Uso de placa malla en el manejo de fracturas conminutas de patela: reporte de caso / Use of mesh plate for the treatment of comminuted patellar fractures: case report

OBJETIVOS Describir la técnica quirúrgica para el uso de placa malla en un caso de fractura conminuta de patela y sus resultados en el seguimiento a mediano plazo. MATERIALES Y MÉTODOS Presentamos un caso de fractura conminuta de patela manejada con el uso de una placa malla y un tornillo canulado asociado, evitando de esta forma la patelectomía parcial y sus posibles complicaciones. RESULTADOS El paciente presentó una evolución satisfactoria, con rango de movimiento de rodilla completo y en condiciones de alta laboral a los cuatro meses desde la cirugía, sin complicaciones ni reintervenciones. DISCUSIÓN El uso de placas malla permite el manejo de fracturas conminutas de patela preservando stock óseo y restaurando la indemnidad del aparato extensor, con una osteosíntesis estable y poco prominente. Casos en que antiguamente la única alternativa era la patelectomía parcial y reinserción del tendón patelar ahora tienen etas placas como opción de manejo. CONCLUSIÓN El uso de placas malla en fracturas conminutas de patela es una alternativa atractiva por la estabilidad que brindan, la capacidad de reservar stock óseo, y la baja tasa de reintervenciones

OBJETIVE To describe the surgical technique for the use of a mesh plate in a case of comminuted patellar fracture and the mid-term follow up outcomes. MATERIALS AND METHODS We present a case of comminuted patella fracture managed with the use of a mesh plate and an associated cannulated screw, thus avoiding partial patellectomy and its possible complications. RESULTS Four months postoperatively, the patient presented full knee range of motion and could be discharged to return to work, with no complications or reinterventions. DISCUSSION The use of mesh plates enables the management of comminuted patellar fractures preserving bone stock and restoring the extensor mechanism with a stable and little prominent osteosynthesis. Cases which previously would only have been treated by partial patellectomy and patellar tendon reinsertion can be treated with these plates. CONCLUSION The use of mesh plates for comminuted patellar fractures is an attractive option due to their stability, their ability to preserve bone stock, and the low rates of reintervention.

Tratamiento de la fractura conminuta de patela: ¿existen diferencias entre realizar o no una eversión? / Treatment of comminuted patellar fracture: are there differences between performing or not performing an eversion?

OBJETIVO Comparar los resultados clínicos, funcionales e imagenológicos de dos técnicas quirúrgicas para el manejo de fracturas conminutas de patela: con y sin eversión patelar. MÉTODOS En una serie de casos retrospectivos de fracturas conminutas de patela tratadas en el mismo centro entre 2014 y 2017, con un seguimiento ≥ 3 meses, se hizo una comparación entre el grupo con eversión y el grupo sin eversión. Los criterios de exclusión fueron patelectomía parcial o total, reinserción tendínea, o rehabilitación incompleta. Las variables analizadas fueron edad, sexo, tabaquismo, diabetes mellitus, energía del accidente, tipo de fractura, variables quirúrgicas (banda de tensión, tornillos, alambres, nudos, cerclaje circular), rango de movimiento (RDM) articular postoperatorio, presencia de osteosíntesis sintomática, puntaje de escalas funcionales (de Tegner-Lysholm y de Kujala) al alta definitiva, complicaciones (rigidez articular, infección, trombosis venosa profunda), y variables imagenológicos con tomografías computarizadas pre- y postoperatorias (brecha, desnivel articular > 2 mm, elementos de fijación intraarticular). RESULTADOS En total, 20 de 22 pacientes, 13 con eversión y 7 sin eversión, cumplieron con los criterios de selección. El seguimiento fue de 3 a 12 meses, y no hubo diferencias estadísticamente significativas respecto a las variables demográficas entre ambos grupos, lo cual los hace comparables. Destacaron el tiempo desde el ingreso al alta, con 7 meses para los pacientes con eversión y 5 meses para los sin eversión (p = 0.032), la proporción de pacientes con desnivel articular > 2 mm, con 7.7% para los con eversión y 14.3% para los sin eversión (p = 0.016), y una tendencia a resultados superiores en escalas funcionales para el grupo con eversión. CONCLUSIÓN El tratamiento de fracturas conminutas de patela con eversión parece ser una alternativa viable dados sus resultados imagenológicos y funcionales superiores a los de la técnica habitual.

PURPOSE To compare the clinical, functional and imaging outcomes of two surgical techniques for the treatment of comminuted patellar fractures: with and without eversion. METHODS In a retrospective series of cases of comminuted patellar fractures treated at a single center between 2014 and 2017, with a follow-up 3 months , we performed a comparison between the eversion group and the non-eversion group. The exclusion criteria were partial or total patellectomy, tendon reinsertion, or incomplete rehabilitation. The variables analyzed were age, gender, smoking, diabetes mellitus, the energy of the accident, the fracture type, surgical variables (tension band, screws, wires, knots, circular cerclage), postoperative joint range of motion (ROM), presence of symptomatic osteosynthesis, the scores on the functional scales (of Tegner-Lysholm and of Kujala) at the final discharge, complications (joint stiffness, infection, deep vein thrombosis), and pre- and postoperative computed tomography imaging variables (gap, step-off > 2mm, intra-articular fixation elements). RESULTS In total, 20 out of 22 patients, 13 undegoing eversion and 7 not undergoing eversion, met the selection criteria.. The follow-up ranged from 3 to 12 months, and there were no statistically significant differences regarding the demographic variables between both groups, which makes them comparable. The most remarkable results were the time from admission to final discharge, of 7 months for the patients in the eversion group, and of 5 months for those in the non-eversion group (p » 0.032), the proportion of patients with a step-off > 2 mm, with 7.7% for the eversion group and 14.3% for the non-eversion group (p » 0.016), and a tendency towards higher scores in the functional scales for the eversion group. CONCLUSION The treatment of comminuted patellar fractures with eversion seems to be a viable alternative, given its superior imaging and functional results compared to those of the usual technique.

Objective To investigate the effect of minimally invasive plate osteosynthesis combined with locking compression plate fixation on postoperative fracture healing and serum levels of and serum nerve growth factor (NGF),vascular cell adhesion molecule (s VCAM),alkaline phosphatase (ALP) in patients with limb comminuted fracture.Methods From January 2014 to May 2016,seventy-four patients with limb comminuted fracture in the Eighth People's Hospital of Shanghai were enrolled in this study and randomly divided into the control group (37 cases) and the study group (37 cases).The traditional incision and reduction fixation were used in the control group.The study group was treated with locking compression plate internal fixation combined with minimally invasive plate bone grafting technique.The patients were followed up for 1 ～ 4 months after operation.The clinical efficacy,perioperative indicators (operation time,intraoperative blood loss,fracture healing time),serum (nerve growth factor,vascular cell adhesion molecule,alkaline phosphatase) levels change at the time of admission and after first D and complications rate were statistically compared.Results The total effective rate of the study group was 97.30％ (36/37),higher than that in the control group (78.38％ (29/37)),and the difference was statistically significant (x2 =4.554,P＜0.05).The operation time of the study group was (84.76 ± 11.08) min,longer than that of the control group ((71.89 ± 10.54) min),the intraoperative blood loss of the study group ((108.52 ± 21.33) ml) was less than that of the control group ((245.30±24.61) ml),and the fracture healing time of the study group ((9.04 ± 1.81) weeks) was shorter than that of the control group ((12.79 ±2.02) weeks),and the difference was statistically significant (t =5.119,t =25.547,t =8.410,P＜ 0.05).The levels of serum NGF,s VCAM and ALP in the two groups after operation were higher than those before operation,and the levels of serum NGF ((1.33±0.19) ng / L) and ALP ((312.04±31.07) U/L) in the study group were higher than those in the control group ((0.85 ± 0.22) ng/L,(181.28±30.45) U/L),and the level of serum s VCAM ((502.18±40.07) μg/L) was lower than that in the control group ((579.28 ± 41.15) μg/L),and the difference was statistically significant (t =10.044,18.283,8.165,P＜0.05).The incidence of complications in the study group was 8.11％ (3/37),lower than that in the control group (27.03％ (10/37)),the difference was statistically significant (x2 =4.573,P ＜ 0.05).Conclusion Minimally invasive plate osteosynthesis combined with locking compression plate fixation in the treatment of limb comminuted fracture can shorten the healing time of the fracture,improve the treatment effect,improve the levels of serum NGF,s,VCAM and ALP,and it have lower complication rate with higher safety.

Mini locked-plate trans-carpometacarpal joint internal fixation for treating comminuted fracture of base of the fifth metacarpal / 中国修复重建外科杂志

Objective: To evaluate the effectiveness of open reduction and trans-carpometacarpal joint internal fixation with mini locked-plate for treatment of comminuted fracture of base of the fifth metacarpal. Methods: Between July 2015 and December 2017, 8 cases of comminuted fractures of base of the fifth metacarpals were treated with open reduction and trans-carpometacarpal joint internal fixation with mini locked-plate. There were 7 males and 1 female with an age of 19-45 years (mean, 32.5 years). The causes of injury included 2 cases of hitting hard objects while clenching fist, 6 cases of falling injury. There were 2 cases of subluxation of fifth carpal joints and 1 case of dislocation. The time from injury to operation was 1-5 days (mean, 3.5 days). The stability of fracture ends could not be maintained by preoperative evaluation without over articular fixation or short time over articular fixation. Postoperative complications and fracture healing were observed, and hand function was evaluated at last follow-up according to the total active motion (TAM) recommended by the Branch of Hand Surgery of Chinese Medicine Association. Results: All the incisions healed by first intention without complications such as wound infection, cutaneous necrosis, tendon or nerve injury. All the patients were followed up 6-18 months (mean, 12 months). All fractures healed with the healing time of 12-16 weeks (mean, 13 weeks). Within 4 months after operation, all patients were able to return to pre-injury job. At last follow-up, according to the TAM recommended by the Branch of Hand Surgery of Chinese Medicine Association, the results were excellent in 7 cases, good in 1 case, with the excellent and good rate of 100%. Conclusion: Applying of mini locked-plate for treatment of comminuted fractures of base of the fifth metacarpal, of which cannot obtain stable fixation through non-transarticular or short-time transarticular fixation, can achieve satisfactory functional results with very few complications through trans-carpometacarpal joint approach, thus the procedure can be used as an alternative operation scheme.

Comparison of the Result of the Intramedullary Nail Fixation and Plate Fixation in Humeral Shaft Fracture with Butterfly Fragments / 대한스포츠의학회지

First aim of this study was to compare the results of the intramedullary nail fixation and plate fixation for the management of humeral shaft fracture with butterfly fragments. Second aim of this study was to appraise the necessity of anatomical reduction and fixation for butterfly fragment in humeral shaft fracture. Thirty-one patients with comminuted humeral shaft fracture were treated by reduction and internal fixation with intramedullary nail or plate. The criteria for inclusion were AO classification type B, follow-up period more than 12 months, diaphyseal fracture without involvement of joints. Eighteen patients underwent intramedullary nail fixation and 13 by plate fixation. The outcome was assessed in terms of the union rate, union time, incidence of complications, and functional outcome of shoulder joint. The union rate was 94.4% in intramedullary nail group and 100% in plate group. The average union time was found to be no significant difference between two groups (p>0.05). There was no significant difference in the American Shoulder and Elbow Surgeons' score and range of motion of shoulder and elbow joint between the two groups in last follow-up (p>0.05). The union rate and average union time and functional outcome of shoulder joint was no significant difference between the intramedullary nail fixation and plate fixation for the management of humeral shaft fracture with butterfly fragments. It is recommended to select skillful technique to avoid technical errors rather than technique to fix of butterfly fragments.

Use of Composite Wiring on Surgical Treatments of Clavicle Shaft Fractures

PURPOSE: To introduce the technique of reducing displaced or comminuted clavicle shaft fracture using composite wiring and report the clinical results. MATERIALS AND METHODS: Between March 2006 and December 2013, 31 consecutive displaced clavicle fractures (Edinburgh classification 2B) treated by anatomic reduction and internal fixation using composite wiring and plates were retrospectively evaluated. The fracture fragments were anatomically reduced and fixed with composite-wiring. An additional plate was applied. Radiographic assessments for the numbers of fragments, size of each fragment and amount of shortening and displacement were performed. The duration for fracture union and complications were investigated retrospectively. The mean fallow-up duration was 15.9 months. RESULTS: The mean number of fragments was 1.7 (1-3) and the mean width of fracture fragment was 7.1 mm (4.5-10.6 mm). The mean shortening of the clavicle was 20.5 mm (10.3-36.2 mm). The mean number of composite wires used in fixation was 1.9 (1-3). Radiographic union was achieved in all patients with a mean time to union of 11.6 weeks. There were no complications including metal failure, pin migration, nonunion, or infection. CONCLUSION: The composite wiring was suitable for fixation of small fracture fragment and did not interfere with the union, indicating that it is useful for treatment of clavicle shaft fracture.

Treatment of Tibial Fractures by Ilizarov Technique: A Longitudinal Study.

Introduction: Ilizarov technique has many advantages over conventional orthopedic treatment of fractures. It is minimally invasive and permits accurate reduction and alignment of comminuted, diaphyseal, and juxta-articular fractures. Acute infections following immediate fixation with nail or plate can be effectively managed with Ilizarov fixator. Materials and Methods: In the present study, twenty patients with tibia fractures were operated with Ilizarov over a period of 2 consecutive years and the results were analyzed. Fixator used is Ilizarov external fixator with Schanz pins and tensioned wires. Results: Results were assessed using bone score (ASAMI) and lower extremity functional scale. 68.4% had excellent, 15.8% patients had good, 5.3% patients had fair, and 10.5% patients had poor result. 57.9% patients had minimal disability, 26.3% patients had moderate disability, 10.5% patients had severe disability, and 1 patient crippled. Conclusion: Ilizarov circular fixation is an ideal method for fracture when extensive dissection and internal fixation are contraindicated due to trauma to soft tissue, deficiency of bone stock, infection, and comminuted fracture.

Anatomical Reduction of All Fracture Fragments and Fixation Using Inter-Fragmentary Screw and Plate in Comminuted and Displaced Clavicle Mid-Shaft Fracture

PURPOSE: To report the treatment results of anatomical reduction of all fracture fragments and internal fixation using an inter-fragmentary screw and plate in displaced mid-shaft clavicle fracture with comminution. MATERIALS AND METHODS: Between June 2005 and August 2011, 13 consecutive displaced clavicle fractures with comminution (Edinburgh classification IIB2) treated by anatomic reduction and internal fixation using inter-fragmentary screw and plate were retrospectively evaluated. There were 11 male and 2 female patients with a mean age of 37.4 years (15~55 years). The right clavicle was injured in 4 patients and the dominant arm was involved in 46%. The mean duration from trauma to surgery was 7.0 days. The cause of injury was a traffic accident in three, a fall in two, and sports activity or direct injury in eight patients. All of the fracture pieces were anatomically reduced and fixed with inter-fragmentary screws. An additional plate was applied to maintain and reinforce the reduction of the fracture. Radiographic assessments for the numbers of fragments and the amount of shortening and displacement were performed. To verify the fracture healing and determine the time from fracture surgery to union and complications, all of the radiographs taken after surgery were evaluated. RESULTS: The number of fragments was 2 in 7 cases, 3 in 5 cases, and 6 in one case. The mean shortening of the clavicle was 1.1 cm (0.3~2.1 cm) and mean displacement between the main fragments was 2.6 cm (1.3~4.5 cm). The mean duration of follow-up was 16.5 months (8~26 months). Radiographic union was achieved in all patients with a mean time to union of 10.8 weeks (8~14 weeks). There were no complications including metal failure, nonunion, or infection. CONCLUSION: Anatomical reduction of all the fracture fragments and fixation using inter-fragmentary screws in addition to the usual plate fixation showed good fracture healing in displaced clavicle fracture with comminution.

Versatility of n-butyl-2-Cyanoacrylate for the Reconstruction of Frontal Sinus Comminuted Fracture in Children

PURPOSE: In treatment of facial bone fracture, occurred in children, we generally use wires, miniplate, absorbable plate or their combination. These foreign bodies can be palpable, and sometimes may cause infections, and need reoperation for removing. When bone fragments are multiple, small or thin, they are hard to handle and make accurate reduction of all fragments. In these cases, a biodegradable tissue adhesive, Histoacryl(R) (n-butyl-2-cyanoacrylate), can be used as fixation technique for small, multiple, and thin fracture fragments. METHODS: 3 years old and 6 years old children, who has comminuted fracture on frontal sinus, we used Histoacryl(R) for fixation of multiple bone fragments. After approaching by coronal incision, we pulled out all bone fragments and reconstructed bone fragments by Histoacryl(R) and fixed those on frontal sinus by absorbable plates. RESULTS: Photographs and 3-dimensional CT obtained preoperatively and postoperatively. And we compared them each other in terms of accuracy of reconstructed bony contour. We could reconstruct almost all bone fragments easily along 3-dimensional structure and get excellent aesthetic results. There was no complication such as infection. CONCLUSION: In treatment of comminuted facial bone fracture, occurred in children, Histoacryl(R) is an excellent method for accurate reconstruction in small and thin bone fragments which cannot be fixed by wire, miniplate or absorbable plate without complication.

Operative Treatment of Distal Humeral Comminuted Fractures with Orthogonal Plating

PURPOSE: To analyze the results of operative treatment for Comminuted Fracture of Distal Humerus with Transolecranon approach and Orthogonal plating. MATERIALS AND METHODS: The subjects were 22 patients with Comminuted fracture of humerus who were treated with Orthogonal plating. Patient's age, sex, type of fracture, surgical approach, method of fixation, time of operation, time of bony union, complication, range of motion were investigated, and Function of elbow was evaluated by functional evaluation of Riseborough and Radin, Mayo Elbow Performance Score (MEPS). RESULTS: Age, sex, injuried arm, operation time were not related to postoperative result. Type C2 fractures showed better results in function and range of motion (ROM) than type C3 fractures. Also early rehabilitation was important to functional recovery and ROM. The postoperative ROM was average 110. Good were 16 cases, fair were 6 cases in functional evaluation of Riseborough and Radin. Excellent were 13 cases, good were 8 cases, fair was 1 case in MEPS. CONCLUSION: Operative treatment with Transolecranon approach and Orthogonal plating showed favorable result on its function. Intraarticular comminution and early rehabilitation were closely related to postoperative function of elbow.

Does Interfragmentary Cerclage Wire Fixation in Clavicle Shaft Fracture Interfere the Fracture Healing?

PURPOSE: A technique of cerclage wire fixation in comminuted fracture of the clavicle shaft is thought to interfere the fracture healing, so authors studied radiographically and clinically about the cases of cerclage wiring of the fracture fragments with the plate and screws fixation in the comminuted fracture of the shaft of the clavicle. MATERIALS AND METHODS: According to following inclusion criteria, total 18 patients (male: 15, female: 3) were investigated; Patients who visited hospital due to clavicle shaft comminuted fracture from February 2005 to April 2009, who underwent surgery utilizing more than 2 cerclage wire fixation for the fragments when open reduction and plate fixation were operated and who could be follow-up over one year. The duration for fracture union, functional outcome and complications were investigated retrospectively. RESULTS: Radiological bone union was accomplished in average 13.3 weeks (12~16 weeks) and there was no complication such as nonunion, delayed union or infection. Range of motion of ipsilateral shoulder joint was recovered in all patients except one at the final follow-up. CONCLUSION: The clinical and radiographical results of the plate and screws fixation with cerclage wiring of the fragments in comminuted clavicle shaft fracture showed that the cerclage wiring does not interfere the fracture healing, so authors think that this method is a good alternative operation if it is performed carefully to minimize soft tissue dissection.

Dual Miniplate Fixation for the Comminuted Fractures of the Hand

PURPOSE: The objective of this study was to evaluate clinical results of dual miniplate fixation for comminuted or periarticular fractures of the hand. MATERIALS AND METHODS: Twenty cases in 18 patients who had comminuted or periarticular fractures of metacarpal or phalangeal bones were treated with dual miniplate fixation from April, 2007 to May, 2009. The mean followed up period was 14.7 months. Our study included comminuted or periarticular fractures which were difficult to keep the fixation by pining or single plating. We evaluated radiologic bony union, angular or rotational deformity, extensor tendon irritaion and total arc of motion. RESULTS: Bony union was achieved successfully after primary dual miniplate fixationin in 12 cases. In 7 cases with a nonunion following previous operative fixation, bony union was obtained by dual miniplate fixation and bone grafting. In one case who had received primary dual plate fixation, nonunion occurred due to massive bone defect. Bony union was obtained by secondary dual plate fixation and bone grafting. Postoperative rotational deformity, angular deformity and irritation symptom were not observed in all cases. Functionally acceptable range of active motion was restored by way of early active motion. CONCLUSION: The dual miniplate fixation is one of the useful method for comminuted metacarpal or phalangeal fractures which cannot obtain firm fixation by other methods.

The Short Term Clinical Follow-up Study for Hemiarthroplasty in Proximal Humeral Fracture

Introduction: The treatment of proximal humeral fracture is traditionally determined by Neer's classification system. The severely displaced three-part or four-part fracture is an indication for primary hemiarthroplasty. The current authors report the clinical results of 10 patients who received hemiarthroplasty for proximal comminuted fractures. The minimum follow-up period was 12 months. Materials and Methods: The current authors studied 10 patients who, between July 1999 and March 2005, each received hemiarthroplasty for a proximal humeral fracture of one shoulder. According to Neer's classification system, 5 of the patients had three-part fractures, and 5 of the patients had 4-part fractures. The mean interval between trauma and hemiarthroplasty was 6.1 days. The mean age of the 6 female and 4 male patients was 67.4 years (range: 56 to 76). Shoulder function was evaluated using the Constant score, the Simple Shoulder Test, and the modified UCLA score. Results: The mean Constant score was 51.4(range: 34 to 60). The mean modified SST score was 7.8 out of 12 tasks. Excluding the one patient who had also sustained an axillary artery rupture and a brachial plexus injury after the initial trauma, the mean Constant score for the remaining 9 patients was 53.5(range: 44 to 60), and the mean SST score was 7.2 tasks. The modified UCLA score averages for pain, function, and active forward flexion and strength were, respectively, 8.2(6~10), 6.6(2~8), and 6.9(4~8). The total UCLA score was an average of 21.7(12~26). Patients' the modified UCLA ratings were as follows: Excellent: 3, Good: 6, and Poor: 1. The patient with the poor outcome was the one who had also sustained the neurovascular injury. Patient's subjective satisfaction rating were as follows: Excellent: 2, Good: 7, and Poor: 1. Conclusion: Based on short term follow-up results, this study indicates that hemiarthroplasty is the treatment of choice for proximal humeral fractures on which it would be difficult to perform open reduction and internal fixation. Hemiarthroplasty is a useful treatment modality to prevent shoulder stiffness and to allow daily living tasks in elderly patients. However, restoration of muscle power and range of joint motion were not recovered satisfactorily.

Research advance of fixation of tibiofibular comminuted fracture / 中国矫形外科杂志

The characteristics and purpose of treatment of tibiofibular comminuted fracture is reviewed in this paper.The present points of view is that tibiofibular comminuted fracture is a kind of smash fracture,that is valuable for restoring its tubular structures.The appearance of a series of new type plates and external fixations represents the trend of researching.The combination of internal/external-fixation and sequential treatment is waited for more research.
