Psoas hematoma in the elderly patient, a diagnostic challenge, a case report

Background: A psoas hematoma is an uncommon condition in patients on anticoagulant therapy and patients with bleeding disorders. It can present itself with non-specific symptoms, as anemia, pain and hemodynamically instability. The CT angioscan is the diagnostic test of choice. Case presentation: We report a series of 3 cases of iliopsoas hematoma in older patients. These patients were all on anticoagulant therapy and presented with non-specific symptoms as pain in back or groin, anemia and weakness of the leg. These symptoms could be well explained by other, concurrent diseases. Moreover in one case it was not possible to obtain a reliable history due to cognitive impairment of the patient. In our cases the diagnosis of a psoas hematoma was made after performing many diagnostics or found fortuitously. All three patients recovered well after (temporarily) ceasing of anticoagulant therapy. Discussion: The diagnosis of a psoas hematoma is difficult, especially in elderly patients as illustrated in these cases. The symptoms of a psoas hematoma are often aspecific and can also be explained by other, comorbid diseases. Moreover, elderly patients often have an unusual presentation of illness and the presence of cognitive impairment compromises the reliability of a patients history. It is important to be aware of this diagnosis and perform a CT-scan when a psoas hematoma is possible. Conclusion: A psoas hematoma is easily overlooked in older patients due to an unusual presentation of illness, comorbidity and cognitive impairment

Evidence-based treatment of open ankle fractures

Fractures of the ankle are fairly common injuries. Open ankle fractures are much less common and associated with severe injuries to surrounding tissues. We have performed a systematic review of the literature concerning the clinical results and complication rates in the treatment of open ankle fractures. We conducted a search limited to the following databases: Pubmed/Medline, Cochrane Database of Systematic Reviews, Cochrane Clinical Trial Register and Embase. These were searched from 1968 to April 2010 to identify studies relating to the treatment of open ankle fractures. Fifteen articles concerning 498 patients with treatment of an open ankle fracture were identified. The number of included patients varied from 11 to 64. There were 2 prospective and 13 retrospective studies. All articles were case series and classified as Level IV evidence. In 373 cases, open ankle fractures were treated by immediate internal fixation. In 125 cases, a conservative treatment or delayed/other fixation treatment was followed. Of those patients treated by immediate internal fixation, 81% had satisfactory result. Poor results (15%) were most commonly due to non-anatomic reductions, articular surface damage or deep infection. When conservative treatment was followed, 76% had satisfactory results. The most reported complications after immediate internal fixation were deep infection (8%) and skin necrosis (14%). There is a lack of high quality literature concerning the (operative) treatment of patients with open ankle fractures. Remarkable is that most authors reported satisfactory results after performance of their treatment protocol. Based on the available literature, we formulated guidelines regarding: timing of operative treatment, wound irrigation, the role of internal fixation, wound coverage and closure, the use of antibiotics and additional therapies

Operative aspects of the syndesmotic screw: Review of current concepts

The distal tibiofibular syndesmosis is important for stability of the ankle mortise and thus for weight transmission and walking. Syndesmotic injuries are most commonly associated with fibular fractures, but they can also occur in isolation or with damage to the lateral ankle ligament after traumatic supination. The need for trans-syndesmotic fixation of the distal tibiofibular joint has been controversial. The goat of this review was to collect evidence on the technical aspects of performing an osteosynthesis using a syndesmotic screw and to formulate some recommendations for clinical practice.

Functional Outcome After Nonoperative Management of Tibial Plateau Fractures in Skeletally Mature Patients: What Sizes of Gaps and Stepoffs Can be Accepted?

BACKGROUND: Gap and stepoff measurements provide information about fracture displacement and are used for clinical decision-making when choosing either operative or nonoperative management of tibial plateau fractures. However, there is no consensus about the maximum size of gaps and stepoffs on CT images and their relation to functional outcome in skeletally mature patients with tibial plateau fractures who were treated without surgery. Because this is important for patient counseling regarding treatment and prognosis, it is critical to identify the limits of gaps and stepoffs that are well tolerated. QUESTIONS/PURPOSES: (1) In patients treated nonoperatively for tibial plateau fractures, what is the association between initial fracture displacement, as measured by gaps and stepoffs at the articular surface on a CT image, and functional outcome? (2) What is the survivorship of the native joint, free from conversion to a total knee prosthesis, among patients with tibial plateau fractures who were treated without surgery? METHODS: A multicenter cross-sectional study was performed in all patients who were treated nonoperatively for a tibial plateau fracture between 2003 and 2018 in four trauma centers. All patients had a diagnostic CT scan, and a gap and/or stepoff more than 2 mm was an indication for recommending surgery. Some patients with gaps and/or stepoffs exceeding 2 mm might not have had surgery based on shared decision-making. Between 2003 and 2018, 530 patients were treated nonoperatively for tibial plateau fractures, of which 45 had died at follow-up, 30 were younger than 18 years at the time of injury, and 10 had isolated tibial eminence avulsions, leaving 445 patients for follow-up analysis. All patients were asked to complete the validated Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire consisting of five subscales: symptoms, pain, activities of daily living (ADL), function in sports and recreation, and knee-related quality of life (QOL). The score for each subscale ranged from 0 to 100, with higher scores indicating better function. A total of 46% (203 of 445) of patients participated at a mean follow-up of 6 ± 3 years since injury. All knee radiographs and CT images were reassessed, fractures were classified, and gap and stepoff measurements were taken. Nonresponders did not differ much from responders in terms of age (53 ± 16 years versus 54 ± 20 years; p = 0.89), gender (70% [142 of 203] women versus 59% [142 of 242] women; p = 0.01), fracture classifications (Schatzker types and three-column concept), gaps (2.1 ± 1.3 mm versus 1.7 ± 1.6 mm; p = 0.02), and stepoffs (2.1 ± 2.2 mm versus 1.9 ± 1.7 mm; p = 0.13). In our study population, the mean gap was 2.1 ± 1.3 mm and stepoff was 2.1 ± 2.2 mm. The participating patients divided into groups with increasing fracture displacement based on gap and/or stepoff ( 4 mm), as measured on CT images. ANOVA was used to assess whether an increase in the initial fracture displacement was associated with poorer functional outcome. We estimated the survivorship of the knee free from conversion to total knee prosthesis at a mean follow-up of 5 years using a Kaplan-Meier survivorship estimator. RESULTS: KOOS scores in patients with a less than 2 mm, 2 to 4 mm, or greater than 4 mm gap did not differ (symptoms: 83 versus 83 versus 82; p = 0.98, pain: 85 versus 83 versus 86; p = 0.69, ADL: 87 versus 84 versus 89; p = 0.44, sport: 65 versus 64 versus 66; p = 0.95, QOL: 70 versus 71 versus 74; p = 0.85). The KOOS scores in patients with a less than 2 mm, 2 to 4 mm, or greater than 4 mm stepoff did not differ (symptoms: 84 versus 83 versus 77; p = 0.32, pain: 85 versus 85 versus 81; p = 0.66, ADL: 86 versus 87 versus 82; p = 0.54, sport: 65 versus 68 versus 56; p = 0.43, QOL: 71 versus 73 versus 61; p = 0.19). Survivorship of the knee free from conversion to total knee prosthesis at mean follow-up of 5 years was 97% (95% CI 94% to 99%). CONCLUSION: Patients with minimally displaced tibial plateau fractures who opt for nonoperative fracture treatment should be told that fracture gaps or stepoffs up to 4 mm, as measured on CT images, could result in good functional outcome. Therefore, the arbitrary 2-mm limit of gaps and stepoffs for tibial plateau fractures could be revisited. The survivorship of the native knee free from conversion to a total knee prosthesis was high. Large prospective cohort studies with high response rates are needed to learn more about the relationship between the degree of fracture displacement and functional recovery after tibial plateau fractures.
