Aims

Liposomal bupivacaine (LB) as part of a periarticular injection protocol continues to be a highly debated topic in total knee arthroplasty (TKA). We evaluated the effect of discontinuing the use of LB in a periarticular protocol on immediate postoperative pain scores, opioid consumption, and objective functional outcomes.

Aims

This study evaluated variation in the surgical treatment of stable (A1) and unstable (A2) trochanteric hip fractures among an international group of orthopaedic surgeons, and determined the influence of patient, fracture, and surgeon characteristics on choice of implant (intramedullary nailing (IMN) versus sliding hip screw (SHS)).

Aims

The aim of this study was to assess the effects of transferring patients to a specialized arthroplasty centre between the first and second stages (interstage) of prosthetic joint infection (PJI) of the knee.

Aims

The aim of this study was to assess the current trends in the estimation of survival and the preferred forms of treatment of pathological fractures among national and international general and oncological orthopaedic surgeons, and to explore whether improvements in the management of these patients could be identified in this way.

Aims

Informed patient consent is a legal prerequisite endorsed by multiple regulatory institutions including the Royal College of Surgeons and the General Medical Council. It is also recommended that the provision of written information is available and may take the form of a Patient Information Leaflet (PIL) with multiple PILs available from leading orthopaedic institutions. PILs may empower the patient, improve compliance, and improve the patient experience. The national reading age in the United Kingdom is less than 12 years and therefore PILs should be written at a readability level not exceeding 12 years old. We aim to assess the readability of PILs currently provided by United Kingdom orthopaedic institutions.

Aims

The objective of this study was to investigate bone healing after internal fixation of displaced femoral neck fractures (FNFs) with the Dynamic Locking Blade Plate (DLBP) in a young patient population treated by various orthopaedic (trauma) surgeons.

Aims

Tuberculosis (TB) infection of bones and joints accounts for 6.7% of TB cases in England, and is associated with significant morbidity and disability. Public Health England reports that patients with TB experience delays in diagnosis and treatment. Our aims were to determine the demographics, presentation and investigation of patients with a TB infection of bones and joints, to help doctors assessing potential cases and to identify avoidable delays.

Aims

Calcium sulphate (CaSO₄) is a resorbable material that can be used simultaneously as filler of a dead space and as a carrier for the local application of antibiotics. Our aim was to describe the systemic exposure and the wound fluid concentrations of vancomycin in patients treated with vancomycin-loaded CaSO₄ as an adjunct to the routine therapy of bone and joint infections.

The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.

We assessed the orientation of the acetabular component in 1070 primary total hip arthroplasties with hard-on-soft, small diameter bearings, aiming to determine the size and site of the target zone that optimises outcome. Outcome measures included complications, dislocations, revisions and ΔOHS (the difference between the Oxford Hip Scores pre-operatively and five years post-operatively). A wide scatter of orientation was observed (2sd 15°). Placing the component within Lewinnek’s zone was not associated withimproved outcome. Of the different zone sizes tested (± 5°, ± 10° and ± 15°), only ± 15° was associated with a decreased rate of dislocation. The dislocation rate with acetabular components inside an inclination/anteversion zone of 40°/15° ± 15° was four times lower than those outside. The only zone size associated with statistically significant and clinically important improvement in OHS was ± 5°. The best outcomes (ΔOHS > 26) were achieved with a 45°/25° ± 5° zone.

This study demonstrated that with traditional technology surgeons can only reliably achieve a target zone of ±15°. As the optimal zone to diminish the risk of dislocation is also ±15°, surgeons should be able to achieve this. This is the first study to demonstrate that optimal orientation of the acetabular component improves the functional outcome. However, the target zone is small (± 5°) and cannot, with current technology, be consistently achieved.

The Unified Classification System (UCS) was introduced because of a growing need to have a standardised universal classification system of periprosthetic fractures. It combines and simplifies many existing classification systems, and can be applied to any fracture around any partial or total joint replacement occurring during or after operation. Our goal was to assess the inter- and intra-observer reliability of the UCS in association with knee replacement when classifying fractures affecting one or more of the femur, tibia or patella.

We used an international panel of ten orthopaedic surgeons with subspecialty fellowship training and expertise in adult hip and knee reconstruction (‘experts’) and ten residents of orthopaedic surgery in the last two years of training (‘pre-experts’). They each received 15 radiographs for evaluation. After six weeks they evaluated the same radiographs again but in a different order.

The reliability was assessed using the Kappa and weighted Kappa values.

The Kappa values for inter-observer reliability for the experts and the pre-experts were 0.741 (95% confidence interval (CI) 0.707 to 0.774) and 0.765 (95% CI 0.733 to 0.797), respectively. The weighted Kappa values for intra-observer reliability for the experts and pre-experts were 0.898 (95% CI 0.846 to 0.950) and 0.878 (95% CI 0.815 to 0.942) respectively.

The UCS has substantial inter-observer reliability and ‘near perfect’ intra-observer reliability when used for periprosthetic fractures in association with knee replacement in the hands of experienced and inexperienced users.

Trauma and orthopaedics is the largest of the surgical specialties and yet attracts a disproportionately small fraction of available national and international funding for health research. With the burden of musculoskeletal disease increasing, high-quality research is required to improve the evidence base for orthopaedic practice. Using the current research landscape in the United Kingdom as an example, but also addressing the international perspective, we highlight the issues surrounding poor levels of research funding in trauma and orthopaedics and indicate avenues for improving the impact and success of surgical musculoskeletal research.

We present a review of litigation claims relating to foot and ankle surgery in the NHS in England during the 17-year period between 1995 and 2012.

A freedom of information request was made to obtain data from the NHS litigation authority (NHSLA) relating to orthopaedic claims, and the foot and ankle claims were reviewed.

During this period of time, a total of 10 273 orthopaedic claims were made, of which 1294 (12.6%) were related to the foot and ankle. 1036 were closed, which comprised of 1104 specific complaints. Analysis was performed using the complaints as the denominator. The cost of settling these claims was more than £36 million.

There were 372 complaints (33.7%) involving the ankle, of which 273 (73.4%) were related to trauma. Conditions affecting the first ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective practice. Overall, claims due to diagnostic errors accounted for 210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery and 149 (13.5%) from alleged mismanagement.

Our findings show that the incorrect, delayed or missed diagnosis of conditions affecting the foot and ankle is a key area for improvement, especially in trauma practice.

We report the effect of introducing a dedicated Ponseti service on the five-year treatment outcomes of children with idiopathic clubfoot. Between 2002 and 2004, 100 feet (66 children; 50 boys and 16 girls) were treated in a general paediatric orthopaedic clinic. Of these, 96 feet (96%) responded to initial casting, 85 requiring a tenotomy of the tendo-Achillis. Recurrent deformity occurred in 38 feet and was successfully treated in 22 by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior, The remaining 16 required an extensive surgical release. . Between 2005 and 2006, 72 feet (53 children; 33 boys and 20 girls) were treated in a dedicated multidisciplinary Ponseti clinic. All responded to initial casting: 60 feet (83.3%) required a tenotomy of the tendo-Achillis. Recurrent deformity developed in 14, 11 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior. The other three required an extensive surgical release. . Statistical analysis showed that children treated in the dedicated Ponseti clinic had a lower rate of recurrence (p = 0.068) and a lower rate of surgical release (p = 0.01) than those treated in the general clinic. This study shows that a dedicated Ponseti clinic, run by a well-trained multidisciplinary team, can improve the outcome of idiopathic clubfoot deformity.

Exsanguination is the second most common cause of death in patients who suffer severe trauma. The management of haemodynamically unstable high-energy pelvic injuries remains controversial, as there are no universally accepted guidelines to direct surgeons on the ideal use of pelvic packing or early angio-embolisation. Additionally, the optimal resuscitation strategy, which prevents or halts the progression of the trauma-induced coagulopathy, remains unknown. Although early and aggressive use of blood products in these patients appears to improve survival, over-enthusiastic resuscitative measures may not be the safest strategy.

This paper provides an overview of the classification of pelvic injuries and the current evidence on best-practice management of high-energy pelvic fractures, including resuscitation, transfusion of blood components, monitoring of coagulopathy, and procedural interventions including pre-peritoneal pelvic packing, external fixation and angiographic embolisation.

We present a review of claims made to the NHS Litigation Authority (NHSLA) by patients with conditions affecting the shoulder and elbow, and identify areas of dissatisfaction and potential improvement. Between 1995 and 2012, the NHSLA recorded 811 claims related to the shoulder and elbow, 581 of which were settled. This comprised 364 shoulder (64%), and 217 elbow (36%) claims. A total of £18.2 million was paid out in settled claims. Overall diagnosis, mismanagement and intra-operative nerve injury were the most common reasons for litigation. The highest cost paid out resulted from claims dealing with incorrect, missed or delayed diagnosis, with just under £6 million paid out overall. Fractures and dislocations around the shoulder and elbow were common injuries in this category. All 11 claims following wrong-site surgery that were settled led to successful payouts.

This study highlights the diagnoses and procedures that need to be treated with particular vigilance. Having an awareness of the areas that lead to litigation in shoulder and elbow surgery will help to reduce inadvertent risks to patients and prevent dissatisfaction and possible litigation.

The purpose of this study was to establish whether exploration and neurolysis is an effective method of treating neuropathic pain in patients with a sciatic nerve palsy after total hip replacement (THR). A total of 56 patients who had undergone this surgery at our hospital between September 1999 and September 2010 were retrospectively identified. There were 42 women and 14 men with a mean age at exploration of 61.2 years (28 to 80). The sciatic nerve palsy had been sustained by 46 of the patients during a primary THR, five during a revision THR and five patients during hip resurfacing. The mean pre-operative visual analogue scale (VAS) pain score was 7.59 (2 to 10), the mean post-operative VAS was 3.77 (0 to 10), with a resulting mean improvement of 3.82 (0 to 10). The pre- and post-neurolysis VAS scores were significantly different (p < 0.001). Based on the findings of our study, we recommend this form of surgery over conservative management in patients with neuropathic pain associated with a sciatic nerve palsy after THR.

Many tumors metastasise to bone, therefore, pathologic fracture and impending pathologic fractures are common reasons for orthopedic consultation. Having effective treatment strategies is important to avoid complications, and relieve pain and preserve function. Thorough pre-operative evaluation is recommended for medical optimization and to ensure that the lesion is in fact a metastasis and not a primary bone malignancy. For impending fractures, various scoring systems have been proposed to determine the risk of fracture, and therefore the need for prophylactic stabilisation. Lower score lesions can often be treated with radiation, while more problematic lesions may require internal fixation. Intramedullary fixation is generally preferred due to favorable biomechanics. Arthroplasty may be required for lesions with massive bony destruction where internal fixation attempts are likely to fail. Radiation may also be useful postoperatively to minimise construct failure due to tumor progression.
