Hallux valgus, commonly known as a bunion, is a foot condition that affects many people. It is characterized by the misalignment of the first metatarsal bone, leading to a protrusion at the base of the big toe. This can cause discomfort and pain, and in some cases, it may require surgical intervention. One of the key considerations during hallux valgus surgery is the position of the tibial sesamoid, a small bone embedded within the tendons that run to the big toe. The position of this bone relative to the first metatarsal bone is known as the tibial sesamoid position (TSP).
A recent study conducted between February 2007 and November 2011 aimed to investigate the influence of postoperative TSP on the functional outcome and patient satisfaction following hallux valgus surgery. The study involved 250 patients who underwent surgery at a tertiary hospital and were subsequently followed for two years post-surgery.
The patients were divided into two groups based on the TSP classification developed by Hardy and Clapham. This classification system grades the TSP from I to VII, with grades I to IV considered normal and grades V to VII considered outliers. The grading was determined using postoperative weight-bearing anteroposterior (AP) radiographs.
The results of the study showed a significant improvement in the TSP from grade VII preoperatively to grade IV postoperatively. This improvement was associated with better functional outcomes and higher patient satisfaction. Specifically, the visual analog scale for pain, a common tool used to measure pain levels, showed a one-point improvement in the normal group compared to the outlier group two years after surgery.
Moreover, the American Orthopaedic Foot & Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale, a measure of foot function, was six points higher in the normal group. This suggests that patients with a postoperative TSP within the normal range experienced less pain and better foot function than those with an outlier TSP.
Interestingly, patients in the outlier group were more likely to express dissatisfaction with the surgery. This suggests that the position of the tibial sesamoid post-surgery can significantly impact patient satisfaction.
Based on these findings, the study recommends correcting the TSP to a grade of IV or less during hallux valgus surgery. This can potentially improve the functional outcome and increase patient satisfaction post-surgery.
In conclusion, the position of the tibial sesamoid is a crucial factor to consider during hallux valgus surgery. Correcting the TSP to a normal range can lead to better functional outcomes and higher patient satisfaction. This study provides valuable insights for podiatric surgeons and can guide surgical strategies for hallux valgus. However, as with all medical procedures, individual patient characteristics and needs should be taken into account when deciding on the most appropriate surgical approach.
