Purpose: To evaluate the clinical results of modified peroneal sulcus deepening combined with superior peroneal retinaculum repair in peroneal tendon subluxation treatment.

Methods: From 2016 to 2020, 18 patients with peroneal tendon subluxation were diagnosed and treated; all patients underwent modified peroneal sulcus deepening combined with superior peroneal retinaculum repair. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society ankle-hindfoot (AOFAS-AH) score, and subjective patient satisfaction were evaluated before surgery and during follow-up.

Transcription Factor SP2 Regulates Ski-mediated Astrocyte Proliferation In Vitro.

Transcription factors bind specific sequences upstream of the 5' end of their target genes to ensure proper spatiotemporal expression of the target gene. This study aims to demonstrate that the transcription factor SP2 regulates expression of the Ski gene, which has specific binding sites for SP2, and thus enables Ski to regulate astrocyte proliferation. The upstream regulation mechanism of astrocyte proliferation was explored to further regulate the formation of glial scar in specific time and space after spinal cord injury.

High-Energy Transsyndesmotic Ankle Fracture Dislocation: A Case Report and Systematic Literature Review.

High-energy trauma can cause transsyndesmotic ankle fracture dislocation. These fractures are quite rare. Here we present a clinical case of a male patient with this type of injury.

[One-stage bone grafting combined with non-contact plate technique for treatment of post-traumatic femoral osteomyelitis and bone defects].

Eight patients with femoral osteomyelitis were admitted in Lanzhou General Hospital of PLA between July 2012 and July 2015. During the operation the femur was fixed with non-contact locking plate after thorough debridement. Iliac morselized cancellous bones without cortical bone were filled in the bone defect after debridement.

[Surgical treatment strategy for flatfoot related with accessory navicular].

Accessory navicular source flatfoot is one of the foot deformity of clinical common disease,its treatment method is more controversial, differences in clinical efficacy of different surgical methods, according to accessory navicular source flatfoot symptoms of surgical treatment,there is no uniform standard, around a pair of accessory navicular excision how to reconstruct the arch produced a series of operation methods, the clinical curative effect of different operative methods produce also different, how to develop the operation strategy, choose operation method, and after acessory navicular excision whether to rebuild posterior tibial tendon, how to rebuild, the problems such as how to rebuild is the research hotspot and difficulty, looking forward to further research.

Uniaxial repetitive mechanical overloading induces influx of extracellular calcium and cytoskeleton disruption in human tenocytes.

Tendon calcification is common in the Achilles tendon, and injuries affect not only athletes, but also the general population. However, the underlying cellular mechanisms are not yet fully understood. In this study, we isolated healthy human tenocytes and subjected them to uniaxial mechanical stretching (at 1.

[Short-term effectiveness of suture anchor after debridement of extensor tendon insertion for recalcitrant lateral epicondylitis].

Objective: To analyze the short-term effectiveness of repairing musculus extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC) tendon using suture anchor after debridement of extensor tendon insertion for recalcitrant lateral epicondylitis.

Methods: Between March 2009 and May 2011, 10 patients (10 elbows) with recalcitrant lateral epicondylitis received repair of the ECRB and EDC tendon to the lateral epicondyle using a single suture anchor after debridement of extensor tendon insertion. There were 6 males and 4 females with an average age of 45.

[Coracoplasty with mini-incision for treatment of subcoracoid impingement syndrome].

Objective: To investigate the method and effectiveness of coracoplasty with mini-incision for subcoracoid impingement syndrome.

Methods: Between May 2006 and September 2011, 4 patients with subcoracoid impingement syndrome were treated, including 3 cases of congenital dysplasia of the coracoid process and 1 case of anterior glenohumeral instability. There were 3 males and 1 female with an average age of 36 years (range, 20-56 years).

[Percutaneous achilles tendon lengthening through double hemisection in the treatment of achilles contracture syndrome].

Objective: To explore the surgical approach of percutaneous double hemisection and evaluate its clinical efficacies.

Methods: From May 2006 to November 2011, a total of 59 patients were recruited. There were 36 males and 21 females with a mean age of 38.

[Excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular for treatment of flatfoot related with accessory navicular].

Objective: To analyze the excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular for the treatment of flatfoot related with accessory navicular and to evaluate its effectiveness.

Methods: Between May 2006 and June 2011, 33 patients (40 feet) with flatfoot related with accessory navicular were treated. There were 14 males (17 feet) and 19 females (23 feet) with an average age of 30.
