Angiographic evaluation of arterial configuration after acute tibial shortening

Avoiding Compartment Syndrome, Vascular Injury, and Neurologic Deficit in Tibial Osteotomy: An Observational Study of 108 Limbs

INTRODUCTION

Tibial deformities are common, but substantial concern may be associated with corrective osteotomy regarding major complications reported in classic literature. Such studies chiefly focused on high tibial osteotomy, with relatively little investigation of other areas and types of deformity. The primary aim of this study was to identify the rate of compartment syndrome, vascular injury, nerve injury, and other major complications after elective tibial osteotomy.

METHODS

One hundred eight tibia osteotomies performed during 2019 to 2021 were evaluated, representing all tibia osteotomies except situations of existing infection. A retrospective chart review was performed to identify patient demographics, surgical indications, anatomic location of osteotomy, fixation used, and complications prompting additional surgery.

RESULTS

The most common osteotomy locations were high tibial osteotomy (35/108 = 32%, 32/35 = 91% medial opening, and 3/35 = 9% medial closing), proximal metaphysis (30/108 = 28%), and diaphysis (32/108 = 30%). The most common fixation was plate and screw (38/108 = 35%) or dynamic frame (36/108 = 33%). Tranexamic acid was administered to 107/108 = 99% of patients and aspirin chemoprophylaxis was used for 83/108 = 86%. A total of 33/34= 97% of anterior compartment prophylactic fasciotomies were performed for diaphyseal or proximal metaphysis osteotomies. No events of compartment syndrome, vascular injury, nerve injury, or pulmonary embolism occurred. One patient required débridement to address infection. Additional surgery for delayed/nonunion occurred for nine segments (8%). Additional surgery for other reasons were performed for 10 segments (9%), none resulting in reduced limb function.

CONCLUSION

Tibial osteotomy can be safely performed for a variety of indications in a diverse range of patients, without a notable risk of the most feared complications of compartment syndrome, vascular injury, and neurologic deficit. Prophylactic fasciotomy and reducing postoperative bleeding using tranexamic acid, along with location-specific safe surgical techniques, may help prevent major complications and thereby facilitate optimized deformity care.

Acute shortening and angulation for complex open fractures: an updated perspective

Reestablishing an intact, healthy soft tissue envelope is a critical step in managing lower extremity injuries, particularly high-grade open tibia fractures. Acute shortening and angulation can be used independently or together to address complex soft tissue injuries, particularly when bone loss is present. These techniques facilitate management of difficult wounds and can be combined with local soft tissue rearrangement or pedicled flaps as needed, avoiding the need for free tissue transfer. After angular deformity correction, adjacent bone loss can be addressed with bone grafting or distraction histogenesis. This article discusses the indications for, surgical technique for, and limitations of acute shortening and angulation for management of open lower extremity fractures.

Pilon fractures: Consensus and controversy

Pilon fractures are complex injuries that require an individualized approach to treatment to avoid complications and achieve good outcomes. Staged open reduction internal fixation remains the gold standard for most cases to achieve anatomic articular reduction while minimizing soft tissue complications and infection. Careful preoperative planning based on computed tomography dictates the surgical approach for reduction. A subset of cases may be amenable to early definitive or provisional open reduction and internal fixation based on fracture pattern. In some cases of severe articular comminution where reconstruction is not possible, primary ankle arthrodesis may be a good alternative.

Acute Shortening for Open Tibial Fractures with Bone and Soft Tissue Defects: Systematic Review of Literature

Introduction

The presence of massive soft tissue loss in open tibial fractures is a challenging problem. Acute limb shortening is an alternative solution in situations where the use of flaps is limited.

Materials and methods

A review was conducted following the Preferred Reported Items for Systematic Reviews and Meta-analyses checklist (PRISMA) guidelines. A complete search of PubMed, EMBASE and MEDLINE was undertaken. Twenty-four articles related to closure of soft tissue defects through acute limb shortening were identified and included in this review.

Results

All report on restoration of limb function without or with minimal residual shortening. The authors note a decrease in the need for microsurgery. The external fixation devices used for deformity correction after closure of the soft tissue defect by acute shortening, angulation and rotation were the Ilizarov apparatus and circular fixator hexapods mainly.

Conclusion

Acute shortening is an alternative to microsurgical techniques. A ring external fixator is useful for restoring limb alignment after closing the soft tissue defect through creating a temporary deformity. The use of circular fixator hexapods can enable accurate correction of complex multicomponent deformities without the need to reassembly of individual correction units.

Analysis of bone transport for ankle arthrodesis as a limb salvage procedure for the treatment of septic pilon fracture nonunion

Septic nonunion of the pilon region with ankle joint infection is challenging for orthopedic surgeons to treat and is associated with a high risk of limb loss. Therefore, the aim of this study was to evaluate the effectiveness of bone transport for ankle arthrodesis in salvaging the limp after septic ankle destruction of the pilon region. We conducted a single-center, retrospective study including 21 patients treated for septic pilon nonunion with accompanying septic ankle destruction via Ilizarov bone transport between 2004 and 2018. In all cases, the complete excision of the nonunion and the resection of the ankle joint were carried out, followed by treating the bone and joint defect with a bone transport into the ankle arthrodesis. In 12/21 patients an additional flap transfer was required due to an accompanying soft tissue lesion. The overall healing and failure rate, final alignment and complications were recorded by the patients’ medical files. The bone-related and functional results were evaluated according to the Association for the Study and Application of Methods of Ilizarov (ASAMI) scoring system and a modified American Orthopedic Foot and Ankle Society (AOFAS) scale. After a mean follow-up of 30.9 ± 15.7 months (range 12–63 months), complete bone and soft tissue healing occurred in 18/21 patients (85.7%). The patients had excellent (5), good (7), fair (4), and poor (3) results based on the ASAMI functional score. Regarding bone stock, 6 patients had excellent, 7 good, and 6 fair results. The modified AOFAS score reached 60.6 ± 18 points (range, 29–86). In total, 33 minor complications and 28 major complications occurred during the study period. In 2 cases, a proximal lower leg amputation was performed due to a persistent infection and free flap necrosis with a large soft tissue defect, whereas in one case, persistent nonunion on the docking side was treated with a carbon orthosis because the patient refused to undergo an additional surgery. Bone transport for ankle arthrodesis offers the possibility of limb salvage after septic ankle destruction of the pilon region, with acceptable bony and functional results. However, a high number of complications and surgical revisions are associated with the treatment of this severe complication after pilon fracture.

Predictors of Reperfusion and 90-day Functional Outcome After Mechanical Thrombectomy for Large Vessel Occlusion Strokes

OBJECTIVES

Whether elderly patients with adverse comorbidities or strong vascular meandering benefit from mechanical thrombectomy to the same degree as patients who participated in the pivotal randomized controlled trials on this procedure (MR CLEAN, ESCAPE, EXTEND-IA, SWIFT PRIME, REVASCAT, DAWN, and DEFUSE 3) remains unknown. We aimed to investigate the predictors of reperfusion and 90-day functional outcome using real-world clinical data, without excluding elderly patients with adverse comorbidities or patients in whom vascular access could not be achieved.

MATERIALS AND METHODS

We retrospectively reviewed consecutive patients with acute ischemic stroke who underwent or in whom mechanical thrombectomy was attempted at Japanese Red Cross Matsue Hospital from April 2015 to June 2020.

RESULTS

Altogether, 111 mechanical thrombectomies in 111 patients (average age 77.2 years) were attempted for acute ischemic stroke. Vascular access was not achieved in 8 (7.2%) cases. In the multivariable analysis, age ≥85 years (odd ratio [OR] 0.191, 95% confidence interval [CI] 0.057-0.641, p = 0.007) and presence of adverse comorbidities (OR 0.265, 95% CI 0.090-0.659, p = 0.016) were associated with failed reperfusion. The diffusion-weighted imaging (DWI)-ASPECT score ≥6 (OR 4.650, 95% CI 1.610-13.40, p = 0.005) was associated with good 90-day functional outcomes. Presence of adverse comorbidities was not a predictor, but it had a relatively strong correlation with poor functional outcome.

CONCLUSIONS

Mechanical thrombectomy in elderly patients should be considered very carefully if they are aged ≥85 years, have low DWI-ASPECT score and have clear evidence of pre-existing adverse comorbidities.

Bone transport versus acute shortening for the management of infected tibial bone defects: a meta-analysis

Background

The treatment for infected tibial bone defects can be a great challenge for the orthopaedic surgeon. This meta-analysis was conducted to compare the safety and efficacy between bone transport (BT) and the acute shortening technique (AST) in the treatment of infected tibial bone defects.

Methods

A literature survey was conducted by searching the PubMed, Web of Science, Cochrane Library, and Embase databases together with the China National Knowledge Infrastructure (CNKI) and the Wanfang database for articles published up to 9 August 2019. The modified Newcastle-Ottawa scale (NOS) was adapted to evaluate the bias and risks in each eligible study. The data of the external fixation index (EFI), bone grafting, bone and functional results, complications, bone union time and characteristics of participants were extracted. RevMan v.5.3 was used to perform relevant statistical analyses. Standard mean difference (SMD) was used for continuous variables and relative risk (RR) for the binary variables. All of the variables included its 95% confidence interval (CI).

Results

Five studies, including a total of 199 patients, were included in the study. Statistical significance was observed in the EFI (SMD = 0.63, 95% CI: 0.25, 1.01, P = 0.001) and bone grafting (RR = 0.26, 95%CI: 0.15, 0.46, P < 0.00001); however, no significance was observed in bone union time (SMD = − 0.02, 95% CI: − 0.39, 0.35, P = 0.92), bone results (RR = 0.97, 95% CI: 0.91, 1.04, P = 0.41), functional results (RR = 0.96, 95% CI: 0.86, 1.08, P = 0.50) and complications (RR = 0.76, 95% CI: 0.41, 1.39, P = 0.37).

Conclusions

AST is preferred from the aspect of minimising the treatment period, whereas BT is superior to AST for reducing bone grafting. Due to the limited number of trials, the meaning of this conclusion should be taken with caution for infected tibial bone defects.

Pilon Fracture: Preventing Complications

Fractures of the distal tibial plafond (ie, pilon) comprise a broad range of injury mechanisms, patient demographics, and soft-tissue and osseous lesions. Patients often present with considerably comminuted fracture patterns and notable soft-tissue compromise. Surgical intervention must be performed with respect for the exceedingly vulnerable soft-tissue envelope and with a properly executed technique. Even with proper timing, favorable host factors, and expert surgical technique, restoration of function and avoidance of complications are not always achievable. Recently validated techniques further diminish the risk of soft-tissue and osseous sepsis. These techniques include early (ie, "immediate") fixation, upgrading, primary arthrodesis, staged sequential posterior and anterior fixation, acute shortening, and transsyndesmotic fibular plating. Proper application of these recently adopted techniques may be instrumental in achieving aseptic union of pilon fractures.

Shortening and Angulation Strategies to Address Composite Bone and Soft Tissue Defects

Gustilo-Anderson IIIB tibial fractures and infected tibial nonunions represent particular challenges for the orthopaedic trauma surgeon. Debridement of dysvascular bone and soft tissues can create composite bone and soft tissue defects. Restoring the soft tissue envelope is a critical step in preventing or treating ongoing infection and in restoring local blood supply. Shortening and angulation techniques, including the gradual expansion muscle flap, rely on distraction histogenesis to address composite bone and soft tissue loss. These strategies can be used to treat large soft tissue defects when flap coverage or free tissue transfer is not available.

Acute Limb Shortening for Major Near and Complete Upper Extremity Amputations with Associated Neurovascular Injury: A Review of the Literature

In the setting a near or complete upper extremity amputations with significant soft tissue loss and neurovascular compromise, upper extremity surgeons are faced with the challenge of limb salvage. There are a multitude of treatment options for managing skeletal and soft tissue injuries including provisional fixation, staged reconstruction, and an acute shortening osteotomy with primary rigid internal fixation. However, many complications are associated with these techniques. Complications of provisional fixation include pin tract infection and loosening, tethering of musculotendinous units, nonunion, and additional surgeries. Staged reconstruction includes a variety of techniques: distraction osteogenesis, bone transport, or vascularized and non-vascularized structural autograft or allograft, but the risks often outweigh the benefits. Risks include nonunion, postoperative vascular complications necessitating reoperation, and the inability to return to the previous level of function at an average of 24 months. Acute shortening osteotomy with internal fixation offers the advantage of a single-stage procedure that provides for decreasing the soft tissue loss, provides a rigid platform to protect the delicate neurovascular repair, and alleviates unwanted tension at the repair sites. This review discusses the literature on the surgical treatment of severe upper extremity trauma with associated neurovascular injury over the past 75 years, and aims to evaluate the indications, surgical techniques, clinical and functional outcomes, and complications associated with acute shortening osteotomy with rigid internal fixation. Although this technique is not without risks, it is well-tolerated in the acute setting with a complication profile comparable to other techniques of fixation while remaining a single procedure.

Lower Extremity Limb Salvage: Lessons Learned From 14 Years at War

American survivability during the current conflicts in Iraq and Afghanistan continues to improve, though the rate of extremity injury remains quite high. The decision to proceed with amputation versus limb salvage remains controversial. Exposure to combat wound with severe high-energy lower extremity trauma during the previous 14 years at war has incited important advances in limb salvage technique and rehabilitation.

Autologous segmental tibia bone transfer in the treatment of distal tibia Gustilo-Anderson type-III open fracture: A case report

•

Specific treatment modalities still remain a challenge in tibia fractures with bone and soft tissue loss.

•

Several treatment methods may be required in tibia fractures due to the poor coating of soft tissue.

•

The traditional treatment in open crus fractures with bone and soft tissue loss may cause miscellaneous complications.

•

Bifocal compression-distraction osteogenesis with an external fixator may be a salvage procedure to avoid complications of traditional methods.

•

The osteosynthesis with autologous tibia bone transfer may be employed by saving the segment inside abdominal wall, if suitable conditions are provided.

Introduction

We present the results of a two-stage reconstruction performed with autologous segmental tibia bone transfer on a distal tibia Gustilo-Anderson type-IIIC open fracture in this paper. Our aim is to discuss the results of this surgery, potential failures and complications in our procedures, and ways to protect against osteolysis.

Presentation of case

A 20-year-old male who has undergone surgery in our clinic for a Gustilo-Anderson type-III open fracture of the left tibia using autologous tibia segmental bone transfer. The first operation consisted of removing the exposed bony fragment and placing it in the abdominal wall. Fifty days after the first operation, an intramedullary nailing operation was performed using the autologous bone fragment kept in the abdominal wall. Before the final procedure, we assessed the viability of the bone fragment using scintigraphy as well as the paprika sign was observed on the fragment during operation. Patient was seen in follow-up every three weeks to evaluate for successful osteosynthesis; however, osteolysis eventually established in the 7th month of follow-up.

Discussion

Specific treatment modalities with each having different advantages and disadvantages are a matter of debate in tibia fractures with bone and soft tissue loss. To our knowledge, there are no such cases reported in the literature of autologous tibia bone transfer for osteosynthesis with the fractured bone segment temporarily being stored inside the abdominal wall for nutritional supplementation.

Conclusion

The osteosynthesis with autologous tibia bone transfer may be employed by saving the segment inside abdominal wall, if suitable conditions are provided.
