Tratamiento Ortopédico de las Fracturas de Cóndilo Mandibular A Propósito de Tres Casos / Orthopedic Treatment for Mandibular Condyle Fracture: A Three Case Series

RESUMEN: Las fracturas de cóndilo mandibular son frecuentes en el trauma maxilofacial. Pueden tratarse ortopédicamente o en forma quirúrgica, dependiendo principalmente de las características morfológicas y funcionales del caso, y también de la experiencia del cirujano y los recursos disponibles. En los últimos años se ha establecido una corriente proclive al tratamiento quirúrgico, basada en la rápida recuperación del enfermo y la disminución de las secuelas funcionales y estéticas. Sin embargo, el tratamiento ortopédico bien indicado y ejecutado, puede ser una buena alternativa de tratamiento y que debe ser considerada dentro de las propuestas terapéuticas. El Objetivo de este estudio, es presentar una serie de tres casos de pacientes afectados por fracturas de cóndilo mandibular, tratados en forma ortopédica, en el Hospital El Carmen Dr. Luis Valentín Ferrada, Santiago - Chile. Además, se presentará una revisión de las dos tendencias de tratamiento con énfasis en las indicaciones y protocolo adecuado de tratamiento ortopédico.

ABSTRACT: The Mandible condyle fracture, are common in maxillofacial trauma. They can be treated orthopedically or surgically, depending on the characteristics of the case, the available means and the experience of the surgeon. In recent years, a trend has been established that is prone to surgical treatment, based on the patient's rapid recovery and the reduction of aesthetic and functional sequelae. However, orthopedic treatment can be an excellent treatment alternative. This is why today the treatment of mandibular condyle fractures has become a controversy in the specialty. The objective of this report is to present a series of three cases of patients with mandibular condylar fractures, treated orthopedically, at the Carmen Clinical Hospital, Santiago - Chile. In addition with a brief review of the two treatment trends will be presented with emphasis on the indications and appropriate protocol of orthopedic treatment.

Internal fixation of in situ femoral condyle fractures assisted by CT scanning for 3D reconstruction and 3D printing / 中华创伤骨科杂志

Objective To investigate the efficacy of CT scanning for 3D reconstruction and 3D printing in the internal fixation for in situ femoral condyle fractures.Methods A retrospective study was conducted of the 111 patients with in situ femoral condyle fracture who had been treated by internal fixation at Department of Traumatic Orthopaedics,The First People's Hospital of Hefei from June 2013 to January 2018.They were 59 males and 52 females,aged from 20 to 59 years(average,47 years).In 74 of them (observation group),the internal fixation was assisted by 3D printing using 3D images.There were 38 males and 36 females with an age of 44.5 ±4.7 years;there were 20 cases of type C1,40 cases of type C2 and 14 cases of type C3 according to the AO classification.In the other 37 patients (control group),the operation was assisted only by 3 D scanning.There were 21 males and 16 females with an age of 43.1 ±4.6 year;there were 8 cases of type C1,19 cases of type C2 and 10 cases of type C3 according to the AO classification.The 2 groups were compared in terms of operation time,clinical fracture healing time,intraoperative blood loss,hospital stay,number of fluoroscopy,knee joint score of Hospital for Special Surgery (HSS),fixation modes and postoperative complications.Results There were no significant differences in the preoperative general data between the 2 groups,showing comparability (P ＞ 0.05).All the patients were followed up for 8 to 12 months (average,10.6 months).The observation group had significantly shorter operation time (62.3 ± 4.7 minutes),fracture healing time (21.2 ± 3.4 weeks) and hospital stay (14.9 ± 3.3 days) than the control group (89.5 ± 6.0 minutes,25.1 ± 3.5 weeks,23.5 ± 3.5 days) (P ＜ 0.05).In the observation group,the intraoperative blood loss (84.1 ± 11.1 mL),fluoroscopy number (2.1 ±0.3 times) and HSS score (94.1 ± 4.2 points) were significantly less than those in the control group (129.6 ± 14.7 mL,4.7 ± 0.4 times and 86.5 ± 4.6 points) (P ＜ 0.05).There were no significant differences between the 2 groups in the use of L type iliac plate,dynamic iliac screws,retrograde interlocking intramedullary nail or minimally invasive internal fixation system (P ＞ 0.05).There were no significant differences in abnormal healing,joint adhesion,fixation fracture or incision infection between the 2 groups either (P ＞ 0.05).Conclusions CT scanning for 3D reconstruction can be used for multi-angle observation of the bone fragments in patients with femoral condyle fracture and 3D printing based on 3D reconstruction for manufacture of physical model of individualized fracture to assist the internal fixation.Combination of the two can help choose an appropriate fixation mode to facilitate fracture reduction.

Occipital Condyle Fractures in Traumatic Brain Injury­A Review / Fraturas de côndilo occipital no trauma cranioencefálico ­ uma revisão

É bem estabelecido que o diagnóstico da fratura de côndilo occipital tem aumentado nas últimas décadas, provavelmente devido à disponibilidade e ao uso comum da tomografia computadorizada durante a investigação do trauma craniano, além da maior gravidade dos mecanismos de trauma. Por causa da baixa especificidade da apresentação clínica, e também pelo pouco conhecimento sobre o mecanismo de lesão, o diagnóstico desta condição é um desafio para neurocirurgiões. A abordagem terapêutica destes pacientes é baseada em estudos com baixa casuística e em relatos de caso. Uma revisão sobre este tema foi realizada a fim de discutir alguns aspectos controversos sobre o manejo da fratura de côndilo occipital. As fraturas de côndilo occipital são eventos raros, entretanto podem relacionar-se à alta morbidade em pacientes que sofreram trauma encefálico. Alguns sintomas, como intensa dor cervical, podem estar associados com esta fratura; portanto, paciente com suspeita de fratura de côndilo occipital deve ser submetido a investigação radiológica detalhada da região. O diagnóstico precoce desta fratura permite investigação apropriada, minimizando a chance de sequelas.

It is well established that diagnoses of occipital condyle fracture have increased in past decades, probably because of the availability and common use of computed tomography for investigating traumatic brain injuries, as well as themajor seriousness of trauma mechanism. Because of the low specificity of clinical presentation besides the lesion mechanism not well known, this condition is a diagnostic challenge for neurosurgeons. Therapeutic approaches of these patients are based on studies with low samples and case reports. A review of this theme was performed objecting to discuss some controversial topics about management of occipital condyle fracture. The occipital condyle fracture is a rare event, and it, however, could be related to high morbidity in patients who suffered traumatic brain injury. Some symptoms such as severe neck pain are related with this fracture, and thus patients suspicious of this fracture should undergo detailed radiologic investigation of this region. Early diagnosis of this fracture allows appropriate investigation, thus minimizing the risk of sequelae.

Fratura de côndilo mandibular em criança: tratamento ortopédico-funcional / Fracture of Condyle Mandibular in Children: Functional Orthopedic Tretment

As fraturas de côndilo mandibular são as mais freqüentes do osso mandibular, tendo uma prevalência de 34 a 45%, e eventualmente ocorrem em jovens e adultos. O tratamento dessas fraturas é controverso, indo desde o tratamento funcional ortopédico a redução com fixação dos cotos fraturados de forma aberta. Neste trabalho descrevemos uma técnica conservadora e altamente resolutiva, descrevendo como modelo um paciente de 5 anos de idade, vítima de queda da mesma altura, com fratura alta e cominutiva do côndilo mandibular direito, proporcionando ao mesmo desoclusão dental, assimetria facial, artralgia e dificuldade de abertura de boca. Foi realizado artrocentese e na sequência instalação de aparelho ortopédico do tipo Bimler A, visando intervenção mínima nas articulações epifisárias. O Tratamento teve uma duração clínica de 6 meses e acompanhamento por 2 anos, com resultados extremamente satisfatórios... (AU)

The mandibular condyle fractures are the most frequent of the mandibular bone, having a prevalence 34 - 45%, and generally occur in young adults. The treatment of these fractures is controversial, ranging from functional orthopedic treatment until reduction with fixation of the fractured stumps openly.

Occipital Condyle Fracture With Isolated Unilateral Hypoglossal Nerve Palsy

Occipital condyle fractures (OCFs) with selective involvement of the hypoglossal canal are rare. OCFs usually occur after major trauma and combine multiple fractures. We describe a 38-year-old man who presented with neck pain and a tongue deviation to the right side after a traffic accident. Severe limitations were detected during active and passive range of neck motion in all directions. A physical examination revealed a normal gag reflex and normal mobility of the palate, larynx, and shoulder girdle. He had normal taste and general sensation in his tongue. However, he presented with a tongue deviation to the right side on protrusion. A videofluoroscopic swallowing study revealed piecemeal deglutition due to decreased tongue mobility but no aspiration of food. Plain X-ray film findings were negative, but a computed tomography study with coronal reconstruction demonstrated a right OCF involving the hypoglossal canal. An electrodiagnostic study revealed evidence of right hypoglossal nerve palsy. We report a rare case of isolated hypoglossal nerve palsy caused by an OCF.

Traumatic retroclival epidural hematoma and unilateral occipital condylar fracture in an adult patient

Retroclival epidural hematoma is rare, with fewer than 30 cases reported in the literature. Almost all of the previously reported cases occurred in children, with only a few cases affecting adults. Among these adult patients, only two suffered from the associated occipital condyle fracture (OCF), which is another rare injury. The patient involved in this study suffered from retroclival epidural hematoma and unilateral occipital condyle fracture, as demonstrated on both CT and MRI scans. The patient also suffered from an associated right brachial plexus injury without any other neurological deficits, a condition that has not previously been reported. This paper reviews the underlying mechanisms of these rare injuries and seeks to form an understanding of them before proposing the mechanism of injury in the patient involved in the study

The Treatment for Mandibular Condyle Fracture of Children by a Threaded Kirshcner Wire and External Rubber Traction

PURPOSE: The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications- mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction. METHODS: From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular-maxillary fixations were removed after 3 weeks, and patients were sent to training for mouth opening. RESULTS: The technique didn't result in complications- joint dysfunction, facial nerve injury, sore, infection and nonunion during follow-up period. Radiologic follow-up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function. CONCLUSION: Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.

The Surgical Treatment of Distal Femur Medial Condyle Fracture Using Lateral Anatomical Plate of Opposite Side through Medial Approach

PURPOSE: To evaluate clinical and radiological results of surgical treatment of distal femur medial condyle fracture using lateral anatomical plate of opposite side through medial approach. MATERIALS AND METHODS: This study reviewed the results of 9 cases of distal femur medial condyle fracture treated with lateral anatomical plate of opposite side through medial approach from December 2005 to June 2007, after a follow up of more than 12 months. There were 2 males and 7 females with a mean age of 63.1 (57~72) years. The clinical results were evaluated using the Schatzker's criteria, and the radiographic results were evaluated using the bone union time. RESULTS: Using the Schatzker's criteria, 7 cases of the 9 patients (78%) showed exellent results. The mean time for bone union was 13.4 (11~15) weeks. There were 3 cases of pain on full weight bearing same as previous operative state by degenerative osteoarthritis. There weren't complications as joint stiffness, infection, varus & rotational deformity, malunion, nonunion, and metal failure. CONCLUSION: Plate fixation using medial approach provides the proper anatomical reduction and stronger fixation, and outcome good results.

Surgical Treatment of Late Presented Displaced Lateral Condylar Fracture of the Humerus in Children / 대한정형외과학회잡지

PURPOSE: To determine whether late open reduction and internal fixation (ORIF) of a lateral condylar fracture (LCF) after 3 weeks is possible, and to determine the latest time for ORIF without a bone graft. MATERIALS AND METHODS: Eight children underwent late ORIF (>3 weeks) of a displaced LCF (>2.5 mm) of the humerus between 3 weeks and 5 weeks after injury. RESULTS: Clinically, results were excellent in 6 cases and good in 2 cases. There was no serious complication, including nonunion and avascular necrosis (AVN), though 2 cases had a slight fishtail deformity and mild carrying angle loss due to overgrowth of the lateral condyle fragment. CONCLUSION: We believe that 3 weeks is too short to deny open reduction and anatomic reduction for fear of AVN of a late presented lateral condyle fracture of the humerus. The latest time for ORIF in late presented LCF in children is around 5 weeks, and surgical treatment may even be possible after greater delays.

Open versus closed reduction of mandibular condyle fractures: A systematic review of comparative studies

Objective: The objective of this review was to provide reliable comparative results regarding the effectiveness of any interventions either open or closed that can be used in the management of fractured mandibular condyle PATIENTS AND METHODS: Research of studies from MEDLINE and Cochrane since 1990 was done. Controlled vocabulary terms were used. MeSH Terms were "Mandibular condyle" AND "Fractures, bone". Only comparative study were considered in this review using the "limit" function. According to the criteria, two review authors independently assessed the abstracts of studies resulting from the searches. The studies were divided according to some criteria, and following were measured: Ramus height, condyle sagittal displacement, condyle Towns's image displacement, Maximum open length, Protrusion & Lateral excursion, TMJ pain, Malocclusion, and TMJ disorder. RESULTS: Many studies were analyzed to review the post-operative result of the two methods of treatment. Ramus height decreased more in when treated by closed reduction as opposed to open reduction. Sagittal condyle displacement was shown to be greater in closed reduction. Condyle Town's image condyle displacement had greater values in closed reduction. Maximum open length showed lower values in closed reduction. In protrusive and lateral movement, closed reduction was less than ORIF. Closed reduction showed greater occurrence of malocclusion than ORIF. However, post-operative pain and discomfort was greater in ORIF. CONCLUSION: In almost all categories, ORIF showed better results than CRIF. However, the use of the open reduction method should be considered due to the potential surgical morbidity and increased hospitalization time and cost. To these days, Endoscopic surgical techniques for ORIF (EORIF) are now in their infancy with the specific aims of eliminating concern for damage to the facial nerve and of reducing or eliminating facial scars. Before performing any types of treatment, patients must be understood of both of the treatment methods, and the best treatment method should be taken on permission.

Clinical review of various surgical approaches in the treatment of mandibular condyle fracture

Retromandibular approach for open reduction & internal fixation of mandibular condylar neck fracture

Fractures of the mandibular condyle are account for between 26 percent and 57 percent of all mandibular fractures. Clinicians should decide how to treat the fractured condyle with many factors considered. Many surgical methods have been developed to reduction of fractured condyle and it's internal fixation. In open reduction of fractured condylar neck and subcondyle, retromandibular approach offers a safe and effective approach for direct fixation due to easy access and low surgical morbidity.

Prevalence of Meniscus Tear in Tibial Plateau Fractures

PURPOSE: To evaluate the pattern of meniscal tear according to the type of the tibial plateau fracture of Schatzker. MATERIALS AND METHODS: Sixty two cases of tibial condyle fracture treated between the period of 1994 and 2003 were evaluated. The fracture type was classified according to Schatzker. The pattern and extent of the meniscus tear were compared with the fracture classification. Statistical analysis was made with the Fisher's exact test. RESULTS: Meniscus tear was noted in 29 cases out of 62 fractures (46.8%). The twenty cases of minimally displaced fractures treated conservatively showed no meniscal tear. Of 18 cases of the most common type I fracture 2 (11.2%) had a meniscus tear. Of 16 type II fractures 12 (75%) had a meniscus tear. The type III fracture showed the highest prevalence of meniscus tear (76.9%, 10/13). There was statistically significant relationtionship between the type of fractures and the rate of meniscus tear (p<0.0001). CONCLUSION: The meniscus tear frequently occurred in tibial plateau fractures in Schatzker type II and III. Associated meniscus tears should be born in mind when those types of fracture are encountered.

A Technique for Assist in Positioning the Proximal Segment during Open Reduction of a Fractured Mandibular Condyle

PURPOSE: After exposure of fracture site, the proximal segment must be reduced to their preinjury position for open reduction of fractured mandibular condyle. We examined the use of inter-maxillary fixation screws or titanium screws tied with stainless steel wire to assist in positioning of proximal segment. Since it enables to make a relatively small preauricular incision by not disturbing the operative field like Moule pin, we can reduce the danger of injury to the facial nerve. METHODS: A preauricular approach was used for exposure, reduction, and rigid fixation in 4 cases of mandibular condylar fractures. Inter-maxillary fixation screws or titanium screws tied with stainless steel wire were used to assist in aligning proximal segment. The joints were submitted to functional exercises and postoperative radiologic and clinical follow-ups were performed. RESULTS: No facial nerve lesions were found in all 4 cases. Radiologic follow-up showed correct reduction and fixation in all 4 cases. Clinical follow-up showed an initial limitation, but normal morbility of the condyle was achieved within 4 months after the operation, with a maximum mouth opening of 34.1+/-5.2 mm after 12 months. There found no occlusal disturbances, no trismus, no lateral deviations of the mandible. CONCLUSION: By using Inter-maxillary fixation screws tied with stainless steel wire, it was shown that reducing the proximal segment to their preinjury position is easy to perform and it enables us to make a minimal dissection below preauricular skin incision to avoid facial nerve injury.

Fine Classification and Treatment Outcome of Lateral Condyle Fracture of the Humerus in Children / 대한정형외과학회잡지

PURPOSE: This paper reports the outcome and complications of a lateral condyle fracture of the humerus in children treated by the fine classification of Jakob stage. MATERIALS AND METHODS: Forty-five cases of a lateral condyle fracture of the humerus in children were treated according to the fine classification of the Jakob stage. There were 4 cases of Jakob stage Ia fractures treated with the application of a simple cast; 16 cases of Jakob stage Ib & IIa fractures treated with a closed reduction and k-wire pinning; and 25 cases of Jakob stages IIb & III fractures treated with an open reduction and K-wire pinning. The average follow-up period was 25 months. RESULTS: Postoperative complications were seen in 18 cases. As minor complications, there were 2 cases of delayed union, 5 cases of hypertrophy of the lateral condyle and 10 cases of osteophyte formation. As major complications, 1 case of avascular necrosis and limitation of motion developed. There were no serious complications such as nonunion, malunion, ectopic ossification, early arrest of the growth plate, and nerve injury. The clinical outcomes were excellent in all but one case of a joint motion limitation. CONCLUSION: The fine classification of the Jakob stage is effective in determining the treatment method for lateral condyle fractures of the humerus in children.

Open Reduction of Mandibular Condyle Fracture with Modified Ellis' Technique

Condylar and subcondylar fractures constitute 26-49% of all mandible fractures. There are two principal treatments in these fractures: closed and open reduction. Closed reduction is adopted most frequently. However, there are many reports about the sequelae of closed reduction such as occlusal disruption, varying degree of nonunion and arthritic change, etc. There have been many papers describing advantages of the surgical treatments. In 1989, Ellis et al. reported a new technique for subcondylar fracture. In severe anteromedial fracture dislocations where the condylar head is not retrievable, they recommended a submandibular incision and a vertical ramus osteotomy followed by removal of osteotomized segment. After rigid fixation between the ramus and condylar head, the union was returned as a free bone graft, and the osteotomy site was plated. During their original procedure, however, there are possibility of injury to the inferior alverolar nerve because the distance from posterior cortex of ramus to the canal for nerve has been reported 12.1mm. In this study we modified the Ellis' method to avoid injury to the nearby inferior alveolar nerve. Our method, slight oblique vertical osteotomy of ramus from the sigmoid notch to 1 cm above from the gonion and short horizontal osteotomy, was applied to treat most cases where there are indications for open reduction, contrary to the original indication. Six patients were treated using our method. After 3 months follow-up, the maximal mouth opening showed 39.3cm, protrusion 5.6, lateral deviation 14.3(homolateral side), and 12.2(contralateral side). The occlusal states became good without openbite and crossbite. In this study, we could have satisfactory results from our modified procedure applying to most cases where closed reduction cannot be used or cannot guarantee restoration of TMJ integrity.

Retrospective study for prognosis after open and closed reduction of the mandibular condyle fractures

0.05). The level of the fracture influenced the ramus length and the degree of coronal change in the closed reduction group(P0.05). From the results obtained in this study, fractured mandibular condyles, were treated by closed reduction, had a tendency that continuous condylar displacement was occurred with aspect to horozontal and coronal plane in treatment period including intermaxillary fixation. And then there was a correlation between the level of the fracture and the position change in close reduction group statistically. These result suggested that care must be taken in basing treatment decisions on the degree of displacement of the condyle and in treating the mandibular condyle fractures for a long time.
