Introduction

Computer hexapod assisted orthopaedic surgery (CHAOS) has previously been shown to provide a predictable and safe method for correcting multiplanar femoral deformity. We report the outcomes of tibial deformity correction using CHAOS, as well as a new cohort of femoral CHAOS procedures.

Aims

Computer hexapod assisted orthopaedic surgery (CHAOS), is a method to achieve the intra-operative correction of long bone deformities using a hexapod external fixator before definitive internal fixation with minimally invasive stabilisation techniques.

The aims of this study were to determine the reliability of this method in a consecutive case series of patients undergoing femoral deformity correction, with a minimum six-month follow-up, to assess the complications and to define the ideal group of patients for whom this treatment is appropriate.

Percutaneous grafting of non-union using bone marrow concentrates has shown promising results, we present our experience and outcomes following the use of microdrilling and marrowstim in long bone non-unions.

We retrospectively reviewed all patients undergoing a marrowstim procedure for non-union in 2011–12. Casenotes and radiographs were reviewed for all. Details of injury, previous surgery and non-union interventions together with additional procedures performed after marrowstim were recorded for all patients. The time to clinical and radiological union were noted.

We identified 32 patients, in sixteen the tibia was involved in 15 the femur and in one the humerus. Ten of the 32 had undergone intervention for non-union prior to marrowstim including 4 exchange nailings, 2 nail dynamisations, 3 caption graftings, 2 compression in circular frame and 1 revision of internal fixation. Three underwent adjunctive procedures at the time of marroswstim. In 18 further procedures were required following marrowstim. In 4 this involved frame adjustment, 5 underwent exchange nailing, 4 revision internal fixation, 2 additional marrowstim, 2 autologous bone grafting and 3 a course of exogen treatment.

In total 27 achieved radiological and clinical union at a mean of 9.6 months, of these ten achieved union without requiring additional intervention following marrowstim, at a mean of 5.4 months. There were no complications relating to marrowstim harvest or application.

Marrowstim appears to be a safe and relatively cheap addition to the armamentarium for treatment of non-union. However many patients require further procedures in addition to marrowstim to achieve union. Furthermore given the range of procedures this cohort of patients have undergone before and after marrowstim intervention it is difficult to draw conclusions regarding it efficacy.

Total hip replacement (THR) is NICE recommended for a group of patients with neck of femur fracture (NOF) and guidance published in 2011. In our institution a Hip Fracture Program was established at this time to improve patient care.

An audit of the Hip Fracture Program, appropriateness of THR and management following THR was undertaken and compared to NICE standards, set at 100%, and National Hip Fracture Database (NHFD) results

The case-notes for 53 patients (38 female, 15 male) undergoing THR for NOF between 2011 and 2013 were reviewed: median age 70 yrs (34–87), follow-up 28 months (3–57).

All patients were initiated on a Hip Fracture Program. 92% were eligible for THR according to NICE guidance. Pre-operative pain management (67%), hourly assessment of pain in ED (4%), surgery with 48 hours (32%), pre-operative orthogeriatric review (58%) and intra-operative nerve block (38%) are areas for development, but most results are comparable to NHFD. Post-operative care is satisfactory with daily mobilisation (87%) and post-operative pain management (100%). No post-operative dislocation or infection was recorded. There was one case of post-operative DVT.

This study highlights areas for improvement in hip fracture management and emphasises the benefits in implementing a Hip Fracture Program in this vulnerable patient population.

We would like to present this case series of 10 adolescent patients with displaced, closed diaphyseal tibial fractures managed using the Taylor Spatial Frame.

Management options for these injuries include non-operative treatment, antegrade nailing, flexible nailing systems, plating and external circular fixation. External circular fixation allows anatomical reduction avoiding potential complications such as growth arrest associated with antegrade nailing and retained metal work with plating. Flexible nailing system and cast immobilisation are unreliable for precise anatomical reduction. With limited evidence as to the extent of post-traumatic deformity that is acceptable, combined with the limited remodeling potential that this patient group possess, the precision of percutaneous fixation with the Taylor Spatial Frame system has clear advantages.

This is a retrospective analysis of 10 adolescent patients with a mean age of 14.5 years (range 13 to 16 years). Data collected includes fracture configuration, deformity both pre and post operatively compared to post frame removal, length of time in frame and complications. The data was gathered using the patient case notes and the Picture Archiving and Communications System. The mean time in frame was 15.5 weeks (range 11 to 22 weeks). One non-union in a cigarette smoker was successfully managed with a second Taylor Spatial Frame episode.

Our conclusion was that with careful patient selection the Taylor Spatial Frame allows successful treatment of closed tibial fractures in adolescents, avoiding complications such as growth arrest and post-traumatic deformity as well as avoiding retained metalwork.

Optimal utilisation of operating theatres has a significant impact on the ability of an institution to deliver productive, value for money surgical services. With the recent introduction of the national ‘Productive Theatres’ programme and in the current economic climate it is receiving increasing attention. In addition, it improves patient satisfaction and outcomes, reduces adverse events and has positive influences on staff morale. The aim of this study was to highlight factors influencing trauma theatre utilisation in general, whilst also addressing any problems identified with a view to improving trauma services locally. We conducted a prospective analysis of activity in the trauma theatre at our institution over 1 month. Direct observation was performed by a single independent observer. In the absence of any published guidelines, all theatre lists were assessed against pre-determined standards for each component of the theatre pathway. Overall end utilisation (combined time utilised for anaesthesia and surgery) was found to be low at 65%. A number of factors were found to contribute to inefficiencies including delay in sending for patients (mean 42mins, range 0-105), prolonged patient transit times to theatre (mean 22% of all sessions), late starts to lists (mean 43 mins, range 15-105 mins) waiting for x-ray availability (mean 21mins, range 10-45) and knock on delay from previous lists. Surgeons and anaesthetists were found to be, overall, arriving on time or early for all lists. Strategies for maximising trauma theatre productivity are essential. This study has identified common issues, of potential benefit to numerous institutions when planning trauma services.
