An interpretable deep learning model for hallux valgus prediction.

Background: This work developed an interpretable deep learning model to automatically annotate landmarks and calculate the hallux valgus angle (HVA) and the intermetatarsal angle (IMA), reducing the time and error of manual calculations by medical experts and improving the efficiency and accuracy of hallux valgus (HV) diagnosis.

Methods: A total of 2,000 foot X-ray images were manually labeled with 12 landmarks by two surgical specialists as training data for the deep learning model. The important parts of the foot X-ray images centered on the proximal phalanx of the bunion (PH1), the first metatarsal (MT1), and the second metatarsal (MT2) were segmented using the proposed AG-UNet in the study.

Modified extensile calcaneal exposure is safe.

Objective: The objective of this study was to evaluate the effect of open reduction and internal fixation for displaced intra-articular calcaneal fractures through a modified tarsal sinus incision.

Methods: A retrospective review over 3 years of the clinical data of patients with intra-articular calcaneal fractures treated with open reduction and internal fixation through lateral hook curvy incisions. The efficacy of the 25 lateral hook curvy incisions was analyzed.

Anatomy of the Plantar Intermetatarsal Tunnel: A Cadaveric Study.

The contents of the plantar intermetatarsal tunnel (PIMT) and the relationship between the common plantar interdigital nerve (CPIN) and the PIMT were recorded. The width of the PIMT was measured at the metatarsal neck (MTN), metatarsophalangeal (MTP) joint and the base of the proximal phalanx (BPP). The length of the deep transverse metatarsal ligament (DTML), the PIMT and the intracapsular ligament (ICL) were also measured.

Surgical Anatomy of the Medial Cuneiform (Cotton) Osteotomy.

Background: The Cotton osteotomy, or dorsal-opening wedge osteotomy of the medial cuneiform (MC), is used to address medial column alignment to restore the static-triangle of support. There are many described techniques regarding the incision and osteotomy. Successful completion of the osteotomy requires knowledge of the anatomy, particularly the location of the medial dorsal cutaneous nerve (MDCN).

Anatomy of the Distal End of Flexor Digitorum Longus Tendon and Percutaneous Release Technique: A Cadaveric Study.

Background: The transfer of flexor-to-extensor is widely used to correct lesser toe deformity and joint instability. The flexor digitorum longus tendon (FDLT) is percutaneously transected at the distal end and then routed dorsally to the proximal phalanx. The transected tendon must have enough mobility and length for the transfer.

Arthroscopic treatment combined with the ankle stabilization procedure is effective for sinus tarsi syndrome in patients with chronic ankle instability.

Purpose: This study aimed to investigate the results of arthroscopic treatment combined with ankle stabilization procedure for sinus tarsi syndrome (STS) in patients with chronic ankle instability (CAI).

Methods: A total of 57 patients (31 males and 26 females, average age 29.9 ± 8.

A Long-Term Study of the Effect of Subtalar Arthrodesis on the Ankle and Hindfoot Joints.

Background: Subtalar arthrodesis is a common therapy for subtalar joint disorders. In this article, we evaluate the effect of subtalar arthrodesis on the ankle and hindfoot joints.

Methods: Fifty patients (33 men and 17 women) underwent subtalar arthrodesis between January 1, 1996, and August 31, 2011.

A retrospective clinical study on 37 subtalar arthrodesis patients of nine years follow-up.

Background: Subtalar arthrodesis is a common therapy for subtalar joint disorders. In this article, we evaluate the effect of subtalar arthrodesis on the ankle and hindfoot joints.

Methods: Fifty patients (33 men and 17 women) underwent subtalar arthrodesis between January 1, 1996, and August 31, 2011.

Cluster of differentiation 44- and octamer-binding transcription factor-4-positive stem-like osteosarcoma cells involved in tumor development.

Osteosarcoma (OS) is an aggressive primary bone cancer that usually affects children and young adolescents. Previous studies have demonstrated the implications of a small sub-population of cancer stem cells on treatment failure and tumor recurrence. The present study analyzed the characteristic features of the stem-like cells within the human OS-55 cell line.

Serum levels of 25-hydroxyvitamin D and functional outcome among postmenopausal women with hip fracture.

Objective: The main objective of the current study was to assess the distribution and its prognostic value of serum 25-hydroxyvitamin D (25[OH] D) levels assessed at admission in Chinese postmenopausal women with hip fracture.

Methods: From January 1, 2012 to December 31, 2013, all postmenopausal women with first-ever hip fracture were recruited to participate in the study. Serum 25[OH] D levels were measured at admission.
