There is some clinical evidence to suggest that fractures of long bones heal more rapidly in patients with severe head injury or acute traumatic spinal cord injury. The mechanism underlying this orthopedic phenomenon is not well understood. The aim of the current study was to investigate the bone healing of diaphyseal femoral fractures in patients with concomitant head or spinal cord injuries a...

Objective :The objective of this study is preserving the joint by preventing the collapse of femoral head in Osteonecrosis of femoral head (ONFH) Methods :In this study patients with early ONFH are treated with core decompression and augmented with bone marrow aspirate concentrate spread on a collagen scaffold . Results : Core decompression augmented with bone marrow aspirate concentrate seems ...

Osteochondral defects of the femoral head are rare and principles of treatment include anatomic reduction, rigid fixation, enhancement of blood supply, and restoration of articular congruity. In this report, we present a case where the defect of the femoral head was treated with surgical dislocation of hip anteriorly and mosaicplasty. At 3-year follow-up, the patient was symptom free with...

We report the case of a 42-year-old male who suffered a fracture-dislocation of the femoral head. After a closed reduction of the hip, this proceeded to an open reduction with internal fixation of the fractured femoral head, in addition to labral repair and micro-fracture of an articular cartilage defect. After considering the risks to the femoral head blood supply, the trochanteric flip osteot...

In this study, we investigated the feasibility and safety of intravenous transplantation of allogeneic bone marrow mesenchymal stem cells (MSCs) for femoral head repair, and observed the migration and distribution of MSCs in hosts. MSCs were labeled with green fluorescent protein (GFP) in vitro and injected into nude mice via vena caudalis, and the distribution of MSCs was dynamically monitored...

In situ stabilization remains the standard of care in the treatment of stable slipped capital femoral epiphysis (SCFE). Screw placement perpendicular to the physis has shown satisfactory results with minimal complications. A prominent screw head may produce femoral acetabular impingement and pain after in situ fixation in severe SCFE. We performed a biomechanical study to establish whether scre...

BACKGROUND Subcapital femoral neck is known to cause many complications, such as avascular necrosis (AVN) of the femoral head or nonunion, compared with other femoral neck fractures. The purpose of this study was to analyze the incidence of AVN and fixation failures in patients treated with internal fixation using cannulated screws for the subcapital femoral neck fractures. METHODS This study...

Fig. I the reduction is confirmed by an intra-operative roentgenogram. However, there are some cases in which the relationship between the femorab head and the acetabubum cannot be readily discerned from these films ; either because the femoral head is not yet ossified, or because the films are not of sufficiently high quality. Lack of clarity may stem from poor radiological equipment, but some...

The loss of trial femoral head in the soft tissues is a rare per operative complication in total hips replacement. We report the loss of the femoral head in surrounding hip joint soft tissues and unsuccessful attempts to locate and remove it. Surgeons should be aware of such complication as trial femoral heads usually are made from non radiolucent material and cannot be detected by regular x-ra...
