Theoretical Comparison of the Methods of Surgical Treatment of Deforming Arthrosis of the Knee Joint

Comparison of the techniques of valgus osteotomy with resection osteotomy of the fibula in combination with sanitation arthroscopy. Resection of the fibula, debridement arthroscopy is characterized by minimally invasiveness, targeted therapeutic effect on the focus of destruction of the cartilaginous cover, removal of inflammatory mediators with abundant lavage, low-trauma intervention. Abrasive chondroplasty, subchondral tunneling during arthroscopy make it possible to create conditions for reparative processes, and the formation of hyaline-like cartilage in the defect zone. Corrective osteotomy may result in fractures of the tibial plateau, fractures of the cortical loop (instability of fixation), false joints, and fractures of metal structures.

Addressing a Complex Proximal Femoral Deformity With Custom Cutting Guides Using 3D-Computer Design Software: A Case Report and 2-year Follow-Up

We report a case of a 23-year-old female with a history of congenital proximal femoral deformity and malunion of a prior proximal femoral corrective osteotomy, who presented seeking treatment for debilitating end-stage arthritis of her hip. Consideration for total hip arthroplasty (THA) for this patient was complicated by her young age and the complexity of her proximal femoral deformity. A 3-dimensional bone model of the patient’s femur was created using digital reconstructive software based on preoperative CT-imaging and used to plan our corrective osteotomy and arthroplasty component specifications. Using the detailed characterization of the femoral morphology, custom cutting guides were designed to fit uniquely into the correct position and ensure a high degree of accuracy with our osteotomy cuts. This unique case highlights the use of 3D-modeling software and printing technology for detailed surgical planning and precise execution in patients with complex deformities or otherwise abnormal anatomy.

Single-stage surgical correction of a bilateral acquired coxa vara deformity in a young woman

A 23-year-old female-treated patient of osteomalacia and secondary hyperparathyroidism with hypophosphatemia presented with a 5-year history of bilateral groin pain and stiffness of both hips and difficulty in walking. Plain radiographs of the pelvis showed bilateral coxa vara deformity. She was managed surgically by a single-stage bilateral subtrochanteric corrective osteotomy with the internal fixation. After the osteotomy healing at 3 months, the patient was pain free and walked comfortably with an increased range of hip motion.

Fibrocartilagenous dysplasia in distal femur: A rare histopathological finding

Fibrocartilaginous dysplasia (FCD) or massive cartilaginous differentiation in fibrous dysplasia are interchangeably used terms. It is a rare variant of fibrous dysplasia (FD) which is benign, lytic, and expansile bone lesion and causes progressive deformity in the bones and may lead to pathological fracture. Radiologically, FCD may confused with cartilaginous benign and malignant bone tumours. FCD usually shows calcification in imaging. Surgical curettage or corrective osteotomy and histopathological examination of these lesions is necessary to differentiate it from other cartilaginous tumours. Here we report case of fibrocartilaginous dysplasia of distal femur in a 4-year-old male child.

Congenital Distal Tibiofibular Synostosis - A Case Report

Congenital tibiofibular synostosis is the fusion of tibia and fibula since birth. So far there are many reports of congenital proximal tibio fibular synostosis in English literature, but congenital distal tibio fibular synostosis is very rarely described. Imaging studies by means of X rays, CT and MRI are required to rule out osteochondromas arising from distal tibia, fibula and other conditions. If the patient is symptomatic by means of deformity surgical intervention in the form of corrective osteotomy may be considered to prevent alternation of joint biomechanics. We report a rare case of congenital distal tibiofibular synostosis in a 21 year old female presented with complaints of deformity and pain on and off in left lower leg since childhood. Key words: Congenital; Synostosis; Deformity; Osteochondroma.
