Intramuscular injections of botulinum neuro toxin A (BoNT-A) have been a cornerstone in the treatment of spasticity for the last two decades. In India, the treatment is now offered to children with spastic cerebral palsy (CP). However, despite its use, the evidence for its functional effects is limited and inconclusive. The objective of this study is to determine whether BoNT-A makes walking easier in children with CP. We hypothesize that injections with BoNT-A will not reduce energy cost during walking, improve walking capacity, reduce pain or improve self-perceived performance and satisfaction.

Between the period of 2012 and 2014, 35 children with spastic CP less than 10 years of age were included. The patients were classified according to their gross motor function classification system (GMFCS) and their pre-and post-injection gait analysis were performed. Spasticity assessed by Modified Ashworth Score [MAS]. Trained parents were utilised for the post injection physiotherapy as these children will be more complaint to them. GMFCS and MAS scoring done every three months till one year follow up.

Therapeutically, effect was found in 90% of the patients, an average duration of the medical effect was 6–12 months. The improvement in GMFC functional score in serial measurements was seen in these patients though some deterioration in spasticity scores at one year. Despite mild recurrence in spasticity, majority maintained independent (42%) or assisted ambulation (48%) at one year. No major side effects occurred. Botox may prove a useful adjuvant in conservative management of the spasticity of cerebral palsy. Apart from being very cost effective in these financially deprived populations, successful management with these injections may allow delay of surgical intervention until the child is older and at less risk of possible complications, including the need for repeated surgical procedures.

Introduction

The treatment of chronic osteomyelitis involves a debridement of affected non-viable tissue and the use of antibiotics. Where surgery leaves a cavity, dead space management is practised with antibiotic impregnated cement. These depots of local antibiotics are variable in elution properties and need removal. We review the use of bioabsorbable synthetic calcium sulphate as a carrier of gentamicin and as an adjunct in treating intramedullary osteomyelitis.

Methods

A retrospective review of cases treated consecutively from 2006 to 2010 was undertaken. Variables recorded included aetiology, previous interventions, diagnostic criteria, radiological features, serology and microbiology. The Cierney-Mader system was used to classify. Treatment involved removal of implants (if any), intramedullary debridement and local resection (if needed), lavage and instillation of the gentamicin carrier, supplemented with systemic antibiotics. Follow-up involved a survival analysis to time to recurrence, clinical and functional assessment (AOFAS-Ankle/IOWA knee/Oxford Hip) and general health outcome (SF36).

Where surgery leaves a cavity, dead space management is practised with antibiotic impregnated cement. These depots of local antibiotics are variable in elution properties and need removal. We review the use of bioabsorbable synthetic calcium sulphate as a carrier of gentamicin and as an adjunct in treating intramedullary osteomyelitis.

A retrospective review of cases treated consecutively from 2006 to 2010 in the Royal Liverpool University Hospital was undertaken. Variables recorded included aetiology, previous interventions, diagnostic criteria, radiological features, serology and microbiology. The Cierney-Mader system was used to classify. Treatment involved removal of implants (if any), intramedullary debridement and local resection (if needed), lavage and instillation of the gentamicin carrier, supplemented with systemic antibiotics. Follow-up involved a survival analysis to time to recurrence, clinical and functional assessment (AOFAS-Ankle/IOWA knee/Oxford Hip) and general health outcome (SF36).

There were 31 patients (22 male, 9 female). The mean age was 47 years (20-67). Twenty-five cases were post-surgery (6 open fractures) and 6 were haematogenous in origin. The median duration of osteomyelitis was 1.6yrs. The bones affected were 42% femur, 45% tibia, 3% radius and 10% humerus. 11 cases had diffuse as well as intramedullary involvement. 9 cases underwent segment resection and bone transport. We identified Staphylococcus Aureus in 16 and Coagulase Negative Staphylococcus in 6 cases. The median follow-up was 1.7 years (0.5-5.6). The median scores attained were: AOFAS-78, DASH-32, IOWA-71, Oxford-32. There were two recurrences.

Dead space management of intramedullary infections is difficult. We describe a method for delivery of local antibiotics and provide early evidence to its efficacy. The treatment success to date is 93%.

Bioabsorbable carriers of antibiotics are efficacious adjuncts to surgical treatment of intramedullary osteomyelitis.

Background: Knee stiffness from peri-articular fractures, arthroplasty or limb lengthening surgery, if intractable after an extensive programme of physiotherapy, may be resolved by quadricepsplasty. We describe the recovery of knee function in a cohort of 12 patients who underwent a Judet quadricepsplasty for loss of knee flexion.

Material and Methods: 12 adult patients underwent a Judet quadricepsplasty for recovery of knee flexion range. The causes of stiffness were trauma, arthroplasty, infection and limb lengthening surgery. A protocol of continuous passive knee movement under epidural analgesia was maintained after surgery. Continuous passive motion was continued at home for a further 4–6 weeks together with regular out-patient physiotherapy attendances. Outcome measures were range of movement, extensor lag, a modified WOMAC score for physical function, KINCOM data (with the contralateral limb as control), SF-36 and complications of surgery.

Results: There were 11 male patients and 1 female. The mean age was 30 years (20–71). The median period of follow-up was 3 years (0.8–7 years). The difference between pre-operative and final knee motion ranges was statistically significant (p=0.0048). The medians for flexion before surgery was 41 degrees (SD=18; at surgery 110 degrees (SD =15); final follow-up 105 degrees (SD=20). Extensor lag after surgery was 27.5 degrees (SD18) reducing 3.5 degrees (SD=3.5) finally. KINCOM data against a contralateral control showed a highly significant difference (p< 0.001) in quads strength. The medians for the WOMAC score was 38; PCS of the SF36 34.7 (SD13) and the MCS 53.7 (SD 13). Wound complications occurred in 7 patients and three needed further surgery.

Conclusion: Improvement in knee flexion after a Judet quadricepsplasty is maintained at one year. Extensor lag is common after the procedure but recovers. Most patients found the improvement beneficial but objective measures of knee function showed a return to normal had not been achieved.
