Avascular caput necrosis

There are still many unresolved problems in the treatment and prognosis of nondisplaced femoral neck fractures, such as nonunion and avascular necrosis of the caput femoris .In order to reduce the risk of various complications after non-displaced femoral neck fractures, the caput femoris posterior tilt of femoral neck fractures and its impact on prognosis have attracted more and more attention. A large number of scholars' studies have found that when the posterior tilt exceeds 20°, the risk of internal fixation failure increases significantly...

AIMS: The aim of this study was to compare outcomes of guided growth and varus osteotomy in treating Kalamchi type II avascular necrosis (AVN) after open reduction and Pemberton acetabuloplasty for developmental dysplasia of the hip (DDH). METHODS: This retrospective study reviewed patients undergoing guided growth or varus osteotomy for Kalamchi type II AVN between September 2009 and January 2019. All children who had undergone open reduction and Pemberton acetabuloplasty for DDH with a minimum two-year follow-up were enrolled in the study...

BACKGROUND: Osteonecrosis of the femeral head (ONFH) occurs predominantly in young- and middle-aged people, and the disability rate is high in the late stage of the disease and most patients have to undergo total hip replacement. Clinically, increasing attention is paid to intervening early and middle-stage ONFH so as to delay its progress. Acupuncture and moxibustion (AM) is a unique method for treating ONFH in China. This study aims to summarize the advantages of AM for the treatment of ONFH...

OBJECTIVES: Proximal femoral plating serves as a good alternative for the fixation of femoral neck fractures, but fixation loss still occurs. This study aimed to evaluate the effect of a hybrid configuration of short- and long-threaded cannulated screws in proximal femoral plating in terms of decreasing varus collapse of femoral neck fractures. MATERIALS AND METHODS: We retrospectively analyzed 86 patients with femoral neck fractures who were fixed by proximal femoral plating from January 2015 to June 2019...

Objective The study was aimed to compare the outcome of Salter's and Pemberton's osteotomy to achieve adequate acetabular coverage in the open reduction of developmental dysplastic hips (DDH). The functional outcome was evaluated as measured on Bhatti's Functional Score System (BFSS). Patients and methods The study includes 60 children with 82 hips of developmental dysplasia in walking-age children. They were operated on for open reduction and Salter's or Pemberton's pelvic osteotomy to achieve concentric anatomical reduction with good anterolateral coverage of the femoral head...

INTRODUCTION: Severe valgus-impacted femoral neck fractures are associated with femoral neck shortening (FNS). However, no study has focused on the effect of reduction for severe valgus impaction in terms of healing and restoration of the femoral neck length. This study aimed to compare FNS and treatment outcomes of in situ fixation and fixation after reduction for severe valgus-impacted femoral neck fractures in patients aged 65 years or younger. METHODS: This retrospective study included 55 patients who underwent internal fixation with three parallel screws for femoral neck fractures with valgus impaction >15° (AO/OTA classification 31-B1...

INTRODUCTION: The Taperloc® Complete femoral stem (Zimmer Biomet, Warsaw, Indiana) builds on the widespread clinical success of the original Taperloc design used since 1982. Enhancements to the Complete design include a lowered caput-collum-diaphyseal (CCD) angle from 138° to 133° for improved offset, optimized neck taper with polished neck flats to increase range of motion, reduced distal geometry to improve proximal canal fill, and gradual off-loading that is the goal of tapered geometry...

OBJECTIVE: The purpose of this study is to determine the efficacy of the open reduction and fixation of a dislocated proximal humerus fracture with a locking plate, also evaluating the incidence of complications and functional recovery of the shoulder. A retrospective study focusing on patients who had suffered a fracture of the proximal humerus and were treated by means of an open reduction and internal fixation with a locking plate, using either the Philos or the LPHP plate. We have also included a comparison of these two plates...

A total of 102 children and adolescents, 27 girls and 75 boys of the median age of 10.9 years, were treated for injuries to the proximal humerus at the PediatricTrauma Centre of the Clinic of Pediatric Surgery and Traumatology in Brno over the period of 1993-1997. A conservative approach was indicated in 51 cases (50%), percutaneous pinning after conservative reduction in 50 cases (49%) and an open surgical approach in one case (1%). In 97 patients the treatment results were evaluated as excellent, in 5 patients as good...

INTRODUCTION: Severe slipped capital femoral epiphysis inevitably results into arthritis, making surgical recovery of normal anatomy an attractive objective. This can be achieved by the procedure described by Dunn. However, all published studies report a risk of avascular necrosis. MATERIAL AND METHODS: The present series assembles 25 adolescent cases aged 10 to 15 years. There were 16 cases of chronic pure displacement with several months' evolution, including nine exacerbated by an acute accident...

A 3-year-old boy had pain on the medial side of his left knee after his father fell on him. When the pain still persisted 4 days later, further diagnostics revealed dislocation of the hip. The pain disappeared and function was restored after closed reposition under fluoroscopic control followed by immobilisation with a plaster cast. Traumatic dislocation of the hip in childhood is a relatively rare injury, but may have far-reaching consequences. As the sensitivity to pain in children differs from that in adults, an examiner must be on the alert for a traumatic dislocation of the hip whenever a child presents with a fitting history and dysfunction ofthe leg, regardless of the localisation of the pain...

The aim of this study was to report on the long-term follow-up of haemophilic children with avascular femoral head necrosis and to determine whether radiographic findings at initial diagnosis have any prognostic value. Seven patients with avascular necrosis of the femoral head were clinically and radiographically observed over a period of 5-50 years. The average age of patients at first diagnosis was 7.1 years. At follow-up, three of seven patients claimed to have occasional mild pain in the affected hip, four of seven showed loss of range of motion in the hip joint and two of seven patients showed a limp...

BACKGROUND: Femoral caput necrosis is an actual therapeutic problem, because it appears mainly in mid-aged people. The necrotic focus is most often localized in the proximal and ventral parts of the femoral bone capitulum, which, from the biomechanical point of view is the most loaded part. These cases can be possibly treated by transtrochanteric rotational osteotomy. By means of this operation we rotate the necrotic focus to the less loaded part of the joint in correlation with the acetabulum...

Three young people, a boy aged 15 years and two girls aged 9 years and 13 years, had already suffered groin pain and knee pain for many months. They exhibited an antalgic walk, diminished function of the hip and radiographic signs of a slipped capital femoral epiphysis (SCFE). The complaints disappeared following in situ fixation with one or more screws. Epiphysiolysis of the caput femoris through the growth plate is a disorder of the growing hip. It is the most prevalent hip disease in adolescents. Obese boys are the most commonly affected...
