Background. We compared pain relief after total hip arthroplasty using periarticular intraoperative injection along with single dose post operative injection of local anesthetic (THA) with the well-established practice of epidural infusion. Methods. 70 patients undergoing elective THA under combined spinal anaesthesia were randomly assigned to receive either (1) continuous epidural infusion (group B) or (2) infiltration around the hip joint with a mixture of 100 ml of bupivacaine (2 mg/ml) + 1ml ketorolac (30mg/ml) and 0.5ml epinephrine (1mg/ml) at the conclusion of surgery combined with one postoperative intraarticular injection of 20 ml. of Bupivacaine 0.5% + 1ml ketorolac (30mg/ml)+ 0.5 ml. epinephrine (1mg/ml) through an intraarticular catheter (group A). All patients received acetoaminophen 1gm 8 hourly for 72 hrs and injection ketoralac 30mg every 6 hourly IV(15mg if >65 yr 30mg if <65 yr). Breakthrough pain in any group (VAS >7) was treated by injection fentanyl 20 μg bolus at 10 min. interval till VAS reduced to < 4. If VAS 4–7 injection tramadol 50mg IV was given if VAS continued to be >4 after 15 min. then injection fentanyl 20 μg bolus was given at 10 min interval till VAS <4. Results. Narcotic consumption was significantly reduced in group A compared to group B (p=0.007). Pain levels at rest and during mobilization were similar in both groups during first 24 hrs but significantly reduced in group A after cessation of treatment. Interpretation. Wound infiltration combined with intraarticular injection of local Anaesthetics provides good pain relief for patients undergoing THA

Aims

The aim of this study was to compare the early postoperative mortality and morbidity in older patients with a fracture of the femoral neck, between those who underwent total hip arthroplasty (THA) and those who underwent hemiarthroplasty.

Aims

The aim of this study was to investigate the association between additional rehabilitation at the weekend, and in-hospital mortality and complications in patients with hip fracture who underwent surgery.

The CALEDonian Technique™, promoting enhanced recovery after surgery, is a multimodal multidisciplinary technique. This has demonstrated excellent analgesic control allowing early mobilisation and discharge following TKA, whilst maintaining patient safety. All patients follow a planned programme beginning with pre-operative out-patient education at the pre-assessment visit. An anaesthetic regimen consisting of pre-emptive analgesia is combined with a spinal/epidural with propofol sedation. Intra-articular local anaesthetic soft tissue wound infiltration by the surgeon under direct vision is supplemented by post-operative high volume intermittent boluses via an intra-articular catheter. Early active mobilisation is positively encouraged. A prospective audit of over 1000 patients demonstrated 35% of patients mobilised on day 0 and 95% by day 1, with rescue analgesia required in only 5% of cases. 79% of patients experienced no nausea or vomiting helping reduce length of stay from six to four postoperative days. A catheterisation rate of 7%, a DVT rate of 0.6% and a PE rate of 0.5% remained within or below previously published levels. Laboratory studies examining the performance of the epidural filter and injection technique used for the post-operative intra-articular injections demonstrated this to be robust and effective at preventing bacterial ingress. This in-vitro data is supported by clinical results demonstrating no increase in the deep infection rate of 0.7% since the implementation of the technique at our institution. We conclude that the CALEDonian Technique™ effectively and safely improves patient post-operative recovery following TKA

Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone.

Background. Randomized, controlled trials (RCTs) are generally accepted as the “gold standard” for the provision of the most unbiased measures of the efficacy of interventions but are often criticized for the lack of external validity. We assessed the external validity of a RCT examining the efficacy of local infiltration analgesia (LIA) compared with continuous epidural infusion after total knee arthroplasty (TKA). Methods. During a one-year period, all patients consecutively admitted for elective, unilateral, primary TKA were identified as potential participants. All underwent eligibility screening to determine who were eligible for participation in a randomized controlled trial. We investigated the distribution of preoperative characteristics and postoperative variables among excluded patients, non-consenters, and enrolled and randomized participants. Results. In all 157 patients were identified as potential participants. Only 49 patients (31%) were enrolled and randomized. A significant difference was found in both preoperative characteristics and clinical outcome variables. Non-participants were less healthy and needed more help from the home care service than did participants. Furthermore, they were hospitalized longer. Interpretation. Our findings demonstrate the importance of reporting the results of RCTs in a way that allows clinicians to judge to whom the results can reasonably be applied

Introduction. The purpose of this study was to compare the clinical outcomes and complications following bilateral simultaneous total knee arthroplasty in high body mass index (BMI) patients(>30kg/m. 2. ) to those of patients with a BMI<30 kg/m. 2. . Materials and Methods. Using data from an academic arthroplasty database and review of clinic charts we obtained health related quality of life (SF-12), and disease specific functional outcome scores (WOMAC or Oxford Knee Score). We also assessed length of hospital stay, ASA grade and transfusion requirements. Sixty six patients had a BMI<30 and 151 patients had a BMI>30. Results. Most cases were performed under combined spinal/epidural anaesthesia. We could find no appreciable difference in length of hospital stay, ASA grade or transfusion requirements between the two subgroups. Furthermore, were unable to detect any significant differences in post operative SF-12, WOMAC or Oxford Knee scores. There appeared to be no significant increase in the rate of medical complications between the two subgroups, and while there may have been a slight trend towards higher procedure related complications in the high BMI group, this did not reach statistical significance. Conclusions. In our study increased BMI appears to have no negative effects as regards functional outcomes, hospital stay or transfusion requirements for bilateral sequential knee arthroplasty. However there may be an increase in procedural/device related complications which could result in increased revision rates in these patients

Patients undergoing total knee arthroplasty (TKA) experience significant postoperative pain. This impedes early mobilization and delays hospital discharge. A prospective audit of 1081 patients undergoing primary TKA during 2008 was completed. All patients followed a programme including preoperative patient education, pre-emptive analgesia, spinal/epidural anaesthesia with propofol sedation, intra-articular soft tissue wound infiltration, postoperative high volume ropivacaine boluses with an intra-articular catheter and early mobilization. Primary outcome measure was length of stay. Secondary outcomes were verbal analogue pain scores on movement, time to mobilization, nausea and vomiting scores, urinary catheterization for retention, need for rescue analgesia, range of motion at discharge and six weeks postoperatively. The median day of discharge was postoperative day four. Median pain score on mobilization was three for first postoperative night, day one and two. 35% of patients ambulated on the day of surgery and 95% of patients within 24 hours. 79% patients experienced no nausea or vomiting. Catheterization rate was 6.9%. Rescue analgesia was required in 5% of cases. The median day of discharge was postoperative day four. Median range of motion was 85° on discharge and 93° at six weeks postoperatively. This comprehensive care plan provides satisfactory postoperative analgesia allowing early safe ambulation and discharge

Objectives. Juxtafacet cysts of the spine can cause radicular pain, neurological symptoms and are often associated with spinal degeneration. The mainstay of treatment of juxtafacet cysts is surgical resection with laminotomy and resection of the cyst. Other methods, including epidural steroid and facet injections are mostly temporarily effective. The aim of this study is the sufficient decompression with reduced traumatization and destabilization with the full-endoscopic interlaminar and transforaminal technique. Methods. 60 patients with unilateral, single-level juxtafacet cysts were included in this study. 30 Patients (group 1) were operated in full-endoscopic technique (22 interlaminar, 8 trans-/extraforaminal) and 30 Patients (group 2) with conventional microscopic-assisted technique. The full-endoscopic operation was performed with 6.9-mm endoscopes with 4.1-mm intra-endoscopic working canal. The follow-up was 18 months. 27 (91%) patients were followed. Additionally to general parameters validated scores were used. Results. No intraoperative complications occurred. 2 patient in group 1 and 4 patients in group 2 showed transient dysaesthesia. The mean operation time in group 1 was 32 minutes, in group 2 56 minutes. There was no measurable blood loss in group 1, and a mean blood loss of 85 ml in group 2. The follow-up showed satisfactory subjective results in 53 patients. There were no significant differences between the two groups or within group 1 between the transforaminal and interlaminar technique in the clinical results. Group 1 showed significant advantages in different clinical, technical and economical parameters. The maximum time in hospital for group 1 patients was 3 days and 6 days in group 2. No recurrence of the cyst was found in the follow up. Conclusion. The full-endoscopic operation of lumbar facet cysts with full-endoscopic technique is an alternative to the conventional microscopic-assisted procedure for sufficient decompression of juxtafacet cyst. It enables selective procedure with direct visualization, sufficient decompression and less traumatization of the access pathway and the spinal canal structures

Introduction. Tranexamic acid is an inhibitor of fibrinolysis that blocks the lysine-binding site of plasminogen to fibrin, and thereby decreases blood loss in patients undergoing surgery. Aims and objectives. A prospective, randomized, double-blind study was done on 100 patients undergoing primary cemented Unilateral Total Knee Arthroplasty to determine the effect of tranexamic acid on intra- and postoperative blood losses and on the transfusions requirements. Material and Methods. 100 patients undergoing unilateral cemented total knee Arthroplasty for osteoarthritis were enrolled for the study. All total knee replacement was done under combined spinal epidural anaesthesia with the use of tourniquet. 100 patients were randomized to tranexamic acid (15 mg/kg) given as a bolus intravenous injection or placebo (normal saline) given intravenously, 15 minutes before the release of tourniquiet. The blood loss (at removal of the drain 24 hours after the operation) and the number of blood transfusions required were recorded. The patients were screened for deep venous thrombosis with bilateral compression Ultrasonography using Colour Doppler imaging on the tenth postoperative day. The Hemoglobin level was measured preoperatively and on the 3rd postoperative day. The D-dimer levels were measured preoperatively and 24 hrs postoperatively. Results. Patients receiving tranexamic acid had a mean postoperative blood loss of 175 ml(range, 130–310ml) versus 330 ml (range, 210–460ml) (p value<0.05), and a total need for 3 blood transfusions versus 15. Only 3 out 50 patients in tranexamic acid group required blood transfusion whereas 12 out of 50 patients in the placebo group required transfusion. In the group receiving placebo the mean fall in hemoglobin was 2.1g/dl (range, 1.5–3.2) and in the group treated with tranexamic acid 1.3 g/dl (0.9–2) (p<0.05). At 24 hrs postoperatively, mean plasma D-dimer concentration in the Tranexamic group was half of that in the control group. No patient in either group had any evidence of deep vein thrombosis on bilateral compression Ultrasonography using Colour Doppler imaging done on the tenth postoperative day. Conclusion. Tranexamic acid 15 mg/kg given as a single bolus dose reduces blood loss, and transfusion requirements in unilateral primary cemented total kneearthroplasty without any increased risk of thrombus formation

Introduction. The peri-operative analgesic management of patients having either Total Knee Replacement (TKR) or Unicompartmental Knee Replacement (UKR) is an area that continues to have prominence, driven in part by the desire to reduce hospital stay, while maintaining high patient satisfaction. This is particularly relevant in the current climate of healthcare cost savings. We evaluated the role of “top up” intra-articular local anaesthetic injection after identifying that an appreciable number of patients in the unit suffered “breakthrough pain” on the first post-op day, when the effects of local analgesia are wearing off. Method. 43 patients, who were scheduled to have a cemented Oxford UKR, were prospectively recruited and randomised. All patients had the same initial anaesthetic regime of general anaesthesia, femoral nerve block and intra-operative intra-articular infiltration of the cocktail. All patients had a 16G multi-holed epidural catheter placed intra-articularly prior to wound closure. Patients had the same operative technique, post operative rehabilitation and rescue analgesia. An independent observer recorded post-operative pain scores using a visual analogue score (1–10) every 6 hours and any rescue analgesia that was required. On the morning after surgery, 22 patients, (Group I), received 20 mls of 0.5% bupivicaine through the catheter whilst 21 patients, (Group II), had 20 mls of normal saline by the same observer, (who was blinded to the contents of the solution being injected), after which the catheter was removed. Results. When comparing these two groups there was no statistical difference found in their pain scores on the day of operation. However, patients in Group I had a significantly better pain score initially post top up and then at 6 hours (2.4 (0–8) vs 5.7 (2–9), Mann-Whitney p<0.001). This cohort of patients required less rescue analgesia (22% vs 75%, Mann-Whitney p<0.001). In addition, Group I had statistically significant higher patient satisfaction outcome scores after the infiltration, (p<0.001), with 16 reporting very good satisfaction in comparison to 1 in Group II. There were no complications in either group. Discussion. Our study has shown that injection of local anaesthesia via an intra-articular catheter does reduce pain scores when compared to placebo. This implies that this technique may have a role in providing optimal pain relief after UKR

Introduction. Significant access morbidity with intercostal neuralgia and post-thoracotomy pain syndrome was reported in case that an anterior approach for spondylodesis of fractures of the thoracolumbar spine was used. We describe our experience with thoracoscopical fusion from anterior as a less invasive approach. Patients. Between 02/2007 and 09/2008 in a series of 32 patients (18 male; mean age 43, 17–74yrs) with fractures of the thoracolumbar spine (level Th11: n = 2, level Th12: n = 12, level L1: n = 18; fracture types: A3.1.1: n = 15, A3.2.1: n = 11, A3.3.1: n = 3, B2.1: n = 1 and B2.3: n = 2) thoracoscopical fracture stabilization was performed. A less invasive approach with three portals without an assistant was used facilitated by a new retractor system. In 16 patients fracture stabilization from anterior was supported by an additional spondylodesis using an dorsal approach. For reconstruction of the anterior column a VLIFT-system (n = 19), a Synex- (n = 11) or a Harms-Cage (n = 2) in combination with a MACS-TL (n = 16) or a Arcofix-system (n = 2) were used. Results. Thoracoscopical fusion from anterior was performed about 8 days after the injury (1–73 days), monosegmental in 11 and bisegmental in 21 out of 32 cases. The mean overall operating time was 201min (range 105–380min). The mean overall blood loss was 780ml, in 3/32 patients blood transfusions were required. In one patient epidural bleeding and in another a screw cut-out of the MACS system of the first lumbar vertebral body occurred intraoperatively. Revision surgery was necessary due to failure of the hardware (n = 2) or occurrence of hematothorax (n = 1). In the further follow up period no wound healing disorders, failure of the implants nor intercostal neuralgia were noted. Discussion. The endoscopic view is two-dimensional and may disorientate the less experienced surgeon, and thus, prolong operation time. However, the use of a retractor system allowed for bimanual operation increasing the depth perception, provided an optimal illuminated, and permanent and stable operation field, and was economic as an assistant was not required. Conclusion. The presented technique is a high demanding approach for anterior fusion of fractures of the thoracolumbar spine, however, with the potential to reduce the surgical access trauma to a minimum with an operation time comparable to open surgery. Patients might benefit from a shortened rehabilitation and a early reintegration into professional life

Aims

This study sought to determine the proportion of older adults with hip fractures captured by a multicentre prospective cohort, the World Hip Trauma Evaluation (WHiTE), whether there was evidence of selection bias during WHiTE recruitment, and the extent to which the WHiTE cohort is representative of the broader population of older adults with hip fractures.

Aims

The aim of this study was to investigate the association between the type of operation used to treat a trochanteric fracture of the hip and 30-day mortality.

Aims

In this randomized study, we aimed to compare quality of regenerate in monolateral versus circular frame fixation in 30 patients with infected nonunion of tibia.

We conducted a randomised controlled trial to compare external fixation of trochanteric fractures of the femur with the more costly option of the sliding hip screw. Patients in both groups were matched for age (mean 67 years, 50 to 100) and gender. We excluded all pathological fractures, patients presenting at more than one week, fractures with subtrochanteric extension or reverse obliquity, multiple fractures or any bone and joint disease interfering with rehabilitation. The interval between injury and operation, the duration of surgery, the amount of blood loss, the length of hospital stay and the cost of treatment were all significantly higher in the sliding hip screw group (p < 0.05). The time to union, range of movement, mean Harris hip scores and Western Ontario and McMaster University knee scores were comparable at six months. The number of patients showing shortening or malrotation was too small to show a significant difference between the groups. Pin-track infection occurred in 18 patients (60%) treated with external fixation, whereas there was a single case of wound infection (3.3%) in the sliding hip screw group.

Our aim was to determine the total blood loss associated with surgery for fracture of the hip and to identify risk factors for increased blood loss. We prospectively studied 546 patients with hip fracture. The total blood loss was calculated on the basis of the haemoglobin difference, the number of transfusions and the estimated blood volume. The hidden blood loss, in excess of that observed during surgery, varied from 547 ml (screws/ pins) to 1473 ml (intramedullary hip nail and screw) and was significantly associated with medical complications and increased hospital stay. The type of surgery, treatment with aspirin, intra-operative hypotension and gastro-intestinal bleeding or ulceration were all independent predictors of blood loss.

We conclude that total blood loss after surgery for hip fracture is much greater than that observed intra-operatively. Frequent post-operative measurements of haemoglobin are necessary to avoid anaemia.
