RESUMO

PURPOSE OF THE STUDY The prevalence of nerve structure injuries accompanying pelvic and acetabular fractures is stated to be 5-25 %, with most frequent injuries to motor nerve structures associated with fractures of the posterior wall of the acetabulum. Prognostically worse outcomes of regeneration are documented mainly in iatrogenic, intraoperative injuries to nerve structures. This study aims to document the functional effect of muscle transfers restoring the movement of lower extremities with irreversible nerve lesion caused by the pelvic and acetabular fracture. MATERIAL AND METHODS A total of 18 patients with irreversible palsy of lower extremities in L4-S1 segments underwent a reconstruction surgery in the period 2006-2016, of whom 13 patients with the mean age of 42 (21-79) years arrived for a follow-up. The group included 10 patients with the loss of function of peroneal portion of the sciatic nerve, one patient sustained femoral nerve lesion and two patients suffered complete sciatic nerve lesion (both the peroneal and tibial portion). The patients were evaluated at the average follow-up of 77 (24-129) months after the reconstruction surgery. The average time interval from pelvic fracture to reconstruction by muscle transfer was 47 (18-151) months. Due to a wide spectrum of functional damage, the patients were evaluated in terms of the overall effect of the reconstruction surgery on the activities of daily living using the LEFS (The Lower Extremity Functional Scale). The surgical techniques used transposition of tensor fascie latae for femoral nerve lesion, transposition of tibialis posteriormuscle for palsy of the peroneal division of the sciatic nerve and tenodesis of tibialis anterior tendon and peroneus longustendon for the palsy of the peroneal and tibial portion of sciatic nerve. RESULTS The effect of movement restoration on daily living evaluated using the LEFS achieved 65 points (53-79) which is 85% of the average value of LEFS in healthy population. The transposition of active muscles tibialis posterior and tensor fasciae latae resulted in all the patients in active movement restoration. A loss of correction of foot position following the performed tenodesis of the paralysed tibialis anterior muscle was observed in one patient, with no significant impact on function. No infection complication was reported in the group. In 78% of patients the intervention was performed as day surgery. DISCUSSION There is a better prognosis for restoration in incomplete nerve lesion than in complete lesions and also in the loss of sensation than in the loss of motor function. The mini-invasive stabilisation of pelvic ring according to literature does not increase the risk of nerve lesions, while on the other hand a higher incidence of femoral nerve damage by INFIX fixator is documented. The type of muscle transfer is selected based on the availability of active muscles suitable for transposition and also with respect to functional requirements of the patient. CONCLUSIONS Irreversible palsy of lower extremity after the pelvic fracture is easily manageable as to the restoration of function. Surgical interventions using the preserved active muscles to restore the lost movement should be a component part of comprehensive surgical care for patients who sustained a pelvic fracture and should be performed centrally at a centre availing of comprehensive expertise. Key words: nerve lesion, tendon transfer, acetabulum, pelvis, fracture.

RESUMO

With the serious aging of the population, the incidence of fragility fractures of the pelvis(FFPs) has gradually increased, which has become a public problem affecting the living quality of the elderly. When a surgical treatment is chosen, the procedure should be as minimal invasive as possible and avoid all surgical complications. In recent years, different techniques for percutaneous or less invasive fixation of the posterior pelvic ring have been developed. Their advantages and limitations are presented: sacroplasty, iliosacral screw osteosynthesis, cement augmentation, transiliac internal fixation, transsacral osteosynthesis, lumbopelvic fixation. The purpose of this paper is to review the classification and minimally invasive treatment of FFP.

RESUMO

AIMS: The aim of this study was to report the outcomes of patients who underwent definitive surgery for secondary chondrosarcomas arising from osteochondromas. PATIENTS AND METHODS: A total of 51 patients with secondary chondrosarcomas occurring from osteochondromas were reviewed. Median age was 36 years (interquartile range (IQR) 15 to 82). Median follow-up was 6.9 years (IQR 2.8 to 10.6). The pelvis was the most commonly affected site (59%). Histological grades were grade I in 35 (69%), grade II in 13 (25%), and grade III in three patients (6%). RESULTS: Preoperative biopsy histology correctly predicted the final histological grade in 27% of patients. The ten-year disease-specific survival (DSS) for all patients was 89.4%. Local recurrence occurred in 15 patients (29%), more commonly in pelvic tumours (37%) compared with limb tumours (19%). Four patients with pelvic tumours died from progression of local recurrence. No patient with limb tumours died of disease. Wide/radical margin was associated with improved local recurrence-free survival (p = 0.032) and local recurrence was associated with worse DSS (p = 0.005). CONCLUSION: We recommend that a secondary chondrosarcoma arising from osteochondroma of the pelvis is resected with wide/radical resection margins. The balance between the morbidity of surgery and risk of local recurrence needs to be considered in patients with limb secondary chondrosarcomas.

RESUMO

RATIONALE: Obturator dislocation of the femoral head combined with ipsilateral femoral neck and pubic fracture is a rare injury. We used cannulated screws combined with a femoral neck medial plate for the first time to treat this type of injury and achieved good follow-up results. PATIENT CONCERNS: The patient was hospitalized due to an accident resulting in swelling and deformity accompanied by limited mobility of the right hip and left knee. DIAGNOSES: X-ray examination and computed tomography confirmed that the patient suffered from right hip obturator dislocation, femoral head and neck fracture, pubic fracture, as well as open fracture of the left femoral shaft. INTERVENTIONS: Open reduction and internal fixation with cannulated screws and a medial support plate of the femoral neck were performed for the right hip obturator dislocation, femoral head and neck fracture, and the pubic fracture. Artificial bone grafting was performed to support the femoral head defect. Debridement and the second phase of internal fixation were executed to cure the open fracture of the left femoral shaft. OUTCOMES: The patient was followed-up for 6 months and showed good hip function. X-ray examination and computed tomography indicated that the fractures healed well without fracture displacement or loosening of the implants. Meanwhile, there were no signs of femoral neck valgus and femoral head necrosis observed. LESSONS: The combination of cannulated screws and medial support plate was suggested for the treatment of hip obturator dislocation and femoral head and neck fracture. Furthermore, partial weight loading exercise should be performed promptly to reduce the risk of muscular atrophy and myasthenia.

RESUMO

Objective: To explore the application of individualized transiliac crest nail-grafting guide plate prepared by computer-aided design and three-dimensional (3D) printing technology in deep pelvic external fixator implantation. Methods: Five patients with pelvic fractures were collected between May 2017 and February 2018. There were 4 females and 1 male with an average age of 52 years (range, 29-68 years). Pelvic fractures were classified as type B in 3 cases and type C in 2 cases by Tile classification. The interval between injury and operation was 6-14 days (mean, 9 days). The preoperative CT images of pelvic fractures were collected. The data was reconstructed by 3D imaging reconstruction workstation. An individualized transiliac crest nail-grafting guide plate was designed on the virtual 3D model. The individualized transiliac crest nail-grafting guide plate and the solid pelvic model were produced with the 3D printing technology. The individualized transiliac crest nail-grafting guide plate was used for intraoperative deep pin position on iliac crest after the preoperative simulation. The follow-up CT scans were used to determine the differences in distance from anterior superior iliac spine, convergence angle, and caudal angle between the preoperative plan and postoperative measurement. Results: During the operation, the individualized transiliac crest nail-grafting guide plate was used to guide the placement of 20 pins. X-ray film and CT examination showed that all pins were well positioned. The average depth of pins was 83.16 mm (range, 70.13-100.53 mm). Fitted 3D reconstruction images showed that the entry point and orientation of the pins were all consistent with preoperative schemes. Compared with the planned nail path, there was no significant difference in the distance from anterior superior iliac spine, convergence angle, and caudal angle in the actual nail path ( P>0.05). No loosening and rupture of pin, no damage of blood vessels and nerve, and shallow or deep infection occurred during 3 months follow-up, and the incisions healed by first intention. All patients were satisfied with the treatment process. The ranges of motion of hip and knee were normal, and the visual analogue scale (VAS) score was 0-3 (mean, 0.5). Conclusion: The individualized transiliac crest nail-grafting guide plate technique is the improvement of traditional technique. It can increase accuracy and effective depth of pin position, enable patients to obtain pelvic mechanical stability quickly after operation, and reduce the risk of complications related to nail path.

RESUMO

BACKGROUND: Hemipelvectomy is an important technique for the treatment of pelvic sarcomas. OBJECTIVES: Presentation of the technical overview, as well as surgical and oncological outcomes of sarcoma patients treated with pelvic tumor resections and treatment recommendations. METHODS: Retrospective analysis of 160 patients treated by pelvic tumor resection for chondrosarcoma between 1977 and 2014. RESULTS: Chondrosarcoma was the most common diagnosis leading to pelvic tumor resection in this collective (38%). The mean patient age at operation was 49 years. 44 patients were treated for G1, 83 patients for G2 and 33 patients for G3 or dedifferentiated chondrosarcoma. The mean tumor diameter was ≥10 cm in 76.1% of cases. Limb salvaging operations were possible in 82.5% of patients. The most common reconstruction technique was hip transposition (38.7%). Clear resection margins were achieved in 86.9% (R0). Local recurrence was observed in 22.5%. Distant pulmonal metastasis was diagnosed in 25% of patients. Grading-specific survival was 81.8% for G1, 59% for G2 and 24.2% for G3 or dedifferentiated chondrosarcoma with a mean survival of 84.4, 89 and 69.4 months respectively. CONCLUSIONS: Pelvic tumor resection with clear margins is the most important known positive predictive local factor affecting overall outcomes, in addition to uncontrollable factors such as grading and tumor size. Defect reconstruction depends on multiple factors such as patient age and adjuvant therapy. The stage of the disease has the greatest impact on overall survival rates and should be considered when contemplating pelvic tumor resections in sarcoma patients.

RESUMO

PURPOSE: The purpose of this study was to clarify which local treatment is oncologically and functionally effective in pelvic Ewing sarcoma (ES). METHODS: A consecutive series of patients who underwent pelvic resections and acetabular reconstructions after chemotherapy between 1986 and 2016 at a supra-regional center were evaluated. RESULTS: The cohort consisted of 35 patients. The 5-year overall survival (OS) and local recurrence-free survival (LRFS) was 61% and 72%, respectively. Preoperative radiotherapy (RT) and surgery provided an excellent/good histological response in 92% and achieved significantly better OS (5 years, 64%) and LRFS (5 years, 100%) than surgery alone or surgery with postoperative RT. The Musculoskeletal Tumor Society functional scores were significantly better in patients with hip transposition than those with structural reconstructions (74% vs 57%; P = .031) using custom-made prostheses, irradiated autografts, and ice-cream cone prostheses. These scores were significantly lower if patients had deep infection (P = .035), which was the most common complication (28%) in structural reconstructions but did not occur in hip transposition even when performed after preoperative RT. CONCLUSION: Acetabular reconstruction with hip transposition resulted in no deep infection and superior function in patients with pelvic ES even when combined with preoperative RT, which improved tumor necrosis and rate of local control and survival.

RESUMO

The author presents a case study of the use of resuscitative endovascular balloon occlusion (REBOA) as a suitable alternative to thoracotomy and clamping of the descending aorta to control retroperitoneal bleeding in a patient with a pelvic injury. The patient who suffered multiple trauma after car accident, type C pelvic injury and retroperitoneal bleeding among other things, was following the pre-hospital ambulance care transported to the department of emergency medicine, with catecholamine infusion to support the blood flow. After the primary survey following the ATLS principles, the patient was taken for a CT scan. The CT examination revealed also multiple sources of retroperitoneal bleeding. Subsequently, the patient was brought to the operating room, where endovascular balloon occlusion of the descending aorta was performed to temporarily control retroperitoneal bleeding, which provided more time to treat the patient in line with the damage control surgery principles. In bleeding patients who suffered blunt torso traumas and serious haemorrhagic shock, or patients "in extremis", the survival after emergency thoracotomy ranges only around 1%. The to date results of REBOA technique applied in same indications are very promising globally. The survival rate increases multiple times especially in hypotensive patients, without the necessity of their immediate cardiopulmonary resuscitation. Key words:resuscitative balloon occlusion of the aorta, REBOA, haemorrhagic shock, retroperitoneal bleeding.

RESUMO

There remains confusion in the literature with regard to the spinopelvic relationship, and its contribution to ideal acetabular component position. Critical assessment of the literature has been limited by use of conflicting terminology and definitions of new concepts that further confuse the topic. In 2017, the concept of a Hip-Spine Workgroup was created with the first meeting held at the American Academy of Orthopedic Surgeons Annual Meeting in 2018. The goal of this workgroup was to first help standardize terminology across the literature so that as a topic, multiple groups could produce literature that is immediately understandable and applicable. This consensus review from the Hip-Spine Workgroup aims to simplify the spinopelvic relationship, offer hip surgeons a concise summary of available literature, and select common terminology approved by both hip surgeons and spine surgeons for future research.

RESUMO

AIMS: The aim of this study was to describe the use of 3D-printed sacral endoprostheses to reconstruct the pelvic ring and re-establish spinopelvic stability after total en bloc sacrectomy (TES) and to review its outcome. PATIENTS AND METHODS: We retrospectively reviewed 32 patients who underwent TES in our hospital between January 2015 and December 2017. We divided the patients into three groups on the basis of the method of reconstruction: an endoprosthesis group (n = 10); a combined reconstruction group (n = 14), who underwent non-endoprosthetic combined reconstruction, including anterior spinal column fixation; and a spinopelvic fixation (SPF) group (n = 8), who underwent only SPF. Spinopelvic stability, implant survival (IS), intraoperative haemorrhage rate, and perioperative complication rate in the endoprosthesis group were documented and compared with those of other two groups. RESULTS: The mean overall follow-up was 22.1 months (9 to 44). In the endoprosthesis group, the mean intraoperative hemorrhage was 3530 ml (1600 to 8100). Perioperative complications occurred in two patients; both had problems with wound healing. After a mean follow-up of 17.7 months (12 to 38), 9/10 patients could walk without aids and 8/10 patients were not using analgesics. Imaging evidence of implant failure was found in three patients, all of whom had breakage of screws and/or rods. Only one of these, who had a local recurrence, underwent re-operation, at which solid bone-endoprosthetic osseointegration was found. The mean IS using re-operation as the endpoint was 32.5 months (95% confidence interval 23.2 to 41.8). Compared with the other two groups, the endoprosthesis group had significantly better spinopelvic stability and IS with no greater intraoperative haemorrhage or perioperative complications. CONCLUSION: The use of 3D-printed endoprostheses for reconstruction after TES provides reliable spinopelvic stability and IS by facilitating osseointegration at the bone-implant interfaces, with acceptable levels of haemorrhage and complications.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the reliability of fracture location and horse sporting discipline as prognostic indicators after a pelvic fracture in a referral centre caseload. MATERIALS AND METHODS: Data were collected for the short- and long-term follow-up of all cases with a diagnosis of pelvic fracture in a 7-year period. Information was obtained for 75 horses through a postal and internet survey. The proportion of horses returning to competition following fractures was compared between groups according to the competition discipline and the characteristics of the fracture. RESULTS: Forty-six of 75 horses returned to or began their intended activity. This proportion was significantly lower in the group of horses that sustained a comminuted fracture irrespective of the fracture location (11/25, p = 0.05). The proportion of Standardbred trotter racehorses returning to a sporting career after pelvic fracture (9/20) was not significantly different from horses competing in other disciplines (37/55). Cases of multiple pelvic fractures in the study population, and particularly those involving the acetabulum, had the worst sports prognosis (2/8 and 0/4). Nevertheless, two foals and one yearling (3/5) with isolated fracture of the acetabulum went on to race. CLINICAL SIGNIFICANCE: A clear characterization of the fracture is essential for prognosis, as comminuted fractures seem to entail a poorer athletic prognosis. Despite a lack of significance, prognosis seems poorer for Standardbred trotter racehorses and for cases with acetabulum involvement in multiple fractures. These results should be confirmed in larger samples.

RESUMO

Abstract: Objective To analyze the relationship between the number of pelvic ring fractures, the location of fracture and Tile type of pelvic fracture and pelvic fracture healing status. To discuss how to understand the pelvic malunion, severe pelvic malunion and bony pelvis deformity (destruction) in Classification of the Impairment Related to Injury. Methods One hundred and ninety-eight cases of evaluation of body impairment class of pelvic fracture caused by traffic accident accepted by Zhongcheng Institute of Forensic Science in 2016 were collected. The cases were statistically analyzed in terms of the distribution of the number of pelvic ring fracture, the location of pelvic ring fracture and Tile type of pelvic fracture in various healing statuses. Results There were 16 cases without pelvic ring fracture, 18 cases of single pelvic ring fracture, 91 cases of 2 pelvic ring fractures, 73 cases of 3 or more pelvic ring fractures, 136 cases of anterior or posterior pelvic ring fractures, 46 cases of simultaneous anterior and posterior ring fractures. There were 34 cases of Tile A type, 130 cases of Tile B type and 24 cases of Tile C type. Statistical analysis results showed that, the differences in distribution of the number of pelvic ring fracture, the location of pelvic ring fracture and Tile type of pelvic ring fracture in various healing statuses had statistical significance (P<0.05). Conclusion In determination of the healing status of pelvic fracture, preliminary judgment can be made by using the number of pelvic ring fracture, status of pelvic ring fracture and Tile type of pelvic fracture. Caution is required when dealing with single pelvic fractures (including dislocations), and determining the destruction of bony pelvis.

RESUMO

OBJECTIVE: To compare distraction index (DI) with hip arthroscopy findings in juvenile dogs with hip dysplasia undergoing unilateral or bilateral double pelvic osteotomy (DPO). STUDY DESIGN: Retrospective case series. ANIMALS: Twenty dogs (36 hip joints). METHODS: Medical records from dogs undergoing unilateral or bilateral DPO (2011-2016) were reviewed. Distraction index was measured by using distraction view radiographs. Arthroscopic images were analyzed. Cartilage was graded by using the modified Outerbridge scale (0 = arthroscopically normal, 1 = chondromalacia, 2 = surface fibrillation, 3 = deep fissuring, 4 = full-thickness cartilage loss, and 5 = eburnation of exposed subchondral bone). Dorsal acetabular rim, acetabular labrum, the ligament of head of the femur, and synovitis were graded by using a four-point scale (normal, mild, moderate, severe). Spearman and Pearson correlations were used to compare DI between grade groups and age. RESULTS: Distraction index ranged from 0.4 to 1.0 (mean 0.69 ± 0.16). Most of the hips had an arthroscopically normal femoral head and acetabulum in most regions, except for the region at the insertion of the ligament of the head of the femur. There was a low positive correlation between synovitis and DI (Spearman ρ = 0.35, P = .0346). No other differences in DI were identified between grade or age groups. CONCLUSION: There was a low positive correlation between synovitis and DI. No other differences in DI were identified. CLINICAL SIGNIFICANCE: Arthroscopic evaluation of the coxofemoral joint prior to DPO can allow detection of joint pathology that might not be appreciated by using traditional radiographic screening criteria.

RESUMO

Introduction: While transcatheter arterial embolization (TAE) is an effective way to control arterial bleeding associated with pelvic fracture, delayed TAE may increase mortality risk. The purpose of the current study was to determine how time to TAE affects outcomes in patients with pelvic fracture in the emergency department. Methods: From January 2014 to December 2016, the trauma registry and medical records of patients with pelvic fracture who underwent TAE were retrospectively reviewed. The relationship between the time to TAE and patient outcomes was evaluated. The characteristics of surviving and deceased patients were also compared to search for prognostic factors affecting survival. Results: Eighty-four patients were enrolled in the current study. Among patients with pelvic fracture who underwent TAE, the overall mortality rate was 16.7%. There were positive relationships between the time to TAE and the requirement for blood transfusion and between the time to TAE and intensive care unit (ICU) length of stay (LOS). Nonsurviving patients were significantly older (57.4 ± 23.3 vs. 42.7 ± 19.3 years old, p = 0.014) and had higher injury severity scores (ISSs) (36.4 ± 11.9 vs. 23.9 ± 10.9, p < 0.001) than were observed in surviving patients. There was no significant difference in the time to TAE between nonsurviving and surviving patients (76.9 ± 47.9 vs. 59.0 ± 29.3 min, p = 0.068). The multivariate logistic regression analysis showed that ISS and age served as independent risk factors for mortality. Every one unit increase in ISS or age resulted in a 1.154- or 1.140-fold increase in mortality, respectively (p = 0.033 and 0.005, respectively). However, the time to TAE serves as an independent factor for ICU LOS (p = 0.015). Conclusion: In pelvic fracture patients who require TAE for hemostasis, longer time to TAE may cause harm. An early hemorrhage control is suggested.
