Total hip arthroplasty for treatment of elderly patients with comminuted intertrochanteric fracture accompanied by femoral head necrosis

Objective： To assess the curative effect and investigate the indications of total hip arthroplasty for treatment of comminuted intertrochanteric fractures.
Methods： Total hip arthroplasty was carried out in 9 cases of severe intertrochanteric fracture. The patients included two men and seven women. The average age of the patients was 68 years （48-75 years）. The period from fracture to operation was 5 days （2-10 days）. The mean follow- up period lasted for 11 months （3 months-2 years）. There was one patient with comminuted intertrochanteric fracture accompanied by femoral head necrosis and 2 patients with intertrochanteric fracture and stroke. Other 6 patients had severe osteoporosis. The Harris score before operation was 63 points （45-71 points）.
Results： At the last follow-up, the patients gained 86points （70-100 points） according to the Harris score. The effects of the 8 cases were good. The Harris score of all patients improved after treatment. Only two hemiplegia patients needed sticks to walk. The others could walk without hip pain. No radiographic evidence of acetabular wear and prosthesis dislocation or other major complications happened during the follow-up.
Conclusions： Prosthetic replacements can well treat unstable intertrochanteric fracture if operative indication is correctly selected. It is suitable for elderly patients and the operation should be performed by experienced surgeons.     

Preliminary effect of proximal femoral nail antirotation on emergency treatment of senile patients with intertrochanteric fracture

Objective： To retrospectively analyse the clinical outcome of emergency treatment of senile intertrochanteric fractures with proximal femoral nail antirotation （PFNA）.
Methods： From September 2008 to March 2009, 35 senile patients with intertrochanteric fracture, aged from 65 to 92 years with an average age of 76.5 years, were treated with PFNA within 24 hours after injury. There were 10 type Ⅰ fractures, 19 type Ⅱand 6 type Ⅲ according to upgraded Evans-Jensen classification system. All patients were complicated with osteoporosis, and 19 patients had preexisting internal medical diseases. According to the rating scale of disease severity by the American Society of Anesthesiologists （ASA）, there were 9 grade Ⅰ, 14 grade Ⅱ, 8 grade Ⅲ, and 4 grade Ⅳ.
Results： The duration for operation ranged from 45 to 73 minutes with an average of 57.6 minutes. The volume of blood loss during operation ranged from 50 to 120 ml with an average of 77.5 ml. Patients could ambulate 2-4 days after operation （mean 3.5 days）. Hospital stay was 4-7 days （mean 5.3 days）. Full weight bearing time was 10-14 weeks （mean 12.8 weeks）. During hospitalization period, there was no regional or deep infection, hypostatic pneumonia, urinary tract infection and bedsore except for 2 cases of urine retention. All cases were followed up with an average period of 12.3 months, and bone healing achieved within 15-18 weeks （mean 16.6 weeks）. No complications such as delayed union, coxa vara or coxa valga, screw breakage or backout occurred and only 2 cases had troehanter bursitis because of thin body and overlong end of the antirotated nail. According to the Harris grading scale, the results were defined as excellent in 21 cases, good in 9 cases and fair in 5 cases, with the excellent and good rates of 85.7%.
Conclusion： The emergency treatment of senile intertrochanteric fracture with proximal femoral nail antirotation has the advantages of minimal invasion, easy manipulation, less blood loss, shorter length of stay, less complications, and the preliminary clinical effect is satisfactory.     

Effect of dynamic hip screw on the treatment of femoral neck fracture in the elderly

[Abstract] Objective： To discuss the indications, surgical procedures, and curative effect of dynamic hip screw （DHS） in the treatment of femoral neck fracture in the elderly. Methods： A retrospective study was conducted to analyse the clinical data of 42 elderly patients who had been treated for femoral neck fracture with DHS in our department between June 2009 and November 2011. There were 21 males and 21 females with a mean age of 68.5 years （range 60-75 years）. According to the Garden Classification, there were 19 cases of type II, 21 cases of type III and 2 cases of type IV fractures. By the Singh In- dex Classification, there were 3 cases of level 2, 19 cases of level 3 and 20 cases of level 4 fractures. The Harris cri- terion, complications and function recovery after operation were analysed. Results： The average hospitalization time in 42 patients was 11.2 days （range 7-21 days）. All patients were followed up for 12-26 months （mean 18 months）. No lung infection, deep venous thrombosis or other complications occurred. Partial backing-out of the screws was found in 2 cases. The internal fixation device was with- drawn after fracture healing. Internal fixation cutting was found in 1 case, and he had a good recovery after total hip arthroplasty. The time for fracture healing ranged from 3-6 months （average 4.5 months）. According to Harris criteri- on, 15 cases were rated as excellent, 24 good, 2 fair and 1 poor. The Harris scale was significantly improved from 30.52＋2.71 preoperatively to 86.61＋2.53 at 6 months post- operatively （P〈0.05）. Conclusion： DHS, being minimal invasive, al- lowing early activity and weight-bearing, is advisable for treatment of elderly patients with femoral neck fracture. In addition, it can avoid complications seen in artificial joint replacement. It is especially suitable for patients with mild osteoporosis.     

应用羟基磷灰石喷涂解剖型股骨假体的中期随访结果

Objective To observe the clinical and radiographic outcomes following the THA using a hydroxyapatite-eoated anatomic stem. Methods From 2001 to 2003, 90 total hip arthroplasty were per-formed in 75 patients using a hydroxyapatite-coated anatomic stem. There are 49 males and 26 females, with the mean age of 58.4 years, range from 42 to 68 years. The mean follow-up period was 7.2 years (5 to 8 years). All patients were evaluated clinically using Harris hip score; preoperative and follow-up radiographs were made. Results Forty-eight patients with 56 hips were involved in this study. There were 29 males and 19 females were included. No patients had underwent revision arthroplasty or aseptic loosening. Accord-ing to the Harris hip score, the average hip score increased from 28.23=6.3 before operation to 93.23±4.8 one year after operation and to 91.6±4.5 at the final review. There was significant difference between the Harris scores at final review and preoperative ones, but no difference one year after operation. All patients had ex-cellent or good results. Three cases were found to be associated with thigh pain. All prostheses were well os-seointegrated. Limited proximal femoral osteolysis occurred in two cases, three cases had radiographic evi-dence of osteosclerosis on the tip of the stem, and six cases were found to represent discontinuous radiolu-cent lines surrounding the stem on the radiographs. No stem subsidence and varus/valgus happened. Con-clusion Hydroxyapatite-coated anatomic stem provided favorable clinical and radiographic results after an intermediate duration of follow-up. The prosthesis had achieved reliable bone ingrowths. The long-term re-sults is needed to be confirmed in future.

Clinical observation of particulate cancellous bone impaction grafting in combination with total hip arthroplasty for acetabular reconstruction

Objective： To investigate the effect of particulate cancellous bone impaction grafting in combination with total hip arthroplasty （THA） for acetabular reconstruction in patients with posttraumatic arthritis and bone loss after acetabular fractures.
Methods： Totally 15 consecutive cases with unilateral acetabular fracture were treated with bone impaction grafting in combination with THA in our department. There were 10 males and 5 females with mean age of 48.2 years （ranging from 36 to 73 years）. Eight cases had the fracture at left hips, 7 at right hips. The average age at injury was 28 years （ranging from 18 to 68 years）. The mean follow-up period was 4.3 years （ranging from 2 to 7 years）. Results： Compared with mean 42 points （ranging from 10 to 62） of the preoperative Harris score, the survival cases at the final follow-up had mean 84 points （ranging from 58 to 98）. One patient had mild pain in the hip. No revision of the acetabular or femoral component was undertaken during the follow-up. Normal rotational centre of most hips was recovered except 2 cases in which it was 0.8 mm higher than that in opposite side. All of them had a stable radiographic appearance. Progressive radiolucent lines were observed in Ⅰ,Ⅲ zones in 2 cases. One patient had a nonprogressive radiolucent line in zone Ⅲ. The cup prosthesis was obviously displaced （6 mm） in one patient, but had not been revised.
Conclusion： Particulate cancellous bone impaction grafting in combination with THA as a biological solution is an attractive procedure for acetabular reconstruction in patients with posttraumatic arthritis and bone loss after acetabular fracture, which can not only restore acetabular bone stock but also repair normal hip anatomy and its function.

Objective To observe the preliminary effects of the treatment for early non-traumatic osteonecrosis of the femoral head with Madopar. Methods Thirty-one patients with 48 hips of early stage (Ficat Ⅰ,Ⅱ) non-traumatic necrosis of the femoral head were treated with oral administration of Madopar since 2002. The disease was associated with consumption of alcohol in 16 cases with 27 hips; use of steroids in 10 cases with 13 hips; both consumption of alcohol and use of steroids in 2 cases with 4 hips; the remaining 3 cases, the condition was idiopathic. According to the criteria of Ficat et al., there were 4 hips in stage Ⅰ; 40 in stage Ⅱa and 4 in stage Ⅱb. Eighteen patients had received madopar for 10-28 months; 13 patients had been receiving the drug until now. Follow-up examinations were made by radiography, MRI and Charnley modified Merle d'Aubigne score. Results All patients were followed up for 12-84 months (average 27.8 months). The clinical symptoms improved in all cases. X-ray films showed that the bone density increased in nearly all the femoral heads, and 68.75%(33/48) of them maintained their shapes. The follow-up MRI showed their necrotic indices had decreased. The rate of clinical satisfaction was 91.67%(44/48), and the successful rate of treatment was 72.92%(35/48), and the collapse rate of early stage necrosis of the femoral head is 27.08%(13/48). Conclusion The preliminary results showed that madopar could prevent or delay collapse of the femoral head in early stage of osteonecrosis.

Comparison of severe trauma care effect before and after advanced trauma life support training

Objective： To study the emergency care effect of in-hospital severe trauma patients with the injury severity score （ISS）≥ 16 after medical staff received advanced trauma life support （ATLS） training.Methods： ATLS training was implemented by lectures,scenarios, field practices, and examinations. The clinical effect of in-hospital severe trauma care was compared 2 years before and after ATLS training.Results： During 2 years （from January 1, 2004, to December 31, 2005） before ATLS training, 438 cases of severe trauma were admitted and treated emergently in our department. Among them, ISS score was 28.6±7.8 on average, and 87 cases died with the mortality of 19.9%. The duration in emergency department and from admission to operation were 69.5 min±l 1.5 min and 89.6 min±9.3 min respectively. Two years （from January 1,2007, to December 31, 2008） after ATLS training, 382 cases of severe trauma were admitted and treated. The ISS was 25.3 ±6.1 on average and 62 cases died with the mortality of 15.1%. The duration in emergency department and from admission to operation were 47.8 min±10.7 min and 61.5 min±9.9 min respectively. The ISS score showed no significant difference between the two groups （P＞0.05）, but the mortality, the duration in emergency department and from admission to operation were markedly decreased after ATLS training and showed significant difference between the two groups （P＜0.05）.Conclusion： ATLS course training can improve the emergency care effect of in-hospital severe trauma patients,and should be put into practice as soon as possible in China.

Cementless Bipolar Hemiarthroplasty for Unstable Intertrochanteric Fractures in Elderly Patients

Background

Bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients is a viable option that can prevent the complications of an open reduction, such as nonunion and metal failure. This study evaluated the clinicoradiological results of cementless bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients.

Methods

Forty hips were followed for more than 2 years after cementless bipolar hemiarthroplasty using a Porocoat® AML Hip System. The mean age was 78.8 years and the mean follow-up period was 40.5 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using a range of indices.

Results

At the last follow-up, the mean Harris hip score was 80.6 points. There were one case of hip pain and one case of thigh pain. Twenty-four cases (60%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 23 cases (57.5%) of fixation by bone ingrowth and 17 cases (42.5%) of stable fibrous fixation. There were no cases of osteolysis. Eleven cases (27.5%) of new bone formation were found around the stem. All stems were stable without significant changes in alignment or progressive subsidence.

Conclusions

The short-term results of cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures were satisfactory.     

Operative treatment of hip fractures in patients receiving hemodialysis

Fifteen hips in 13 patients with hip fracture were treated in patients receiving hemodialysis for chronic renal failure. There were four intertrochanteric and 11 femoral neck fractures. 10 of the 11 femoral neck fractures and one of the four intertrochanteric fractures were treated with cemented bipolar hemiarthroplasty. Two intertrochanteric fractures fixed with sliding compression screws. External fixation was used for stabilization in two patients who had femoral neck and intertrochanteric fractures. Two intertrochanteric fractures that were treated with sliding hip screw showed radiological union postoperatively at the 6th month. Of the 11 hemiarthroplasty, four hips developed aseptic loosening (36%). According to Harris hip score grading system, three (37.5%) poor, two (25%) fair, two (25%) good and one (12.5%) case had excellent outcome in the hemiarthroplasty group. The survival of dialysis patients with a hip fracture is markedly reduced. Initial treatment of hemiarthroplasty allows early mobilization and prevents revision surgery.     

Cementless Bipolar Hemiarthroplasty Using a Hydroxyapatite-Coated Long Stem for Osteoporotic Unstable Intertrochanteric Fractures

Treating senile osteoporotic patients with unstable hip fractures remains a challenge. We evaluated the results of 87 cementless bipolar hemiarthroplasties using an extensively hydroxyapatite-coated long stem for unstable intertrochanteric fractures in senile patients. Sixty-one hips were followed for a minimum of 2 years (mean, 36 months) postoperatively. The mean Merle d'Aubigne and Postel hip score was 14.7 points (12-18). Two hips were reoperated because of infection. Of the remaining 59 hips, 48 were included in the radiographic analysis. Although cortical porosis around the stem was seen in 18 hips, there was no loosening or osteolysis. Cementless bipolar hemiarthroplasty using an extensively hydroxyapatite-coated long stem is a useful option for the treatment of unstable intertrochanteric fracture in senile patients with severe osteoporosis.
