This study aimed to investigate the outcomes of open tibia shaft fractures at a level one trauma center in a developing world setting. Specific objectives were to determine the association of time delay to antibiotic administration, surgical debridement, definitive skeletal stabilisation and soft tissue reconstruction, and the development of fracture-related infection (FRI). A retrospective cohort study included all adult patients with open tibia shaft fractures from July 2014 to June 2016 and January 2018 to December 2019. Patients who were skeletally immature at the time of injury, those with pathological fractures and who did not complete follow-up of at least three months were excluded. Patients were identified from hospital records. Data was captured in Microsoft Excel and analysed using STATISTICA. A Chi-squared was used to detect significant differences between groups. No association between infection and antibiotic administration was observed when patients were treated within or after 3 hours (p=0.625) or if patients had their first surgical debridement in theatre before or after 24 hours (p=0.259). Patients who waited more than five days for definitive skeletal fixation or soft tissue reconstruction had a significant increase in FRI (OR 4.7, 95% CI 2.0 – 10.9 and OR 4.7, 95% CI 2.0 – 11.0, respectively). Patients who underwent more than two formal debridements had a higher risk of developing FRI (OR 15.6, 95% CI 5.8 – 41.6). Whilst administration of antibiotics within 3 hours of presentation to the emergency unit had no impact on the development of FRI, time delays in managing open tibia shaft fractures are associated with an increased risk for FRI. Definitive soft tissue reconstruction and skeletal stabilization should not be delayed for more than five days

Aims and methods. We present a review of our use of the Ilizarov apparatus in a non-acute NGO hospital in Cambodia specialising in limb reconstruction. Frames are applied without on table image intensification. A retrospective case-note analysis of Ilizarov apparatus use for all indications was conducted. 53 frames were applied between November 2005 and October 2011. Indications for application were chronic open fracture, osteomyelitis, fracture malunion, infective and non-infective non-union, bone lengthening, primary bone tumour resection, ankle fusion, congenital deformity or pseudarthrosis, chronic hip dislocation, or a combination of the above. Results. Median delay in presentation was 104 weeks for all indications (range 4–864). Median treatment length was 21 weeks (3–76). The most frequent complication was pin-site infection. This occurred in 18 patients (34%). Return to theatre occurred in 21 patients (40%). Indications were frame adjustment, pin addition or removal, addition of bone graft or re-osteotomy. Failure of union occurred in three patients. These rates are comparable with those published in both Asian and Western literature. Conclusions. Our data demonstrate the versatility of the Ilizarov apparatus and its importance in limb reconstruction in a developing world setting. Our centre relies on it as a cost-effective tool for traditional and novel indications. In our centre the apparatus is applied without x-ray control and is maintained without a dedicated outreach pin-site care programme. Despite this our complication rates are comparable with western literature. We therefore recommend it as a safe and cost-effective tool for use in other developing world settings

Lateral meniscal failure and secondary valgus with lateral compartment arthrosis is quite common in the developed world. The varus knee is the common phenotype of the ‘jock’ of both genders, while the valgus knee is a common consequence of lateral meniscal tear, skiing or ‘catwalk’ life. Occurring more commonly in ‘flamingo’ phenotypes, lateral meniscal failure can be disabling, entirely preventing high heels being worn for instance. Indications. Lateral UKA is indicated for most valgus knees, and is substantially safer than TKA. ACL integrity is not essential in older people, as the patello-femoral mechanism is in line with the lateral compartment. Severe valgus with substantial bone loss is not a contraindication, if the deformity is simply angular. As long as there is not marked subluxation, fixed flexion deformity invariably corrects after notch osteophyte removal from femur and tibia. Combinations. Lateral UKA can be combined safely with PFJA: performed through a lateral approach, this is a safe and conservative procedure. ACL integrity is not essential – reconstruction can be undertaken simultaneously, if necessary. Combining lateral UKA with medial UKA is only rarely needed, and sometimes needs ACL reconstruction too. Adding a medial UKA in under 5 years usually results from overcorrection of the valgus. Mid Term Results, at a median of 7 years postop: Between 2005 to 2009, 64 knees in 58 patients had a lateral UKA using a device designed for the lateral compartment. This included 41 females and 17 males with a mean age of 71 years at the time of surgery (range 44–92). Thirty-nine patients underwent surgery on the right knee and 6 underwent bilateral procedures, of which four were performed under a single anesthetic. Primary lateral compartment osteoarthritis was the primary diagnosis in 63 cases with secondary osteoarthritis to a lateral tibial plateau fracture the indication in one patient. At 119 months follow up, the predicted cumulative survival was 0.97. With re-operation as an endpoint, 11% of patients within the study had undergone re-operation with a predicted cumulative survival of 0.81 at 119 months. This compares well with historic fixed bearing series. Preoperative OKS scores were available for 50 knees, scores were available for 63 knees at 9–48 months and 52 knees at 61–119 months post index operation. There was a significant improvement in the OKS between the preoperative scores (median 26 range 9–36) and early postoperative time points of 9–48 months, (median 42 range 23–48) (p<0.001). At the later postoperative time point of 61–119 months the score had been maintained (42 range 10–48). Conclusion. Lateral UKA is a small and safe procedure, with clinical outcomes that are equivalent to a medial UKA and are maintained at a median of 7 years postoperatively

The World Health Organisation (WHO) has recently identified musculoskeletal care as a major global health issue in the developing world. However, little is known about the quality and trends of orthopaedic research in resource-poor settings. The purpose of this study was to perform a systematic review of orthopaedic research in low-income countries (LIC). The primary objective was to determine the quality and publication parameters of studies performed in LIC. Secondary objectives sought to provide recommendations for successful strategies to implement research endeavors in LIC. A systematic review of the literature was performed by searching MEDLINE (1966-November 2014), EMBASE and the Cochrane Library to identify peer-reviewed orthopaedic research conducted in LICs. The PRISMA guidelines for performing a systematic review were followed. LIC were defined by the WHO and by the World Bank as countries with gross national income per capita equal or less than 1045US$. Inclusion criteria were (1) studies performed in a LIC, (2) conducted on patients afflicted by an orthopaedic condition, and (3) evaluated either an orthopaedic intervention or outcome. The Oxford Centre for Evidence-Based Medicine Levels of Evidence, and Grading of Recommendations Assessment, Development and Evaluation (GRADE) were used to objectively rate the overall methodological quality of each study. Additional data collected from these studies included the publication year, journal demographics, orthopaedic subspecialty and authors' country of origin. A total of 1,809 articles were screened and 277 studies met our inclusion criteria. Eighty-eight percent of studies conducted in LIC were of lower quality evidence according to the GRADE score and consisted mostly of small case series or case reports. Bangladesh and Nepal were the only two LIC with national journals and produced the highest level of research evidence. Foreign researchers produced over 70% of the studies with no collaboration with local LIC researchers. The most common subspecialties were trauma (42%) and paediatrics (14%). The 3 most frequent countries where the research originated were the United States (42%), United Kingdom (11%), and Canada (8%). The 3 most common locations where research was conducted were Haiti (18%), Afghanistan (14%), and Malawi (7%). The majority of orthopaedic studies conducted in LIC were of lower quality and performed by foreign researchers with little local collaboration. In order to promote the development of global orthopaedic surgery and research in LIC, we recommend (1) improving the collaboration between researchers in developed and LIC, (2) promoting the teaching of higher-quality and more rigorous research methodology through shared partnerships, (3) improving the capacity of orthopaedic research in developing nations through national peer-reviewed journals, and (4) dedicated subsections in international orthopaedic journals to global healthcare research

HIV and musculoskeletal trauma have reached epidemic proportions in the developing world especially in sub Saharan Africa. The epidemic has adversely affected health care delivery in limited resource settings. We assessed the outcome of HIV+ patients following spinal surgery for fractures and dislocations. Forty seven HIV+ patients were treated surgically over the past three years. The mean age was 32 years (19–53 years) and included 39 males. The dorsolumbar region was affected in 28 patients and the cervical spine in 19. Motor vehicle collisions (34) accounted for 72% of the injuries. Neurology occurred in 49% of patients (23). The mean CD4 count was 426 (range 98–742). The albumen was 29 gm/d? (range 26–34) and the lymphocyte count was 1.6c/cumm range 1.4–1.9). Twenty eight patients had generalized lymphadenopathy and recent weight loss was noted in 11 patients. Fifteen patients were treated for pulmonary TB and seven patients were on ARVs. The dislocations at the cervical spine commonly occurred at C5/6 (8). Three patients required a posterior cervical release with facetectomy prior to anterior cervical plating which was performed in all patients. The dislocations and unstable burst fractures of the dorsolumbar spine were treated by a one/two level posterior fusion. Post-operative sepsis due to S. aureus occurred in 8 (17%) patients. In four patients with deep infection vacuum dressings were used to clear the sepsis. Post-operative sepsis is best avoided by optimization of patients and meticulous surgery

Fracture neck of femur with delayed presentation in young patients can be a surgical challenge. Such scenarios are rare in the developed world but not uncommon in developing countries. To present the medium term results of open reduction and internal fixation accompanied by Quadratus Femoris muscle pedicle grafting in young patients who presented with a delay after sustaining a fracture neck of femur, 42 patients with fracture neck of femur with delayed presentation were treated with open reduction and internal fixation and supplemented with Quadratus Femoris muscle pedicle graft. A posterior approach was used in all cases. The patients were advised not to bear weight until there was clinical and radiological union. Functional recovery was assessed by gait and ability to squat on the floor. The age of the patients, predominantly male, ranged from 24 yrs to 50 yrs. Radiological union occurred on average at 6 months. Thirty-six patients proceeded to union; six patients had non-union and needed revision surgery. Complications included varus union in 9 cases; shortening greater than 2 cms occurred in 6 cases. Quadratus Femoris muscle pedicle grafting described by Meyer in the 1970s is useful in treating fracture neck of femur. Open reduction and internal fixation of the fracture neck of femur when supplemented with Quadratus Femoris muscle pedicle graft fixation promoted the union of fracture and preserved the head the femur

The increasing rate of fragility fractures in the developed world is now well- documented and presents a significant challenge to Orthopaedics. Although guidelines exist for the management of osteoporosis, both before and after fracture events, little work has yet been done to measure the effect of interventions on reducing the rate of second fractures in the at-risk population. The longitudinal study, begun at The Canberra Hospital, aims to compare rates of second fractures in two populations of patients over 40 years who have sustained a low-impact, minor trauma fracture. A retrospective study of medical records provides baseline information on current intervention rates for osteoporosis. Secondly, a prospective study population is recruited from patients presenting to Fracture Clinic at The Canberra Hospital. Patients presenting to clinic will, after consent, undergo a screening process including blood test and DEXA scans, to confirm or reject a diagnosis of osteoporosis. Those diagnosed will be referred for medical management as well as non-pharmacological interventions. Follow-up will be conducted at 12 months with repeat testing for bone density to determine whether the interventions have produced measurable improvement and patients will be followed up for five years to establish the rate of re-fracture. A progress report will be presented to the conference advising on findings from the retrospective arm, scheduled for completion in September 2009, and results to date of the prospective arm. The study is a current work-in-progress, and will provide a basis for future research in this area

A high volume of trauma and limited resources means that traditional methods of bone reconstruction are not feasible in parts of Africa. We present the management and outcomes of using Masquelet's concept, of an induced membrane and secondary morcellised cancellous bone grafting, in patients with severe lower limb trauma. Eleven patients were treated in an orthopaedic department in rural southern Africa between 2011 and 2012. This is a subgroup that is part of a larger study of open fractures that received ethical approval. All patients were male, with ten aged between 20 and 35 and one aged 70. Two were HIV positive. There were three open femur and eight open tibia fractures. Three required fasciocutaneous flaps and one required a muscle flap to achieve adequate soft tissue coverage. Eight cases were performed as the primary treatment and three were to treat septic non-unions. Bone defects ranged from 4 to 10 cm. Definitive bony stabilisation was maintained by mono-lateral external fixator in three patients. In other cases this was converted to a circular frame or internal fixation. The results have been mixed. In three patients bone grafting was delayed due to wound or pin site problems. In one case the bone graft was lost due to infection but repeating the procedure produced a good result. Time to bony union in each case is difficult to quantify. However, there is clear evidence of new bone forming in most cases. Four patients are weight bearing with external fixation removed, as are five patients with internal fixation. In a few cases bony union appears to be taking significantly longer, if at all. Masquelet technique is a welcome addition to the options available in bone reconstruction. However, time to achieve bony union is unpredictable. Refinement of the technique for use in the developing world is needed

Introduction. The resurgence of TB worldwide has several underlying causes, but HIV infection has undoubtedly been a key factor in the current TB epidemic. Since TB is endemic in the developing world the influence of HIV is of concern, particularly with the emergence of multi-drug-resistant strains. The remarkable susceptibility of patients with AIDS to develop TB has shown the critical role of CD4 lymphocytes in protective immunity. In the absence of immunological surveillance by CD4 cells, 5-10% of persons with latent foci of TB reactivate each year. Aim. This paper highlights the presentation and outcome following treatment in HIV patients with spinal TB. Methods. 81 HIV+ve patients with spinal tuberculosis were prospectively evaluated between 2006 and 2007. The mean age was 31 years and 63% were females. The thoracic spine was affected in 45, lumbar (33) and cervical (3). Non-contiguous lesions were noted in six patients. Sixty-six (81%) patients had neurological deficit. The mean Hb was (10.1gm/dl), mean WCC 4.9, mean lymphocyte count was 1.8, mean ESR 79mm/h and the mean CD4 count was 268 cell/cumm. Co-morbidities were seen in 68% of patients. All patients were optimised prior to treatment. Posterolateral decompression was performed in 29 cases, anterior decompression (25), needle biopsy (13), incision and drainage 5 and 9 were treated non-operatively. Medication included ARV (72 patients) and anti-TB in all patients. Results. The mean follow-up was 21 months. Eleven (13.5%) patients developed wound infection and one child died. Complete recovery occurred in 23 patients (35%). The mean CD4 count was 341 cell/cumm. Conclusion. The short term results are encouraging. These patients are best managed by a multidisciplinary team to monitor potential complications from dual therapy, to ensure compliance and adequate nutrition

Aims

Deprivation underpins many societal and health inequalities. COVID-19 has exacerbated these disparities, with access to planned care falling greatest in the most deprived areas of the UK during 2020. This study aimed to identify the impact of deprivation on patients on growing waiting lists for planned care.

Introduction. Are there really ‘conventional’ bearings, offering more security and less risk than the ‘alternative’ bearings that feature in the programme?. Alternative, when used as an adjective has 2 meanings:. offering or expressing a choice, as in several alternative plans. different from or functioning outside the usual or conventional:. eg alternative newspaper, alternative rock music, alternative medicine. This paper reviews the elements that make up the bearing couples available today in the developed world, and tests each bearing against these meanings. Materials. what are the alternatives?. The materials available today fall into the following broad families:. Metals. Stainless Steel and Cobalt-Chromium Alloy, are the dominant metals available. There is no variation in the Steel, but the characterisation of the Co-Cr does vary. Several manufacturers use different carbide content for the femoral and acetabular components, and different processes. One has been withdrawn from the market, and others may be at risk of this, although it is not the material itself that seems to be the main issue. Ceramics include alumina and zirconia ceramics. Alumina has been available unchanged for over 40 years, although delta ceramic (a zirconia toughened alumina) has only been available unchanged since 2001, making in available for 10 years. Polymers. a huge range of polyethylenes are now available, with different individual claims. All claim superior wear resistance, and oxidation resistance. More than 20 unique products are available in the EU, each with a proprietary formula giving individual characteristics. Coatings and surface treatments. these are now available today from many companies, who either ceramicise the surface of cobalt chrome or titanium with titanium nitride, or use oxinium (a proprietary product from a single company). Bearing couples. what are the alternatives Symmetric and Asymmetric bearings are currently offered. Symmetric bearings are available for Ceramic on Ceramic and Metal on Metal bearings only. Asymmetric bearings are available with metals, including metal on poly, and metal on peek. Ceramics can couple with metal or polymers. Bearing Sizes. Larger than 32mm should be considered ‘alternative’. The larger metal bearings have seen the start of crevice corrosion at the taper between titanium and Co-Cr, and even between different Co-Cr alloys. This new class of complication seems to be unique to metal femoral heads. Bearing-stem compatibility. Larger metal on metal head bearings have brought an entirely new world of complications. The choices of trunion are mainly twofold: the 12/14 tapers which differ significantly between products, and the V40 taper still used by one manufacturer. Neither was designed for use with a larger diameter head. Conclusions. The use of the word ‘alternative’ implies a ‘standard’ or conventional bearing. Ceramic bearings have changed least, have been immune from the metallosis and crevice corrosion seen with large ball Metal head whether bearing on metal or polyethylene. They also have reassuring long term results. In 2011 they should be considered the standard bearing for the young and active patient. The large diameter metal on highly cross-linked poly bearings should now be considered ‘alternative’

Accurate in vivo knee joint contact forces are required for joint simulator protocols and finite element models during the development and testing of total knee replacements (Varadarajan et al., 2008.) More accurate knowledge of knee joint contact forces during high flexion activities may lead to safer high flexion implant designs, better understanding of wear mechanisms, and prevention of complications such as aseptic loosening (Komistek et al., 2005.) High flexion is essential for lifestyle and cultural activities in the developing world, as well as in Western cultures, including ground-level tasks and chores, prayer, leisure, and toileting (Hemmerich et al., 2006.) In vivo tibial loads have been reported while kneeling; but only while the subject was at rest in the kneeling position (Zhao et al., 2007), meaning that the loads were submaximal due to muscle relaxation and thigh-calf contact support. The objective of this study was to report the in vivo loads experienced during high flexion activities and to determine how closely the measured axial joint contact forces can be estimated using a simple, non-invasive model. It provides unique data to better interpret non-invasively determined joint-contact forces, as well as directly measured tiobiofemoral joint contact force data for two subjects. Two subjects with instrumented tibial implants performed kneeling and deep knee bend activities. Two sets of trials were carried out for each activity. During the first set, an electromagnetic tracking system and two force plates were used to record lower limb kinematics and ground reaction forces under the foot and under the knee when it was on the ground. In the second set, three-dimensional joint contact forces were directly measured in vivo via instrumented tibial implants (Heinlein et al., 2007.) The measured axial joint contact forces were compared to estimates from a non-invasive joint contact force model (Smith et al., 2008.). The maximum mean axial forces measured during the deep knee bend were 24.2 N/kg at 78.2° flexion (subject A) and 31.1 N/kg at 63.5° flexion (subject B) during the deep knee bend (Figure 1.) During the kneeling activity, the maximum mean axial force measured was 29.8 N/kg at 86.8° flexion (subject B.) While the general shapes of the model-estimated curves were similar to the directly measured curves, the axial joint contact force model underestimated the measured contact forces by 7.0 N/kg on average (Figure 2.) The most likely contributor to this underestimation is the lack of co-contraction in the model. The study protocol was limited in that data could not be simultaneously collected due to electromagnetic interference between the motion tracking system and the inductively powered instrumented tibial component. Because skin-mounted markers were used, kinematics may be affected by skin motion artefacts. Despite these limitations, this study presents valuable information that will advance the development of high flexion total knee replacements. The study provides in vivo measurements and non-invasive estimates of joint contact forces during high flexion activities that can be used for joint simulator protocols and finite element modeling

We compared the use of broth culture medium for samples taken in theatre with the standard practice of placing tissue samples in universal containers. A total of 67 consecutive patients had standard multiple samples of deep tissue harvested at surgery and distributed equally in theatre either to standard universal containers or to broth culture medium. These samples were cultured by direct and enrichment methods. The addition of broth in theatre to standard practice led to an increase in sensitivity from 83% to 95% and an increase in negative predictive value from 77% to 91%. Placing tissue samples directly into broth in the operating theatre is a simple, inexpensive way to increase the sensitivity of cultures from infected patients, and does not appear to compromise the specificity of these cultures.

A two-year retrospective survey in southern Ethiopia revealed that 49 amputations had been performed, 25 of which were for gangrene following tight splintage applied by traditional bone setters. The aim of this study was to determine if it was possible to reduce this incidence of gangrene by offering one-day instructional courses to bone setters. In ten separate one-day courses 112 tradition healers attended. In addition, two-day courses were given to local health assistants, who also received written instructions for the safe care of fractures. A two-year prospective study revealed a marked reduction in amputations, from 49 to 25, with only seven rather than 25 being required for gangrene.

We found that it is possible to educate traditional healers so that fewer gangrenous limbs require to be amputated.

In order to assess the efficacy of inspection and accreditation by the Specialist Advisory Committee for higher surgical training in orthopaedic surgery and trauma, seven training regions with 109 hospitals and 433 Specialist Registrars were studied over a period of two years.

There were initial deficiencies in a mean of 14.8% of required standards (10.3% to 19.2%). This improved following completion of the inspection, with a mean residual deficiency in 8.9% (6.5% to 12.7%.) Overall, 84% of standards were checked, 68% of the units improved and training was withdrawn in 4%.

Most units (97%) were deficient on initial assessment. Moderately good rectification was achieved but the process of follow-up and collection of data require improvement. There is an imbalance between the setting of standards and their implementation. Any major revision of the process of accreditation by the new Post-graduate Medical Education and Training Board should recognise the importance of assessment of training by direct inspection on site, of the relationship between service and training, and the advantage of defining mandatory and developmental standards.
