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.

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.

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.

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.

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.

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

3D mirror printing combined with minimally invasive percutaneous plate osteosynthesis in the treatment of adult median clavicle fracture

To retrospectively analyze clinical effect of 3D mirror printing combining with minimally invasive percutaneous plate osteosynthesis(MIPPO) technology in the treatment of adult clavicle fracture. The clinical data of 32 adult patients with collarbone AllmanⅠdisplacement of fracture who had undergone the combination of 3D mirror printing with MIPPO technology treatment were collected from October 2019 to October 2020. There were 19 males and 13 females, aged from 19 to 55 years old with an average of(34.12±16.42) years old. According to Allman classification, there were 14 cases of AllmanⅠb and 18 cases of AllmanⅠc. Fracture occurred on the left in 17 cases and on the right in 15 cases. Postoperative complications, operation time, incision length, intraoperative blood loss, the number of fluoroscopies, fracture healing time of all patients were retrospectively analyzed, and the curative effect was evaluated by Constant-Murley shoulder joint score before operation, 1 and 6 months after operation. All the 32 patients were followed up for 6 to 8 months, with an average of (6.67±2.13) months. All the patients did not have postoperative complications such as incision infection and skin numbness in the operating area. The operation time was (35.37±4.28) min. The incision length was (3.78±0.45) cm. Intraoperative blood loss was(37.23±4.76) ml. The number of fluoroscopies was(3.12±0.47) times. Fracture healing time was (8.18±2.58) weeks. Constant-Murley shoulder joint score of the affected side at 1 and 6 months after operation was 81.08±3.92 and 98.03±1.05 respectively, which had a significant difference compared with 54.62±5.25 before operation(P<0.05). According to Constant-Murley shoulder function score at 6 months after operation, 30 cases were excellent and 2 cases were good. 3D mirror printing can effectively assist MIPPO technique in the treatment of adult clavicle AllmanⅠdisplaced fracture. It not only has the advantages of less trauma and fewer complications of the MIPPO technique, but also can further shorten the operation time and improve the operation maneuverability. It is a better method in the treatment of adult clavicle AllmanⅠdisplaced fracture.

Functional outcomes of distal tibia fractures treated using the minimally invasive percutaneous plate osteosynthesis technique with a locking compression plate

Background: Distal metaphyseal tibia fractures are difficult to treat owing to their limited blood supply, subcutaneous location, and inadequate soft tissue blanket. Minimally invasive percutaneous plate Osteosynthesis (MIPPO) using a locking compression plate (LCP) is a widely used surgical treatment. It is beneficial for the management of distal tibia fractures. This study aimed to assess the functional outcomes of distal tibia fractures treated with the MIPPO technique with an LCP. Methods: The investigators have conducted this prospective study with thirty patients who presented with distal tibia fractures over 8 months. All patients fulfilling the inclusion criteria and exclusion criteria took part in the study. All the patients were surgically managed by the MIPPO technique with LCP under spinal or general anesthesia. The functional and radiological outcomes were evaluated with the American Orthopedic Foot &amp; Ankle Society (AOFAS) scale. Results: A sizable number of the patients were aged 40–60 years, with a mean age of 49.8 years. Most participants were male (66.67%). The mean duration of surgery was 72.60 ± 5.35minutes. The mean length of hospital stay was 7.22 ± 1.45 days.

Preoperative position and protection of radial nerve by B-ultrasound combined with MIPPO for treatment of middle-inferior humerus fractures

Background and purposeOpen reduction and internal fixation through the posterior approach are standard methods for treating middle-inferior humerus fractures. Given the limited operative field and difficulty in locating the radial nerve, the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique via the posterior approach to treat middle-inferior humerus fractures has rarely been reported. This study aims to evaluate the clinical effect of the preoperative study of the radial nerve position by B-ultrasound and its intraoperative protection combined with MIPPO in managing middle-inferior humerus fractures.MethodsThe data were studied retrospectively involving 64 participants who had surgery for middle-inferior humerus fractures from the start of 2017 to the end of 2020. Participants were divided into two groups, those treated with the MIPPO technique, including newly developed dual procedures and preoperative position and protection of radial nerve by B-ultrasound (group A), and those treated with open reduction and internal plating fixation (group B).ResultsAll the cases were followed up for 12–34 months (an average of 25.6 ± 8.76 months), and there was no significant difference in the mean operative duration, surgical incision infection, range of motion (ROM) and MEPS (Mayo elbow performance score) for groups A and B. However, the occurrence of complications (radial nerve palsy, bone nonunion and flexible internal fixation or ruptures) in group B was significantly higher than the group A. A statistically significant difference was observed in the intraoperative blood loss, hospital stay and fracture nonunion time between the two groups. All the cases gained bone union within the MIPPO group.ConclusionMIPPO via the posterior dual approach associated with preoperative position and protection of radial nerve by B-ultrasound does not increase radial nerve injury, however, it exhibits obvious advantages in the bone union, which is worthy of clinical application.

Fixation of anterior pelvic ring fracture with long reconstruction plate combined with MIPPO technique

To evaluate the efficacy of long reconstruction plate combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) technique in the treatment of unstable pelvic anterior ring fractures. From January 2013 to February 2019, 16 patients with unstable pelvic fracture were treated, including 12 males and 4 females, aged from 20 to 60 years(mean 46.5 years). According to Tile classification, there were 4 cases of type B1, 6 cases of type B2, 4 cases of type C1 and 2 cases of type C2. The fracture of all patients was closed, and the time from injury to operation was 7 to 10 days with an average of 6.2 days. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, complications and limb function during the final follow-up were evaluated in 16 patients. All 16 patients were followed up for 12 to 23 months (mean 19.1 months). The operation time was 60 to 180 min (mean 107.8 min). The intraoperative blood loss was 120 to 600 ml (mean 368.1 ml). The fracture healing time was 12 to 20 weeks (mean 16.3 weeks). According to Matta criteria, the fracture reduction was excellent in 6 cases, good in 8 cases and fair in 2 cases. One patient suffered from lateral femoral cutaneous nerve injury during the operation, and the lateral thigh sensation decreased after operation, which recovered after 6 months. One patient had pain stimulated by internal fixation at the iliac fossa. The symptoms were improved after the internal fixation was removed. The fractures of 16 patients were healed satisfactorily and there was no internal fixation loosening. Majeed score at the final follow-up was 67 to 95, excellent in 10 cases, good in 4 cases and fair in 2 cases. Closed reduction and fixation of pelvic anterior ring fracture with long reconstruction plate combined with MIPPO technique through anterior approach has the advantages of less injury, less bleeding time during operation, saving operation time, high intraoperative safety, high fracture healing rate, early functional exercise after operation, and effective treatment of pelvic anterior ring fracture.

A COMPARATIVE STUDY OF MIPPO AND MDLIN APPLIED TO THE TREATMENT OF DISTAL TIBIAL FRACTURES

Objective: This study aims to analyze the clinical treatment effects of the minimally invasive percutaneous plate osteosynthesis (MIPPO) and multi-directional locking intramedullary nail (MDLIN) techniques in patients with distal tibial fractures. Methods: A total of 124 patients with distal tibial fractures, admitted to the People’s Hospital of Zhongjiang County from February 2019 to January 2020, were selected as the research subjects. They were randomly divided into groups ([Formula: see text]). The control group received MIPPO treatment, the observation group received MDLIN treatment, and the postoperative therapeutic effects and complications in the two groups were compared. Results: The patients in the observation group had shorter operative time and lower intraoperative blood loss than those in the control group ([Formula: see text]). The two groups had no significant differences in fracture healing time, complete weight bearing time, or functional recovery. The postoperative complication rate in the cases of the observation group was significantly lower than that of the control group ([Formula: see text]). Conclusion: Both techniques can achieve sufficient therapeutic effects; however, the MDLIN technique has certain advantages, including significantly fewer complications, lower intraoperative blood loss, and shorter operative durations compared to the MIPPO technique.

Functional and Radiological Outcome in the Management of Diaphyseal Humeral Shaft Fracture Using the Minimally Invasive Percutaneous Plate Osteosynthesis (MIPO) Technique

Introduction: Minimally invasive percutaneous plate osteosynthesis (MIPO) is gaining preference nowadays compared to other treatment modalities for diaphyseal fracture of the humerus. We have evaluated the functional and radiological outcome of diaphyseal humeral shaft fracture with the MIPO technique.&#x0D; Methods: A hospital-based prospective study was conducted on 23 adult patients with diaphyseal fracture of the humerus and treated with the Minimally Invasive Percutaneous Plate Osteosynthesis (MIPO) technique. In all cases, 4.5mm locking compression plates were applied. Clinical and radiological evaluation was done at 6 weeks, 3 months, and 6 months.&#x0D; Results: Out of 23 patients, the mean age of patients was 40.3 years. The maximum number of cases were caused due to road traffic accidents 14 (60.9%). The left side was commonly affected with a maximum number of them being Type A fracture 13 (56%) as per AO/OTA classification. The mean operative time was 106 minutes and fracture union was achieved in all patients by the end of 20 weeks (mean 14.83 weeks). In the study group, 1 patient had superficial infection with no evidence of iatrogenic radial nerve injury or implant failure. Shoulder and elbow ROM was restored to normal range.&#x0D; Conclusion: MIPO is a safe and effective technique for the management of diaphyseal humerus fractures, with early fracture healing, less risk of complications such as superficial or deep infection, implant failure, and iatrogenic radial nerve injury, along with a cosmetically acceptable scar.

Comparative study between intramedullary interlocking nailing and minimally invasive percutaneous plate osteosynthesis for distal tibia extra-articular fractures

&lt;p class="abstract"&gt;&lt;strong&gt;Background: &lt;/strong&gt;Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage. There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and intramedullary interlocking (IMIL) nailing for extra-articular distal tibia fractures. The aim of our study is to compare the functional outcome between the two treatment methods.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; This was the prospective comparative study of 50 patients with distal third tibia fractures divided into two groups. First group of patients were treated with MIPPO technique while second group of patients were managed by IMIL nailing. Patients were followed up in outpatient department to assess the functional outcomes, malunion, delayed union, non-union, superficial and deep infection between the two groups.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results: &lt;/strong&gt;Average time taken by patients for full weight bearing in group A was 17.6 weeks as compared to 16.7 weeks in group B. All patients were able to bear weight prior to complete union of fracture. By the process of weight bearing, we believed that it would promote secondary bone healing. On taking X-rays during follow up of included patients starting of radiological union was observed carefully by looking for bridging callus, haziness of fracture line. Appearance of callus was taken average time of 12.5 weeks in group A and 12.1 weeks in group B.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue, bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing. Considering the results of the study, we have slightly more preference for the MIPPO technique.&lt;/p&gt;

Comparative study between intramedullary interlocking nailing and minimally invasive percutaneous plate osteosynthesis for distal tibia extra-articular fractures

PurposeTreatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage. There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and intramedullary interlocking (IMIL) nailing for extra-articular distal tibia fractures. The aim of our study is to compare the functional outcome between the two treatment methods. MethodsThis was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups. The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing. Patients were followed up in outpatient department to assess the functional outcomes, malunion, delayed union, nonunion, superficial and deep infection between the two groups. Statistical analyses were performed using the SPSS software (version 16.0). ResultsAverage malunion (degrees) in the MIPPO group was 5 (3–7) ± 1.41 vs. 10.22 (8–14) ± 2.04 in the IMIL group (p = 0.001). Similarly postoperative knee pain in the IMIL group was 10% vs. 2% in the MIPPO group (p = 0.001). In terms of superficial infection and nonunion, the results were 8% vs. 4% and 2% vs. 6% for the MIPPO and IMIL group, respectively (p = 0.001). ConclusionBoth procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue, bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing. Considering the results of the study, we have slightly more preference for the MIPPO technique.

A prospective study of distal tibial fracture fixation with anatomical osteosyntheses using minimally invasive percutaneous plate osteosynthesis technique

Introduction: Our objective was to evaluate clinical results and functional outcomes of extraarticular distal tibia fracture treated using anatomical osteosyntheses by minimally invasive percutaneous plate osteosynthesis (MIPPO) technique. Materials and Methods: 30 patients of closed distal tibial extraarticular fractures operated by MIPPO technique from November 2018 to October 2019 with age from 20 to 60 years with or without fibula fracture upto 5 cm proximal to distal tibiofibular syndesmotic joint were included in the study. Clinical and radiological assessment for fracture union were performed at 3 weeks,12 weeks and 24 weeks interval and results were analysed by using AOFAS Ankle-Hind foot scale. Results: Thirty patients were followed for 6 months with mean fracture healing time was 16 weeks (12-60 weeks). 14 patients had excellent results with AOFAS score with two patients (6.7%) had delayed union and one patient (3.3%) developed superficial infection but fractures united completely. Conclusion: Minimally invasive percutaneous plate osteosynthesis technique is an effective method of treatment for distal tibial fractures, it provides good, stable fixation with minimal complications.

A comparative study of locking plate by minimally invasive percutaneous plate osteosynthesis versus closed interlocking intramedullary nail in extra-articular distal tibia fractures

&lt;p&gt;&lt;strong&gt;Background&lt;/strong&gt;: To compare functional outcome between minimally invasive percutaneous plate osteosynthesis (MIPO) and intramedullary interlocking nail (IMIL) in the distal one-third extra-articular tibia fracture.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods&lt;/strong&gt;: We retrospectively analysed 32 patients with closed distal tibia extra-articular fractures who underwent IMIL nail and locking plate MIPO technique in 16 patients each. All patients were followed for at least one year with assessment of clinico-radiological union and functional outcome scoring.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results&lt;/strong&gt;: There was comparable functional outcomes, time to union and surgical time both in IMIL nail and MIPO fixation of closed distal extra-articular tibia fractures with similar complication rate. &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions&lt;/strong&gt;: Our study suggests that both IMIL nail and MIPO fixation could be used for closed distal extra-articular tibia fractures as per surgeon’s preference. However, due to small sample size in our study, we cannot draw any definitive conclusions from our preliminary results but consider them as valuable basis for future studies.&lt;/p&gt;

Surgical outcome of tibial condyle fracture with MIPPO technique

Background: Tibial condylar fractures are very common in road traffic accidents; however, sports injury, fall and other trivial trauma can frequently produce these fractures. These are unstable fractures and quite challenging to manage. This study was undertaken to evaluate locking compression plate (LCP) fixation in proximal intra articular tibia fractures by MIPPO (minimally invasive percutaneous plate osteosynthesis) technique. Materials and Methods: The study was conducted from 0ctober 2016 to 2018. 20 cases who had sustained tibial plateau fractures (Schatzker type 1- VI) and operated with LCP fixation using MIPPO technique were included in this study after obtaining informed consent. Follow-up was done at 6 weeks, 12 weeks, 18 weeks and 24 weeks after the surgery and they were evaluated in accordance with modified Rasmussen knee scoring system. Results: Modified Rasmussen functional knee scoring system and modified Rasmussen criteria for radiological assessment was used to analyse the functional outcome among the cases. After evaluation it was observed that 90% of the patients had good to excellent performance. Conclusion: MIPPO technique enables soft tissue stripping via a small surgical incision and provides a rigid fracture reduction. There is also a reduced chance of post traumatic soft tissue injury. Proximal Tibial locking plate is a good device to stabilize the fractures of Tibial plateau (intra articular), especially when used in conjunction with meticulous intraoperative handling of the soft tissues and active participation of the patients in the rehabilitation programme is ensured.

Data were analysed by using SPSS v. 21. Results: As per sample size calculation, 57 patients were included with a mean age of 37.19 ± 9.22 years. There were 45 (78.94%) male patients and 12 (21.05%) female patients. According to AO classification; the most common type was 43A1 with 31 patients (54.38%) whereas 18 (31.57%) were in Type 43A2 and 8 (14.03%) in Type 43A3. In our study, fracture union was achieved in a mean duration of 19.6 ± 3.45 weeks. When the functional outcome was analyzed, 41 (71.92%) patients had excellent outcome, 8 (14.03%) had good results, 5 (8.77%) had fair and 3 (5.26%) had poor outcome based on the subjective result and 44 (77.19%) patients had excellent, 7 (12.28%) had good, 3 (5.26%) had fair and 3 (5.26%) had poor result based on an objective result of Ovadia-Beals clinical scoring system. Conclusion: Thus MIPPO can be highly successful in achieving good to excellent outcomes in the maximum number of patients presented with a distal tibia fracture. So in the future, we can rely on this technique for such types of fractures.&#x0D;

Minimally invasive percutaneous plate osteosynthesis for treatment of proximal humeral shaft fractures.

The objective of this study was to evaluate the feasibility and safety of a minimally invasive percutaneous plate osteosynthesis (MIPPO) procedure for proximal humeral shaft fractures using lateral minimal proximal and distal approaches and lateral bridge plating with primary radial nerve control, and to assess its clinical and radiographic outcomes. A retrospective review was done for the medical records of adult patients admitted for fracture of the proximal humeral shaft without associated injury to the ipsilateral upper limb and who consented to undergo a novel MIPPO technique herein reported. Patients were reviewed at regular follow-up periods and assessed at a final follow-up for evaluation of Constant, normalized Constant, and QuickDASH scores. There were 21 adult patients with mean age of 56years. Three patients were lost from early follow-up; one of them had post-operative radial nerve paralysis. Eighteen patients were reviewed for the purpose of this study at a mean of 20months of final follow-up; among them, one patient developed post-operative radial nerve paralysis with complete recovery after three months. Bone healing was achieved without any malalignment in 17 patients at a mean of 15weeks, and one patient developed nonunion. At final assessment (mean, 20months), the mean values of Constant, normalized Constant, and QuickDASH scores were 84 (range, 59 to 100), 95 (range, 73 to 100), and 5 (range, 0 to 18.2) respectively. Compared to pre-reported methods of MIPPO, this technique of lateral proximal and distal mini-approaches with lateral bridge plating after primary control of the radial nerve seems safe and feasible for proximal humeral shaft fractures. It gives good clinical and radiographic results with excellent restoration of upper limb function, very low incidence of post-operative radial nerve injury, and high rate of bone union in good alignment.
