Methods: The clinical data of 30 patients (48 feet) who were diagnosised hallux valgus associated with mild to moderate metatarsus adductus and treated by Scarf osteotomy and Akin osteotomy combined with soft tissue procedures between February 2013 and May 2015 were analyzed retrospectively. There were 2 males (2 feet) and 28 females (46 feet) with an average age of 29.

[Effectiveness comparison between Scarf osteotomy combined with Akin osteotomy fixed by absorbable screws and fixed by metal screws for the treatment of moderate to severe hallux valgus].

Objective: To evaluate the effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus with absorbable screws or metal screws fixation by clinical and radiological data.

Methods: Between March 2014 and May 2016, the Scarf osteotomy combined with Akin osteotomy was used to treat 62 patients (83 feet) with moderate to severe hallux valgus. Twenty-five patients (35 feet) were fixed by absorbable screws (group A) and 37 patients (48 feet) were fixed by metal screws (group B).

[Comparison of accuracy between robot-assisted and fluoroscopy-guided percutaneous pedicle screw placement for treatment of lumbar spondylolisthesis].

Objective: To explore the clinical application value of the spinal robot-assisted surgical system in mild to moderate lumbar spondylolisthesis and evaluate the accuracy of its implantation.

Methods: The clinical data of 56 patients with Meyerding grade Ⅰ or Ⅱ lumbar spondylolisthesis who underwent minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) between January 2017 and December 2017 were retrospectively analysed. Among them, 28 cases were preoperatively planned with robotic arm and percutaneous pedicle screw placement according to preoperative planning (group A); the other 28 cases underwent fluoroscopy-guided percutaneous pedicle screw placement (group B).
