Percutaneous Repair Technique for Acute Achilles Tendon Rupture with Assistance of Kirschner Wire.

The aim of this study is to introduce a self-designed, minimally invasive technique for repairing an acute Achilles tendon rupture percutaneously. Comparing with the traditional open repair, the new technique provides obvious advantages of minimized operation-related lesions, fewer wound complications as well as a higher healing rate. However, a percutaneous technique without direct vision may be criticized by its insufficient anastomosis of Achilles tendon and may also lead to the lengthening of the Achilles tendon and a reduction in the strength of the gastrocnemius.

Femoral Condyles Tangential Views: An Effective Method to Detect the Screw Penetration of Femoral Condyles After Retrograde Nailing.

Background: Postoperative knee soft tissue irritation is a common complication after retrograde nail fixation of femoral fractures. Distal locking screw prominence is one of the causes for soft tissue irritation. This study aimed to determine whether the use of the femoral condyles tangential views improve the diagnostic accuracy compared with anteroposterior (A-P) view in detecting distal locking screw penetrations during retrograde femoral nailing.

Relationship between developmental canal stenosis and surgical results of anterior decompression and fusion in patients with cervical spondylotic myelopathy.

Background: Anterior cervical decompression and fusion (ACDF) has long been the preferred treatment for cervical spondylotic myelopathy (CSM). However, few studies have focused on surgical results of CSM in patients with developmental canal stenosis (DCS). The purpose of this study was to investigate DCS as a comorbidity in patients with CSM and the correlation between surgical results and DCS.

Femoral stress and strain changes post-hip, -knee and -ipsilateral hip/knee arthroplasties: a finite element analysis.

Objective: To identify the optimal ratio of free femur for minimizing the risks of periprosthetic fracture.

Methods: Three dimensional models of the femur with hip and knee stem elongation were constructed. With the distal femoral condylar surface fixed in a three dimensional model, the femoral head loading was performed according to the methods described by Huiskes and van Rietbergen in the models of hip replacement, knee replacement with or without hip stem or knee stem elongation.

Closed patella fracture combined with cruciate ligament injury: a case control study.

Background: Patellar fracture and cruciate ligament injury are a common consequence of traumatic knee injury. Patellar fracture combined with cruciate ligament injury is rarely reported, although the mechanisms of two things are similar. This study aimed to evaluate the incidence of closed patella fracture combined with cruciate ligament injury.

Biomechanical comparison of gourd-shaped LCP versus LCP for fixation of comminuted tibial shaft fracture.

The purpose of this study was to compare monotonic biomechanical properties of gourd-shaped LCP fixation with LCP fixation of human tibial shaft in gap fracture mode. Twenty paired fresh cadaveric human tibias were randomly divided into 4 groups (5 pairs each): (1) axial loading single cycle to failure testing, (2) torsion single cycle to failure testing, (3) 4-point bending single cycle to failure testing, and (4) dynamic 4-point bending testing. A 7-hole 4.

Quantitative score system for the surgical decision on adult femoral neck fractures.

Surgical decision making for femoral neck fractures is currently based on factors such as patient age, fracture type, and medical condition, lacking a quantitative standard. The treatment protocol based on such qualitative assessment has poor operability, greatly affected by the surgeon's subjective factors. As a result, a quantitative score system (QSS) focusing on 5 factors--age, fracture type, bone mineral density, activities of daily living, and medical comorbidities--with a total score of 25 is designed to deal with adult femoral neck fractures.
