ABSTRACT

OBJECTIVE@#To review the advancement made in the understanding of valgus impacted proximal humeral fracture (PHF).@*METHODS@#The domestic and foreign literature about the valgus impacted PHF was extensively reviewed and the definition, classification, pathological features, and treatment of valgus impacted PHFs were summarized.@*RESULTS@#PHF with a neck shaft angle ≥160° is recognized as a valgus impacted PHF characterized by the preservation of the medial epiphyseal region of the humeral head, which contributes to maintenance of the medial periosteum's integrity after fracture and reduces the occurrence of avascular necrosis. Therefore, the valgus impacted PHF has a better prognosis when compared to other complex PHFs. The Neer classification designates it as a three- or four-part fracture, while the AO/Association for the Study of Internal Fixation (AO/ASIF) categorizes it as type C (C1.1). In the management of the valgus impacted PHF, the selection between conservative and surgical approaches is contingent upon the patient's age and the extent of fracture displacement. While conservative treatment offers the advantage of being non-invasive, it is accompanied by limitations such as the inability to achieve anatomical reduction and the potential for multiple complications. Surgical treatment includes open reduction combined with steel wire or locking plate and/or non-absorbable suture, transosseous suture technology, and shoulder replacement. Surgeons must adopt personalized treatment strategies for each patient with a valgus impacted PHF. Minimally invasive surgery helps to preserve blood supply to the humeral head, mitigate the likelihood of avascular necrosis, and reduce postoperative complications of bone and soft tissue. For elderly patients with severe comminuted and displaced fractures, osteoporosis, and unsuitable internal fixation, shoulder joint replacement is the best treatment option.@*CONCLUSION@#Currently, there has been some advancement in the classification, vascular supply, and management of valgus impacted PHF. Nevertheless, further research is imperative to assess the clinical safety, biomechanical stability, and indication of minimally invasive technology.

ABSTRACT

Abstract Objective To compare the use of cannulated screws and smooth Kirschner wires in terms of reducing the presence of exuberant callus and complications in pediatric displaced fractures of the lateral humeral condyle. Methods An analytical cross-sectional study of consecutive cases was conducted from May to October 2021 with 30 children with displaced external humeral condyle fractures. The functional results regarding pain and range of motion were stratified using the Dhillon grading system. Results A total of 19 patients underwent Kirschner wire fixation, and 11 underwent cannulated screw fixation. Closed fixation was performed in 14 cases (47%), and open fixation, in 16 (53%). Of the cases included, there was no loss to follow-up. Te sample was composed of 21 (70%) male patients, and the age ranged from 5 to 15 years, with a mean of 6.96 years. The most frequent cause of fracture was fall from height (50%), which was related to greater displacement on baseline radiographs. Complications that were not related to the reduction approach or the implant used were observed in 12 (40%) cases. Conclusion The present study shows no benefits in relation to the use of smooth pins or cannulated screws to reduce the presence of exuberant callus in the consolidation of the fracture. We see that the complications that arise are related to the severity of the injury, and benefits cannot be identified in the choice of one implant over another. We could see that the Weiss classification helps to define the behavior in favor of open or closed reduction without interfering in kindness of the smooth pin or the cannulated screw for fracture fixation.


Resumo Objetivo Comparar o uso de parafusos canulados e de fios de Kirschner lisos em termos da redução da presença de calo exuberante e de complicações em fraturas pediátricas deslocadas do côndilo lateral do úmero. Métodos Um estudo analítico transversal de casos consecutivos foi realizado de maio a outubro de 2021 com 30 crianças com fraturas deslocadas de côndilo umeral externo. Os resultados funcionais para dor e amplitude de movimento foram estratificados utilizando o sistema de classificação Dhillon. Resultados Ao todo, 19 pacientes foram submetidos à fixação de fio Kirschner, e 11 à fixação de parafusos canulados. A fixação realizada foi fechada em 14 casos (47%) e aberta em 16 (53%). Dos casos incluídos, não houve perda no acompanhamento. A amostra continha 21 (70%) pacientes do sexo masculino, e a idade variou de 5 a 15 anos, com média de 6,96 anos. A causa mais frequente de fratura foi queda de altura (50%), e esteve relacionada ao maior deslocamento nas radiografias da linha de base. Complicações que não estavam relacionadas à abordagem de redução ou ao implante utilizado foram observadas em 12 (40%) casos. Conclusão Este estudo não mostra benefícios em relação ao uso de pinos lisos ou de parafusos canulados para reduzir a presença de calo exuberante na consolidação da fratura. Vemos que as complicações que surgem estão relacionadas à gravidade da lesão, e não é possível identificar benefícios na escolha de um implante ou outro. Pudemos ver que a classificação de Weiss ajuda a definir o comportamento em favor da redução aberta ou fechada sem dar preferência ao pino liso ou ao parafuso canulado para a fixação da fratura.

ABSTRACT

OBJECTIVE@#To investigate the short-term effectiveness of ultrasound-guided closed reduction by Kirschner wire provocation technique in the treatment of Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents.@*METHODS@#Between May 2019 and May 2022, 41 patients with Salter Harris types Ⅰ and Ⅱ distal tibial epiphyseal fractures were admitted, all of whom had periosteal entrapment on preoperative MRI, and 38 cases (92.7%) were confirmed to have periosteal entrapment by intraoperative ultrasound. There were 24 males and 14 females, the age ranged from 6.8 to 15.7 years, with an average of 10.7 years; and there were 20 cases of Salter Harris type Ⅰ and 18 cases of type Ⅱ. The time from injury to operation was 22-76 hours, with an average of 28.4 hours. The preoperative imaging examination showed excellent alignment in 4 cases, good in 20 cases, and poor in 14 cases. The ultrasound guided Kirschner wire provocation technique for closed reduction and percutaneous Kirschner wire internal fixation were performed. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Anteroposterior and lateral X-ray films of the affected ankle joint were taken before operation, at 3 months after operation, and at last follow-up to observe the healing of the fracture, and anteroposterior X-ray films of the whole length of both lower limbs were taken to evaluate the alignment of the force lines of the affected limbs. The range of motion (ROM), visual analogue scale (VAS) score, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used to evaluate ankle function. The mechanical lateral distal tibia angle (mLDTA) and the anatomic anterior distal tibia angle (aADTA) were measured.@*RESULTS@#The operation time ranged from 17 to 52 minutes, with an average of 22.6 minutes, and the intraoperative fluoroscopy frequency ranged from 3 to 11 times, with an average of 4.2 times. X-ray examination during operation and at 2 days after operation showed that anatomical reduction was achieved. All patients were followed up 10-24 months, with an average of 16.4 months. All fractures healed in 6.1-7.2 weeks, with an average of 6.3 weeks; no fracture displacement occurred, and the patients recovered to their pre-injury level of motion at 6 months after operation. Needle tail irritation occurred in 2 cases at 4 weeks after operation, and they recovered after symptomatic treatment. During the follow-up, there was no serious complication such as incision deep infection, bone nonunion, delayed union, and malunion. At last follow-up, the patients' alignment were all excellent, and the difference was significant when compared with preoperative one ( Z=-7.471, P<0.001). The VAS score, AOFAS ankle-hindfoot score, dorsiflexion-plantar flexion ROM, varus-valgus ROM, mLDTA, and aADTA significantly improved at 3 months after operation and last follow-up when compared with preoperative ones ( P<0.05).@*CONCLUSION@#Ultrasound-guided closed reduction by Kirschner wire provocation technique for treating Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents is minimally invasive and safe.

ABSTRACT

OBJECTIVE@#To summarize the effectiveness of Kirschner wire buckling combined with bone fixation in the treatment of metacarpal avulsion fracture.@*METHODS@#The clinical data of 35 patients of metacarpal avulsion fracture admitted between March 2017 and June 2022 were retrospectively analyzed. There were 22 males and 13 females; the age ranged from 20 to 55 years, with an average of 31.6 years. There were 17 cases of the second metacarpal avulsion fracture, 6 cases of the fourth metacarpal avulsion fracture, and 12 cases of the fifth metacarpal avulsion fracture. The causes of injury included 21 cases of strangulation, 8 cases of sprain, and 6 cases of sports injury. X-ray film examination showed that the size of the avulsion fracture of metacarpal bone ranged from 0.30 cm×0.20 cm to 0.55 cm×0.45 cm. The total active motion (TAM) of the injured finger before operation was (154.00±17.38)°. The time from injury to operation was 3-10 days, with an average of 5.8 days. Follow-up regularly after operation, X-ray film and CT examination were performed to evaluate fracture healing and TAM of injured finger was measured. The finger function was evaluated by the trial standard of upper limb function evaluation of Hand Surgery Society of Chinese Medical Association.@*RESULTS@#All the incisions healed by first intention. All 35 patients were followed up 9-36 months, with an average of 28 months. All metacarpal avulsion fractures achieved bony healing, and the healing time was 4-6 weeks, with an average of 4.8 weeks. The metacarpophalangeal joint of the patient was stable, without stiffness, and the flexion and extension activities were good. At last follow-up, the TAM of the injured finger reached (261.88±6.23)°, which was significantly different from that before operation ( t=-35.351, P<0.001). The finger function was evaluated according to the trial standard of upper limb function evaluation of the Society of Hand Surgery of Chinese Medical Association, and 33 cases were excellent and 2 cases were good, with an excellent and good rate of 100%.@*CONCLUSION@#The treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation has the advantages of less trauma, firm fixation, and less interference to the soft tissue around metacarpophalangeal joints, which is a good alternative method for the metacarpal avulsion fracture.

ABSTRACT

OBJECTIVE@#To explore the effectiveness of arthroscopic treatment of scaphoid fracture nonunion with bone graft and Kirschner wire combined with screw fixation.@*METHODS@#The clinical data of 14 patients with scaphoid fracture nonunion who met the selection criteria between February 2021 and September 2022 were retrospectively analyzed. There were 13 males and 1 female with an average age of 32 years ranging from 17 to 54 years. The time from injury to operation ranged from 6 to 15 months, with an average of 9.6 months. According to the Slade-Geissler classification of scaphoid fracture nonunion, there were 3 cases of grade Ⅲ, 8 cases of grade Ⅳ, and 3 cases of grade Ⅴ. The preoperative visual analogue scale (VAS) score was 5.9±1.0, and the modified Mayo wrist score was 53.2±9.1. There were 2 cases of scaphoid nonunion advanced collapse, both of which were stage Ⅰ. All patients were treated with arthroscopic bone graft and Kirschner wire combined with screw fixation, and the fracture healing was observed by X-ray film monthly after operation, and the effectiveness was evaluated by VAS score and modified Mayo wrist score before and after operation.@*RESULTS@#All patients were followed up 6-14 months, with an average of 8.4 months. All fractures healed in 4-8 months, with an average of 6.3 months. The postoperative pain symptoms and wrist function of the patients significantly improved when compared with those before operation, and the VAS score at last follow-up was 2.4±1.3, and the modified Mayo wrist score was 87.1±6.7, which were significantly different from those before operation ( t=12.851, P<0.001; t=-14.410, P<0.001). According to the modified Mayo wrist evaluation, 9 cases were excellent, 3 cases were good, and 2 cases were fair.@*CONCLUSION@#Arthroscopic bone graft and Kirschner wire combined with screw fixation is an effective surgical method for the treatment of scaphoid fracture nonunion.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures.@*METHODS@#The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up.@*RESULTS@#All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5).@*CONCLUSION@#Kirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of medial and lateral column periosteal hinge reconstruction using Kirschner wire in the closed reduction of multi-directional unstable humeral supracondylar fractures in children.@*METHODS@#A clinical data of 43 children with multi-direction unstable humeral supracondylar fractures, who met the selection criteria and were admitted between August 2020 and August 2022, was retrospectively analyzed. Twenty-one cases of fractures were treated wuth closed reduction after medial and lateral column periosteal hinge reconstruction using Kirschner wire and percutaneous Kirschner wires fixation (study group), while 22 cases of fractures were treated by traditional closed reduction technique and percutaneous Kirschner wire fixation (control group). There was no significant difference in gender, age, cause of injury, fracture side, and interval from injury to operation between the two groups ( P>0.05). The operation time, intraoperative fluoroscopy times, the number of children who were changed to open reduction after closed reduction failure, fracture healing time, complications within 2 months after operation, and the Flynn score of elbow joint function at last follow-up were compared between the two groups.@*RESULTS@#All the fractures in the study group were successfully closed reduction, and 4 cases in the control group were changed to open reduction and completed the operation, the difference between the two groups was significant ( P=0.040). The operation time and intraoperative fluoroscopy times of the study group were significantly less than those of the control group ( P<0.05). All children in both groups were followed up 6-18 months with an average of 9.0 months in the study group and 9.8 months in the control group. Imaging review showed that the fractures of both groups healed, and the difference in the healing time between the two groups was not significant ( P=0.373). According to Flynn score at last follow-up, the excellent and good rate of elbow joint function was 95.2% (20/21) in the study group and 86.4% (19/22) in the control group, with no significant difference ( P=0.317). There was no complication such as infection or irritation at the end of Kirchner wire within 2 months after operation.@*CONCLUSION@#For children with multi-directional unstable humeral supracondylar fractures, the use of Kirschner wires to reconstruct the medial and lateral column periosteal hinge to assist in closed reduction has the advantages of shortening operation time, reducing intraoperative fluoroscopy times, and effectively reducing the incidence of open reduction, and can achieve similar postoperative elbow joint function when compared with traditional closed reduction technique.

ABSTRACT

OBJECTIVE@#To compare the effectiveness of ultrasound- and arthrography-assisted Kirschner wire fixation in the treatment of Jakob type Ⅱ lateral condylar humerus fracture (LCHF) in children.@*METHODS@#A clinical data of 101 children with Jakob type Ⅱ LCHF, who met the selection criteria and were admitted between April 2021 and April 2022, was retrospectively analyzed. Of them, 47 cases were treated with ultrasound-assisted Kirschner wire fixation (group A), and 54 cases with arthrography-assisted surgery (group B). There was no significant difference in gender, age, cause of injury, fracture side, and disease duration between groups (P>0.05). Intraoperative fluoroscopy times, operation time, and hospital stay, Flynn elbow joint function score, and postoperative complications were recorded and compared between groups. X-ray examination was performed to observe the healing of fracture, and measure the carrying angle and the shaft-condylar angle (SCA).@*RESULTS@#The success rate of closed reduction was significantly higher in group A than in group B (P<0.05), and the intraoperative fluoroscopy times was significantly less in group A than in group B (P<0.05). There was no significant difference in operation time and hospital stay between groups (P>0.05). All children in both groups were followed up 12-18 months, with an average of 13.6 months. X-ray reexamination showed that the fractures of both groups healed, and the difference in healing time was not significant (P>0.05). At last follow-up, there was no significant difference in carrying angle and SCA between unaffected side and affected side in both groups and between groups A and B in affected side (P>0.05). There was no significant difference in Flynn elbow joint function score between groups (P>0.05). There were 18 cases of lateral spurs formation in group A, 1 case of pinning infection and 26 cases of lateral spurs formation in group B, and there was no significant difference in the incidence of the above complications (P>0.05).@*CONCLUSION@#Compared with the arthrography, the ultrasound-assisted Kirschner wire fixation in the treatment of Jakob type Ⅱ LCHF in children can avoid the open reduction and decrease the number of intraoperative fluoroscopy, and obtain the good effectiveness.

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.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of double pulley combined with suture bridge in the treatment of comminuted fracture of the lower pole of the patella.@*METHODS@#From January 2018 to June 2020, 15 patients with comminuted fracture of the lower pole of the patella were treated with double pulley and suture bridge technology, including 9 males and 6 females, aged 28 to 68 years old with an average of (42.4±9.6) years old. All patients had obvious knee joint pain and limited movement after injury. All knee joints were examined by X-ray and CT, which confirmed that they were all comminuted fractures at the lower level of the patella. After operation, X-ray films of the knee joint were taken regularly to understand the fracture healing, the Insall Salvati index was measure, the range of motion of the joint was recorded, and the function of the knee joint was evaluateed by the Bostman scoring system.@*RESULTS@#All the 15 patients were followed up for 7 to 24 months with an average of (11.4±4.2) months, and there was no obvious anterior knee pain. At the last follow-up, the knee joint range of motion of the affected limb was 105° to 140° with an average of (128.5±12.8) °, and the Insall Salvati index was 0.79 to 1.12 with an average of (0.92±0.18). The X-ray film showed that the patella was bone healing, and no anchor fell off, broken, or displaced fracture block was found. Bostman patellar fracture function score was 27.85±2.06, 13 cases were excellent, 2 cases were good.@*CONCLUSION@#Double pulley technique combined with suture bridge technique is reliable for reduction and fixation of comminuted fracture of the lower pole of patella, and patients can start functional exercise early after operation.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of micro steel plate and Kirschner needle oblique and transverse internal fixation of adjacent metacarpal bone in the treatment of metacarpal diaphyseal oblique fracture.@*METHODS@#Fifty-nine patients with metacarpal diaphyseal oblique fractures admitted between January 2018 and September 2021 were selected as the study subjects and divided into the observation group (29 cases) and the control group (30 cases) based on different internal fixation methods. The observation group was treated with Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones, while the control group was treated with micro steel plate internal fixation. Postoperative complications, operation time, incision length, fracture healing time, treatment cost, and metacarpophalangeal function were compared between the two groups.@*RESULTS@#No incision or Kirschner wire infections occurred in the 59 patients, except for one in the observation group. No fixation loosening, rupture, or loss of fracture reduction occurred in any of the patients. The operation time and incision length in the observation group were (20.5±4.2) min and (1.6±0.2) cm, respectively, which were significantly shorter than those in the control group (30.8±5.6) min and (4.3±0.8) cm (P<0.05). The treatment cost and fracture healing time in the observation group were (3 804.5±300.8) yuan and (7.2±1.1) weeks, respectively, which were significantly lower than those in the control group (9 906.9±860.6) yuan and (9.3±1.7) weeks (P<0.05). The excellent and good rate of metacarpophalangeal joint function in the observation group was significantly higher than that in the control group at 1, 2, and 3 months after operation (P<0.05), but there was no significant difference between the two groups at 6 months after operation (P>0.05).@*CONCLUSION@#Micro steel plate internal fixation and Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones are both viable surgical methods for treating metacarpal diaphyseal oblique fractures. However, the latter has the advantages of causing less surgical trauma, shorter operation time, better fracture healing, lower cost of fixation materials, and no need for secondary incision and removal of internal fixation.

ABSTRACT

OBJECTIVE@#To investigate effectiveness of suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling in the treatment of patellar inferior pole fractures.@*METHODS@#A clinical data of 37 patients with unilateral patellar inferior pole fracture who met the selection criteria between June 2017 and June 2021 was retrospectively analyzed. Among them, 17 cases were treated with the suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling (group A), and 20 cases were treated with the traditional Kirschner wire tension band technique (group B). There was no significant difference in terms of gender, age, body mass index, fracture side, combined medical disease, and preoperative hemoglobin between the two groups ( P>0.05). Operation time, intraoperative blood loss, postoperative complications, fracture healing time, knee range of motion, and knee function Bostman score (range of motion, pain, daily work, muscle atrophy, walking aids, knee effusion, soft leg, and stair climbing) and grading were recorded in both groups at last follow-up.@*RESULTS@#There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). All incisions healed by first intention. All patients were followed up 1-2 years, with an average of 1.7 years. X-ray films reexamination showed that all fractures in group A healed, while 2 cases in group B did not heal. There was no significant difference in bone healing time between the two groups ( P>0.05). At last follow-up, the knee range of motion, the range of motion score of Bostman score, total score and effectiveness grading in group A were significantly better than those in group B ( P<0.05). There was no significant difference in the other items of Bostman scores between the two groups ( P>0.05). During follow-up, 2 cases of internal fixation failure and 1 case of internal fixator irritation occurred in group B, and no complication related to internal fixation occurred in group A. The occurrence of complications was significantly lower in group A than in group B ( P<0.05).@*CONCLUSION@#Compared with the traditional Kirschner wire tension band technique, the suture anchor combined with Nice knot strapping via longitudinal patellar drilling for the patellar inferior pole fractures has the advantages of simple operation, reliable fixation, early flexion and extension activity, and better functional recovery of knee joint.

ABSTRACT

OBJECTIVE@#To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children.@*METHODS@#Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria.@*RESULTS@#All incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up ( P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up ( P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up ( P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%.@*CONCLUSION@#The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.

ABSTRACT

OBJECTIVE@#To investigate the feasibility and effectiveness of absorbable anchor combined with Kirschner wire fixation in the reconstruction of extension function of old mallet finger.@*METHODS@#Between January 2020 and January 2022, 23 cases of old mallet fingers were treated. There were 17 males and 6 females with an average age of 42 years (range, 18-70 years). The cause of injury included sports impact injury in 12 cases, sprain in 9 cases, and previous cut injury in 2 cases. The affected finger included index finger in 4 cases, middle finger in 5 cases, ring finger in 9 cases, and little finger in 5 cases. There were 18 patients of tendinous mallet fingers (Doyle type Ⅰ), 5 patients were only small bone fragments avulsion (Wehbe type ⅠA). The time from injury to operation was 45-120 days, with an average of 67 days. The patients were treated with Kirschner wire to fix the distal interphalangeal joint in a mild back extension position after joint release. The insertion of extensor tendon was reconstructed and fixed with absorbable anchors. After 6 weeks, the Kirschner wire was removed, and the patients started joint flexion and extension training.@*RESULTS@#The postoperative follow-up ranged from 4 to 24 months (mean, 9 months). The wounds healed by first intention without complications such as skin necrosis, wound infection, and nail deformity. The distal interphalangeal joint was not stiff, the joint space was good, and there was no complication such as pain and osteoarthritis. At last follow-up, according to Crawford function evaluation standard, 12 cases were excellent, 9 cases were good, 2 cases were fair, and the good and excellent rate was 91.3%.@*CONCLUSION@#Absorbable anchor combined with Kirschner wire fixation can be used to reconstruct the extension function of old mallet finger, which has the advantages of simple operation and less complications.

ABSTRACT

INTRODUCCIÓN Las fracturas conminutas del polo distal de la patela representan un desafío para el cirujano de rodilla, pues no existe un tratamiento estándar que permita una rehabilitación acelerada. Recientemente se han descrito la osteosíntesis y la reinserción del polo distal utilizando asas de alambre verticales. MATERIALES Y MÉTODOS Presentamos dos casos de fractura conminuta del polo distal de la patela resueltos con asas de alambre verticales y modificaciones de esta técnica. RESULTADOS Se realizó osteosíntesis del polo distal de la patela, y se logró una reducción radiográfica satisfactoria, lo que permitió una rehabilitación acelerada, con un rango de movilidad progresivo a tolerancia desde el día siguiente tras la cirugía. Los pacientes lograron recuperar el rango de movimiento completo a los dos y tres meses de operados, evolucionaron satisfactoriamente, sin complicaciones relacionadas a esta técnica y sus variaciones, y recibieron el alta médica tras cuatro meses de la reducción y osteosíntesis. DISCUSIÓN Las técnicas tradicionales para el manejo de fracturas del polo distal implican consideraciones especiales en la rehabilitación y complicaciones asociadas. Se utilizó la técnica de asas de alambres verticales en dos pacientes: en uno de ellos, el procedimiento fue complementado con sutura tipo Krackow; y, en el otro, con una placa para minifragmentos, lo que permitió una rehabilitación acelerada y retorno precoz a sus actividades laborales. CONCLUSIÓN El uso de asas de alambre vertical aparece como una técnica segura, que permite una rehabilitación acelerada y un reintegro laboral precoz.


INTRODUCTION Comminuted fractures of the distal pole of the patella represent a challenge for the knee surgeon, as there is no standard treatment that enables accelerated rehabilitation. Osteosynthesis and reattachment of the distal pole using vertical wire loops has recently been described. MATERIALS AND METHODS We herein present two cases of omminuted fracture of the distal pole of the patella resolved with vertical wire loops and modifications of this technique. RESULTS Osteosynthesis of the distal pole of the patella was performed, achieving a satisfactory radiographic reduction and enabling accelerated rehabilitation, with a progressive range of motion the day after the surgery. The patients achieved full range of motion two and three months after surgery. They progressed satisfactorily, without complications related to this technique and its variations, and were discharged four months after the reduction and osteosynthesis. DISCUSSION The traditional techniques for the management of distal pole fractures involve special considerations regarding rehabilitation and associated complications. The vertical wire loop technique was used in two patients: in one of them, it was supplemented with a Krackow suture; and, in the other, with a mini-fragment plate, which enabled accelerated rehabilitation and early return to work. CONCLUSION The use of vertical wire loops appears to be a safe technique, which enables accelerated rehabilitation and early return to work.

ABSTRACT

Introducción: El objetivo de este estudio retrospectivo fue evaluar si la reducción abierta con cerclaje de alambre afectó la consolidación, la tasa de complicaciones y de reoperaciones en pacientes con fracturas subtrocantéricas de cadera, tratadas con clavos cefalomedulares. materiales y métodos:Se evaluó a todos los pacientes operados consecutivamente entre enero de 2010 y diciembre de 2017. Se comparó a los tratados con cerclaje (Grupo A) o sin cerclaje (Grupo B) de alambre en términos de tipo de fractura, estancia hospitalaria, tiempo quirúrgico, necesidad de transfusiones, calidad de la reducción, consolidación y complicaciones (infección, seudoartrosis, reoperaciones). Resultados:Se incluyó a 58 pacientes. El grupo A estaba conformado por 20 pacientes y el grupo B, por 38. El tipo de fractura más frecuente fue 3A (p = 0,0004). La estancia hospitalaria fue similar (9.0 vs. 10.6 días; p = 0,81), el tiempo quirúrgico y la necesidad de transfusiones fue mayor en el grupo A (p<0,0001 y p = 0,58, respectivamente). La tasa de consolidación fue similar en ambos grupos (90 vs. 92,1%, respectivamente; p = 0,09). Los desejes se observaron solo en el grupo tratado sin lazadas (5-13,5%; p = 0,01). Las tasas de complicaciones (15 vs. 18,4%) y de reopera-ciones (15 vs. 15,8%) fueron similares (p = 0,99). Conclusiones: El uso de lazadas de alambre en fracturas subtrocantéricas de cadera tratadas con clavos cefalomedulares generó un aumento significativo del tiempo quirúrgico, y disminuyó significativamente la incidencia de desejes. La incidencia de reoperaciones fue menor, aunque no significativamente. Nivel de Evidencia: III


Background: The aim of this retrospective study was to assess whether open reduction with cerclage wire affected the union and/or complication rate in subtrochanteric hip fractures treated with cephalomedullary nails. materials and methods: We analyzed all patients who had undergone surgery in our center between January 2010 and December 2017. We comparatively analyzed those treated with (Group A) and without (Group B) cerclage wire in terms of fracture type, hospital stay, surgical time, blood transfusions, malalignment, union, and complications (infection rates, non-union, and reoperations). Results: Fifty-eight patients were included. Group A consisted of 20 patients and Group B of 38. The most frequent type of fracture was 3A (p 0.0004). The mean hospital stay was similar (9 vs 10.6 days p 0.81), the surgical time and transfusions were higher in group A (p<0.0001 and p 0.58 respectively). The union rate was similar (90 vs 92.1%; p 0.09, respectively). Malalignment was only observed in group B (5 - 13.5%; p 0.01). The complication (15 vs 18.4%) and reoperation (15 vs 15.8%) rates were similar (p 0.99). Conclusions: The use of cerclage wire in subtrochanteric hip fractures treated with cephalomedullary nails generated a significant increase in surgical time and a lower rate of malalignment. It allowed a lower rate of re-operation, although it was not significant. Level of Evidence: III

ABSTRACT

OBJECTIVE@#To explore feasibility of closed reduction technique under monitoring of C-arm and three screws in the fixation of abduction and insertion femoral neck fracture.@*METHODS@#Seventeen patients with abduction and insertion femoral neck fracture operated from January 2014 to December 2019 were analyzed retrospectively, including 10 males and 7 females, aged from 21 to 59(42.09±7.30) years old. According to preoperative X-ray and CT data, angle of retroversion and abduction displacement of femoral head were determined. Two 2 mm diameter Kirschner wires crossed and gently knocked into the bone of the acetabular roof from outside and front of femoral head. The proximal fracture segment was fixed on the acetabulum. Under the monitoring of C-arm, lower limb (distal fracture segment) was gradually rotated inward and retracted against direction of fracture displacement, three cannulated screws were used for internal fixation after anatomical reduction of the distal fracture end and the proximal fracture end. Garden index was evaluated, postoperative complications were observed, and Harris functional score was performed.@*RESULTS@#All 17 cases of femoral neck fracture with abduction and insertion were successfully completed closed reduction and internal fixation. The operation time was 36 to 68(43.87±7.63) min and intraoperative bleeding was 15 to 50(28.36±5.93) ml. The quality of fracture reduction was evaluated by garden index during operation. There were 12 cases of anatomical reduction, 5 cases of acceptable reduction, and no cases of unsuccessful reduction were changed to open reduction. 17 cases were followed up for 3 to 41(27.5±8.4) months. There were no complications such as femoral head necrosis, fracture nonunion, hip impingement and femoral neck shortening. MR examination showed no femoral head necrosis and articular cartilage injury. Two years after operation, Harris score of hip joint was excellent in 13 cases and good in 4 cases.@*CONCLUSION@#Closed reduction and three screws internal fixation can obtain good anatomical reduction rate and therapeutic effect in the treatment of abduction and insertion femoral neck fracture.
