Improvement in Back Pain Following Abdominoplasty: Results of a 10-Year, Single-Surgeon Series.

BACKGROUND: Few studies have examined the impact of abdominoplasty on chronic back pain. OBJECTIVES: The aim of this study was to test our hypothesis that patients undergoing abdominoplasty with anterior abdominal wall plication will show significant improvements in back pain and physical function compared with those without plication. METHODS: We utilized Current Procedural Terminology (CPT) codes to identify patients who underwent abdominoplasty with the senior author over a 10-year period. The Oswestry Disability Index (ODI) and the RAND 36-Item Short-Form Health Survey (SF-36) were administered. All patients indicating preoperative back pain were reviewed. RESULTS: Of 338 patients, 143 surveys (42.3%) were returned; 51 patients (35.7%; n = 28 aesthetic, n = 23 massive weight loss) reported preoperative back pain on the ODI. Paired t tests compared overall and strata-specific changes in ODI and SF-36 pre- and postsurgery. Multivariable linear regression models were fitted to model relations between scores and plication, adjusting for presurgery scores and patient variables. There were significant improvements in overall patient cohort in ODI (-15.14), SF-36 physical function (19.92), and pain (17.42) (P < 0.001), as well as when patients were stratified by plication status. However, outcomes between those with plication and those without were not significantly different. CONCLUSIONS: Abdominoplasty with and without anterior abdominal wall plication significantly improves ODI and SF-36 scores relating to physical function and pain, in both aesthetic and massive weight loss patients. Outcomes did not differ based on plication status. All patients with preoperative back pain showed improvement regardless of operation performed, suggesting that abdominoplasty with or without abdominal wall plication improves chronic back pain in this patient population.

The Management of Postsurgical Pyoderma Gangrenosum following Breast Surgery.

Background: Postsurgical pyoderma gangrenosum is a rare condition characterized by ulcerative lesion development at surgical sites. It is frequently misdiagnosed as infection and mismanaged with surgical debridement, which only worsens the condition. Achieving the correct diagnosis is crucial to delivering the appropriate medical therapy. This article presents four clinical cases of postsurgical pyoderma gangrenosum in breast surgery patients, and proposes a work-up schematic to aid in its diagnosis based on literature review and author experience. Methods: Four patients who developed postsurgical pyoderma gangrenosum following breast surgery were identified by chart review at our institution. Results: The cases include two breast reduction patients, an abdominally based breast reconstruction patient, and a breast augmentation patient. The time to diagnosis and treatment varied greatly between the patients, with diagnosis achieved as early as 13 days postoperatively to as late as one year postoperatively. Two of the four patients were initially mismanaged with surgical debridement, and all patients were treated with at least one course of antibiotics for a misdiagnosis of surgical site infection before they were correctly diagnosed. Conclusions: Postsurgical pyoderma gangrenosum is a rare, ulcerative condition that is difficult to diagnose and often mismanaged with surgical debridement. Diagnosis requires a high clinical suspicion and should be considered in patients with ulcerative lesions resistant to antibiotic therapy, in patients who have bilateral lesions with NAC sparring, and in those with systemic inflammatory conditions. Diagnosis is usually delayed, so it is imperative that surgeons keep this diagnosis in mind when treating breast patients with postsurgical wounds.

Passive engineering mechanism enhancement of a flexor digitorum longus tendon transfer procedure.

Standard treatments of adult acquired flatfoot deformity (AAFD) fail to correct associated dysfunction of the posterior tibial tendon (PTT). This study aimed to determine if a novel passive engineering mechanism (PEM) enhanced flexor digitorum longus (FDL) tendon transfer procedure would better restore physiologic PTT function to improve AAFD gait parameters compared to standard treatment. We evaluated the kinetic, pedobarographic, and kinematic effects of a pulley-based PEM-enhancement system utilizing a cadaveric flatfoot model and robotic gait simulator. FDL tendon force, FDL tendon excursion, regional peak plantar pressures, center of pressure, and foot bone/joint motions were quantified. Throughout the stance phase of gait, PEM-enhancement significantly increased FDL tendon forces, resulting in gait cycle medial column unloading, lateral column loading, forefoot adduction, hindfoot inversion, and increased plantar flexion (p < 0.05). This proof-of-concept study demonstrated that an innovative PEM-enhanced FDL tendon transfer procedure better restored physiologic PTT function, resulting in improved correction of the distinctive AAFD gait characteristics-medial column collapse, hindfoot eversion, and forefoot abduction. Clinical significance: Novel PEM-enhancement of a FDL tendon transfer procedure holds promise as a method for improved treatment of AAFD. © 2018 Orthopaedic Research Society.
