ABSTRACT: The results of total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH) in elderly patients (80 years or older) has not been well defined. The purpose of this retrospective study was to evaluate the clinical course of and the results in noncemented THA for ONFH in elderly patients.Between 1998 and 2007, one hundred seven consecutive hips with ONFH in 103 patients were evaluated. The causes of ONFH were traumatic in 46 (43%) hips and nontraumatic in 61 (57%) hips. All hips were treated with noncemented THA. Average follow-up was 72 months (range, 60-144 months). The functional results improved to statistical significance after THA. However, no significant differences existed between 6 months, 1 year, and 5 years postoperatively. Nine (8.4%) postoperative complications occurred in these 107 hips, including 1 stem loosening, 1 liner wearing, 4 postoperative infections, 2 postoperative dislocations, and 1 pulmonary embolism. Fifteen (14.6%) deaths occurred during follow-up. The progression of ONFH in elderly patients was so rapid and the result of core decompression was so poor that a salvage procedure seemed to have no role in the treatment. Harris Hip Score, Short Form 36 physical function score, and Western Ontario and McMaster Universities Osteoarthritis Index scores significantly improved after noncemented THA. Ninety-two hips had a complete follow-up, and the survivorship of prosthesis was 95% (88/92) with minimal 5-year follow-up. Noncemented THA was effective in the treatment of ONFH in this group of patients.

ABSTRACT: This study was conducted to evaluate the results of treating hypertrophic nonunion of mid-shaft clavicle fracture with a limited contact dynamic compression plate (LC-DCP) without autologous cancellous bone graft.
From 1995 to 2008, 51 cases of hypertrophic nonunion of mid-shaft clavicle fracture were managed with open reduction and internal fixation by LC-DCP without bone graft involvement. Of these 51 cases, 30 had nonunion after failure of initial surgical treatment (Group 1), and 21 had nonunion after failure of conservative treatment (Group 2). Preoperative and postoperative case management were the same for both groups, with the average follow-up period being 20.4 months (range 18-36). Our study evaluated the radiographic results and functional outcomes of these cases according to the quick disability of arm, shoulder, and hand score.
All 51 cases resulted in uneventful unions. There was no statistically significant difference between the two groups regarding patient demography, cause of injury, preoperative and postoperative functional scores, length of operation, union time, and duration of hospitalization (p>0.05).
LC-DCP fixation is an effective method for treating hypertrophic nonunion of mid-shaft clavicle fracture. Local bone graft is sufficient to achieve necessary union, and autologous bone graft from other sites of the body appears unnecessary.

ABSTRACT: The effects of cerclage wiring in the open reduction and internal fixation of displaced associated anterior column and posterior hemi-transverse acetabular fractures were evaluated.
This is a retrospectively clinical study of such cases where the main surgical strategy was open reduction and internal fixation with cerclage wire and reconstruction plates. Data on 12 cases treated between 1992 and 2011 were collected. The mean follow-up period was 32 (12-132) months.
Reduction with a fracture gap of less than 2 mm without articular stepping and solid union was achieved in all 12 cases. Postoperative complication developed in one case of symptomatic arthritis. Excluding the case with symptomatic arthritis, the other cases had good to excellent final D'Aubigne and Postel functional results.
Cerclage wiring is very useful and effective in the reduction and fixation of displaced associated anterior column and posterior hemi-transverse acetabular fractures, and supplemental fixation with reconstruction plates and screws is necessary.

ABSTRACT: The aim of this study was to establish and evaluate the effectiveness of a care map for total knee replacement patients.
Bureau of National Health Insurance in Taiwan is about to launch a diagnosis-related group. This major reform has seriously affected the running of medical institutions, which are facing unprecedented management pressure.
A quasi-experimental control group design was carried out.
Eighty-three patients were recruited, with 39 experimental group patients received nursing care based on a care map, while 44 patients who were in control group received routine nursing care. An interdisciplinary team designed the care map, which included items required for patient care from outpatient to postdischarge.
(1) The mean age of patients was 72·73 (SD 8·42) years. Mean length of stay was 4·92 (SD 0·77) days for the experimental group and 7·09 (SD = 1·09) for the control group. Difference between groups was significant (t = -10·285, p < 0·001). The medical cost for the experimental group was less than that for the control group (t = -6·03, p < 0·001). (2) The self-care efficacy score before discharge for the experimental group was higher than that for the control group (t = 5·90, p < 0·001). (3) Significant improvements were observed in activities of daily living for both groups with the passage of time after discharge (F = 229·034, p < 0·001), and the experimental group was better than the control group (F = 40·895, p < 0·001). The instrumental activities of daily living abilities of both groups were also significant improvements with the passage of time after discharge (F = 46·568, p < 0·001), and the experimental group was better than the control group (F = 32·163, p < 0·001).
A care map for total knee replacement patient can shorten length of stay, save medical cost and improve patient's functional recovery.
Results of this study can be used as a basis for practical implementation of care map in total knee replacement patients.

ABSTRACT: Elastic (Esmarch) bandage exsanguination is widely used in lower limb surgery to provide a bloodless operating field. Nevertheless, it is still not known exactly how exsanguination through Esmarch bandage usage contributes to venous pressure physiology following TKA. We wished to determine whether exsanguination with Esmarch bandage affects the venous hemodynamics of the lower limb in the first few weeks following TKA, so a prospectively randomized study was set. We prospectively collected consecutive 38 male patients with unilateral advanced osteoarthritis of the knee. All of the subjects were randomly assigned to one of two TKA procedures: TKA with (Group A) or without (Group B) Esmarch bandage exsanguination. No pharmacologic thromboembolic prophylaxis was used in this study. The venous hemodynamics of each operated leg was assessed by strain-gage plethysmography, firstly before the operation, then postoperatively on days 2, 6, 14 and 28. The postoperative results revealed significant falls in venous outflow 2, 6 and 14 days following TKA in Group A; and 2 and 6 days following TKA in Group B. Twenty-eight days after TKA, venous outflow in both groups had returned to baseline level. Over the 28 days following the operation, Group A venous outflow tended to fall more significantly than in Group B. As with venous outflow, venous capacitance in both groups showed significant falls 2 and 6 days following TKA, with recovery to baseline levels 28 days postoperation. More significant falls in arterial filling index were recorded in Group A 6 days following TKA, returning to their baseline level 14 days postoperation. It appears that better leg venous hemodynamic changes are attained during the first month after TKA in Group B. We therefore question the need for exsanguination with Esmarch bandage before knee arthroplasty.

ABSTRACT: We evaluated the effect of revision with dynamic compression plate and cancellous bone graft for aseptic nonunion after intramedullary nailing of femoral shaft fracture. Fifty patients with aseptic nonunion of femoral shaft fracture after intramedullary nailing were reviewed and analyzed retrospectively between 1996 and 2007. There were 40 men and 10 women with an average age of 44 years (range, 19-76 years). Thirty-five were diaphyseal fractures, 8 were distal fractures, and 7 were proximal fractures. Twenty-eight fractures were defined as atrophic nonunion, 13 fractures were hypertrophic nonunion, and 9 fractures could not be defined clearly. All fractures were managed by retaining previous implants, open reduction and internal fixation with dynamic compression plate, and supplementation by cancellous bone graft. The average follow-up period was 76 months (range, 24-128 months). Functional evaluations were done by Harris Hip score and Hospital for Special Surgery knee score. All nonunions united on average at 24 weeks (range, 18-32 weeks). One superficial wound infection occurred. At follow-up, each patient was evaluated to have satisfactory function results, with near normal hip/knee functions without noticeable pain, and full return to preinjury activities/work without pain.Augmentative dynamic compression plate with cancellous bone graft is a reliable and effective treatment for revision of aseptic nonunion of femoral shaft fracture after intramedullary nailing.

ABSTRACT: The objective of this study was to understand the following: (1) the specific care needs of geriatric hip fracture patients; (2) the level of care difficulty during the transition period following discharge; and (3) the correlation amongst demographics, the physical function status of the elderly, and care needs. Purposive sampling was used, and a total of 71 hip fracture cases and their caregivers were selected. A survey was carried out to collect data just before discharge and one week following discharge. Statistical methods included descriptive statistics, correlation analysis, one-way ANOVA, and a paired t-test. Results were as follows: Most geriatric patients depended upon care from family members before discharge, with an average physical function status score of 6.99 (0 to 18) that improved significantly after one week to 10.27; paired t = -7.956 (p < .000). The mean age of primary caregivers was 51.72 years old (SD = 14.05). Most caregivers (47, or 66.2%) were female. The relationship between elderly participants and their primary caregiver was predominantly that of husband and wife (22 people; 31.0%). Participant care needs identified included return visit assistance, awareness of safety at all times, assistance with cleaning and maintaining living quarters, and so on. Caring tasks that were identified as more difficult for the primary caregivers includes providing stair climbing assistance, emotional problems management assistance, walking training assistance, rehabilitation assistance, and emergency disease management assistance. The care needs of the elderly in this study and level of execution difficulty for caregivers was found to be negatively related to the physical function status of the elderly. The study results suggest that providing patient-related home care knowledge to primary caregivers prior to discharge from the hospital and enhancement of the social support system are both needed.
