OBJECTIVE: To explore the clinical efficacy of external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury. METHODS: From January 2018 to December 2019, 13 patients received micro-locking plate combined with closed reduction treatment due to the fifth metatarsal comminuted fracture with severe soft tissue injury. There were 11 males and 2 females patients, ranging in age from 21 to 69 years. According to the fracture AO fracture classification, 9 cases belonged to type 87(S)-C2.2 and 4 cases belonged to type 87(S)-C2.1. The fifth metatarsal cuneiform articular surface was not involved, and all of them were comminuted fractures of the fifth metatarsal shaft. All soft tissues were damaged to varying degrees. Three patients got small defect of skin and soft tissue, and they were treated with debridement and suture after one-stage emergency surgery. The fracture healing and complications were observed, and the clinical efficacy was evaluated according to the midfoot function score of American Orthopaedic Foot & Ankle Society (AOFAS) at the latest follow-up. RESULTS: All patients were followed up, and the duration ranged from 3 to 12 months. One patient had delayed union. One patient had local skin necrosis and was treated with second-stage skin grafting to repair the wound surface. No external screw breakage or infection was reported, the skin soft tissue healed satisfactorily and reached bony union, with the union time ranging from 8 to 19 weeks. The postoperative functional recovery was rated according to the midfoot score of AOFAS, the score ranged from 49 to 98, and 7 patients got an excellent result, 4 good, 1 fair and 1 poor. CONCLUSION: The external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury has the advantages of simple operation, good stability and low infection rate, which is helpful to the repair of soft issue injury, and the fixation can be removed early in outpatient clinic. To sum up, this surgical procedure is suitable for patients with severe soft tissue injury and comminuted fracture to avoid periosteum stripping. The space occupying is smaller than the micro-external fixator, which is convenient for patients with early functional exercise.

OBJECTIVE: To investigate the related factors of aseptic necrosis of femoral head after closed reduction and internal fixation of femoral neck fracture. METHODS: From January 2009 to January 2016, 236 patients with femoral neck fracture were treated with closed reduction and internal fixation with 3 hollow lag screws, including 111 males and 125 females, aged from 19 to 89 (50.17±12.88) years. According to the follow-up results, the correlation of aseptic necrosis of femoral head was analyzed. Univariate analysis of age, gender, injured side, body weight, injury mechanism, preoperative waiting time, Garden classification and whether there was comminution of femoral neck cortex was conducted to obtain the independent variables with significant difference. Then binary logistic regression analysis was conducted to explore the independent risk factors of avascular necrosis of femoral head. RESULTS: The average follow-up period of 236 cases was 4.58 years. There were significant differences in the range of injury (24.69% vs. 5.16%, χ2=19.405, P=0.000), operation waiting time>48 hours (20.00% vs. 6.38%, χ2=10.065, P=0.002), Garden type â ¢/â £ (18.52% vs. 2.97%, χ2=13.357, P=0.000), femoral neck cortex comminution (66.67% vs. 4.88%, χ2=39.968, P=0.000). Multivariate logistic regression analysis showed that:injury mechanism [high energy injury, Exp (B)=4.397, 95%CI=(1.672-11.562), P=0.003], preoperative waiting time >48 h [Exp (B)= 3.060, 95%CI=(1.176-7.966), P=0.022], comminution of femoral neck cortex [comminution of femoral neck pressure side cortex, Exp (B)=3.944, 95%CI=(1.245-12.494), P=0.020;comminution of femoral neck pressure side and tension side cortex, Exp(B)= 23.761, 95%CI=(3.805-148.374), P=0.001) were independent risk factors for avascular necrosis after internal fixation of femoral neck fracture. Garden type â ¢/â £ was not an independent risk factor in this study [Exp (B) = 1.985, 95%CI=(0.436-9.032), P=0.375]. CONCLUSION: High energy injury, preoperative waiting time (>48 h) and comminution of femoral neck cortex were independent risk factors for aseptic necrosis of femoral head. In addition, cortical comminution on the pressure side and tension side of the femoral neck is a strong prognostic risk factor for aseptic necrosis of the femoral head, because it indicates a more serious and complex injury mechanism.

OBJECTIVE: To explore the clinical effect of bridging system in the treatment of severe comminuted femoral fracture. METHODS: From March 2016 to October 2018, 50 patients with severe comminuted femoral fracture including 35 males and 15 females, aged 48 to 72(54.6±8.7) years, were admitted. All cases were comminuted fractures of the femoral shaft, 16 with proximal femur fractures and 7 with distal femur fractures. All cases were all unilateral fractures, 23 on the left and 27 on the right. The time from injury to operation was 5 to 60 (26.7±13.3) hours. The cause of injury was traffic accident, 12 cases with high fall, 35 cases fell and 3 cases fell accidentally. The patients were treated with bridge combined internal fixation system, and the operative effect and fracture healing were analyzed. RESULTS: The operation was successful in all patients. There was no change to other fixed operation. The operation time was (75.8±12.3) min, the amount of bleeding was(356.4±64.8) ml, and there was no serious postoperative complications such as infection, internal fixation displacement, re fracture and nonunion. After 6 to 36 months follow-up, the fracture healing was evaluated by Warden's score. With the extension of observation time, Warden's score gradually increased, and the time of bone healing was(5.5±0.9) months. Harris score and HSS score were used to evaluate the function of hip and knee joint respectively. With the extension of time, Harris score and HSS score increased gradually. Six months after operation, Harris score was 83.5±11.2, HSS score was 79.7±10.5. During the follow-up period, there were no serious complications such as internal fixation displacement, re-fracture, nonunion of fracture and deep vein thrombosis of lower extremity. CONCLUSION: The bridge combined internalfixation system has better safety and effectiveness in the treatment of severe comminuted femoral fracture. As long as the requirements of local anatomy and biomechanics are strictly mastered and the operation risks are fully evaluated in combination with imaging, the better fixation effect can be achieved. The operation has less trauma, fewer complications and simple operation, which is believed to have a wider application potential. Due to the limited sample size and follow-up time, no clinical control was set up, the results of the study still need to be further verified by prospective trials.

OBJECTIVE: Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. METHODS: Nineteen consecutive patients who underwent single-stage reconstruction with titanium mesh for FCCD of the skull from April 2014 to June 2018 were retrospectively analyzed. The demographic and radiological characteristics of the patients with FCCD were investigated. The characteristics associated with surgery and outcome were also evaluated. RESULTS: The frequency of TBI in men (94.7%) was significantly higher than that in women. Most FCCDs (73.7%) occurred during work, the rest were caused by traffic accidents. The mean interval between TBI and surgery was 7.0±3.9 hours. The median Glasgow coma scale score was 15 (range, 8-15) at admission and 15 (range, 10-15) at discharge. FCCD was frequently located in the frontal (57.9%) and parietal (31.6%) bones than in other regions. Of the patients with FCCDs in the frontal bone, 62.5% had paranasal sinus injury. There were five patients with fractures of orbital bone, and they were easily reconstructed using titanium mesh. These patients were cosmetically satisfied. Postoperatively, antibiotics were used for an average of 12.6 days. The mean hospital stay was 17.6±7.5 days (range, 8-33). There was no postoperative seizure or complications, such as infection. CONCLUSION: Immediate bony fragments replacement and reconstruction with reconstruction titanium mesh for FCCD did not increase infectious sequelae, even though FCCD involved sinus. This suggests that immediate single-stage reconstruction with titanium mesh for FCCD is a suitable surgical option with potential benefits in terms of cost-effectiveness, safety, and cosmetic and psychological outcomes.
RESUMO
BACKGROUND: The open reduction of craniofacial bone fractures requires internal fixation using metal plates and screws, which have been considered the gold standard. However, metal implants pose a risk of palpation, protrusion, and foreign body reaction, and they may require an additional operation for removal. Recently, good results have been reported for absorbable implants which complement the disadvantages of metal implants. This study presents the results of using absorbable mesh, plates, and screws with cyanoacrylate for more accurate and firmer fixation of comminuted fractures of the maxilla. METHODS: In total, 235 patients underwent operations for comminuted fractures of the maxilla. From January 2012 to December 2014, absorbable mesh and screws were used in 114 patients, while from January 2015 to December 2017, absorbable mesh, plates, and screws with cyanoacrylate were used in 121 patients. Open reduction of the bone fragments was performed, after which absorbable implants were accurately molded and fixed by screws. RESULTS: All patients underwent postoperative computed tomography scans, which showed highly accurate reduction and firm fixation in the patients who underwent procedures using absorbable implants, screws, and cyanoacrylate. There were no postoperative complications or cases of abnormal facial contour. CONCLUSION: When absorbable implants and screws are used for maxillary fractures, no additional surgery to remove the metal plate is required. In addition, the use of cyanoacrylate enables accurate and firm fixation of the tiny bone fragments that cannot be fixed with screws.
RESUMO
OBJECTIVE: To explore clinical efficacy of limited external fixation with plastic paperboard in treating senile proximal comminuted humeral fracture. METHODS: From June 2015 to December 2017, 32 senile patients with proximal comminuted fracture of humerus were treated with plasticized cardboard after manual external fixation. Among them, including 13 males and 19 females aged from 55 to 85 years old with an average of(68.22±8.36) years old; 18 patients on the left side and 14 patients on the right side; all patients were regularly review shoulder X-rays and performed appropriate functional exercises. Constant-Murley shoulder joint scoring was used to evaluate clinical effects. RESULTS: Thirty-two patients were followed up for 3 to 12 months with an average of (4.97±2.39) months. All patients were underwent functional exercise under guidance of physicians. Nine patients were treated with topical Chinese herbal moist heat compresses to promote shoulder function recovery. Thirty-one patients were obtained fracture healing, the time ranged from 5 to 12 weeks with an average of(7.44±1.72)weeks. One patient was not healed due to comminuted fracture of fracture end and the separation was large, the blood supply to humeral head was insufficient for necrosis absorption. Postoperative Constant-Murley shoulder score at 3 months was 87.56±6.93; 15 patients got excellent results, 14 good, 2 fair and 1 poor. CONCLUSIONS: Limited external fixation with plastic paperboard for the treatment of senile proximal comminuted humeral fracture could ensure biomechanical stability of fracture, promote early recovery of shoulder joint function and shorten recovery time.

OBJECTIVE: To explore the feasibility of using computer-aided design(CAD) combined with 3D printing technology to repair and reconstruct the comminuted fracture of the posterior wall of acetabulum with osteochondral defect, to evaluate the biomechanical properties of composite titanium nitride bioceramic coatings with porous titanium alloy scaffolds and steel plate integrated implants. METHODS: Based on CT images of continuous tomography, the computer-aided design software was used to construct a digital model of porous titanium alloy plate implant with a specially open cellular three-dimensional structure, and the three-dimensional implant was prepared with Ti6Vl4V powder by using the 3D printing technology, following by titanium nitride coating on its articular surface. The degree of matching and attachment between the implant and acetabulum were observed; Ansys software was used for finite element modeling to analyze the stress distribution, stress conduction and deformation displacement of the acetabulum of the normal group, the traditional group and the implant group under the same load state, and to verify the biomechanical properties of the implant. RESULTS: The porous titanium alloy implant fit well with the acetabular bone defects, the shape of the plate was well attached to the bone surface, and it was rated as excellent according to the Matta criteria. The Von Mises stress peak of the implant group 13.38 MPa was close to the normal group 13.11 MPa and smaller than that in the traditional group 15.66 MPa. The Von Mises stress distribution and conduction of implant group were basically consistent with the normal group, slightly better than the traditional group; the maximum relative displacement of the implant was 0.166 mm, according to the finite element analysis. CONCLUSIONS: The porous titanium alloy stent plate implant with titanium nitride coating prepared by 3D technology has excellent matching degree and biomechanical properties; the anatomical reconstruction makes the stress distribution and conduction recovery well, close to normal hip joints, which provides a new option for the clinical treatment of comminuted posterior acetabular wall fractures with severe bone defects.

OBJECTIVE: To investigate the operative effect of PFNA combined with reconstructive locking plate on the treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall. METHODS: A total of 35 patients with comminuted femoral intertrochanteric fractures involving the lateral wall were surgically treated from November 2014 to January 2016. According to whether there was reconstruction of the lateral wall or not and the internal fixation method, the patients were divided into PFNA group (no reconstruction of the lateral wall), PFNA recontruction group (reconstructive locking plate was used to reconstruct the lateral wall, PFNA internal fixation). The clinical curative effect was evaluated by the analysis of operation time, intraoperative blood loss, postoperative activity time, the time of fracture healing, complications, and hip joint Harris score at 12 months after operation. RESULTS: All 35 patients completed the operation successfully. All the incisions were healed by first intention and no incision infection or fat liquefaction occurred. All 35 patients were followed up from 12 to 16 months with an average of 14.4 months. All patients had bone healing. There was no statistical significant in surgery time and intraoperative blood loss between two groups(P>0.05). There were 5 postoperative complications in the PFNA group and 1 in the PFNA combined with reconstructive locking plate group. There was a statistical difference between two groups(P<0.05). The postoperative activity time, bone healing time, complications, and Harris score of PFNA reconstruction group were all superior to PFNA group, there were statistically significant differences between two groups. CONCLUSIONS: Although the operation time and blood loss of PFNA combined with reconstructive locking plate in treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall are more than those in the PFNA group, and the surgical trauma is larger than PFNA, the fracture healing time, postoperative activity time, and hip joint function were all superior to those of the PFNA group, which can effectively shorten the postoperative bed rest time, and reduce bed complications as well as improve hip joint function.

Compared with the pediatric femoral neck fracture described by the Delbet-Colonna classification, femoral neck fracture with a comminuted posteromedial column is characterized by a more special fracture location. Therefore, it is more difficult to deal with, leading to higher incidences of avascular necrosis of femoral head, coxa vara deformity, and delayed union postoperatively. This paper reviews recent progress in diagnosis and treatment of this specific kind of fracture in the aspects of anatomy and function of the posteromedial column of the femoral neck, and special features, surgical treatment and complication avoidance concerning this fracture, hoping to arouse interest from pediatric surgeons in this specific fracture which has not been described by the Delbet-Colonna classification.
RESUMO
Objective:To compare the clinical outcomes between anatomical locking plate, proximal humerus internal locking system (PHILOS) and anatomical locking plate combined with suture anchors in the treatment of comminuted fractures of humeral greater tuberosity.Methods:A total of 33 comminuted fractures of humeral greater tuberosity were surgically treated from October 2016 to October 2021 at Department of Orthopedics, Tongji Hospital Affiliated to Tongji University. There were 20 males and 13 females, with an age of (53.5±13.6) years. They were assigned into 3 groups according to different internal fixation techniques. Group A of 12 cases was subjected to fixation with anatomical locking plate via the deltoid approach, group B of 10 cases subjected to fixation with PHILOS via the pectoralis major and the deltoid approaches and group C of 11 cases subjected to fixation with anatomical locking plate combined with suture anchors via the deltoid approach. The operation time, intraoperative blood loss, range of shoulder motion, Constant-Murley shoulder score, visual analogue scale (VAS) and postoperative complications were compared between the 3 groups.Results:The 3 groups were comparable because there was no significant difference between them in the general clinical data ( P>0.05). The follow-up duration for all patients was (14.5±4.1) months. All fractures got united at the last follow-up. In groups A, B and C, respectively, the operation time was (57.9±7.8), (73.0±7.1) and (63.6±9.5) min, and the intraoperative blood loss (41.7±18.9), (82.0±22.9) and (46.4±13.6) mL, showing significant differences between the 3 groups ( P<0.05). The operation time and intraoperative blood loss in groups A and C were significantly less than those in group B ( P< 0.05). At the last follow-up, in groups A, B and C, respectively, the shoulder abduction was 144.0°±7.7°, 138.7°±10.7° and 148.5°±6.2°, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). There was no statistically significant difference in the forward flexion, external rotation, or internal rotation of the shoulder joint between the 3 groups ( P>0.05). The Constant-Murley scores in groups A, B and C, respectively, were (90.4±5.7), (86.1±6.6) and (93.1±3.4) points, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). The VAS scores in groups A, B and C, respectively, were 1 (0, 2), 1 (0, 2), and 1 (0, 1) point, showing insignificant differences between the 3 groups ( P>0.05). Group A had 1 case of shoulder joint stiffness and 1 case of fracture re-displacement complicated with acromial impingement syndrome, group B 1 case of shoulder joint stiffness and 3 cases of fracture re-displacement, but group C no post-operative complication. Conclusions:In the treatment of comminuted fracture of humeral greater tuberosity, all the 3 internal fixation techniques can lead to fine clinical outcomes. Conventional PHILOS may lead to relatively large trauma and a high incidence of postoperative complications. The anatomical locking plate may result in fine functional recovery of the shoulder due to advantages of less invasion, shorter operation time and fewer postoperative complications than PHILOS. The anatomical locking plate combined with suture anchors may lead to the best shoulder functional recovery and the least complications.

OBJECTIVE: To explore the method and therapeutic effect of minor external fixation combined with Kirschner Treatment for open comminuted fracture of metacarpophalangeal joint. METHODS: From January 2013 to December 2014, 13 patients with open comminuted fracture of metacarpophalangeal joint were treated by minor external fixation combined with Kirschner wire, including 9 males and 4 females, aged from 18 to 56 years old with an average of 35 years old.According to Gustilo classification, 8 cases were type II, 4 cases were type IIIA, and 1 case was type IIIB. The time from injury to operation ranged from 2 to 7 h with an average of 5 h. All fractures were involved with metacarpal phalangeal joint surface. Fracture healing time and postoperative complications were observed, TAM scoring system by Hand Surgery Association of Chinese Medical Association was used to evaluate functional recovery. RESULTS: All patients were followed up from 3 to 12 months with an average of 7 months. All fractures were obtained bone healing, and the time ranged from 4 to 6 weeks with an average of (4.6±1.0) weeks. No broken and loose needle, pin track infections, malunion, loose bracket, reflection sexual sense of neurological malnutrition occurred. According to TAM scoring system, 7 cases obtained excellent results, 4 cases good, 1 case moderate and 1 case poor. CONCLUSIONS: Minor external fixation combined with Kirschner wire for open comminuted fracture of metacarpophalangeal joint has advantages of simple operation, good stability and which could be adjusted at the later stage, less damage for soft tissue periosteum, low inflammatory, earlier functional exercise. It is worth to be popularized and applied.

Objective:To evaluate the clinical results of miniplates combined with reconstruction plate in treating comminuted posterior wall acetabular fractures.Methods:A retrospective case series study was conducted for 27 patients with comminuted posterior wall acetabular fractures treated in General Hospital of Central Theatre Command of PLA from October 2015 to June 2019. There were 18 males and 9 females, at age of 23-61 years[(45.9±10.9)years]. All patients were treated by using miniplates combined with the reconstruction plate. The operation time, intraoperative blood loss, intraoperative blood transfusion, length of hospital stay and time of fracture healing were recorded. The reduction quality was evaluated according to Matta radiographic standard at 2 days postoperatively. The modified Merle D'Aubigné-Postel score was adopted to evaluate the hip function at 3, 6 months postoperatively and the final follow-up. Postoperative complications were observed, and heterotopic ossification was assessed by Brooker grading standard.Results:All patients were followed up for 12-48 months[36(24, 36)months]. The operation time was 123-242 minutes[(165.4±29.8)minutes]; the intraoperative blood loss was 170-550 ml[(358.3±111.3)ml]; nine patients required intraoperative blood transfusion of 300-500 ml[(377.8±66.7)ml]. The length of hospital stay was 12-29 days[(21.4±4.7)days]. The fracture healing time was 12-24 weeks[(16.3±3.0)weeks]. According to Matta radiographic standard, the reduction quality was excellent in 21 patients, good in 3 and poor in 3 at 2 days postoperatively, with the excellent rate of 89%. The modified Merle D'Aubigné-Postel score was 9-16 points[(13.1±1.9)points]at 3 months postoperatively, was 10-18 points[(15.4±2.0)points]at 6 months postoperatively, and was 12-18 points[(16.9±1.8)points]at last follow-up( P<0.01). The modified Merle D'Aubigné-Postel score between 3 months and 6 months was significantly different( P<0.01), and the difference between 6 months and the follow-up was statistically significant( P<0.01). The modified Merle D'Aubigné-Postel score was graded as excellent in 0 patient, good in 7, fair in 11 and poor in 9 at 3 months postoperatively, with the excellent rate of 26%; graded as excellent in 3 patients, good in 19, fair in 2 and poor in 3 at 6 months postoperatively, with the excellent rate of 81%; graded as excellent in 18 patients, good in 5, fair in 3 and poor in 1 at the last follow-up, with the excellent rate of 85%( P<0.01). No iatrogenic sciatic nerve injury, deep vein thrombosis or wound infection occurred after operation. No hardware loosening or loss of reduction occurred during the follow-up. The post-traumatic arthritis was identified in 2 patients. The avascular necrosis of femoral head was observed in 1 patient and thereafter underwent total hip replacement. The heterotopic ossification occurred in 3 patients, among which 2 patients were graded as Brooker class I and 1 as class II, but there was no adverse effect on hip function. Conclusions:Miniplates combined with reconstruction plate in the treatment of comminuted posterior wall acetabular fractures have reliable fixation effect and attain good reduction, high fracture healing rate, less complications and satisfactory functional recovery.
RESUMO
Objective:To explore the experience of the treatment of patella inferior pole fracture with non excitation tension band technique.Methods:From April 2009 to December 2019, 76 patients with inferior patellar fracture were treated with non excitation tension band technique. There were 42 males and 34 females; The age was 35.48 ± 18.12 years (17-66 years), with an average of 35 years. There were 45 cases on the left and 31 cases on the right. Causes of injury: fall injury in 46 cases, bicycle injury in 16 cases and traffic accident injury in 14 cases. The time from injury to operation was 0.25-5 d, with an average of 3.2 d. There were 18 cases of open fractures, 64 cases of articular surface fractures and 52 cases of comminuted fractures. Open fracture patients were debridement first, and all cases were fixed with non excitation tension band technique. The intraoperative fracture reduction, postoperative fracture healing and internal fixation were observed. The knee function was evaluated according to the degree of claudication, the use of supports, the feeling of joint strangulation, joint instability, pain, swelling, stair climbing and squatting.Results:All 76 patients successfully completed the operation and were followed up for 18.24 ± 6.18 months (range 12-24 months). There was no wire fracture during and after operation. All incisions healed in the first stage after operation, and there was no deep venous thrombosis of lower limbs. The X-ray film showed that there was no further fracture and fracture displacement after operation, and there was no Kirschner wire slip before the internal fixation was taken out. Only one case had steel wire relaxation due to buckle (which did not affect fracture healing). All fractures healed well, with an average of 7.5 weeks, and the fracture line basically disappeared. 12 months after operation, according to Lysholm knee score standard, the knee function of patients was evaluated. The score of 76 cases was 95.40±4.60 points (range 82-100 points): excellent in 54 cases, good in 21 cases and fair in 1 case. The excellent and good rate was 98.7%. According to the visual analogue scale (VAS) pain score standard, the patients were scored for postoperative pain. The score of 76 cases was 0.09±2.05 points (range 0-3 points): 4 cases had mild pain, with an average score of 0.09.Conclusion:The results of the treatment of patellar inferior pole fracture with tension free band technique are satisfactory, the pain caused by tissue irritation by the internal fixation was lower, clinical application can be popularized.
