Rehabilitation care outcome of lower limb fractures in a Nigerian teaching hospital-a retrospective study.
Fracture is a common cause of injuries to lower extremities. It is clinically assumed that younger and male patients have better outcome following acute care rehabilitation rehabilitation: see physical therapy. of lower limb fractures. This study was therefore carried out to investigate pattern and outcome of acute care rehabilitation of lower limb fractures.
All cases of unilateral lower limb fractures referred for physiotherapy at LAUTECH LAUTECH Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Nigeria between November, 2001 and October 2006 were reviewed.

Key words, lower limb fractures, rehabilitation outcome
An injury which commonly occurs in the lower limbs is fracture involving bones of the lower extremities (1). In the United Kingdom, lower limb fractures account for approximately one third of all fractures with overall incidences of 3.4 per 1000 person years in women and 2.9 per 1000 person years in men between 1990 and 2001 (2). Hospital based studies in Nigeria and overseas have identified lower limb as the most common location of fractures with tibia tibia: see leg. reported as the most commonly fractured bone in the lower extremities (3-5).
Majority of lower limb fractures occur as a result of road traffic accident involving vehicle, motorcycle, or pedestrians and fall (6, 7) Risk factors for lower limb fractures (medical or non medical) include road traffic accident, dementia, osteoporosis, smoking and medications among others (2, 6-7). Medical risk factors lower limb fractures vary across different age group. Kaye and Jick (2) reported that dementia was a major risk factor for sustaining fracture of femur among people aged 80 years above. The authors also submitted that smoking and osteoporosis were important predictors of fractures of pelvis and femur among the elderly (50-79 years).
Lower limb fractures are often managed by close reduction and splinting splinting /splint·ing/ (splin´ting)
1. application of a splint, or treatment by use of a splint.
2. in dentistry, the application of a fixed restoration to join two or more teeth into a single rigid unit. . However, surgical interventions are required in cases of femur and open tibia fractures (4, 6). Rehabilitation is an important component of holistic care of patients with lower limb fractures pre and post reduction (8). The seven milestones of functional recovery following hip fractures as described by Giuccione et al (9) include supine supine /su·pine/ (soo´pin) lying with the face upward, or on the dorsal surface.

2. to sit transfer, sit to supine transfer, sit to stand transfer, independent ambulation on leveled surface with walker, independent ambulation on leveled surface with crutches, independent ascent and descent of stairs with a railing and crutches and independent ascent and descent of stars with crutches only. Attaining independence in the first five keys was also identified as the goals of acute care rehabilitation following hip fractures. A number of personal characteristics and clinical factors have been studied for their association with functional outcomes in hip fractures. These include age (10-12), gender (10,12,13,), cognitive status (14), history of previous fractures (12,15), site and side of fractures (10-12,15) surgical fixation (12,15), physical therapy treatment (12,13,15,16) and length of hospital admission (13,16).

However, few studies explored pattern of lower limb fractures and there is a dearth of information on rehabilitation outcome of lower limb fractures particularly in developing countries. This study was designed to investigate the outcome of acute care rehabilitation of lower limb fracture. Factors predicting outcome of acute care rehabilitation following fractures of lower extremities were also identified.
Procedure for data collection: The authors reviewed all cases of unilateral lower limb fractures referred to physiotherapy department of Ladoke Akintola University of Technology The conception of Ladoke Akintola University of Technology began in 1987 when Governor Adetunji Olurin, the then Military Governor of Oyo State, responding to a letter from the Governing Council of the Polytechnic Ibadan set up a seven member interministerial committee under the Teaching Hospital, Osogbo between November 2001 and October, 2006. Cases of bilateral, multiple lower limb fractures and lower limb fractures complicated with head injury were excluded from the study. The following information was retrieved from the case files of patients who met the inclusion criteria

Acute care rehabilitation was defined as having attained the first five milestones of functional recovery as earlier described by Guiciones et al (9). Outcome of acute care rehabilitation was classified as: discharged from rehabilitation programme against physiotherapist's advice, discharged satisfactorily, discharged on supervision by close relatives and inconclusive training in the use of axillary crutchca or walking frame for non-weight bearing ambulation training. Moreover, a patient was said to have been discharged satisfactorily having learnt the usage of axillary crutches or walking frame without supervision whereas discharged unsatisfactorily if otherwise as stated earlier.

P-value was set at 0.05.
A total of 197 patients with radiological evidence of lower limb fractures were referred for acute care rehabilitation during the study period. They consisted of 138 males and 59 females aged between 7 and 92 years with mean age 38.7 [+ or -] 17.77 years. About a half of these patients (48.2%) were aged between 20 and 39 years as shown in Table 1. Majority of these patients (86.8%) were ambulant before sustaining fractures of the lower extremities, 16 (8.1%) were ambulant with aids while the pre fracture ambulation status of 10 patients could not be ascertained.
Majority of the patients (74.6%) under review were involved in road traffic accidents at the time they had lower limb fracture while 3 (1.5%) of them had pathological fracture. Other causes of fractures were as shown in Table 2. The most common site of lower limb fracture during the study period was the femur (51.3%). This was closely followed by fracture involving tibia and fibula fibula (fĭb`yələ): see leg. (28.9%). Lower limb fracture rarely occurred at the pelvis (1.5%) (Table 2). Lower limb factures were often reduced by Plaster of Paris (POP) (43.0%) and internal fixation internal fixation
The stabilization of fractured bony parts by direct fixation to one another with surgical wires, screws, pins, or plates. (32.5%). Other methods of fracture reduction were as shown in Table 3.
Majority of the patients (87.3%) under review underwent non-weight bearing ambulation training with axillary crutches while the rest were trained with walking frame. More than half of the patients under review (67.8%) completed ambulation training with either crutches or walking frame between one and three physiotherapy sessions, however, thirty patients completed their training in four or more treatment sessions. Complications recorded during ambulation training included poor exercise tolerance (7.5%), fainting attack (5.6%) and pain (0.5%)
Three quarters of patients (75.1%) under review were discharged satisfactorily with either axillary crutches or walking frame while 13 (6.6%) were discharged on close supervision by their carers or relatives. Other patients (18.3%) were either discharged against physiotherapist's advice or had inconclusive training with crutches or walking frame. Outcome of acute care rehabilitation of the patients under review was found to be associated with age (p=0.03) (Table 4) and means of ambulation training (p=0.03) (Table 5), but not gender (p=0.12) (Table 6), sites (p=0.32) and methods of reduction of fractures (p=0.31)
The outcome of this study revealed that more males (70 .1%) than females sustained lower limb fractures. This is in agreement with the findings of previous studies (3, 5, 7) in Nigeria and overseas. One may speculate that males' greater participation in outdoor activities could be a reason for male gender's predisposition predisposition /pre·dis·po·si·tion/ (-dis-po-zish´un) a latent susceptibility to disease that may be activated under certain conditions.
1. to fractures of lower extremities. About a half of patients under review were young adults (20 39 years) in agreement with the submission of Oluwadiya et al (3) that lower limb fractures are often sustained by active segment of Nigerian population. This therefore brings about concern about the need for development of preventive measures against lower limb fracture among these age groups as they constitute the workforce of Nigerian population. Moreover, considering the burden of care, lower limb fractures in young adults may not only have negative impact on societal participation but also on national economic growth.
About three quarters of incidences of lower limb fractures as revealed by the outcome of this study were due to road traffic accident. Previous studies (2-5) have also identified auto crash as the most frequent cause of fractures of lower extremities. This implies that incidence of lower limbs fracture in our society may be reduced road if preventive measures are strictly adhered to. Campaign on road collision free society as embarked upon by the Federal Road Safety Commission can now be regarded as an important preventive measure of curtailing incidence of lower limb fractures.
Majority of patients under review had fractures affecting femur (50.3%) and shaft of tibia and fibula (24.5%). These findings were at variance outcomes of previous studies (3-5) in Nigeria and overseas that reported the shaft tibia and fibular fibular /fib·u·lar/ (fib´u-lar) pertaining to the fibula or to the lateral aspect of the leg; peroneal.
pertaining to the fibula. as most common sites of lower limb fractures. The low incidence of fractures of tibia and fibula as revealed in this study could be attributed to the fact that large proportions of these patients were not hospitalized. About a half of patients under review were managed by close reduction and splinting (Plaster of Paris and traction). This confirmed earlier findings by Oluwadiya et al (3) and Odelowo (7) in which majority of patient were managed non-operatively. However, the proportion of patients managed by internal fixation in this study was higher than those of previous studies (3,6). This could be due to the fact that the considerable proportion of patients in our study sustained fractures of femur than those reported in previous studies (3,5).
Majority of patients (87. 3%) under review were trained to ambulate am·bu·late

This may be because majority of the patients were young adults who could easily comprehend and handle crutch crutch (kruch) a staff, ordinarily extending from the armpit to the ground, with a support for the hand and usually also for the arm or axilla; used to support the body in walking.
n. ambulation. More than half of the patients under review (67.8%) completed ambulation training within three physiotherapy treatment sessions while others completed their training after four or more treatment sessions. The duration of completion of ambulation training may be attributed to age distribution of the patients under review and method of reduction of fracture that predominated in the study. In other words, young adults with internal fixation or Plaster of Paris had shorter duration of training than the elderly or patients managed on traction. However, the outcome of ambulation training of patients under review was not associated with the methods of fracture reduction as expected. These findings may be as a result of limitation imposed by our research design being a retrospective study retrospective study,
a study in which a search is made for a relationship between one phenomenon or condition and another that occurred in the past (e.g. . We therefore recommend the need for carrying out prospective studies to investigate the association between outcome of acute care rehabilitation of fractures and method of reduction of fractures.
The association between means of ambulation training and outcome of ambulation training, invariably in·var·i·a·ble

in·vari·a·bil , the outcome of acute care rehabilitation as revealed in this study could also be due to age distribution pattern and fracture management procedures earlier explained. It is often clinically assumed that young and male patients may have better outcome of ambulation training. On the contrary, our findings revealed association between outcome of training and age but net gender. Similarly, it is clinically assumed that patients with internal fixation (ORIF ORIF Open reduction and internal fixation, see there ) and closed reduction by Plaster of Paris should be able to learn ambulation with crutches or frame faster than those on traction. However we found out that outcome of ambulation training was not associated with fracture management procedures.
This study revealed that more males than females sustained lower limb fractures across all age groups. Fractures of lower extremities affect active segment of the patients under review. Moreover road traffic accident is a major cause of lower limb fractures with high proportion of fracture of femur. Preventive measures aimed at reducing road collision could play a significant role in curtailing incidence of lower limb fractures in our society. Age is an important determinant of outcome of ambulation training following fractures of lower extremities.
