A study was undertaken to evaluate the use of ORTHOSORB absorbable pin fixation for distal first ray osteotomies, in the management of hallux valgus. Data presented include 20 osteotomies fixated with ORTHOSORB absorbable pins in a crossing fashion, performed in 14 patients with an average follow-up period of 11 months. The patient population presented with an average age of 30, all were female. The patient pool was evaluated for hallux abductus, metatarsus primus varus, tibial sesamoid position, quality and quantity of range of motion at the first metatarsophalangeal joint, metatarsalgia, and osteolysis, both before and after surgery. No osteotomy displacement, delayed healing, or osteonecrosis was noted in this study. No adverse clinical reactions were observed in response to the ORTHOSORB pins.

Objective: By comparing the hip arthroplasty parameters planned with the AIHIP three-dimensional simulation surgery system, this study analyzes the accuracy of the new femoral-side "shoulder-to-shoulder" artificial anatomical marker positioning method in femoral-side prosthesis implantation and the prevention of leg length discrepancy in hip arthroplasty.
Methods: A retrospective collection of 47 patients who underwent initial total hip arthroplasty at our hospital from August 2020 to December 2022 and met the inclusion and exclusion criteria was used as the study subjects. The average age was 67.

Background: It is known that open wedge high tibial osteotomy (OWHTO) may lead to progression of patellofemoral degeneration due to descent of the patellar height. However, the difference in patellofemoral joint (PFJ) loads with normal daily activity between uniplane and biplane osteotomies is unclear. The purpose of this study was to reveal the differences in PFJ biomechanics between uniplane and biplane OWHTO using finite element analysis (FEA).

Hallux valgus (HV) presents as a common forefoot deformity that causes problems with pain, mobility, footwear, and quality of life. The most common open correction used in the UK is the Scarf and Akin osteotomy, which has good clinical and radiological outcomes and high levels of patient satisfaction when used to treat a varying degrees of deformity. However, there are concerns regarding recurrence rates and long-term outcomes.

Objective: To explore weight-bearing stability of Pilon fracture fixed by external fixator.
Methods: Six ankle bone models (right side) and 4 pairs (8 ankle cadaver specimens) were selected. Pilon fracture model was prepared by using the preset osteotomy line based on Ruedi Allgower Pilon fracture type.
