In 2010, we published results of Ponseti versus primary posteromedial release (PMR) for congenital talipes equinovarus (CTEV) in 51 prospective patients. This study reports outcomes at a median of 15 years from original treatment.

We followed 51 patients at a median of 15 years (range 13–17 years) following treatment of CTEV with either Ponseti method (25 patients; 38 feet) or PMR (26 patients; 42 feet). Thirty-eight patientsd were contacted and 33 participated in clinical review (65%), comprising patient reported outcomes, clinical examination, 3-D gait analysis and plantar pressures.

Sixteen of 38 Ponseti treated feet (42%) and 20 of 42 PMR treated feet (48%) had undergone further surgery. The PMR treated feet were more likely to have osteotomies and intra- articular surgeries (16 vs 5 feet, p<0.05). Of the 33 patients reviewed with multimodal assessment, the Ponseti group demonstrated better scores on the Dimeglio (5.8 vs 7.0, p<0.05), the Disease Specific Instrument (80 vs 65.6, p<0.05), the Functional Disability Inventory (1.1 vs 5.0, p<0.05) and the AAOS Foot & Ankle Questionnaire (52.2 vs. 46.6, p < 0.05), as well as improved total sagittal ankle range of motion in gait, ankle plantarflexion range at toe off and calf power generation. The primary PMR group displayed higher lateral midfoot and forefoot pressures.

Whilst numbers of repeat surgical interventions following Ponseti treatment and primary PMR were similar, the PMR treated feet had greater numbers of osteotomies and intra-articular surgeries. Outcomes were improved at a median of 15 years for functional data for the Ponseti method versus PMR, with advantages seen in the Ponseti group over several domains. This study provides the most comprehensive evaluation of outcomes close to skeletal maturity in prospective cohorts, reinforcing the Ponseti Method as the initial treatment of choice for idiopathic clubfeet

Cerebral palsy (CP) is a neural condition that impacts and impairs the musculoskeletal system. Skeletal muscles, particularly in the lower limb, have previously been shown to be significantly reduced in volume in CP compared to typical controls. Muscle volume is a gross measure, however, and does not capture shape characteristics which—if quantified—could offer a robust and novel assessment of how this condition impacts skeletal muscle form and function in CP. In this study, we used mathematical shape modelling to quantify not just size, but also the shape, of soleus muscles in CP and typically developing (TD) cohorts to explore this question.

Shape modelling is a mathematical technique used previously for bones, organs, and tumours. We obtained segmented muscle data from prior MRI studies in CP. We generated shape models of CP and TD cohorts and used our shape models to assess similarities and differences between the cohorts, and we statistically analysed shape differences.

The shape models revealed similar principal components (PCs), i.e. the defining mathematical features of each shape, yet showed greater shape variability within the CP cohort. The model revealed a distinct feature (a superior –> inferior shift of the broad central region), indicating the model could identify muscular features that were not apparent with direct observation. Two PCs dominated the differences between CP and TD cohorts: size and aspect ratio (thinness) of the muscle.

The distinct appearance characteristic in the CP model correspond to specific muscle impairments in CP to be discussed further. Overall, children with CP had smaller muscles that also tended to be long, thin, and narrow. Shape modelling captures shape features quantitatively, which indicate the ways that muscles are being impacted in CP. In the future, we hope to tailor this technique toward informing diagnosis and treatments in CP.

We report our retrospective multicentre experience of managing periprosthetic knee fractures using locking plates, cemented nails and distal femoral prosthesis. The Aim of this study is to analyze the practicality of management of these injuries using modern methods of fixation or salvation. 62 patients presented to 3 centres between 2003 and 2010. After implementation of inclusion criteria, clinical, radiological and functional outcomes were evaluated in 54 patients, with a minimum follow-up of 6 months. 34 patients were treated with locking plates (10 males, 24 female; mean age 76), 16 with cemented/locking nails (4 males, 12 females; mean age 84.5), and 4 with distal femoral replacement prosthesis (2 males, 2 females; mean age 79).

Locking plates which were used with a minimally invasive pattern produced the best outcomes in our study. A statistical significance of p value of less than 0.01 was found in union time between patients operated on with an open technique (6.69±2.69 months) and those operated on with a minimally invasive technique (3.6±0.91 months). Nailing with augmented cement is a useful technique in patients who are not suitable for challenging surgery & rehabilitation programmes. There was a significant difference in mean time to functional weight bearing (p< 0.01) between the plate group (4.79±2.6 months) and the nail group (2.63±0.5 months). Post-operative range of motion was also better for nails (106.36±14.33^O flexion) compared to plates (93.24±26.8^O), a result that approached significance (p=0.065). We recommend minimal invasive plating in uncompromised physiological conditions, as an ideal method of fracture fixation in view of statistically significant union rates. Cemented nailing is recommended in patients where early rehabilitation is essential. Distal Femoral prosthesis replacement is a useful salvage method.
