Femoral head avascular necrosis

P Mörsdorf, A Lauer, T Histing, T Pohlemann, M Burkhardt
Traumatic hip dislocations in children are not frequent but constitute true emergencies. They require urgent reduction because of the risk of consecutive avascular necrosis of the femoral head. We report a 6-year-old boy with traumatic posterior hip dislocation on a vacation abroad. After closed reduction the day of the accident, a hip spica cast was applied and the patient was transferred home. Once home, X‑ray and CT diagnostics were completed by MRI. In future, long-term clinical and radiological investigations for avascular necrosis and growth disorders, as well as thoroughly informing the parents, should be mandatory...

Traumatic hip dislocation is uncommon in children. Yet, it represents an orthopaedic emergency, because delayed treatment can lead to avascular necrosis of the femoral head. In this case a four-year-old boy and an eight-year-old girl were treated in an emergency department less than two weeks apart. They both received a posterior hip dislocation after accident during sledging. Their hips were reduced within six hours in the operating theatre, and the patients were discharged few days later. At the follow-up after six and 12 weeks both patients were doing well, and X-rays were normal...

Osteoarthritis of the hip remains a prevalent disease condition that influences ever-changing treatment options. Procedures performed to correct anatomic variations, and, in turn, prevent or slow the progression of osteoarthritis, are aptly referred to as types of hip preservation surgery (HPS). Conditions that predispose individuals to femoroacetabular impingement (FAI), including pincer- and cam-type morphology, and hip dysplasia are specifically targeted in HPS. Common surgical interventions include acetabuloplasty, osteochondroplasty, periacetabular osteotomy (PAO), and derotational femoral osteotomy (DFO)...

A large number of short stem prostheses for hip -arthroplasty have been introduced in the past years. Although there is a large increase of publications about short stems, there is still little data available about survival and revision rates. We report prospectively on the outcome of 84 consecutive NANOS® short stem prostheses in 81 patients. We have included 37 female patients and 44 male patients with an average age of 61.6 ± 9.2 years. The main diagnoses were osteoarthritis in 67 patients, dysplastic osteoarthritis in 8 patients and avascular necrosis of the femoral head in 6 patients...

BACKGROUND: The modified Dunn procedure facilitates femoral capital realignment for slipped capital femoral epiphysis (SCFE) through a surgical hip dislocation approach. Iatrogenic postoperative hip instability after this procedure has not been studied previously; however, we were concerned when we observed several instances of this serious complication, and we wished to study it further. QUESTIONS/PURPOSES: The purpose of this study was to evaluate the frequency, timing, and clinical presentation (including complications) associated with iatrogenic instability after the modified Dunn procedure for SCFE...

UNLABELLED: Femoral-neck stress fractures are relatively rare and may present as sports-related injuries. The presentation is variable, and prompt diagnosis facilitates the earliest return to pre-morbid functional activity levels. Delayed detection may precipitate femoral non-union or avascular necrosis, resulting in long-term functional deficit. AIMS: We describe the clinical, diagnostic and therapeutic approach of a femoral-neck stress fracture that occurred in a 28-year-old female recreational runner...

INTRODUCTION: Intracapsular femoral neck fractures remain associated with high rates of post-traumatic femoral head necrosis, non-union, and revision surgery. AIM: Our aim was to identify factors associated with revision surgery in intracapsular femoral neck fractures treated with sliding hip screws (SHS) in adults aged <65 years. PATIENTS AND METHODS: Consecutive admissions were identified retrospectively from the Royal Victoria Hospital, Belfast, which was the largest volume hospital on the National Hip Fracture Database...

AIMS: One method of femoral head preservation following avascular necrosis (AVN) is core decompression and insertion of a tantalum rod. However, there may be a high failure rate associated with this procedure. The purpose of this study was to document the clinical and radiological outcomes following total hip arthroplasty (THA) subsequent to failed tantalum rod insertion. PATIENTS AND METHODS: A total of 37 failed tantalum rods requiring total hip arthroplasty were identified from a prospective database...

Avascular necrosis (AVN) of femoral head needs to be addressed early in the course of the disease, to prevent progression to osteoarthritis. A revascularizing procedure which can help preserve the head should be considered in young adults to alleviate the need for total hip arthroplasty. We included 40 cases (53 hips) of AVN of femoral head operated with Sartorius muscle pedicle iliac bone grafting, done by the senior author. Early post-operative rehabilitation was done. The weight bearing was delayed for 6 weeks...

BACKGROUND: We observed cases of extensive osteolysis of the femoral head following acetabular fractures even though the original fracture did not involve the femoral head or neck. This observation has been called massive osteolysis of the femoral head (MOFH). PURPOSE: To evaluate the clinical and imaging features of MOFH to gain a better understanding of its patho-etiology. MATERIAL AND METHODS: We retrospectively collected cases of acetabular fractures seen over a period of 10 years and evaluated the clinical features and imaging characteristics...

The aim of this study was to corroborate the hypothesis that Tao-Hong-Si-Wu Decoction (THSWD) affects steroid-induced avascular necrosis of the femoral head (SANFH) by regulating the hypoxia-inducible factor 1α (HIF-1α) pathway. Forty-eight New Zealand rabbits were randomly divided into a normal control group (NC group), a model group (SANFH group), a THSWD group, and a dimethyloxalylglycine group (DMOG group). Rabbits in the SANFH group were injected with both horse serum and methylprednisolone. Rabbits in the THSWD group were gavaged with THSWD in addition to receiving the same treatment as the SANFH group...

Liver transplantation provides an important, often life-saving treatment for end-stage liver disease. Osteoporosis post-liver transplantation has been described in adults; however, this has not been described in the pediatric population to date. We present a case of a 13-year-old female patient who underwent an orthotopic liver transplant for cryptogenic liver cirrhosis. Her immunosuppressants were tacrolimus and prednisone. Four months posttransplant, she started complaining of bilateral lower limb pain and limping while walking, progressing to a point where she was almost immobile...
