no other associated fetal abnormalities. The unilaterality of the defect decreases the chances of genetic abnormality or an early vascular insult. The postnatal examination of the newborn concluded that the prenatal diagnosis was right.
