Impact of Low Social Support Systems on Post-Operative Outcomes of Ankle, Hindfoot and Midfoot Surgery

CATEGORY: Other; Hindfoot; Midfoot/Forefoot; Trauma INTRODUCTION/PURPOSE: Degenerative conditions of the ankle, hindfoot and midfoot can markedly limit mobility, and functional disability due to bone and joint pathology has been demonstrated to predict mortality, and in some cases, decrease life expectancy by up to 10 years. Optimizing outcomes in surgical treatment of these conditions is therefore essential and requires analysis of both medical interventions and psychosocial factors. Physicians have only recently begun to identify social support to be a key factor in post-operative functional ability, though our understanding of their impact on surgical outcomes is limited. The purpose of this study was to elucidate the link between low social support and postoperative surgical foot and ankle outcomes. METHODS: A single-center, prospective study was conducted on patients who underwent elective or non-elective ankle, hindfoot, or midfoot surgery between 2015 and 2019. Patients who were pre-operatively and post-operatively assessed at 6 month or 1 year follow up using the Short Form Health Survey (SF-36), Life-Space Assessment survey (LSA), and/or visual analog scale (VAS) for pain were administered a social support survey scoring the individuals social support system. Patient reported outcomes were compared between low social support patients (score <= 13) and high social support patients (score > 13). RESULTS: Preoperative baseline and 6 month LSA scores in the low social support group were significantly lower compared to the normal social support group (P = 0.044, P = 0.038), a trend not observed at the 1 year post-operative mark. Low social support pre-operative SF-36 MCS scores (P = 0.015) were significantly lower than the high social support group with no difference detected in pre-operative SF-36 PCS scoring. At 6-month follow-up, the low social support group had significantly lower SF-36 PCS scores (P = 0.031) and SF-36 MCS scores (P = 0.006) compared to the high social support group. At 1 year follow up, these differences in PCS (P = 0.04) and MCS (P= 0.007) persisted. No significant differences in VAS scores were observed. CONCLUSION: Among adults undergoing foot and ankle surgery, low perceived social support was associated with lower degrees of perceived mental well-being and physical wellbeing up to 1 year postoperatively.
