Current health economics forces the clinician to consider the cost of treatment. Currently in Fife Hospitals, all lower limb injuries likely to require operative treatment are admitted from the Accident and Emergency department on the day of injury. The aim of this investigation was to see if non-emergency trauma cases could be managed pre-operatively as outpatients to reduce costs.

We prospectively recorded all patients admitted with lower limb trauma excluding neck of femur fractures, requiring operative treatment over an eleven-week period. The senior author reviewed all patients and a clinical judgment was made as to whether the patient could have been safely managed as an outpatient pre-operatively.

61 patients met the inclusion criteria. Average age 41.8 (Range 8-66). The three most common fractures were 23(38%) ankle fractures, 15(25%) tibial fractures and 8(13%) femoral shaft fractures. 28(46%) fractures were deemed safe to have been managed preoperatively on an outpatient basis. 14/23(61%) ankle fractures were deemed safe to be discharged home. The average pre-operative stay was 1.38 nights (Range 1-4 nights).

By initiating a simple policy of allowing uncomplicated ankle fracture patients to wait at home and return on the morning of surgery it is possible to reduce inpatient occupancy by 64 nights per year in our department. At a cost of £518 per patient per night, this could result in a saving of around £33,000 in unnecessary overnight inpatient stays. In order to achieve this, clear clinical guidance for admitting doctors is necessary and further prospective research should be conducted into the risk/benefit of implementing this policy.

The risk of venous thrombo-embolism (VTE) is high in orthopaedics. Oral direct factor Xa inhibitors have been introduced to help reduce the incidence of VTE. To reduce post-operative bleeding antifibrinolytics are used. We aimed to ascertain the effect of two drugs on post-operative bleeding and transfusion requirements.

We prospectively recorded patient demographics, operative details, complications, transfusion incidence and VTE incidence in TKR patients. We also sent out a questionnaire to patients asking about wound bleeding and VTE. All patients were given 10mg Rivaroxaban 8 hours post operatively and then once a day for 14 days. Patients given tranexamic acid were given 500mg IV, 5 minutes prior to wound closure at the discretion of the surgeon. VTE was confirmed by Doppler or CTPA as Deep Vein Thrombus or Pulmonary Embolism. Minor bleed was categorised as dressing soakage or reported wound leakage, major bleed as haematoma requiring revision within 30 days.

509 patients underwent TKR: 200(39%) only received Rivaroxaban (Group 1), 296(58%) also received tranexamic acid (Group 2). 13(3%) of patients had no data available. 5 patients had a VTE: 4 (2%) Group 1, 1 (0.3%) Group 2 (P<0.05). 39 patients had a minor bleed: 17 (8.5%) Group 1, 22 (7.4%) Group 2 (P=0.5). 2 patients had major bleeds: 1 (0.5%) Group 1, 1 (0.33%) Group 2 (P=0.69). Blood transfusions 21: (10.5%)Group 1, 9 (3%) Group 2 (P<0.0001).

We have demonstrated a reduced requirement for blood transfusions in the tranexamic acid group. However our results whilst they show a trend towards decrease bleeding rates in both the minor and major bleeds are not significant, requiring larger studies looking at wound bleeding and leakage.

To assess the effectiveness of unilateral sublaminar and concave rib tethering with convex rib resection through the period of peak growth in lambs.

Morphometric growth data from 10 experimental Scottish Blackface sheep were compared to those from 5 control animals (no intervention) over 12 months.

Standardized AP and Lateral radiographs were taken before and at monthly intervals after scoliosis creation. The Cobb angle was measured in the coronal and sagittal planes. Rotational mal-alignment was assessed by axial CT 7 months post surgery.

In the supine position the control animals had no coronal plane deformity and a mean 5° lordosis (T4-T12). These figures did not alter with growth (doubling of body weight). Tethering (at age 5 weeks) produced an immediate scoliosis of 22±11° and a lordosis of 24±8° (means(sd). The degree of scoliosis was maintained over 7 months (at 20°) but lordosis increased (to 59±11°, p<0.01). There was an associated change in vertebral rotation. Surgery had no influence on rate of growth or animal development.

Two animals died from Clostridium associated enterocolitis. There were no deaths associated with the surgical intervention.

This ovine model gives a progressive spinal deformity in the sheep but primarily in the sagittal plane. This fact should be considered in studies designed to evaluate the effectiveness of surgical implants.
