155 Tibial Malrotation Following Intramedullary Nailing: A Literature Review

Aim

The use of intramedullary nail fixation remains the operation of choice for managing unstable and displaced tibia diaphyseal fractures. The literature shows that although commonly performed, there is not a standard approach when performing intramedullary nailing of the tibia; it could be hypothesised that this lack of standardisation may be contributing to the noted complications. This systematic review will look into intramedullary nailing of the tibia in all its parts, from identification of patients through to the surgical procedure techniques and finally the intra- and post-operative complications.

Method

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Search terms included “tibial intramedullary nail” OR “tibial intramedullary rod” OR “tibial IM nail” OR “tibial interlock” AND “malrotation”, and “tibial intramedullary nailing” OR “tibial im nail” OR “tibial interlock” OR “tibial rod” AND “malrotation”.

Results

Eleven studies were considered in the final analysis, with a total number of 425 fractures (n=429, mean ± 95% CI=39 (21.2–56.8)). All included patients were treated with tibial intramedullary nail devices, and 110 showed some degree of malrotation postoperatively (n=110, mean ± 95% CI=10.1 (4.26–15.9)). Expressed as a percentage, a mean of 34.1% of patients had malrotation (mean ± 95% CI: 34.1 (15.8–52)).

Conclusions

This systematic review revealed there are gaps in the literature and in the management process of these patients and suggested that a systematic approach using ‘Get It Right First Time’ (GIRFT), intraoperative assessment, validated assessment tools, and imaging postoperatively should be used to improve outcomes.

Tibial Malrotation Following Intramedullary Nailing: A Literature Review

The use of intramedullary nail fixation remains the operation of choice for managing unstable and displaced tibia diaphyseal fractures. The literature shows that although commonly performed, there is not a standard approach when performing intramedullary nailing of the tibia; it could be hypothesised that this lack of standardisation may be contributing to the noted complications. This systematic review will look into intramedullary nailing of the tibia in all its parts, from identification of patients through to the surgical procedure techniques and finally the intra- and post-operative complications. 

A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Search terms included “tibial intramedullary nail” OR “tibial intramedullary rod” OR “tibial IM nail” OR “tibial interlock” AND “malrotation”, and “tibial intramedullary nailing” OR “tibial im nail” OR “tibial interlock” OR “tibial rod” AND “malrotation”. Two independent reviewers conducted searches in PubMed, OvidSP for Medline and Embase as well as Cochrane Library using the same search strategy. Searches were conducted on 20 January 2021. Any disagreements were resolved by discussion with a third independent reviewer.

This systematic review revealed there are gaps in the literature and in the management process of these patients, and suggested that a systematic approach using ‘Get It Right First Time’ (GIRFT), intraoperative assessment, validated assessment tools, and imaging postoperatively should be used to improve outcomes. Following the use of this framework, it is hoped that the incidence of malrotation post tibia intramedullary nailing will be reduced, however, it is acknowledged that more high evidence studies need to be carried out and further done to optimise the care of these patients.

The Role of Point of Care Ultrasound (PoCUS) in Orthopaedic Emergency Diagnostics

Ultrasound has been described as the "stethoscope" of the radiologist; its ability to aid in clinical diagnosis with both static and dynamic imaging has allowed fast and accurate diagnosis. However, traditionally unlike a stethoscope, a large and bulky ultrasound machine made it difficult to use portably in a hospital environment where patients can be scattered across a hospital. With the development of innovative ultrasound technology, Point of Care Ultrasound (PoCUS) can readily be carried by a clinician to make a quick and timely diagnosis. In this review article we look at the uses of PoCUS within orthopaedic emergencies. Diagnosis in orthopaedics often requires further imaging beyond history taking, clinical examination and plain radiographs. In these cases PoCUS can be useful for ruling out occult fractures, diagnosing joint effusions and tendon ruptures. By aiding a speedy diagnosis, we can reduce unnecessary immobilisation, reduce inpatient stays, introduce early mobilisation and reduce harm to patients. With PoCUS becoming increasingly cheaper and more portable we feel this really can become the stethoscope of an orthopaedic surgeon.
