Comparison and analysis of reoperations in two different treatment protocols for trochanteric hip fractures – postoperative technical complications with dynamic hip screw, intramedullary nail and Medoff sliding plate

Table 1 Treatment protocols for pertrochanteric and subtrochanteric fractures in the two treatment groups

Fracture type		Fixation method
Fracture type		Treatment protocol: MSP/DHS^a	Treatment protocol: IMN/DHS^b
Pertrochanteric
	Stable - 2 fragments^c	DHS
	Unstable - 3 or more fragments^c	MSP biaxial
	Unstable - no lateral and/or no posterior support^c	MSP uniaxial (locked)
	Stable^d		DHS
	Intertrochanteric comminution and/or subtrochanteric extension^d		IMN
Subtrochanteric		MSP uniaxial (locked)	IMN
	Fracture extension below >2 of	IMN or
	MSP plate screws^e	long DHS

^aMedoff sliding plate (MSP) / dynamic hip screw (DHS)
^bIntramedullary nail (IMN) / dynamic hip screw (DHS)
^cChoice of treatment based on Jensen Michaelsen and Seinsheimer classifications including analysis of lateral and posterior support
^dChoice of treatment based on intertrochanteric fracture comminution or subtrochanteric fracture extension
^eApproximately 10 cm below the lesser trochanter
