Table 1

Breakdown of patient demographics, with respect to location of periosteum retrieval and time since initial injury for histological analysis and cellular work.

Sex & age (years)		Harvested from	Time since injury (weeks)	Previous surgeries	Surgery carried out
Histology	M, 23	Femur	57	2	IMN
	M, 35	Humerus	108	None	Bone graft with BMAC
	M, 47	Femur	19	None	RIA graft
	F, 74	Femur	49	2	IMN, bone graft
	F, 80	Femur	17	2	2^nd stage Masquelet
Cellular work	M, 17	Femur	65	2	IMN
	M, 44	Tibia	11	1	IMN
	F, 49	Femur	155	1	IMN
	M, 49	Femur	12	1	Plate fixation
