Aims:
The aim of this study was to evaluate outcomes and fusion rates of 4 different methods of first metatarsophalangeal joint (MTPJ) arthrodesis.
Methods:
We performed a retrospective analysis of first MTPJ fusion using Bold® and Acutrak® compression screws, universal 1/3 tubular plate and Hallu®-S non-locking plate in 6 hospitals in Dublin over 4 years. A cohort of 300 patients (351 feet) was operated on by 3 feet and ankle fellowship trained orthopaedic surgeons (PK, MMS, JVMcK) over 4 years. Mean age was 62.4 years. There were 261 females and 39 males. One hundred three patients had a fusion of first MTPJ using two Acutrak® screws and 90 with two Bold® screws. Sixty-five were fused with the Hallu-S® plate and 42 with the universal 1/3 tubular plate. Patients were evaluated clinically and radiographically at 6 weeks, 3 months and 12 months.
Results:
Functional outcome scores performed using Manchester-Oxford Foot Questionnaire (MOXFQ). Failure rate in those fused with the Hallu®-S plate was 0%, Acutrak® screws 2.4%, Bold® screws 9.5% and universal 1/3 tubular plate 12.5% (p > 0.12). All treatment groups demonstrated significantly reduced MOXFQ scores (p value < 0.05).
Conclusion:
In this retrospective study for first MTPJ fusion, a low profile, pre-contoured plate in combination with a screw mode had the best results with no failure rates and improved MOXFQ scores.
Level Of Clinical Evidence:
IV, retrospective study.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

Method of Joints
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...
