Proximal Metatarsal Osteotomy in Hallux Valgus

In order to obtain an optimal correction of hallux valgus and to prevent its recurrence, the authors have applied a surgical technique which combines a proximal valgus osteotomy of the first metatarsal bone with an excision of the pseudoexostosis and a distal soft tissue plasty at the first metatarsophalangeal joint. The procedure is based on an etiological theory regarding metatarsus primus varus as the primary cause of the deformity, which is in accordance with the opinion of many other authors. The osteotomy corrects the malposition of the first metatarsal bone thereby reducing the deformity and preventing its recurrence. The soft tissue plasty alleviates secondary contractures that prevent a full correction of the big toe. A series of 43 consecutive patients (46 feet) with a follow-up period of 5–44 months and extracted from a total number of 99 operated cases is presented. The result was excellent in 78 per cent, good in 11 per cent and poor in 11 per cent. The reason for a less than excellent result was almost always inadequate correction of the deformity, at the level of the first metatarsal bone, or the big toe, or both.     

Effect of Mechanical Axis Correction on Outcomes of Hallux Valgus Surgery

A new method of mechanical axis planning has recently been suggested to aid in corrective surgery for hallux valgus (HV) deformity, which aims to identify the ideal position for the first metatarsal after correction. We investigated the influence of the mechanical axis angle (MAA) correction on the outcomes of corrective HV surgery. We reviewed 50 radiographs to identify the “normal” MAA range within the population. We also reviewed the medical records of 100 patients who had undergone scarf osteotomy at our institution from January 2011 to December 2013. These patients were segregated into 2 groups according to their postoperative MAA: those within the normal range (normal group) and those outside this range (outlier group). We compared the pre- and postoperative functional scores between the 2 groups using statistical analysis. The normal MAA range within our population was 12.5°?±?0.8° (range 11.0° to 14.3°). We found that the physical component summary score of the short-form 36-item health survey was significantly poorer for the outlier group at 6 and 24 months postoperatively compared with the normal group, although the other postoperative scores were comparable. Surgical correction of the MAA to the normal range of the patient population can be recommended because it provides improved quality of life. However, further studies are required to investigate the influence of MAA planning on other standardized foot and ankle scores.     

Predictors of Patient Satisfaction in Hallux Valgus Surgery

This study aims to analyze a combination of preoperative biodata, radiological parameters, and validated functional scores to determine predictors for patient satisfaction in patients who have undergone Hallux abducto valgus (HAV) surgery at 2 years postoperatively. Data from 288 patients who had undergone HAV surgery and 373 cases were collected between 2007 and 2013. The study group measured the HAV angle (HVA), tibial sesamoid position (TSP), as well as inter-metatarsal angle (IMA) on both pre- and postoperative radiographs for all patients. Clinical outcomes such as the Visual Analogue Scale for pain, the American Orthopaedic Foot and Ankle Society (AOFAS) Hallux Metatarsophalangeal-Interphalangeal Scale (MTP-ITP) Scale, and Short Form 36 Health Survey's physical and mental component scores (PCS and MCS) were captured preoperatively and postoperatively. Univariate analysis was performed first to determine possible predictors of patient satisfaction and the results were then included in a binary logistic regression model. Independent predictors of patient satisfaction include higher preoperative AOFAS (p value = .028, 95% confidence interval [CI] 0.958, 0.998) and the 2 years postoperative AOFAS (p = .001, 95% CI 1.027, 1.114). We also found PCS and MCS scores at 2 years postoperatively to be independent predictors of patient satisfaction (p = .004, 95% CI 1.015, 1.086 and p = .045, 95% CI 1.001, 1.064 respectively). Predictors of patient satisfaction include subjective outcomes such as the AOFAS score and the Short Form 36 composite quality of life scales of PCS and MCS, rather than objective radiological outcomes such as HVA, IMA, and TSP.     

Hallux Valgus Surgery in the Athlete: Current Evidence

Hallux valgus is a common disorder characterized by a medial deviation of the 1st metatarsal, eventually leading to subluxation and pain of the 1st metatarsophalangeal joint. This can inhibit sports activity. Despite being a common forefoot pathology, debate exists regarding the appropriate surgical approach in the athletic population. Paucity in literature exists with reporting of outcomes of 1st metatarsal procedures leading to best outcomes. This review was able to identify 5 studies of surgical correction of hallux valgus in athletes published to date. The aim is to guide the physician in treating athletes with hallux valgus deformity. Currently, the literature supports distal 1st metatarsal osteotomy (Chevron) with a return to activity of approximately 3 months for mild to moderate deformity, and the Ludloff osteotomy for moderate to severe deformity at a slightly slower time frame of return to sports. At best, the Lapidus procedure allows approximately 80% of patients to return to activity. Studies need to document activity level and return to sport in order to help guide treatment.
