Case Reports
Pyomyositis of the obturator internus muscle extending to septic arthritis of the hip in a child: a case report.
We report a case of primary pyomyositis in the obturator internus muscle. Pyomyositis involving muscles around the hip needs to be differentiated from septic arthritis because these infections show similar symptoms. ⋯ Uncontrolled pyomyosistis can cause sequelae such as septic shock, osteomyelitis of adjacent bone, and septic arthritis. Awareness of this condition will facilitate correct diagnosis and early treatment.

Several studies recently reported the usefulness of plating methods following limb lengthening with external fixators. This study describes modification at the time of plate insertion, selection of a locking plate, and the direction of plating. From April 2006 to July 2009, 12 consecutive patients, mean age 17.8 years, were enrolled in the study. The mean follow-up period was 36.5 months. All lengthening procedures were performed at the tibia. After proximal tibial osteotomy, a monoaxial external fixator was maintained on the lateral side of the tibia. At the end of distraction, a manually bent locking plate was inserted on the anteromedial side of the tibia, and the external fixator was removed. The mean final lengthening amount was 4.23 cm (range, 3.6-5.0 cm). The mean duration of the external fixator was 54.9 days (range, 47-67 days) and the mean external fixator index was 13.0 days/cm (range, 12.3-14.4 days/cm). The mean time to bony consolidation was 195.7 days (range, 150-264 days) and the mean healing index was 46.1 days/cm (range, 38.4-55 days). There were only minor complications in four patients. This case series showed that, especially with tibia lengthening, our method allows for successful early removal of the external fixator as compared with other methods (plating after lengthening), is associated with fewer complications, and is an effective alternative. ⋯ Therapeutic Level IV.

Surgery for myelomeningocele spinal deformity is accompanied by a high rate of complications. These include infection, pathological skin breakage, instrumentation failure, and neurological deterioration. The four-rib construct associated with the percutaneous technique in immature children with myelomeningocele and spinal deformity is introduced. ⋯ The four-rib construct technique can be considered as a potential surgical option in (powered by Editorial Manager and Preprint Manager; Aries Systems Corporation) treating spinal deformity associated with myelomeningocele, but still more patients with long term follow-up are needed to prove the efficacy of this procedure. The four-rib construct is simple, minimally invasive, and does not exclude alternative treatment. Moreover, the incidence of complications associated with the four-rib construct compares favorably with other growth techniques.

Traumatic spondylolisthesis is a rare injury resulting from complex trauma and high-energy mechanisms. We present a case report of traumatic spondylolisthesis at the L5-S1 disc space of a patient who was buried after a wall fell on his back. ⋯ Surgical treatment was provided with a posterior and anterior approach using pedicle fixation and an anterior cage. After 4 months, there was significant recovery of muscle strength in the lower limbs.

A 12-year-old boy presented to our emergency department complaining of pain and functional limitation on his right ankle after an indirect trauma. Plain radiographs were taken identifying a type II epiphysiolysis of the distal tibia and a proximal fibula fracture. ⋯ This fracture pattern has not been described by the Dias-Tachdjian classification. It is important to bear in mind that, based on the need for osteosynthesis for the epiphysiolysis, the treatment of these fractures in children usually differs from that in the adults as no transyndesmal screw fixation is required.
