Abstract
AIMS The fundamental concept of open reduction and internal fixation (ORIF) of ankle fractures has not changed appreciably since the 1960s and, whilst widely used, is associated with complications including wound dehiscence and infection, prominent hardware and failure. Closed reduction and intramedullary fixation (CRIF) using a fibular nail, wires or screws is biomechanically stronger, requires minimal incisions, and has low-profile hardware. We hypothesised that fibular nailing in the elderly would have similar functional outcomes to standard fixation, with a reduced rate of wound and hardware problems. PATIENTS AND METHODS A total of 100 patients (25 men, 75 women) over the age of 65 years with unstable ankle fractures were randomised to undergo standard ORIF or fibular nailing (11 men and 39 women in the ORIF group, 14 men and 36 women in the fibular nail group). The mean age was 74 years (65 to 93) and all patients had at least one medical comorbidity. Complications, patient related outcome measures and cost-effectiveness were assessed over 12 months. RESULTS Significantly fewer wound infections occurred in the fibular nail group (p = 0.002). At one year, there was no evidence of difference in mean functional scores (Olerud and Molander Scores 63; 30 to 85, versus 61; 10 to 35, p = 0.61) or scar satisfaction. The overall cost of treatment in the fibular nail group was £91 less than in the ORIF group despite the higher initial cost of the implant. CONCLUSION We conclude that the fibular nail allows accurate reduction and secure fixation of ankle fractures, with a significantly lower rate of soft-tissue complications, and is more cost-effective than ORIF.

Abstract
PURPOSE Stable fixation of distal humerus fracture fragments is necessary for adequate healing and maintenance of reduction. The purpose of this study was to measure the reliability and accuracy of interpretation of postoperative radiographs to predict which implants will loosen or break after operative treatment of bicolumnar distal humerus fractures. We also addressed agreement among surgeons regarding which fracture fixation will loosen or break and the influence of years in independent practice, location of practice, and so forth. METHODS A total of 232 orthopedic residents and surgeons from around the world evaluated 24 anteroposterior and lateral radiographs of distal humerus fractures on a Web-based platform to predict which implants would loosen or break. Agreement among observers was measured using the multi-rater kappa measure. RESULTS The sensitivity of prediction of failure of fixation of distal humerus fracture on radiographs was 63%, specificity was 53%, positive predictive value was 36%, the negative predictive value was 78%, and accuracy was 56%. There was fair interobserver agreement (κ = 0.27) regarding predictions of failure of fixation of distal humerus fracture on radiographs. Interobserver variability did not change when assessed for the various subgroups. CONCLUSIONS When experienced and skilled surgeons perform fixation of type C distal humerus fracture, the immediate postoperative radiograph is not predictive of fixation failure. Reoperation based on the probability of failure might not be advisable. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
The purpose of this study was to determine the effectiveness of increasing progesterone (P4) concentrations during early pregnancy, by supplementing a low dose of Regu-Mate® (Intervet, Millsboro, DE, USA) on Days 3, 4, and 5, post-ovulation to AI mares. Sixty-three AI-bred mares were randomly allocated to 1 of 2 treatment groups. All mares underwent ovulation induction using 1.5 mg mL–1 of deslorelin acetate (IM) following observation of ≥30-mm follicles and were inseminated with either fresh (n = 57) or cooled (n = 6) semen from fertile stallions approximately 24 h later. Ovulation was verified via ultrasonography in all mares. Mares allocated to the treatment group (n = 29) received altrenogest (Regu-Mate®) orally at a rate of 15 mg per day on Days 3, 4, and 5 following ovulation (d = 0), whereas control mares (n = 34) received no treatment. Blood samples were collected from all mares from Day 0 (ovulation) through Day 6 post-ovulation via jugular venipuncture. Pregnancies were determined via ultrasonography at 18 days post-ovulation. The pregnancy rate for untreated mares (18/34, 53%) was not different (P > 0.05) from altrenogest-treated mares (13/29, 45%). There was no difference (P > 0.50) in pregnancy rates when mares were AI bred 1 (19/39, 49%) or 2 (10/20, 50%) days from ovulation. The mean plasma P4 concentration on Day 5 was higher (P < 0.06) for pregnant control mares (4.75 ± 0.59 ng mL–1) compared with open control mares (3.50 ± 0.25 ng mL–1). There was a greater increase (P < 0.02) in plasma P4 concentrations (Day 5 – Day 1 concentration) in untreated pregnant mares (3.87 ± 0.56 ng mL–1) compared with untreated open mares (2.38 ± 0.22 ng mL–1). In conclusion, it was determined that altrenogest supplementation from Day 3 to 5 post-ovulation was ineffective in improving pregnancy rates. However, it is unknown if this was the result of the dose used or the length of supplementation. Additionally, the timing of altrenogest coincided with a significant increase in P4 in pregnant mares compared with open mares, indicating that the timing may be correct or there was action of an unknown embryonic luteotropin(s), which would describe the differences between P4 concentrations in pregnant versus open mares.

Abstract
Techniques for fixation of fractures of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce the incidence of complications. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Various different configurations of locking screw were assessed over the study period as experience was gained with the device. Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). Initial locking screw constructs rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable. Overall, seven patients had loss of fixation of the fracture and there were five post-operative wound infections related to the distal fibula. This lead to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw. In 21 patients treated with this technique there have been no significant complications and only one superficial wound infection. Good fracture reduction was achieved in all of these patients. The mean physical component Short-Form 12, Olerud and Molander score, and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. There have been no cases of fibular nonunion. Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture.

Abstract
The Galbeta1-3GalNAcalpha (TF antigen)-binding lectin (ABL) from the common edible mushroom (Agaricus bisporus) has a potent anti-proliferative effect without any apparent cytotoxicity. This unusual combination of properties prompted investigation of its mechanism of action. In contrast to soluble lectin, agarose-immobilized, and hence noninternalizable ABL had no effect on proliferation of HT29 colon cancer cells. Electron microscopy of HT29 cells incubated with fluorescein- and gold-conjugated ABL showed internalization of the lectin into endocytotic vesicles and multivesicular bodies. Confocal microscopy showed perinuclear accumulation of fluorescein isothiocyanate-conjugated lectin, which also inhibits HT29 cell proliferation, raising the possibility that the lectin might interfere with nuclear pore function. Transport of heat shock protein 70 into the nucleus in response to heat shock was blocked by preincubation of HT29 cells for 6 h with 40 micrograms/ml ABL. In digitonin-permeabilized cells, nuclear uptake of bovine albumin conjugated to a nuclear localization sequence (NLS)-containing peptide was also inhibited by a 15-min preincubation with 40-100 micrograms/ml ABL. In contrast, serum-stimulated nuclear translocation of mitogen-activated protein kinase, which is NLS-independent, was not affected by pretreatment of cells with the lectin. These results suggest that the anti-proliferative effect of ABL is likely to be a consequence of the lectin trafficking to the nuclear periphery, where it blocks NLS-dependent protein uptake into the nucleus.
