Deltoid ligament injury is common in the daily activities, unlike some other diseases, mechanism of deltoid ligament injury is relatively clear with less controversies, but the consistent standard for its diagnosis and treatment has not yet formed. Whether the stress X-ray as the main basis for diagnosis, MRI check for early application, and the indications of surgical exploration and so on, these are not unified. In the international, especially the conservative treatment and surgical treatment has been existing two major differences. In the choice of surgical treatment, domestic and foreign experts have respective preference. In recent years, domestic researchers emphasis to repair with suture anchors, while abroad it has been mainly to reconstruct the deltoid ligament.

At present, treatment for chronic radial head dislocation mainly focus on open reduction, and conservative treatment is invalid. While the surgical procedure generally applies to extend ulnar, short radial, reset radial head. Repair or reconstruction of annular ligament is the focus of study. For the dysfunction, radial head resection served as the final choice. Early diagnosis is the key to the treatment of chronic radial head dislocation. While ulnar or radial osteotomy and non-reconstruction of annular ligament is still the main trend of today.

Ligamentous injuries of the lower limb are a common entity sustained during sports activities and military training. Magnetic resonance (MR) imaging of the knee and ankle is playing an increasingly important role in the detection, diagnosis and prognosis of these injuries and their associated complications. MR imaging with its exquisite soft tissue contrast resolution and multiplanar capability is increasingly seen as the modality of choice for evaluating ligamentous injuries of the knee and ankle. Representative knee and ankle MR studies from a tertiary referral hospital are used to illustrate both the normal appearance and typical radiological features of common ligamentous injuries of the knee and ankle. A thorough understanding of the MR appearances of these injuries is crucial to the radiologist and clinicians involved in the management of these patients.

OBJECTIVE: To conduct a preliminary study on joint injuries of anterior and calcaneal fibular ligaments of the lateral ankle joint, and to analyze mechanism of action of shaking and poking in treating ankle joint and biomechanical properties of ankle during the recovery of joint injuries. METHODS: CT scan was performed on a male volunteer with right ankle sprain. Mimics 10.0, Solidworks 2016, Hypermesh 12.0 and Abaqus 6.13 software were used to establish 3D nonlinear finite element analysis model of foot and ankle, and the validity of model was verified. Combined with clinical study, the finite element simulation analysis was carried out on the toe flexion, dorsiflexion, varus and valgus of ankle joint under different treatment periods by adjusting elastic modulus of ligament to simulate ligament injury. RESULTS: With the treatment of shake and prick and recovery of ligament injury, the maximum stress and area with large stress on tibial pitch and fibular joint surface gradually increased under the four working conditions, and the stress value of the maximum stress ligament gradually increased, and the stress of the anterior and calcaneal fibular ligament dispersed and transferred, and the axial force gradually decreased. CONCLUSION The finite element method was used to simulate the mechanical condition of the shaking and stamping technique, and the changes of the forces of the ligament and articular surface before and after treatment of anterior and calcaneal ligament combined injury of ankle talus were intuitively observed. The treatment effect was quantified, and could provid objective and scientific basis for clinical promotion and application of this technique.

OBJECTIVETo analyze the reliability of magnetic resonance imaging (MRI) in detecting posterior ligament complex injury in thoracolumbar fractures.

METHODSNinety-five patients with thoracolumbar fracture were evaluated by palpation of the inter-spinal gap, plain radiography, and MRI before operation. In addition to conventional MRI sequences, a fat-suppressed T2-weighted sagittal sequence was performed. Surgery was performed by a posterior approach. During the operation, posterior ligament complex was examined.

RESULTSA wide inter-spinal gap was palpated in 41 patients and was found in 55 patients on plain radiography. According to MRI, injury to the supraspinal ligament was suspected in 85 patients, the inter-spinal ligament in 83 patients, and the ligamentum flavum in 26 patients. There were 82 supraspinal ligament injuries, 80 inter-spinal ligament injuries, and 20 ligamentum flavum injuries in operative findings. The relations between plain radiography and operative findings, between MRI interpretation and operative findings were statistically significant.

CONCLUSIONA fat-suppressed T2-weighted sagittal sequence of MRI is a highly sensitive, specific, and accurate method to detect posterior ligament complex injury and which is recommended for the accurate evaluation of posterior ligament complex injury in thoracolumbar fractures.

Ligament injury always has an unsatisfied outcome because of the poor blood supply and scar tissue formation. This may result in severe joint dysfunction. Tissue engineering, as a most prospective field, may provide an effective approach for the treatment of ligament injury. This paper has reviewed some recently published articles focusing on the sources of seed cells in ligament tissue engineering, application of growth factors, screening of scaffold materials with specific mechanical and biodegradable properties, and interaction between cells and scaffold materials. At present, what should be extensively studied are scaffolds with specific mechanical and biodegradable properties, and bioreactors providing three-dimensional culture microenvironment mimic in vivo.

Fractures of the tibial condyles, involving as they do weight-bearing articular surfaces and frequently accompanied by soft tissue injuries such as collateral ligaments, cruciate ligaments, and menisci present a variety of problems in treatment and prognosis. Slee, Apley, and others maintained the opinion that most fractures of the tibial condyles could be managed conservatively. On the other hand, Rombold, Schatzker, and others seemed to consider closed treatment to be virtually s form of therapeutic nihilism and adviced open reduction. But recently most authors agree that the method of treatment has to be selected in each individual case, and recommand anatomical reduction of the fracture as possible and early knee motion. The authors have treated 17 cases of tibial condylar fractures with arthroscopic management and extraarticular distal approach in the Department of Orthopedic surpery, Kang Dong Sacred Heart Hospital from Oct. 1986 to Jul. 1989. Of the above cases, 11 cases could be followed for a period of anywhere from 1 year to 31/2 years and analysed according to the cause, classification, treatment, and result. The following results were obtained from the analysis of 11 tibial condylar fractures. l. Of the 11 cases, 7 (63.6%) were male and 4 (36.4%) were female. 2. Of the 11 cases, 7 (63.6%) were due to traffic accident (5 pedestrians, 2 occupants) and 3 (27.3%) were due to fall from height. 3. Among 11 cases, 7 (63.6%) were associated with other injuries. 4. Bone graft was needed in 5 cases. 5. All were treated by arthroscopic management with anatomically and functionally good results. 6. By arthroscopic mangement, it was easy to find and treat the accompanying intraarticular lesion. 7. With early active and C.P.M. exercise, almost full range of motion was obtained in all cases.
