The presence of carbonic anhydrase activity was demonstrated in guinea pig skeletal muscle mitochondria purified by Percoll gradient centrifugation such that contamination by sarcoplasmic reticulum vesicles was less than 5%. Assay of purified heavy sarcoplasmic reticulum vesicles for carbonic anhydrase activity showed these to have somewhat less activity(More)
STUDY DESIGN Retrospective case-control study. OBJECTIVE To compare the efficacy of 3 blood management strategies in patients undergoing posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) in reducing donor blood transfusion. SUMMARY OF BACKGROUND DATA Although intraoperative cell salvage and predonated banked blood may be effective(More)
PURPOSE To investigate the effect of treated clubfoot disorder on gross motor skill level measured by the Alberta Infant Motor Scale (AIMS). METHODS Fifty-two babies participated: 26 were treated for idiopathic clubfoot (12 with the Ponseti treatment method, 9 with the French physical therapy technique, and 5 with a combination of both methods); 26 were(More)
Toe walking is a common gait deviation which in the absence of a known cause is termed idiopathic toe walking. Surgical treatment in the presence of a triceps surae contracture includes tendo-Achilles or gastrocnemius/soleus recession and has been shown to be effective in improving kinematic outcomes at a one year follow up. The purpose of this study was to(More)
BACKGROUND Distal rectus femoris transfer is a widely accepted and effective treatment for children with cerebral palsy presenting with stiff knee gait. Previous research has reported improvement in knee arc of motion regardless of transfer site; however, sample sizes and patient function were unmatched in these studies. The purpose of this study was to(More)
Duplication of the spine is a rare malformation. A neurologically intact pediatric patient with this malformation is described here. A 6-year-old girl presented to our institution for evaluation of an asymptomatic kyphotic deformity. She denied weakness, sensory changes, and bowel or bladder complaints. Physical examination revealed mild kyphosis at the(More)
BACKGROUND Adolescent subjects with severe unilateral hip disease are often stiff and painful yet have limited surgical options. Although hip fusion has been used successfully to minimize pain, acquired gait compensations after arthrodesis are factors felt to lead to knee and back pain over time. However, these gait compensations may already be present in a(More)
Most patients (95%) with fibular hemimelia have an absent anterior cruciate ligament (ACL). The purpose of this study was to assess the long-term outcome of such patients with respect to pain and knee function. We performed a retrospective review of patients with fibular hemimelia and associated ACL deficiency previously treated at our institution. Of a(More)
BACKGROUND Ambulatory children with cerebral palsy (CP) often present with multiple deviations in all planes including increased internal hip rotation during gait. Excessive femoral anteversion is a common cause of deviation managed surgically with an external femoral derotational osteotomy (FDO). The purpose of this study was to evaluate the gait and(More)
BACKGROUND Most patients with idiopathic clubfeet require a percutaneous tendoachilles tenotomy to correct residual equinus deformity. This procedure is typically performed with the child awake in an outpatient setting. Percutaneous tendoachilles tenotomy under general anesthesia offers the potential advantages of better pain control, the ability to perform(More)
