Comparison of the MIPPO technique and the modified Stoppa approach in the treatment of unstable anterior pelvic ring injuries: a retrospective cohort study

BackgroundAnterior pelvic ring injuries have gradually become common. Using a minimally invasive technique to treat this injury may be feasible if the reduction and stability can be effectively achieved. We describe a percutaneous technique, minimally invasive percutaneous plate osteosynthesis (MIPPO), to fixate the anterior pelvis via establishing a subperiosteal tunnel between two limited incisions over the iliac crest(s) and pubic ramus in this research.MethodsA retrospective cohort study comparing the MIPPO technique (n = 60) versus the modified Stoppa approach (n = 53) for anterior pelvic ring injuries with posterior ring instability was performed from September 2016 to January 2023. The relative surgery variables, follow-up function evaluation, and complications were compared in two groups. The reduction quality of fracture was assessed according to the Matta criterion, and the functional score was evaluated using the Majeed score.ResultsAll patients completed follow-up, with an average interval of 39.90 ± 17.53 months (range 12–78). In the MIPPO technique group, the surgery interval and blood losses were lower compared to the modified Stoppa approach group (P<0.05). The mean procedure times and intraoperative blood losses were 69.56 ± 14.04 min/side (range 50–110) and 156.23 ± 49.75 mL/side (range 90–250) for unilateral anterior ring MIPPO fixation separately. All patients got a satisfactory reduction of the fracture. In the follow-up, earlier ambulation, shorter postoperative hospital stays, and lower complication rates were observed for patients using the MIPPO technique compared to the modified Stoppa approach (P<0.05). However, there is no statistical difference in these indicators including fracture union interval, full load time, the Majeed score, patient satisfaction level, and return to pre-injured work rate between the two groups.ConclusionThis clinical experience gives support for the use of the MIPPO technique to stabilize the anterior pelvis. This minimally invasive technique was an effective and safe surgery method and could obtain satisfactory function results, particularly fitting to part of patients with resistance using the modified Stoppa approach.

Functional Outcomes of Distal Tibia Fractures Treated With Minimally Invasive Percutaneous Plate Osteosynthesis (MIPPO).

The tibia, a crucial long bone in the lower leg, plays a vital role in supporting mobility. Distal tibial fractures (DTFs) are relatively uncommon amonglower extremity fractures. Minimally invasive percutaneous plate osteosynthesis (MIPPO) has become increasingly popular due to advancements in surgicaltechniques and its potential for positive clinical outcomes. To evaluate the functional outcomes and complication rates of closed DTFs treated with MIPPOin adult patients, and to assess the impact of factors such as age, injury mechanism, and fracture classification on the treatment results. A retrospective study was conducted in the Department of Orthopedic Surgery at Sheikh Zayed Medical College Rahim Yar Khan, Pakistan from January 1, 2022, to December 31, 2022. Seventy patients, aged 18 to 60 years, were included. Postoperative follow-up assessments were conducted at six weeks, three months, and six months to evaluate functional outcomes. The majority of patients were male, with a mean age of 34 years. The most frequent cause of injury was road traffic accidents, followed by falls from height and other causes. Fractures were classified into three types: A1, A2, and A3. Functional outcomes at the final follow-up showed most patients had excellent to satisfactory results, while a smaller proportion had fair to poor outcomes. A few patients experienced postoperative complications, including malunion, infection, and ankle stiffness. The study suggests that MIPPO is an effective surgical technique for managing DTFs, providing favourable functional outcomes with a relatively low complication rate. Therefore, MIPPO can be considered a valuable option in treating these fractures.

Combining robotics and 3D printing facilitates closed reduction of humeral shaft fractures using a minimally invasive plate as a reduction template: A proof-of-concept study.

Minimally invasive percutaneous plate osteosynthesis for humeral shaft fractures (HSFs) has limitations due to malreduction and radiation exposure. To address these limitations, we integrated robotics and 3D printing by incorporating plates as reduction templates. The innovative technology facilitated closed reduction of HSFs in the operating theatre using 18 models with cortical marking holes. The dataset of the precontoured plate was imported into 3D planning software for virtual fixation and screw path planning. The models were divided into half to simulate transverse fractures. During the operation, the software generated drilling trajectories for robot navigation, and precise plate installation achieved automatic fracture reduction. The evaluation results of reduction accuracy revealed variations in length, apposition, alignment, and rotation that meet the criteria for anatomic reduction. High interoperator reliabilities were observed for all parameters. The proposed technology achieved anatomic reduction in simulated bones.

FUNCTIONAL OUTCOME OF MINIMALLY INVASIVE PERCUTANEOUS PLATE OSTEOSYNTHESIS AMONG PATIENTS WITH PROXIMAL TIBIA FRACTURES

Proximal tibia fractures are complex injuries that pose significant challenges in orthopaedic surgery. Minimally invasive percutaneous plate osteosynthesis (MIPPO) has been increasingly adopted as a treatment method due to its potential benefits in reducing soft tissue damage and promoting faster recovery. Objective: To assess the functional outcome of minimally invasive percutaneous plate osteosynthesis (MIPPO) among patients with proximal tibia fractures. Methods: A prospective cohort study was conducted in a tertiary care hospital over a period of two years, from January 2021 to December 2022. Thirty-five patients presenting with proximal tibia fractures were treated using the MIPPO technique. The Schatzker classification was used to categorize the fractures. Functional outcomes were assessed using the Knee Society Score (KSS) at six months postoperatively. Data were analyzed using descriptive statistics and chi-square tests to determine the significance of outcomes. Results: The most frequent type of fracture, according to Schatzker's classification, was type I, followed by type II and type III. An excellent outcome was observed in 21 patients (60%), good outcomes in 8 patients (22.9%), fair outcomes in 5 patients (14.3%), and poor outcomes in 1 patient (2.9%). Postoperative complications included infection in 2 patients (5.7%). Conclusion: Minimally invasive percutaneous plate osteosynthesis (MIPPO) is a safe and effective technique for managing proximal tibia fractures, yielding excellent functional outcomes in most patients.

A Dilemma in the Management of Distal Tibia Fractures Solved by Minimally Invasive Percutaneous Plate Osteosynthesis Technique: A Prospective Study.

Introduction Managing distal tibia fractures is challenging for trauma surgeons because of their peculiar anatomy with less soft tissue coverage and poor blood supply. There are various treatment options for distal tibia fractures such as open reduction and plating, minimally invasive percutaneous plate osteosynthesis, and intramedullary interlocking nailing. Open reduction and internal fixation can lead to excessive soft tissue dissection and devascularization of fracture fragments. We conducted a study on the functional outcome of distal tibia fractures treated by biological fixation with minimally invasive percutaneous plate osteosynthesis. Methods A total of 23 patients with distal one-third tibia fractures, fulfilling the inclusion criteria, who were treated at St. John's Medical College Hospital with minimally invasive percutaneous plate osteosynthesis between November 2020 and November 2022 were studied using the American Orthopaedic Foot & Ankle Society (AOFAS) score at six weeks, three months, and six months postoperative follow-up. Results This study included 17 males and six females. The mean age of the study participants was 43.78 years, with most of the participants being in the age group between 51 and 60 years (29.2%, n = 7). All the study participants were employed. The mean operative time was two hours and 10 minutes. The mean duration for the radiological union was 22 weeks. The mean AOFAS score at six months was 92.43 + 5.696. There was only one case of superficial infection, which was treated with intravenous antibiotics. There were no cases of malunion/nonunion. Conclusion Minimally invasive percutaneous plate osteosynthesis is an effective treatment for distal tibia fractures avoiding most of the complications such as wound dehiscence and malunion/nonunion involved in conventional open reduction and internal fixation with plating. Therefore, we recommend this technique for all distal tibia fractures.

Optimizing Surgical Management of Tibial Plateau Fractures: A Comparative Study of Minimally Invasive Versus Open Reduction Techniques.

Tibial plateau fractures pose a significant challenge to orthopedic surgeons due to their complex nature and potential for long-term morbidity. Surgical intervention is often necessary to restore anatomical alignment and optimize functional outcomes. This study aimed to evaluate the efficacy of minimally invasive percutaneous plate osteosynthesis (MIPPO) compared to open reduction and internal fixation (ORIF) in the management of tibial plateau fractures. The present hospital-based observational study was conducted at Agartala Government Medical College for two years. Seventy adult patients with tibial plateau fractures were included, with surgical interventions performed based on fracture characteristics. Postoperative outcomes, including knee range of movements, functional recovery, and complication rates, were assessed at six months. MIPPO demonstrated superior outcomes compared to ORIF, with a higher proportion of participants achieving knee range of movements > 120 degrees (66.7% versus 36%; p = 0.030), excellent functional outcomes (66.7%versus 36%; p = 0.046), and lower postoperative complication rates (2.2% versus28%; p = 0.001). Fracture union times were significantly shorter in MIPPO (12.49 weeks) when compared to ORIF (14 weeks) (p = 0.009). MIPPO offers advantages over conventional ORIF in terms of functional recovery and complication rateswhile demonstrating comparable fracture union times. These findings advocate for the adoption of MIPPO as a preferred surgical technique for tibial plateau fractures.

3D printing assisted MIPO for treatment of complex middle-proximal humeral shaft fractures

BackgroundThis study was designed to explore the clinical efficacy of 3-dimensional (3D) printing assisted minimally invasive percutaneous plate osteosynthesis (MIPO) technique by comparing the clinical outcomes with traditional open reduction and internal plating fixation (ORIF) for treating complex middle-proximal humerus fractures (AO 12C fracture type).Materials and methodsThe data of 42 participants who received a complicated middle-proximal humerus fracture from the beginning of 2018 to the end of 2022 were retrospectively analyzed. All patients were assigned to two groups: MIPO with detailed preoperative planning assisted by 3D printing technique (MIPO group), and traditional ORIF (ORIF group).ResultsThis study included 21 patients in the ORIF group and 21 patients in the MIPO group. All patients were followed-up for at least one year (mean: 16.12 ± 4.13 months), and no difference was observed in the range of shoulder joint motion (ROM), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores and Constant scores between the two groups. However, the occurrence of complications (surgical incision site infection, implant loosening, bone nonunion and radial nerve palsy) in ORIF group was remarkably higher compared to the MIPO group. All the cases achieved bone union within the MIPO group. Significant differences were found in surgical time, intraoperative blood loss and fracture healing time between the two groups.ConclusionPreoperative 3D printing assisted MIPO technique exhibits obvious advantages in high operational efficiency and low occurrence of complications, which is worthy of clinical application for treating complex middle-proximal humeral shaft fractures.

A novel technology integrating robotics and 3D printing for closed reduction of tibia shaft fracture with MIPPO:A proof-of-concept study

Less invasive fixation techniques, such as intramedullary nailing (IMN) and minimally invasive percutaneous plate osteosynthesis (MIPPO), are now the preferred choices for treating tibia shaft fractures (TSFs). However, malreduction and radiation exposure are the main deficiencies associated with less invasive fixation techniques, especially when assessing rotation around the shaft axis intra-operatively. The purpose of this study was to investigate the feasibility and reduction accuracy of an innovative technology that integrates robotics and 3D printing for achieving anatomical reduction of TSFs with MIPPO. The surgical workflow from a standardized CT protocol, via 3D reconstruction, 3D printing tibia model, pre-contouring plate, 3D scanning plate, 3D planning of the trajectories of the robot, and use of a commercial surgical robot, robot-assisted screw hole drilling, to automatic fracture reduction through precise installation of the plate was described. The reduction accuracy was evaluated by an optical tracking system. The mean variations of 1.95 ± 1.36mm in length, 1.63 ± 0.92 mm in apposition, 2.78 ± 1.69° in alignment, and 1.99 ± 1.81° in rotation. The interoperator reliabilities were almost perfect, with values of 0.91, 0.93, 0.92, and 0.90, respectively. The proposed technology achieved anatomic reduction on phantom bones.

Comparing Minimally Invasive Percutaneous Plate Osteosynthesis With Interlocking Intramedullary Nail Fixation for the Management of Adult Extra-Articular Distal Tibial Fractures: A Comprehensive Systematic Review and Meta-Analysis.

Intramedullary nailing (IMN) and minimally invasive percutaneous plate osteosynthesis (MIPPO) fixation are both viable approaches for managing distal tibia fractures. IM nailing offers advantages in terms of shorter operation time, faster union, and reduced infection rates, yet it may lead to alignment issues and residual knee pain. Conversely, MIPPO fixation provides better alignment and minimizes knee discomfort but comes with a higher risk of soft-tissue complications and hardware irritation. Notably, this review reveals that MIPPO is associated with a greater risk of both superficial (15% vs. 7% for IMN) and deep infections (14% vs. 6.3% for IMN). This study aims to comprehensively assess the optimal surgical approaches for distal tibia fractures by comparing clinical and functional outcomes between MIPPOand interlocking IMNtechniques in treating extra-articular distal tibial fractures. Key outcome parameters include operation duration, union time, non-union occurrence, malunion cases, infection rates, secondary surgical interventions, and functional results, as indicated by quality of life and ankle scores. Regarding union complications, it is notable that IMN demonstrates a higher incidence of malunion, affecting 14.7% of patients compared to 8.8% in the MIPPO fixation group. Interestingly, both treatment methods exhibit a similar incidence of non-union, occurring in 3.5% of patients in both groups. Furthermore, when assessing the union time, IMN fixation notably achieves significantly shorter union times, especially evident in AO 43A fracture types and closed fractures. The mean time for union is 18 weeks with IMN compared to 20 weeks with MIPPO fixation. In our analysis of nine studies involving 813 patients, the reported operation times revealed an overall weighted mean operation time of 74.1 minutes (ranging from 56.4 to 124 minutes) for IMN and 85.4 minutes (ranging from 51.4 to 124 minutes) for MIPPO fixation. Notably, the operation time for IMN was significantly shorter compared to MIPPO, showing a weighted mean difference (WMD) of -11.24 minutes, with a 95% confidence interval (CI) ranging from -15.44 to -7.05 (P<0.05). This difference exhibited significant moderate heterogeneity (I2 = 68%). In light of this comprehensive study, both MIPPO and IMN emerge as equally effective therapeutic options for addressing functional outcomes in distal tibial extra-articular fractures. While IMN offers several advantages, including lower infection rates, reduced implant irritation, shorter operation time, and earlier weight-bearing and union, it is associated with a heightened risk of malunion and anterior knee pain. Consequently, the choice of implant should be tailored on a case-by-case basis. Patients at elevated infection risk, stemming from factors, such as advanced age, comorbidities, smoking, or severe soft tissue injuries, are better suited for nail treatment. Conversely, MIPPO fixation may present a more advantageous choice for young, active, and healthy patients, given its ability to mitigate the risk of knee pain and malunion.

Comparative Study of Intramedullary Interlocking Nailing and Minimally Invasive Percutaneous Plate Osteosynthesis for Distal Tibia Extra-Articular Fractures

Management of distal tibial extra-articular fractures presents a significant challenge in orthopedic practice due to their complex anatomical features and variable fracture patterns. Surgical intervention plays a crucial role in achieving stable fixation and optimal functional outcomes. This study aimed to compare the effectiveness between minimally invasive percutaneous plate osteosynthesis and intramedullary nailing for the management of distal tibial extra-articular fractures. This was a prospective observational study that was conducted in the Department of Orthopedics, Bangabandhu Sheikh Mujib Medical College, Hospital (BSMMCH), Faridpur, Bangladesh from January 2021 to December 2022. Total 24 patients having a fracture of the distal third of the tibia were enrolled in this study as the study subjects. Total patients were divided into two groups. In group A, 12 patients underwent minimally invasive percutaneous plate osteosynthesis (MIPPO) and in group B, 12 patients underwent intramedullary nailing (IMN). A random selection method was used in sample selection. According to Olerud Molander’s score, Excellent, Good and Fair results were found in 50%, 50%, and 0% of the group A patients respectively. On the other hand, those results were found in 42%, 50% and 8% of group B patients respectively. Although both minimally invasive percutaneous plate osteosynthesis and intramedullary nailing procedures are effective in managing distal tibial extra-articular fractures, considering excellent union rate, low blood loss and remarkable Olerud Molander’s score, MIPPO may be considered as the better option.

Comparison of clinical efficacy between closed reduction combined with semi-circular external fixator and minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of middle and distal tibia fractures

To compare the clinical efficacy between closed reduction combined with semi-circular external fixator and minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of middle anddistal tibia fractures. The clinical data of sixty patients with middle and distal tibia fractures admitted between January 2019 and November 2022, were retrospectively analyzed. These patients were categorized into external fixation group (n=30) and internal fixation group (n=30). There were 18 males and 12 females in the external fixation group, with an average age of (49.29±2.35) years old. Among them, 14 patients presented with fractures on the left side, and 16 patients presented with fractures on the right side. Closed reduction, arched wire, and semi-circular external fixator were used for treatment. There were 20 males and 10 females in the internal fixation group, with an average age of (48.96±1.87) years old. Among them, 15 patients presented with fractures on the left side, and 15 patients presented with fractures on the right side. MIPPO technique was used for the treatment. Perioperative parameters, including time injury to surgery, surgical duration, incision length, intraoperative bleeding, time to active activity, and incision healing level, were compared between the two groups. Clinical outcomes were also assessed, including Johner-Wruhs scores, time to minimum pain-adapted full weight-bearing, visual analog scale (VAS), SF-36 scale, and complications. The external fixation group exhibited a significantly shorter incision length (1.36±0.86) cm and lower intraoperative bleeding (10.83±5.73) ml compared to the internal fixation group (12.74±3.12) cm and (86.47±8.90) ml, respectively(P<0.05). The postoperative active activity time (1.50±0.54) days and minimum pain-adapted full weight-bearing activity time(108.87±3.43) days in the external fixation group were slightly delayed than the internal fixation group(1.15±0.98) days and (105.27±3.68) days, respectively(P<0.05). Over a mean postoperative follow-up duration of (6.23±1.89) months, both groups showed improved VAS and SF-36 scale scores. There were no statistically significant differences in VAS and SF-36 scale scores 1, 3, 6 months post-operatively between the two groups(P>0.05). The intraoperative surgical time in the external fixation group (35.42±9.31) minutes was shorter than that in the internal fixation group(74.22±7.81) minutes (P<0.05). There was no intraoperative vascular or nerve injury, nor postoperative skin necrosis in the external fixation group. However, skin necrosis was observed in 6 patientsin the internal fixation group, representing a statistically significant difference (P<0.05). Both external fixation and plate internal fixation are effective methods for the treatment of middle and distal tibia fractures. External fixation exhibits the advantage of less surgical trauma and a lower incidence of complications.

A Review of Tibial Shaft Fracture Fixation Methods

Tibial shaft fractures are a commonly seen injury in orthopedic trauma patients. Fractures commonly occur following high energy mechanisms, such as motor vehicle collisions. There are multiple ways to stabilize tibial shaft fractures. Knowledge of the indications, contraindications, techniques, and complications associated with each technique allows the orthopedic surgeon to make the appropriate decision for each patient by providing both fracture and patient characteristics. This review discusses the indications, techniques, outcomes, and complications associated with intramedullary nailing, minimally invasive percutaneous plate osteosynthesis, and external fixation of tibial shaft fractures.

Distal Tibial Fractures – Surgical Outcome Following Minimally Invasive Percutaneous Plate Osteosynthesis

Objectives With preservation of the vascularity of the bone, preservation of the soft tissue envelope and containment of the fracture haematoma, minimally invasive procedures provide fixation in a biologically sound manner. With these in view, this study was conducted to evaluate the technique of surgical management in distal tibial fractures treated by internal fixation with locking compression plate (LCP) and screws through the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique. Material and Methods In this cohort study, 21 patients with distal tibial fractures who were admitted to the hospital between November 2014 and August 2016 were tracked for at least 10 weeks and up to 39 weeks. Adults who were fit enough for surgery, both male and female, participated in the study. MIPPO procedures were followed for every case. In this investigation, a total of 21 cases were examined. Results 86% of cases with proper bone union were able to bear their full weight at or before the 18-week mark. Complete weight bearing was permitted for the final three patients (14%) at or before 39 weeks. Ninety per cent of patients had fracture union rates that were satisfactory to excellent at 23 weeks. Also, delayed unions were noted in three individuals; two cases experienced ankle stiffness, one as a result of prolonged immobilization and the other as a result of an intra-articular fracture. There were no infections or wound breakdowns during this trial. Conclusion The MIPPO technique with LCP plates is a good choice when intramedullary nailing is inadequate for metaphyseal and distal tibia shaft fractures. Also, early fracture union is easily accomplished using the MIPPO technique and careful application of these plates.

Minimally Invasive Percutaneous Plate Osteosynthesis versus Interlocking Intramedullary Nail Fixation in Treating Extra-Articular Distal Tibial Fractures in Adults. A Systematic Review

Background IM nailing and MIPPO fixation remain viable options for management of distal tibia fractures. IM nailing provides superior operation time, union time, and time to full weight-bearing as well as a lower incidence of superficial and deep infection, but may provide inferior alignment and is associated with residual knee pain. MIPPO fixation provides superior alignment and avoids knee pain, but it has a higher rate of soft-tissue complications and hardware irritation. This review revealed that MIPPO has a higher risk of both superficial and deep infection among patients treated with MIPPO compared to IMN. In the MIPPO technique, 15% developed a superficial infection, compared to 7% after IMN, and 14% developed a deep infection, compared to 6.3% after IMN. Aim of the Work to provide a complete overview of the optimal surgical treatment of distal tibia fractures by evaluating and comparing the clinical and functional outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) vs Interlocking intramedullary nail (IMN) for treating extra-articular distal tibial fractures. Outcomes of interest include operation time, time to union, non-union, mal-union, infection, secondary operations, and functional outcomes (quality of life scores and ankle scores). Patients and Methods In terms of union complication, IMN has a higher incidence of malunion which occurred in 14.7% of the patients after IMN compared to 8.8% after MIPPO fixation. The incidence of non-union was similar in both treatment methods, it occurred in 3.5% of patients. In addition to union rate, the union time was significantly shorter after IMN fixation compared to the MIPPO technique especially in AO 43A fracture type and the closed fractures. The mean time for union was 18 weeks in IMN compared to 20 weeks in MIPPO. Results Nine studies including 813 patients reported on operation time with an overall weighted mean operation time of 74.1 minutes (range 56.4 – 124 minutes) in IMN and 85.4 minutes (range 51.4 – 124 minutes) in MIPPO. The operation time in the IMN was significantly shorter compared to MIPPO (WMD -11.24 minutes, 95% CI -15.44 to -7.05, P &amp;lt; 0.05) with significant moderate heterogeneity (I2 = 68%). Conclusion Based on this study, both MIPPO and IMN have similar therapeutic efficacy regarding the functional outcome and can be used safely in distal tibial extra-articular fractures. Although IMN is advantageous over MIPPO with a lower incidence of infection and implant irritation symptoms, shorter operation time, earlier weight-bearing, and earlier union, it leads to a higher rate of mal-union and anterior knee pain. Overall, choosing an implant based on the findings of this meta-analysis is difficult and should be done on a caseby-case basis. Patients who have a high risk for infection (due to high age, comorbidities, smoking, or severe soft tissue injury) should preferably be treated with a nail. MIPPO fixation may be more beneficial to young, active, and healthy patients who are less prone to infection because it reduces the risk of knee pain and mal-union.

Application of bridge-link type combined fixation system in the treatment of trifocal femoral fractures.

Ipsilateral combined fractures of the proximal femur, femoral shaft, and distal femur, though uncommon, present significant treatment challenges for orthopaedic surgeons. This retrospective study aims to investigate the intraoperative and long-term postoperative outcomes of this combination fracture when treated using a bridge-link type combined fixation system (BCFS). Four individuals received treatment at a level 1 trauma centre between January 2013 and December 2017 for combined fractures of the proximal femur, femoral shaft, and distal femur. The medical records of these patients were retrospectively examined. In addition to minimally invasive percutaneous plate osteosynthesis (MIO), all patients underwent BCFS. The median follow-up period for each patient was 28.5 months. The median duration of the surgical procedure was 176.0 min, with intraoperative haemorrhage measured at 470.0 ml. Among the cases, three patients showed firm union of the femoral shaft fractures. However, one patient experienced nonunion 12 months after the procedure, while another patient suffered from refracture of the femoral shaft and postoperative avascular necrosis of the femoral head. At the time of the last follow-up, the Friedman-Wyman functional scores were excellent in one case, good in two cases, and fair in one case. Trifocal femoral fractures lack a widely approved therapeutic strategy. Nonetheless, BCFS may present itself as a viable alternative for treating this type of fracture, offering positive clinical outcomes.

Medial minimally invasive percutaneous plate osteosynthesis for humeral shaft fractures: a case series and novel technique description.

Minimally Invasive Percutaneous Plate Osteosynthesis (MIPPO) is increasingly favored for treating humeral shaft fractures (HSFs). However, conventional MIPPO techniques pose challenges in fixing fractures near fossa olecranon and carry a risk of iatrogenic radial nerve palsy. A novel technique using a medial MIPPO for treating humeral shaft fractures (HSFs) is described. Results of clinical follow-up are presented. This study is a retrospective case series study. Twenty-one patients (mean age 43.9 ± 17.66 [22‒81] years) with HSFs were treated with the novel MIPPO fixation method. Clinical outcomes including time for radiographic consolidation, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and complications were assessed at the last follow-up. The mean follow-up was 26 ± 17.12 (range 12-67) months. All patients had a bony union at a mean of 15.76 ± 6.74 (range 8-40) weeks based on X-ray with an early and aggressive range of motion. The complication rate was 0. The mean DASH score was3.29 ± 4.09 (range 0-14.17) at the time of the last follow-up. The mean screw density was 0.49 ± 0.1 (range 0.2-0.65). This novel surgical technique for HSFs is a viable alternative to previously described methods with the advantage of being less prone to nerve injury and easy to fix distal extra-articular HSFs. The learning curve is short. IV.

Development and clinical application of a new reduction device for the treatment of tibial plateau fracture under arthroscopic monitoring

To develop a reduction device for the arthroscopy-assisted treatment of tibial plateau fracture and explore its clinical efficacy. From May 2018 to September 2019, 21 patients with tibial plateau fracture were treated, including 17 males and 4 females. Their ages ranged from 18 to 55 years old with an average of (38.6±8.7) years old. There were 5 cases of Schatzker typeⅡand 16 cases of Schatzker type Ⅲ. The self-designed reductor combined with arthroscope was used for auxiliary reduction and fixation(minimally invasive percutaneous plate osteosynthesis). The efficacy was analyzed by observing the operation time, blood loss, fracture healing time and knee function(HSS and IKDC scoring criteria). All the 21 patients were followed up for 8 to 24 with an average of(14.0±3.1) months. The operative time ranged from 70 to 95 min with an average of(81.7±7.6)min, incision length ranged from 4 to 7 cm with an average of(5.3±0.9) cm, intraoperative blood loss ranged from 20 to 50 ml with an average of(35.3±5.2) ml, postoperative weight-bearing time ranged from 30 to 50 d with an average of(35.1±9.2) d, fracture healing time ranged from 65 to 90 d with an average of(75.0±4.4) d, and complications were 0 cases, respectively. The fracture was well healed and no screw plate fracture was observed. The knee function scores of HSS and IKDC 18 months after operation were significantly higher than those before operation(P<0.05). The custom-made reduction tool for the arthroscopic management of tibial plateau fracture is reasonable in design and simple in operation. The specific reduction tool could effectively reduce the fracture, and shorten the fixation time with minimally invasive procedure.

Minimally Invasive Percutaneous Plate Osteosynthesis (MIPO) for Distal Tibial Metaphyseal Fracture: A Better Option

Objective: The objective of this study was to evaluate the radiological and functional outcomes in of treatment of fracture distal tibial metaphysis fixed with pre-contoured anatomical locking compression plate using minimally invasive percutaneous plate osteosynthesis (MIPO) technique. Methods: This was a prospective study conducted at Department of Orthopedic Surgery, Services Hospital Lahore. Total of 58 closed distal tibial metaphyseal fractures (AO classification 43A) included in the study. All patients were operated using anatomical LCP with MIPO technique. The functional outcome was assessed by Tenny &amp; Wiss criteria at 6 weekly intervals with final scoring at 24th week. Functional outcome was graded as excellent, good, fair and poor. Similarly, radiological outcome was also assessed at 6 week intervals using Hammer et al criteria and grade 3 labelled as union. Results: We observed excellent functional outcome in 48 patients (82.6%) and good outcome in 6(10.34%) at last follow-up. Radiological union was achieved in 100% (58) patients at 24th week. The average time of union was 16.5 weeks with a range of 12 to 23 weeks. Total 03 patients (5.17%) developed superficial wound infection which was successfully managed with antibiotic therapy and no surgical site deep infection reported. Conclusion: Results of this study advocate that treatment of distal tibial metaphyseal fractures with LCP by MIPPO technique is an effective modality resulting in low complication rate, high union rates and good functional outcome.

A retrospective comparison of double-hooked locking plates versus non-locking plates in minimally invasive percutaneous plate osteosynthesis for the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures

BackgroundSurgical approach and fixation material are crucial in the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures. This study compared the efficacy of double-hooked locking plates and anatomic plates in minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures.MethodsClinical data were collected from 96 patients diagnosed with comminuted distal fibular fractures accompanied by tibial Pilon fractures who had undergone MIPPO. Patients in the study group (n = 48) received double-hooked locking plate fixations and the control group (n = 48) received anatomical plate fixations. The operating time, intraoperative bleeding, length of hospital stays, full weight-bearing time, fracture healing time and complication rates in the two groups were compared. The quality of fracture reduction was evaluated using the Burwell–Chamley imaging scoring system; the ankle function was assessed based on the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score.ResultsPatients in the study group had shorter operating time, less bleeding, significantly shorter hospital stays, and shorter time to full weight-bearing as well as fracture healing compared to the control group (P < 0.05). Additionally, the post-operative complication rates were significantly lower in the study group (6.16% vs. 22.92%) (P < 0.05), but there was no significant difference in the fracture reduction rate between the two groups (P > 0.05). Patients in the study group experienced better ankle recovery than those in the control group (93.75% vs. 75.00%) (P < 0.05).ConclusionDouble-hooked locking plates have advantages in the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures during MIPPO due to their shorter operating time and less intraoperative bleeding, as well as shorter hospital stays, full weight-bearing time and fracture healing time, fewer complications and better ankle recovery. Therefore, double-hooked locking plates are worthy of clinical application.

FUNCTIONAL AND RADIOLOGICAL OUTCOME OF LOWER THIRD TIBIAL FRACTURES IN ADULTS TREATED BY MIPPO WITH LOCKING COMPRESSION PLATE - A PROSPECTIVE STUDY

Background: Treating distal tibia fractures can be challenging because of the limited soft tissue available at this region, the subcutaneous location of the bone , precarious blood supply and its close proximity to ankle joint. Treatment for fractures of distal tibia remains a controversial subject despite an ample amount of advances in both non-surgical (conservative) and operative care. This is a prospective study Material And Methods: to analyse the functional and radiological outcome of xing the distal third of tibia treated with Minimally Invasive Percutaneous Plate Osteosynthesis (MIPPO). 30 patients were treated for extra articular dista Results: l third tibia fracture with MIPPO. In our study all 30 patients achieved radiological union at a mean time of 15.6 weeks. 94% had excellent to good objective results based on AOFAS criteria and 97% had excellent subjective criteria. We observed ankle joint stiffness in 2 patients and 3 had supercial infection. Treating the closed distal Conclusion: third tibial fractures with LCP with MIPPO technique provides an early union and excellent to good functional outcome
