  • Biomechanical and Histological Assessment of a Polyethylene Terephthalate Screw Retention Technology in an Ovine Metatarsal Fracture Model.
    Veterinary and comparative orthopaedics and traumatology : V.C.O.T, 2020
    Co-Authors: Jeremiah Easley, Christian Puttlitz, Cecily Broomfield, Alexander Jones, Ross Palmer, Kirk C Mcgilvray
    Abstract:

     Screw loosening in Fracture fixation poses a clinical risk which may lead to implant failure, particularly in poor bone quality. The objective of this study was to examine the effectiveness of a novel screw retention technology (SRT) for increased screw purchase in a large animal Metatarsal Fracture model.  This was a biomechanical, radiographic, and histological study utilizing an ovine Metatarsal Fracture model. Twenty-four sheep metatarsi underwent 3-mm ostectomies and were repaired with a nine-hole plate and 3.5-mm screws placed in oversized 3.5-mm holes to simulate worst case revision surgeries (i.e. no initial screw thread bone contact). Sheep were sacrificed at 3, 6 or 12 weeks (n = 6 each) post-operation. Post-sacrifice, each surgically implanted screw underwent either destructive mechanical testing or histomorphometric analyses.  Treated metatarsi showed improved screw retention and normal Fracture healing. Significant improvement in breakout strength and pullout strength of screws treated with the SRT were found as a function of healing time. Histologically, bone ingrowth at the screw interface was also shown to significantly increase with healing time. Improvements in Fracture healing, indicated by an increase in bone fraction and decrease in void space at the osteotomy, were also observed with healing time.  The results demonstrate the effectiveness of the SRT as a method for improved screw retention in a rescue-screw type scenario.

  • lactose intolerance associated with Fractures of weight bearing bones in finnish women aged 38 57 years
    Bone, 1997
    Co-Authors: R Honkanen, Heikki Kroger, E Alhava, P Turpeinen, Marjo Tuppurainen, Seppo Saarikoski
    Abstract:

    Lactose intolerance (LI) often results in decreased calcium intake. To test if long-term low intake of calcium affects bone strength, we examined Fracture risks related to LI in women aged 38–57 years. The 11,619 Finnish women aged 47–56 years who responded to the baseline postal inquiry of the Kuopio Osteoporosis Risk Factor and Prevention Study in 1989 formed the study population. In all, 896 women reported LI and 1299 women reported a Fracture in 1980–1989. Current intake of dairy calcium was lower in women with LI (570 mg/d) than in the other women (850 mg/d) (p < 0.0001). The Fracture risk in general was slightly elevated in women with LI compared with the other women, with an odds ratio (OR) (95% CI) of 1.33 (1.09–1.62). However, the Fractures at the three most common sites (wrist, ankle, and rib) were not related to LI. In contrast, Fractures at the tibia and Metatarsal were strongly related to LI with ORs of 3.31 (1.51–7.24) and 2.84 (1.47–5.50), respectively. The adjusted OR for nonankle lower body Fractures combined was 2.15 (1.53–3.04), whereas that for all upper body Fractures combined was 1.15 (0.88–1.54). The 10 women with LI and a tibial or Metatarsal Fracture showed a 19% lower femoral BMD than all the other women in the densitometry subsample of 3222 women (p < 0.001). Long-term premenopausal calcium deficiency differentially affects bones with weight-bearing nonankle bones being at the greates risk of suffering reduced strength.
