A patient in his thirties developed synovitis with grade 4 chondrolysis and a stiff knee with a fixed flexion deformity between three and six years following PLC and PCL reconstruction using LARS (Ligament Augmentation and Reconstruction System, Corin). There was histologic evidence of foreign body reaction, the knee was painful, swollen and stiff.

We did not use any further LARS ligaments for soft tissue reconstructions of the kneein our practice. We commenced a recall programme for all 83 patients patients who underwent a soft tissue knee reconstruction using LARS. Of those contacted, 41 replied (49%) and 16 patients had symptoms (19%) and were investigated further with XRay, MRI and arthroscopy as indicated.

We discovered a total of five patients had histologically proven synovitis with foreign body reactions (6%), three of whom had life-changing symptomatic pain, swelling and stiffness with degenerate changes (3.6%). These patients had undergone various reconstructions, including a) PLC only, b) ACL and PCL, c) PCL and PLC and d) ACL, PCL and PLC. A further single case of massive bone cyst formation was noted, following PCL reconstruction using LARS (1.2%).

The management of patients with displaced intra-capsular hip fractures is usually a hip hemiarthoplasty procedure. NICE guideline 124 published in 2011 suggested that Total Hip Replacement (THR) surgery should be considered in a sub group of patients with no cognitive impairment, who walk independently and are medically fit for a major surgical procedure.

The Royal Devon and Exeter Hospital manages approximately 550 patients every year who have sustained a fracture of neck of femur, of which approximately 90 patients fit the above criteria. Prior to the guideline less than 20% of this sub-group were treated with a THR whereas after the guideline over 50% of patients were treated with THR, performed by sub-specialist Hip surgeons.

This practice is financially viable; there is no apparent difference in the overall cost of treating patients with THR. The effect of adoption of the NICE guideline was examined using 100 % complete data from 12 month post operative follow up. Only the Hemi-arthroplasty patients were significantly less likely to have stepped down a rung of independent living. Both THR and Hemi-arthroplasty patients were significantly less likely to have stepped down a rung of walking ability, but there was no significant difference between THR and Hemi-arthroplasty groups. Revision rates remained negligible.

The management of patients with displaced intra-capsular hip fractures is usually a hip hemiarthoplasty procedure. NICE guideline 124 published in 2011 suggested that Total Hip Replacement (THR) surgery should be considered in a sub group of patients with no cognitive impairment, who walk independently and are medically fit for a major surgical procedure.

The Royal Devon and Exeter Hospital manages approximately 600 patients every year who have sustained a fracture of neck of femur, of which approximately 90 patients fit the above criteria. Prior to the guideline less than 20% of this sub-group were treated with a THR whereas after the guideline over 50% of patients were treated with THR, performed by sub-specialist Hip surgeons. This change was achieved by active leadership, incorporation of ‘Firebreak’ lists, looking for cases, flexible use of theatre time and operating lists and the nomination of an individual senior doctor who was tasked with a mission to improve practice.

This practice is financially viable; the Trust makes over £1000 per THR for fracture. Complete outcome data at 120 days show significantly fewer patients stepping down a rung in terms of both independent living and independent walking.

We report experience of 207 consecutive metal on metal hip resurfacings in 179 patients, implanted by one surgeon since January 2002. The mean age at operation was 56 years (35 – 78 years) and follow-up ranged from 12 to 84 months (mean 39 months). The gender mix was 2:1 M: F. The Birmingham Hip Resurfacing was implanted in the first 155 cases with a switch to Finsbury Adept Hip Resurfacing for the remaining 52 cases.

Data was obtained on all but one patient. There were four unrelated deaths (1.9%). No primary infections and no femoral neck fractures were encountered. One secondary infection at five years was salvaged by surgery and antibiotic treatment (0.5%). One male suffered a pertrochanteric fracture as a result of significant violence 15 months after operation (0.5%). Dislocation in five cases was the commonest complication encountered (2.4%). One of these cases developed recurrent dislocation and underwent early revision to a constrained total hip replacement (0.5%). This was the only failure in the series and no further revisions are pending.

Our survivorship results compare very favourably with outcomes reported from centres of excellence and far exceed the survivorship estimates published by the National Joint Registry.

Failure of fracture healing is a significant problem, resulting in considerable morbidity and financial costs to the NHS. It is also a major complication of ballistic injuries.

We reviewed our experience in the management of non-union by revision of fracture fixation and use of Bone Morphogenic Protein at Ministry of Defence Hospital Unit Frimley Park. Bone Morphogenic Proteins have been identified as promoting osteogenesis and have been used to stimulate bone growth in fracture revision surgery and spinal surgery. BMP’s are a subgroup of the TGF-β family and consist of at least 20 different subtypes of which BMP 2 and BMP 7 are commercially available. Current preparations include a solution for application to a gel matrix and as a powder for reconstitution to a paste for implantation to the fracture site. Costs per graft are in the region of £2,000.

BMPs have been used at Frimley Park since 2005 in the management of 12 patients with established non-union. These included fractures of 4 femurs, 5 humerai, 2 clavicles and 1 metatarsal. Early results are encouraging and support continued use of BMP’s in fracture revision surgery for established non-union.

Non-union remains a difficult problem and even with this treatment there was a significant failure rate, often associated with failure of fixation.
