The coronal unicondylar fracture of the distal femur (AO 33-B3) is a rare intraarticular injury within the weight bearing area of the knee, initially described by Albert Hoffa in 1904. We report an unusual combination of a Hoffa fracture with lateral patellar dislocation in a young adult. Our patient sustained the injury by a sudden twist of his leg during sports. He presented clinically with knee swelling, dislocation of the patella, and localized tenderness; unable to bare weight. After plane radiograph confirmed the injury, manual reduction of the patella was done by hyperextension of the knee and medialward pressure...

Patients with Ankylosing Spondylitis (AS) are four times more likely to sustain spinal fractures. Due to the associated risk of neurological complications treatment is complex. We present the case of a 56-year-old Caucasian gentleman with AS who sustained a fracture of T2 vertebra following a traumatic hyperextension injury. He declined surgery in fear of complications and started treatment with subcutaneous Teriparatide at a dose of 20 mg daily for six months. There was complete healing of the vertebral fracture at 6 months without any complications...

REVIEW
Paige M Fox, James Chang
Swan neck and boutonniere deformities of the proximal interphalangeal (PIP) joint are challenging to treat. In a swan neck deformity, the PIP joint is hyperextended with flexion at the distal interphalangeal (DIP) joint. In a boutonniere deformity, there is flexion the PIP joint with hyperextension of the DIP joint. When the deformities are flexible, treatment begins with splinting. However, when the deformity is fixed, serial casting or surgery is often necessary to restore joint motion before surgical correction...

BACKGROUND: Clinical checklists available have been developed to assess the risk of a positive Fragile X syndrome but they include relatively small sample sizes. Therefore, we carried out a meta-analysis that included statistical pooling of study results to obtain accurate figures on the prevalence of clinical predictors of Fragile X syndrome among patients with intellectual disability, thereby helping health professionals to improve their referrals for Fragile X testing. METHODS: All published studies consisting of cytogenetic and/or molecular screening for fragile X syndrome among patients with intellectual disability, were eligible for the meta-analysis...

Fractures of the C1 vertebrae (atlas) are commonly the result of falls and other trauma, which cause hyperextension, or axial compression of the cervical spine. Although historically thought as a benign injury with lower neurological risks, current data suggests that this may not hold true for geriatric patients (aged 65 y and older) who may be predisposed to these fractures even after lower-energy trauma such as ground-level falls. Advancements in orthopedic trauma care has increased our diagnostic abilities to identify and manage patients with C1 fractures and other upper cervical spine trauma...

AEBP1 encodes the aortic carboxypeptidase-like protein (ACLP) that associates with collagens in the extracellular matrix (ECM) and has several roles in development, tissue repair, and fibrosis. ACLP is expressed in bone, the vasculature, and dermal tissues and is involved in fibroblast proliferation and mesenchymal stem cell differentiation into collagen-producing cells. Aebp1-/- mice have abnormal, delayed wound repair correlating with defects in fibroblast proliferation. In this study, we describe four individuals from three unrelated families that presented with a unique constellation of clinical findings including joint laxity, redundant and hyperextensible skin, poor wound healing with abnormal scarring, osteoporosis, and other features reminiscent of Ehlers-Danlos syndrome (EDS)...

Introduction: Surfer's myelopathy (SM) is a rare cause on non-traumatic acute myelopathy. This has classically been described in novice surfers however has been reported in other scenarios. Case presentation: We present a case of non-traumatic paraparesis associated with prolonged cervical hyperextension during swimming with imaging characteristics consistent with an unusual variation of SM in a swimmer. Discussion: SM and its variants should be considered in the differential diagnosis of any patient presenting with an anterior spinal cord syndrome with a history of either sustained or repeated spinal hyperextension...

BACKGROUND: Hyperextension of the femoral component and excessive slope of the tibial component may delay the cam-post engagement in semi-constrained revision total knee arthroplasty (TKA). Further, it may compromise the posterior condylar offset (PCO). No prior study has determined whether a short 50-mm stem, or longer stems (100mm and 150mm) lead to less hyperextension of the femoral component or excessive slope and its influence on the posterior condylar offset. METHODS: Flexion/extension of the femoral component with respect to the sagittal femoral anatomic axis of the distal diaphysis (SFAA) and the tibial slope were measured from rotationally controlled lateral X-rays of 126 consecutive patients with a one- or two-stage revision TKA...

Typical lesions of the carpal ligaments are mostly found after a fall on the wrist in hyperextension or as complex injuries after severe trauma, e. g. after a fall from a significant height, motorcycle accident or as accompanying lesions in multiple trauma. The typical mechanisms, patterns and diagnostic algorithms are well known for the common ligamentous injuries (e.g. scapholunate, lunotriquetral and perilunate); therefore, consistent diagnostic procedures and adequate therapy are increasingly performed after such lesions, e...

Ehlers-Danlos syndrome classical type (cEDS) is a connective tissue disorder characterized by skin hyperextensibility, atrophic scarring, and joint hypermobility. The condition typically results from mutations in COL5A1 or COL5A2 leading to the functional haploinsufficiency. Here, we report of a 24-year-old male with mild intellectual disability, dysmorphic features, and a phenotype consistent with cEDS. A copy number variant-calling algorithm from panel sequencing data identified the deletions exons 2-11 and duplications of exons 12-67 within COL5A1...

Decreased active and passive range of motion (ROM) accompanied by pain in the shoulder is a common presentation for patients with frozen shoulder, and it can be difficult to restore normal function. Through the fascial distortion model, physicians can apply a manual technique to rapidly and effectively increase ROM and decrease pain. A 28-year-old man presented 18 months after sustaining a shoulder hyperextension injury. On active and passive ROM examination, he had approximately 90° of shoulder abduction and moderately reduced internal rotation associated with 8/10 pain...

The PITX2 (paired-like homeodomain 2) gene encodes a bicoid-like homeodomain transcription factor linked with several human disorders. The main associated congenital phenotype is Axenfeld-Rieger syndrome, type 1 (ARS), an autosomal dominant condition characterized by variable defects in the anterior segment of the eye, an increased risk of glaucoma, craniofacial dysmorphism and dental and umbilical anomalies; in addition to this, one report implicated PITX2 in ring dermoid of the cornea and a few others described cardiac phenotypes...

A 22-year-old woman presented with 12 years of progressive constipation; she had increased joint flexibility, hyperextensible skin, and excessive perineal descent on examination. Radiological studies confirmed evidence of rectal evacuation disorder due to descending perineum syndrome, enterocele, and rectocele. In a wide genetic screen (∼611,000 single nucleotide polymorphisms), 4 variations were identified in COL1A1 gene ([rs72656352, Chr17: 50,185,535-50,185,539, deletion], [rs72654794, Chr17: 50,188,575, deletion], [rs72667023, Chr17: 50,198,170, deletion], [rs67828806, Chr17: 50,198,177 G→C])...

REVIEW
Francesca Cortini, Chiara Villa
The Ehlers-Danlos syndromes (EDS) comprise a clinically and genetically heterogeneous group of heritable connective tissue disorders (HCTDs), characterised by joint hypermobility, hyperextensibility of the skin and tissue fragility that can induce symptoms from multiple organ systems. The latest EDS nosology distinguished thirteen subtypes with an overlap of phenotypic features, making the clinical diagnosis rather difficult and highlighting the importance of molecular diagnostic confirmation. Although the nervous system is not considered a primary target of the underlying molecular defect, recently, increasing attention has been focused on neurological manifestations of EDS...

In patients with pre-existent cervical spinal canal stenosis, minimal trauma, leading to neck hyperextension, can cause a significant increase of spinal cord compression. However, spinal cord injury is generally associated with major trauma and is usually not expected in patients with minor trauma. The resulting symptoms are diverse, making it even more difficult to diagnose. To illustrate the variety in symptoms at presentation, we describe two male patients aged 66 and 69. Rapid diagnosis is important as acute neurosurgical intervention may be indicated...

REVIEW
Philip Rosinsky, Oren Sarig, Yehuda David, Amir Oron
Mallet finger is a common injury involving the extensor mechanism of the finger. It presents as an inability to extend the distal phalanx of the digit. In the right clinical setting, a thorough examination should be performed and supplemented by adequate radiographs. The mechanism of injury is usually a direct blow to an extended finger causing hyperflexion or hyperextension of the distal phalanx. Common occurrences are in young adults during sporting activities or in minor falls or trauma in osteoporotic individuals...

Patients' with a hemiplegic gait and difficulties with activities of daily living may improve through intensive training of their paretic lower limbs. This study examined the possibility of improving their gait by immobilizing the non-paretic knee joint in extension and promoting weight shift toward the paretic side. Single-case ABABA studies were conducted, involving three patients with hemiplegia. The patients walked with their non-paretic knee joints immobilized in extension using a dial-lock knee orthosis during the intervention (B1 and B2) periods...
