Proximal femoral nail anti-rotation (PFNA) with a lag screw that is shaped like a spiral blade shape is an orthopedic implant to fix trochanteric fractures of the proximal femur. In addition the reason of the biomechanical advantages, PFNA widely been used recently. We report an 83-year-old man with excessive sliding of the helical blade and a femoral neck fracture after AO/OTA type A2 intertrochanteric fracture, which was fixed with a PFNA.

OBJECTIVE: To summarize the research progress on the evaluation methods of head-neck nail positions in femoral intertrochanteric fractures. METHODS: The literature about the evaluation methods of head-neck nail positions for femoral intertrochanteric fractures in recent years was extensively reviewed, and research progress in the aspects of evaluation methods, clinical applications, and limitations were summarized. RESULTS: The position of head-neck nails in femoral intertrochanteric fractures is closely related to postoperative complications of head-neck nail cutting. Currently, the tip-apex distance (TAD) and femoral head zoning are widely used to evaluate the position of head-neck nails. The main opinion in the literature is that the use of TAD and femoral head zoning can effectively reduce the incidence of head-neck nails cutting. Parker's ratio, as one of the evaluation methods, has been controversial in subsequent studies and has not been widely used in clinical practice. The TAD as referenced to the calcar (CalTAD), which was modified based on TAD, has been gradually accepted by the clinic, but whether it is better than the TAD has not yet been conclusively determined. In recent years, new evaluation methods have been proposed to supplement the previous evaluation methods, such as the tip-neck distance ratio (TNDR) and the standardized TAD (STAD) to avoid the limitations of the TAD and the CalTAD by the volume of the femoral head, and the axis-blade angle (ABA) to supplement the direction of the head-neck nails channel, but at present the clinical application is relatively underutilized, and the validity of the method needs to be further verified. CONCLUSION Currently, there are many methods for evaluating the position of head-neck nails in femoral intertrochanteric fractures, TAD<25 mm combined with head-neck nails placed in the middle-middle quadrant or lower-middle quadrant of the femoral head division is currently a highly recognized assessment in the literature, but the optimal assessment is still controversial, and further research needs to be studied.

Cannulated screw fixation is a widely accepted surgical method for management of fractures of the neck of femur especially in patients with poor premorbid conditions, minimally displaced fractures and those from a younger age group. A five year retrospective study was carried out in 53 consecutive patients between 2006 to 2010 to determine the pattern of injuries, management, outcomes and the associated predictive factors.All the patients underwent cannulated screw fixation, with 37 (69.8%) having had surgery within 24 hours and the remaining 16 (30.2%) 24 hours after the initial injury. All patients were followed up to union of fractures and complications thereafter if any. Good outcome was observed in 43 (81.1%) patients leaving only 10 (18.9%) patients with a poor outcome, of whom nine developed avascular necrosis (90%) and one non-union (10%). We found no significant relationship between the incidence of avascular necrosis and age of patient, fracture displacement, numbers of cannulated screws used, fracture reduction acceptability and anatomical location of the fracture. The time interval from injury to surgery and the presence of posterior comminution did seem to influence the rate of avascular necrosis but due to the small number of patients, was not statistically significant.We conclude that cannulated screw fixation is a viable option of treatment for fractures of the neck of femur.

PURPOSE: To evaluate the reliability of Singh index (SI) values, determined on image software processed digital radiographs in elderly patients with proximal femoral fractures, with respect to its value as a simple and inexpensive method to evaluate osteoporosis in acute trauma situations. MATERIALS AND METHODS: The authors retrospectively reviewed 210 patients (98 femur neck fractures, 112 intertrochanter fractures) treated between March 2005 and March 2009. Preoperative digital radiographs of each patient were assessed by four observers to determine SI values. The reliability of SI was expressed in terms of intraobserver and interobserver agreements in pairs using Fleiss's overall Kappa, Stuart's tau-c index, and Kendall's coefficiency of concordance. RESULTS: Fleiss's overall kappa values for intraobserver agreement ranged from 0.278 to 0.586 (mean, 0.452) and did not reach good reliability overall. Fleiss's overall kappa values for interobserver agreement ranged from 0.120 to 0.241 (mean, 0.180), and thus, did not reach acceptable reliability. CONCLUSION: The result suggest that the image adjustment tools provided by digital radiography cannot improve the usefulness of SI as a simple and inexpensive method of assessing the osteoporosis. Therefore, the reliability of SI good enough to be used for clinical and research work is questionable.

PURPOSE: This study was accomplished to evaluate the clinical & radiological results of cementless total hip arthroplasty using a fully hydroxyapatite-coated femoral stem after follow up of at least, 2 years. MATERIALS AND METHODS: Thirty one hips in 28 patients, who underwent primary total hip arthroplasty using a fully hydroxyapatite-coated femoral stem between september 2007 and May 2009, were followed up for more than 2 years after surgery. The average age of patients was 67 years old, and the average duration of follow up was 35 months. Preoperative diagnosis was 17 cases of osteonecrosis and 10 cases of femoral neck fracture. Clinical evaluation was done by Harris hip score (HHS). Radiological evaluation was done in terms of stability of components, subsidence of femoral stem and occurrence of osteolysis. RESULTS: The average of HHS improved from 34.3 preoperatively to 82.6 at final follow-up. Radiologically, fixation by bony ingrowth was 23 cases(74%) and fibrous ingrowth was 8 cases(26%). Subsidence was within 2-4 mm and occurred within 6 weeks in all 5 cases. There were 4 cases of intra-operative femoral fracture, 1 case of superficial infection. CONCLUSION: Short-term clinical and radiological results of cementless total hip arthroplasty using a fully hydroxyapatite-coated femoral stem were not good enough. Radiologically, bony ingrowth were no more than 74%. Therefore, longer-term follow up would be necessary.

We studied 16 cases intracapsular pressure in displaced fracture of femoral neck(Garden stage III, IV), the pressures were measured range between 12-62 mmHg(mean, 23.4 mmHg). Aspirated blood amount from hip joint did not exceed 3cc, this amount not correlate with intracaspsular pressure. Of 10 cases examined scintimetry, 2 had incressed uptake after aspiraton, it is suggested that early decompression of hemarthrosis in femur neck fracture regaredless of displacement may be considered.

PURPOSE: The Garden classification by which femur neck fracture is classified and the Boyd-Griffin classification by which trochanteric fracture is classified are studied on the reproducibility, repeatability, interobserver's and intraobserver's reliability and then reliability. MATERIALS AND METHODS: 56 cases in femoral neck fracture and 60 cases in trochanteric fracture who were operated from May 1999 to December 2003 were classified by three observers who are hip surgeon, orthopaedic surgeon and senior residentship doctors three times. Femur neck fracture was classified by Garden's method which used commonly and trochanteric fracture was classified by Boyd-Griffin method which is classified by the pattern of fracture and degree of comminution. We got the interobserver's and intraobserver's Kappa score using the Stata 7.0 statistically. The statistical analysis was made by Stata 7.0. RESULTS: Garden classification in femur neck fracture showed moderate agreement in intraobserver reliability and fair agreement in interobserver reliability. Boyd-Griffin classification in trochanteric fracture showed substantial agreement in intraobserver reliability and moderate agreement in interobserver reliability. CONCLUSION: Boyd-Griffin classification showed over moderate agreement but Garden classification showed fair agreement, so using Garden classification in femur neck fracture has some problem in reliability and application.

PURPOSE: This study aims to determine the correlation between the fracture patterns and the complications in patients with femoral neck fracture treated with internal fixation. MATERIALS AND METHODS: The study comprises 45 patients with femoral neck fracture treated with multiple screws or compression hip screw between May 2008 and April 2012. The mean age was 48 years at the time of the surgery and the mean duration from initial injury to surgery was 20 hours. The fracture patterns were identified according to the anatomical location, the Garden classification and the Pauwels classification. The occurrence of nonunion and avascular necrosis were reviewed with clinical results including Harris hip score and Lunceford hip function test. The correlation between the fracture pattern and occurrence of complications were analyzed. RESULTS: Fracture site union was achieved in 40 hips with the average union time of 17 weeks. Five nonunions occurred which showed high likelihood to occur in subcapital type, displaced (Garden stage III or IV) and Pauwels type III fractures (P<0.05). Avascular necrosis was developed in 10 hips which was mostly in subcapital type and Pauwels type III fracture but no statistical significance was found (P>0.05). The mean Harris hip score was 91 points, and Lunceford functional results were excellent in 15 hips, good in 24, fair in 4 and poor in 2. CONCLUSION: There was high risk of nonunion in subcapital type fracture, displaced fracture (Garden stage III and IV) and vertically oriented fracture (Pauwels type III). Careful attention is needed in these fracture types.

PURPOSE: To evaluate the difference between dynamic hip screw and cannulated screw for stability, complication and patient s functional recovery in intracapsular fracture of femoral neck. MATERIALS AND METHODS: Eight-four patients were randomly assigned into dynamic hip screw fixation and cannulated screw fixation groups. Clinical information included age and sex distribution, operation time, total blood loss, interval from injury to operation, etiology of fracture, associated fracture, and functional outcome. Preoperative X-ray information included fracture type by Garden stage, Singh index, and posterior comminution. Postoperative information included quality of reduction, pin and screw position, Garden alignment index, evidence of union, complication and failure. RESULTS: No difference was noted between the two fixation methods regarding gender, initial fracture displacement, postoperative reduction or position of the fixation device, functional outcome using Robinson's method, and complication. In operation time and total blood loss, however, cannulated screw fixation group was significantly lower (P<0.05). CONCLUSIONS: Therefore, to decrease operation time and blood loss, cannulated screw fixation was considered to be more useful as a fixation method in a intracapsular fracture of femoral neck.
