BACKGROUND The aim of this study was to contrast the collapse values of the postoperative weight-bearing areas of different tantalum rod implant positions, fibula implantation, and core decompression model and to investigate the advantages and disadvantages of tantalum rod implantation in different ranges of osteonecrosis in comparison with other methods. MATERIAL AND METHODS The 3D finite el...

Enchondroma represents a common bone tumor of the hand. The scaphoid is a rare location. We report the case of a scaphoid enchondroma presenting as chronic wrist pain following a relatively minor trauma. The diagnosis was suggested by radiological study and then confirmed by histological study after biopsy. Enucleation and vascularized bone graft with osteosynthesis provided good results. The c...

OBJECTIVE To compare the occurrence of thrombophilic disorders in patients with idiopathic osteonecrosis of the femoral head and patients with secondary osteonecrosis of the femoral head. METHODS Twenty-four consecutive patients were enrolled, with eight of them presenting idiopathic osteonecrosis and 16 presenting secondary osteonecrosis. The tests for detection of thrombophilic disorders we...

Although the association between chronic, high-dose corticosteroid use and osteonecrosis is well known, the incidence of osteonecrosis following short-term, low-dose steroid taper packs has never been reported across a large population. The goal of this study was to report the incidence and risk of osteonecrosis after methylprednisolone taper pack (MTP) prescriptions in a multicenter electronic...

<p class="abstract">Osteonecrosis of the femoral head, can be secondary to various causes, which traumatic or atraumatic. The corticosteroid used is a common cause non-traumatic osteonecrosis. Various viral infections have been documented osteonecrosis, none studies report COVID-19. 23-year-old gentleman diagnosed with He received steroid injections as part treatment. Nearly after two mon...

Introduction Scaphoid fractures are the most common type of hand fracture. Traditionally, non-displaced fractures of the scaphoid have been treated conservatively, with the immobilisation of the hand with a cast; hence, surgical fixation of the fracture has become increasingly popular because of quicker re-mobilisation and return to its original function. However, this was balanced against the ...

Avascular necrosis (AVN) of the scaphoid secondary to corticosteroid use is a rare entity. Previous reports in the literature refer to chronic steroid intake. We report a case secondary to low dose, short term use. AVN has a multifactorial cellular and genetic aetiology and most frequently affects the femoral head. Diagnosis relies on a high index of suspicion and early magnetic resonance (MR) ...

We describe the use of a vascularised periosteal patch onlay graft based on the 1,2 intercompartmental supraretinacular artery in the management of 11 patients (ten men, one woman) with chronic nonunion involving the proximal third of the scaphoid. The mean age of the patients was 31 years (21 to 45) with the dominant hand affected in eight. Six of the patients were smokers and three had underg...

Coagulation alterations may be involved in osteonecrosis in childhood acute lymphoblastic leukemia. Retrospectively, we evaluated the available coagulation parameters at diagnosis and during induction treatment of 161 acute lymphoblastic leukemia patients: 24 with symptomatic osteonecrosis (median age: 13.8 years, range 4.0-17.2) and 137 without osteonecrosis (median age: 4.9 years, range 1.0-1...

background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures.   methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...
