Objective: To evaluate the effect of previous cerebrovascular accident on outcome after hip fracture., Study Design: Prospective, consecutive., Patients: From July 1987 to March 1997, 862 community-dwelling patients sixty-five years of age or older who had sustained an operatively treated femoral neck or intertrochanteric fracture were prospectively followed., Intervention: All patients had operative fracture treatment., Main Outcome Measurements: Postoperative complications, in-hospital mortality, hospital length of stay, hospital discharge status, one-year mortality and place of residence, and return to preinjury ambulatory level, basic and instrumental activities of daily living status., Results: Sixty-three patients (7.3 percent) had a history of cerebrovascular accident; the fracture was on the hemiplegic side in forty-six (86.8 percent) of the fifty-three patients with hemiplegia. Patients who had a history of cerebrovascular accident were more likely to be male and have an American Society of Anesthesiologists (ASA) rating of III or IV. They were also more likely to have three or more comorbidities, be a home ambulator, and be dependent on basic and instrumental activities of daily living before hip fracture. Hospital length of stay was significantly higher for patients who had a history of cerebrovascular accident. There were no differences in the incidence of hospital mortality or one-year mortality between patients who did and did not have a history of cerebrovascular accident before hip fracture. In addition, at one-year follow-up, when controlling for prefracture level of function, there were no differences in the rate of functional recovery between the two groups of patients., Conclusions: The functional recovery of elderly hip fracture patients who had a prior cerebrovascular accident was similar to that of patients who had no history of a prior cerebrovascular accident.

Recent studies have suggested that patients with a history of diabetes undergoing hip fracture stabilization have higher rates of morbidity and mortality as well as poorer functional results than control groups of non-diabetics. This study was performed to evaluate the effect of diabetes on patient outcome after hip fracture. Between July 1987 and December 1996, 849 community dwelling elderly who sustained an operatively treated hip fracture were prospectively followed to determine the effect of diabetes on patient outcome. The predictor variable was the presence or absence of diabetes mellitus. Ninety-three patients (11%) had a history of diabetes. Diabetic patients were more dependent in activities of daily living and ambulation prior to hip fracture. The presence of diabetes mellitus also increased the likelihood of a patient dying during hospitalization, but had no effect on recovery of ambulatory ability or activities of daily living. Although diabetic patients have increased in-hospital mortality when compared to non-diabetic patients, patients with diabetes are just as likely to recover pre-fracture functional status as non-diabetic patients.

Seven hundred forty-nine community-dwelling, previously ambulatory, elderly patients who sustained a femoral neck or intertrochanteric fracture underwent prospective follow-up to determine whether anesthetic technique (spinal or general) had an effect on inpatient morbidity and mortality, or 1-year mortality. One hundred seven patients were excluded from the study as the anesthetic technique was "predetermined" based on a underlying medical condition. Of the remaining 642 patients, 362 (56.4%) received general and 280 (43.6%) received spinal anesthesia. Twenty (3.1%) patients died during hospitalization; 73 (11.4%) patients developed one or more postoperative medical complications. The 1-year mortality rate was 12.1%. There was no difference in inpatient morbidity and mortality, or 1-year mortality rates between patients receiving general or spinal anesthesia.

A study was performed to assess the impact of intensive inpatient rehabilitation on the outcome after a fracture of the femoral neck or an intertrochanteric fracture. Before 1990, our hospital did not have an inpatient rehabilitation program. On January 1, 1990, a diagnosis-related-group-exempt (DRG-exempt) acute rehabilitation program was initiated. Patients were discharged to this program after evaluation by a staff physiatrist. Before 1990, twenty-seven (9.0 per cent) of 301 patients were discharged to an outside rehabilitation facility. After January 1990, the percentage of patients who were discharged to the DRG-exempt program increased yearly, from nineteen (17 per cent) of 113 patients in 1990 to forty-one (64 per cent) of sixty-four patients in 1993; this difference was significant (p < 0.01). Before 1990, the average duration of the stay in the hospital was 21.9 days. After January 1990, the average duration for the patients who did not enter the rehabilitation program was 20.0 days whereas the average duration for those who did was 31.4 days (16.1 days for acute care and 15.6 days for the rehabilitation program). There were no differences in the hospital discharge status or in the walking ability, place of residence, need for home assistance, or independence in basic and instrumental activities of daily living at the six and twelve-month follow-up examinations between patients who had been managed before initiation of the rehabilitation program and those managed after it or between patients who had been discharged to this program after its initiation and those who had not. These results raise serious questions regarding the global cost-effectiveness of these programs for patients who have had a fracture of the femoral neck or an intertrochanteric fracture.

The effect of anesthetic technique on ambulation and functional recovery after hip fracture was studied in a series of 631 community dwelling, elderly patients. Functional recovery at followup was determined by an 11-item functional rating scale. In univariate analysis, recovery of ambulatory ability and percent functional recovery were significantly higher at 6 months for patients who had general anesthesia. When controlling for potential confounding variables, however, no differences were observed in recovery of ambulatory ability or percent functional recovery between the two groups at 3, 6, or 12 months after hip fracture.

Three hundred thirty-eight community dwelling, ambulatory, elderly patients who sustained a hip fracture were observed prospectively to determine which patient and fracture characteristics at hospital admission predicted functional recovery at 3, 6, and 12 months. Multiple logistic regression was performed to estimate the simultaneous contributions of the predictor variables to failure of functional recovery. Before sustaining a fracture, 16% of patients were dependent on basic activities of daily living and 46% were dependent on instrumental activities of daily living. By 1 year after fracture, 73% of the patients had recovered to their basic activities of daily living status before fracture whereas only 48% had recovered to their instrumental activities of daily living status before fracture. Patients who were age 85 years or older, who lived alone before sustaining a fracture, and who had one or more comorbidities were at increased risk of delay or failure in recovering basic activities of daily living. Only instrumental activities of daily living independence before fracture predicted failure to recover instrumental activities of daily living function by 3 and 6 months after fracture. At 1 year, patient age 85 years or older was the only predictor of failure to recover instrumental activities of daily living function that existed before fracture. Based on characteristics at admission, a group of patients at high risk for failure to recover basic activities of daily living function within 1 year of sustaining a hip fracture can be identified.

A prospective analysis was performed on 832 patients to determine the circumstances surrounding falls leading to hip fracture within a homogeneous, elderly urban population. Special emphasis was placed on the season of year, time of day, location of fall, and other circumstances in which the fracture occurred. All patients were community dwelling, cognitively intact, previously ambulatory elderly who sustained a femoral neck or intertrochanteric fracture. Most fractures occurred at home, particularly in patients who were older, less healthy, and poorer ambulators. More than 75% of fractures resulted from a fall while the patient was standing or walking. Most falls occurred during daylight hours with a peak seen in the afternoon. No seasonal variation in the incidence of hip fractures was observed.

Objective: To determine whether allogeneic red blood cell transfusion is a predictor for developing an in-hospital postoperative urinary tract, respiratory, or wound infection., Study Design: Prospective, consecutive., Methods: Six hundred eighty-seven community-dwelling, ambulatory, geriatric hip fracture patients were prospectively followed; all patients had operative fracture treatment and received perioperative antibiotics., Results: Sixty-eight patients had a culture-positive infection before operative treatment. One hundred thirty-four of the remaining 619 patients (21.6%) developed a postoperative infection, primarily a urinary tract infection. The infection rate was 26.8% in transfused patients compared with 14.9% in nontransfused patients (p = 0.001). When stratifying by the type of infection, only the risk of urinary tract infection was statistically significant (p = 0.001). After controlling for the effect of patient age, sex, number of preinjury medical comorbidities, American Society of Anesthesiologists (ASA) rating of operative risk, fracture type, surgical delay, type of surgery, type of anesthesia, operative time, and blood loss, the relationship between allogeneic red blood cell transfusion and postoperative urinal tract infection remained statistically significant., Conclusions: Geriatric hip fracture patients who receive allogeneic red blood cell transfusions are at higher risk for developing a postoperative urinary tract infection than are those patients who are not transfused.

Objective: To present a consecutive series of older patients with pubic rami fractures and evaluate their long term functional outcome., Study Design: Retrospective., Methods: Sixty-three consecutive community-dwelling, ambulatory patients who sustained a public rami fracture and were treated at one hospital were reviewed. Fifty-two of sixty-three patients (83%) had radiographic evidence of pubic rami fracture at initial presentation; in the remaining eleven patients, the diagnosis of pubic rami fracture was made after additional imaging studies. Sixty patients (95%) required hospitalization for pain control and progressive mobilization., Results: The hospital length of stay for the sixty admitted patients averaged fourteen days; patients who had three or more associated medical comorbidities or required use of a cane or walker for ambulation prior to fracture were more likely to have been hospitalized greater than two weeks. Thirty-eight patients were available for one year minimum follow-up; thirty-five of thirty-eight patients (92%) were living at home, 84% had no or mild complaints of hip/groin pain, 92% had returned to their prefracture ambulatory status, and 95% had returned to their performance function in activities of daily living., Conclusions: 1) Elderly patients with pubic rami fractures utilize substantial healthcare resources based upon length of stay and need for home care services; and 2) those patients who survive have a good prognosis with regard to long term pain relief and functional outcome.

A prospective analysis was performed involving 680 geriatric patients with hip fractures to determine whether the demographic profile of patients with femoral neck fractures was similar to that of patients with intertrochanteric fractures. All patients were community dwelling, cognitively intact, previously ambulatory elderly with femoral neck or intertrochanteric fracture. Three hundred fifty-eight patients (52.6%) sustained a femoral neck fracture; 322 (47.4%), an intertrochanteric fracture. Patients with an intertrochanteric fracture were significantly older, more likely to be limited to home ambulation, and were more dependent regarding basic and instrumental activities of daily living. After stratification by gender and adjustment for age, these differences remained significant in women only. There were no differences in age, prefracture ambulatory ability, or dependence in activities of daily living in men with either type of fracture.

Three hundred thirty-six community-dwelling, previously ambulatory, geriatric patients with hip fracture were observed prospectively to determine ambulatory ability at a minimum followup of 1 year. One hundred thirty-seven (41%) patients maintained their prefracture ambulatory ability at a minimum followup of 1 year; 134 (40%) patients remained ambulatory but became more dependent on assistive devices; 39 (12%) previous community ambulators became household ambulators, and 26 (8%) patients became nonfunctional ambulators. Analysis was performed to determine which pre- and postinjury factors were predictive of failure to recover ambulatory capacity 1 year after fracture. Potential predictor variables analyzed included age, gender, number of comorbid conditions, prefracture ambulatory ability, prefracture living situation, fracture type, American Society of Anesthesiologists rating of operative risk, type of surgery, and number of postoperative complications. Multiple logistic regression analysis identified significant contributions of age, prefracture ambulatory ability, American Society of Anesthesiologists rating of operative risk, and fracture type to ambulatory recovery.

A prospective study was performed comparing modified Knowles pins to cannulated cancellous screws for the treatment of nondisplaced and impacted femoral neck fractures. Forty-five impacted or nondisplaced fractures were identified: twenty-five were stabilized with modified Knowles pins and twenty with cannulated cancellous screws. Patient follow-up averaged twenty-four months (range 12 to 46 months) or until reoperation. Six patients (13%) required reoperation; these failures were evenly divided between the two groups. The remainder of patients (twenty-two patients (88%) in the Knowles pin group and seventeen patients (85%) in the cannulated screw group) were comparable with regard to functional outcome.
