Short-term results and complications of the operative treatment of the distal radius fracture AO2R3 C type, planned by using 3D-printed models. Prospective randomized control study.

PURPOSE: 3D-printed models rapidly evolving in orthopaedic. Studies show that 3D-printed models used for preoperative planning improve a better understanding of fracture morphology and reduce operative time, blood loss and frequency of fluoroscopy, but there are no studies that investigated possible advantages in the outcomes and complications for the treatment of distal radius fracture (DRF). Our study aims to evaluate short-term functional results and complications between two groups treated DRF using 3D-printed models for preoperative planning and without. We hypothesize that the addition of 3D-printed models would improve functional outcomes and reduce complication rates. METHODS: 66 randomized cases of DRF AO/OTA C type were enrolled and divided into "Control group" (n = 33) and "3D-printed model group" (n = 33). Personalized 3D-printed models were created. The primary outcomes were: Patient-Rated Wrist Evaluation questionnaire, Quick Disabilities of the Arm, Shoulder and Hand Score questionnaire, and complications. The secondary outcomes were: measurement of the range of motions, grip strength, radiological evaluation, and the visual analogue scale. Assessments were measured at 6 weeks, 3 months, and 6 months intervals. RESULTS: We found that the integration of the 3D-printed model in preoperative planning decreased complication incidence significantly - from 30.3% in the "Control group" to 6.1% in the "3D-printed model group", p = .022. But we did not find a difference in functional and radiological outcomes. CONCLUSION: The 3D-printed models for preoperative planning surgically treating DRF AO/OTA C type can help minimize the complication rate, however, they can't improve functional outcomes in the short-term results. LEVEL OF EVIDENCE: Level I randomized controlled study.

Functional outcomes and quality of life after surgical treatment of spinopelvic dissociation: a case series with one-year follow-up.

BACKGROUND: Spinopelvic dissociation is a transverse sacral fracture in conjunction with a vertical fracture of the sacrum on both sides, which causes the dissociation of the upper sacrum and spine from the pelvis. The most common causes of these fractures are high energy injuries such as falls from height or motor vehicle accidents. Spinopelvic dissociation is rare and heterogenous with severe associated injuries. The aim of this study was to assess the injury characteristics, changes in the quality of life and functional outcomes in the 1-year period after spinopelvic dissociation. MATERIALS AND METHODS: During the period of 4 years (January 2016 and January 2020), 17 patients with spinopelvic dissociation were admitted to our centre and included in this single-centre prospective cohort study. One patient died during the admission; therefore 16 patients were enrolled in the analysis. Patients were followed-up for 12 months. The quality of life changes were evaluated via the SF-36 questionnaire, and the functional outcomes were evaluated using the Majeed pelvic score. Patients completed their questionnaires twice: firstly during hospitalization (regarding their pre-traumatic condition); and once again 1 year after their injury (regarding their current condition). RESULTS: The mean age of the patients was 40.2 ± 17.7 years. Mean Majeed, PCS and MCS scores of SF-36 before the injury were 95.81 ± 9.50, 55.87 ± 8.89, and 43.76 ± 12.45, respectively. Mean Majeed, PCS and MCS scores 1 year after the injury were 71.13 ± 20.98, 43.45 ± 9.64, and 43.41 ± 7.56. During the period of 1 year after the injury, Majeed and PCS results reduced statistically significantly (P = 0.001 and P = 0.003, respectively), while MCS results remained similar (P = 0.501). CONCLUSIONS: According to the data of our study, for patients with spinopelvic dissociation functional outcomes are significantly reduced and only one-third of the patients achieved pre-traumatic functional outcomes 1 year after the injury.

Short-Term Functional Outcomes and Quality of Life after B2.1 Type Pelvic Fractures for Surgically and Non-Surgically Treated Young Patients.

Background and Objectives: Lateral compression injuries of the pelvic ring are most common among young and elderly patients. Of all pelvic ring fracture injuries, the B2.1 type-involving lateral compression of the pelvic ring-is the most common. Despite this, we still have no high-level evidence to consult when choosing between the surgical and non-operative approaches. The purpose of this research was to compare the short-term functional and quality of life outcomes between operatively and non-operatively treated young patients after a B2.1 type pelvic fracture. Materials and Methods: Patients aged 18 to 65 years with pelvic B2.1 type fractures-according to AO/Tile classification-that were hospitalized in a single trauma center between 2016 November and 2019 September were included in the research. Patients were retrospectively divided into two groups regarding their treatment: non-operative and operative. Functional outcomes were evaluated using Majeed score, and SF-36 was used for the evaluation of quality of life. Patients completed these questionnaires twice: first during hospitalization, regarding their pre-traumatic condition (timepoint I); and again 10 weeks after the injury, regarding their current condition (timepoint II). Results: A total of 55 patients (70.6% of whom were female) with type B2.1 pelvic fractures were included in the analysis, with an average age of 37.24 ± 13.78 years. There were 21 (38.18%) patients with high injury severity, and 37 (67.3%) patients were treated operatively versus 18 (32.7%) non-operatively. Between the two timepoints, Majeed score reduced by 34.08 ± 18.95 for operatively and 31.44 ± 14.41 for non-operatively treated patients. For operatively and non-operatively treated patients, the physical component summary (PCS) of the SF-36 questionnaire reduced by 19.45 ± 9.95 and 19.36 ± 7.88, respectively, while the mental component summary (MCS) reduced by 6.38 ± 11.04 and 7.23 ± 10.86, respectively. Conclusions: We observed that operative treatment of B2.1 type pelvic fractures for young patients is not superior to non-operative in the short-term, because the functional outcomes and quality of life are similar in both groups.

Cross-Cultural Adaptation and Psychometric Properties of the Lithuanian Version of the Majeed Pelvic Score.

Background and Objectives: There are no valid patient-based pelvic ring function assessment tools in Lithuania. The most widely used instrument is the Majeed Pelvic Score (MPS), which is proven to be an effective tool for assessing pelvic function after pelvic injuries. The aims of our study were: (1) the translation and cross-cultural adaptation of the MPS for the Lithuanian-speaking population, (2) to test the psychometric properties of the Lithuanian version of the MPS (MPS-LT) at follow-up two-time points after pelvic fractures. Materials and Methods: The MPS was translated and culturally adapted. Psychometric properties of the MPS-LT were determined in one patient group (n = 40) at two time-points during follow-up examination from 1.5 to 3 months (mean 2 months) and from 11 to 20 months (mean 12 months). Results: At the mean time of 2 months after trauma, Cronbach's α of the MPS-LT was 0.65. Correlation of the MPS-LT with the Iowa Pelvic Score (IPS) was r = 0.84 (p < 0.001), and with the Lithuanian SF-36, PCS was r = 0.53 (p < 0.001). At the mean time follow-up of 12 months, Cronbach's α was 0.86, correlation with the IPS was r = 0.92 (p < 0.001), and with the Lithuanian SF-36, PCS - r = 0.82 (p < 0.001). At the 2-month follow-up, neither floor nor ceiling effects were reached, but at 12 months, 27.5% of patients reached the ceiling effect, while none reached the floor effect. The effect size of the MPS-LT was 1.66. Conclusions: The MPS-LT has limited ability to measure functional outcomes at 2 months after pelvic fracture. In contrast, at the 12-month follow-up examination, the MPS-LT had a good ability to assess pelvic function, and it was sensitive to health changes. The MPS-LT can be used as a pelvic function assessment tool after pelvic fractures for the Lithuanian-speaking population.

Comparison of One-Year Functional Outcomes and Quality of Life between Posterior Pelvic Ring Fixation and Combined Anterior-Posterior Pelvic Ring Fixation after Lateral Compression (B2 Type) Pelvic Fracture.

Background and Objectives: The treatment algorithm of lateral compression B2 type pelvic fractures are still under debate. Some authors advocate conservative treatment, while others recommend surgical approach. The clear indications for isolated anterior or posterior ring fixation or combined anterior-posterior pelvic ring fixation of B2 type fractures remain unclear. The aim of this study was to compare the functional outcomes and quality of life after isolated posterior pelvic ring fixation and combined anterior-posterior pelvic ring fixation for the treatment of B2 pelvic fractures. Materials and Methods: Patients aged 18 to 65 years with B2 type pelvic fracture hospitalized in a single trauma centre over a period of 3 years were included in the research. Based on the attending surgeon's preference, patients were treated with isolated posterior or combined anterior-posterior pelvic fixation. The quality of life and pelvic function were assessed using SF-36 and Majeed questionnaires, respectively. Patients filled in the questionnaires twice: during the first hospitalization (concerning their pre-trauma state-timepoint I) and one-year after the injury (timepoint II). Results: A cohort of 32 patients with B2 type pelvic fracture was enrolled in the analysis: 23 (72%) were female and 9 (28%) were male. The mean age was 35.3 ± 11.9 years. In this cohort 13 (41%) patients underwent isolated posterior pelvic ring fixation (group I) and 19 (59%) patients underwent combined anterior-posterior pelvic ring fixation (group II). No statistically significant differences were observed between the groups in both timepoints concerning Majeed, SF-36 PCS and MCS scores. However, in both groups Majeed and SF-36 PCS scores were statistically significantly lower one year after pelvic fracture compared with pre-trauma state, while SF-36 MCS scores did not differ. Conclusions: No differences were found in quality of life and functional outcomes between isolated posterior pelvic ring fixation and combined anterior-posterior fixation for the treatment of B2 type pelvic fractures.

Reciprocal hematogenous osteomyelitis of the femurs caused by Anaerococcus prevotii: A case report.

BACKGROUND: Haematogenous osteomyelitis is an extremely rare disease occurring in adults, especially in developed countries. It is clearly a systemic infection, because bacteraemia spreads over proximal and distal long bones or paravertebral plexuses, resulting in acute or chronic bone infection and destruction. CASE SUMMARY: A 46-year-old Caucasian male was complaining of a left thigh pain. It is known from the anamnesis that the patient developed severe pneumonia three months ago before the onset of these symptoms. The patient was diagnosed with haematogenous osteomyelitis, which developed a turbulent course and required complex combination therapy. The primary pathogen is thought to be Anaerococcus prevotii, which caused pneumonia before the onset of signs of osteomyelitis. Unfortunately, due to the complexity of identifying anaerobes and contributing nosocomial infections, the primary pathogen was not extracted immediately. After the manifestation of this disease, pathological fractures occurred in both femurs, as well as purulent processes in the lungs and molars accompanied. The patient received broad-spectrum antibiotic therapy and countless amounts of orthopaedic and reconstructive surgeries, but no positive effect was observed. The patient underwent osteosynthesis using an Ilizarov's external fixation apparatus, re-fixations, external AO, debridements, intrame-dullary osteosynthesis with a silver-coated intramedullary nail, abscessotomies. The right femur healed completely after the pathological fracture and osteomyelitis did not recur. Left femur could not be saved due to non-healing, knee contracture and bone destruction. After almost three years of struggle, it was decided to amputate the left limb, after which the signs of osteomyelitis no longer appeared. CONCLUSION: To sum it all up, complicated or chronic osteomyelitis requires surgery to remove the infected tissue and bone. Osteomyelitis surgery prevents the infection from spreading further or getting even worse up to such condition that amputation is the only option left.

The one-year mortality rate in elderly patients with osteoporotic fractures of the pelvis.

Osteoporosis is a common condition for elderly people. The incidence of osteoporotic pelvic fractures has been increasing. Osteoporotic pelvic fractures are associated with increased mortality rates. Based on the aim of our study, we found out that one-year mortality rate after a pelvic fracture is high and depends on the fracture type. PURPOSE: The aim of this study was to determine the one-year mortality rate in patients aged 65+ with osteoporotic pelvic fractures depending on the type of fracture according to AO/OTA classification. METHODS: Patients aged 65+ with pelvic insufficiency fractures admitted to a single center between 1 June 2013 and 31 December 2016 were enrolled in the study. The fractures were classified according to AO/OTA classification. The start of the survival time analysis was the date of the injury. The end of the analysis was 31 December 2017 or the date of the patient's death. Mortality rates were assessed with respect to fracture types using Kaplan-Meier curves. The Cox proportional hazards model was applied to assess the dependence of mortality on the fracture type. RESULTS: A total of 105 patients with 95 (90.5%) being female were enrolled in this prospective study. The average age was 80.3 years (95% CI 78.8-81.7). Mean follow-up time was 23.5 months (95% CI 20.7-26.4). According to AO/OTA classification, 30 (28.6%) patients had a type A pelvic fracture, 73 (69.5%) patients-type B fracture, and 2 (1.9%)-type C fracture. Overall, the one-year mortality rate was 23.8% (95% CI 16.8-33.2%). For patients with type A fracture, the one-year mortality rate was 13.3% (95% CI 5.2-31.7%) compared with 27.4% (95% CI 18.6-39.2%) in the group with type B fracture, and this difference was statistically significant (p < 0.001). CONCLUSIONS: We found that within a year after an osteoporotic pelvic fracture, the number of deaths in the patients having type B pelvic fracture was twice higher than in the patients with type A fracture.

Non-anatomic fixation for longstanding traumatic pubic diastasis using a bone graft: A report of two cases.

The incidence of internal fixation failure of symphysis diastasis varies from 6% to 75%. Hardware breakage or migration and symphysis disruption recurrence are often asymptomatic and only in a few cases reoperation is required. This report describes the managements of two cases after failed internal fixation and neglected traumatic symphysis diastasis when it was technically impossible to achieve anatomical reduction of the anterior pelvic ring. Internal fixation and a bone graft for the symphysis without anatomical reposition were performed. Both of the patients achieved good results and had no complaints of pain during daily activities. Restoration of the anatomy should not be the aim in treating recurrence of the symphysis diastasis after failed fixation. The aim of the surgery was static fixation of the anterior pelvic ring with bone grafting.

Different Stabilization Techniques for Type 62B3 Acetabular Fractures in Combination With Primary Total Hip Arthroplasty in Elderly Patients: A Biomechanical Comparison.

INTRODUCTION: The total hip arthroplasty (THA) as part of acute fracture management is used for acetabular fractures in elderly patients. Our objective was to assess the stability of osteosynthesis performed using 2 different techniques in combination with THA in an experimental model. MATERIALS AND METHODS: We conducted 20 experiments using the left-side hemipelves composite bone models. There were 2 testing groups: 1- and 2-stage osteosynthesis. The acetabular fractures of the anterior column and posterior hemitransverse were simulated. The same THA technique was used in both groups. The stability of osteosynthesis was explored and compared between the groups by measuring the fracture displacement of anterior and posterior columns under the standardized test load (1187 N) protocol. Load distance diagrams were generated. RESULTS: The 0.680-mm gap (0.518; 1.548) of the posterior column in the 1-stage group (n = 10) was higher than the 0.370-mm gap (0.255; 0.428) in the 2-stage group (n = 10; P = .002). There was no significant difference between the gap of the anterior column in the 1- and 2-stage groups (0.135 [0.078; 0.290] mm vs 0.160 [0.120; 0.210] mm; P = .579). CONCLUSION: The 2-stage osteosynthesis of the anterior and posterior columns in combination with THA provides better stability of posterior column when compared to 1-stage method in composite bone models.
