[PMID: 38601890 PMCID: PMC11002844 DOI: 10.1016/j.jor.2024.03.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 03/12/2024] [Indexed: 04/12/2024] Open
Abstract
Introduction The advantages of outpatient surgery have been shown in other orthopedic subspecialities to be a means of driving down costs and reducing the average length of hospital stay. However, there is a scarcity of literature examining the utility of a specific, hospital-based facility performing such procedures for limb lengthening. Considering this, we aimed to investigate surgical factors, patient characteristics, and the incidence of outpatient postoperative complications for patients undergoing surgery and subsequent distraction osteogenesis utilizing the Precice® nail, a state-of-the-art magnetic intramedullary nail (MILN). Methods We performed a retrospective review of medical records pertaining to outpatient limb lengthening procedures occurring between January 2012 and September 2023 at a single institution, as performed by three surgeons. Variables of interest included baseline demographics, type of anesthesia, operative bone, laterality, preoperative diagnosis, osteotomy level, procedure performed, prosthesis, point of entry, nail diameter/length, goal length, goal achieved, postoperative complications, and elective nail removal. Results The cohort comprised 20 limbs, with an average age at index surgery of 24.8 (SD 7.96). There were no complications related to the outpatient nature of the procedure. Five of the 20 limbs had postoperative complications, including deep vein thrombosis (DVT), screw backout, and nail breakage. Conclusion Our initial investigation of outpatient limb lengthening at a specific, hospital-based facility demonstrated favorable postoperative outcomes for those patients undergoing limb lengthening procedures with an MILN. The field would certainly benefit from future research assessing outcomes of pediatric surgeries in the outpatient setting on a larger scale, as well as across hospital systems, the country, and globally. With the proven advances and benefits of MILNs, prioritizing examination of their efficacy in an outpatient population is imperative. Furthermore, the success of outpatient procedures in other orthopedic subspecialities, such as total joint arthroplasty, is a logical, driving precedent for this rationale.

Limb Lengthening and Reconstruction Society orthopedic surgeons in the United States: An analysis of geographical distribution, academic, leadership, and demographic characteristics. World J Orthop 2024; 15:147-155. [PMID: 38464353 PMCID: PMC10921176 DOI: 10.5312/wjo.v15.i2.147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/25/2023] [Accepted: 01/19/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND The Limb Lengthening and Reconstruction Society (LLRS) is a premier orthopedic specialty organization that promotes limb reconstruction for all ages. LLRS membership characteristics, however, are poorly reported. This study delineates orthopedic surgeon LLRS members' demographic traits, academic achievement, leadership attainment, and geographical distribution across the United States. AIM To inform aspiring orthopedic professionals, as well as to promote growth and diversity in both the LLRS organization and overarching field. METHODS This cross-sectional study examined United States LLRS members' academic, leadership, demographic, and geographical attributes. After reviewing the 2023 LLRS member directory, Google search results were matched to the listings and appended to the compiled data. Sex and ethnicity were evaluated visually utilizing retrieved images. The Hirsch index (H-index) of academic activity, residency and fellowship training, other graduate degrees, leadership positions, practice type (academic or non-academic), and spoken languages were categorized. LLRS members per state and capita determined geographic distribution. The Mann-Whitney U test was applied to compare H-index between males and females, as well as to assess member differences pertaining to affiliation with academic vs non-academic practice facilities. RESULTS The study included 101 orthopedic surgeons, 78 (77.23%) Caucasian and 23 (22.77%) non-Caucasian, 79 (78.22%) male and 22 (21.78%) female. Surgeons with DO degrees comprised only 3.96% (4) of the cohort, while the vast majority held MDs [96.04% (97)]. Mean H-index was 10.55, with male surgeons having a significantly higher score (P = 0.002). Most orthopedic surgeons (88.12%,) practiced in academic centers. Of those professionals who occupied leadership positions, 14% were women, while 86% were men. Additionally, 19 (37.25%) United States regions and the District of Columbia lacked an LLRS-member orthopedic surgeon. Total per capita rate across the United States was 0.30 LLRS orthopedic surgeons per 1 million people. CONCLUSION Over 21% of LLRS members are women, surpassing prior benchmarks noted in orthopedic faculty reporting. LLRS members' high research productivity scores imply field dedication that can refine expertise in the limb lengthening and reconstruction space. Gender disparities in leadership remain, however, necessitating greater equity efforts. A low rate of LLRS representation per capita must be addressed geographically as well, to affect improvements in regional care access. This study can serve to support aspiring orthopedic professionals, inform diversity, leadership, and field advancement strategies, and maintain the continued goal of enhanced patient care worldwide.

Nonunion of the femoral shaft associated with limb shortening treated with a combined technique of external fixation over an intramedullary nail versus the Ilizarov method. Arch Orthop Trauma Surg 2022; 142:2185-2192. [PMID: 33651147 DOI: 10.1007/s00402-021-03804-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Accepted: 01/25/2021] [Indexed: 10/22/2022]
Abstract
INTRODUCTION Post-traumatic nonunion of the femur remains a challenging problem even for experienced orthopedic surgeons. The main question is the choice of the optimal surgical tool. MATERIALS AND METHODS Management of 20 patients with nonunion of the femoral diaphysis associated with anatomical shortening was retrospectively analyzed. Group A (n = 14) was treated with a hybrid technique that combined the Ilizarov external fixation and intramedullary nailing. The Ilizarov bone transport was used in group B (n = 6). Patients of both groups had aseptic post-traumatic nonunion. Mean shortening was 4.5 ± 0.4 cm in group A and 4.8 ± 1.0 cm in group B (p = 0.459959). RESULTS Union was achieved in 85.7% of group A and 100% of group B patients. External fixation was repeated in two cases of group A and achieved consolidation. Deep infection developed in one case of group A after 15 months post-frame with the nail in. It was resolved by nail removal, surgical debridement and external fixation. Limb shortening was fully eliminated in eleven cases of group A and four patients of group B. The average duration of distraction was 35.3 ± 1.7 days in group A and 47.8 ± 9.3 days in group B. The total duration of external fixation was 49.1 ± 3.5 and 177.2 ± 21.9 days with an external fixation index of 13.1 ± 1.2 and 52.4 ± 6.4 days/cm, respectively. Distraction regenerate consolidated in all the cases. CONCLUSION Hybrid technique provides bone union with compensation of limb shortening and reduces the treatment period as compared with the Ilizarov method used alone. However, deep infection may happen.

Abstract
Background Lower limb loss is a highly disabling medical condition that can severely impact a person’s quality of life. Recovery becomes especially challenging if an amputee has a short residual limb, which can complicate proper prosthetic fitting, causing discomfort, difficulties in suspension, and reduced mobility. Current limb lengthening techniques such as the Ilizarov apparatus and external fixators are cumbersome, uncomfortable, and have high complication rates. In this study, we investigated the effectiveness of a novel limb-lengthening device that uses intramedullary bone lengthening and requires only one percutaneous rod at the end of the limb during the distraction phase. Only the intramedullary nail remains after the distraction phase, and no external components are required during the consolidation phase. We hypothesize that this system would create a much easier experience for the patient. Methods The system was first tested in a mock surgical implantation using plastic femur bones. The device was then tested in a series of cadaveric experiments using pelvis-to-knee specimens by a group of surgeons. Surgeons evaluated the surgical insertion technique, soft tissue considerations, hardware fixation strategies, and the effectiveness of the distraction mechanism. Revisions and improvements to the device and surgical procedure were made based on the results from the cadaveric experiments. Results A questionnaire was given to two visiting surgeons following the final iteration of the device. The surgeons reported that the system effectively lengthened the limb, was sturdy, and could be installed efficiently. However, there remains a risk of infection and soft tissue imbalances, similar to that introduced by an external fixator device. Suggestions on how to improve the design of the device and mitigate infection through postoperative management and surgical standard of care will be considered for future clinical trials. Conclusions The described intramedullary residual limb-lengthening device has evolved from a prototype to a mature model tested in six cadaveric experiments to date. Further mechanical and functional testing is needed to finalize the device before testing in patients.
