The Current State of International Academic Partnerships in Orthopaedic Surgery Between High-Income and Low and Middle-Income Countries: A Systematic Review

Background

Orthopaedic academic partnerships between high-income countries (HICs) and low and middle-income countries (LMICs) are an effective method to increase research and scholarly support. The purpose of this study was to perform a systematic literature review of the current state of partnerships worldwide and assess the quality, quantity, and content of their research output.

Methods

A systematic review was conducted using 4 academic databases: PubMed, MEDLINE, Embase, and CENTRAL. Article eligibility criteria included articles published between January 2017 and 2022, with orthopaedic authors from at least 1 HIC and LMIC. Articles related to global orthopaedic surgery with exclusively HIC or LMIC authors were excluded.

Results

The database search yielded 25,928 articles, and after deduplication, 21,145 articles were included in the screening. After title and abstract screening, 408 articles underwent full-text review for eligibility. The final list of eligible articles for extraction included 310 publications in 127 journals. Published articles increased over time (46 in 2017 to 88 in 2021) and were most commonly published in the Journal of Bone and Joint Surgery (20, 6.5%). Open-access articles (203, 65.5%) had a significantly greater Journal Citation Indicator (p = 0.024) than non-open-access articles. Most studies (40.7%) were observational, with few (3.6%) randomized controlled trials. Orthopaedic trauma (38.1%) was the most common subspecialty, followed by spine (14.8%) and pediatrics (14.2%). Most partnerships were sponsored by North American authors in 65 LMICs, primarily China, India, and the sub-Saharan African region.

Conclusion

This study identified 310 articles published by orthopaedic international academic partnerships in 106 countries over the past 5 years, demonstrating that collaborations between LMIC/HIC partners nearly doubled over the study period. Sixty-five percent of the articles were published in open-access journals.

Medial tab-type fasciocutaneous flap as an alternative for the management of soft tissue defects of the leg

BACKGROUND

Selecting the right technique for lower limb soft tissue reconstruction is a therapeutic challenge. Despite having several reconstruction options, it's important to choose a technique that is effective and with the least possible donor site morbidity.

OBJECTIVE

Demonstrate the therapeutic efficacy of the medial tab flap in soft tissue reconstruction on the leg, compared to conventional flaps.

MATERIALS AND METHODS

Cohort study matched by age. 64 patients with soft tissue defects were selected and according to the intervention divided in: group 1)medial tab flap, and group 2)conventional flaps (sural, soleus, gastrocnemius) followed up to one year postoperatively.

OUTCOME VARIABLES

surgical time in minutes, healing, healing time in days, complications.

RESULTS

The patients who underwent surgery with medial tab flap and with conventional flaps healed completely. The healing time was 16.2±11.2 days in the tab flap and 16.1±11.2 days in conventional flaps, no statistically significant differences were found between the groups (P=.89). The surgical time for tab flaps was 225.2±117.8minutes, and 191.3±117.2minutes for the comparison flaps (P=.65), there were no statistically significant differences. There were no complications in the medial tab flaps.

CONCLUSION

The findings suggest that the medial tab flap technique is as effective as the conventional flap technique, with complete flap survival and healing, and without any major complications in this studied group.

Usefulness of external fixation and reverse Sural fasciocutaneous flap: Treatment of grade III B open tibial fractures in resource-limited settings

PURPOSE

Sierra Leone is a low-income country located on the west coast of Africa where the majority of the population does not have free access to emergency medical and surgical services, the principal cause of open tibia fractures is motorcycle collision. Open fractures of the middle and distal third of the tibial segments, particularly those classified as type III B, represent a challenge for orthopedic surgeons because of the loss of soft tissue coverage. The Reverse Sural Fasciocutaneous Flap (RSFF) has been shown to be an ideal and reproducible option for the treatment of soft tissue defects. The main aim of this study was to demonstrate the experience in Resource Limited Settings (RLS) by means of a short series of the efficacy of using a combination of external fixation and RSFF in the treatment of grade III B open tibia fractures where plastic surgeons were not available.

METHODS

This retrospective, descriptive, and non-experimental study included 8 patients who underwent surgical intervention between September 2020 and September 2021.

RESULTS

The skin defects were of various sizes; the smallest size was 4 × 7 cm, and the biggest size of 12 × 18 cm. We obtained a success rate in seven of the eight cases.

CONCLUSIONS

External fixation and reverse sural fasciocutaneous sural flap are excellent therapeutic options for the treatment of open grade III B diaphyseal and metaphyseal distal tibial fractures.
