  • Short- and long-term results following standing fracture repair in 34 horses
    Equine veterinary journal, 2012
    Co-Authors: R. J. Payne, Paul Compston
    Abstract:

    Standing fracture repair in the horse is a recently described surgical procedure and currently there are few follow-up data. This case series contains 2 novel aspects in the standing horse: repair of incomplete sagittal fractures of the proximal phalanx and medial condylar repair from a lateral aspect. To describe outcome in a case series of horses that had lower limb fractures repaired under standing sedation at Rossdales Equine Hospital. Case records for all horses that had a fracture surgically repaired, by one surgeon at Rossdales Equine Hospital, under standing sedation and local anaesthesia up until June 2011, were retrieved. Hospital records, owner/trainer telephone questionnaire and the Racing Post website were used to evaluate follow-up. Thirty-four horses satisfied the inclusion criteria. Fracture sites included the proximal phalanx (incomplete sagittal fracture, n = 14); the Third metacarpal Bone (lateral condyle, n = 12, and medial condyle, n = 7); and the Third Metatarsal Bone (lateral condyle, n = 1). One horse required euthanasia due to caecal rupture 10 days post operatively. Twenty horses (66.7% of those with available follow-up) have returned to racing. Where available, mean time from operation to return to racing was 226 days (range 143-433 days). Standing fracture repair produced similar results to fracture repair under general anaesthesia in terms of both the number of horses that returned to racing and the time between surgery and race. Repair of lower limb fracture in the horse under standing sedation is a procedure that has the potential for tangible benefits, including avoidance of the inherent risks of general anaesthesia. The preliminary findings in this series of horses are encouraging and informative when discussing options available prior to fracture repair. © 2012 EVJ Ltd.

  • quantitative evaluation of subchondral Bone injury of the plantaro lateral condyles of the Third Metatarsal Bone in thoroughbred horses identified using nuclear scintigraphy 48 cases
    Equine Veterinary Journal, 2010
    Co-Authors: R. A. Parker, B. M. Bladon, Tim D.h. Parkin, Barny Fraser
    Abstract:

    Summary Reasons for performing study: Increased radio-isotope uptake (IRU) in the subchondral Bone of the plantaro-lateral condyle of the Third metatarsus (MTIII) is a commonly reported scintigraphic finding and potential cause of lameness in UK Thoroughbred racehorses in training and has not been fully documented. Objectives: To characterise lameness attributable to IRU of the subchondral Bone of MTIII, compare the scintigraphic findings of these horses with a normal population and evaluate the use of scintigraphy as an indicator of prognosis. Hypothesis: IRU will be in significantly higher in horses with subchondral Bone injury and will be related to prognosis and future racing performance. Methods: Data were analysed from 48 horses in which subchondral Bone injury of the plantaro-lateral condyle of MTIII had been diagnosed using nuclear scintigraphy and that met the inclusion criteria. Data recorded included age, sex, trainer, racing discipline, lameness assessment, treatment regimes, radiographic and scintigraphic findings, response to diagnostic analgesia where performed and racing performance pre- and post diagnosis. Region of interest (ROI) counts were obtained for the plantar condyle and the mid diaphysis from the latero-medial view, the ratio calculated and then compared with a control group of clinically unaffected horses. Results: The mean condyle mid-diaphysis ROI ratio was significantly (P<0.001) higher in the affected population and with positively correlation (P = 0.024) with the level of lameness. The presence of radiographic findings had no significant effect on the ROI ratio. Conclusion: Subchondral Bone injury of the plantar lateral condyles of MTIII is a significant cause of lameness in UK Thoroughbred racehorses. Nuclear scintigraphy is a useful diagnostic imaging modality in the detection of affected horses but is a poor indicator of prognosis for the condition. Potential relevance: Better understanding of the clinical manifestations, diagnosis of and prognosis for subchondral Bone injury will benefit the Thoroughbred industry in the UK.

  • Autologous morsellised Bone grafting restores uncontained femoral Bone defects in knee arthroplasty: AN IN VIVO STUDY IN HORSES
    The Journal of bone and joint surgery. British volume, 2000
    Co-Authors: C. J. M. Van Loon, P W Stolk, M.c. De Waal Malefijt, P. Buma, Nico Verdonschot, A. M. Tromp, Rik Huiskes, A. Barneveld
    Abstract:

    The properties of impacted morsellised Bone graft (MBG) in revision total knee arthroplasty (TKA) were studied in 12 horses. The left hind metatarsophalangeal joint was replaced by a human TKA. The horses were then randomly divided into graft and control groups. In the graft group, a unicondylar, lateral uncontained defect was created in the Third Metatarsal Bone and reconstructed using autologous MBG before cementing the TKA. In the control group, a cemented TKA was implanted without the Bone resection and grafting procedure. After four to eight months, the animals were killed and a biomechanical loading test was performed with a cyclic load equivalent to the horse’s body-weight to study mechanical stability. After removal of the prosthesis, the distal Third Metatarsal Bone was studied radiologically, histologically and by quantitative and micro CT. Biomechanical testing showed that the differences in deformation between the graft and the control condyles were not significant for either elastic or time-dependent deformations. The differences in Bone mineral density (BMD) between the graft and the control condyles were not significant. The BMD of the MBG was significantly lower than that in the other regions in the same limb. Micro CT showed a significant difference in the degree of anisotropy between the graft and host Bone, even although the structure of the area of the MBG had trabecular orientation in the direction of the axial load. Histological analysis revealed that all the grafts were revascularised and completely incorporated into a new trabecular structure with few or no remnants of graft. Our study provides a basis for the clinical application of this technique with MBG in revision TKA.
