Background: This study describes the anatomy and incidence of the metatarsophalangeal (MTP) joint meniscus, a structure not mentioned before in literature.
Methods: An anatomical cadaver study on 102 feet was performed with special attention to the first MTP joint anatomy. These results were compared with the per-operative findings in a clinical prospective study on 100 consecutive hallux valgus surgeries.
Results: On cadavers this meniscus is more common in patients with hallux valgus. Clinically, in patients with a mild hallux valgus the meniscus is found in more than half of cases during surgery, while it is seldom found in patients with moderate or severe deformities.
Conclusions: The presence of this structure seems to stabilize the MTP joint preventing progression of the hallux valgus deformity and may explain the pain, which is often seen in mild bunions in younger, patients. Once the rotational deformity increases the meniscus tears and slips into the joint. In the more advanced hallux valgus deformity this meniscus plays little function and seems to disappear, leading to arthrosis.

This study aimed to determine whether hallux pronation influences the proximal to distal phalangeal articular angle (PDPAA) and evaluate its relationship with postoperative recurrence. We included 94 hallux valgus (HV) patients who underwent distal chevron metatarsal osteotomy (DCMO) alone (DCMO-only group, n = 15) and DCMO with Akin osteotomy (DCMO + Akin group, n = 79). Preoperative additional toe radiographs were taken under supination stress to position the pronated toe as a true anteroposterior orientation.

Opioids are often part of the post-operative pain regimen after orthopaedic surgery. Novel multimodal post-operative pain control regimens have been developed to decrease the amount of opioid usage due to their negative side effects including nausea, constipation, and addiction. The purpose of this study was to compare the cost of postoperative pain management treatment methods after orthopaedic surgery between opioid/acetaminophen therapy and an opioid-free, multidrug, multimodal pathway.

Background/aim: Hallux valgus (HV) is the most common deformity of the forefoot. Although HV has been strongly associated with a family history, its genetic underpinnings remain unclear. Few studies have examined the relationship between folic acid metabolism, which is critical in normal bone development, and HV.

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.

Background: This study aimed to compare the prevalence of hallux valgus interphalangeus (HVI) in juvenile-onset hallux valgus and adult-onset hallux valgus and to analyze the correlation between the hallux interphalangeal angle (HIA) and other radiographic parameters in juvenile-onset hallux valgus.
Methods: This retrospective study included 640 feet and 320 patients with hallux valgus (160 juvenile-onset and 160 adult-onset cases). Eight radiographic parameters were measured: HIA, hallux valgus angle, intermetatarsal angle, talonavicular coverage angle, anteroposterior talocalcaneal angle, lateral talocalcaneal angle, lateral talo-first metatarsal angle, and calcaneal pitch.
