The Epidemiology of Adult Distal Femoral Shaft Fractures in a Central London Major Trauma Centre Over Five Years

Abstract

Background:Distal femoral fractures account for 3-6% of adult femoral fractures and 0.4% of all fractures and are associated with significant morbidity and mortality rates. As countries develop inter-hospital trauma networks and adapt healthcare policy for an aging population there is growing importance for research within this field.Methods:Hospital coding and registry records at the central London Major Trauma Center identified 219 patients with distal femoral shaft fractures that occurred between December 2010 and January 2016. CT-Scans were reviewed resulting in exclusion of 73 inappropriately coded, 10 pediatric and 12 periprosthetic cases. Demographics, mechanism of injury, AO/OTA fracture classification and management were analyzed for the remaining 124 patients with 125 fractures. Mann Whitney U and Chi Squared tests were used during analyses.Results:The cases show bimodal distribution with younger patients being male (median age 65.6) compared to female (median age 71). Injury caused through high-energy mechanisms were more common in men (70.5%) whilst women sustained injuries mainly from low-energy mechanisms (82.7%) (p<0.0001). Majority of fractures were 33-A (52.0%) followed by 33-B (30.4%) and 33-C (17.6%). Ninety-two (73.6%) underwent operative management. The most common operation was locking plates (64.1%) followed by intramedullary nailing (19.6%).Interpretation:The epidemiology of a rare fracture pattern with variable degrees of complexity is described. A significant correlation between biological sex and mechanism of injury was identified. The fixation technique favored was multidirectional locking plates. Technical requirements for fixation and low prevalence of 33-C fractures warrant consideration of locating treatment at centers with high caseloads and experience.

Patterns, Management, and Outcome of Traumatic Femur Fracture: Exploring the Experience of the Only Level 1 Trauma Center in Qatar

“…Femur is the most fractured long bone in the body that often necessitates surgical fixation [ 2 ]. Femoral shaft fractures have bimodal distribution across different age groups with high velocity injuries, which are more common among adult males, while low energy injuries tend to be more common in children and elderly females [ 3 ]. The most frequently injured site of femur is the midshaft, particularly among adult population following road traffic collisions [ 4 ].…”

Infected Non-Union of the Distal Femur

“…Three to six percent of adult femoral fractures and 0.4% of all fractures are distal femoral fractures, with a bi-modal distribution usually consisting of younger patients with high-energy injuries and older patients with minor trauma fractures [1]. The reported levels of non-union in the lateral locking plate differ widely, with some early studies showing rates of less than 6% and up to 17%-21% in more recent studies [2][3][4].…”

Functional outcome of distal femoral fractures managed surgically using locking compression plate laterally and augmented with titanium elastic nail system medially

“…The incidence of these fractures is 0.5% of all fracture and 3% of all femoral fractures.The distribution of fractures is higher Functional outcome of distal femoral fractures managed surgically using locking compression plate laterally and augmented with titanium elastic nail system medially in woman of age more than 75 years and in adults ranging between 15-25 years. 2 Restoration of complete knee range of motion and function is highly challenging since these fractures are very close to the knee joint. 3 The management of distal femur fractures has both conservative as well surgical method for the treatment.…”
