High-energy trauma has increased significantly in the last decade, mostly in the lower limbs, in many cases requiring fasciotomy due to the subsequent compartment syndrome. In this context, its closure often leads to a delay in the patient's comprehensive treatment and the return to their activities and may lead to local infection, in addition to generating high costs. There are many options for the plastic surgeon to try to bring the edges together and reconstruct the extremities, such as flaps, grafts, vacuum dressings, and elastic sutures, in addition to expansion devices, sometimes with a combination of the above.
O trauma de grande energia vem aumentando de maneira expressiva na última década, em boa parte de membros inferiores, necessitando, em muitos casos, de fasciotomia devido à síndrome compartimental subsequente. Neste contexto muitas vezes seu fechamento acaba por levar a um retardo no tratamento integral do paciente, do retorno a suas atividades e podendo levar a infecção local, além de gerar altos custos. Há muitas opções ao cirurgião plástico para a tentativa de aproximação de bordos e reconstrução das extremidades, como retalhos, enxertos, curativo a vácuo e sutura elástica, além de dispositivos de expansão, sendo, às vezes, com combinação das anteriores. O método de fechamento apresentado através do alongamento progressivo da pele com fio de Kirschnner representa uma forma de baixo custo e facilmente reproduzível para lidar com este tipo de ferida.

All children achieved an anatomical reduction of the fracture postoperatively.No complications like fracture displacement, suture rupture, or infection were reported.All fractures healed completely at 3 months postoperatively.At the last follow-up, the Lysholm score and IKDC 2000 subjective score were (94.4±4.8) points and (93.8±5.6) points, respectively.The positive Lachman test was detected in 2 patients.No inhibition of proximal tibial epiphyseal growth was observed.Conclusions:Arthroscopic reduction with non-absorbable Krackow-" 8" suture and establishment of bone tunnels using a 2.0 mm perforated Kirschner wire for the treatment of tibial intercondylar ridge fractures in children has the advantages of simple surgical procedures, minimal invasiveness, which is an effective treatment method.
ABSTRACT
OBJECTIVE@#To explore the clinical effect of Kirschner wire intramedullary fixation in the treatment of both-bone forearm fractures in children of high altitude area.@*METHODS@#From August 2020 to December 2021, 19 children were treated with Kirschner wire intramedullary fixation including 11 males and 8 females, aged from 4 to 13 years old with an average of (8.16±2.71) years old. The course of disease was 1 to 10 days, with a mean of (4.11±2.51) d. First, close reduction was performed. If the reduction was unsuccessful, limited open reduction was performed, followed by Kirschner wire intramedullary fixation of the radius and ulna. The fracture healing was evaluated by X-ray after operation, and the curative effect was evaluated by Anderson forearm function score standard.@*RESULTS@#The wound healed well after operation, 2 cases had clinical manifestations of needle tail irritation after operation, and the symptoms disappeared after removing the internal fixation. The average follow-up time was(7.68±3.50) months (3 to 14 months). X-ray showed that all fracture healing in follow-up, Anderson forearm function score showed excellent in 16 cases, good in 2 cases and fair in 1 case at the final follow-up.@*CONCLUSION@#Children with fractures in plateau areas often have delayed medical treatment, lack of medical conditions and insufficient compliance. Based on these characteristics, Kirschner wire intramedullary fixation for the treatment of children's double forearm fractures has the advantages of small injury and rapid recovery. It is a kind of operation method that can be popularized.

Objective:To explore the clinical value of single-hole laparoscopic percutaneous extraperitoneal closure operation using a Kirschner wire assisted double-hook water-injection hernia needle in treating complicated pediatric oblique inguinal hernia.Methods:The clinical data of 366 children with oblique inguinal hernia treated in the Department of Urology Surgery, Children′s Hospital of Nanjing Medical University from December 2020 to October 2021 were retrospectively analyzed.According to the surgical methods, the children were divided into the ordinary crochet needle group and the Kirschner wire assisted group.Children treated by a single-port laparoscopic double hook water-injection hernia crochet needle (309 cases) were classified into the ordinary crochet needle group.Children treated by a single-port laparoscopic Kirschner wire assisted double hook water-injection hernia crochet needle (57 cases) were included in the Kirschner wire assisted group.The independent sample t-test and rank sum test was used to compare the relevant clinical indicators between the two groups. Results:Compared with the ordinary crochet needle group, children in the Kirschner wire assisted group were younger at surgery[(2.87±1.88) years vs.(4.91±2.39) years] and had larger hernia sacs [17 303.89(8 622.49, 37 295.42) mm 3vs.9 650.97(3 849.24, 17 539.51) mm 3]. The differences in the age at surgery and hernia sac volume were statistically significant ( t=-5.407, Z=-4.218; all P<0.001). There was no significant difference in body mass index between the 2 groups ( P>0.05). Taking hernias with sac volume >10 000 mm 3 as huge hernias, there were 70.18%(40/57 cases) and 47.25%(146/309 cases) of huge hernias in the Kirschner wire assisted group and the ordinary crochet needle group, respectively.The overall operation time of the Kirschner wire assisted group was significantly longer than that of the ordinary crochet needle group[(20(15, 20) min vs.15(15, 20) min] ( Z=-2.842, P<0.05). However, the operation time for huge oblique hernias with sac volume >10 000 mm 3 was not statistically significant between the 2 groups ( P>0.05). No recurrence in both groups was found during 6-16 months of follow-up. Conclusions:For complicated oblique inguinal hernia in children with a huge hernia or obvious retroperitoneal folds at the internal ring and heavy scar adhesion between the hernia sac and abdominal wall, the insertion of a Kirschner wire can help the hernia crochet needle to traverse the vas de-ferens and spermatic cord vessels smoothly.As a single port laparoscopic operation, the Kirschner wire assisted hernia crochet needle requires no addition of trocar holes and leaves only a small surgical scar.With good feasibility and safety, it is applicable for clinical popularization.
ABSTRACT
Objective To study the effect of interlocking intramedullary nail on fixing transverse olecranon fracture. Methods Nine pairs of fresh ulna specimens were collected and the transverse fracture model of olecranon was established. Kirschner wire tension band and interlocking intramedullary nail were used to repair the fracture. Cyclic dynamic tension loads with amplitude of 25 N, mean value of 45 N and frequency of 05 Hz were applied to the triceps tendon under simulated elbow flexion conditions of 30°, 45° and 60°, respectively. The fracture displacements of specimens within 300 cycles were recorded in three groups. ResultsAt 30° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.831±0.333) mm and (3.723±2.390) mm, respectively. At 45° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.167±0.374) mm and (2.455±0.609) mm, respectively. At 60° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.407±0.342) mm and (3.112±1.025) mm, respectively. The fracture displacement of interlocking intramedullary nail was smaller. Conclusions The mechanical properties of interlocking intramedullary nail are better than those of Kirschner wire tension band, and the interlocking intramedullary nail is more stable and firmer for fixing transverse olecranon fracture. Moreover, the interlocking intramedullary nail is installed with the operating tool, thus the operation is more accurate and faster, and the operation efficiency is greatly improved.
ABSTRACT
Objective:To evaluate the clinical efficacy of cannulated screws with sutures in the treatment of patellar transverse fractures.Methods:A retrospective analysis was performed of the data of 70 patients with patellar transverse fracture who had been admitted to Senior Department of Orthopedics, The Fourth Medical Center of Chinese PLA General Hospital from January 2017 to March 2021. According to the construction methods for the tension band, the patients were divided into 3 groups. In group A of 21 cases subjected to fixation with cannulated screws with sutures (Fiber-Tape), there were 8 males and 13 females with a median age of 55.0 (48.0, 65.0) years; in group B of 32 cases subjected to fixation with Kirschner wire tension band, there were 15 males and 17 females with a median age of 52.5 (41.5, 63.0) years; in group C of 17 cases subjected to fixation with Cable-Pin system, there were 5 males and 12 females with a median age of 55.0 (37.0, 65.0) years. The 3 groups were compared in terms of complications, secondary surgery (removal of internal fixation), operation time, intraoperative blood loss and knee function rated by the Lysholm and B?stman scores at the last follow-up.Results:There were no significant differences in the preoperative general data between the 3 groups, showing they were comparable ( P > 0.05). There was no significant difference in the operation time, intraoperative blood transfusion or follow-up time among the 3 groups ( P > 0.05). The incidence of soft tissue irritation [4.8% (1/21)] and the secondary operation rate [4.8% (1/21)] in group A were significantly lower than those in group B [43.8% (14/32) and 37.5% (12/32)] and group C [41.2% (7/17) and 35.3% (6/17)] ( P < 0.05), but there was no statistically significant difference between group B and group C ( P > 0.05). In groups A, B and C, respectively, the Lysholm knee score was 84.0 (69.0, 88.0), 89.0 (71.5, 95.0) and 82.0 (63.0, 90.0), and the B?stman knee score 26.0 (23.0, 28.0), 26.5 (24.0, 27.5) and 26.0 (22.0, 28.0), showing no significant difference ( P > 0.05). There was no significant difference either in the incidence of other complications among the 3 groups ( P > 0.05). Conclusion:In the treatment of patellar transverse fractures, compared with the Kirschner wire tension band and Cable-Pin system, cannulated screws with sutures (Fiber-Tape) may lead to a lower incidence of soft tissue irritation and a lower rate of secondary surgery, but no significant differences in operation time, intraoperative blood loss, other complications or postoperative functional scores.
ABSTRACT
@#Introduction: Scaphoid fractures are most often treated with a single headless compression screw. However, intercarpal Kirschner wire (K-wire) might be added to improve stability and fracture outcomes. This study will determine if there is a difference in treatment outcome (union rate and time to union) between scaphoid fracture fixations using a single headless compression screw with and without augmentation using a intracarpal intramedullary K-wire. Material and Methods: We conducted a retrospective review of patients who underwent surgery for isolated scaphoid fractures over a 15 years period from December 2000 to December 2015. Only patients who underwent open surgery with bone grafting were included. They were divided into a group treated with a single screw fixation, and another group treated with screw and K-wire fixations. Results: Forty-four (58.7%) patients had single screw fixation and 31 (41.3%) had screw augmented with K-wire fixation. The overall union rate was 88.0%, with an overall mean time to union of 5.3 months. There was no difference in union rate (p=0.84) and time to union (p=0.66) between the single screw group and combined screw and K-wire group. Univariate analysis found that older age (t=-2.11, p=0.04) had a significant effect on union rate. Regression model showed that age had a significant effect on months to union. Conclusion: In open fixation of scaphoid fractures with compression screw and bone grafting, union rate and time to union is comparable whether or not screw fixation was augmented with an intracarpal K-wire. There was no increased risk of complications associated with augmented screw. Age of patient affected time to union and union rate.
ABSTRACT
BACKGROUND: At present, the application of intelligent positioning devices such as orthopedic robots and computer navigation systems in closed reduction surgery for femoral neck fractures is gradually developed, and grassroots hospitals still need a cheap auxiliary positioning device. OBJECTIVE: To investigate the effect of a Kirschner wire positioning device for assisted localization in internal fixation of femoral neck fracture with cannulated screws. METHODS: Fifty-four cases of femoral neck fracture treated in Binzhou Medical University Hospital from February 2016 to March 2018 were retrospectively analyzed. The patients were allocated into the two groups, 28 patients who received traditional cannulated screws internal fixation were in the traditional group, and 26 patients who received assisted localization internal fixation with cannulated screws were in the assisted localization group. The angle, direction and distance of the Kirschner wire could be quantified and fine-tuned, assisted with accurate positioning, and the placement of the cannulated screws was guided. Clinical and imaging data were compared between two groups. RESULTS AND CONCLUSION: (1) All patients received surgery successfully. No intraoperative complications such as vascular or nerve injury occurred. Postoperative image showed good fracture reduction, cannulated screw distribution, angle and position. (2) The operation time in the assisted localization group (49.27±4.86) minutes was shorter than that in the traditional group (59.64±8.02) minutes (P 0.05). The excellent and good rate of Harris score in the assisted localization group was 89%. (4) No necrosis of femoral head occurred during the follow-up, and the rate of late necrosis should be followed up. (5) Our findings suggest that Kirschner wire positioning device can assist in quantitative positioning and guide the placement of cannulated screw in the internal fixation of femoral neck fracture. It can effectively improve the positioning efficiency, reduce the number of fluoroscopy, avoid repeatedly adjusting the penetration to damage femoral neck bone, and promote the recovery of patients.

Objective To investigate the clinical effect of minimally invasive Kirschner wire tension band internal fixation under arthroscopy in the treatment of patellar fracture.Methods From March 2016 to April 2018,ninety patients with patellar fracture admitted to the Department of Orthopedics,Lin Xi Hospital of Kailuan General Hospital were divided into minimally invasive group (58 cases) and control group (32 cases) according to different operative methods.The control group received traditional open reduction and Kirschner wire tension band internal fixation.Minimally invasive group received arthroscopic minimally invasive Kirschner wire tension band internal fixation.The operation status,joint function recovery and VAS scores were compared between the two groups.Results The amount of blood loss,hospitalization time and fracture healing time in minimally invasive group were significantly less than those in control group ((48.7 ±13.6) mlvs.(85.5±12.3) ml,t=12.7,P＜0.05;(12.5±2.8) d vs.(14.8±1.4) d,t=4.35,P＜0.05;(11.2± 1.3) weeks vs.(15.4± 2.2) weeks,t =11.40,P＜0.05).After 6 months of follow-up,the VAS score of the two groups decreased with the time (the VAS score of the minimally invasive group decreased from (7.2±1.1) points preoperatively to (0.9±0.2) points at 6 months postoperatively,and that of the control group decreased from (7.3±1.2) points preoperatively to (1.1±0.3) at 6 months postoperatively).There was a significant difference between the two groups (F group =77.87,P＜0.05).The VAS score of both groups decreased with time (Ft ime=263.47,P＜0.05).The decrease of VAS score in the minimally invasive group was significantly larger than that in the control group (F interaction =28.63,P＜0.05).Conclusion Arthroscopic minimally invasive Kirschner wire tension band internal fixation for patellar fracture has better clinical effect and less trauma.
ABSTRACT
Objective: To explore the feasibility and effectiveness of maintaining the reduction of unstable intertrochanteric fractures by Kirschner wire-fixation-cortical bone technique. Methods: Forty patients with intertrochanteric fracture [AO/Orthopaedic Trauma Association (AO/OTA) type 31-A2.2] admitted between May 2015 and January 2017 and requiring closed reduction and proximal femoral nail antirotation (PFNA) were randomly divided into trial group (intraoperative Kirschner wire-fixation-cortical bone technique group, 20 cases) and control group (conventional treatment group, 20 cases). There was no significant difference in general data of gender, age, side, body mass index, cause of injury, time from injury to operation between the two groups ( P>0.05). The operation time, intraoperative blood loss, and intraoperative fluoroscopy times of the two groups were recorded; the reduction quality of fracture was observed according to the corresponding relationship between medial and anterior cortex (positive, neutral, and negative support) of intraoperative fluoroscopy proposed by ZHANG Shimin, and the stability of internal fixation and fracture healing were observed; Harris score was used to evaluate the recovery of hip function at 12 months after operation. Results: In the trial group, 6 cases (30%) had 2 Kirschner wires implanted less than 4 times, 7 cases (35%) had 5-8 times, and 7 cases (35%) had 9 times or more. There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05), but the blood transfusion volume and intraoperative fluoroscopy times in the trial group were significantly less than those in the control group ( P<0.05). Both groups were followed up 13-21 months, with an average of 17 months. There was no complications such as wound infection, deep venous thrombosis of lower extremities, refracture, and internal fixation-related complications. The quality of intraoperative reduction in the trial group was significantly better than that in the control group ( Z=-2.794, P=0.024). The Harris score of the trial group was significantly better than that of the control group at 12 months after operation ( t=2.98, P=0.01). Conclusion: The use of Kirschner wire-fixation-cortical bone technique during intertrochanteric fracture closed reduction and PFNA internal fixation surgery can effectively maintain the reduction effect, reduce the number of fluoroscopy, improve the reduction quality, reduce allogeneic blood input, obtain better hip function, and do not increase the operation time and intraoperative blood loss.
ABSTRACT
Objective To evaluate K-wire leverage reduction and fixation via the triceps tendon for irreducible supracondylar humeral fractures of Gartland types Ⅱ& Ⅲ. Methods From June 2014 to March 2016, 31 children with irreducible supracondylar humeral fracture were treated operatively in our hospital. They were 23 boys and 8 girls, aged from 4 to 11 years ( average, 6. 3 years ) , involving 19 left and 12 right arms. Their clinical manifestations included elbow swelling at the affected arm, obvious tenderness, and limited movement of the elbow. The reduction was conducted under the guidance of C-arm roentgenography by inserting a piece of 3. 0 mm K-wire into the fracture ends via the posterior triceps tendon, inserting 2 pieces of 1. 5 or 2. 0 mm K-wire from the distal lateral humerus to the proximal through the opposite cortical bone, and inserting a piece of 1. 5 or 2. 0 mm K-wire into the opposite cortical bone through the ulnar aspect of the distal humerus. Results The operation time for the 31 patients ranged from 28 to 42 minutes ( 33 minutes on average ) . They were followed up for 6 to 18 months ( 12. 3 months on average ) . All fractures united after 4 to 6 weeks ( 4. 6 weeks on average ) . At the final follow-ups, the lengths of the affected and healthy arms were re-spectively 66. 4 ± 2. 7 cm and 66. 4 ± 2. 9 cm, showing no significant difference ( P> 0. 05 ) . The therapeutic outcomes by the Flynn criteria for the elbow function were rated at the final follow-up as excellent in 26 cases, as good in 4 and as fair in one, yielding an excellent to good rate of 96. 8％. Pin tract infection occurred in 2 patients, but no deep infection or osteomyelitis was observed during follow-ups. Conclusion K-wire leverage reduction and fixation via the triceps is an effective and simple treatment for irreducible supracondylar humeral fractures of Gartland types Ⅱ& Ⅲ.

ABSTRACT
Objective: To summarize the effectiveness of mini locking plate combined with Kirschner wire in treatment of comminuted Jones fracture. Methods: Between January 2011 and October 2016, 25 cases with comminuted Jones fracture were treated with mini locking plate combined with Kirschner wire. There were 9 males and 16 females with an average age of 31.4 years (range, 16-66 years). The fractures located on the left side in 11 cases and on the right side in 14 cases. The causes of injury included spraining in 21 cases, falling down in 3 cases, and bruise in 1 case. The bone fragment of all cases was more than 3 pieces. The fracture line was mostly Y-shape or T-shape. Twelve of them were combined with other fractures. The time from injury to operation was 1-9 days (mean, 5 days). The mini locking plate and Kirschner wire were removed at 9-12 months postoperatively. At 12 months postoperatively, the pain was evaluated by the visual analogue scale (VAS) score, and the function by the American Orthopaedic Foot & Ankle Society (AOFAS) score. Results: All incisions healed by first intention. All cases were followed up 12-36 months with an average of 21.7 months. Fracture union was observed in all patients without complications such as nonunion, delayed union, and malunion. The fracture union time was 8-12 weeks (mean, 9.4 weeks). At 12 months postoperatively, the VAS score was 1.15±0.87; the AOFAS score was 89.45±6.24, and the results were excellent in 14 cases, good in 9 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 92%. Conclusion: The procedure of mini locking plate combined with Kirschner wire for comminuted Jones fracture has such advantages as convenient operation, more rigid fixation, high rate of fracture healing, and good functional recovery in foot.
