Patients Who Undergo Primary Lumbar Spine Fusion After Recent but Not Remote Total Hip Arthroplasty Are at Increased Risk for Complications, Revision Surgery, and Prolonged Opioid Use.

OBJECTIVE: To evaluate the effect of a recent history of total hip arthroplasty (THA) on primary lumbar spine fusion (LSF) for concurrent hip and spine disease. METHODS: A total of 98,242 patient records from the PearlDiver Database were evaluated and divided into 3 cohorts: 1) patients with a history of LSF alone, 2) patients with a history of LSF for newly diagnosed lumbar disease after having a remote THA> 2 years previously, and 3) patients with a history of LSF after having recent THA <2 years before LSF who initially presented with concurrent hip and lumbar spine disease and underwent THA before LSF. Postoperative outcomes were assessed with multivariable logistic regression to determine the effect of THA on outcomes after LSF with respect to postoperative complications, LSF revision rates, and opioid use. RESULTS: Patients who had LSF after a recent THA had increased risk of deep venous thrombosis (adjusted odds ratio [aOR], 1.39; P = 0.0191), neurologic complications (aOR, 1.81; P = 0.0459), prolonged opioid use (aOR, 1.22; P = 0.0032), and revision LSF (12.8%; P = 0.0004 vs. 9.9%; OR, 1.41; P < 0.0001; hazard ratio, 1.69; P < 0.0001). Patients who underwent LSF after a remote history of THA had no significant difference in DVT (4.2% vs. 2.6%, aOR, 1.31; P = 0.2190), neurologic complications (1.0% vs. 0.5%, aOR, 2.02; P = 0.1220), revision surgery (9.6% vs. 9.9%, aOR, 1.06; P = 0.7197), or prolonged opioid use (36.5% vs. 24.4%, aOR, 1.17; P = 0.1120). CONCLUSIONS: Patients who undergo LSF with a history of THA may be at increased risk of postoperative complications, revision LSF, and prolonged opioid use if their THA was performed for concurrent hip-spine disease in the recent past (<2 years).
