Outcome of Pertrochanteric Femur Fractures with Proximal Femur Locking Compression Plate

Background: Fractures of the proximal femur, including fractures affecting the pertrochanteric region, have become a public health problem. Owing to aging of the population, we have to operate on even more elderly patients who sometimes present with significant co-morbidities. Although conventional implants have given good results in stable peritrochanteric fractures, proximal femur locking compression plate (PFLCP) which has been recently introduced is better suited for comminuted, unstable pertrochanteric fractures and osteoporotic bones. In PF-LCP, bone-implantconstruct so formed is mechanically stable and fixation failure due to screw loosening in osteoporotic bone can be reduced. Materials &Methods: This prospective study was conducted in our institute and was approved by local ethical committee. Twenty-five consecutive patients of either sex with age more than 60 years (range, 60-84) having pertrochanteric fractures were operated upon with PFLCP. A.O classification was followed in the study and Singh抯 index for osteoporosis was calculated. Operating time, blood loss and any technical difficulty with the implant were recorded. Patients were followed clinically and radiologically for union at fracture site and implant-related complications for a period of 24 months. The Harris Hip Score was used to document hip functions at final follow-up. Observations: Amongst the 25 patients, the average operation time in our study was 66.60�.57 minutes. The average radiological union was 3.40�63 months (13.6 weeks). Average time for full weight bearing was 13.12�90 weeks. There were two cases of wound infection, one case of coxa vara and one case of a proximal screw back-out. There was no case of plate lift or screw breakage. There was no case of non-union. Conclusion: The PFLCP can be a feasible alternative to the treatment of peritrochanteric fractures. Treatment with PFLCP can provide good-to-excellent healing in osteoporotic bones having comminuted and unstable peritrochanteric fractures, with a limited occurrence of complications.

A COMPARATIVE STUDY ON FUNCTIONAL OUTCOME OF SUPRACONDYLAR FEMUR FRACTURE MANAGED BY OPEN REDUCTION VS MIPPO.

Background: Distal femur fractures are complex injuries producing long term disability and present considerable challenges in management. These fractures poses challenges to the treating surgeon because of thin cortex of the femoral condyles, wide medullary canal, relative osteopenia, short condylar fragment and comminution involving articular surface. Distal femur fracture disrupts normal knee joint functioning, hence needed anatomical reduction and stable internal fixation to prevent crippling disabilities and hardware failure Objectives: This study aimed to Compare Functional outcome of supracondylar fracture femur managed by Open reduction VS MIPPO Material & Methods: In this study 30 patients with fracture of distal femur were studied. The method used for fracture fixation was both closed and open reduction with internal fixation with locking compression plate. Patients were selected based on inclusion and exclusion criteria and were followed up ranged from 3 months to 1 year. The results were analysed with NEER'S score. Results: In our study of 30 lower end of femur fractures, 5 was Muller's Type A1; 5 were of Muller's Type A2.; 4 were of Muller's Type A3;2 were B;3 was of Muller's Type C1 ; 9 were of Muller's Type C2; and remaining 2 were Muller's Type C3. Mean age of the patients was 48.4 years with age ranging from 18-70 years with more than two thirds of them being male. Right sided fractures were predominant. RTA being the cause of injury for most of them but there are also cases of fall in the older age group >50 years. MIPPO surgery was done in less time when compared to open reduction.2/3rd of cases done by MIPPO are done in less than 90 minutes when compared to open reduction where the average duration of times was between 90 to 120 minutes accounting 60% of patients. There is not even a single case done by MIPPO with duration of more than 120 minutes. Early radiological union less than 16-18 weeks was seen in most cases of MIPPO technique when compared to OPEN reduction. Open reduction accounted nearly 20% of cases with infections while MIPPO accounted only 6.67% infections mostly of superficial type. There is single implant failure seen in our study that too with MIPPO technique which underwent revision surgery. Better functional outcome was seen in MIPPO procedure accounted 73.33% when compared to open procedure of 66.67%.Poor functional outcome was seen in 13.3% of patients who underwent open reduction and 6.67% cases who underwent MIPPO procedure. Functional outcome was based on NEER's scoring system. Conclusion: Locking compression plate is an important armamentarium in treatment of fractures around knee especially when fracture is severely communited and in situations of osteoporosis. Overall MIPPO has better functional outcome than OPEN reduction especially in extraarticular fractures with comminution as there will be early radiological union,less soft tissue damage,least infection rate which ultimately helps in early physiotherapy and early weight bearing resulting in best functional outcome.

Biomechanical Comparison of Novel and Traditional LCP Fixation for Femoral Shaft Fractures / 医用生物力学

Objective To compare biomechanical properties of the traditional and novel locking compression plate （LCP） for treating femoral shaft fracture, so as to provide theoretical basis for selecting more effective bone plate. Methods The bending strength and fatigue tests on the plate were performed, and the finite element analysis on deformation, stress and life of the plate were conducted by using ANSYS Workbench. Results The average bending yield load and bending strength of the novel LCP were 1.4 times of that of the traditional LCP, and the average cycle times of the novel and traditional LCP were 106 and 47 091, respectively. The difference of service life for two LCPs was 33.8%. ConclusionsThe failure probability of the novel LCP is smaller than that of the traditional LCP, and the novel LCP has more effective biomechanical stability.

Comparative Study Regarding Functional and Radiological Outcomes of Different Modes of Fixation for Distal Femur Fracture.

Treatment of distal femur fractures has recently evolved towards indirect reduction and minimally invasive techniques. The goal is to strike a balance between the mechanical stability of the fragments and the biological viability. Advent of MIPO technique has reduced the amount of soft tissue injury, delayed healing, tissue necrosis and infections. The objective was to compare the functional and radiological outcome of fracture distal femur treated by open reduction with LCP by minimally invasive plate osteosynthesis (MIPO). We wanted to compare the clinical and radiological differences between open and MIPO techniques for distal femoral fracture fixation.METHODSThis was a prospective interventional study. 41 subjects with closed supracondylar femur fracture treated surgically from March 2013 to December 2017, were evaluated prospectively for functional and radiological outcome results after fixation with distal femoral locking compression plate in open or minimally invasive way, with minimum follow up of 1 year. IBM SPSS Ver. 25 software was used to perform statistical analysis.RESULTSThe mean age of 41 treated patients was 53.8 ± 13.7 years and ranged from 23 to 84 years. 19 patients were females and 22 were males. Mean time to surgery was 5.7 ± 2.9 days with minimum 2 and maximum of 18 days from injury. Initially 20 patients underwent open surgery and 21 patients were operated by minimally invasive plating technique. In all cases, a 316L stainless steel alloy distal femoral locking plate was used.CONCLUSIONSKnee ROM could be started at a mean of 1.4 weeks earlier in the MIPO group and this was statistically significant. The two groups did not differ significantly in start of full weight bearing. Knee flexion at 6 weeks was also comparable in the two groups. However, knee flexion was average 21.9° higher in MIPO group at 1 year which was significantly different than ORIF group. The proportion of patients with >90° and >110° knee flexion also varied significantly between the groups. VAS score in MIPO group was significantly less at 6 weeks but difference was non-significant at 1 year. There were 2 cases with non-union and implant failure in the ORIF group, but the proportion was not significant. There was 10° FFD in 1 patient of ORIF group, while varus deformity occurred in 3 patients of MIPO group. The proportion of deformity was not significantly different between the two groups.

INTRODUCCIÓN: El objetivo de este trabajo fue determinar los resultados luego de una reconstrucción de doble banda del LCP (RLCP DB). MATERIALES Y MÉTODOS: Se incluyeron todos los pacientes sometidos a una RLCP DB artroscópica primaria para las lesiones completas de LCP (Grado III), entre mayo de 2010 y marzo de 2015. Se realizaron valoraciones funcionales (Tegner, Lysholm, WOMAC, SF-12) y objetivas (radiografías de estrés tibial posterior) antes y a un mínimo de dos años después de la operación. RESULTADOS: Cien pacientes que se sometieron a RLCP DB se incluyeron en este estudio. El promedio de seguimiento para la cohorte de RLCP DB fue de 2.9 años (rango, 2- 6 años). Hubo una mejoría significativa de todos los parámetros funcionales (todos los valores p <0,001). La diferencia media de lado a lado (DLL) en la traslación tibial posterior en radiografías de estrés mejoró de 11,0 ± 3,5 mm antes de la cirugía a 1,6 ± 2,0 mm después de la operación (p <0,001). CONCLUSIÓN: Se observaron resultados funcionales y objetivos significativamente mejores después de una RLCP DB en un seguimiento promedio de 3 años, con bajas tasas de complicaciones, independientemente de la patología ligamentaria concomitante o el momento de la cirugía (agudo o crónico). Además, se obtuvieron resultados clínicos subjetivos y funcionales similares en comparación con las reconstrucciones aisladas del LCA. Tipo de estudio: Serie de Casos. Nivel de evidencia: II.

BACKGROUND: to report on the outcomes after double-bundle PCL reconstructions in isolated versus combined injuries and acute versus chronic PCL reconstructions. METHODS: All patients who underwent a primary endoscopic RPCL DB for complete PCL tears (Grade III) PCL tears between May 2010 and March 2015 were reviewed. Patient reported outcome scores (Tegner, Lysholm, WOMAC, SF-12) and objective posterior stress radiographs were collected preoperatively and at a minimum two-years postoperatively. RESULTS: One hundred patients who underwent RPCL DB were included in this study. The mean follow-up for the PCL cohort was 2.9 years (range, 2-6 years). All functional scores improved at last follow up (all p values <0.001). The mean side-to-side difference (DLL) in posterior tibial translation on kneeling stress radiographs improved from 11.0 ± 3.5 mm preoperatively to 1.6 ± 2.0 mm postoperatively (p<0.001). CONCLUSION: Significantly, improved functional and objective outcomes were observed after anatomic-based RPCL DB at a mean 3 years follow-up, with low complication rates, regardless of concomitant ligamentous pathology or timing to surgery. Additionally, contrary to previous reports, comparable subjective and functional clinical outcome were achieved compared to an isolated ACL reconstruction control cohort. Type Study: Case report. Level of evidence: II.

Objective To compare the clinical efficacy of single and double locking compressing plates(LCP)treatment for Schatzker type Ⅵ tibial plateau fractures.Methods Patients(n=90)with Schatzker type Ⅵ tibial plateau fractures were randomly divided into two groups according to the treatment methods (single LCP group and double LCP group;45 patients in each group) and analyzed retrospectively.Operative duration,intraoperative bleeding volume,postoperative wound infection,Rasmussen anatomical score and functional score were measured and compared between the two groups.Results More favorable results were achieved in the single LCP group than in the double LCP group in operative duration [(51.4 ± 4.03)h vs.(76.2±5.5)h(t=24.514,P＜0.001)]and intraoperative bleeding volume[(173.7±8.8) ml vs.(212.4 ± 4.9) ml (t =25.911,P ＜ 0.001,respectively)].Further more,three cases of postoperative woundin fection were seen in the double LCP group,while none was observed in the single LCP group.There was no significant difference in the percentage of satisfactory Rasmussenanatomical scores and functional scores between the two groups one year afteroperation(~ =-0.442,P=0.659).Conclusions Compared with double LCP fixation,single LCP fixation is more advantageous for the treatment of Schatzker type Ⅵ tibial plateau fractures.

Total Hip Arthroplasty in Patient with the Sequelae of Legg-Calve-Perthes Disease / 대한고관절학회지

PURPOSE: Patients who have secondary hip osteoarthritis as sequelae of Legg-Calve-Perthes disease (LCPD) are severe deformities of femoral head and acetabulum. A few studies have presented that the clinical results and risks associated with total hip arthroplasty (THA) for patients with a history of LCPD were not satisfactory. In this study, we reported the radiographic and clinical outcomes of THA in patients with sequelae of LCPD. MATERIALS AND METHODS: Between March 2007 and May 2012, 23 hips (23 patients) underwent cementless THA and were followed up at least 2 years after surgery. There were 11 male patients and 12 female patients with an average age of 49.2 years old (range, 25 to 69 years old), and the average follow up period was 40.8 months (range, 24 to 84 months). The clinical and radiological evaluations were performed. RESULTS: The Harris hip score improved from 48.3 points preoperatively to 92.4 points at the time of the last follow-up. The shortening of affected limb was improved from -1.6 cm to 0.2 cm. The complications included one case of sciatic nerve palsy that developed after extensive lengthening of lower extremity, three cases of intraoperative femur fractures. There was no component loosening. CONCLUSION: Fractures and motor nerve palsies may be more frequent in this population. Careful preoperative planning should be performed to overcome the technical pitfalls. If overcoming this early complication, the clinical and radiological evaluations showed excellent outcomes at average 40-month follow-ups.

Objective To investigate the clinical significance of DHS and LCP in treating elderly patients with intertrochanteric fracture.Methods 58 elderly patients were randomly divided into 2 groups.30 of them( DHS group) were treated with DHS,while 28 cases of them were treated with LCP.Blood loss,operation time,bone healing time and Harris score were analyzed.After 1-year follow time,effective rate and complication rate were also recorded and evaluated in the 2 groups.Results The complication rate in LCP group was lower than that in DHS group(P ＜0.05),while the effective rate and Harris score in LCP were higher than that in DHS group( P ＜0.05 ).There were no significant differences in blood loss,operation time and bone healing time between the 2 groups ( P ＞ 0.05 ).Conclusion Compared with DHS,LCP is effective in treating elderly patients with intertrochanteric fracture.

Effects of Multiple Drilling on the Ischemic Capital Femoral Epiphysis of Immature Piglets

PURPOSE: This study investigated the effects of multiple drilling on the immature capital femoral epiphysis following ischemic injury in a piglet model. MATERIALS AND METHODS: Ischemic necrosis of capital femoral epiphysis was induced bilaterally in 12 piglets using a cervical ligation method. Three weeks later, medial, central, and lateral 3 drill holes were made on the left femoral head using 0.062" K-wire. At 3, 6, 9, and 12 weeks following the multiple drilling, femoral heads were harvested from each three piglets. On histologic examination, percent of revascularization, percent of osteoblast surface, capital femoral epiphyseal quotient and proximal femoral growth plate height were evaluated. Untreated right femoral heads served as control. RESULTS: While percent of revascularization of left capital femoral epiphysis with multiple drilling was significantly higher than untreated control side (p<0.001), percent of osteoblast surface, capital femoral epiphyseal quotient and proximal femoral growth plate height showed no significant difference. CONCLUSION: This study indicates that multiple drilling could promote revascularization of ischemic capital femoral epiphysis, and multiple drilling does not appear to produce bony physeal bars at short-term, if using small diameter drill. However, multiple drilling alone does not seem to prevent femoral head deformity or to promote new bone formation.

ConclusionFixation of elderly fracture of proximal humerus with locking compression plate(LCP) by minimally invasive approach from lateral shoulder is a safe, reliable and minimally invasive procedure with good reduction and stable fixation. Early post-operative functional exercise may be permitted for preventing shoulder joint adhesion.

Treatment of Distal Tibia Fracture using MIPPO Technique with Locking Compression Plate: Comparative Study of the Intraarticular Fracture and Extraarticular Fracture / 대한족부족관절학회지

PURPOSE: To evaluate the efficiency of the minimally invasive percutaneous plate osteosynthesis (MIPPO) with locking compression plate (LCP) for distal tibial metaphyseal intra-articular fracture compared with extra-articular fracture. MATERIALS AND METHODS: From February 2006 to June 2008, 21 patients with distal tibia metaphyseal intra-articular fracture and 20 patients with extra-articular fracture were treated operatively by MIPPO technique with LCP and followed for at least one year. In the group with intra-articular fracture, mean age was 48.85 years old and a mean follow-up was 15 months. In the other group with extra-articular fracture, mean age was 52.35 years old and a mean follow-up was 14.5 months. The type of fracture was evaluated using the AO/OTA classification and open-fractures were according to the Gustilo-And gron classification. Radiologic evaluation with fracture healing and tibial alignment, clinical evaluation with Olerud and Molander ankle score and restriction of motion were done for treatment. RESULTS: According to AO/OTA classification, There were 21 type A, 15 type B, 5 type C. Average union time of the intra-articular fracture (type B, C) was 18.7 weeks. Average union time of the extra-articular fracture (type A) was 17.1 weeks. All fractures were healed without malunion. There were no difference of mean restriction angle between intra-articular fracture (ankle dorsiflexion was 3.57 degree, plantar-flexion was 5.95 degree) and extra-articular fracture (ankle dorsiflexion was 3 degree, plantar-flexion was 3.75 degree). There were no difference of Olerud and Molander ankle score between them as a mean score of intra-articular and extra-articular was 89.25, 91.25 each other. As a complication, there were 3 case of skin necrosis, 8 case of discomfortable skin tenting by plate and 1 superficial infection, but could be healed by conservative care. CONCLUSION: MIPPO technique, combined articular reduction, with LCP of distal tibial metaphyseal fracture was a good method with high functional recovery.

The Comparison of LC-DCP versus LCP Fixation in the Plate Augmentation for the Nonunion of Femur Shaft Fractures after Intramedullary Nail Fixation

PURPOSE: The purpose of this study was to evaluate the efficacy of the surgical treatment through the comparison of LC-DCP (Limited Contact-Dynamic Compression Plate) versus LCP (Locking Compression Plate) fixation in the plate augmentation for the nonunion of femur shaft fractures after intramedullary nail fixation. MATERIALS AND METHODS: Twenty-four patients with the nonunion of femur shaft fractures after intramedullary nail fixation who underwent plate augmentation were evaluated from Mar. 2001 to Sept. 2005. The group with LC-DCP augmentation was done bicortical screw fixation and the group with LCP was done monocortical fixation. RESULTS: There was one case of nail breakage in LC-DCP group, but sound bony union were achieved uneventfully in all the cases of both group. LCP fixation was slightly superior to LC-DCP fixation in view of the bony union time, operating time, postoperative Hb down, amount of postoperative transfusion, but there was no statistical difference (p>0.05). CONCLUSION: We got the satisfactory results after monocortical LCP augmentation as well as bicortical LC-DCP fixation and have concluded that monocortical LCP fixation was an effective treatment option for nonunion of femur shaft fracture occurred after Intrmedullary nail fixation.

PURPOSE: To evaluate and compare the outcome between interlocking IM nailing and LCP fixation in the treatment of distal metaphyseal tibial fracture. MATERIALS AND METHODS: From January 2000 to December 2007, 17 patient were treated by interlocking IM nail and 13 patient were treated by LCP fixation for distal metaphyseal tibial fracture. RESULTS: According to AO classification, there were 2 type A1 fracture (12%), 6 type A2 fracture (36%), 3 type A3 fracture (18%), 4 type B1 fracture (24%), 1 type B3 fracture (6%), 1 type C1 fracture (6%) in interlocking IM nailing group and 1 type A2 fracture (7.7%), 2 type A3 fracture (15.4%), 3 type B1 fracture (23%), 3 type B2 fracture (23%), 3 type C1 fracture (23%), 1 type C2 fracture (7.7%) in LCP fixation group. The clinical functional outcome (according to AOFAS score) is 75.6 point in IM nailing group and 81.5 point in LCP fixation group. In IM nailing group, 65% of patient showed satisfactory result and In LCP fixation group, 77% of patient showed satisfactory result. CONCLUSION: There is no difference on clinical results between IM nailing and MIPPO (minimal invasive percutaneous plate osteosynthesis) group in the treatment of distal tibia fracture. But MIPPO group have higher subjective satisfactory score and less complication rate. The weakness of our study is a small case number and limited follow-up and we believe a better designed prospective study will be needed.

3.5 mm T-shaped LCP (Locking Compression Plate) Fixation for Unstable Distal Clavicular Fractures

PURPOSE: To review the clinical and radiological results after an open reduction and internal fixation with a T-shaped LCP for unstable distal clavicle fractures. MATERIALS AND METHODS: From February 2005 to June 2006, ten patients with distal clavicle Neer type II fractures were treated with an open reduction and internal fixation with a T-shaped LCP. Bony union was identified by plain radiography. The clinical results were analyzed according to the UCLA scoring system. RESULTS: The mean time to fracture union was 9weeks and union was achieved in all cases. The mean UCLA score was 33.4 (30-35); excellent in 8 cases and good in 2 cases. In one case, loosening of one distal screw was occured and mild AC joint subluxation was observed in another case. CONCLUSION: 3.5 mm T-shaped LCP fixation is a useful technique for treating unstable distal clavicle fractures. This procedure provide stable fixation with no further AC joint injury.

Comparison of LC-DCP versus LCP for Internal Fixation of Humeral Shaft Fractures in Elderly Patient

PURPOSE: To compare outcomes of humeral shaft fractures fixed with locking compression plate and those fixed with dynamic compression plate in elderly patients. MATERIALS AND METHODS: Nineteen consecutive elderly patients with a fracture of the humeral diaphysis were evaluated retrospectively. Ten patients had been fixed with LC-DCP, and nine had been fixed with LCP. Radiological and clinical results were compared and comparison of implants was done. RESULTS: Loosening of the plate occurred in one case each from the LCP group and the LC-DCP group. The rest of the patients achieved union uneventfully without any complications. Union rate, clinical score and hardware were not significantly different between the two groups. One patient who developed loosening in the LC DCP underwent reoperation whereas one patient with loosening in the LCP was successfully managed conservatively. CONCLUSION: Principle of fracture fixation was more important than plate selection in humeral shaft fracture of elderly patient.

Treatment of Two- and Three-Part Fracture of Proximal Humerus using LCP

PURPOSE: To evaluate the result and complication of treatment using Locking Compression Plate (LCP) for fracture of proximal humerus. MATERIALS AND METHODS: Between 2004 and 2006, 21 patients with two-part and three-part fractures of the proximal humerus were treated by LCP fixation. Their average age was 54.9 years. Postoperative mean follow-up period was 22.9 months. The reduction was qualified and complication were assessed with final radiographs. The functional outcome was evaluated by Neer's rating system. RESULTS: By Neer's functional evaluation, mean score of shoulder function was 86.3 and 18 case (86%) had excellent or satisfactory results. There was one case of nonunion but no infection or avascular necrosis of the humeral head. No correlation was found between the final result and the type of fracture, age, gender or quality of reduction. CONCLUSION: We obtained satisfactory result of LCP fixation for fracture of proximal humerus in this study. LCP fixation for proximal humerus fracture is a reliable method to obtain satisfactory reduction, rigid fixation and early exercise.
