Comparative efficacy of proximal femoral nail vs dynamic condylar screw in treating unstable intertrochanteric fractures

Table 1 The general characteristics of the included studies

Ref.	Study type	Center	Study period	Follow-up in mo	Number of patients		Average age in yr		Sex as male/female		Fracture type and n	Conclusion
					PFN	DCS	PFN	DCS	PFN	DCS
Şensöz et al[18], 2023	Retrospective cohort	Dr. Lutfi Kirdar Kartal City Hospital, Istanbul, Turky	Between 2013 and 2018	At least 2 yr	36	25	65.52	59.36	15/21	13/12	A2.3 61	DCS was superior to PFN in early fracture union time. However, it showed a higher nonunion rate. PFN showed shorter hospital stay time than DCS and is recommended to be applied in that fracture type
Jamil et al[14], 2022	RCT	Jawaharlal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, India	Between November 2019 to December 2021	NA	15	11	54.20	59.82	4/11	6/5	A2.2 16/A2.3 10	PFN showed better results than DCS regarding operative time, union rate, duration for fracture union, and rate of complications
Ghilzai et al[15], 2016	RCT	Liaquat National Hospital, Karachi, Pakistan	February 2012 to August 2013	NA	21	19	80.00	77.00	NA	NA	A2.2 21/A2.3 19	PFN is superior to DCS in the treatment of proximal femur fractures type 31A3
Sahin et al[19], 2014	Retrospective cohort	Izmir Tepecik Education and Research Hospital, Izmir, Türkiye	Between January 2007 and December 2010	At least 1 yr	42	37	51.75	57.50	17/25	18/19	A2.2 44/A2.3 35	PFN is superior to DCS in the treatment of unstable peritrochanteric fractures, owing to its effect in reducing operative blood loss, and biological fixation achievement
Elis et al[20], 2012	Retrospective cohort	Tel Aviv Sourasky Medical Center, Tel Aviv, Israel	Between January 2006 and July 2009	At least 1 yr	19	14	51.75	57.50	3/16	3/11	A2.2 19/A2.3 14	EPFN was as effective as DCS devices for the treatment of reverse oblique hip fractures
Sadowski et al[16], 2002	RCT	University Hospital of Geneva, Geneva, Switzerland	Between March 1998 and June 1999	At least 1 yr	20	19	88.00	77.00	7/13	4/14	A2.2 20/A2.3 19	The results support the use of PFN rather than DCS for the treatment of reverse oblique and transverse intertrochanteric fractures

DCS: Dynamic condylar screws; EPFN: Expandable proximal femoral nail; NA: Not available; PFN: Proximal femoral nail; RCT: Randomized controlled trial.
