The aim of this study was to determine medium term functional outcomes in military casualties undergoing limb salvage for severe open tibia fractures, and compare them to trans-tibial amputees. Cases of severe open diaphyseal tibia fractures sustained in combat between 2006 – 2010 were contacted and interviewed. These results were compared to a similar cohort of 18 military patients who sustained a unilateral trans-tibial amputation in the same period. Forty-nine patients with 57 severe open tibia fractures met the inclusion criteria, of which 30 patients (61%) were followed-up. Ten of the 30 patients required revision surgery, 3 of which involved conversion to a circular frame. Twenty-two of the 30 patients (73%) recovered sufficiently to complete a basic military fitness test. The median physical component score of SF-36 in the limb salvage group was 46 (IQR 35–54) which was similar to the trans-tibial amputation cohort (p=0.3057, Mann-Whitney). There was no significant difference in the proportion of patients in either the amputation or limb salvage group reporting pain (p=0.1157, Fisher's exact test) or with respect to SF-36 physical pain scores (p=0.5258, Mann-Whitney). This study demonstrates that medium term outcomes for military patients are similar following trans-tibial amputation or limb salvage following combat trauma.

The aim of this study was to characterise severe open tibial shaft fractures sustained by UK military personnel over 10-years of combat and to determine the infection rate and factors that influence it. The UK military Joint Theatre Trauma Registry was searched and X-rays, clinical notes and microbiological records were reviewed for all patients. One hundred GA III open tibia fractures in 89 patients were identified. Three fractures were not followed up for 12-months and were therefore excluded. Twenty-two (23%) of the remaining 97 tibial fractures were complicated by infection requiring surgical treatment, with S. aureus being the causative agent in 13/22 infected fractures (59%). Neither injury severity, mechanism, the use of an external fixator, the need for vascularised tissue transfer or smoking status were significantly associated with infection. Bone loss was significantly associated with subsequent infection (p<0.0001). Most infection in combat open tibia fractures is caused by familiar organisms i.e. S. aureus. The use of external fixators to temporarily stabilise fractures is not associated with an increased risk of subsequent infection. While the overall severity of a casualty's injuries was not associated with infection, the degree of bone loss from the fracture was.

The aim of this study was to establish medium term outcomes in military casualties following severe open tibia fractures.

Cases from a previously published series were contacted and assessed with the SF-36 outcome tool. Their results were then compared to a similar study of military trans-tibial amputees.

Of the original data set of 49 patients, 30 patients were followed up and completed an SF-36 (61%) with a median follow-up of 4 years (49 months, IQR 397–63). Ten of the 30 required revision surgery, 3 of which involved conversion from initial fixation to a circular frame. Twenty-two of the 30 patients recovered sufficiently to complete a military basic fitness test. The median physical component of SF-36 in the tibia fracture group was 46 (IQR 35–54) which was similar to the trans-tibial amputation cohort (p=0.3057, Mann-Whitney). Similarly there was no difference in mental component scores (p=0.1595, Mann-Whitney). There was no significant difference in the proportion of patients in the amputation or fracture group reporting pain (p= 0.1157, Fisher's exact test) or with respect to SF-36 physical pain scores (p=0.5258, Mann-Whitney).

We present the patient reported outcomes following combat open tibia fracture and show that they are similar to those achieved after trans-tibial amputation.

We present the British Military's experience of treating devastating lower limb injuries in personnel returning from Iraq and Afghanistan. We evaluate current surgical practice of attempting to maximise stump length through sequential debridement, rather that early amputation outside the zone of injury. Following an observation that the frequency of sequential amputation had appeared to increase during spring 2009, it was speculated that there may be factors which would predict which patients would require a more aggressive early amputation.

The Joint Theatre Trauma Registry was interrogated for all cases of amputation between Apr 06 and Sep 09. The following data were collected: demographics, mechanism of injury, requirement for massive transfusion, use of combat applied tourniquet, number of stump debridements and echelon of care performed at, all microbiology and final level of amputation. A regression analysis was performed to establish correlation between each data-set and final level of amputation. 95 cases were identified; 21 were either digits or upper limbs and excluded. Clinical notes of the remaining 74 cases were requested, of which 48 were available representing a total of 66 lower limb stumps.

No significant relationships were established between sequential amputation and any of the variables we examined. It was not possible to identify factors with predictive value with respect to which patients would benefit from a more aggressive early amputation approach. These results support current practice by demonstrating that attempts to balance maximal stump length with sufficient debridement to eradicate infected tissue, does not expose patients to unnecessary operative “hits”.
