Objective: To investigate the clinical efficacy of dynamic cross screw system (FNS) for femoral neck fractures in young and middle-aged patients with posterior medial comminution. Methods: A retrospective cohort study. Clinical data of 197 young and middle-aged patients with femoral neck fractures accompanied by posterior medial comminution treated with closed reduction FNS and internal fixation with anti-rotation cannulated screws in Beijing Luhe Hospital, Beijing Jishuitan Hospital and Beijing Tongren Hospital from October 2019 to October 2021 were analyzed retrospectively...

Spondyloepimetaphyseal dysplasia (SEMD) is characterized by vertebral, epiphyseal, and metaphyseal alterations. Patients become predominantly apparent with disproportionate short stature. The genetic background of SEMD is heterogeneous, with different modes of inheritance (autosomal dominant, autosomal recessive, and X-linked disorders). Amongst the genes in which variants are known to cause SEMD, UFM1-specific protease 2 ( UFSP2 ) encodes a cysteine protease involved in the maturation of Ubiquitin-fold modifier 1 (UFM1)...

INTRODUCTION: X-linked hypophosphatemic rachitis (XLHR) is the most common cause of hereditary rickets that can lead to long bone deformities requiring multiple surgical correction procedures. In addition, high rates of fractures are reported in adult XLHR patients. This study aimed to report a case of femoral neck stress fracture in XLHR patient treated with mechanical axis correction. No previous studies demonstrating a combined valgus correction and cephalomedullary nail fixation were identified in the literature...

This study aimed to evaluate the prevalence of and risk factors for coxa vara deformity in patients with Fibrous Dysplasia/McCune-Albright Syndrome (FD/MAS). This study was conducted at the National Institutes of Health and Leiden University Medical Center. All patients with any subtype of FD/MAS, FD involving the proximal femur, ≥1 X-ray available and age <30 years were included. X-rays were scored for the neck-shaft angle (NSA). Varus deformity was defined as NSA <110o or >10o below age-specific values...

INTRODUCTION AND IMPORTANCE: Multiple epiphyseal dysplasia, which affects the epiphysis of long bones, can show autosomal dominant and autosomal recessive inheritance patterns (Ballhausen et al., 2003 [1]). The symptoms typically appear in childhood, although they sometimes do not show symptoms until adulthood. The goals of treatment in children are to prevent the early onset of osteoarthritis, improve function, and educate patients and their families about the natural history and genetic basis of the disease...

BACKGROUND: Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome, caused by biallelic pathogenic mutations in the proteoglycan 4 (PRG4) gene, is characterized by early-onset camptodactyly, noninflammatory arthropathy, coxa vara deformity, and rarely, pericardial effusion. This syndrome can mimic juvenile idiopathic arthritis. CACP syndrome is caused by mutations in the proteoglycan 4 (PRG4) gene. To date, only 36 pathogenic mutations have been reported in this gene, but none have been reported from Azerbaijan...

BACKGROUND: The quality of reduction is an important factor affecting clinical outcomes for displaced femoral neck fractures (FNFs). However, concerns remain about the invasiveness of open reduction and internal fixation (ORIF) as compared to that of closed reduction and internal fixation (CRIF), and the choice between ORIF and CRIF as an optimal treatment strategy for displaced pediatric FNF remains controversial. MATERIALS AND METHODS: MEDLINE, Embase, and the Cochrane Library were systematically searched for studies published up to December 22, 2022, that compared ORIF and CRIF techniques for treating FNF in children...

Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome is a rare genetic disease characterized by tetrad camptodactyly, noninflammatory arthropathy, coxa vara deformity, and pericardial effusion. Arthropathy typically affects large joints and presents with joint swelling in the absence of other signs of inflammation. We described the case of a girl affected by CACP syndrome caused by a novel compound heterozygous variant in proteoglycan 4 gene (c.2831_2832insT; c.3892C > T) and associated with temporomandibular involvement...

With the rise in the prevalence of hip arthroscopy, patient selection and proper surgical execution are key to achieving excellent outcomes. As our understanding of femoral acetabular impingement grows, so does our surgical indications to achieve excellent surgical outcomes. Some impingement pathologies are amenable to arthroscopy alone and those with excessive version, dysplasia, Perthese, protrusio, and coxa-vara, or valga require an isolated or combined osteotomy. The version of the femur is known to be a significant source of impingement, and its impact on arthroscopic surgical outcomes has long been assumed to be inconsequential...

Coxa vara and shepherd's crook deformity represent the most common femoral deformities in patients affected by polyostotic fibrous dysplasia (PFD) and McCune Albright syndrome (MAS). The tibia is also commonly affected, with antero-medial bowing and valgus deformity. Surgical treatment of these deformities are technically demanding and, in most cases, intramedullary nails are the preferred method to stabilize corrective osteotomies. Genu valgus may also be present, as a residual defect after the surgical correction of the aforementioned deformities...

BACKGROUND: Metaphyseal chondrodysplasias are a heterogeneous group of diseases characterized by short and bowed long bones and metaphyseal abnormality. The aim of this study is to investigate the genetic etiology and prognostic findings in patients with metaphyseal dysplasia. METHODS: Twenty-four Turkish patients were included in this study and 13 of them were followed for 2-21 years. COL10A1, RMRP sequencing and whole exome sequencing were performed. RESULTS: Results: Seven heterozygous pathogenic variants in COL10A1 were detected in 17 patients with Schmid type metaphyseal chondrodysplasia(MCDS)...

INTRODUCTION: Femoral neck fracture is one of the most common orthopaedic traumas affecting the elderly population. The standard treatment method is hip hemiarthroplasty and total hip arthroplasty. In hip hemiprostheses surgeons mainly have to reconstruct the femoral offset and limbs' length to obtain the correct gait biomechanics and a satisfactory surgical outcome.The aim of this study is to examine the radiological results of patients after hip hemiarthroplasty for femoral neck fracture and to evaluate the reconstruction of the femoral offset using standard neck angle stems...

BACKGROUND: Legg-Calvé-Perthes disease (LCPD) is a childhood hip disease characterized by osteonecrosis of the femoral head. Because severe deformity of the femoral head can cause secondary osteoarthritis in adulthood, progressive collapse should be prevented in children with a necrotic epiphysis. The prognosis of patients with LCPD generally worsens as the age at disease onset increases, and the appropriate treatment for late-onset LCPD remains unclear. Based on the limited effect of nonoperative treatment using a nonweightbearing brace, flexion varus osteotomy (FVO) was introduced in 2010 as an initial treatment for late-onset LCPD in place of brace treatment, which we used in our institution before that time...

Camptodactyly-arthropathy-coxa vara-pericarditis syndrome (CACP) is a joint disease caused by a lack of lubricin, resulting in failed lubrication and abnormal deposition at the cartilage surface. Injection of recombinant lubricin (R-LUB) is a promising approach to improve the symptoms of the disease. However, the antifouling and lubrication properties of R-LUB on cartilage surfaces have not yet been studied. Here, the adsorption and lubrication behavior of a type II collagen (COL II) mimicking the cartilage surface upon R-LUB injection was followed by surface plasmon resonance spectroscopy and surface forces apparatus...

Methods: The clinical data of 16 patients with complicated subtrochanteric femoral fractures (Seinsheimer type Ⅲ-Ⅴ) treated with lateral decubitus position assisted plate internal fixation through a lateral incision to assist reduction combined with intramedullary nail between September 2017 and August 2020 were retrospectively analyzed...

The rare case of a 5‑year-old girl with autosomal dominant osteopetrosis type 2, who suffered metaphyseal fractures of the femoral neck on both sides within 6 months is described. On the right side, the diagnosis was made 3 months after the onset of symptoms, so that a coxa vara occurred. The treatment was surgically treated through a valgus osteotomy with fixation of the femoral head with K‑wires. Three months after the operation, the girl complained of a painful restriction of movement on her left side...

OBJECTIVE: This study aims to investigate the reliability and clinical outcome of a newly developed classification system for patients with fibrous dysplasia (FD) of the femur and adjacent bones, optimizing its evaluation and management. METHODS: A total of 205 patients (121 female and 84 male) with FD in the femur and adjacent bones were included in this retrospective study. All affected femurs were measured and treated based on this classification at our institution between 2009 and 2019...

Treatment of femoral neck fractures secondary to osteopetrosis is an uncertain and puzzled decision. Experience in the treatment, especially in the pediatric population, is scarcely reported. The duration of conservative treatment is prolonged and poses the risks of non-union and development of coxa vara deformity. The recommended treatment is closed reduction and internal fixation; however, surgery on osteopetrotic bone is challenging due to defective bone marrow function, delayed consolidation and higher risk of intraoperative fractures...
