The loss of a limb results in major disability and psychological trauma to the affected individual. Amputees of dysvascular origin usually have multiple co-morbidities and their complicated post-operative course frequently leads to a prolonged hospitalisation or a subsequent amputation in a higher level of the limb. The integrated comprehensive approach by a interdisciplinary team in post-operative management starts immediately after a limb amputation to assure successful surgical and functional outcomes. The programme comprises a variety of medical and rehabilitation aspects: to control acute medical co-morbidities, evaluate and alleviate different types of pain, optimal wound care, condition the residual limb to be well-fitted with a prosthesis, address patient’s functional goals and achieve maximal independence in mobility and self care, coach ideal coping skills and provide psychosocial support, and educate patient and family about risk factor modulation and residual limb care. Aggressive oedema control and early mobilisation became standardised practice in post-amputation care in view of a number of advantages.

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

Despite the overall satisfactory results of total hip arthroplasty, post-operative complications continue to occur. To minimize these problems, computer-assisted total hip arthroplasty using navigation or robot-assisted systems is being developed. A navigation system is defined as a system that locates a position in three-dimensional space and traces the target spot, and a robot-assisted system is defined as a system that performs operations automatically with mechanical robot arms based on prior preoperative planning. Computer-assisted surgeries have shown superior results to conventional methods in implant positioning, fixation, and accurate lower extremity alignment in the limited reports available. However, computer-assisted surgeries take longer compared to conventional methods. Due to the extra time needed, the risk of postoperative infection and blood loss is considered to be higher. Nevertheless, robot-assisted system is being developed for the field of hip arthroplasty, and thus its efficacy and accuracy needs to be further investigated. Since these methods have other advantages compared to conventional methods, they are the focus of much interest.

Posterior tibial slope angle (PTSA) is a risk factor for anterior cruciate ligament (ACL) injury and has attracted a lot of attention, but its mechanism of action and diagnosis are still not systematically studied in the field of sports medicine. In this paper, we believe that PTSA should be measured by full-length lower extremity films and combined with multiple imaging data for comprehensive assessment to reduce errors. A large PTSA may increases risk of anterior cruciate ligament injury, so patients with more than 12 degrees of PTSA should be treated by preserving meniscus as much as possible during ACL reconstruction and combining with tibial osteotomy if necessary, which could effectively prevent risk of ligament re-injury. At the same time, gait analysis has an important reference value for preoperative pathogenic pattern and postoperative rehabilitation function, so the author believes that it will have a guiding significance for the development of individualized rehabilitation strategy based on PTSA, in order to achieve the best treatment effect.

OBJECTIVE: To summarize the progress of research related to the surgical treatment of recurrent patellar dislocation by peripatellar osteotomy in clinical practice, in order to provide reference for clinical treatment. METHODS: The recent literature on peripatellar osteotomy for recurrent patellar dislocation at home and abroad was reviewed, and the bony structural abnormalities, imaging diagnosis, and treatment status were summarized. RESULTS: Abnormalities in the bony anatomy of the lower limb and poor alignment lead to patellofemoral joint instability through the quadriceps pulling force line and play an important role in the pathogenesis of recurrent patellar dislocation. Identifying the source of the deformity and intervening with peripatellar osteotomy to restore the biomechanical structure of the patellofemoral joint can reduce the risk of soft tissue surgical failure, delay joint degeneration, and achieve the target of treatment. CONCLUSION In the clinical diagnosis and treatment of recurrent patellar dislocation, the factors causing patellofemoral joint instability should be comprehensively evaluated to guide the selection of surgery and personalized treatment.

Surgical management of femoral shaft fractures with intramedullary nails has become the standard of care, with multiple options for entry point described, including piriformis entry, trochanter entry and retrograde femoral nails. Our present review describes the surgical anatomy of the proximal and distal femur and its relation to different entry points for intramedullary femoral nails. In addition, we reviewed relative indications for each technique, difficulties associated and possible complications.

OBJECTIVE: Using the mono-energy reconstruction images and X-ray films to investigate whether the ABG Ⅱ short-stem could improve the filling ratio, stability, and alignment in the Dorr type C femur, compared with the Corail long-stem. METHODS: Among patients who were with Dorr type C femurs and treated with total hip arthroplasty between January 2006 and March 2012, 20 patients with a Corail long-stem (Corail group) and 20 patients with an ABG Ⅱ short-stem (ABG Ⅱ group) were randomly selected. The differences in gender, age, body mass index, and preoperative diagnoses between the two groups were not significant ( P>0.05). The ABG Ⅱ group was with a mean follow-up of 142 months (range, 102-156 months), and the Corail group was with a mean follow-up of 107 months (range, 91-127 months). There was no significant difference in the Harris score and subjective satisfaction score between the two groups at last follow-up ( P>0.05). At last follow-up, dual-energy CT scans with mono-energy image reconstruction were used to calculate the prosthetic filling ratio and to measure the alignment of the prosthesis in the coronal and sagittal positions. Stability assessment was performed based on X-ray films, and the subsidence distance was measured using EBRA-FCA software. RESULTS: X-ray film observation showed that the prostheses in the two groups were stable and no signs of loosening was found. The incidence of pedestal sign was significantly lower in the ABGⅡ group than in the Corail group ( P<0.05), and the incidence of heterotopic ossification was significantly higher in the ABGⅡ group than in the Corail group ( P<0.05). The subsidence distance of femoral stem in ABG Ⅱ group was significantly greater than that in Corail group ( P<0.05), and the subsidence speed of femoral stem in ABG Ⅱ group was also greater than that in Corail group, but the difference was not significant ( P>0.05). The overall prosthesis filling ratio was significantly higher in the ABG Ⅱ group than in the Corail group ( P<0.05), while the coronal filling ratio at the lesser trochanter, 2 cm below the lesser trochanter, and 7 cm below the lesser trochanter were not significant ( P>0.05). The results of prosthesis alignment showed that there was no significant difference in the sagittal alignment error value and the incidence of coronal and sagittal alignment error >3° between the two groups ( P>0.05), while the coronal alignment error value in the ABG Ⅱ group was significantly greater than that in the Corail group ( P<0.05). CONCLUSION Although the ABG Ⅱ short-stem avoids the distal-proximal mismatch of the Corail long-stem in the Dorr type C femur and thus achieves a higher filling ratio, it does not appear to achieve better alignment or stability.
