BACKGROUND: Calcaneal lengthening has been used to correct planovalgus foot deformities in patients with cerebral palsy (CP). QUESTIONS/PURPOSES: This study was performed to investigate the amount of correction that can be achieved after calcaneal lengthening for the treatment of a planovalgus deformity in patients with CP and to provide cutoff values based on the preoperative radiographic measurements that suggest additional procedures to achieve satisfactory correction. METHODS: Seventy-five c

This study investigates the overall rate of urinary retention in a large cohort of unselected orthopaedic patients who had either general or regional anesthesia and defines the risk factors for postoperative urinary retention in that cohort of patients. A total of 15,681 patients who underwent major orthopaedic surgery with general or spinal/epidural anesthesia were included. Postoperative urinary retention was defined as any patient who required a postoperative consultation to the urologic depa

Level III.

This study was carried out to determine parenting stress levels in the parents of children with cerebral palsy (CP) and to examine the factors that contribute to the parenting stress score. Parenting stress levels were assessed in 101 parents of children with CP (mean age 8.8 years, SD 2.1) using the parenting stress index (PSI). The extent of involvement, gross motor function classification system, and pediatric outcomes data collection instrument were collected for patients' information. The r

AIM: This study was undertaken to determine the need for concurrent prophylactic femoral varization osteotomy (FVO) of contralateral stable hips at the time of hip reconstructive surgery on unstable hips in non-ambulant individuals with cerebral palsy (Gross Motor Function Classification System levels IV and V). METHOD: A decision analysis model was constructed that included (1) the probability of unstable hips during observation of the contralateral stable hips, (2) unstable hip rate (subluxati

BACKGROUND: This study was performed to evaluate the rebound phenomenon after the correction of coronal angular deformity by hemiepiphysiodesis using tension band plate in children and to identify its risk factors. METHODS: We reviewed 50 children (mean age, 11.0 ± 2.5 years) with 94 physes who had undergone hemiepiphysiodesis using tension band plate due to coronal angular deformity of the lower limb. Patients' demographic data including sex, age at initial surgery and plate removal, affected b

BACKGROUND: This study was performed to investigate the usefulness of clinical pathway (CP) using an electronic medical record (EMR) in pediatric patients undergoing closed pinning for supracondylar fracture of the humerus, by analyzing the length of hospital stay, hospital cost and satisfaction of the medical teams. METHODS: This before and after comparative study included consecutive children who underwent closed pinning for supracondylar fracture of the humerus since 2009. The pre-CP group co

This study was performed to measure the equivalent scattered radiation dose delivered to susceptible organs while simulating orthopaedic surgery using conventional and mini C-arm fluoroscopy. In addition, shielding effects on the thyroid, thymus, and gonad, and the direct exposure delivered to the patient's hands were also compared. A conventional and mini C-arms were installed in an operating room, and a hand and an operator phantom were used to simulate a patient's hand and a surgeon. Photolum

BACKGROUND: Although several studies have investigated the outcomes after distal hamstring lengthening (DHL), no study has undertaken an approach that included all or most of the important factors that could influence the results. This study was performed to evaluate the outcomes after DHL and analyze the factors that influence the improvement and serial change in knee motion after surgery in patients with cerebral palsy (CP), using a linear mixed model (LMM). METHODS: The study included 314 amb

The aim of this retrospective study was to determine the short-term effects of proximal femoral derotation osteotomy (FDO) on gait in 53 ambulatory patients with spastic diplegia controlling all confounding procedures. All patients showed a jump gait pattern and had undergone bilateral rectus femoris transfer, distal hamstring lengthening, and tendo-Achilles lengthening as a single-event multilevel surgery. Of these, additional bilateral proximal FDOs were included in 25 patients, defined as the
