Mobilisation strategies after hip fracture surgery in adults.

backgroundPost-operative care programmes after hip fracture surgery include strategies for mobilisation, such as early weight bearing, gait retraining and other physical therapy interventions.

objectivesTo evaluate the effects of different mobilisation strategies and programmes after hip fracture surgery. SEARCH STRATEGY: The Cochrane Musculoskeletal Injuries Group trials register, Medline, and reference lists of relevant articles were searched. Date of the most recent search: August 1999. SELECTION CRITERIA: All randomised or quasi-randomised trials comparing different mobilisation strategies/programmes after hip fracture surgery. DATA COLLECTION AND ANALYSIS: All reviewers independently assessed trial quality, using a ten item scale, and extracted data. Wherever appropriate and possible, the data are presented graphically. MAIN

resultsEach of the four included trials evaluated a different intervention. All had poor and / or poorly reported trial methodology. One trial of 100 patients compared twice daily with once daily physiotherapy. Only limited outcome data were available for checking the claims in the trial report that there was no demonstrable difference in recovery of the two patient groups at nine weeks follow-up. A treadmill gait retraining programme was compared with a conventional gait retraining programme in one trial of 40 patients. More patients in the treadmill group had recovered their pre-fracture level of mobility by the time of hospital discharge, which tended to happen earlier than for the control group. Neither of these differences were statistically significant. One trial of 24 patients compared neuromuscular stimulation of the quadriceps muscle with placebo stimulation. No data were available to test the claims that neuromuscular stimulation improved the recovery of mobility, assessed up to 13 weeks. One trial involving 273 patients with a displaced intracapsular fracture treated by internal fixation compared weight bearing at two weeks after surgery with delayed weight bearing at 12 weeks after surgery. From the limited data available, there were no statistically significant differences between the two methods of treatment for the outcomes of non-union, mortality and overall unfavourable outcome at one year (42/141 versus 50/132; relative risk = 0.79, 95%confidence interval = 0.56 to 1.10). REVIEWER'S

conclusionsThere is insufficient evidence from randomised trials to determine the effects of more frequent physiotherapy, treadmill gait retraining, or neuromuscular stimulation after hip fracture surgery. There is also insufficient evidence to determine the effects of early weight bearing after the internal fixation of an intracapsular proximal femoral fracture.
