Application of Nice knot technique in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures

To explore the effectiveness of Nice knot technique for wound closure in Gustilo type ⅢA and ⅢB open tibial fractures. A retrospective study was performed on 22 patients with Gustilo type ⅢA and ⅢB open tibial fractures, who underwent wound closure using the Nice knot technique and were admitted between June 2021 and June 2022. There were 15 males and 7 females. The age ranged from 18 to 67 years, with an average of 41.9 years. The causes of injury included traffic accident in 11 cases, falling from height in 7 cases, and heavy object injuries in 4 cases. Fractures were located on the left side in 9 cases and on the right side in 13 cases. And 9 cases were type ⅢA fractures and 13 were type ⅢB fractures according to Gustilo classification. All patients had extensive soft tissue injuries, and no vascular or neurological damage was observed. The time from injury to debridement was 3-8 hours (mean, 6.5 hours). The sizes of wounds before operation and at 2 weeks after operation were measured and wound healing rate at 2 weeks after operation were calculated. The wound healing time and wound healing grading were recorded. The Vancouver Scar Scale (VSS) score was used to assess the wound scar after wound healed and the excellent and good rate was calculated. The wound area was 21.0-180.0 cm 2 (mean, 57.82 cm 2) before operation, and it was 1.2-27.0 cm 2 (mean, 6.57 cm 2) at 2 weeks after operation. The wound healing rate at 2 weeks after operation was 76%-98% (mean, 88.6%). After operation, 2 cases needed to adjust Nice knot due to skin cutting and 1 case occurred soft tissue infection on the wound. The other patient's wounds healed. The average wound healing time was 27.8 days (range, 18-44 days). And the wound healing were grade A in 13 cases and grade B in 9 cases. VSS score was 2-9, with an average of 4.1; 10 cases were rated as excellent, 10 as good, and 2 as poor, with an excellent and good rate of 90.9%. All patients were followed up 9-24 months (mean, 14.6 months). During follow-up, no deep infection or osteomyelitis occurred. Two cases experienced fracture non-union, and were treated with compression fixation and bone grafting. The fractures of the other patients all healed, with a healing time of 85-190 days (mean, 148.2 days). Nice knot technique can be used in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures effectively, which is easy to operate.

IS POOLING OF DATA POSSIBLE IN STUDIES EVALUATING OPEN TIBIAL SHAFT FRACTURES REQUIRING FLAP COVERAGE?

The aim of this study was to perform a systematic review of the literature on Gustilo-Anderson (GA) type IIIB open tibial shaft (AO-42) injuries to determine the consistency of reporting in the literature.A search of PubMed, EMBASE and Cochrane Central Register of Controlled Trials was performed to identify relevant studies published from January 2000 to January 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The study was registered using the PROSPERO International prospective register of systematic reviews. Patient/injury demographics, management and outcome reporting were recorded.There were 32 studies that met the inclusion criteria with a total of 1,947 patients (70.3% male, 29.7% female). There were 6 studies (18.8%) studies that reported on comorbidities and smoking, with mechanism of injury reported in 22 (68.8%). No studies reported on all operative criteria included, with only three studies (9.4%) reporting for time to antibiotics, 14 studies (43.8%) for time from injury to debridement and nine studies (28.1%) for time to definitive fixation. All studies reported on the rate of deep infection, with a high proportion documenting union rate (26/32, 81.3%). However, only two studies reported on mortality or on other post-operative complications (2/32, 6.3%). Only 12 studies (37.5%) provided any patient reported outcomes.This study has demonstrated a deficiency and a lack of standardized variable and outcome reporting in the orthopaedic literature for Gustilo-Anderson type IIIB open tibial shaft fractures. We propose a future international collaborative Delphi process is needed to standardize.

Antibiotic bead pouch versus negative pressure wound therapy at initial management of AO/OTA 42 type IIIB open tibia fracture may reduce fracture related infection: A retrospective analysis of 113 patients

IntroductionFracture related infection (FRI) may be a devastating complication of open tibial shaft fractures. We sought to determine if antibiotic bead pouch, negative pressure wound therapy, or negative pressure wound therapy over antibiotic beads as the initial coverage method for type IIIB open tibial shaft fractures is associated with risk of FRI. Patients and methodsRetrospective cohort study with radiograph and chart review of patients aged ≥16 years with isolated, displaced, extra-articular, Gustilo-Anderson type IIIB open diaphyseal AO/OTA 42 tibial fractures requiring rotational or free tissue transfer for soft tissue coverage at one Level 1 trauma center between 2007 and 2020. An association of dressing applied at the first surgical debridement (application of antibiotic bead pouch, negative pressure wound therapy, or combined therapy) with a primary outcome of FRI requiring debridement or amputation was analyzed by multivariable logistic regression considering demographic, injury, and treatment characteristics. Results113 patients met eligibility criteria. Median follow-up was 33 months (interquartile range 5–88). 41 patients were initially treated with NPWT, 59 with ABP, and 13 with ABP+NPWT at the initial surgical debridement. 39 (35%) underwent subsequent debridement or amputation for FRI. One amputation occurred in the ABP group for refractory deep surgical site infection (p = 0.630). Initial wound management with an antibiotic bead pouch versus either negative pressure wound therapy alone or negative pressure wound therapy combined with an antibiotic bead pouch was associated with lower odds of debridement or amputation for FRI (β = -1.08, 95% CI -2.00 to -0.17, p = 0.02). ConclusionsIn our retrospective analysis, antibiotic bead pouch for initial coverage of type IIIB open tibial shaft fractures requiring flap coverage was associated with a lower risk of FRI requiring debridement or amputation than negative pressure wound therapy applied with or without antibiotic beads. A prospective clinical trial is warranted.

Orthoplastic Reconstruction of Type IIIB Open Tibial Shaft Fractures Using Debrided, Devitalized Cortical Segments: Health-Related Quality-of-Life Outcomes.

To determine health-related quality of life (HRQoL) in patients who sustained type IIIB open tibial diaphyseal (OTA/AO-42) fractures and underwent orthoplastic reconstruction using mechanically relevant devitalized bone (ORDB) versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction. Consecutive cohort study. The study included 74 patients who sustained a type IIIB open tibial diaphyseal fracture requiring orthoplastic reconstruction over a 4-year period in a major trauma center. All patients underwent a two-stage orthoplastic reconstruction protocol, with the second stage consisting of definitive fixation and flap coverage (free fascial anterolateral thigh flap) in a single sitting. Patients were contacted at a minimum of 30 months to measure HRQoL. Patients requiring ORDB versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction. The primary outcome measure was HRQoL ascertained using Euro-Qol (EQ)-5D and Short-Form (SF)-36 scores. Thirty (n = 30) patients underwent ORDB with the remaining 44 not requiring devitalized bone as part of their reconstruction. The median age was 46.5 years [interquartile range (IQR) 29.0], with a median follow-up of 3.8 years (IQR 1.5). The median cohort EQ-5D was 0.743 (IQR 0.222), ORDB 0.743 (IQR 0.195) versus non-ORDB 0.748 (IQR 0.285), P = 0.71. The median physical component SF-36 score was 80 (IQR 50), ORDB 80 (IQR 34.5) versus non-ORDB 77.5 (IQR 58.75), P = 0.72. The median mental component SF-36 score was 80 (IQR 28), ORDB 80 (IQR 21) versus non-ORDB 80 (IQR 36), P = 0.29. In patients who sustained a type IIIB open tibial shaft fracture and who underwent a 2-stage orthoplastic reconstruction, ORDB does not seem to be associated with inferior health-related quality of life based on EQ-5D or SF-36 scores. The results of this approach should be considered within the strict combined orthoplastic approach in the study unit. Therapeutic Level III.

Acute Compartment Syndrome in Type IIIB Open Tibial Shaft Fractures Using a 2-Stage Orthoplastic Approach.

To determine the rate of acute compartment syndrome (ACS) in a series of patients with Gustilo-Anderson type IIIB open tibial shaft fractures that were treated using a specific 2-stage orthoplastic protocol. Consecutive cohort study. Ninety-three (n = 93) consecutive patients with a type IIIB open tibial shaft fracture (OTA/AO-42) treated using a 2-stage orthoplastic approach, between August 2015 and January 2018. After exclusions, 83 (n = 83) were eligible for analysis. Colloid resuscitation and 2-stage orthoplastic reconstruction of type IIIB open tibial shaft fracture. Stage 1 consists of "3-vessel view" early debridement and temporary internal fixation, with stage 2 consisting of a single-stage fix and flap. Rate of ACS. Secondary outcomes included early/late sequelae of missed ACS, deep infection, arterial injury, nonunion, and flap failure. Eighty-three (n = 83) patients were included for analysis. The median age was 45.4 years [interquartile range (IQR) 35] with a median follow-up of 1.6 years (IQR 0.8). The median number of operations was 2.0 (IQR 4). For the primary outcome, there were a total of 0 (0/83) patients who required fasciotomy or developed early/late clinical sequelae of missed ACS. Six (6/83, 7.2%) patients developed deep infection, 18 patients (18/83, 21.7%) experienced nonischemic arterial injury, 5 patients (5/83, 6.0%) experienced nonunion, with 4 patients (4/83, 4.8%) experiencing flap failure. Diabetes was the only variable associated with deep infection (P = 0.025) and nonunion (P < 0.001). Patients with type IIIB open tibial shaft fractures treated with colloid resuscitation and a 2-stage orthoplastic protocol, which includes early "3-vessel view" exposure and debridement, do not appear to develop ACS. Furthermore, no sequelae of missed compartment syndrome was observed at final follow-up. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

A novel low-profile external skeletal fixator for type IIIB open tibial fractures: A biomechanical and clinical pilot study.

Although external fixator is standard for managing staged treatment of open tibial fracture, the main disadvantage of this device is too bulky to be tolerated by most patients for longtime use. The purposes of this pilot study were to compare the biomechanical properties of a novel low-profile external fixator (LP-ESF) with a traditional ESF and also to evaluate its performance in patients with Gustilo type IIIb tibial open fractures. A prospective clinical pilot study started from January 2015 to December 2017, and 18 patients with Gustilo type IIIb open tibial fractures underwent the fixation with a novel LP-ESF system. The biomechanical properties of the LP-ESF were compared with the Synthes External Fixation System according to the standard ASTM F1541-02. These patients were divided into two groups according to the size of bony defect. The postoperative clinical outcomes were subsequently collected. The biomechanical properties of the LP-ESF were comparable with those of Synthes External Fixation System and had an improved the axial/torsional stiffness and ultimate strength. In the clinical study, all patients with LP-ESF had fracture union. The duration of application of LP-ESF was 3.5 to 18 months until fracture union. In 10 of 18 patients, their fractures were immobilized with the LP-ESF until bone union, and no pin tract infection and no chronic osteomyelitis were recorded. The 36-Item Short Form Health Survey life quality and health survey were good to excellent in these patients. Notably, the LP-ESF allowed a patient with severe bone and soft-tissue defects to preserve the leg and joints function. In this study, we found that the novel LP-ESFs had improved clinical outcomes. The long-term LP-ESF application seems to be tolerable in our patients. This novel approach permits better controls in deep infection and faster healing of fractures, and thus may provide a viable alternative treatment for Gustilo type IIIb open tibial fractures.

The Impact of Inadequate Soft-tissue Coverage following Severe Open Tibia Fractures in Tanzania.

Background:Managing lower extremity fractures complicated by large soft-tissue defects is challenging for surgeons in low- and middle-income countries, and long-term quality of life (QOL) for these patients is unclear.Methods:We examined QOL, surgical complications, and longitudinal outcomes in 10 patients with Gustilo-Anderson Classification Type IIIB open tibia fractures seen at an orthopedic institute in Tanzania, from December 2015 to March 2017. Patients completed follow-up at 2-, 6-, 12-, 26-, and 52-week time points, and returned for qualitative interviews at 2.5 years. The primary outcome was QOL, as measured using EuroQoL-5D scores and qualitative semi-structured interview responses. The secondary outcome was rate of complication, as defined by reoperation for deep infection or nonunion.Results:Ten patients enrolled in the study and 7 completed 1-year follow-up. All fractures were caused by road traffic accidents and treated by external fixation. No patients received initial soft-tissue (flap) coverage of the wound. All patients developed an infected nonunion. No patients returned to work at 6 weeks, 3 months, or 6 months. EQ-5D index scores at 1 year were poor (0.71 ± 0.09). Interview themes included ongoing medical complications, loss of employment, reduced income, and difficulty with activities of daily living.Conclusions:Patients in low- and middle-income countries with IIIB open tibia fractures not treated with appropriate soft-tissue coverage experience poor QOL, high complication rates, and severe socioeconomic effects as a result of their injuries. These findings illustrate the need for resources and training to build capacity for extremity soft-tissue reconstruction in LMICs.

Combined medial gastrocnemius and hemisoleus flap: a reproducible alternative for open tibial fractures complicated with large or double soft tissue defects.

Utilization of combined local muscle flaps for Gustilo type IIIB open tibial fractures has not been clearly delineated. We describe a combination of medial gastrocnemius and hemisoleus flaps for managing open tibial fractures accompanying large or double soft tissue defects. Twelve patients with Gustilo IIIB open fractures of the tibial shaft with large (9) or double (3) defects were operated on by fracture stabilization and combined medial gastrocnemius and hemisoleus flap coverage. Data were collected on types of implants, types of flaps, union time, postoperative complications, and Puno functional scores. Regarding implants for fixation, an intramedullary nail was used in three patients, plate and screws in five, combined plate and intramedullary nail in one, and definitive external fixation was used in three. Regarding soft tissue coverage, combined medial gastrocnemius and hemisoleus flaps were used in ten patients, combined hemigastrocnemius and hemisoleus in one, and combined medial gastrocnemius and reversed hemisoleus in one. All flaps survived, and all fractures were united with a mean union time of 19.7weeks (range 16-24). Tip necrosis of the hemisoleus flap occurred in two patients. Regarding Puno functional score, one was determined to be excellent, nine was good and two was fair. Combined medial gastrocnemius and hemisoleus flaps are reliable and effective for open tibial fractures complicated with large or double soft tissue defects.

Plate-Assisted Intramedullary Nailing of Gustilo Type IIIB Open Tibial Diaphyseal Fractures: Does Adjunctive Plate Retention Affect Complication Rate?

To investigate the complication rates after use of retained adjunctive plate (RAP) fixation with intramedullary nailing of Gustilo-Anderson type IIIB open tibia fractures, as part of a 2-stage orthoplastic approach. Consecutive cohort study. One hundred and thirty-seven consecutive patients with a Gustilo-Anderson type IIIB open diaphyseal tibia fracture (OTA/AO 42) treated between May 2014 and January 2018. Ninety-eight patients (RAP = 67; non-RAP = 31) met the inclusion criteria and underwent 2-stage reconstruction. All patients were treated using a small fragment adjunctive plate to hold the fracture reduced before intramedullary nailing. At stage 2, the temporary small fragment (in-fix) plate was removed and the site further thoroughly debrided. After this, the fracture is reduced and held with a new small fragment plate to facilitate the definitive intramedullary nailing. This new plate was either retained (RAP) as part of the definitive fixation at second stage or removed before wound coverage. The main outcome measures were reoperation rate, deep infection, nonunion, and flap-related complication. Six patients (6/98, 6.1%) proceeded to nonunion (RAP 5/67, non-RAP 1/31). This was not significant (P = 0.416). Two hundred twelve operations were undertaken, and the median was 2. Sixteen (16/212, 7.5%) complication-related reoperations were undertaken, affecting 8 patients (8/67, 11.9%) in the RAP group. Eight patients (8/98, 8.2%) developed a deep infection (RAP 6/67, non-RAP 2/31). This was not significant (P = 0.674). In the context of an orthoplastic approach, the use of a RAP with definitive intramedullary nailing does not seem to significantly increase the rate of deep infection or nonunion in patients with type IIIB open tibial shaft fractures. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Comparing the performance of different open injury scores in predicting salvage and amputation in type IIIB open tibia fractures.

Various open injury scores have been devised to aid the difficult decision of salvage or amputation following open fractures of the lower limb. Our aim of the study was to compare the performance of mangled extremity severity score (MESS), limb salvage index (LSI), orthopaedic trauma association-open fracture classification (OTA-OFC) and Ganga hospital score (GHS) in our population of type IIIB injuries. A total of 219 patients with 225 type IIIB open fractures of the tibia were studied prospectively between July 2016 and June 2017. The decision of salvage or amputation was taken by a combined consensus of senior orthopaedic and plastic surgeons, blinded to the scores. All four open injury scores were calculated by an independent reviewer following initial debridement. The follow-up period was one to twoyears. After final follow-up, there were 193 (85.7%) successfully salvaged limbs, 19 primary amputations without attempt of debridement (8.4%), three primary delayed amputations within 72hours (1.3%) and six secondary amputations after 72hours from initial debridement (2.7%). Of these, fourpatients died within oneyear and were excluded. All four scores performed well for salvage, while GHS was superior when considering amputation. MESS, LSI and OTA-OFC underscored amputations, since these scoring systems award more points for vascular injuries. There were both salvaged and amputated patients around the threshold value of amputation for all scores, which was only acknowledged by GHS in its unique 'grey zone'. It includes patients who are neither easily salvageable nor definitely requiring amputation. The performance of the GHS was superior to MESS, LSI and OTA-OFC in our study, since it was developed for type IIIB injuries and includes the 'grey zone', where decisions need to be undertaken on a case to case basis. GHS has an improved ability to determine amputation in IIIB open tibia fractures.

Management of Gustilo type IIIB open tibial shaft fractures with limited resources: experience from an African trauma center.

We sought to evaluate the management of Gustilo type IIIB open tibia diaphyseal fractures in an African trauma center with respect to soft tissue defect management and bone union achievement. Functional outcome assessment was the secondary objective. A retrospective review was conducted including patients treated for open tibia fractures requiring flap coverage between 2007 and 2011. As plastic surgeons were lacking in availability, all procedures were performed by orthopedic surgeons trained in completing nonmicrosurgical flap transfers. Twenty-seven patients with a mean age of 36years were included. Although the mean time to debridement was 11h, early infection occurred in 16 (59%) patients. The mean time to flap coverage was 27days. Among the 29 primary local flap transfers performed, only 4 failed. Secondary amputation was required in one patient after flap failure. Bone reconstruction procedures were required in nine patients and were performed after a mean period of 97days. At the mean follow-up time of 13months, 23 (88%) of the 26 remaining fractures had united. There were three septic nonunions and two cases of chronic osteomyelitis. Functional result was negatively influenced by the soft tissue defect area and low-quality flap coverage. To our knowledge, this is the first series reporting flap reconstructions performed by orthopedic surgeons for Gustilo type IIIB tibia fractures in an African hospital. Local pedicled flap transfers permitted the achievement of soft tissue coverage and bone union in most cases. Subsequent bone grafting was required in one-third of the cases.

Orthoplastic reconstruction of type IIIB open tibial fractures retaining debrided devitalized cortical segments

Type IIIB open tibial fractures are devastating high-energy injuries. At initial debridement, the surgeon will often be faced with large bone fragments with tenuous, if any, soft-tissue attachments. Conventionally these are discarded to avoid infection. We aimed to determine if orthoplastic reconstruction using mechanically relevant devitalized bone (ORDB) was associated with an increased infection rate in type IIIB open tibial shaft fractures. This was a consecutive cohort study of 113 patients, who had sustained type IIIB fractures of the tibia following blunt trauma, over a four-year period in a level 1 trauma centre. The median age was 44.3 years (interquartile range (IQR) 28.1 to 65.9) with a median follow-up of 1.7 years (IQR 1.2 to 2.1). There were 73 male patients and 40 female patients. The primary outcome measures were deep infection rate and number of operations. The secondary outcomes were nonunion and flap failure. In all, 44 patients had ORDB as part of their reconstruction, with the remaining 69 not requiring it. Eight out of 113 patients (7.1%) developed a deep infection (ORDB 1/44, non-ORDB 7/69). The median number of operations was two. A total of 16/242 complication-related reoperations were undertaken (6.6%), with 2/16 (12.5%) occurring in the ORDB group. In the setting of an effective orthoplastic approach to type IIIB open diaphyseal tibial fractures, using mechanically relevant debrided devitalized bone fragments in the definitive reconstruction appears to be safe.

The Effects of Timing of Soft Tissue Coverage on Outcomes After Reconstruction of Type IIIB Open Tibia Fractures.

High-energy open fractures of the tibia are frequently associated with tissue loss, wound contamination, and compromised vascularity that often result in amputation. The management of these severe injuries remains a challenge for orthopedic reconstructive surgeons. Studies have compared the timing of soft tissue coverage of Gustilo type IIIB open tibia fractures with associated outcomes such as rate of deep infection, primary union, length of hospitalization, flap failure, and eventual secondary amputation. These studies often highlight better outcomes with specific time domains that are not always attainable at a large tertiary hospital with multi-system trauma patients. Many studies do not account for delayed patient transfers after initial open fracture management elsewhere. This retrospective analysis of the limb salvage outcomes included 140 consecutive patients with Gustilo type IIIB open tibia fractures who presented to the authors' level I trauma center between 2001 and 2014. The authors included patients who required delayed coverage or who were transferred from outside institutions. The majority (77%) were male, and the mean age was 39.4 years. Motor vehicle accidents were the most common cause of injury, and 83% of patients obtained full weight-bearing status with successful limb salvage. Twenty patients had a secondary amputation, with the cause being refractory osteomyelitis in 52%. This study provides guidance on treating a heterogeneous patient population with severe open tibia fractures typically seen in a large tertiary hospital orthopedic trauma service.

Unilateral external fixator as the primary and definitive treatment modality in type IIIB open tibial fractures: A retrospective study

Unilateral external fixator as the primary and definitive treatment modality in type IIIB open tibial fractures: A retrospective study - IJOS- Print ISSN No: - 2395-1354 Online ISSN No:- 2395-1362 Article DOI No:- 10.18231/j.ijos.2019.010, Indian Journal of Orthopaedics Surgery-Indian J Orthop Surg

Management of open tibial fractures type IIIB by segment transfer using limb reconstruction system fixator

Purpose To evaluate the effectiveness of bone transport using limb reconstruction system (LRS) fixator and early coverage in open-type IIIB tibial fractures with massive bone and soft tissue loss. Patients and methods In this study, eight patients with type IIIB open tibial fractures were managed by initial debridement and fixation by LRS uniplanar external fixator. A second-stage rotational myocutaneous flap coverage and osteotomy for segment transfer was done within 14 days. All patients were followed up till full union. Results Full union was achieved in all patients. A total of five patients needed iliac bone graft at the docking site. Union occurred in an average external fixator index of 45.3 days/cm. No flap coverage infection occurred, and there was no significant limb malalignment. Significant limb shortening occurred only in one patient. Conclusion LRS fixator is an effective definitive method for management of open tibial fractures with massive bone loss and soft tissue defects. It is easy to apply, allows early intervention by plastic surgeons to obtain soft tissue coverage, and also allows early patient rehabilitation and joint mobilization.

The Management of Soft Tissue and Bone Loss in Type IIIB and IIIC Pediatric Open Tibia Fractures.

Type III B and C open tibia fractures in children pose a challenge to the orthopaedic surgeon. Limb salvage is the initial goal for the majority of patients, but managing soft-tissue defects and bone loss can be a challenge. The purpose of this study was to evaluate the use of circular external fixation in the management of these injuries. In this retrospective review, we examined children with type IIIB and IIIC open tibial fractures treated with circular external fixation and soft-tissue coverage between 1990 and 2010. Chart review included: mechanism and severity of injury, degree of bone and soft-tissue loss, technique and duration of external fixation, additional procedures, clinical and radiographic outcomes, and complications. Eight patients were identified whose average age at the time of injury was 10.4 years (range, 3.8 to 15.3 y). There were 7 type IIIB and 1 type IIIC fractures. All patients received free or rotational soft-tissue flaps. Average bone loss was 5.4 cm (range, 0 to 12 cm). Three techniques of circular external fixation were used, including: (1) static stabilization to allow for soft-tissue coverage and fracture healing, (2) acute shortening with plan for later limb lengthening, and (3) stabilization of the extremity for soft-tissue coverage and intended bone transport. Seven of 8 limbs were salvaged. Of those 7, all were followed to skeletal maturity and ambulating without assistive devices at final follow-up. Three patients had a clinically relevant leg-length discrepancy (≥2 cm). Four of 8 patients required secondary or contralateral procedures. Pediatric type IIIB and IIIC tibia fractures are limb-threatening injuries that require dynamic thinking and management as the bone and soft-tissue injuries evolve. We have proposed a general algorithm to guide the treatment of these severe injuries. In our experience, circular external fixation, in conjunction with this algorithm, provides the appropriate stability and environment for managing soft tissue and bone loss and can facilitate limb salvage. Level IV.

Predictability of salvage and outcome of Gustilo and Anderson type-IIIA and type-IIIB open tibial fractures using Ganga Hospital Scoring system

Although numerous scoring systems are designed for lower limb open injuries, most of them are based on orthopaedic and vascular injuries and can define only an amputation score. These scoring system lack specificity and sensitivity in predicting the salvage and outcome. Ganga Hospital Scoring system was found to have good specificity in predicting the outcome in Gustilo type-IIIA and type-IIIB injuries.We have validated in our study the Ganga Hospital Scoring system which grades the open injuries based on severity of injury to covering structures, functional and the skeletal units. The score was validated in 40 open injuries of tibia, 11 type-IIIA and 29 type-IIIB. Predictability of salvage and outcome was measured based on this scoring system.Results of our study correlated well with outcome of Ganga hospital study. 38 of 40 limbs with score below 14 and 1 with score above 14 were salvaged. The sensitivity and specificity for the threshold score of 14 was 100% and 95% respectively. Requirement of flaps, number of surgical procedures, time to bony union and infection rates in different groups were similar to original study.The Ganga scoring system was found to have good specificity and sensitivity and reliable in prognosticating the outcome in open injuries of the tibia.

A comparison of primary and delayed wound closure in severe open tibial fractures initially treated with internal fixation and vacuum-assisted wound coverage: A case-controlled study

The ideal timing of wound closure for open tibial fractures is debatable. This study aimed to compare outcomes of primary and delayed wound closure in severe open tibial fractures initially treated with internal fixation and vacuum-assisted wound coverage (VAC). Data of 80 patients with Gustilo–Anderson type IIIA and IIIB open tibial fractures treated with primary internal fixation, VAC, either primary wound closure (PWC) or delayed wound closure (DWC), and external fixation were reviewed retrospectively, and outcomes and complications compared. Patients were divided into three groups, including a PWC group (n = 27), DWC group (n = 22), and a control group (n = 31) that had received external fixation. Among all patients, the median age was 38 years (IRQ 32–47 years), and 67.5% were male. Injuries included 33 Gustilo–Anderson type IIIA and 47 type IIIB. Among injuries, 83% (66/80) were high-energy trauma, 63.8% were contaminated and median injury severity score (ISS) was 14 points. Significant differences were found between groups in fixation methods (p < 0.001). No significant differences were observed between groups in rates of deep infection, osteomyelitis, amputation and nonunion at 6 and 12 months (all p > 0.05), although all rates were markedly lower in the PWC group. The outcomes of PWC performed in conjunction with primary internal fixation and VAC for the treatment of Gustilo–Andersen type IIIA and IIIB open tibial fractures are similar to or better than those of DWC with primary internal fixation and VAC.

Treatment of Type IIIb Open Tibial Fractures

Purpose: The purpose of this study is to evaluate the outcome of treatment for patients with Type IIIb open tibial fractures. Materials and Methods: This study targeted 35 adult patients for whom follow-up was possible over one year after undergoing surgical treatment. There were 29 males and six females with an average age of 45 years. Results: Fracture location was proximal in 10 cases, midshaft in 13 cases, and the distal part of the tibia in 12 cases. An average of 10 days was observed for definitive fixation with soft tissue coverage of the injury. The mean time to radiographic union was 27 weeks. Sixteen cases (45.7%) of complications were observed. Three cases of superficial infection, two cases of deep infection, four cases of partial flap necrosis, three cases of mal-alignment, three cases of joint stiffness, and one case of hardware breakage were observed. The mean lower extremity functional scale score was 68.5 and the factors influencing the clinical results were severity of open wound (p=0.000) and occurrence of complications (p=0.000) according to results of multiple regression analysis. Conclusion: In treatment of Type IIIb open tibial fractures, good clinical results can be expected provided that complications are prevented through proper reduction, firm fixation, early soft tissue reconstruction, and early rehabilitation.

The Gradual Expansion Muscle Flap

High-energy open fractures of the tibia have traditionally been fraught with challenges to include bone comminution or loss, soft tissue loss, nonunion, and infection. A number of techniques have been implemented to treat the severe soft tissue loss typically involving the anteromedial surface of the tibia to include wet-to-dry dressings or Papineau techniques, negative pressure wound therapy, acellular dermal matrices, and rotational or free tissue transfer with Masquelet technique, primary shortening, and distraction osteogenesis to address bone loss. We present a novel technique and subsequent case series that obviates the need of free tissue transfer while treating high-energy type IIIB open tibia fractures by performing an acute shortening and angulation of the tibia and rotational muscle flap coverage and split-thickness skin grafting of the soft tissue defect. Distraction histiogenesis with circular external fixation is then used to correct the residual osseous deformity while stretching the rotational muscle flap.
