Introduction
Open (compound) fractures are injuries in which a soft-tissue wound communicates the fracture site with the external environment, exposing bone and/or fracture hematoma to the outside [1]. They pose a major reconstructive challenge due to the attendant risk of infection, soft-tissue loss, and delayed union. The annual incidence of open long-bone fractures is estimated at around 11.5/100,000 population, with open tibial fractures accounting for a substantial proportion of these injuries; infection rates rise sharply with increasing injury severity, from under 2% in low-grade injuries to approximately 50% in the most severe grade [2].
Historically, staged management – external fixation followed by delayed internal fixation once soft-tissue swelling had settled – was preferred, chiefly to reduce infection risk. Advances in debridement technique, antibiotic prophylaxis, and soft-tissue reconstruction have since supported primary (early) definitive internal fixation, generally within 72 h of injury, as a viable alternative that may reduce hospital stay and accelerate functional recovery without a proportionate rise in infection.
Selecting patients appropriately for early fixation, however, depends on an accurate assessment of injury severity. The Gustilo-Anderson classification, first described in an analysis of over 670 open fractures [3], remains widely used but has recognized limitations – imprecise definitions, interobserver reliability of only about 60%, inability to grade the extent of skeletal and soft-tissue damage within its broad Type IIIB category, and no guidance on limb salvage [4,5]. The Orthopedic Trauma Association classification refined this approach by grading skin, vascular, muscle, contamination, and bone loss separately [6], while the Ganga Hospital Open Injury Score (GHOIS) incorporates skin, bone, and functional-tissue components to guide both salvage decisions and the timing of soft-tissue reconstruction; a total score of ≤9 identifies lower-violence injuries amenable to early definitive treatment [7,8].
Against this background, we undertook a prospective cohort study to evaluate the outcomes of primary definitive internal fixation performed within 72 h of injury in patients with compound fractures selected using GHOIS (≤9), with the objectives of determining the pattern of injury on the basis of GHOIS, treating patients with the early fixation under a standard antibiotic protocol, and following them for fracture union, soft-tissue healing, functional outcome, and complications over 1 year.
Materials and Methods
This prospective cohort study was conducted in a tertiary-care orthopedic center in India over 21 months (March 2023 to November 2024), after obtaining Institutional Ethics Committee approval (147/IEC AMC/MAY 2024) and written informed consent from all participants. This study was conducted in accordance with the World Medical Association Declaration of Helsinki.
All consecutive patients presenting to the casualty department of the hospital with open tibial fractures and a GHOIS ≤9 who fulfilled the predefined eligibility criteria during the study period (March 2023 to November 2024) were considered for inclusion. A total of 140 patients met the inclusion criteria and were enrolled in the study.
Inclusion criteria were as follows: Patients who gave informed consent, with at least 1 year of follow-up, who underwent definitive fixation and wound closure within 72 h of injury, and who had a GHOIS ≤9. Exclusion criteria were as follows: Loss of limb vascularity or Gustilo-Anderson Type IIIC injury; severe soft-tissue injury warranting initial external fixation; refusal of consent; incorrect antibiotic protocol; loss to follow-up; fixation and/or closure beyond 72 h; polytrauma requiring prior intervention from other specialties; associated head injury; and a GHOIS skin or bone sub-score of 5.
Data were collected using a predesigned, semi-structured questionnaire covering demographic details (age, gender, occupation, and tobacco/alcohol use), mechanism, time and place of injury, associated injuries, and GHOIS scoring. At presentation, all wounds were irrigated with 3–5 L of sterile saline and covered with a sterile dressing. Patients then underwent thorough surgical debridement followed by early definitive internal fixation (intramedullary nailing, open reduction and internal fixation with plating, or screw fixation, as indicated) within 72 h of injury. All patients received a standardized antibiotic protocol of injectable piperacillin-tazobactam 4.5 g 3 times daily, metronidazole 500 mg 3 times daily, and amikacin 500 mg twice daily for 5 days, followed by 10–12 days of oral antibiotics. Soft-tissue cover, where required, was individualized (primary split-skin grafting or flap cover) and, when needed, undertaken jointly with the plastic surgery department within the 72-h window.
Postoperatively, patients underwent isometric quadriceps/hamstring strengthening and knee range-of-motion exercises (lower limb) or isometric elbow flexion-extension exercises (upper limb); tibial intramedullary nail dynamization was performed at 16–20 weeks in selected cases at the treating surgeon’s discretion. Patients were followed for 1 year and assessed for time to soft-tissue healing, time to radiological union, hospital stay, complications, and functional outcome, the last graded using the modified criteria of Ketenjian and Sheldon as excellent, good, fair, or poor [9]. Data were summarized as means for continuous variables and as frequencies and percentages for categorical variables.
Results
A total of 140 patients with compound fractures meeting the inclusion criteria were enrolled and followed for 1 year.

| Stiffness | 6 | 4.28 |
| Non-union | 6 | 4.28 |
| Delayed union | 1 | 0.71 |
Infection was the most common complication (16 cases, 11.42%); of these, eight resolved with antibiotics alone while the remaining eight required re-debridement. Stiffness occurred in 6 patients (4.28%) and improved with physiotherapy. Non-union occurred in 6 patients (4.28%) and required revision surgery, while delayed union was seen in a single patient (0.71%). No patient in this series required amputation or died as a result of the injury or its treatment.
Representative case illustrations demonstrating the treatment pathway and outcomes are shown in Fig. 1 and 2.


Discussion
The management of open fractures continues to evolve, balancing the historic caution around infection with growing evidence favoring early definitive stabilization when injury severity is objectively assessed [10,11]. Contemporary guidance recommends antibiotic administration within 60 min of arrival, debridement within 24 h, and soft-tissue coverage within 7 days, with definitive fixation ideally performed within 24–72 h when feasible [10]. The mean time to fixation of 45.8 h in our cohort, following a mean presentation time of 3.82 h after injury, was consistent with this window and reflects timely triage and surgical decision-making.
The demographic profile in this study – predominantly young to middle-aged males injured in road traffic accidents – mirrors most reported open-fracture cohorts, though the reported mean age varies between series: 41.5 years in the cohort of Cullen et al. [12], 49 years in Nishida et al. [13], and 43.8 years in Prabhakaran et al. [14], compared with 37.08 years in the present study, likely reflecting differences in trauma demographics and case mix across populations. The male predominance (60.71%) and road traffic accidents as the leading mechanism (81.42%) in this study are similarly consistent with the pattern reported by Prabhakaran et al. and Azam et al., underscoring high-energy trauma as the principal driver of compound fractures in this age group. [14,15] (Table 6).

The predominance of Gustilo-Anderson Type IIIA and IIIB injuries (67.13% of the cohort) reflects the referral pattern of a tertiary trauma center and is broadly comparable to the case mix reported by Nishida et al., in whom 116 of 117 fractures were Grade IIIA or IIIB [13]. The mean GHOIS of 7.25 in our cohort falls well within the ≤9 threshold that Rajasekaran and Sabapathy identified as denoting lower-violence injury amenable to early soft-tissue reconstruction and definitive fixation, suggesting that the cohort was consistent with the lower-violence injury group described in previous GHOIS literature [7,8].
Intramedullary nailing was the most frequently used fixation method in our series (54.28%), consistent with its established role as a load-sharing, minimally invasive option that preserves periosteal blood supply and permits early mobilization [16,17]. Comparable series report broadly similar fixation choices tailored to the fracture pattern and bone involved [15].
Functional outcomes in our series were favorable, with 64.28% of patients achieving an excellent or good result by the modified Ketenjian and Sheldon criteria [9] – comparable to the 83% (25 of 30) satisfactory-or-better outcomes reported by Prabhakaran et al., in whom outcomes were similarly better for lower-grade injuries and less favorable when the fracture was close to a joint [14]. The mean time to union (28.49 weeks) and infection rate (11.42%) in our cohort were comparable to outcomes reported in previous studies of open tibial fractures treated with internal fixation or external fixation [18]. These findings suggest that, in appropriately selected open fractures, early definitive fixation was associated with acceptable union and infection outcomes. Azam et al. similarly emphasized that meticulous, repeated debridement together with judicious, staged soft-tissue cover and internal fixation shortens hospital stay and improves anatomical and functional recovery without impeding soft-tissue reconstruction – an approach broadly mirrored in our antibiotic and soft-tissue-cover protocol [15]. Jaidev et al. also reported favorable outcomes following primary internal fixation of ballistic open fractures, although their cohort involved a distinct mechanism of injury and substantially earlier fixation than the present study [19]. Infection remained the most frequent complication in our series (11.42%), a rate consistent with the recognized infection risk associated with open fractures [5]. Antibiotic therapy is an established component of open-fracture management [20]. In our cohort, infection was managed successfully with antibiotics or re-debridement in all cases without limb loss. Non-union (4.28%) and stiffness (4.28%) were infrequent and amenable to revision surgery or physiotherapy respectively, while delayed union occurred in only one patient.
Limitations
This study has several limitations. The absence of a concurrent staged-fixation comparator and the single-center, non-randomized cohort design preclude direct comparison with conventional staged fixation and introduce the possibility of selection bias and residual confounding. Although predefined clinical and injury-severity criteria, including GHOIS, were used to select patients for early definitive fixation, treatment suitability was also influenced by injury characteristics and surgeon judgment. The study population was therefore highly selected, comprising open tibial fractures with GHOIS ≤9 and excluding patients with severe soft-tissue injury requiring initial external fixation, vascular compromise or Gustilo-Anderson Type IIIC injury, a GHOIS skin or bone sub-score of 5, polytrauma requiring prior intervention, and delayed fixation or closure; consequently, these findings should not be extrapolated to severe or physiologically unstable open fractures. Although all fractures were tibial, the cohort included different Gustilo-Anderson grades and fracture patterns, and outcomes were not stratified according to fracture pattern or injury severity beyond the overall Gustilo-Anderson and GHOIS distributions. Interobserver reliability of GHOIS was also not assessed. Furthermore, fixation methods and soft-tissue management were heterogeneous and individualized according to fracture characteristics, soft-tissue condition, and surgeon judgment, making it difficult to isolate the independent contribution of fixation timing from the effects of fixation technique and soft-tissue reconstruction. The relatively broad and prolonged antibiotic regimen used in this cohort may also limit generalizability to centers with different antimicrobial protocols, resistance patterns, and stewardship practices. Infection rates were not formally compared across individual Gustilo-Anderson grades or GHOIS categories. Functional outcome was assessed using the modified Ketenjian and Sheldon criteria without a validated patient-reported outcome measure. Statistical analysis was primarily descriptive, without confidence intervals, effect-size estimation, multivariable analysis, or formal subgroup/predictor analysis; therefore, the independent influence of GHOIS, Gustilo-Anderson grade, time to fixation, fixation method, soft-tissue coverage, smoking status, or fracture pattern on infection, union, or functional outcome could not be established. Finally, the requirement for 1-year follow-up may have introduced attrition or survivorship bias if patients with poorer outcomes were less likely to complete long-term follow-up. Given the observational design and multiple co-interventions, the favorable outcomes observed cannot be attributed causally to early definitive fixation alone. Accordingly, the findings should be interpreted as evidence of feasibility and association in a carefully selected cohort rather than comparative effectiveness or proof of superiority, and future multicenter comparative studies are required to determine whether early definitive fixation offers advantages over staged fixation strategies.
Conclusion
Primary definitive internal fixation of open tibial fractures within 72 h of injury, in appropriately selected patients with GHOIS ≤9, was associated with fracture union and good-to-excellent functional outcomes in the majority of patients, with acceptable healing times, hospital stay, and manageable complication rates. These findings support the feasibility of early definitive fixation in selected open tibial fractures but do not establish superiority or relative safety compared with staged fixation. Multicenter prospective comparative studies are required to determine whether early definitive fixation offers advantages over staged fixation strategies.
Clinical Message
Objective severity scoring using GHOIS may help identify appropriately selected open tibial fractures suitable for primary definitive internal fixation within 72 h. In this selected cohort, early definitive fixation was associated with favorable functional recovery and an acceptable complication profile. However, the absence of a staged-fixation comparator precludes conclusions regarding superiority or relative safety, and multicenter comparative studies are required.
