OBJECTIVE: To explore the reduction and support effect of the subchondral screw compression technique for residual or secondary collapse of the lateral tibial plateau during operation. METHODS: Between January 2020 and June 2021, 11 patients with residual or secondary collapse of the lateral tibial plateau during operation were treated with the subchondral screw compression technique. There were 6 males and 5 females, aged 52.3 years old (range, 27-64 years). The fractures were caused by traffic accident in 10 cases and falling from height in 1 case and located at the left knee in 6 cases and the right knee in 5 cases. According to Schatzker classification, there were 5 cases of type Ⅱ fractures, 4 cases of type Ⅲ fractures, and 2 cases of type Ⅴfractures. According to the three columns classification, there were 5 cases of lateral column, 4 cases of lateral column and posterior column, and 2 cases of three columns. The time from injury to operation was 4.5 days (range, 3-7 days). During the follow-up, X-ray films were obtained and the Rasmussen standard was used to evaluate the quality of fracture reduction, meanwhile fracture healing was observed. The medial proximal tibial angle (mPTA), posterior tibial slope angle (pTSA), and articular surface collapse were measured at immediate and 12 months after operation. The knee joint range of motion was evaluated at last follow-up, and the knee joint function was evaluated using the Hospital for Special Surgery (HSS) score. RESULTS: All operations were successfully completed, with a mean operation time of 71.4 minutes (range, 55-120 minutes), and a mean hospital stay of 8.0 days (range, 5-13 days). The incisions all healed by first intention, without complications such as infection, flap necrosis, or vascular and nerve injury. All patients were followed up 16.5 months on average (range, 12-24 months). X-ray films showed that the fracture reduction score was 14-18 (mean, 16.7) according to Rasmussen score criteria; and 5 cases were rated as excellent and 6 as good. All fractures healed clinically with a mean clinical healing time of 14.9 weeks (range, 12-16 weeks), and there was no complications such as plate or screw loosening. At 12 months after operation, the mPTA and pTSA were (87.5±1.7)° and (6.2±3.1)°, respectively; there was no significant difference when compared to the values at immediate after operation [(87.6±1.8)° and (6.5±3.1)°] ( P>0.05). The articular surface of the tibial plateaus was effectively supported, and it collapsed again by 0-1.0 mm at 12 months, with an average of 0.4 mm. At last follow-up, the knee joint range of motion was 115°-135° (mean, 126.8°) and the HSS score for knee joint function was 87-98 (mean, 93.9). Five patients underwent secondary operation to remove the internal fixator at 12-18 months after operation. CONCLUSION The subchondral screw compression technique is helpful for the reduction of residual or secondary collapse of the lateral tibial plateau during operation, and can provide good support for osteochondral blocks.

OBJECTIVE: To investigate the effect of intramedullary nail fixation (IMN) and minimally invasive percutaneous plate internal fixation (MIPPO) techniques on tibiofibular fractures and their effect on platelet activation and serum transforming growth factor-β1 (TGF-β1) and bone morphogenetic protein-2 (BMP-2). METHODS: Total of 105 patients with tibiofibular fractures from February 2019 to February 2020 were selected and divided into 53 cases in the MIPPO group and 52 cases in the IMN group. There were 29 males and 24 females with an average age of (41.74±6.05) years old in MIPPO group;in IMN group, 31 males and 21 females with an average age of (40.59±5.26) years old. The perioperative surgical indexes, postoperative complications, ankle function recovery at 12 months postoperatively, platelet activation indexes at 3 and 7 days preoperatively and postoperatively, and serum TGF-β1 and BMP-2 levels at 4 and 8 weeks preoperatively and postoperatively were compared between the two groups. RESULTS: The operating time and fracture healing time in the MIPPO group were shorter than those in the IMN group(P<0.05); Compared with the preoperative period, the levels of GMP-140, PAC-1, CD63, and CD61 increased in both groups at 3 and 7 days after surgery, but were lower in the MIPPO group than in the IMN group(P<0.05);the levels of serum TGF-β1 and BMP-2 increased in both groups at 4 and 8 weeks after surgery compared with the preoperative period, and the postoperative complication rate in the MIPPO group was lower than that in the IMN group(P<0.05);the difference was not statistically significant in the excellent rate of ankle function recovery at 12 months follow-up after surgery between two groups(P>0.05). CONCLUSION Both intramedullary nail fixation and MIPO technique for treatment of tibia and fibula fractures can improve ankle joint function, but the latter has the advantages of short operation time, fast fracture healing, fewer complications, and light platelet activation. Serum TGF-β1, BMP-2 level improves quickly.

OBJECTIVE: To explore clinical effect of attaching locking plate with bone grafting based on retaining the original intramedullary nail in treating non-union after intramedullary nail fixation of long shaft fractures of lower limbs. METHODS: A retrospective study was conducted on 20 patients treated with non-union fractures after intramedullary nailing of long shaft fractures of lower limbs from June 2015 to June 2020. All patients were treated with the original intramedullary nailing and bone grafting from the iliac bone, and were underwent open reduction plate internal fixation and bone grafting for old fractures. Among them, 14 were males and 6 were females, aged from 35 to 56 years old with an average of (42.2±9.6) years old. Nine patients were femoral shaft fracture and 11 patients were tibial shaft fracture. According to characteristics of fracture end nonunion, 6 patients were stable/atrophic, 9 patients were unstable/large, and 5 patients were unstable/atrophic. The nonunion time ranged from 8 to 12 months with an average of(9.8±2.0) months after the initial surgery. Visual analogue scale (VAS), knee range of motion, bone healing time, complications and fracture-end healing were recorded before and at the latest follow-up. RESULTS: All patients were followed up for 18 to 48 months with an average of (36.3±10.5) months. The incision of all patients were healed at stageⅠwithout complications such as infection or internal fixation ruptur. Healing time of femur and tibia was (8.5±2.6) months and (9.5±2.2) months. Knee joint motion increased from preoperative (101.05±8.98) ° to postoperative (139.35±8.78) ° at the latest follow-up (t=-12.845, P<0.001). VAS decreased from preoperative (5.15±1.72) to postoperative (0.75±0.96) at the latest follow-up (t=11.186, P<0.001). CONCLUSION On the basis of retaining the original intramedullary nail, the addition of locking plate internal fixation and autogenous iliac bone grafting have advantages of simple operation, less trauma, fewer complications and high fracture healing rate. It is one of the effective surgical schemes for the treatment of nonunion after intramedullary nail fixation of long bone fracture of lower extremity.

PURPOSE: Electric scooters (e-scooters) have become an increasingly popular mode of public transportation in recent years. As the incidence of related injuries rises, it is important to understand specific fracture patterns unique to e-scooters and electric bikes (e-bikes) to help guide management. The purpose of this study was to review the prevalence and describe specific fracture patterns of e-scooter and e-bike related injuries at the busiest level 1 trauma center in the borough of Manhattan. METHODS: Chart review to determine mechanism of injury was performed on all patients for whom an orthopedic consult was requested from 1/1/2021 to 12/31/2021. All patients whose injuries were sustained due to an e-scooter or e-bike were further reviewed for demographics, injury characteristics including fracture pattern, and definitive injury management. Any patients who had an orthopedic consult placed for a reason other than an acute injury were excluded. Descriptive statistics are reported as frequency (percentage) for categorical variables and means for continuous variables. RESULTS: Of the 1815 orthopedic consults requested, 1357 (74.8%) were for acute injury management. Of those with acute injuries, 119 (8.8%) sustained 136 e-scooter or e-bike related injuries. There were 92 (77.3%) males at an average age of (33.8 ± 15.7) years. Approximately one-fifth of all patients presented in June 2021 (26, 21.8%). There was a 9.2% rate of open fractures. The 136 injuries were evenly split between the upper and lower extremities, with 57 (47.9%) upper extremity, 57 (47.9%) lower extremity injuries, and 5 (4.2%) concomitant upper and lower extremity injuries. The most common fracture patterns were ankle fractures (16, 11.7%), followed by tibial shaft (14, 10.2%), tibial plateau (13, 9.5%), and radial head fractures (11, 8.0%). There was a 33.3% incidence of associated posterior malleolar fractures in the spiral tibial shaft fractures, 31.0% of posterior malleolar involvement and 18.8% of isolated vertical medial malleolar fractures in the ankle fractures, and 61.5% of posterior comminution in the tibial plateau fractures. CONCLUSION E-scooter and e-bike related injuries have a high incidence of tibial shaft fractures, ankle fractures, tibial plateau fractures, and radial head fractures. There should be a high index of suspicion for posterior and medial involvement in lower extremity fractures sustained due to e-scooter or e-bikes. Identifying specific fracture patterns seen in e-scooter and e-bike related mechanisms will help guide management of these injuries.

PURPOSETo report complications in the management of complex closed proximal tibial fractures.

METHODA retrospective study was conducted to analyze the infectious and noninfectious complications encountered in the management of high-energy Schatzker type V and VI tibial plateau fractures. All patients were treated at the level 1 trauma centre between January 2011 and March 2014. Sixty two patients were included in the study. The mean patient age was (43.16 ± 11.59) years with 60 males and 2 females. Infectious complications like superficial and deep infection, wound dehiscence, malalignment in the immediate postoperative period and in follow-up period were noted.

RESULTSThe overall complication rate was 30.65% (19 out of 62). Infectious complications were noted in 20.97% cases (13/62). In majority of the cases (8/13), superficial infection was seen which managed with regular dressing and antibiotic administration. The patients (5/13) who had developed deep-seated infection were subjected to repeated debridements, flap coverage, implant removal or amputation depending upon the host response. Thirteen patients had experienced noninfectious complications. Hardware related complications were noticed in six patients and four among them received a secondary procedure. Malalignment was observed in seven patients but only single patient underwent subsequent operative intervention.

CONCLUSIONProximal tibial plateau fractures especially Shatzker type V and VI are associated with extensive soft tissue damage even in closed injuries. The complications encountered in the management of these fractures can be minimized with appropriate patient selection and minimal soft tissue dissection.

OBJECTIVETo investigate the clinical characteristics of Segond fracture combined with injuries, and to explore the operative method and opportunity.

METHODSFrom June 2010 to December 2014, 10 patients with Segond fracture were treated. There were 10 males, ranging in age from 26 to 69 years old, with a mean of 42 years old. Under arthroscopy examination within 7 to 10 days after injury, 6 patients had compete rupture of anterior cruciate ligament and meniscus injury; 2 patients had tibial avulsion fractures of the ACL combined with meniscus injury. At 4 to 8 weeks after injury, 2 patients were performed with arthroscopy examination; 1 patient had complete rupture of anterior and posterior cruciate ligament combined with meniscus injury; and the other patient had complete rupture of anterior cruciate ligament alone. All the patients with cruciate ligament rupture were treated with reconstruction of cruciate ligament; 9 patients had meniscus injuries were treated with menisus plasty or suture; and 2 patients had tibial avulsion fractures of the ACL were treated with non-absorbable Ethicon suture fixation under arthroscopy. After operation, the Lysholm scoring system was used to evaluate clinical effects.

RESULTSEight patients were operated within 10 days after injury, the knee joints swelling was obvious at the 3rd day after operation, and blood oozing was found by joint puncture. These 8 patients did out-of-bed activity with assistance at 1 week postoperatively. Other 2 patients performed operation in 4 to 8 weeks after injury without knee joint obvious swelling at the 3rd day after operation, and no blood oozing was found by joint puncture. These 2 patients did out-of-bed activity with assistance after 3 days postoperatively. All the patients were followed up, and the duration ranged from 12 to 24 months, with an average of 18 months. Postoperative Lysholm score of all patients was higher than preoperative scor, and the results were satisfactory.

CONCLUSIONFor Segond fractures, firstly, it is important to gain early diagnosis for treatment. Secondly, it is often associated with the rupture of anterior cruciate ligament and meniscus injuries, and the best time of cruciate ligament rebuilding and meniscus repairing maybe between 4 to 8 weeks after injury. Thirdly, personalized treatment should be chosen according to different complications.

OBJECTIVETo analyze the related factors of the infection after operation of open tibiofibula fractures.

METHODSThe clinical data of 141 patients with open tibiofibula fractures underwent surgical treatment from June 2009 to December 2012 were retrospectively analyzed. All the patients were male and aged from 18 to 61 years old with an average of 39.2 years; all the fractures were unilateral. According to Gustilo typing of fracure, 5 cases were type I, 44 cases were type II, 27 cases were type III a, 56 cases were type III b and 9 cases were type III c. These clinical data included patients' age, gender, body mass index (BMI), underlying diseases, time of operation, fracture site, fracture type, fixation method, postoperative drainage, debridement condition and so on. The postoperative infection conditions were recorded, and the correlation between above factors and infections were analyzed. Finally, the significant related variables were introduced into a Logistic regression model to evaluated their risk.

RESULTSAmong the 141 patients, 22 cases developed with infection (15.6%). The significant relative factors with infection contained fixation method, debridement condition, underlying diseases and postoperative drainage (P < 0.05). The correlativities were stepped up in order, their odds ratios value was 2.451, 3.164, 3.414, 5.117, respectively.

CONCLUSIONActive treatment for underlying diseases before operation, thorough debridement for open wound, suitable fixation method for fracture and thorough draining are effective measures in preventing postoperative infection.

A 30-year-old male was involved in a car accident. Radiographs revealed a depressed marginal fracture of the medial tibial plateau and an avulsion fracture of the fibular head. Magnetic resonance imaging showed avulsion fracture of Gerdy's tubercle, injury to the posterior cruciate ligament (PCL), posterior horn of the medial meniscus, and the attachments of the lateral collateral ligament and the biceps femoris tendon. The depressed fracture of the medial tibial plateau was elevated and stabilized using a cannulated screw and washer. The injured lateral and posterolateral corner (PLC) structures were repaired and augmented by PLC reconstruction. However, the avulsion fracture of Gerdy's tubercle was not fixed because it was minimally displaced and the torn PCL was also not repaired or reconstructed. We present a unique case of pure varus injury to the knee joint. This case contributes to our understanding of the mechanism of knee injury and provides insight regarding appropriate treatment plans for this type of injury.

OBJECTIVETo analysis the early complications of tibial fracture and its related factors, and propose a solution.

METHODSFrom December 2003 to December 2013,38 patients with early complications of tibial plateau fracture after operation were retrospectively analyzed. There were 35 males and 3 females, aged from 37 to 69 years old (averaged 42.3 years). According to Schatzker classification, 3 cases were classified as type II, 2 cases as type III, 2 cases as type IV, 19 cases as type V, 12 cases as type VI. The intervals between injury and operation ranged from 9 hours to 9 days, 26 cases within 3 days. Fifteen cases were treated with internal fixation of plates and 23 were treated by plate fixation and bone transplantation. Early complications included skin necrosis in 15 cases, infection in 6 cases, osteofascial compartment syndrome in 3 cases, common peroneal nerve injury in 2 cases, the superficial peroneal nerve injury in 3 cases, popliteal artery injury in 2 cases, loss of reduction in 7 cases.

RESULTSThe wound of 14 cases healed at the first stage and 24 cases healed delay. Hospitalization days ranged from 7 to 67 days (averaged 25.6 days). All patients were followed up for 12 to 36 months with an average of 16.4 months. The fracture healing time ranged from 3 to 9 months (averaged 6.9 months). According to Merchant knee function evaluation criteria, the results were excellent in 19 cases, good in 12, fair in 5 and poor in 2.

CONCLUSIONEarly complications of tibial fracture after operation is closely associated with the severe fracture complexity and related with preoperative preparation, surgical timing, operation incision selection and surgical technique. Early detection and timely processing reduce damage.
