Minimally invasive osteosynthesis for clavicular fracture with locked plate / Osteossíntese minimamente invasiva para fratura da clavícula com placa bloqueada

ABSTRACT Objective: To evaluate the clinical and radiographic results of the surgical treatment of fractures of the middle third of the clavicle, using the technique of minimally invasive plate osteosynthesis (MIPO) with locking. Methods: Prospective case series, evaluating displaced fractures of the middle third of the clavicle submitted to MIPO with locking, with procedures performed by a single surgeon. Patients were evaluated at 12 months using the University of Los Angeles (UCLA) scale and anteroposterior radiographs of the clavicles with 45° cranial and caudal inclination, as well as reporting complications. Results: In total, 15 patients were evaluated. The median of surgical time was 50 minutes (IQR 35). The UCLA scale had a median of 35 (IQR 2) at 12 months. All patients presented fracture healing. Minor complications occurred in three cases (20%), with two (13.3%) evolving with plate prominence and one (6.7%) with local paresthesia, while major complications occurred in only one case (6.7%), with suture dehiscence requiring surgical re-approach. Conclusion: MIPO with locking is a viable option for the treatment of displaced fractures of the middle third of the clavicle, with excellent results according to the UCLA scale, fracture healing in all cases, and a low rate of complications. Level of Evidence IV, Case Series.

Mid Shaft Clavicle Fractures- Plate vs Titanium Elastic Nail System

It was believed that “all clavicle fractures heal well” is no longer valid. Recent trend is towards operative management, consists of Pre-contoured plate or Titanium Elas?c Nail System(TENS) applica?on. Plate fixa?on remains the mainstay of treatment but Titanium Elas?c Nail System applica?on has gained a?en?on in recent years. This study highlights the comparison between two most common modali?es available for treatment of mid-sha? clavicle fractures. Objec?ves:Compare the func?onal outcome using Neer’s scoring system, radiological outcome and secondary outcomes between two treatment groups. Methods:Pa?ents sa?sfying inclusion criteria were included in our study and randomized into Group A-operated with plate fixa?on and Group B-operated with TENS. Rou?ne postopera?ve protocol and physiotherapy followed. Regular follow up carried out and assessed as per protocol. Results: We had 15 pa?ents in each group by end of our study. There was no significant difference between the two groups in terms of demographics, ?me to surgery, fracture types. Dura?on of hospital stay, mean fracture union ?me were significantly shorter and cosme?cally more sa?sfied in TENS group. Opera?ve ?me, length of incision, periopera?ve blood loss was significantly higher in plate group and length of clavicle be?er restored. Func?onal outcome was excellent with no significant difference between two groups. Conclusion:Both methods return the pa?ents to their pre-injury func?onal levels without significant complica?ons with excellent func?onal outcome. Titanium Elas?c Nail System applica?on has a shorter opera?ve ?me, lesser dura?on of hospital stay, lower infec?on rate and be?er cosme?c outcome sugges?ng this is the preferred method with no comminu?on whereas plate fixa?on is superior in comminuted fractures.

Comparative Evaluation of Efficacy of Interscalene Block vs. Interscalene Block and Superficial Cervical Plexus Block for Fixation of Clavicular Fractures

Introduction: Regional anaesthesia is seldom used forclavicle fractures considering the anatomical location of thebone. We aim to compare the efficacy of two techniques ofregional anaesthesia as sole anaesthesia technique for fixationsof clavicular fractures.Material and methods: 60 Adult patients with claviclefractures were divided randomly in two groups (1 and 2) andwere administered interscalene block (ISB) only or interscaleneblock and superficial cervical plexus block(ISB+SCPB) assole anaesthetic, respectively. Patients were monitored forefficacy of block and adequacy of anaesthesia and analgesiaat the surgical site. Side effects and hemodynamic parameterswere also monitored.Results:. ISB+SCPB provides excellent anaesthesia forclavicle fixation. Only 1 patient in group 2 required GeneralAnaesthesia(GA) whereas in Group 1, 8 patients required someform of supplemental anaesthesia. There was no statisticallysignificant difference in side-effects and hemodynamic profilein both the groups.Conclusion: ISB+SCPB is significantly better than ISB onlyfor anaesthesia for fixation of clavicular surgeries.

Fractura de clavícula distal con cortical superior indemne: cirugía mínimamente invasiva / Distal clavicle fracture with intact upper cortex: minimally invasive surgery

INTRODUCCIÓN Las fracturas de clavícula distal desplazadas son manejadas generalmente de manera quirúrgica dada la alta probabilidad de no-unión con el tratamiento ortopédico. El propósito de este trabajo es evaluar el uso del sistema de fijación con doble botón cortical para la reducción y estabilización de la fractura de clavícula distal que presenten indemnidad de la cortical superior. MÉTODOS: Estudio retrospectivo observacional clínico-imagenológico de pacientes con fractura desplazada de clavícula distal operados con técnica mínimamente invasiva mediante reducción con sistema de fijación con doble botón cortical. Se describe como criterio radiológico de "Cortical Superior Indemne (CSI)" la presencia del rasgo de fractura a 1cm o más, hacia distal desde el tubérculo conoide, identificándose ese criterio como característica necesaria para la indicación del tratamiento propuesto. Se describen las complicaciones post-operatorias, progresión radiológica y resultados funcionales. RESULTADOS: 21 pacientes fueron tratados con esa técnica con un seguimiento promedio de 23,4 meses. No hubo casos de no unión, infección o herida dehiscente y ningún paciente requirió el retiro del dispositivo. Se encontró un Simple Shoulder Test (SST) promedio de 79,4 (66 - 91,7) y QuickDASH de 11 (6,8 - 15,9). El 87,5% de las fracturas desplazadas de clavícula distal tenían indemnidad de la cortical superior. CONCLUSIÓN: La técnica mínimamente invasiva para la reducción y fijación de la fractura de clavícula distal desplazada con botones corticales es una alternativa simple, reproducible, con pocas complicaciones y excelentes resultados funcionales.

BACKGROUND: Displaced distal clavicle fractures are commonly managed through surgery due to a high probability of nonunion with conservative treatments. The purpose of this study is to evaluate the use of Flip-buttons as a minimally invasive method for fixing and stabilizing displaced distal clavicle fractures when the upper cortical it́s intact. METHODS: A retrospective observational study of radiological and clinical results of patients with displaced distal clavicle fracture that were treated with the Flip-button technique. The indication for using this surgical method was based on the radiological criteria of "Intact Upper Cortical (IUC)" described by the authors as the presence of the fracture 1cm or more, distally to de conoid tubercle. Post-operative complications, radiologic and functional progress were recorded. RESULTS: 21 patients were treated with this technique, all with complete bony union. No patients presented infection or wound dehiscence and implant removal was not necessary in any case. The mean follow-up was of 23,4 months. The mean score in Simple Shoulder Test (SST) was 79,4 (66 - 91,7) and a mean QuickDASH of 11 (6,8 - 15,9). 87,5% of all the displaced distal clavicle fractures had IUC. CONCLUSION: The minimally invasive technique for the reduction and fixation of the displaced distal clavicle fracture with cortical buttons is a simple and reproducible alternative, with few complications and excellent functional results.

Nivel de Evidencia: IV

Introduction: Midshaft clavicular fractures represent up to 10% of skeleton fractures. Conservative treatment usually provides good results with low incidence of complications. However, surgical treatment should be considered in displaced, multifragmentary fractures or cases with significant deformity. The purpose of this retrospective case series is to report our experience in the treatment of closed and displaced midshaft clavicular fractures with pre-contoured plates using MIPO technique, to describe the technique and report preliminary functional results. Methods: Retrospective series of 13 patients (11 males [84.6%] and 2 females [15.4%], mean age: 31 years), with closed and displaced midshaft clavicle fractures classified as type 2B according to Robinson (Edinburgh) treated by reduction and internal fixation with pre-contoured plates osteosynthesis using minimally invasive technique (MIPO) between April 2010 and November 2013. Mean follow-up: 13 months (range 11-25). Radiographic and tomographic controls were carried out to assess function using modified Constant-Murley scale, QuickDASH Questionnaire and the visual analogue scale to evaluate pain. Results: Average time to surgery was 8 days, surgical time: 35 minutes, days in hospital after surgery: 1.28. Clinical and radiological consolidation was recorded at 15.2 weeks on average. The average modified Constant-Murley score was 88, QuickDASH 26.9 and visual analogue scale 0.3. No systemic or cosmetic complications were recorded. Conclusion: Minimally invasive plate osteosynthesis (MIPO) in displaced and closed midshaft clavicle fractures represented a reproducible technique with reduced surgical time and acceptable functional scores.

Neonatal Clavicle Fracture: A Review of Fourteen Cases in East Coast Peninsular Malaysia

Introduction: The purpose of this study is to identify the incidence of clavicle fractures in newborn associated with fetal, maternal and process of deliveries in Kuantan General Hospital from June 2012 until January 2014. This study is to determine epidemiological data of clavicle fractures, maternal and baby risk factors associated with clavicle fractures of newborn and its’ outcome. Methods: This is a prospective study. 13 patients were identified to fulfill the inclusion criteria of the study. The data of sociodemographic, associated fetal and maternal risk factors and the outcomes were recorded using proforma. The statistical data analysis was done using SPSS 12.0. Results: Out of 20,257 live births at our centre during the study period, 13 infants were diagnosed to have clavicle fractures, giving an incidence of 0.64 per 1000 live births. There were 5 (38.5%) left, 7 (53.8%) right and one (7.7%) bilateral fracture. All fractures located at the mid shaft of the clavicle and none have associated brachial plexus injuries. All infants were delivered through vaginal delivery (61.5%); five through assisted delivery (instrumental); 2 (15.4%) forcep and 3 (23.1%) vacuum. Two of the babies developed shoulder dystocia. The average birth weight was 3371 grams (SD 0.269) and mean gestational age was 38.7 weeks (SD 1.16). Five of the mothers (38.5%) were primigravida and eight (61.5%) were multigravida in which,7 (53.8%)were healthy without other co-morbidty, 5 (38.5%) having gestational diabetis and one (7.7%) hypertension. The average maternal weight was 62.0 kg and height 1.58 metres with average BMI of 24.16 (3.29SD). All eventually had a complete recovery at 6 weeks with clinical and radiological evident of fracture union. Conclusions: In conclusion, all patients with clavicle fractures were found following vaginal delivery. There were no associations between neonatal clavicle fractures with maternal or baby risk factors. All fractures healed without any complications.

Outcome of distal end clavicle fractures treated with locking plates / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>Fractures of the lateral end of the clavicle are relatively uncommon. These fractures are unstable due to the various deforming forces which act on the fragments as well as the small distal fracture fragment. At most times the deforming forces are not taken into consideration, and the fracture is not fixed securely. In this study, we assessed a fixation technique using the precontoured locking plates to find out whether it provided a stable fixation with good functional outcome.</p><p><b>METHODS</b>Totally, 32 patients with lateral end clavicle fracture (Neer's Type II) were included in the study. After the informed consent and preoperative investigations were obtained, open reduction and internal fixation was done using a 3.5 mm precontoured superior locking plate with lateral extension under general anesthesia. Postoperative X-rays were done on day 1 and every 6 weeks after operation, until radiological union was achieved. The postoperative pain was assessed using Visual Analogue Scale (VAS) on postoperative days 1, 2 and 10. Postoperatively arm pouch sling was given for 2 weeks followed by active mobilization. Patients were asked to do their daily routine work and avoid lifting heavy weights. The functional outcome was assessed at the end of 2nd and 6th months with the help of Disabilities of the Arm, Shoulder and Hand (DASH) scoring.</p><p><b>RESULTS</b>There were no intraoperative complications in the procedure. The mean VAS score on postoperative day 1 was found to be 5 which decreased to 3 on day 2 and 0 on day 10. The mean DASH score was calculated as 11.63 at the end of postoperative month 2 and then 4.6 at the end of month 6. There was one case of malunion in whom the overhead abduction was restricted but was not painful and was managed conservatively.</p><p><b>CONCLUSION</b>The precontoured locking plates with lateral extension may be a good method to fix the fractures of the lateral end clavicle, which provide a stable fixation with good functional outcome with very few instances of stiffness and decreased range of motion of the shoulder with the hook plates and failure of fixation in screw and K-wire fixations. It may well be the answer to the fixation questions of the lateral clavicle fractures, although larger comparative studies between the surgical treatment methods are required to confirm the same.</p>

Finite element analysis on titanium elastic nail and reconstruction plate fixation for midshaft clavicular fractures / 医用生物力学

Objective To analyze the stress distribution and peak stress on midshaft clavicular fractures fixed by titanium elastic nail (TEN) or reconstruction plate, respectively. Methods CT data of the clavicle was adopted to reconstruct the intact clavicle model and the midshaft clavicular fracture models with the TEN and reconstruction plate fixation by using Mimics software. All the three dimensional finite element models were analyzed using Abaqus 6.9 software. The distal displacement, the peak stress and stress distribution on the distal clavicle under the axial load (250 N) and vertical load (250 N) were calculated for the three models. Results The axial displacement of the distal clavicle under the axial load showed TEN (0.23 mm)>intact clavicle (0.14 mm)>reconstruction plate (0.11 mm), respectively. While the vertical displacement of the distal clavicle under the vertical load was 5.12 mm for TEN, 3.71 mm for intact clavicle and 2.25 mm for reconstruction plate, respectively. But the peak stress of the clavicle under the axial load was 33.1 MPa for TEN, 18.7 MPa for reconstruction plate, and 15.5 MPa for intact clavicle model, respectively. And the peak stress under the vertical load was 146.3, 64.1, 56.1 MPa in the TEN, intact clavicle model, and reconstruction plate model, respectively. The stress distribution in TEN model under both kinds of loads was similar to that in intact clavicle model, while under the vertical load, the stress distribution in reconstruction plate model was clearly different with that in intact clavicle model. For the implants under the axial load, the peak stresses were 191.5, 52.3 MPa in the TEN model and reconstruction plate model, respectively, and the peak stress on implants under the vertical load was 1 248.0, 421.7 MPa in the TEN model and reconstruction plate model, respectively. Conclusions The TEN for treating midshaft clavicular fractures showed a stress distribution similar to the intact clavicle, with a higher peak stress and a higher peak implant stress at the fracture site. The reconstruction plate fixation for midshaft clavicular fractures was shown to be more stable, but with obvious stress shielding. Therefore, TEN is generally preferable for treating the simple displaced fractures of midshaft clavicle. However, the ipsilateral shoulder should avoid excessive exercise and weight bearing in the early postoperative period.

Comparison of results between conservative treatment and operative treatment for clavicle fractures in adults / 대한정형외과학회잡지

PURPOSE: The conservative treatment in the clavicular fractures is the gold standard. However, we found that there were some complications including angulation of clavicle and shortening of clavicular length, long-period immobilization, and nonunion in conservative treatment. This study was undertaken to evaluate union period, nonunion rate, and clinical results between conservative treatment and surgical treatment in clavicular fractures. MATERIALS AND METHODS: We evaluated 67 clavicular fractures in adults with conservative treatment (42 cases) and operative treatment (25 cases) from 1991 to 1996 and followed up for at least 1 year. RESULTS: Nonunion occurred in 4 cases (9.5%) in conservative treatment and 1 case (4.0%) in operative treatment (p>0.05) . The excellent results were 12 cases (28.6%) in conservative treatment and 12 cases (48.0%) in operative treatment (p>0.05) . CONCLUSION: We concluded that the early surgical treatment of displaced, low contact area of fracture segments of the clavicle fracture with internal fixation, even though not statistically significant, provides clinical results that are superior to those obtained with conservative care in view of early exercise of the shoulder joint, union period, rate of nonunion, correction of angular deformity and cosmetic problem. We thought that it leaves much room for consideration about the early surgical treatment for these fractures.
