As per NICE guidance, one of the cornerstones of management of AKI is risk assessment. Aim of the audit is to identify the potential risk factors for postoperative AKI in hip fracture patients.

Various technical tips have been described on the placement of poller screws during intramedullary nailing however studies reporting outcomes are limited. Overall, there is no consistent conclusion about whether intramedullary nailing alone, or intramedullary nails augmented with poller screws is more advantageous. In a systematic review, we asked: (1) What is the proportion of non-unions with poller screw usage? (2) What is the proportion of malalignment, infection and secondary surgical procedures with poller screws usage?

We conducted a systematic review of multiple databases including Pubmed, EMBASE, and the Cochrane Library. Seventy-four records were identified, twelve met our inclusion criteria.

Twelve studies with a total of 348 participants and 353 fractures were included. Mean follow up time was 21.4 months and mean age of included patients was 40.1 year. Seven studies had heterogenous population of non-unions and/ or malunions in addition to acute fractures. Three studies included only acute fractures and two studies examined non unions only. Four of the twelve studies reported non unions with an overall outcome proportion of 4%. Six studies reported coronal malalignment with an overall outcome proportion of 6%. The secondary surgical procedures rate ranged from 2 – 40% with an overall outcome proportion of 8% and included grafting, revisions and any reported cases of removal of metal work.

When compared with existing literature our review suggests intramedullary nailing with poller screws has lower rates of non-unions and coronal malalignment than those reported in the literature for intramedullary nailing alone. Prospective randomized control trial is necessary to fully determine outcome benefits.

Open lower limb fractures are resource-intensive fractures, accounting for a significant proportion of the workload and cost of orthopaedic trauma units. A recent study has evaluated that the median cost of direct inpatient treatment of open lower-limb fractures in the National Health Service (NHS) is steep, at £19189 per patient. Healthcare providers are expected to be aware of the costs of treatments, although there is very limited dissemination of this information, neither on a national or local level. Older adults (>65 years old) are at an increased risk of the types of high-energy injuries that can result in open lower limb fractures. Generally, there remains a significant lack of literature surrounding the cost of open fracture management, especially in specific patient groups that are disproportionately affected by these fractures. This study has calculated the direct inpatient care costs of older adults with open lower limb fractures.

Open lower limb fractures in adult patients over 65 years old treated at Addenbrooke's Hospital of Cambridge University Hospitals NHS Trust were identified over the period of March 2014-March 2019. Isolated fractures of the femur, tibia and fibula over this time period were included. Direct inpatient care costs were calculated using information about the sustained fracture, operative time, implant(s) and theatre kit(s) used, the number of patient bed-days on the orthopaedic ward and critical care unit, and the number of hours of inpatient physiotherapy received. Direct inpatient care costs were compared with the income received by our centre for each of these cases, according to Healthcare Resource Group (HRG) cost codes. Our data was also compared with existing literature on Patient Level Costing (PLC) figures for open lower limb fractures.

We extracted data from 58 patients over the age of 65 years treated for open isolated lower limb fractures at Addenbrooke's Hospital, Cambridge University Hospitals NHS Trust, between March 2014 and March 2019. The median cost of inpatient care calculated in this study was £20,398 per patient, resulting in a financial loss to the hospital of £5113 per patient. When the results were disaggregated by sex, the median cost for an open lower limb fracture in a male patient was £20,886 compared to £19,304 in a female patient. Data were also disaggregated by the site of injury, which produced a median cost for an open femur fracture of £23,949, and £24,549 and £15,362 for open tibia and ankle fractures, respectively.

The absence of published primary literature and clinical audits on this topic continues to hinder the inclusion of cost-effectiveness as an important factor in clinical decision-making. This study provides valuable insight into the true cost of open lower limb fractures in a key patient population in a Major Trauma Centre in England and highlights the large losses incurred by hospitals in treating these cases. These results support the revision of the remuneration structures in the NHS for the treatment of elderly patients with these injuries.

Tourniquets have been used for many years during total knee arthroplasty (TKA). With a growing demand for TKA in recent years, tourniquet use has been surrounded by ongoing controversy due to many conflicting advantages and disadvantages of tourniquet use. Quantifying the case for or against tourniquet use in TKA, in terms of patient focused outcomes, is a priority. This meta-analysis analysed, the never before assessed, impact of tourniquet use during TKA on post-operative pain. We completed a systematic review and meta-analysis using PRISMA reporting guidelines to assess the impact of tourniquet use on patients post-TKA. Post-operative pain was the primary outcome. Secondary outcomes were post-operative range of motion (ROM) and length of stay (LOS). The initial search yielded 230 studies, of which 14 met the inclusion criteria. A post-operative increase in pain and reduction in ROM when using a tourniquet appeared significantly more likely when compared to no tourniquet use during TKA, yet with no overall difference in post-operative LOS. Subgroup meta-analysis demonstrated a trend that favoured the half-course tourniquet for reduced post-operative pain in patients when compared to full tourniquet use during TKA. This systematic review and meta-analysis concluded that the after-effects of tourniquet use in TKA patients and its impact on post-operative pain and ROM are indeed significant. We recommend further randomized controlled trials (RCTs) focusing on TKA patient outcomes of post-operative pain and ROM.

The treatment of massive chronic tears is problematic. The re-tear rate following surgery for extensive cuff tears remains high, and there is little consensus regarding optimum treatment. To investigate the outcome of a cohort of patients who had open repair of an extensive cuff tear using the Leeds Kuff patch as an augment. A retrospective cohort study of consecutive patients with a massive cuff tear who had surgery in our regional elective orthopaedic centre over a two year period from January 2015 to Dec 2016. All patients followed identical rehabilitation protocols, supervised by physiotherapists with an interest in the shoulder. Outcomes assessment was undertaken at a minimum of 12 months by a registrar or physiotherapist who was not part of the treating team. Pre-op data collection included; range of motion, pain score, Oxford shoulder score (OSS), assessment of muscle atrophy on MRI. Data collection was completed in 15 patients. The mean age was 62 yrs (56 – 75). The mean pre-op OSS was 22, improving to a mean of 43. The range of motion and pain score improved. There were no intra-operative complications. One patient required a second surgery for evacuation of a haematoma at 10 days post op. One patient had an obvious re-tear at 4 months. Open rotator cuff repair with synthetic Kuff patch augmentation for chronic degenerative tears appears worthwhile when assessed at 12 months and they continuous to improve even at 18 months. This treatment method may be a useful option for patients > 70 years old.

Introduction

Surgical gloves function as a mechanical barrier that reduces transmission of body fluids and pathogens from hospital personnel to patients and vice versa. The effectiveness of this barrier is dependent upon the integrity of the glove. Infectious agents have been shown to pass through unnoticed glove microperforations which have been correlated to the duration of wear. Varying factors may influence the integrity of the glove such as the material, duration of use, activities and fit. Studies have recommended changing gloves 90 minutes into a general surgical operation, however there are no known EBM recommendations in orthopaedic surgery.

Introduction

Tourniquets have been used for many years during total knee arthroplasty as a means of achieving a bloodless field for better visualization and cement-bond inter-digitation. Controversy has surrounded the necessity for a tourniquet in past years. There are many advantages and disadvantages to using a tourniquet, and one prominent disadvantage is a purported increase in post-operative pain and limitations in range of motion.

Introduction

The role of diathermy in orthopaedic surgical practice has increased since its introduction. It is widely used for underlying tissue dissection, cutting, and haemostasis. Previous studies have compared electrosurgical and scalpel incisions in terms of wound infection, wound-related pain, and blood loss. There are well documented hazards associated with diathermy use including burns injury, electrocution, hypoxic stress, inhalation of diathermy plume, and gene mutation. No single study to date has focused on the potential for diathermy tips to cause wound contamination and infection. We sought to identify whether diathermy tips could be possible sources of infection in orthopaedic procedures.

There are well documented hazards associated with diathermy use including burns injury, electrocution, hypoxic stress, inhalation of diathermy plume, and gene mutation. No single study to date has focused on the potential for diathermy tips to cause wound contamination and infection. We sought to identify whether diathermy tips could be possible sources of infection in orthopaedic procedures.

To determine the prevalence of bacterial contamination of diathermy tips during orthopaedic surgery and to assess any correlation with surgical site infections.

From July 2013 to September 2013, the diathermy tips from 86 consecutive orthopaedic procedures using diathermy were cultured using direct and enriched media. None of the diathermy tips were used for the skin incision. All patients underwent an orthopaedic procedure for a non-infected condition. For each procedure an unused control diathermy tip was placed on the instrument table at the beginning of the procedure and processed similarly. All patients were followed for any postoperative complications.

108 diathermy tips from 86 orthopaedic procedures were cultured. None of the tips cultured directly on blood agar demonstrated bacterial growth. Following enrichment culture, 6 (5.6%) of the procedure diathermy tips and 1 (0.92%) of the control tips demonstrated bacterial growth. Coagulase-negative staphylococci (83.3%) and proprionibacterium (16.7%) were cultured from the tips. 1 of the patients who had bacterial growth from the diathermy tip developed a superficial surgical site infection.

Surgical site infections contribute substantially to orthopaedic surgical morbidity and mortality each year. The prevention of these infections encompasses careful operative technique, preoperative antibiotics, and a number of important measures to minimize the risk of bacterial contamination posed by operative staff, the operating theatre environment, and the patient's endogenous skin flora. Identifying potential bacterial sources is an important component of surgery. The two bacteria cultured in our study (coagulase-negative staphylococci and proprionibacterium) are both well known major culprits in orthopaedic infections, responsible for up to 70% of early and late peri-prosthetic infections. Our study suggests diathermy tips and the tissue coagulated by its use may not be as sterile as previously thought. There may be benefit in changing the diathermy tips during orthopaedic procedures as they may represent a possible source of bacterial contamination.

Summary Statement

This project proves that Patellofemoral (PF) joint degeneration is not a contraindication to medial unicompartmental knee replacement.

Revision hip arthroplasty requires a comprehensive appreciation of abnormal bony anatomy. Advances in radiology and manufacturing technology have made three-dimensional representation of actual osseous anatomy obtainable. These models provide a visual and tactile reproduction of the bony abnormality in question.

Life size three dimensional models were manufactured from CT scans of two patients. The first had multiple previous hip arthroplasties and bilateral hip infections. There was a pelvic discontinuity on the right and a severe postero-superior deficiency on the left. The second patient had a first stage revision for infection and recurrent dislocations. Specific metal reduction protocols were used to reduce artefact. The dicom images were imported into Mimics, medical imaging processing software. The models were manufactured using the rapid prototyping process, Selective Laser Sintering (SLS).

The models allowed accurate templating using the actual prosthesis templates prior to surgery. Acetabular cup size, augment and buttress sizes, as well as cage dimensions were selected, adjusted and re-sterilised in advance. This reduced operative time, blood loss and improved surgical decision making. Screw trajectory simulation was also carried out on the models, thus reducing the chance of neurovascular injury.

With 3D printing technology, complex pelvic deformities can be better evaluated and can be treated with improved precision. The life size models allow accurate surgical simulation, thus improving anatomical appreciation and pre-operative planning. The accuracy and cost-effectiveness of the technique were impressive and its use should prove invaluable as a tool to aid clinical practice.

The optimal method of fixation for primary total hip replacements (THR), particularly fixation with or without the use of cement is still controversial.

In a systematic review and meta-analysis of all randomized controlled trials (RCT) comparing cemented versus uncemented THRS available in the published literature, we found that there is no significant difference between cemented and uncemented THRs in terms implant survival as measured by the revision rate.

Better short-term clinical outcome, particularly an improved pain score can be obtained with cemented fixation. However, the results are unclear for the long-term clinical and functional outcome between the two groups. No difference was evident in the mortality and the post operative complication rate. On the other hand, the Radiographic findings were variable and do not seem to correlate with clinical findings as differences in the surgical technique and prosthesis design might be associated with the incidence of osteolysis.

We concluded in our review that Cemented THR is similar if not superior to uncemented THR, and provides better short term clinical outcomes. Further research, improved methodology and longer follow up are necessary to better define specific subgroups of patients in whom the relative benefits of cemented and uncemented implant fixation can be clearly demonstrated.

Introduction

Unicompartmental knee arthroplasty (UKA) is a recognized procedure for treatment of medial compartment osteoarthritis. Patellofemoral (PF) joint degeneration is widely considered to be a contraindication to medial unicompartmental knee replacement. We examined the validity of this preconception using information gathered prospectively on consecutive patients who underwent UKA using the Repicci II® UKA prosthesis for medial compartment osteoarthritis.

Introduction

Proper femoral reaming is a key factor for a successful outcome in cementless hip arthroplasty. Good quality reaming minimizes risks of intra-operative femoral fracture during reaming and prevents poor fitting of the implant which can lead to subsidance of the stem postoperativly. Determining the quality of reaming is largely a subjective skill and dependant on the surgeon's experience with no documented intraoprative method to assess it objectively.

Introduction

Many surgeons are familiar with the audible change in the sound pitch while hammering a rasp in a long bone during surgeries like Hip Arthroplasty. We have developed a hypothesis indicating that there is a relationship between that sound change and the development of micro-fracture and subsequently full fracture.

Introduction: Vascular injuries associated with limb bone fractures are relatively uncommon.

Aim: To determine the mechanisms of injury and evaluate the outcome of combined orthopaedic and vascular injuries.

Method: A retrospective review of all patients with vascular injury associated with limb bone fractures between January 1992 and July 2006 was performed. Data collected included demographic details, clinical presentation, assessment, management and outcome.

Results: Of 22,340 fractures treated during the 14 years period 36 patients sustained a vascular injury that required surgical intervention. Of those, 18 patients (50%) had a concomitant fractures or other orthopaedic injury this group form the basis of the audit. The median age was 31.1 (range 3–80) years, and 66% were male.

Road traffic accidents accounted for 12 injuries (66%), other accidents 4(22%), iatrogenic injury 1(6%), and 1 gunshot injury (6%). Four patients had an associated nerve injury with varying severity. Skeletal fixation preceded vascular repair in most of the cases. Peroperative arterial shunting was not used in any patient. The primary vascular procedures included end-to-end anastamosis 2(11%), bypass grafting 1(6%), interposition vein grafts 8(43%), vein patch 1(6%), direct arterial repair 2(11%), ligation 2(11%), primary amputation 1(6%), reposition of normal course of artery 1(6%).

During a 17 months follow-up period, the upper and lower limb preservation rate was 100 and 89%, respectively. Nine patients (50%) were symptom free; three patients (16.6%) had a neurological deficit.

Conclusion: Vascular injury is uncommon in the orthopaedic patients. High suspicion and early intervention is essential to optimise outcome and function.

INTRODUCTION: After reconstructive forefoot surgery, patients require complete or partial forefoot relief, which can be obtained with a variety of shoe designs.

AIM: to review our experience with the use of the heel bearing shoes for forefoot weight relief and evaluate its use & application in our daily forefoot surgical practice

METHOD: A retrospective review of all (341) patients who underwent reconstructive forefoot surgery in our unit during the period of January 2003 to October 2007.

RESULTS: All patients used Barouk heel bearing shoes in the post operative period 283(83%) were females and 58(17%) were males. Average age was 56 years (range 14–84). In March 2006 we changed our postoperative protocol with the introduction of early physiotherapy for the lesser toes. 258 procedures performed between January 2003 to February 2006 (first group), while 83 procedures performed March 2006 to October 2007 (second group).

51(19.77%) from the first group reported stiffness of toes at 6 weeks review whilst only 3(3.61%) out of the second group.18 (6.98%) reported discomfort and stiffness of the hip from the first group in comparison to only 2(2.25%) patients in group two. From the first group 27(10.47%) reported knee stiffness while only one patient in the second group. The incidence of clinically significant low back pain was 12(4.65%) in the first group and 5(5.61%) patients in the second group.

CONCLUSION: heel weight bearing shoes play an important role following reconstructive forefoot surgery; however some problems may be encountered during their use. Early physiotherapy is essential to avoid these problems.

During a 3-year period in which 348 hallux valgus correction were performed, 10 patients with symptomatic hallux valgus deformity underwent triple osteotomies. All the 10 patients had intermetatarsal 1–2 angle of over 20 degrees and DMAA angle of over −10 degrees and no degenerative changes at MTP joint. They were studied retrospectively at an average follow-up of 9.7 months.

The surgical technique comprised a proximal open medial based wedge first metatarsl osteotomy and a distal closing medial based wedge first metatarsal osteotomy and a closing medial basal wedge phalangeal osteotomy. The average age of the patients at the time of surgery was 53.4 years.

At final follow-up, the average hallux valgus correction measured 22 degrees and the average intermetatarsal 1–2 angle correction was 9 degrees postoperatively. The DMAA averaged −4 degrees postoperatively the average length of the 1st metatarsal was shorter 2.43 mm postoperatively.

The average of the (VAS FA) score was improved from 55 preoperatively to 83.9 postoperatively.

8 patients were very satisfied, one patient was satisfied and one patient was unsatisfied. A hallux valgus deformity with an increased 1–2 intermetatasal angle over 20 degrees can be successfully treated with triple first ray osteotomies that maintain articular congruity of the the first metatarsophalangeal joint.
