RESUMO
Objective:To compare minimally invasive percutaneous plate osteosynthesis (MIPPO) and open reduction and internal fixation via traditional lateral L-type approach (ORIF-LA) in the therapeutic effects concerning reduction and calcaneal alignment for Sanders Ⅲ/Ⅳ calcaneal fractures.Methods:A retrospective analysis was conducted of the 105 patients with calcaneal fracture who had been treated at Department of Foot and Ankle Surgery, Qilu Hospital from 2014.1 to 2018.2. Of them, 50 were treated with MIPPO (group A) and the other 55 with ORIF-LA (group B). The X-ray lateral and axial films, three-dimensional computed tomography (CT) of the calcaneal were taken pre-operatively and post-operatively to evaluate the reduction and calcaneal alignment. The American Orthopedic Foot Ankle (AOFAS) Ankle-Hind Foot Scale and Foot Function Index-Verbal Rating Scales (FFI-5pt) were adopted to assess the therapeutic effects. The postoperative complications of the two groups were compared.Results:All patients were followed up for 20-36 months (mean 24 months). The length of hospital stay and incision in group A was shorter than that in group B ( t=-11.276, -25.965, P<0.001). In group A and group B, the correction degrees of B?hler angle and Gissane angle were (34.49±3.81)°, (35.12±3.77)° and (-20.62±9.86)°, (-20.94±8.38)°, respectively ( P>0.05). Posterior calcaneal articular surface defects or steps in group A and group B were 1.55(1.12, 2.00)mm and 1.20(1.03, 1.60)mm, indicating that there was no significant difference in the reconstruction ability between the two groups ( P>0.05). There was no significant difference in VAS pain score between the two groups at 3 months after operation ( P>0.05), but group A was significantly lower than group B at 3 days after operation ( P<0.001). There was no significant difference in AOFAS and FFI-5pt scores between the two groups at 18 months after operation ( P>0.05). The complications of group A (6.0% incision infection, 2.0% incision area sensory disturbance, 2.0% foot stiffness) were lower than those of group B (16.36% incision infection, 14.55% incision area sensory disturbance, 10.9% foot stiffness) ( P<0.05). Conclusions:Compared with ORIF-LA, the MIPPO shows promising results in terms of reduction capacity and safety. Use of the MIPPO technique minimized the risk of postoperative wound complications and achieved superior functional outcomes compared with standard locking plate fixation via the extended lateral approach. MIPPO can be used as a choice for the treatment of calcaneal fracture.

RESUMO
Objective: To compare the effectiveness of proximal femoral nail anti-rotation (PFNA) combined with minimally invasive percutaneous plate osteosynthesis (MIPPO) and Intertan intramedullary nail fixation by closed reduction in the treatment of AO/Orthopaedic Trauma Association (AO/OTA) type 31-A3.3 intertrochanteric fracture with incomplete lateral wall. Methods: The clinical data of 54 patients with AO/OTA type 31-A3.3 intertrochanteric fracture who met the selection criteria and were admitted between January 2012 and January 2018 were retrospectively analyzed. According to different surgical methods, the patients were divided into group A (24 cases with lateral wall reconstruction by MIPPO combined with PFNA internal fixation) and group B (30 cases with Intertan intramedullary nail fixation by closed reduction only). There was no significant difference between the two groups ( P>0.05) in terms of gender, age, side of injury, cause of injury, and combined medical diseases. The operation time, intraoperative blood loss, time to weight-bearing, fracture healing time, and postoperative complications were recorded and compared between the two groups. The tip apex distance (TAD) was measured at 2 days, 2 months, and 1 year after operation. At 12 months after operation, the hip joint function was evaluated according to Harris scoring standard, and the rate of conformity (Harris score were more than 70) was calculated. Results: The wounds of the two groups healed by first intention, without infection, skin deformity, and other incision complications. The operation time and intraoperative blood loss of group A were significantly more than those of group B, and the time to weight-bearing and fracture healing were significantly shorter than those of group B ( P0.05). There was 1 case of infection, 1 case of screw withdrawal, 2 cases of screw removal, and 1 case of bone nonunion in group B, the incidence of complications was 16.7%; there was only 1 case of screw withdrawal combined with screw blade withdrawal in group A, the incidence of complications was 4.2%; there was no significant difference between the two groups ( χ2=2.109, P=0.146). At 12 months after operation, the Harris scores of pain, function, malunion, range of motion, and total score in group A were significantly better than those in group B ( P<0.05). The rate of conformity of group A was 95.83% (23/24) and 76.67% (23/30) in group B, and the difference between the two groups was significant ( χ2=3.881, P=0.049). Conclusion: For the AO/OTA type 31-A3.3 intertrochanteric fracture with incomplete lateral wall, compared with the closed reduction Intertan intramedullary nail fixation, the incidence of internal fixation failure after MIPPO reconstruction with lateral wall combined with PFNA fixation was lower, the time to weight-bearing was earlier, and the postoperative function was better.
RESUMO
PURPOSE: This study analyzed the results of the midclavicle fracture treatment using the minimally invasive percutaneous plate osteosynthesis (MIPO) technique in a retrospective manner. MATERIALS AND METHODS: Between March 2013 and March 2017, this study analyzed 40 patients who received MIPO surgery. Excluding 1 patient who underwent surgery on another body part injury, and 4 patients who were lost to follow-up over 1 year, 40 patients were analyzed for their operation time, bone union, functional American Shoulder and Elbow Surgeons score, scar lengths, pain relief (visual analogue scale), and complications. RESULTS: All patients over a 1 year of follow-up achieved bone union, and American Shoulder and Elbow Surgeons score 97.6 (94–100) on their shoulder functional scores. Their average operation time was 42.7 minutes, and the average scar length was 6.1 cm. Eighteen patients successfully received metal removal using the previous scar without additional incision. The clavicle length was similar in the normal and operated group. CONCLUSION: Despite its small sample size, clavicle fixation using the MIPO technique can be considered an effective treatment because of its limited number of complications, such as nonunion and rotational angulations.

PURPOSE: To retrospectively compare minimally invasive percutaneous plate osteosynthesis (MIPPO) with open plate fixation for the treatment of clavicle midshaft fracture. MATERIALS AND METHODS: Between November 2011 to May 2014, 40 cases that were followed for more than 1 year–among all cases of MIPPO and open plate fixation–were analyzed. The study population was divided into two groups: group A included 20 cases of MIPPO and group B included 20 open plate fixation cases. The comparative analysis between the two groups was based on the operative time, bone union, functional evaluation (American Shoulder and Elbow Society score), incision length, pain relief (visual analogue scale, VAS), and complication. RESULTS: The bone union was successful for all the cases, and the functional evaluation scores of the shoulder joint were satisfactory for both groups (p>0.05). The operative time was 47.5 minutes and 58.7 minutes for group A and B, respectively (p<0.05). The incision length for group A was 6.2 cm and that for group B was 10.7 cm with statistical significance (p<0.05). Pain relief (VAS) after surgery for group A showed a quick recuperation in the early stages. For complications, there were 2 cases of dysesthesia and 1 case of malunion due to metal fixation failure in group A. There were 6 cases of dysesthesia and 2 cases of cosmetic problem due to hypertrophic scar in group B. CONCLUSION: Surgical results of clavicle shaft fracture were satisfactory for both groups, but group A had advantages of shorter operative time, minimal incision length, and better pain relief in the early stages compared with group B. However, we need further evaluations with long-term follow-up results and complications, such as malunion and exposure on radiation.

RESUMO
PURPOSE: This goal of this study is to evaluate the clinical and radiological outcomes of proximal tibial comminuted fractures treated with medial minimally invasive percutaneous plate osteosynthesis (MIPPO). MATERIALS AND METHODS: We evaluated 43 patients who underwent medial MIPPO from February 2008 to February 2012 and were followed up for more than one year. According to the AO/OTA classification, there were 30 patients of 41-A3 and 13 patients of 41-C2. Thirty-six patients had closed fractures and seven patients had open fractures. We assessed clinical outcomes, radiologic results and postoperative complications. RESULTS: All fractures were united at an average of 18.3+/-8.1 weeks except three patients with nonunion. According to Schatzker and Lambert assessment, excellent results were achieved for 22 patients and good results were achieved for 21 patients. The average tibial plateau angle was 89.1degrees+/-2.7degrees and the average posterior tibial slope angle was 10.5degrees+/-4.6degrees. In assessment of lower limb alignment, the average femorotibial angle was 175.1degrees+/-2.9degrees and the mean deviation of mechanical axis was 46.5%+/-12.7%. In terms of complications, three patients had nonunion, but complete bony union was achieved by autogenous cancellous bone grafting. Seven patients complained of skin irritation around the plate. However, there was no skin necrosis, infection, or limited range of motion in seven patients with skin irritation. CONCLUSION: Medial MIPPO for proximal tibial comminuted fractures provides favorable clinical outcomes and good radiological alignments.

PURPOSE: To evaluate the efficacy of surgical treatment through retrospective comparison of minimally invasive percutaneous plate osteosynthesis (MIPPO) vs open plate fixation in the treatment of the distal femur fractures. MATERIALS AND METHODS: Thirty-one patients with distal femur fractures from January 2002 to December 2010 were divided into two groups depending on the surgical method. Minimum follow up was 12 months. Group A consisted of 17 patients treated with MIPPO, and group B was comprised of 14 patients treated with open plate fixation. Clinical outcomes including operation time, transfusion rate, rehabilitation, range of motion, and interval change of postoperative C-reactive protein (CRP) were evaluated to assess postoperative inflammatory reaction, postoperative complications and clinical results with the use of Sanders criteria. RESULTS: The operative time was 86/135 min and transfusion volume was 0.8/1.9 unit respectively. The postoperative 3-day and 7-day CRP were 7.4/1.5 mg% in group A and 10.3/2.4 mg% in group B, showing more minimal tissue injury and early recovery in group A. There were no significant differences in clinical results by Sanders criteria in both groups. CONCLUSION: Both MIPPO and open plate fixation for the treatment of distal femur fractures showed comparably good results. However, the MIPPO technique is superior to group B in view of minimal tissue injury and operation time and was proven to lessen the transfusion rate.

PURPOSE: To evaluate the clinical results of minimally invasive percutaneous plate osteosynthesis using a periarticular plate (Zimmer, Warsaw, IN, USA) for distal tibia fractures. MATERIALS AND METHODS: 27 patients with distal tibia fractures were treated operatively by minimally invasive percutaneous plate osteosynthesis. The patients were followed for at least 1 year. The duration for bone union, complications after the surgery, the amount of skin irritation at the site of plate insertion was evaluated using the VAS score and the Olerud and Molander ankle score. The average age of the patients was 56 years old (range, 30~81 years) with an average follow up period of 21 months (range, 12~30 months). RESULTS: The average time from trauma to surgery was 6 days (range, 2~19 days). 10 cases showed an associated distal fibular fracture. The average time for bone fusion was 14 weeks (range, 8~40 weeks) with 1 case of angular deformity with more than 5 degrees. The amount of skin irritation due to the periarticular plate resulted in a VAS score of 2.2 points. Evaluation of the ankle function test showed an average of 90.2 points, resulting in satisfactory. CONCLUSION: The periarticular plate used in minimally invasive percutaneous plate osteosynthesis for distal tibia fractures was concluded to give a firm fixation of the fracture site as bony fusion could be acquired without any callus formation, and few skin irritation due to plate has seem to be an advantage.

Objective To explore efficacy of minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of distal tibia comminuted fracture by using normal anatomical plate. Methods Between January 2007 and July 2008,18 cases of distal tibia facture were treated by MIPPO using anatomical plate. The clinical data of the patients were reviewed. Results A mean of 6.5 cm incision (5.0-8.5 cm) was made in the patients; the intraoperative blood loss ranged from 60 to 300 ml (mean,145 ml);and the operation time ranged from 30 to 120 min with a mean of 63 min. After the surgery,2 patients developed mild skin necrosis,and was then cured by conventional therapy; no patient had nonunion of the fracture,failure of internal fixation,or delayed wound healing. The 18 cases were followed up for a mean of 8 months (range,4 to 10 months); all of them were healed clinically and could walk without crutch in 4 months postoperatively. According to Johner-Wruhs score system,11 were excellent and 7 were good; the excellent-good rate was 100%. Conclusions MIPPO with anatomical plate is an optimal treatment for distal tibia comminuted fracture with advantages in protecting the soft issues and bony blood supply,promoting the wound-healing process,and reducing the rate of complications.
RESUMO
Objective To evaluate the short-term outcomes of minimally invasive percutaneous plate osteosynthesis(MIPPO) combined with locking compression plate(LCP) in the treatment of distal tibial fractures.Methods From June 2004 to March 2006,16 patients with distal tibial fractures were treated using MIPPO combined with LCP in our department.According to the AO classification,there were 7 cases of type 43A1,5 type 43A3,2 type 43B1 and 2 type 43C3.After reduction of tibial fracture with three methods,LCP was inserted and fixed with locking screw.All the cases were followed up periodically after the operation.Results All the cases were followed up for 5 to 20 months(mean,11.5 months).Primary wound healing was achieved in 16 patients.No complications,such as non-union,abnormal union and breakage of the plate,occurred in the cases.Callus formation was seen on X-rays at 7.6 weeks(4 to 12 weeks) after the surgery,when the patients began part weight-bearing exercises.The bone union was detected at 16 weeks(8 to 20 weeks),when the patients began full weight bearing.3 patients felt uncomfortable at the distal tibia around the implant.According to the AOFAS Ankle-Hindfoot Scale,14 cases(87.5%) were excellent and 2(12.5%) were good.Conclusions MIPPO combined with LCP technique is an effective treatment for the fractures of the distal tibia.This minimally invasive method can achieve stable fixation,promote bone healing,and permit early functional rehabilitation.
RESUMO
The importance of the biology and the care for the soft tissues and bone during internal fixation of the fracture, as the fourth AO principle, had been stressed. A conventional AO compression plate pressed against the bone surface interferes with the cortical blood flow and induces structural changes underneath the plate. Low contact dynamic contact plate(LC- DCP) could reduce the area of contact between plate and bone undercuts. Locking head screws, the Point Contact Fixator (PC Fix), and the Less Invasive Stabilisation System (LISS) had the next evolution.The so- called internal fixator can be considered as an external fixator, which has been approximated very close to the bone, however, without actually touching or compressing bone. This feature prevents any additional damage to bone vascularity. The stability of the internal fixator depends on the angular stability of the screw- plate combination. The new LISS and Locking Compression Plate( LCP) offer new options and challenges in modern operative fracture care. These implants are ideal for the MIPO (minimally invasive (percutaneous) plate osteosynthesis) and appear to have a considerably better purchase in osteoporotic bone. Nevertheless, it must be stated that these new plates and screws do not solve all problems, either as they too demand a very careful planning of every procedure, which includes a re- thinking of the classical AO principles, especially when addressing meta- and diaphyseal fractures.
