Circular frame versus reamed intramedullary tibial nail in the treatment of grade III open tibial diaphyseal fractures.

BACKGROUND: Grade III open tibial diaphyseal fractures are challenging to treat and controversy exists on whether to treat them with an intramedullary nail (IMN) or a circular frame (CF). This study aims to compare outcomes for intramedullary nail and circular frame in the treatment of open tibial diaphyseal fractures. METHODOLOGY: Retrospective study at a major trauma center of all patients admitted with a grade III open tibial diaphyseal fracture between January 2016 and January 2022. The primary outcome measures were major complications: non-union, malunion, refracture, DBI and amputation. Secondary outcome measures were time to union and reoperation rates. RESULTS: Fifty-five patients were included in the study, 32 patients in CF group and 23 patients in IMN group. There were no significant differences in the baseline demographics of patients in both groups. Major complications were recorded in 13 limbs (54%) in IMN group and in 18 limbs (56%) in CF group which were not statistically significant (p = 0.797). Deep bone infection rates were noted in 4 (12.5%) in the CF group, compared to 1 (4%) in IMN group; however, the result was not statistically significant (p = 0.240). Amputation rates as a result of infected non-unions were seen in 1 limb (4%) in IMN group and 2 limbs (6%) in CF group (p = 0.99). Median time to union was significantly shorter in IMN group at 30 weeks compared to 30 weeks for CF group (p = 0.04). CONCLUSION: IMN should be the treatment of choice in the treatment of grade III open tibial diaphyseal fracture, but CF should be considered for delayed treatment and in patients with bone loss.

Is It Safe to Perform Revision Hip Arthroplasty Without Suction Drains?

Background There is a number of studies showing no significant benefit of using drains after primary hip arthroplasty. However, there is no consensus in the literature about the usage of drains in revision hip replacement. This study aims to assess the effect of drains in revision hip arthroplasty. Methods A retrospective analysis was performed of all consecutive revision hip replacement surgeries performed at our unit over a five-month period (November 2018 to March 2019). Case notes, laboratory investigations, and operative records were reviewed. The effects of drains on postoperative hemoglobin (Hb), transfusion rate, and complications were analyzed. Results Overall, 92 patients were analyzed who underwent revision hip replacement during the study period. There were 46 male and 46 female patients with a mean age of 72 years. Aseptic loosening was the most common indication for the revision (41 patients) followed by instability (21 patients), infection (11 patients), and periprosthetic fractures (eight patients). Seventy-two patients had no drains while suction drains were used in 20 patients. Both groups were similar regarding age, sex, and indications for revision surgery. There was a significantly higher drop in postoperative Hb in patients with drains than those without drains (33 g/L: 27 g/L, p=0.03). There were significantly more blood transfusions in patients with drains as compared to those without drains (15%: 8%, relative risk 1.8, and odds ratio 1.94). There was no difference in both groups with regard to returning to the theater. Discussion Use of suctions drains in revision hip surgery was associated with increased postoperative blood loss and increased requirement for postoperative blood transfusion. Revision hip surgery without routine usage of suction drains did not increase wound complications. Conclusion Revision surgery without routine usage of drains is safe and may decrease postoperative blood loss and the rate of transfusion.

Does Delayed Ligament Reconstruction Surgery Lead to Poor Outcomes in Patients With Multiligament Knee Injuries?

Background and objective Multiligament knee injuries (MLKIs) are difficult to treat, and poor outcomes have been reported after conservative management. Controversy exists as to how to surgically manage these complex injuries. The aim of our study was to evaluate the midterm patient-reported outcomes after delayed multiligament knee reconstruction. Methods This was a review of a prospectively kept database of all patients undergoing surgery for multiligament reconstruction at a single institution. A total of 51 patients were included in the study, with a median follow-up of 48 months. In addition to the patient-reported outcomes, we also looked at other factors that could potentially affect the outcomes. Results At the final follow-up, there was no significant difference between the range of motion (ROM) of the injured knee compared to that of the healthy knee. Patients having surgery >6 months after injury had similar outcomes when compared to those having surgery <6 months post-injury. Female patients and patients with a BMI >30 had inferior outcomes. Conclusion Good midterm results can be expected after delayed multiligament knee reconstruction. Patients with a BMI >30 and female patients were observed to have inferior outcomes.

Coronavirus in hip fractures (CHIP) 4 : has vaccination improved mortality outcomes in hip fracture patients?

AIMS: Prior to the availability of vaccines, mortality for hip fracture patients with concomitant COVID-19 infection was three times higher than pre-pandemic rates. The primary aim of this study was to determine the 30-day mortality rate of hip fracture patients in the post-vaccine era. METHODS: A multicentre observational study was carried out at 19 NHS Trusts in England. The study period for the data collection was 1 February 2021 until 28 February 2022, with mortality tracing until 28 March 2022. Data collection included demographic details, data points to calculate the Nottingham Hip Fracture Score, COVID-19 status, 30-day mortality, and vaccination status. RESULTS: A total of 337 patients tested positive for COVID-19. The overall 30-day mortality in these patients was 7.7%: 5.5% in vaccinated patients and 21.7% in unvaccinated patients. There was no significant difference between post-vaccine mortality compared with pre-pandemic 2019 controls (7.7% vs 5.0%; p = 0.068). Independent risk factors for mortality included unvaccinated status, Abbreviated Mental Test Score ≤ 6, male sex, age > 80 years, and time to theatre > 36 hours, in decreasing order of effect size. CONCLUSION: The vaccination programme has reduced 30-day mortality rates in hip fracture patients with concomitant COVID-19 infection to a level similar to pre-pandemic. Mortality for unvaccinated patients remained high.Cite this article: Bone Joint J 2022;104-B(12):1362-1368.

Hip fracture mortality in patients co-infected with coronavirus disease 2019: a comparison of the first two waves of the United Kingdom pandemic during the pre-vaccine era.

AIMS: In the UK, deaths associated with COVID-19 have occurred in two waves. Evidence has shown an increase in 30-day mortality for hip fracture patients co-infected with COVID-19. However, there are no studies analysing mortality trends between the first two waves of the UK pandemic. Additionally, hospital versus community acquired COVID-19 infection between the two waves has not been analysed. Furthermore, predictive factors of 30-day mortality have not been fully evaluated. METHODS: Data from two audits conducted by the CHIP collaborative group were used: a published regional audit in England of nine hospitals providing the COVID-19 negative cases and an unpublished UK national audit of 43 hospitals, which provided the COVID-19 positive cases. Data collection for the COVID-19 positive cases was from 23 March to 31 December 2020. September 1, 2020 was used to define the transition between the two waves. RESULTS: There were 517 COVID-19 positive hip fracture patients and 1445 COVID-19 negative hip fracture patients. Overall, 30-day mortality rates were 5.7% in the COVID-19 negative group and 22.4% in the COVID-19 positive patients (p < 0.001). A difference in survival function between the first and second waves was found (p = 0.038). To allow for significant demographic differences, a matched analysis of 185 patients found a 26.5% 30-day mortality in the first wave compared to 21.1% in the second wave (p = 0.222). Within the COVID-19 positive groups, the virus was hospital acquired in 66.7% of cases in the first wave and 72.8% of cases in the second wave (p = 0.130). Independent predictors of mortality were found to include COVID-19 positive status, AMTS ≤ 6, male gender and age. CONCLUSION: There was a reduction in 30-day mortality for hip fracture patients co-infected with COVID-19 between the two UK pandemic waves but this was not statistically significant. There was no reduction in hospital acquired COVID-19 infection between the two waves.

Efficacy and safety of tranexamic acid in hip fracture surgery: A comparative study of 613 patients.

BACKGROUND: Blood loss is a major concern in the frail elderly patient undergoing hip fracture surgery. The objective of this study was to investigate the efficacy of tranexamic acid in reducing blood loss and allogenic blood transfusions. The study also investigated the safety profile by comparing rates of thromboembolic events. METHODS: A total of 613 patients with hip fractures were included in the study. Patients received 1g of tranexamic acid on induction of anaesthesia. Postoperative haemoglobin was measured on day one. Blood loss was calculated, and blood transfusion was recorded. RESULTS: Tranexamic acid use resulted in a higher mean postoperative haemoglobin (110.3 ± 15.9 vs 106.8 ± 16.2; p = 0.023) and reduced mean estimated blood loss (571.3 ± 150.4 vs 678.3 ± 201.2; p = 0.001). There was also a significantly reduced number of transfusions in tranexamic acid group (13% vs 28%; p = 0.002). There was no difference in rates of deep vein thrombosis (4 vs 3; p = 0.98) or pulmonary embolism (2 vs 2; p = 1). CONCLUSION: The use of tranexamic acid is effective in reduction of blood loss and rates of blood transfusion, without an apparent increase in adverse thromboembolic events.

Coronavirus infection in hip fractures (CHIP) study.

AIMS: Despite the COVID-19 pandemic, incidence of hip fracture has not changed. Evidence has shown increased mortality rates associated with COVID-19 infection. However, little is known about the outcomes of COVID-19 negative patients in a pandemic environment. In addition, the impact of vitamin D levels on mortality in COVID-19 hip fracture patients has yet to be determined. METHODS: This multicentre observational study included 1,633 patients who sustained a hip fracture across nine hospital trusts in North West England. Data were collected for three months from March 2020 and for the same period in 2019. Patients were matched by Nottingham Hip Fracture Score (NHFS), hospital, and fracture type. We looked at the mortality outcomes of COVID-19 positive and COVID-19 negative patients sustaining a hip fracture. We also looked to see if vitamin D levels had an impact on mortality. RESULTS: The demographics of the 2019 and 2020 groups were similar, with a slight increase in proportion of male patients in the 2020 group. The 30-day mortality was 35.6% in COVID-19 positive patients and 7.8% in the COVID-19 negative patients. There was a potential association of decreasing vitamin D levels and increasing mortality rates for COVID-19 positive patients although our findings did not reach statistical significance. CONCLUSION: In 2020 there was a significant increase in 30-day mortality rates of patients who were COVID-19 positive but not of patients who were COVID-19 negative. Low levels of vitamin D may be associated with high mortality rates in COVID-19 positive patients. Cite this article: Bone Joint J 2021;103-B(4):782-787.

Pre-injury use of antiplatelet and anticoagulations therapy are associated with increased mortality in a cohort of 1038 hip fracture patients.

BACKGROUND: Hip fractures are a large burden on the health care systems of developed nations. Patients usually have multiple co-morbidities and the pre-injury use of anticoagulants and anti-platelet medication is common. MATERIALS AND METHODS: This study used a single hospital hip fracture database to facilitate a retrospective analysis of the impact of anti-coagulation and anti-platelet therapy on mortality and complications after surgical management of hip fractures. There were 92 patients on warfarin, 69 on DOAC, 260 antiplatelet patients and 617 control patients. RESULTS: Mortality rates at 30 days were 4.8% for the control group, 12.6% for the antiplatelet group, warfarin 7.0%, 9.5% for Direct Oral Anticoagulant (DOAC) group, p = 0.004. Mortality rates at 1 year were 22.4% for the control group, 32.3% for the antiplatelet group, 29.3% for the warfarin group and 29.0% for DOAC group (p=0.007). Amongst complications, significant differences were found in transfusion (DOAC) and wound ooze (warfarin) rates, but the study did not detect significant clinical consequences arising from these differences. A matched analysis for age, sex, and ASA was undertaken to look in more detail at mortality data. Some mortality differences remained between groups with anti-platelet medication associated with increased mortality, but the differences no longer appeared to be significant. Our data suggests that this is a non-causal association, which could be incorporated into predictive mortality risk scores such as the Nottingham hip fracture score. CONCLUSION: We believe that pre-injury antiplatelet therapy is a strong indicator for high risk patients with higher expected mortality after hip fracture surgery. We saw no evidence to support delayed surgery in patients taking DOACs.

Wound Closure in Flexion versus Extension following Total Knee Replacement: Outcomes and Complications.

Position of the knee may affect the range of movement (ROM) after a total knee replacement (TKR). It has been postulated that wound closure in extension may cause shortening of the extensor mechanism and increased tension on the soft tissues. The aim of this study was to determine effect of wound closure in TKR with the knee in flexion or extension on postoperative ROM and rehabilitation. A consecutive series of 121 patients underwent primary TKR between May 2011 and August 2012. Group A (60 patients) had wound closure in extension. Group B (61 patients) had wound closure in flexion. Baseline demographic data were compared-age, body mass index, gender, American Society of Anesthetists status, length of stay, wound healing, and ROM. Oxford Knee Score (OKS) were assessed at 6 months, 1 year, and 2 years. Fifty-two males and 69 females with average age of 68 years (32-86) underwent TKR. There were no wound complications requiring surgical intervention. One patient in each group required manipulation under anesthesia for stiffness. There was no statistical difference in ROM and OKS at the last follow-up. There was no difference in outcomes following knee closure in flexion or extension.

Tranexamic acid versus fibrin sealant in primary total hip replacement: a comparative study.

BACKGROUND: The effectiveness of intravenous tranexamic acid (TA) in reducing blood loss and transfusion requirements during total hip replacement (THR) is well recognised. The aim of this study was to assess the effectiveness of a fibrin sealant in comparison to intravenous TA and a control group. PATIENTS AND METHODS: We prospectively studied 273 patients with primary hip osteoarthritis who underwent a THR between February 2012 and September 2013. The first 73 patients acted as the control group. The next 100 consecutive patients received fibrin sealant spray, and the last 100 patients received 1 g TA on induction. RESULTS: The demographic characteristics, surgical time, surgeon grade, anaesthetic type and pre-operative haemoglobin of the three groups were comparable. Both fibrin sealant and intravenous TA were effective in reducing blood loss during THR (15%, p = 0.04 and 22.5%, p = 0.01, respectively), when compared to the control group. However, neither treatment was found to be superior to the other in preventing blood loss p = 0.39. Tranexamic acid was superior to fibrin sealant in decreasing allogeneic transfusion requirements (0 vs. 10%, p = 0.05). There was no significant difference between the groups with regard to proportion of patients with wound leaking problems. CONCLUSION: Both fibrin sealant and intravenous tranexamic acid were effective in reducing blood loss. However, tranexamic acid use reduced post-operative transfusion requirements.

Reverse shoulder arthroplasty - a literature review.

Professor Grammont revolutionised shoulder surgery with his reverse shoulder arthroplasty design. Patients who had poor results from a conventional shoulder replacement because of cuff deficiency can now be treated effectively. Although designed for cuff tear arthropathy, indications continue to evolve and broaden. The initial results look very promising and the implant has gained much popularity over the years. The article provides an extensive literature review of the indications, results and complications for reverse shoulder arthroplasty.

Giant osteochondroma of the talar neck.

Giant osteochondroma is an uncommon entity and it is rare in the foot and ankle region. It is extremely rare to originate from the talus. In this case report we present a case of giant osteochondroma arising from the talar neck measuring 100 mm × 90 mm × 30 mm. It is unique because of the size, site and the age at presentation.

Wrist MRI Arthrogram v Wrist Arthroscopy: What are we Finding?

The aim of the study was to compare the radiological findings of wrist arthrogram with wrist arthroscopy. This allowed us to establish the accuracy (sensitivity, specificity) of MRI arthrogram as a diagnostic tool. Thirty patients (20 female and 10 male) have undergone both wrist MRI arthrogram and wrist arthroscopy over the last 3 years at a District General Hospital. The mean age at arthrogram was 42.4 years with an average 6.7 month interval between the two procedures.The MRI arthrogram was reported by a consultant radiologist with an interest in musculoskeletal imaging and the arthroscopies performed by two upper limb surgeons. Patients who underwent both procedures were identified. The arthrogram reports and operation notes were examined for correlation. Three main areas of pathology were consistently examined: TFCC (triangular fibrocartilage complex), scapholunate and lunotriquetral ligament tears. The sensitivity and specificity of arthrogram was calculated for each. Other areas of pathology were also noted.In the case of TFCC tears MRI arthrogram had 90% sensitivity and 75% specificity. The lunotriquetral ligament examination with this technique was 100% sensitivity and specificity. However for scapholunate ligament tears it only had 91% sensitivity and 88% specificity.Wrist arthrogram and arthroscopy are both invasive techniques. In cost terms the arthrogram remains cheaper but is superseded by arthroscopy as it is both diagnostic and therapeutic.

Unusual recurrence of small cell lung carcinoma.
