Neonatal Necrotizing Fasciitis of the Foot Caused by Bacillus cereus: A Case Report.

Few neonatal cases of soft tissue and osteoarticular infections with have been reported. We report a rare clinical presentation of necrotizing fasciitis of the foot caused by in a 17-day-old male neonate with hypoplastic left-sided heart syndrome. Fulminant progressive black skin necrosis was triggered by fresh frozen plasma leakage from the peripheral venous access.

Periosteal Stripping and Periosteal Division for Leg Length Discrepancy After Proximal Femoral Intertrochanteric Osteotomy for Perthes Disease.

Background and objective Periosteal stripping and periosteal division (PSPD) can help promote the growth of the long bone in children with leg length discrepancy (LLD). We performed PSPD in a cohort of patients when LLD was observed at the time of implant removal surgery after proximal femoral osteotomy for Perthes disease. This study aimed to clarify the efficacy and safety of PSPD for acquired LLD related to Perthes disease.

Reapplication of the Pavlik Harness for Treatment of Developmental Dysplasia of the Hip After Initial Pavlik Harness Failure.

Objective: The Pavlik harness (PH) has been widely used as the standard treatment for infants with developmental dysplasia of the hip (DDH). When the initial application of the PH fails, alternative treatments, such as closed reduction, open reduction, and reapplication of the PH will be considered. Compared with other treatments, reapplication of the PH offers certain advantages, including simplicity and reduced physical, and psychological stress, on both infants and caregivers.

Radiologic Changes After 10 Years Postreduction in Developmental Dysplasia of the Hip Treated With Different Reduction Methods and Risk Factors for Osteoarthritis.

Background: This study examined how radiologic indices at 10 years postreduction change over time and influence the final outcome through a comparative study of 3 reduction methods for developmental dysplasia of the hip, including the Pavlik harness, closed reduction, and open reduction (OR).

Methods: Patients treated from 1990 to 2000 for dysplasia of the hip and followed up for >20 years were included in this study. Radiologic indices at 10 years postreduction and final follow-up (average 24 years postreduction) were measured in the 3 groups.

Radiological results of Shelf acetabuloplasty in adolescent hip dysplasia with aspherical femoral head: how to get an ideal placement of the Shelf graft.

Shelf acetabuloplasty continues to be effective in the prevention or delay of osteoarthritis in adolescent dysplastic hips. We aimed to evaluate the efficacy and to determine the correct level of the bone graft objectively. We retrospectively analyzed 16 hips underwent Shelf acetabuloplasty originated by Spitzy.

Single Versus Combined Procedures for Severely Involved Legg-Calvé-Perthes Disease.

Background: The concept of containment as an effective approach to reduce the risk of femoral head deformity has been questioned because modest results have been achieved after nonoperative and operative treatments for severely involved Legg-Calvé-Perthes disease. Several reports have shown the limited effectiveness of some conventional single procedures. However, there is limited data on the effectiveness of combined procedures.

Lateral insertion is a good prognostic factor after in situ fixation in slipped capital femoral epiphysis.

Background: In situ fixation (ISF) is standard treatment for slipped capital femoral epiphysis (SCFE) to stabilize the epiphysis and to prevent further slip. The aim of this study was to clarify the incidence of slip progression after ISF and its prognostic factors.

Methods: We retrospectively reviewed 53 hips in 49 consecutive SCFE patients who underwent single screw ISF and were followed until physeal closure.

Outcome of patients with Legg-Calvé-Perthes onset before 6 years of age.

Background: The prognosis of Legg-Calvé-Perthes disease (LCPD) in young patients has been accepted as favorable. The purpose of this study was to clarify the outcome of LCPD patients with onset before 6 years of age.

Methods: From 1989 to 2007, of 332 LCPD patients, 114 hips (in 100 patients) were diagnosed before 6 years of age (mean age, 4.

Postoperative improvement of femoroacetabular impingement after intertrochanteric flexion osteotomy for SCFE.

Background: Patients with slipped capital femoral epiphysis (SCFE) may develop cam-type femoroacetabular impingement (FAI). Early management of FAI has been advocated for patients with symptomatic FAI. The various treatment options, including reorientation surgeries, realignment procedures, and osteoplasty, remain controversial.

Remodeling of angulation deformities in diaphyseal femoral fracture in children.

Background: The purpose of this study was to reconsider the factors influencing the remodeling effects in diaphyseal femoral fractures in children based on radiological results.

Patients And Method: We reviewed 39 patients with more than a 5° residual angulation deformity at the fracture site on anteroposterior and/or lateral views at the primary healing stage. The average follow-up period was 30.

Evaluation of behavior and neuropeptide markers of pain in a simple, sciatic nerve-pinch pain model in rats.

Pathomechanisms of injured-nerve pain have not been fully elucidated. Radicular pain and chronic constriction injury models have been established; however, producing these models is complicated. A sciatic nerve-pinch injury is easy to produce but the reliability of this model for evaluating pain behavior has not been examined.

A case of spontaneous hemoarthrosis after a total knee arthroplasty.

A 63-year-old woman with osteoarthritis had undergone right total knee arthroplasty. Nineteen months later, the patient presented with a recurrent hemoarthrosis. Open arthrotomy revealed hypertrophic synovium with small clots in the suprapatellar pouch, but entrapment of synovial tissues could not be observed.
