Bilateral Tibial Tuberosity Periosteal Sleeve Fracture in an Adolescent: A Case Report

@#Tibial tuberosity avulsion fracture is a rare injury, and bilateral occurrence is more uncommon. Periosteal sleeve fracture is a unique fracture pattern which was first described in the lower pole of patella in children. We are reporting a rare case of bilateral tibial tuberosity sleeve fracture in a teenage boy which occurred while sprinting. The patient underwent open reduction, pull through suture fixation of the bilateral tibial tuberosity and screw fixation of left tibial tuberosity. Post-operative rehabilitation included gradual increment of range of motion with hinged brace and quadriceps muscle strengthening. Close follow-up was done to monitor the progression of his recovery. At six months follow-up, the patient recovered well. Both knees had full range of motion with an intact extensor mechanism.

Short-term effectiveness of ultrasound-guided Kirschner wire provocation technique in treatment of Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents / 中国修复重建外科杂志

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.

Periosteum: Functional Anatomy and Clinical Application

@#Periosteum is a connective tissue that envelopes the outer surface of bones and is tightly bound to the underlying bone by Sharpey’s fibers. It is composed of two layers, the outer fibrous layer and the inner cambium layer. The periosteum is densely vascularised and contains an osteoprogenitor niche that serves as a repository for bone-forming cells, which makes it an essential bone-regenerating tissue and has immensely contributed to fracture healing. Due to the high vascularity of inner cambium layer of the periosteum, periosteal transplantation has been widely used in the management of bone defects and fracture by orthopedic surgeons. Nevertheless, the use of periosteal graft in the management of bone defect is limited due to its contracted nature after being harvested. This review summarizes the current state of knowledge about the structure of periosteum, and how periosteal transplantation have been used in clinical practices, with special reference on its expansion.

Anterior staphyloma repair following trauma and surgery – A retrospective review of techniques and outcomes over 25 years

Purpose: To review surgical options, techniques, and outcomes of anterior staphyloma repair done following trauma and surgery. Methods: This was a retrospective case study of patients who underwent staphyloma repair with scleral or tibial periosteal patch grafts following trauma and surgery with a minimum follow-up of 3 months postoperatively. Preoperative risk factors, choice of graft materials, surgical details, and outcomes in terms of graft uptake and tectonic integrity were analyzed. Results: Seventeen eyes of 17 patients underwent successful staphyloma repair (scleral 15, tibial periosteal two). Mean follow-up was 47.1 months (3–159 months). Postoperative intraocular pressure rise noted in four eyes was controlled medically or surgically. Three patients underwent successful repeat patch grafting (graft melt one and recurrent ectasia two). Tectonic integrity of the eyeball was restored and maintained in all patients at the final follow-up. Conclusion: Comprehensive evaluation of the risk factors, control of ocular comorbid conditions, and early and meticulous surgery can optimize results.

Saphenous vascular periosteal flap in prevention of bone bridge formation after epiphyseal plate injury: An experimental study / 中华显微外科杂志

Objective:To establish a model of epiphyseal plate injury in juvenile rabbits and explore the effect of periosteum flap with saphenous artery on preventing the formation of bone bridge after epiphyseal plate injury.Methods:From July 2017 to January 2018, 30 young New Zealand immature rabbit were randomly grouped into 3 groups (group A, B and C, with 10 rabbits per group). The blood vessels of knee joint were dissected and a periosteum flap with saphenous artery were designed. A model of distal femoral epiphyseal plate injury was established in immature rabbits with a 3.0 mm Kirschner wire on one side of the distal femoral epiphyseal plate as experimental side, and the other side of the distal femoral epiphyseal plate was assigned as control side. The injured epiphysis were prepared and described as follow: in experimental side of group A, a piece of periosteum with the same size as that in group C was resected and discarded. In experimental side of group B, a periosteal flap without vascular pedicle was filled in the injured area. And in experimental side of group C, a periosteum flap with saphenous artery was filled in the injured area. The length and varus angle of femur specimens of length and varus angle of femur specimens wihthin groups were measured at 24 weeks after surgery to evaluate the effect on bone growth in epiphyseal plate injury. The effect of the periosteum flap with saphenous artery on preventing a formation of bone bridge was assessed by section view of decalcified specimens, HE staining and toluidine blue staining. The measured data were expressed as Mean and standard deviation (Mean±SD), and data were compared within and between the groups using one-way analysis of variance (ANOVA). P<0.05 was considered as statistically significant. Results:The femur of experimental side of group A and B showed obvious short with valgus deformity compared with that of control side, and the difference of length and varus angle of femur specimens wihthin groups was statistically significant ( P<0.05). There were no significant differences in the length and valgus angle of the femur between experimental side and its control side in group C ( P>0.05). In experimental side of group A, there were bone bridges in the epiphyseal lesion area, with a clear boundary to the surrounding epiphyseal plate. In experimental side of group B, the periosteum flap in the injured area was absorbed, accompanied by the formation of a few pale white bone tissue, and with a clear boundary to the surrounding epiphyseal plate. In experimental side of group C, the lesion area was filled with milky white cartilage tissue with the same colour as the epiphyseal plate, and with an unclear boundary with the epiphyseal plate. HE stain and toluidine blue staining showed that the injured area of group A was filled with a large number of bone tissue, but no obvious cartilage tissue was observed. In group B, the area of lesion was filled mainly with fibrous tissue, with a small amount of bone tissue. In group C, a large number of hyaline cartilage tissues were formed along the tunnel of the injury area, and closely connected with the normal epiphyseal plate. Conclusion:Filling a periosteum flap with saphenous artery after epiphyseal plate injury can prevent the formation of bone bridge and prevent the affected limb form shortening and angulation.

Effects of McLaughlin Bennett Treriri straight wire technique on the content of periostin in gingival crevicular fluid of the maxillary first molar / 中国基层医药

Objective:To investigate the effects of McLaughlin Bennett Treriri (MBT) straight wire technique on the content of periostin in gingival crevicular fluid of the maxillary first molar.Methods:Ninety patients with malocclusion who were treated with MBT straight wire technique in Jiaxing Hospital of Traditional Chinese Medicine from February to September 2021 were included in this study. The patients were divided into group A (13-18 years old) and group B (30-35 years old) according to age, with 45 patients in each group. According to the random number table method, patients in group A were divided into 100 g subgroup (group A1, n = 22) and 150 g subgroup (group A2, n = 23), and patients in group B were divided into 100 g subgroup (group B1, n = 22) and 150 g sub group (group B2, n = 23). Effects of age on the content of periostin in gingival crevicular fluid and bite force were observed. The antagonistic effect of periostin in gingival crevicular fluid during the application of different corrective forces was evaluated based on the changes in bite force, bone mineral density and height of the jaw after the application of force. The incidence of complications was calculated. Results:The level of periostin and bite force in group A were (1 249.38 ± 89.29) pmol/L and (1 038.37 ± 79.54) N, respectively, which were significantly higher than (831.54 ± 76.38) pmol /L and (921.45 ± 81.36) N in group B ( t = 23.86, 6.89, both P < 0.05). After 1 and 3 months of treatment, the amplitude of improvement in bite force, jaw bone density, and jaw height in group A2 were greater than those in group A2 ( t = 2.92, 6.39, 0.64, 1.30, 1.07, 2.48, all P < 0.05). After 7 and 14 days of treatment, the level of periostin was increased in both group B1 and B2 and its level in group B2 was significantly higher than that in group B1 ( t = 0.59, 1.89, both P < 0.05). After 1 month of treatment, there were no significant differences in bite force, jaw bone density and jaw height between groups B1 and B2 (all P > 0.05). After 3 months of treatment, the amplitude of improvement in bite force, jaw bone density and jaw height were greater in group B2 than those in group B1 ( t = 0.27, 4.02, 3.07, 1.52, 0.06, 1.57, P < 0.05). There were 3 patients with loose teeth, 2 patients with pulp reaction, 1 patient with mucosal ulcer, and 2 patients with secondary dental caries during treatment. The incidence of complications was 8.89%. Conclusion:MBT straight wire technique is effective and safe in the treatment of patients with dental deformities. The level of periostin in gingival crevicular fluid of the maxillary first molar and bite force decrease with age. The corrective force can increase and activate the expression of periostin, thereby promoting periodontal wound healing and regeneration, and increasing patients' bite force, jaw bone density and height.

Establishing a rat model of atrophic nonunion by using circular external fixator combined with periosteum cauterization / 中国组织工程研究

BACKGROUND: Establishment of a standard experimental animal model of atrophic nonunion is necessary for experimental study and related treatment of atrophic nonunion. However, the common modeling methods cannot accurately simulate atrophic nonunion in the clinical practice. OBJECTIVE: To construct a standard animal model of atrophic nonunion. METHODS: Thirty male Sprague-Dawley rats were randomly divided into experimental and control groups. All animals were subjected to bone cutting at the middle-lower segment of the right tibia and the circular external fixator was applied to keep a 4 mm defect interval. The animals in the experimental group were subjected to an additional cauterization of the periosteum at the fracture end of the tibia with a length of 1 mm. The periosteum was not treated in the control group. The study protocol was approved by the Experimental Animal Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine on January 01, 2018, with approval No. TCMF1-2018002. RESULTS AND CONCLUSION: After modeling, there was one case of loose external fixation in each group, and no infection occurred in both groups. Imaging examination showed no bone connection and no sign of healing between the fractures of the tibia in the two groups at 6 weeks after modeling. Imaging and histological findings showed no healing at the end of fracture but typical atrophic nonunion in the experimental group at 12 weeks after modeling. By contrast, six animals had atrophic nonunion, and eight had hypertrophic nonunion in the control group. Overall, the animal model of atrophic tibial nonunion can be successfully constructed using circular external fixator combined with periosteal cauterization at the fracture end.

Molecular mechanism of icariin in the treatment of bone nonunion / 中国组织工程研究

BACKGROUND: Nonunion is a common clinical complication in orthopedics, which seriously impacts the physical and mental health and quality of life of patients. In recent years, a large number of studies have found that icariin plays a significant role in promoting fracture healing and treating bone defects. Bone nonunion and fracture healing coexist, and the research on the mechanism of fracture healing actually focuses on the treatment of bone nonunion. OBJECTIVE: To review the research progress in the molecular mechanism of icariin in the treatment of bone nonunion. METHODS: The first author used “icariin, bone nonunion, bone marrow mesenchymal stem cells, periosteal cell, osteoblasts, osteoclast” as key words in English and Chinese to search PubMed, CNKI, WanFang and VIP databases. A total of 542 articles were retrieved and screened manually according to the selection criteria and exclusion criteria. Finally, 44 articles were included for result analysis. RESULTS AND CONCLUSION: Icariin can effectively promote fracture healing and treat bone nonunion by promoting the proliferation and differentiation of bone marrow mesenchymal stem cells and periosteal cells, promoting the proliferation and maturation of osteoblasts and inhibiting the osteoclast effect of osteoclasts. However, most of the experiments are still in the basic experimental research, and there is still a need for a large number of clinical studies as well as studies on related proteins and genes, to provide a new idea for the clinical use of Chinese herbs in the treatment of bone nonunion.

Role of periosteum in fracture healing and bone tissue repair / 中国组织工程研究

BACKGROUND: The periosteum is involved in fracture healing and bone tissue repair because it contains cells with osteogenic potential, and its role in repairing bone defects has become a focus of current research. OBJECTIVE: To review the role of periosteum in fracture healing and bone tissue repair. METHODS: A computer-based online search of China National Knowledge Infrastructure database and PubMed was performed for articles regarding the role of periosteum in fracture healing and bone tissue repair published from January 1964 to December 2019. Key words included “periosteum, bone healing, periosteum cells” in English and Chinese. Finally, a total of 48 articles were included to review. RESULTS AND CONCLUSION: (1) The integrity of periosteum plays an important role in fracture healing and bone tissue repair, and has been widely used in bone tissue engineering due to its good osteogenic properties, excellent material properties and barrier effect. (2) The mechanism of periosteum in the process of distraction ostegogenesis is still controversial. It has been confirmed that absence of periosteum does not affect the osteogenic effect of mandibular defects, but the role of periosteum in osteogenic effect of limb defects remains to be further studied.

Síndrome de Goldbloom: síndrome febril prolongado con disproteinemia. Caso clínico / Goldboom's syndrome: prolonged febrile syndrome with dysproteinemia. Case report

El síndrome de Goldbloom es una rara entidad clínica de etiología desconocida que ocurre casi exclusivamente en pediatría. Consiste en un síndrome febril prolongado con hiperostosis perióstica y disproteinemia, que, con frecuencia, simula una patología hematooncológica o linfoproliferativa. El diagnóstico se hace por exclusión de las diferentes causas de dolor de los huesos y se asocia a hipergammaglobulinemia, hipoalbuminemia, eritrosedimentación acelerada e imágenes radiológicas de periostitis. La sintomatología, la radiología y los parámetros de laboratorio remiten en un tiempo variable, que va, habitualmente, de los 3 a los 12 meses. Se presenta a un paciente de 6 años con dolores óseos difusos, hiperostosis perióstica, síndrome febril prolongado de 8 meses de evolución, pérdida de peso y reactantes de fase aguda elevados con disproteinemia (hipergammaglobulinemia e hipoalbuminemia). Debe considerarse el síndrome de Goldbloom en un paciente con las manifestaciones descritas luego de la exclusión de la patología infecciosa, hematooncológica e inflamatoria de otra causa.

Goldbloom syndrome is a rare clinical entity, of unknown etiology that happens almost exclusively in pediatric population. It is a prolonged febrile syndrome with periosteal hyperostosis and dysproteinemia, and often simulates an hematooncology or lymphoproliferative disease. The diagnosis is to rule out the different causes of bone pain associated with hypergammaglobulinemia, hypoalbuminemia, high erythrocyte sedimentation rate and periostitis at the radiographies. Symptomatology, radiology and laboratory parameters refer in a variable time, usually from 3 to 12 months. We report the case of a six-year-old boy with diffuse bone pain, prolonged febrile syndrome (of 8 months of evolution), weight loss and elevated acute phase reactants with dysproteinemia (hypergammaglobulinemia and hypoalbuminemia). Goldbloom syndrome should be considered in patients with prolonged febrile syndrome and cortical hyperostosis after the exclusion of infectious, lymphoproliferative or inflammatory disease.

Periosteal Fixation Applied to Patients with Large-angle Paralytic Strabismus

PURPOSE: To evaluate the effect of periosteal fixation in patients with large-angle paralytic strabismus that was not corrected through conventional strabismus surgery. METHODS: Four eyes of three patients with large-angle paralytic strabismus who underwent periosteal fixation from June 2014 to August 2014 were examined. All patients presented with exotropia > 50 prism diopters (PD). Two of them showed exotropia caused by chronic complete oculomotor nerve palsy; the other two showed exotropia caused by medial rectus muscle injury during endoscopic sinus surgery. RESULTS: The mean preoperative exodeviation using the Krimsky test was 58 ± 29 PD. The postoperative values were 6.5 ± 9.4 PD at 1 week, and 11.25 ± 2.5 PD at 6 months. The mean surgical effect of exodeviation was 43.75 ± 21.36 PD. CONCLUSIONS: Periosteal fixation is an effective surgery for the management of paralytic strabismus that was not corrected through conventional strabismus surgery.
