Clinical and radiographic outcome of tension band suture fixation for displaced olecranon fractures.

BACKGROUND: Tension band wire fixation (TBW) is a well-described method for treating displaced olecranon fractures. Further surgery is often needed due to wound breakdown or prominent hardware. An all-suture technique has recently been described as an alternative to TBW but radiographic and clinical outcome are not well established. The aim of this single-center retrospective cohort study was to evaluate outcome after treatment with all-suture technique for simple displaced olecranon fractures. METHODS: A retrospective review of olecranon fractures in patients (> 18 years) treated for displaced olecranon fractures with tension band suture fixation (TBSF) between February and August 2019 was performed in our facility. Primary outcome was revision surgery, which was assessed four years after surgery. Clinical and radiographical follow-up was performed at two weeks, six weeks, three months and six months to assess union rate, fracture displacement, range of motion (ROM), Quick-DASH and Oxford Elbow Score. RESULTS: A total of 24 patients were included. Median age was 64 years [IQR:39-73], 9 patients were male and median ASA score was 2 [IQR:1-2]. 15 fractures were Mayo type 2 A and 9 type 2B with minor comminution. At four-year follow-up, three patients had died. None of the remaining 21 patients had undergone revision surgery. At six months, the median Quick-DASH and Oxford Elbow Score were 2.3 [IQR:0-4.5] and 47 [IQR:46-48], respectively. Median elbow extension and flexion deficits were 0° [IQR:0-2.25] and 0° [IQR:0-0], respectively. Radiographic union was achieved in all patients. In two cases radiographic loss of reduction and malunion was observed but both patients were asymptomatic and had no functional deficits. One patient refractured the elbow due to a second trauma and was reoperated. CONCLUSIONS: TBSF is a promising technique for Mayo type 2 A and 2B fractures with minor comminution. There were no revision surgeries within the first four years. We found good functional outcomes and a high union rate.

Completeness and validity of the Danish fracture database.

OBJECTIVE: To calculate completeness of the Danish Fracture Database (DFDB) overall and stratified by hospital volume and to calculate the validity of independently assessed variables in the DFDB. STUDY DESIGN AND SETTING: In this completeness and validation study, cases registered in the DFDB with fracture-related surgery in 2016 were retrospectively reviewed. All cases had undergone fracture-related surgery at a Danish hospital reporting to the DFDB in 2016. The Danish health care system is fully tax-funded providing equal and free access to all residents. Completeness was calculated as sensitivity and validity was calculated as positive predictive values (PPVs). RESULTS: OVERALL COMPLETENESS WAS 55.4% (95% CI: : 54.7-56.0). For small-volume hospitals it was 60% (95% CI: 58.9-61.1), and for large-volume hospitals, it was 52.9% (95% CI: 52.0-53.7). The PPV for variables of interest ranged from 81% to 100%. The PPV of key variables was 98% (95% CI: 95-98) for operated side, 98% (95% CI: 96-98) for date of surgery, and 98% (95% CI: 98-100) for surgery type. CONCLUSION: We found low completeness of data reported to the DFDB in 2016; however, in the same period, the validity of data in the DFDB was high.

Surgical treatment of displaced isolated lateral malleolar fractures: incidence of adverse events requiring revision: a retrospective cohort study.

BACKGROUND: Recent systematic reviews support that non-operative management should be the standard treatment for all stable isolated lateral malleolar fractures (ILMFs), regardless of fibular fracture displacement. Surgical fixation of ILMFs carries a risk of adverse events (AEs), and many patients will later require implant removal. We wanted to estimate the incidence of AEs requiring revision after surgical fixation of "potentially stable" displaced ILMFs before non-operative treatment became standard care in our department. MATERIALS AND METHODS: To identify patients with "potentially stable" ILMFs who had been treated surgically in a historical cohort, we retrospectively applied the stability-based classification system, introduced by Michelson et al., to a cohort of 1006 patients with ankle fractures treated surgically from 2011 to 2016. The primary outcome of this retrospective cohort study was the incidence of AEs that had functionally significant adverse effects on outcome and required revision in the first 12 months after surgery. AEs were graded and categorized using the Orthopedic Surgical Adverse Events Severity (OrthoSAVES) System. RESULTS: The study population comprised 108 patients with "potentially stable" displaced ILMFs; 4 patients (3.7% [95% CI (0.1-7.3%]) experienced AEs requiring revision in the first twelve months after surgery. There were 5 additional patients (4.6%) with functionally significant AEs where revision surgery was not indicated within the first twelve months after surgical fixation. A further 5 patients (4.6%) had AEs managed in the outpatient clinic (grade II); 36 patients (33.3%) required secondary implant removal due to implant-related discomfort. CONCLUSIONS: Surgical fixation of ILMFs carries a risk of severe AEs, and many patients will subsequently need implant-removal procedures. Further prospective studies are required to ascertain whether non-operative treatment can lower the risk of AEs and the need for additional surgical procedures.

The Noergaard technique is a non-traumatic method for reduction of anterior shoulder dislocation.

INTRODUCTION: In this article, we describe the Noergaard technique for reduction of anterior shoulder dislocation. This is an atraumatic reduction method proven successful through several years of practice. We describe and evaluate the results of this technique through a retrospective analysis of patients admitted and treated for anterior shoulder dislocation at the emergency department (ED) of Hvidovre Hospital, Denmark, in a one-year period. METHODS: We reviewed the charts of all patients admitted with anterior shoulder dislocation (n = 151) at the ED. In the Noergaard technique, the patient is placed standing, bent over forwards in front of the rail on a hospital bed, resting the forehead on the back of the non-affected forearm, which is placed on the rail. The affected arm should now be relaxed and stretched, hanging straight down towards the floor. The patient is then instructed to relax as much as possible and make pendular and circular motions with the affected arm hanging down. RESULTS: Reduction was primarily attempted in 67 patients using the Noergaard technique. Successful reduction was achieved in a total of 52 patients (77%). CONCLUSIONS: The Noergaard technique seems to be a safe and atraumatic reduction technique that involves no physical manipulation of the affected limb. Based on our results and experience, we recommend the use of this technique as first line of treatment in anterior shoulder dislocations. FUNDING: none. TRIAL REGISTRATION: The study was registered with www.clinicaltrials.gov (NCT03649373).

20-year trends of distal femoral, patellar, and proximal tibial fractures: a Danish nationwide cohort study of 60,823 patients.

Background and purpose - Knee fracture treatment burden remains unknown, impeding proper use of hospital resources. We examined 20-year trends in incidence rates (IRs) and patient-, fracture-, and treatment-related characteristics of knee fracture patients.Patients and methods - This nationwide cohort study of prospectively collected data including patients with distal femoral, patellar, and proximal tibial fractures from the Danish National Patient Registry during 1998-2017, assesses IRs of knee fractures (per 105 inhabitants) as well as patient-, fracture-, and treatment-related characteristics of knee fracture patients.Results - During 1998-2017, 60,823 patients (median age 55; 57% female) sustained 74,106 knee fractures. 74% of the study population had a Charlson Comorbidity Index (CCI) of 0 and 18% a CCI of ≥ 2. 51% were proximal tibial fractures, 31% patellar fractures, and 18% distal femoral fractures. At the time of knee fracture, 20% patients had concomitant near-knee fractures (femur/tibia/fibula shaft/hip/ankle), 13% concomitant fractures (pelvic/spine/thorax/upper extremities), 5% osteoporosis, and 4% primary knee osteoarthritis. Over 1/3 knee fractures were surgically treated and of these 86% were open-reduction internal fixations, 9% external fixations, and 5% knee arthroplasties. The most common surgery type was proximal tibia plating (n = 4,868; 60% female). Knee fracture IR increased 12% to 70, females aged > 51 had the highest knee fracture IR, proximal tibial fracture had the highest knee fracture type IR (32) and surgically treated knee fracture IR increased 35% to 23.Interpretation - Knee fracture IRs, especially of surgically treated knee fractures, are increasing and proximal tibial fracture has the highest knee fracture type IR. Females aged > 51 and patients with comorbidity are associated with knee fracture, proximal tibial fracture, proximal tibial fracture surgery, and posttraumatic knee arthroplasty.

Knee pain and associated complications after intramedullary nailing of tibial shaft fracture.

INTRODUCTION: The treatment of choice for unstable diaphyseal fractures in the tibia is reamed insertion of an intramedullary nail (IMN). The most common complication to this treatment is chronic knee pain with reported rates ranging from 10% to 87% with a mean of 47.4% in meta-analyses. METHODS: This study evaluates the long-term outcome after IMN insertion in adult patients with a tibial shaft fracture using the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. The study includes patients operated on one of five Danish hospitals in a five-year period. The patients received a KOOS questionnaire with questions regarding knee-specific symptoms, stiffness, pain, function and quality of life. Data were subsequently compared to those of a reference population. RESULTS: A total of 391 patients were enrolled from the trauma centre's database search. 55 patients did not meet the inclusion criteria. Questionnaires were sent out to 336 patients and 223 (66%) responded. Mean age was 47.9 years at the time of surgery; 63% were men. The follow-up time ranged from 1.7 to 6.7 years. CONCLUSIONS: With a follow-up time of more than six years after receiving an IMN, patients in this study experienced more knee-specific symptoms, pain, limitations in sports and daily living than a reference population who had not undergone surgery. The study population also reported poorer quality of life outcomes than the reference population. FUNDING: none. TRIAL REGISTRATION: Approved by the Danish Data Protection Agency. Clinical trials: NCT03649360.

[Patients in need for major lower extremity amputations are a challenge]. / Den amputationstruede patient er en udfordring for sundhedsvæsenet.

Major lower extremity amputations based on end-stage chronic leg ischaemia or diabetic ulcers with infection are relatively common orthopaedic procedures. Patients are usually evaluated for the possibility of lower extremity revascularisation. Those who are not fit for vascular surgery are transferred to an orthopaedic department for amputation. These patients are a big challenge as they are by definition multi-morbid individuals, who have to undergo major surgery. The high mortality rate in this population warrants new approaches, including optimised multidisciplinary regimes.

[Overlooked spin-out phenomenon as the course of pain in a patient with a mobile-bearing total knee arthroplasty]. / Overset spin-out-fænomen som årsag til kroniske smerter hos patient med totalknæalloplastik.

We present a case of a 66-year-old woman who had a total knee arthroplasty. Shortly after surgery a 90° rotation of her polyethylene liner took place. The complication was undiagnosed for 1.5 years. To know this problem and be able to diagnose it is crucial for doctors, who come in contact with patients who have had a total knee arthroplasty.

[Tranexamic acid reduces blood loss after major elective orthopaedic operations]. / Tranexamsyre reducerer blodtabet efter større elektive ortopædkirurgiske operationer.

Anaemia in surgical patients has been proven to increase morbidity and mortality. Due to the risk of adverse effects and the cost of blood transfusions it is important to reduce the need for transfusions by pre- and intra-operative interventions. Tranexamic acid has long been used in orthopaedic surgery as an antifibrinolytic agent. Several studies within the orthopaedic fields have underlined the effect of the drug in reducing blood loss and need for transfusions. However, more studies are needed to examine the optimal dosage and administration along with the risks associated with the drug.
