An Innovative Application of a Computer Aided Design and Manufacture Implant for First Metatarsal Phalangeal Joint Arthrodesis: A Case Report.

The definitive treatment to correct the deformity of hallux abducto valgus involves surgical fixation. This pathological condition focuses on combined abnormalities of the first metatarsal phalangeal joint (MPJ), medial progression of the first metatarsal, and lateral deviation of the hallux. In most known literature described to date, a computer aided design/manufacture implant has not yet been reported as a viable salvage tool used as an inter-positional structural implant for a first MPJ arthrodesis. The fundamentals of this salvage procedure are to restore anatomical length of the first ray, furnish continuity to the forefoot parabola, administer a robust inter-positional implantTM (Additive Orthopaedics, Little Silver, NJ) of optimal strength, and provide biomechanical reclamation of the tripod foot. This case study describes a procedural technique that required a 2-stage surgical approach consisting of primary external fixation with a SideKickTMCoreTrackTM (Wright Medical, Memphis, TN) tube fixator monorail to expand soft tissues for approximately 1 month.  Followed by a secondary procedure utilizing BioCUE® (Biomet Orthopaedics, Warsaw, Indiana) Bone Marrow Aspiration Concentration system, Augment® Injectable (Wright Medical, Memphis, TN), and custom GAME PLANTM (Additive Orthopaedics, Little Silver, NJ) Technology with computer assisted design/manufacture first MPJ inter-positional caged implantTM arthrodesis.  We present the case of a 46-y-old active female who suffered avascular necrosis of her left foot first metatarsal head from a previous Austin bunionectomy correctional procedure.

Schwannoma of the plantarmedial aspect of the foot: A case report.

Schwannomas of the common medial plantar nerve branch are rare solitary nerve sheath tumors. Fewer than a dozen cases have since been described in the literature, most of which were initially misdiagnosed as ganglion cysts. The case of a 56-year-old male who developed a painful mass on the plantar medial hallux, misdiagnosed as a ganglion cyst, is presented. After surgical intervention and pathological analysis the patient was diagnosed as having a schwannoma. A schwannoma is a slowly growing neoplasm of Schwann cell origin. It is very rare for a schwannoma to transform into a malignant lesion and usually occurs in individuals between the ages for 20-50. Schwannomas usually have a predilection for the head and upper extremities and is very rare in the foot and ankle. The principal treatment of a schwannoma is surgical excision, which eliminates symptoms and can correctly diagnose the mass. Even though schwannomas of the foot have been reported in literature, this case demonstrates an abnormal location on a branch of the medial plantar nerve. Level of Clinical Evidence: Level 4 of Evidence.

A Formal Work Hour Analysis of the Resident Foot and Ankle Surgeon.

As new documentation requirements by governments and third-party payees increasingly occupy physicians' time, duty hour restrictions have continued to restrict the work hours of residents, leaving programs tasked to produce proficient foot and ankle surgeons (FASs) in less time. The purpose of the present study was to quantify the workday of resident FASs at our institution to identify areas suited for revision to improve efficiency and training. A resident from each postgraduate year (PGY) was recruited and consented for minute-to-minute observation by 4 independent observers over 5 consecutive workdays. The time recorded was placed into a predefined work model consisting of 9 categories (education, research, operating room, patient care, documentation/administration, communications, transit, basic needs, and standby) within 1 of 3 value groups (positive, neutral, or negative). A fifth independent observer reviewed and recorded all collected data. Over 5 consecutive days, ancillary staff frequently disrupted the PGY-1 resident's workflow. The interruptions fragmented the resident's thoughts, increased inefficiency, and resulted in the largest proportion of the resident's time (16.7%) being occupied by documentation/administration duties. For the PGY-2 and PGY-3 residents, unexpected trends in standby were identified during the preoperative period. Secondary analysis revealed that during unexpected preoperative delays, resident efficiency was poor. To maximize efficiency and improve training, residents must increase their awareness of self-inefficiency while minimizing unnecessary interruptions and the time occupied by duties of lesser value. It is our hope that the present study will aid other institutions in facilitating similar improvements to the education and training of our fellow resident FASs.

Patient-Perceived Recovery and Outcomes After Silastic Implant Arthroplasty.

In some chronic musculoskeletal conditions, patients with persistent pain and disability have still achieved recovery through behavioral adaptations (readjustment) or cognitive coping (redefinition). Although the pendulum shift from physician-reported clinical indicators to patient-reported outcomes measures (PROMs) has recently focused on quantifying residual pain and disability to determine recovery (resolution), whether patients are capable of coping with any ongoing deficits and achieving other forms of recovery has not been considered. We performed a retrospective case series to assess patient-perceived recovery and outcomes after silastic implant arthroplasty for hallux rigidus. From July 2006 to July 2016, 28 patients at a single institution were enrolled. PROMs were prospectively obtained and compared between patients considering themselves recovered without or with residual deficits (recovered-resolved, recovered-not resolved) and those not recovered. Holistic satisfaction, procedure-specific satisfaction, complications, reoperations, and failure rates were recorded. Overall, 50.0% perceived themselves as recovered-resolved, 43% as recovered-not resolved, and 7% as not recovered. The mean modified Foot Function Index was 17.26, the verbal analog scale for pain score was 2.03, and implant survivorship 100% at a median of 67 (interquartile range 28.4 to 103.5) months. Although only 50% of patients reported complete symptom resolution, satisfaction was high, and most perceived themselves as recovered, suggesting recovery in hallux rigidus might not always be predicated by the complete resolution of all symptomatology. Although PROMs relying on pain inference and functional disability will continue to be utilized with increasing frequency, foot and ankle surgeons should be cognizant of their inherent limitations in assessing other forms of recovery.

Publication Rates for Oral Manuscript and Poster Presentations From the American College of Foot and Ankle Surgeons: 2010 to 2014.

The American College of Foot and Ankle Surgeons (ACFAS) annual conference has served as a premiere platform to disseminate the latest innovations and research in the field of foot and ankle surgery. The quality of national society conferences is often assessed indirectly by analyzing the the journal publication rate of the abstracts presented. The purpose of this retrospective study was to assess the journal publication rate for abstracts (oral manuscripts and posters) accepted for presentation at the ACFAS conference from 2010 to 2014. All accepted abstracts from this period were compiled by the ACFAS office. PubMed, Google Scholar, and Scopus searches were performed using abstract titles and author names. Overall, the journal publication rate was 76.9% (83 of 108) for oral manuscripts and 23.2% (258 of 1113) for poster abstracts. The mean time to publication was 9.6 (range 0 to 44) months and 19.8 (range 0 to 66) months for oral and poster abstracts, respectively. The most common journal for abstract publication was The Journal of Foot and Ankle Surgery. Notably, the ACFAS oral manuscript publication rate from 2010 to 2014 (76.9%) exceeded its previously reported rate from 1999 to 2008 (67.5%) and the American Orthopaedic Foot and Ankle Society podium publication rate from 2008 to 2012 (73.7%). To the best of our knowledge, the publication incidence for oral abstracts presented at the ACFAS conference is now the highest reported of any national foot and ankle society conference to date.
