Courtney D Bell, Mark B Wagner, Lian Wang, Kenneth R Gundle, Lloyd E Heller, Hanne A Gehling, Paul J Duwelius,

BACKGROUND:Iliopsoas impingement after total hip arthroplasty (THA) occurs in up to 4.3% of patients resulting in functional groin pain. Operative treatment historically has included open iliopsoas tenotomy or acetabulum revision. We present a large single surgeon series of patients treated with endoscopic iliopsoas tenotomy for iliopsoas impingement after THA to ... Read more >>

Impact of Anterior vs Posterior Approach for Total Hip Arthroplasty on Post-Acute Care Service Utilization.

Coles E L'Hommedieu, James J Gera, Gerald Rupp, Jeffery W Salin, John S Cox, Paul J Duwelius,

Controversy exists as to which surgical approach is best for total hip arthroplasty (THA). Previous studies suggested that the tissue-sparing anterior approach should result in a more rapid recovery requiring fewer postacute services, ultimately decreasing overall episodic cost. The purpose of this cross-sectional study was to determine if any significant ... Read more >>

Geriatric trauma: the role of immediate arthroplasty.

Andrew H Schmidt, Jonathan P Braman, Paul J Duwelius, Michael D McKee,

Periarticular fractures in elderly patients are challenging to manage because the fractures are typically comminuted and the bone is osteopenic, which often result in the failure of internal fixation. Patients who sustain these fractures demand immediate mobilization or they often do not recover their preinjury level of function. In geriatric ... Read more >>
