OBJECTIVE: To analyze the factors related to the need for revision surgery due to nonunion or internal fixation failure after the treatment of distal femoral fracture with lateral locking plate (LLP). METHODS: Retrospective analysis was made of the clinical data of 130 cases with distal femoral fracture treated in our hospital from March 2005 to March 2019. SPSS 17.0 software (univariate analysis and Logistic regression analysis) was used to analyze the general condition [gender, age, body mass index (BMI), comorbidities, smoking history], injury related factors (energy of injury, open or closed injury, AO/OTA classification of fracture, fracture area distribution), operation related factors (operation time, reduction quality, postoperative infection) and construct characteristics of internal fixation. RESULTS: Twelve of 130 patients who were included in the study underwent revisional surgery, with a revision rate 9.2%. Univariate analysis showed that there were significant differences in age, BMI, AO/OTA classification, fracture area distribution, operation time, reduction quality, length of plate/fracture area, length of plate/fracture area above condylar between the two groups (P < 0.05). Logistic regression analysis showed that AO/OTA classification (A3), supracondylar involved fracture, operation time, reduction quality and the length of the plate/fracture area above the condylar were the possible related factors (P < 0.05). Destruction of the medial support ability of the femur in comminuted type A3 fracture, supra-condylar cortex area fracture involvement, increase of the bending stress of the LLP due to poor fracture reduction quality, damage of the blood supply of fracture end due to long-time operation, and stress concentration caused by insufficient length of plate might be risk factors of revisional operation after the treatment of distal femoral fracture with LLP. For the patients who needed revision after LLP treatment, additional use of medial minimally invasive plate fixation and autologous bone transplantation, change to intramedullary nail fixation were commonly used clinical treatment strategies. CONCLUSION AO/OTA classification (A3), supracondylar involved fracture, long operation time, poor reduction quality and the length of the plate/fracture area above the condylar were the possible predictive factors of the revision in distal femoral fractures treated with lateral locking plate. The appropriate application of the locking plate and operation strategy are the key to reduce the revision rate in distal femoral fractures.

PURPOSESoft tissue healing is of paramount importance in distal tibial fractures for a successful outcome. There is an increasing trend of using anterolateral plate due to an adequate soft tissue cover on ante- rolateral distal tibia. The aim of this study was to evaluate the results and complications of minimally invasive anterolateral locking plate in distal tibial fractures.

METHODSThis is a retrospective study of 42 patients with distal tibial fractures treated with minimally invasive anterolateral tibial plating. This study evaluates the bone and soft tissue healing along with emphasis on complications related to bone and soft tissue healing.

RESULTSFull weight bearing was allowed in mean time period of 4.95 months (3-12 months). A major local complication of a wound which required revision surgery was seen in one case. Minor complications were identified in 9 cases which comprised 4 cases of marginal necrosis of the surgical wound, 1 case of superficial infection, 1 case of sensory disturbance over the anterolateral foot, 1 case of muscle hernia and 2 cases of delayed union. Mean distance between the posterolateral and anterolateral incision was 5.7 cm (4.5-8 cm).

CONCLUSIONThe minimally invasive distal tibial fixation with anterolateral plating is a safe method of stabilization. Distance between anterolateral and posterolateral incision can be placed less than 7 cm apart depending on fracture pattern with proper surgical timing and technique.

OBJECTIVE: This paper is aimed at investigating the efficacy of combining internal fixation using prefabricated rib-locking titanium plate with ultrasound-guided thoracic paravertebral nerve blockade in treating multiple rib fractures among the elderly. METHODS: Retrospective analysis of 221 elderly patients with multiple rib fractures treated from February 2016 to November 2020. According to whether surgery was performed, they were divided into the plate-blockage combination group (surgical group, 102 cases) and conservative treatment group (non-surgical group, 119 cases). The surgical group consisted of 58 males and 44 females aged from 60 to 85 years old, with an average of (67.2±3.6 ) years old, who suffered from 3 to 12 rib fractures with an average of (5.3±2.1) fractures. The non-surgical group consisted of 66 males and 53 females aged from 60 to 84 years old with an average of (66.8±3.2) years old, who suffered from 2 to 11 rib fractures with an average of(6.1±2.3) fractures. The clinical data, efficacies observed, and complications associated with both groups were compared and analyzed. RESULTS: There was no significant difference in preoperative clinical data between two groups (P>0.05), and all patients were discharged smoothly. Pulmonary infection (P=0.028), atelectasis (P=0.032), respiratory failure (P=0.026), time to get out of bed (P=0.040), time to fracture healing (P=0.035), length of hospital stay in the operation group (P=0.043), visual analogue scale (VAS) at 3 days (P=0.028), 5 days(P=0.032), and 7 days(P=0.019), maximal voluntary ventilation (MVV) at 3 months after surgery (P=0.042), forced expiratory volume in one second (FEV1)(P=0.035), and maximal voluntary ventilation at 6 months, the maximal voluntary ventilation(MVV)(P=0.021) and forced FEV1(P=0.026) were all significantly better than those in non-surgical treatment group. CONCLUSION For elderly patients with severe multiple rib fractures, the proposed plate-blockade combination can timely and effectively relieve pain, restore thoracic stability, shorten hospital stay, and reduce the incidence of complications such as pulmonary infections and acute respiratory distress syndrome(ARDS) compared with non-surgical treatments. Prefabricated rib-locking titanium plates have proved to demonstrate high clinical efficacy in treating multiple rib fractures among the elderly.

PURPOSETo evaluate the clinical outcomes of locking calcaneal plate in treating calcaneal fracture (Sanders II-III) in elderly patients.

METHODSFrom October 2012 to December 2013, 23 elderly patients suffering from calcaneal fracture (Sanders II-III) were treated and followed up. There were 15 males and 8 females with the mean age of 68.5 years (range: 65-79 years). According to Sander's classification, 16 cases (16 feet) were type II fractures and 7 cases (7 feet) were type III fractures. Anteroposterior, lateral and axial views of X-ray were taken to detect the calcaneum. CT scan was done to assess the amount of comminution and articular depression. Radiological assessment was performed using Bohler's angle and Gissane's angle. Functional outcome was assessed using the Maryland foot score.

RESULTSAll the patients were followed up for 13.7 months on average (10-20 months). The mean time of bone union was 3.2 months (3-4 months). The mean time of complete weight bearing was 3.2 months (3.1-4.0 months). The soft tissue necrosis was found in 1 case. The mean Bohler's angle and Gissane's angle were 25.31° and 117.5°respectively. The overall excellent to good rate was 82.6%.

CONCLUSIONOpen reduction and internal fixation with locking calcaneal plate can obtain good functional outcome for Sanders II-III calcaneal fractures in elderly patients.

OBJECTIVETo observe clinical results for reconstruction of periprosthetic fractures of hip with cortical bone plates allografts by deep-freezing and ethylene oxide treatment.

METHODSSeven patients with periprosthetic fractures of hip underwent cortical bone plates allografts by deep-freezing at -70 degrees C after being treatment of 48 degrees C ethylene oxide. And evaluate clinical outcome by examining T lymphocytes, Harris scores, X-rays photograph, and bone scintigraphy.

RESULTSThere were not activity of immune rejection and infection in all patients. Harris scores of patients increased 21, 32, 40, 40 scores at 3, 6, 12, 24 months after surgery. T-lymphocytes, antibody and immunocomplex in blood was normal postoperation. X-ray film indicated that fracture was healed at 3 months and there was partially bone conjunction between allograft strut and host bone. There was incorporation of 85% allograft strut to host bone, and 15% allograft strut was partially absorbed at 12 months after surgery. The size of femur of host was added 3 mm to 5 mm, averaged 4.3 mm at 12 months postoperation. Density of 80% allograft plates was as same as host bone after remodeling and the absorbtion of 10% allograft plates stopped at 24 months after surgery. There was thick of nuclein in the area of allograft cortical bone plates by bone scintigraphy examination at 3 months postoperation, and the thick of nuclein was stronger at 6, and 12 months after surgery.

CONCLUSIONAllograft cortical bone plates by deep frozen at -70 degrees C after being treatment of 48 degrees C ethylene oxide is suitable for mechanical fixation and biological bone transplantation, and it can increase bone reservation, augment strength of femur once the allograft strut incorporates to host bone, and avoid removing metal implant in second operation when being applied into reconstruction femoral fracture in joint replacement.

With rapid advancement in surgical techniques and improvement in implant materials, rate of internal fixation for pubic symphyseal disruption in rotationally and vertically unstable pelvic ring injuries has increased. Among various modes of implant failure, screw/plate breakage and loosening are common complications following unstable fixation. Migration of loose screws into the urinary bladder has been reported as an extremely uncommon complication of pubic symphyseal plating. Here we present a case report of a 52-year-old female who presented with asymptomatic passage of screws in her urine following migration into the bladder, 2 years after symphyseal plating for pubic diastasis in an anteroposterior compression pelvic ring injury.
