There are many possible causes of hip pain. Finally, the validity of the DXA method for assessing change in soft tissue should be considered (30). These studies support the use of DXA for measuring small change in regional muscle mass over time. The surgery can correct the hip problem, but the muscles will remain weak and will only be strengthened through regular exercise. In contrast, loss of strength, measured by loss of grip strength (13)(14) or ankle dorsiflexion strength, was associated with a greater decline in mobility function and poorer recovery of function after the fracture, even when adjustments were made for potential confounders, including hip pain and morbidity, at the time of the fracture. Participants were categorized by tertile of nonfractured leg muscle mass change from baseline to month 12 (cutoff points <−3.3%, −3.3% to +5.5%, >+5.5%); by tertile of arm muscle mass change (cutoff points <−11.6%, −11.6% to 0, >0); by tertile of change in grip strength (cutoff points <−9.2%, −9.2% to +8.3%, >8.3%); and by tertile of change in ankle dorsiflexion strength of the nonfractured leg (cutoff points <0, 0 to +23.0%, >+23.0%). The importance of strength may have clinical implications for rehabilitation after hip fracture. Data were analyzed using SAS software (SAS Institute, Inc., Cary, NC). Hip flexor strain can occur when the hip flexor muscles are pulled, strained, torn or injured. Percentage of women who reported themselves as independent (black rectangles), needing any assistance (gray rectangles), or unable (white rectangles) to perform a mobility item before a hip fracture (Pre) and 12 months after the fracture (Post). In this analysis, the recovery score was also associated with chronic disease (those with more chronic illnesses were less likely to recover; p = .04) and with self-reported hip pain (women with hip pain had a poorer mobility recovery; p = .03). However, an underestimation of muscle mass loss may have been caused by several factors. It is thought that tightness in your hip flexor muscles in the front of your hip may lead to weakness in your gluteus medius muscles in the back and side of your hip. In fact, clinical trial data from growth hormone trials show increases in muscle mass but no improvement in functional ability (24). The correspondence between hip fracture patient and proxy has been demonstrated to be good for information on functional status, especially for lower extremity activities (15)(16). Jette AM, Harris BA, Cleary PD, Campion EW. These items have been used in elderly hip fracture patients and have been shown to be sensitive to change (3)(4)(17). For each mobility item, the percentage of women who were able to perform the item independently decreased after the fracture, and the percentage of women who were unable to perform the item increased after the fracture. Thirteen (14.4%) women were fully independent on all five mobility items before the fracture, whereas only two (2.2%) women were fully independent 12 months after the fracture. I am 48 and had a full hip replacement on Dec 27,2017 as an outpatient procedure. Body composition was measured using dual-energy x-ray absorptiometry (DXA) (models QDR-1000W and QDR-1500, Hologic, Inc., Waltham, MA). Darrell McIndoe and Arthur Serpick. Cartilage is a tissue that helps joints move. Your leg muscles are probably weak because you haven't used them much due to your hip problems. One thing is sure. Second, the women who completed the study and were included in our statistical analyses were relatively younger and healthier. During hip replacement surgery, the nerves in the leg, including the sciatic nerve, can sometimes be stretched or damaged. In conclusion, the results of the study suggest that loss of muscle strength after a hip fracture might lead to poorer mobility recovery 12 months after the fracture. Of the 407 identified cases, 205 patients participated in a baseline assessment of body composition; out of these, 90 patients with complete data were included in the present analyses. Although a relationship between change in muscle strength and change in mobility function was observed, the effect of a relatively small loss of muscle mass on functional decline might not have been detected. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. The muscle mass of the arms was calculated similarly. It is normal for muscles to feel sore or shaky when starting a new exercise 2. Conclusions. The change in arm muscle mass and ankle dorsiflexion strength were statistically significant ( p < .01). Weak leg muscles can make it difficult to walk or stand. Of the patients with intertrochanteric fractures, 95.9% had an internal fixation, and of the patients with a femoral neck fracture, 93.9% had an arthroplasty. These muscles are weak after a total knee replacement because of the direct trauma from the surgical incision, but also because swelling in the joint signals muscle inhibition, or shutdown, as a … In contrast to the results for muscle mass change, the decline in mobility function was associated with the change in muscle strength. Thus, instead of using peak muscle mass loss, we investigated the net change over 12 months. Future intervention studies should include strength measurements of different muscle groups to confirm our findings and to contribute to the development of optimal rehabilitation programs after a hip fracture. Values ranged from 0 to 5. Two prospective studies have investigated change in body composition after a hip fracture (10)(11) and observed a mean 5%–6% loss of total body lean mass and a 4%–11% gain in fat mass at 1 year postfracture. Overall Mobility Recovery Score 12 Months After Hip Fracture in Elderly Women by Tertile of Muscle Mass Change and by Tertile of Muscle Strength Change from Baseline to 12 Months (mean ± SE). At baseline, the mean difference in total leg mass between the fractured leg and the nonfractured leg was 1.3 kg (SD = 0.1 kg), suggesting that the leg and hip regions were swollen as a result of the fracture and the surgery. Background. All measurements were repeated at 12 months. Clench your butt at the top of the movement, pause, and lower back down. During this recovery phase, residual pain caused by the surgical procedure itself can cause a mild limp. Elderly women have a poorer functional recovery after a hip fracture (1)(2)(4)(5)(6) and are expected to have a greater loss of muscle mass and muscle strength. © 2019 www.azcentral.com. Grip strength and ankle dorsiflexion strength were used as indicators of muscle strength and were measured at baseline and at 12-month follow-up. The authors acknowledge the cooperation of medical and administrative personnel and the departments of orthopedic surgery at Union Memorial Hospital and Saint Joseph's Hospital; the commitment to measuring body composition by Bernadette Jenkins, Michele Gladfelter, and Sue Bright; assistance with patient recruitment from Penelope Smith; and the administrative oversight and expert consultation of Drs. The results of these earlier studies and this study suggest that change in strength may have a greater effect on physical function than change in muscle mass. At 2 to 10 days after hospital admission, the women's grip strength, ankle dorsiflexion strength, and regional muscle mass (by dual-energy x-ray absorptiometry) were measured, and the prefracture level of independence for five mobility function items was assessed. Pain, unlike soreness, is an indicator that you may be overdoing it with your exercises. Karlsson M, Nilsson JAÅ, Sernbo I, Redlund-Johnell I, Johnell O, Obrant KJ. Hold this contraction for two to three seconds and repeat 10 times. For each item, ability was rated on a 3-point scale: 0 = complete independence; 1 = needing some assistance (human or equipment); and 2 = complete inability to perform the activity. You sit in it and abduct your hips to move your thighs away from each other. Mean weight change at the 12-month follow-up was −2.9% (SD = 8.0%, p < .01). Two patients were still receiving physical therapy at 12 months. However, gently stretching and exercising the hips can often help relieve this pain. In rare cases, a malpositioned hip prosthesis implant can cause a limp after hip replacement surgery. Therefore, knowledge about potential determinants of functional recovery is important. Data on grip strength and ankle dorsiflexion were available for 71 and 69 women, respectively. No association was observed between loss of muscle mass and mobility recovery. Overall mobility recovery was calculated as the sum of the individual recovery scores of the five mobility items. The overall mobility score was calculated for each tertile of muscle mass change and muscle strength change (Table 4 ). In contrast, women who lost muscle strength during the 12 months after the fracture (tertile I) tended to have a poorer mobility recovery than those who gained muscle strength (tertile III). This study determines the change in muscle strength and muscle mass after a hip fracture, and the associations between these changes and mobility recovery. Hence, the total study cohort was divided into tertiles based on muscle mass change and muscle strength change. Magaziner J, Simonsick EM, Kashner TM, Hebel JR, Kenzora JE. The study was conducted with 90 women aged 65 years and older who had experienced a new fracture of the proximal femur. Stand in front of a table, chair, counter or other sturdy support and lift your affected leg off the ground and away from the center of your body. Fiatarone MA, O'Neill EF, Doyle Ryan N, et al. The excess of fluid and blood likely to cause the swelling is measured as lean soft tissue mass by DXA and would cause an overestimation of muscle mass in the affected leg at baseline, which would lead to an overestimation of muscle loss at follow-up when the swelling decreased. Although you’ll likely be functioning well 4 to 6 months after your surgery, weakness in the muscles surrounding your hip may persist for up to 2 years. The overall change in skeletal muscle mass was +1.1% (SD = 11.8%) for the nonaffected leg and −4.7% (SD = 13.7%) for the arms. Adjusted for age, body fatness, chronic illness, cognitive status, days hospitalized, and hip pain at 2 months. When the follow-up score was greater, recovery was coded 0 for that item. Results are presented as mean ± SD or mean ± SE. Weight change was positively associated with change in muscle mass ( p = .0001); it explained 23% of the variance in leg muscle mass change and 18% of the variance in arm muscle mass change. A threshold value for muscular strength has been reported below in which strength is critical to physical performance of the lower extremities (28). “After hip replacement, retraining of the muscles of the thigh is … Search for other works by this author on: Feature selection algorithms enhance the accuracy of frailty indexes as measures of biological age, Associations of Age, Sex, Race/Ethnicity and Education with 13 Epigenetic Clocks in a Nationally Representative US Sample: The Health and Retirement Study, Multimorbidity patterns and memory trajectories in older adults: Evidence from the English Longitudinal Study of Ageing, The Journals of Gerontology, Series A (1995-present), About The Journals of Gerontology, Series A, About The Gerontological Society of America, Receive exclusive offers and updates from Oxford Academic, Copyright © 2021 The Gerontological Society of America. So these muscles, then, are weak in someone with osteoarthritis of the hip joint. Hip fracture in elderly persons has a serious impact on long-term physical function. Note: A higher mobility function score indicates greater dependency. The result is that your left buttock will not ever be as strong as it was, nor as firm as your right cheek.” The largest muscles in my body were important to me for several reasons. Moreover, several validation studies that used changes in total body water during dialysis to simulate changes in total body lean mass of only 2%–4% have shown good results (33)(34). This stretch is also used during warm-ups to get your muscles ready for other exercises. The maximum strength results (in kilograms) of the two grip strength trials (right arm with patients seated) were used. Among the subgroup of women (n = 74) who were also measured at a 6-month follow-up, there was no significant association between the short-term change (from baseline to 6-month follow-up) in muscle mass or muscle strength and the short-term change in mobility function ( p > .2). This can happen if the surgeon fails to adequately seat or angle the implant in the leg (femur) bone. When confirmed by other studies, these findings may have implications for rehabilitation strategies after a hip fracture. The present study examined whether mobility recovery after hip fracture was related to change in appendicular skeletal muscle mass or to change in muscle strength. Your leg should be lifted out and to the side of your body with your knee straight. Women with the greatest decline in muscle mass (tertile I) had a lower cognitive status score, the highest muscle mass at baseline, and lost the most weight compared with the other tertiles. However, in a small number of cases, a limp can persist following hip replacement surgery. Restricting the analyses to those women who were mobility independent or used an assistive device (walker or cane) before the fracture showed similar results. Most of the loss in lean mass appeared to occur in the first 2 to 4 months after the fracture. Several factors should be considered that may explain the lack of association between change in muscle mass and mobility recovery. Muscle weakness after hip replacement can cause you to limp. The top of your femur is shaped like a ball and covered with cartilage. It merges with the gluteal muscles to stabilize the leg. Cummings SR, Phillips SL, Wheat ME, et al. Of these 90, 48 women (53.3%) had fractured the femoral neck, and 42 women (46.7%) had fractured the intertrochanteric region. When your leg muscles don’t contract as they should, you may feel as though the muscles in your legs are weak. The decline in mobility function after a hip fracture was not different between tertiles of leg muscle mass change or arm muscle mass change. A number of factors may be preventing you from getting the best results after your surgery. Skelton DA, Young A, Greig CA, Malbut KE. Overall, 95.6% of the patients received physical therapy between discharge and the 12-month follow-up. Complete information on the arms, that is, with no part of the arm outside the DXA scanning field, was obtained for 77 women. The overall mobility score increased from 2.31 ± 1.86 prefracture to 4.08 ± 2.35 12 months after the fracture ( p = .0001). Because these findings may have implications for the rehabilitation of elderly hip fracture patients, future studies are needed to determine the independent role of loss of muscle strength and loss of muscle mass on functional recovery in elderly men and women. Lie on your back, knees bent, feet flat on the floor. In fact, sometimes, the pain you experience is even worse than what you were experiencing before undergoing the surgery. 1. Both groups improved in gait speed, muscle strength, one-legged stance and quality of life. During this period, 75.6% of the patients performed exercises on their own; less than 5% of these used weights or resistance. The results suggest that loss of muscle strength, but not loss of muscle mass, is an independent predictor of poorer mobility recovery 12 months after a hip fracture. Go to activities that will help with swelling. Strengthening exercises, such as leg raises, clamshells, monster walks and side shuffles, may help. Hip impingement occurs when the normally smooth motion of the ball joint in the socket is interrupted, or the smoothness of the motion is impaired. Hip replacement surgery is very effective at reducing or eliminating hip joint pain and improving hip joint function. A leg length difference can cause a limp if the discrepancy is severe enough. In the weeks and months following total hip replacement surgery, the muscles surrounding the hip joint tend to be weak and atrophied, which can cause weakness of the leg as well as a limp. What to Expect From Meniscus Surgery and Recovery. The joint is held together by ligaments and muscles. The overall change we observed in appendicular skeletal muscle mass after a hip fracture was modest. If DXA was not feasible at day 3, the information collected at approximately day 10 after admission was used as the baseline value. A little detective work may help you avoid problems or provide a way to fix them. This is sometimes referred to as dormant butt syndrome.
