Purpose

The incidence of hip displacement in children with cerebral palsy is approximately 30% in large population based studies. The purpose of this study was to report the long-term effect of hip surgery on the incidence of hip displacement using a newly validated Cerebral Palsy (CP) hip classification.

Method

Retrospectively, a sub-group of 100 children who underwent surgery for hip displacement were identified from a large-population based cohort of children born with CP between January 1990 and December 1992. These children were followed to skeletal maturity and closure of their tri-radiate cartilage. All patients returned at maturity for clinical and radiographic examination, while caregivers completed the disease specific quality of life assessments. Patients were grouped according to motor disorder, topographical distribution and GMFCS. Radiographs were independently graded according to CP hip classification scheme to ensure reliability. Surgical Failures were defined as CP Grade > IV.

Purpose

Pediatric tibial shaft fractures (TSF) account for 15% of long bone fractures in children. Compartment syndrome (CS) is difficult to diagnose in children, often leading to disastrous outcomes. This study investigated the incidence of CS in TSF and its associated risk factors.

Method

A detailed five-year retrospective chart review of TSF treated at a major pediatric hospital. CS was diagnosed clinically or by intra-compartment pressure. Multivariate logistic regression analysis tested age, gender, mechanism of injury, time to surgery, fracture type, and treatment intervention as possible risk factors for CS.

Purpose

Surgical dislocation is useful for assessing and treating proximal femoral hip deformities. Legg-Calv Perthes disease (LCPD) causes proximal femoral growth deformity, resulting in reduced femoral head-neck offset and femoracetabular incongruity. The purpose of this study was to demonstrate the efficacy and report the short-term results of surgical hip dislocation for the treatment of adolescents with healed LCPD.

Method

This retrospective review included 29 adolescents [19 males and 10 females, age 17 (range nine-35)] with LCPD, who underwent surgical hip dislocation between January 2001 and December 2009. All subjects had a clear diagnosis of LCPD, pre and postoperative WOMAC scores and at least one year of clinical and radiographic follow up. In addition to surgical dislocation, all patients underwent femoral head-neck osteoplasty, 21 underwent relative femoral neck lengthening and trochanteric transfer, 12 underwent intertrochanteric osteotomy and seven had labral debridement. The average follow-up was three years from the time of surgical intervention.

We studied the prevalence of severe crouch gait over a 15-year period in a defined population of children with spastic diplegia and Gross Motor Function Classification System levels II and III, to determine if there had been a decrease following changes to the management of equinus gait. These changes were replacing observational with three-dimensional gait analysis, replacing single level with multilevel surgery, and replacing gastrocsoleus lengthening with gastrocnemius recession. Of 464 children and adolescents with spastic diplegia who underwent three-dimensional gait analysis, 27 had severe crouch gait. Seventeen of these had been managed by isolated lengthening of the gastrocsoleus. Following changes in the management of equinus gait, the prevalence of severe crouch gait decreased from 25% and stabilised at a significantly lower rate, fluctuating between 0% and 4% annually (p < 0.001).

We conclude that severe crouch gait in this population was precipitated by isolated lengthening of the gastrocsoleus. These findings may be relevant to other surgical populations, as severe crouch gait may be a useful way to monitor the quality of the surgical management of abnormal gait in children with cerebral palsy and spastic diplegia.

We have tested the reliability of a recently reported classification system of hip morphology in adolescents with cerebral palsy in whom the triradiate cartilage was closed. The classification is a six-grade ordinal scale, based on the measurement of the migration percentage and an assessment of Shenton’s arch, deformity of the femoral head, acetabular deformity and pelvic obliquity.

Four paediatric orthopaedic surgeons and four physiotherapists received training in the use of the classification which they applied to the assessment of 42 hip radiographs, read on two separate occasions. The inter- and intra-observer reliability was assessed using the intraclass correlation coefficient and found to be excellent, with it ranging from 0.88 to 0.94. The classification in our study was shown to be valid (based on migration percentage), and reliable. As a result we believe that it can now be used in studies describing the natural history of hip displacement in cerebral palsy, in outcome studies and in communication between clinicians.

Background: Post-operative analgesia using parenteral opioids or epidural analgesia can be associated with troublesome side effects.

Locally administered pre-emptive analgesia is effective, reduces central hyper sensitisation and avoids systemic drug related side-effects and may be of benefit in total knee replacement.

Materials and Methods: 64 patients undergoing total knee replacement were randomised to receive a periarticular intra-operative injection containing ropivacaine, ketorolac, epimorphine and epinephrine or nothing.

All patients received patient controlled analgesia (PCA) for 24 hours post surgery, followed by standard analgesia. Visual Analogue Scale (VAS) pain scores during activity and at rest and patient satisfaction scores were recorded pre and post operatively and at 6 week follow up. PCA consumption and overall analgesic requirement were measured.

Results: PCA use at 6,12 and over 24 hours post surgery was significantly less in patients receiving the injection (P< 0.01, P=0.016, P< 0.01). Patient satisfaction in PACU and 4 hrs post operation was greater (P=0.016, P=0.013). VAS for pain during activity in PACU and at 4 hrs were significantly less (P= 0.04, P=0.007) in the injected group. The average ROM at 6 weeks was no different. Overall hospital stay and the incidence of wound complications was not different between the two groups.

Conclusion: Peri-articular intra-operative multimodal analgesia significantly reduces post-operative PCA requirement. Patient satisfaction was greater in the injection group.
