RESUMO

BACKGROUND: Several demographic and medical factors have an established effect on mortality and function after hip fractures, however varying fracture characteristics and surgical factors have been less thoroughly investigated. The study assessed the impact of specific fracture patterns on mortality and mobility one year post hip fracture. Other surgical factors including the type of intervention, major complications and sequential fractures were assessed as well. METHODS: An institutional hip fracture registry was reviewed. Mobility status scores were calculated one year post-operatively. RESULTS: Thirty days mortality was 4.6% and one year mortality was 19.9%. There was no significant effect of fracture type on mortality. However, patients receiving hemiarthroplasty had a significantly higher mortality (28.1%) than other patients receiving internal fixation (18.6%) or total hip arthroplasty (4%). An increased mobility status after intra-capsular fractures over extracapsular fractures was demonstrated. Patients receiving total hip arthroplasty had significantly better mobility at one year than patients with fracture fixation or hemiarthroplasty. Major complications and sequential fractures had no significant effect on outcome. CONCLUSIONS: Critical factors that influence decision making for orthopedic surgeons are revealed to have a lesser effect on the patient's ultimate outcome.

RESUMO

Periprosthetic femoral fractures around the femoral stem of a hip prosthesis constitute a serious challenge. The number of these fractures, associated with a high failure rate and a high number of overall complications, including higher mortality, has been on an increase worldwide. Stable femoral stems are indicated for osteosynthesis, while in case of loosening the method of choice is the replacement by a revision implant. The aim of osteosynthesis of periprosthetic femoral fractures is a stable fixation with soft tissue preservation which results in faster union allowing the patient to return to pre-injury activities. Biomechanical studies on cadavers or on synthetic models and computer simulations make it possible to evaluate the fixation strength in various types of implants in dependence on fracture characteristics and bone quality, but cannot be substituted for clinical trials since there is no direct proportion between fixation rigidity and fracture union. Fundamental principles that shall be followed in osteosynthesis of periprosthetic fractures can be deduced from the available studies. Proximal fixation by screws or a combination of screws and cables are biomechanically more advantageous than the Ogden fixation by cerclage wires or cables. Bicortical fixation enabled by state-of-the-art implants of LAP-LCP or NCB type represents a significantly more stable construction compared to monocortical fixation and led to reduced use of structural allografts. Better stability can be achieved by "double plating" technique which is applied especially in revision surgeries, but also in osteoporotic periprosthetic fractures with a defect zone. In these cases, osteosynthesis with long plates is recommended, bridging the entire femur, i.e. distally with femoral condyles fixation since this prevents the risk of a fracture below the plate. In shorter plates, this risk created by stress concentration at the end screw is amplified when a distal bicortical locking screw is used. That is why it is beneficial to reduce this stress by a monocortical screw or with the use of a conventional screw. Adherence to the principles regarding the position, type and number of screws constitutes the key parameter of successful osteosynthesis of periprosthetic fractures. Key words: hip joint, arthroplasty, periprosthetic fractures, biomechanics of osteosynthesis.

RESUMO

Objective: To evaluate the best entry region and trajectory of anterior transpedicular root screws (ATPRS). Methods: From January 2018 to May 2019, 50 cervical CT date integral of healthy people were selected from Ningbo No. 6 Hospital and were confirmed no obvious defect. Of these, 24 cases were males and 26 were females, aged 20-49 (32±5) years. The CT data was imported into Mimics by DICOM format, then 3D reconstruction was performed. In the coronal plane, the area from the centreline of the anterior of C(3-7) to the left Z-line(marked a line through the intersection of the anterior of the luschak joint and upper endplates, parallel to the centralline of the anterior of the vertebral body) was divided into nine areas. Then virtual screw with diameter of 3.5 mm was inserted. Record the length of screw of each area (L), the angle between screw and the posterior of the vertebral body in horizontal plane(α), the angle between screw and the anterior of the vertebral body in sagittal plane (ß), individually. The data between groups were compared by independent sample t test. Results: The best regions were zone 9 of C(3), C(4); zone 8, 9 of C(5); zone 2-3, 5-9 of C(6); zone 1-9 of C(7) in men. And these were zone 9 of C(3); zone 3, 6, 8 and 9 of C(4), C(5); zone 2-3, 5-9 of C(6); zone 1-9 of C(7) in women. The distribution of best region was almost the same in men and women, zone 9 of each segment was the best region, and the screw length was the longest. It increased gradually from C(3) to C(7). C(3) had the least region, C(4) and C(5) had less, while C(6) and C(7) had the most. The horizontal angle of C(3-7) in men and women were 44.0°-47.2°, 40.2°-45.3° in zone 1, 4 and 7, respectively; 35.1°-41.4°, 34.6°-38.7° in zone 2, 5 and 8, respectively; 30.0°-37.2°, 30.2°-34.5° in zone 3, 6 and 9, respectively; and it demonstrated a gradually decreased trend. The sagittal angle of C(3-7) in men and women was 85.3°-97.4°, 80.5°-88.9° in zone 1-3, respectively; 101.2°-113.7°, 101.0°-109.3° in zone 4-6, respectively; 116.6°-128.8°, 119.9°-125.3° in zone 7-9, respectively; and it demonstrated a gradually increased trend. There was no significant difference in the horizontal and sagittal angle between men and women (both P>0.05). Conclusions: Anterior transpedicular root screw is a feasible internal fixation technique. It has wide region and the Z-line can be used as a reference for screw placement.

RESUMO

Objective: To compare the effect of intramedullary nail and locking plate in the treatment of proximal humeral fractures in the elderly. Methods: A total of 37 elderly patients with proximal humeral fractures were selected from April 2016 to June 2018 in Tianjin Hospital, including 13 males and 24 females, aged (66±5) years. The patients were divided into observation group (17 cases) and control group (20 cases) according to the random number table, and were treated with multiloc intramedullary nail and locking plate respectively. The operation time, blood loss, healing time of fractures, visual analogue scale of pain, Neer shoulder function score were recored and compared between the two groups. The data were compared with t test between the two groups. Results: The operation time of the observation group was shorter than that of the control group ((72±7) min vs (89±9) min, t=6.365, P<0.05); the intraoperative bleeding volume was lower than that of the control group ((56±6) ml vs (74±8) ml, t=7.923, P<0.05). The superior rate of shoulder function was 94.1%(16/17) in the observation group and 90.0%(18/20) in the control group (χ(2)=0.209, P>0.05). The VAS score of the observation group was lower than that of the control group on the first day after operation (t=4.706, P<0.05); the Neer shoulder function score of the observation group was higher than that of the control group on the sixth month after operation (81±8 vs 76±8, t=2.156, P<0.05). Six months after the operation, the valgus angle (19.21°±2.88°) of the observation group was larger than that of the control group (16.32°±2.63°, t=3.189, P<0.05), the humeral head varus angle (3.57°±0.47°), the humeral neck stem angle (139°±10°) was smaller than that of the others (5.24°±1.26°), (146°±13°) (t=5.159, 2.258, both P<0.05). There was no significant difference in shoulder function score and complication rate 12 months after operation between the two groups (both P>0.05). Conclusion: Both intramedullary nailing and locking plate can achieve better results in the treatment of proximal humeral fractures in the elderly, but the operation time of intramedullary nailing is shorter, the pain after operation is lighter and the recovery is faster.

RESUMO

Objective: To investigate the effectiveness of percutaneous compression plate (PCCP) fixation for femoral neck fracture. Methods: A clinical data of 100 patients with femoral neck fractures who were treated with internal fixation were analyzed retrospectively. The fractures were fixed with the cannulated screws (CS) in 55 patients (CS group) and with the PCCP in 45 patients (PCCP group). There was no significant difference in gender, age, the cause of injury, the fracture type, complications, and disease duration between the two groups ( P>0.05). The quality of fracture reduction, bone resorption, screw slipping, femoral neck shortening, complications (nonunion, failure of fixation, and osteonecrosis of femoral head), and functional recovery of hip (Harris score) were compared between the two groups. Results: All incisions healed by first intention. All patients were followed up 24-56 months, with an average of 30.7 months. The quality of fracture reduction was excellent in 26 cases, good in 18 cases, fair in 9 cases, and poor in 2 cases in CS group and excellent in 21 cases, good in 17 cases, fair in 4 cases, and poor in 3 cases in PCCP group, showing no significant difference between the two groups ( Z=-0.283, P=0.773). The incidence of nonunion in PCCP group was significantly lower than that in CS group ( P=0.046), and the fracture healing time in PCCP group was shorter than that in CS group ( t=2.155, P=0.034). There was no significant difference in the incidences of bone resorption, screw slipping, femoral neck shortening, failure of fixation, and osteonecrosis of femoral head between the two groups ( P>0.05). The overall complication rates were 27.27% (15/55) in CS group and 8.89% (4/45) in PCCP group, showing significant difference ( χ 2=5.435, P=0.020). The Harris score in PCCP group at 6 months after operation was significantly higher than that in CS group ( t=-2.073, P=0.041). However, there was no significant difference in the Harris score at 12, 18, and 24 months after operation between the two groups ( P>0.05). Conclusion: Stable sliding compression of PCCP is benefit for the femoral neck fracture healing, especially shortening union.

RESUMO

Objective: To observe the short-term effectiveness of Endobutton plate in the reconstruction of Lisfranc ligament in tarsometatarsal joint injury. Methods: Between March 2015 and July 2018, 18 patients with tarsometatarsal joint injuries were treated with Lisfranc ligament reconstruction by Endobutton plate. There were 12 males and 6 females with an average age of 32.5 years (range, 16-55 years). The causes of injury were traffic accident in 8 cases, falling from height in 3 cases, crushing by a heavy objective in 4 cases, and spraining in 3 cases. There were 10 cases of Myerson type A, 4 of type B1, 2 of type B2, 1 of type C1, and 1 of type C2. The interval between injury and operation ranged from 3 to 9 days (mean, 4.9 days). X-ray examination was performed regularly after operation to measure the distance between the first and the second metatarsal joints, and the visual analogue scale (VAS) score was used to evaluate the pain relief. At last follow-up, the reduction of tarsometatarsal joint was evaluated by measuring and comparing the height of the affected and healthy arches. The foot function was evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: The average follow-up time was 15.8 months (range, 10-28 months). All incisions healed by first intention. X-ray reexamination showed that there was no screw loosening or plate fracture. There were significant differences in the distance between the first and the second metatarsal joints and VAS score at 3 months after operation, before removal of the internal fixator, and at last follow-up when compared with preoperative values ( P<0.05). There was no significant difference between the time points after operation ( P>0.05). At last follow-up, there was no significant difference in the arch height between affected foot [(5.3±0.2) mm] and healthy foot [(5.4± 0.3) mm] ( t=1.798, P=0.810). The AOFAS score of foot function was 89.5±7.3 with excellent in 12 cases, good in 4 cases, and fair in 2 cases. The excellent and good rate was 88.9%. Conclusion: The reconstruction of Lisfranc ligament with Endobutton plate can stabilize the tarsometatarsal joint and achieve satisfactory foot function at early stage.

RESUMO

Objective: To explore the necessity of repairing the deep layer of deltoid ligament in the treatment of mixed medial injury associated with ankle fractures. Methods: Between January 2016 and December 2018, 12 patients with mixed medial injury associated with ankle fractures were treated with the fixation of the lateral malleolus by bone plates, the fixation of the anterior colliculus of medial malleolus by cannulated screws, and the repair of the deltoid ligament by suture anchors. There were 8 males and 4 females, with an average age of 42 years (range, 18-56 years). According to the Lauge-Hansen classification criteria, there were 11 cases of supination-external rotation type and 1 case of pronation-external rotation type. According to the Weber classification criteria, all cases were type B. The time from injury to operation was 3-6 days, with an average of 4.7 days. In each patient, X-ray films of anteroposterior and lateral views and mortise view of ankle were taken postoperatively. The motion range of ankle joints was observed. The function of the ankle and the outcome of the treatment were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system, Olerud-Molander scoring system, and the visual analogue scale (VAS) score. Results: All cases were followed up 12-42 months (mean, 28 months). The 12 patients returned to their pre-injury jobs. Five patients with sports injury completely recovered to their pre-injury motor function. No patient experienced persistent medial ankle pain or ankle instability. At last follow-up, the ankle range of motion in dorsiflexion was 9°-25° (mean, 17.96°), which was 0°-11° (mean, 4.02°) less than that in normal side; the range of motion in plantar flexion was 38°-50° (mean, 43.90°), which was 0°-7° (mean, 2.53°) less than that in normal side. The AOFAS score was 88-100 (mean, 96.7); the Olerud-Molander score was 90-100 (mean, 96.5); the VAS score was 0-3 (mean, 1.1). Conclusion: It is necessary to repair the deep layer of deltoid ligament in the mixed medial injuries associated with ankle fracture, which include anterior colliculus fracture and deep deltoid ligament injury. A better outcome can be achieved by employing the suture anchor repair method.

RESUMO

Objective: To summarize the research progress of medial buttress plate assisted fixation for femoral neck fractures in young adults. Methods: The literature about buttress plate assisted fixation for femoral neck fractures in young adults was widely reviewed and analyzed. The design principle, background, biomechanical characteristics, and clinical results of buttress plate were summarized. Results: Medial buttress plate assisted fixation is the latest treatment of femoral neck fractures in young adults, which can convert the shear force at the fracture sides into compression force and promote fracture healing. Medial buttress plate can improve the biomechanical stability of femoral neck fractures and reduce the maximum stress of fixation implants. In clinical, the medial buttress plate can maintain fracture reduction, reduce the incidences of nonunion and surgical failure, and improve hip joint function. Conclusion: Medial buttress plate assisted fixation can achieve good effectiveness for femoral neck fractures in young adults. However, due to the preliminary application, its indications, fixation implants, and long-term effectiveness need to be further studied and improved.

RESUMO

BACKGROUND: At present, the treatment of base fractures of the fifth metatarsal, especially the area I fractures, is still a controversial topic. The objective of our work was to assess the radiological and clinical outcomes of displaced avulsion fractures of the fifth metatarsal base after treated with conservative treatment or intramedullary screw. METHODS: All of the fifth metatarsal fractures patients underwent surgery by the senior authors in our hospital from January 2017 to December 2019 were reviewed. Institutional Review Board in the Subsidiary Hospital of Guizhou Medical University approved this study. Patients with the following conditions can be included:Patients with the following conditions will be excluded: follow-up less than 6 months; open fracture; pathological fracture; osteoporotic fracture; patients have the history of ankle or foot surgery. Radiographs were taken at 1, 3, 6 and 12 months in outpatient follow-up. The following outcomes were assessed in the follow-up: functional outcomes, the score of patient satisfaction, as well as the motion range, and complications. All the statistical analyses were implemented via applying the software of SPSS Version 12 (SPSS Inc, Chicago, IL). RESULTS: We hypothesized that there was no remarkable difference between two groups in the outcomes after operation. TRIAL REGISTRATION: This study protocol was registered in Research Registry (researchregistry6024).

RESUMO

The purpose is to evaluate hip fractures due to gunshot wounds (GSW) to the hip, which are treated surgically, and the complications. Patients who sustained a low velocity GSW with fracture to the femoral head/neck and intertrochanteric/peritrochantric region at three Level 1 Trauma Centers were eligible. There were 69 patients (63 males-91%), with an average age of 29 (18-60). Nine patients had orthopaedic surgical site infections. There were 6 nonunions, 4 patients with hardware failure, 2 cases of avascular necrosis (AVN), 3 patients with post traumatic arthritis (PTA) and 20 patients with heterotopic ossification (HO). There was no significant difference found regarding fracture site or type of fixation with regards to complications. This represents the largest study of surgically treated GSW to the hip. Of patients studied, 61% sustained additional GSW. These injuries are not benign; the main complications being infection and heterotopic ossification.

RESUMO

This study analyzes the outcomes of patients treated for high energy midfoot injuries with temporary stabilization (TS) prior to definitive operative fixation compared to a control group (C) treated initially with splint only. Three Level 1 trauma centers reduced and temporized high energy Lisfranc injuries. A matched control group was compared with the intervention group. Clinical parameters, complications and need for additional surgery were evaluated. There were 15 patients in group C and 29 patients with temporary stabilization (TS). Both the TS and C groups demonstrated no significant difference in the number of additional operations, infection rate, incidence of deep vein thrombosis (DVT), nonunion and need for orthotics postoperatively (p > 0.05). Staged treatment of high energy Lisfranc injuries in the TS group led to a delay in definitive fixation or arthrodesis while having a similar minimal complication rate relative to the controls. This is a Level III, Retrospective Case Control Study. (Journal of Surgical Orthopaedic Advances 29(3):154-158, 2020).

RESUMO

Retrospectively compare outcomes of prophylactic fixation to nonoperative treatment of incomplete or non-displaced femoral neck stress fractures (FNSF) in young adults. Outcomes of 82 patients (mean age 21.7 years) who were diagnosed with incomplete or non-displaced FNSFs from 2002 to 2015 were compared. Forty-one underwent prophylactic fixation; the remaining were treated without surgery. Fracture characteristics and complications were recorded. Pain scores, modified Harris Hip Scores (mHHS), and Hip Outcome Scores (HOS) were obtained and compared. The average fracture line in the operative group was 67% of the femoral neck width versus 18% in the nonoperative group (p < 0.001). There was no difference in outcome scores between the two groups. Prophylactic fixation of high-risk non-displaced FNSFs resulted in similar outcome scores to non-operative management of lower-risk variants at an average of 7.3 years follow up. No patient in either group progressed to a displaced femoral neck stress fracture. (Journal of Surgical Orthopaedic Advances 29(3):173-176, 2020).

RESUMO

RATIONALE: The objective of the present study was to evaluate the accuracy, effectiveness, and safety of screw view model of navigation (SVMN) guided minimal invasive percutaneous pelvic screws (PPSs) insertion for lateral compression pelvic ring injuries (PRI). PATIENT CONCERNS: A female patient experienced a high falling injury, and presented with pain, swelling, deformity, and movement limitation of the left hip for 3 hours. DIAGNOSES: She was diagnosed with pelvic fractures, left iliac fracture, left pubic branch fracture, left ischial branch fracture, and lumbar transverse process fracture. INTERVENTIONS: We used a SVMN technique to guide PPSs insertion, including a percutaneous anterior inferior iliac spine screw, a percutaneous iliac screw (PIS), and a percutaneous sacroiliac screw (PSIS). OUTCOMES: In total, 3 PPSs were inserted and all were presented with excellent position postoperatively. The designing time of all screws was 11.7 minutes, the time of all guide needles insertion was 18.1 minutes, the time of all screws insertion was 32.8 minutes, blood loss was 21 mL, and the time of radiation exposure lasted 7.2 minutes. Moreover, surgical complications, including neurovascular compromise, wound infection, fracture nonunion, and screw loosening, were not observed during the 12 months follow up visit. LESSONS: SVMN technique guided PPSs insertion is an effective and safety approach for the treatment of PRI in selected patients. Besides, it is necessary for surgeons to master the rationale of computer navigation, to familiar with the anatomy of pelvis and to select suitable patients.

RESUMO

Objective: To explore the effectiveness of simple Ilizarov ring external fixation technique in treatment of tibial plateau fractures complicated with osteofascial compartment syndrome. Methods: Between September 2013 and March 2017, 30 patients with tibial plateau fractures complicated with osteofascial compartment syndrome were treated with simple Ilizarov ring external fixation technique. There were 23 males and 7 females, with an average age of 34.4 years (range, 23-43 years). The injuries were caused by traffic accident in 12 cases, by falling from height in 4 cases, by falling in 8 cases, and by a crashing object in 6 cases. The time from injury to admission was 1-12 hours (mean, 4.8 hours). According to the Schatzker classification, there was 1 case of type Ⅱ, 3 cases of type Ⅲ, 10 cases of type Ⅳ, 7 cases of type Ⅴ, and 9 cases of type Ⅵ. All patients underwent fasciotomy due to osteofascial compartment syndrome; the interval between fasciotomy and operation was 10-15 days (mean, 12.5 days). Knee Society Score (KSS) and Ilizarov Method Research and Application Association (ASAMI) protocol were used to evaluate knee function. Results: The operation time was 110-155 minutes (mean, 123.1 minutes); the intraoperative blood loss was 100-500 mL (mean, 245 mL); the postoperative hospital stay was 3-5 days (mean, 3.8 days). All patients were followed up 20-24 weeks (mean, 22.7 weeks). Except for 2 patients with signs of needle tract infection, no other complication occurred. X-ray films showed that the fractures healed, and the healing time was 10-20 weeks (mean, 14.6 weeks). At last follow-up, the KSS clinical score was 70- 95 with an average of 87.5; the functional score was 70-90 with an average of 79.0. According to ASAMI protocol evaluation, the effectiveness was rated as excellent in 24 cases, good in 3 cases, fair in 2 cases, and poor in 1 case. Conclusion: For tibial plateau fractures complicated with osteofascial compartment syndrome, simple Ilizarov ring external fixation technique can basically restore joint function and has fewer complications. It is a relatively safe and effective treatment method.

RESUMO

Objective: To explore the effectiveness of the calcaneal plate bridge reconstruction plate for acetabular fracture involving quadrilateral surface via modified Stoppa approach. Methods: Between January 2015 and December 2017, 18 patients with acetabular fracture involving quadrilateral surface were treated with the calcaneal plate bridge reconstruction plate via the modified Stoppa approach. There were 12 males and 6 females. The age ranged from 28 to 63 years (mean, 39 years). The cause of injury was traffic accident in 13 cases and falling from height in 5 cases. According to the Letournel-Judet classification, there were 10 cases of anterior and posterior column fractures, 6 cases of T-shaped fractures, and 2 cases of anterior column and posterior semi-transevere fractures. The interval from injury to operation was 6 to 24 days (mean, 8.6 days). The reduction quality was assessed by postoperative X-ray film and CT according to the criteria proposed by Matta. The hip joint function was assessed by the modified Merled'Aubigné-Postel score. Results: The operation time was 120-240 minutes (mean, 165 minutes) and the intraoperative blood loss was 600-1 400 mL (mean, 850 mL). All patients were followed up 18-30 months (mean, 24.5 months). There were 2 cases of the fat liquefaction of abdominal incisions, 3 cases of intraoperative injury of lateral femoral cutaneous nerve, 1 case of lower limb thrombosis, and 1 case of abdominal pain and hematuria due to intraoperative accidental bladder injury. According to the criteria proposed by Matta, the reduction quality rated as anatomic reduction in 12 cases, satisfactory reduction in 5 cases, and unsatisfied reduction in 1 case, and the satisfaction rate was 94.4%. All fractures healed with the healing time of 3-5 months (mean, 3.4 months). During follow-up, no internal fixator loosening, breakage, or fracture displacement occurred. At last follow-up, according to modified Merled'Aubigné-Postel score, hip joint functions rated as excellent in 11 cases, good in 4 cases, fair in 2 cases, and poor in 1 case. The excellent and good rate was 83.3%. Conclusion: Application of calcaneal plate bridge reconstruction plate via the modified Stoppa approach for the acetabular fracture involving the quadrilateral surface can obtain satisfactory effectiveness.

RESUMO

Objective: To investigate the effectiveness of two surgical approaches in the treatment of type Ⅳ Pipkin fracture. Methods: The clinical data of 15 patients with type Ⅳ Pipkin fracture treated surgically between July 2013 and June 2018 were retrospectively analyzed. According to different surgical approaches, they were divided into group A (8 cases, using K-L posterior approach) and group B (7 cases, using greater trochanter osteotomy approach). There was no significant difference in gender, age, cause of injury, and interval from injury to operation between the two groups ( P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, fracture healing time, and complications of the two groups were recorded. Hip joint function recovery was evaluated according to Thompson-Epstein functional evaluation system. Results: All the 15 patients were followed up 1-5 years, with an average of 2.5 years. There was no significant difference in operation time between the two groups ( t=14.681, P=0.100); the incision length, intraoperative blood loss, and fracture healing time in group A were all greater than those in group B, and the hospital stay was shorter than that in group B, showing significant differences ( P<0.05). In group A, 1 patient presented hip pain, clasthenia, and limited mobility after operation, 1 patient presented ossifying myositis, 1 patient presented osteonecrosis of the femoral head, 1 patient presented fat liquefaction of incision, and 1 patient presented sciatica, with a complication incidence of 62.5%. Postoperative hip pain occurred in 1 patient and ossifying myositis in 2 patients in group B, with a complication incidence of 42.9%. There was no significant difference in the incidence of complications between the two groups ( χ 2=-0.735, P=0.462). At last follow-up, according to Thompson-Epstein functional evaluation system, the results in group A were excellent in 3 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 62.5%; in group B, the results were excellent in 4 cases, good in 2 cases, and fair in 1 case, and the excellent and good rate was 85.7%. There was no significant difference in good and fair rate between the two groups ( χ 2=-0.990, P=0.322). Conclusion: K-L posterior approach is more convenient in the fracture treatment during operation, but it has greater trauma, greater vascular damage, and more blood loss. The greater trochanter osteotomy approach can better protect the blood supply of femoral head, shorten the operation time, reduce intraoperative blood loss, and reduce postoperative complications. It is an ideal way in the surgical treatment of type Ⅳ Pipkin fracture.

RESUMO

Objective: To review the research progress of wrist arthroscopy assisted treatment of distal radius fractures. Methods: To summarize and describe the anatomical characteristics and fracture classification of the distal radius, indications and contraindications of wrist arthroscopy-assisted treatment, surgical methods, and associated soft tissue injuries, and summarize the advantages and disadvantages of the operation through a large number of literature at home and abroad on the treatment of distal radius fractures assisted by wrist arthroscopy. Results: Wrist arthroscopy as a minimally invasive technique for the treatment of distal radius fractures, compared with traditional surgery, can accurately observe intra-articular damage and perform operations under the microscope to avoid secondary damage to blood vessels, nerve, and tendon, etc., and can achieve one-stage repair and reconstruction by repairing the ligament, trigonal fibrocartilage complex, and carpal dislocation. It has the advantages of less trauma, fast postoperative recovery, extensive indications, fewer complications, and satisfactory effectiveness. Conclusion: Wrist arthroscopy has advantages that traditional X-ray film, CT, MRI, and arthrography examinations do not have. Moreover, wrist arthroscopy has achieved satisfactory effectiveness in the adjuvant treatment of intra-articular distal radius fractures.

RESUMO

Objective: To review the research progress in the diagnosis and treatment of distal tibiofibular syndesmosis injury. Methods: The recent literature about distal tibiofibular syndesmosis injury was reviewed and analyzed. Results: Distal tibiofibular syndesmosis injury is commonly seen in ankle joint injury, the anatomical complexities make diagnosis and treatment difficult. Preoperative physical examination, radiologic evaluation, and intraoperative stress-testing are important for the diagnosis. Aggressive treatment is also recommended for these injuries to prevent long-term chronic instability. Internal fixation is the main treatment, including metal screw, degradable screw, elastic fixation, and hybrid techniques. Metal screw fixation is still the current mainstream, but elastic fixation represented by Suture-button is more in line with the physiological characteristics of ankle joint, and the rate of secondary operation is low while the clinical outcome is satisfactory. The application prospect of elastic fixation is worthy of expectation. Conclusion: It's crucial for patient with ankle fracture to repair the distal tibiofibular syndesmosis injury. How to diagnose the injury more accurately and simply, how to increase the success rate of reduction, and how to reduce the complications of surgery are still worthy for further exploration.

RESUMO

The talus is unique in having a tenuous vascular supply and 57% of its surface covered by articular cartilage. Fractures of the head, neck, or body regions have the potential to compromise nearby joints and impair vascular inflow, necessitating surgical treatment with stable internal fixation in many cases. The widely preferred approach for many talar neck and body fractures is a dual anterior incision technique to achieve an anatomic reduction, with the addition of a medial malleolar osteotomy as needed to visualize the posterior talar body. Percutaneous screw fixation has also demonstrated success in certain patterns. Despite this modern technique, osteonecrosis and osteoarthritis remain common complications. A variety of new treatments for these complications have been proposed, including vascularized autograft, talar replacement, total ankle arthroplasty, and improved salvage techniques, permitting some patients to return to a higher level of function than was previously possible. Despite these advances, functional outcomes remain poor in a subset of severely injured patients, making further research imperative.

RESUMO

Fractures of the surgical neck of the scapula combined with a fracture of the coracoid base constitute a specific and rare type of a fracture pattern. When displaced, they present a severe, completely unstable type of surgical neck fracture, requiring a precise CT diagnosis, open reduction and stable internal fixation of the fracture via the Judet approach. The aim of this study is to describe our four cases and discuss three others reported to date.
