The Effects of NSAIDs on Foot and Ankle Arthrodesis Procedures, A Retrospective Chart Review

The opioid epidemic has forced practitioners to look to other means for pain control. This has made non-steroidal anti-inflammatory medications (NSAIDs) much more prevalent. Advantageous as it might seem, a closer look at the pharmacodynamics shows that by inhibiting COX enzymes, NSAIDs are inhibiting prostaglandin which could inhibit bone healing. Our objective is to determine if NSAID use during foot and ankle arthrodesis inhibits bone healing. We reviewed the electronic database of patients who underwent foot and/or ankle arthrodesis with the inclusion criteria of fusion CPT codes. Exclusion was younger than 18 years old, active infection, revisional arthrodesis, less than 3 months follow-up at Phoenix VA Healthcare System, no postoperative radiographs available, and death prior to fusion. One-hundred and sixty-one procedures in 155 patients were included and split into 2 groups. Group 1 included patients without non-union (n = 122) and Group 2, included patients with non-union (n = 39). NSAID use presented in 40 (33%) of procedures in Group 1 compared to 11 (28%) of procedures in Group 2 (Table 2). The mean days on NSAIDs was 51.2 ± 36.1 days in Group 1 compared to 52.2 ± 51.2 days in Group 2 with no statistical difference between groups. Time to fusion was longest in patients on NSAIDs (110 days) or both NSAIDs and active Tobacco use (114 days) and shortest in patients on active Tobacco (93 days) or no NSAIDS and tobacco use (93.61 days). NSAID use did not appear to affect ability to obtain joint fusion, but does appear to delay time to fusion.

May-Thurner Syndrome in Operative Ankle Fracture Dislocations: A Case Report

May-Thurner syndrome (MTS) is a rare condition in which patients develop iliofemoral deep venous thrombosis owing to an anatomic variant in which the right common iliac artery overlies and compresses the left common iliac vein against the lumbar spine. Data regarding lower extremity trauma in patients with previously diagnosed MTS are rare. We discuss the operative approach for ankle trauma occurring 3 weeks after endovascular surgery for the treatment of MTS.

Accuracy and Reliability of Postoperative Radiographic Evaluation of First Metatarsal-Phalangeal Joint Arthrodesis

The clinical value of routine postoperative radiographic evaluation after orthopedic procedures has recently been called into question. The objective of the present investigation was to evaluate the ability of foot and ankle surgeons to accurately and reliably assess postoperative radiographs after first metatarsal-phalangeal joint arthrodesis. Thirty sets of digital radiographs from 11 patients who had undergone first metatarsal-phalangeal joint arthrodesis were retrospectively evaluated by 5 podiatric physicians board-certified in foot surgery. The surgeons were asked to answer several questions, including whether the radiograph appeared to be >4 or <4 postoperative weeks; whether the radiograph appeared to be >8 or <8 postoperative weeks; their estimation of the postoperative week; and whether they would allow the patient to begin weightbearing based on the radiographic findings. With respect to whether the radiographs were >4 or <4 postoperative weeks, surgeons made accurate assessments 63.33% of the time (95 of 150; range 56.67% to 73.33%), with a kappa of 0.220. With respect to whether the radiographs were >8 or <8 postoperative weeks, surgeons made accurate assessments 60.0% of the time (90 of 150; range 53.33% to 70.0%), with a kappa of 0.203. With respect to the estimation of the postoperative week of the radiograph, surgeons accurately assessed the radiographs within a 4-week period 34.0% of the time (54 of 150; range 26.67% to 46.67%), with a kappa of 0.425. With respect to allowing the patient to bear weight according to the radiographic findings, the surgeons were in complete agreement 26.67% of the time (8 of 30), with a kappa of 0.251. These results provide evidence against the serial routine use of postoperative radiographs for the first metatarsal-phalangeal joint arthrodesis in the absence of a specific clinical indication.

An Alternative Surgical Approach to Pseudoainhum: A Case Report

Pseudoainhum is a disorder of unknown etiology that is usually congenital and nonprogressive. One theory states it is caused by amnion band constriction in utero. These constriction bands lead, not only to a less cosmetically appealing foot, but also to long-term neurovascular compromise, resulting in amputation of the digit. The described surgical approaches have been limited within published data. The 2 procedures that have been described are either a Z-plasty or amputation, depending on the degree of the deformity. The present case report provides an alternative surgical approach to a pseudoainhum deformity of a third digit.

Assessment of Anatomic Risk During Syndesmotic Stabilization With the Suture Button Technique

The suture button technique represents an accepted method of fixation for acute or chronic injury to the tibiofibular syndesmosis. The objective of the present investigation was to assess the anatomic risk to the superficial medial neurovascular structure with insertion of a syndesmotic suture button and to measure the distance of the button to the greater saphenous vein during a standardized insertion. A syndesmotic suture button was inserted with a standardized technique in 20 fresh frozen cadaveric limbs. Of 20 suture buttons, 14 (70.0%) were inserted posterior to the greater saphenous vein, 2 (10.0%) were inserted anterior to the greater saphenous vein, and 4 (20.0%) were inserted directly onto the greater saphenous vein. A total of 11 suture buttons (55.0%) were inserted with some entrapment of a medial neurovascular structure. The absolute mean ± standard deviation distance of the suture button to the greater saphenous vein was 4.88 ± 4.44 mm. The results of the present investigation have indicated that a risk of entrapment of superficial medial neurovascular structures exists with insertion of a suture button for syndesmotic fixation and that a medial incision should be used to ensure that structures are not entrapped.
