Hemiarthroplasty or total hip arthroplasty for the treatment of a displaced intracapsular fracture in active elderly patients: 12-year follow-up of randomised trial.

AIMS: Our aim was to analyse the long-term functional outcome of two forms of surgical treatment for active patients aged > 70 years with a displaced intracapsular fracture of the femoral neck. Patients were randomised to be treated with either a hemiarthroplasty or a total hip arthroplasty (THA). The outcome five years post-operatively for this cohort has previously been reported. We present the outcome at 12 years post-operatively. PATIENTS AND METHODS: Initially 252 patients with a mean age of 81.1 years (70.2 to 95.6) were included, of whom 205 (81%) were women. A total of 137 were treated with a cemented hemiarthroplasty and 115 with a cemented THA. At long-term follow-up we analysed the modified Harris Hip Score (HHS), post-operative complications and intra-operative data of the patients who were still alive. RESULTS: At a mean follow-up of 12 years (8.23 to 16.17, standard deviation 2.24), 50 patients (20%), 32 in the hemiarthroplasty group and 18 in the THA group, were still alive, of which 47 (94%) were women. There were no significant differences in the mean modified HHS (p = 0.85), mortality (p = 0.13), complications (p = 0.93) or rate of revision surgery (p = 1.0) between the two groups. CONCLUSION: In the treatment of active elderly patients with an intracapsular fracture of the hip there is no difference in the functional outcome between hemiarthroplasty and THA treatments at 12 years post-operatively.

Shoulder fusion in two patients with a long-standing proximal humerus resection.

With a "headless" humerus active abduction and elevation of the arm are hardly possible. Especially if the humeral head was removed because of an infection, shoulder fusion is often the only safe solution for this disabling condition. Large corticocancellous, autologous bone grafts are interposed between the thin humeral stump on one side and its broad glenoid-acromion counterpart on the other. A 4.5 narrow AO-plate stabilizes the fusion. The technique is described and the functional result of two patients is shown. Ten years after the operation, both patients were free of pain and very satisfied about the utility of the arm. The fusion had convincingly healed in the planned position. Shoulder fusion proved to be a safe and good solution for both our patients with a longstanding headless humerus. Ten years after the operation they were free of pain and had regained a useful arm.

A comparison of hemiarthroplasty with total hip replacement for displaced intracapsular fracture of the femoral neck: a randomised controlled multicentre trial in patients aged 70 years and over.

The aim of this study was to analyse the functional outcome after a displaced intracapsular fracture of the femoral neck in active patients aged over 70 years without osteoarthritis or rheumatoid arthritis of the hip, randomised to receive either a hemiarthroplasty or a total hip replacement (THR). We studied 252 patients of whom 47 (19%) were men, with a mean age of 81.1 years (70.2 to 95.6). They were randomly allocated to be treated with either a cemented hemiarthroplasty (137 patients) or cemented THR (115 patients). At one- and five-year follow-up no differences were observed in the modified Harris hip score, revision rate of the prosthesis, local and general complications, or mortality. The intra-operative blood loss was lower in the hemiarthroplasty group (7% > 500 ml), THR group (26% > 500 ml) and the duration of surgery was longer in the THR group (28% > 1.5 hours versus 12% > 1.5 hours). There were no dislocations of any bipolar hemiarthroplasty than in the eight dislocations of a THR during follow-up. Because of a higher intra-operative blood loss (p < 0.001), an increased duration of the operation (p < 0.001) and a higher number of early and late dislocations (p = 0.002), we do not recommend THR as the treatment of choice in patients aged ≥ 70 years with a fracture of the femoral neck in the absence of advanced radiological osteoarthritis or rheumatoid arthritis of the hip.

Treatment of malunited fractures of the ankle: A long-term follow-up of reconstructive surgery.

In this retrospective study, using the prospectively collected database of the AO-Documentation Centre, we analysed the outcome of 57 malunited fractures of the ankle treated by reconstructive osteotomy. In all cases the position of the malunited fibula had been corrected, in several cases it was combined with other osteotomies and the fixation of any non-united fragments. Patients were seen on a regular basis, with a minimum follow-up of ten years. The aim of the study was to establish whether reconstruction improves ankle function and prevents the progression of arthritic changes. Good or excellent results were obtained in 85% (41) of patients indicating that reconstructive surgery is effective in most and that the beneficial effects can last for up to 27 years after the procedure. Minor post-traumatic arthritis is not a contraindication but rather an indication for reconstructive surgery. We also found that prolonged time to reconstruction is associated negatively with outcome.

Tibial spine fractures: a long-term follow-up study of open reduction and internal fixation.

OBJECTIVE: To analyze the long-term (5-27 years) functional and radiologic results of surgically treated tibial spine fractures. DESIGN: Retrospective cohort study. SETTING: University hospital. PATIENTS AND METHODS: Forty-four surgically treated consecutive patients with 44 displaced tibial spine fractures were included in this study. All fractures were classified according to a modified Meyers and McKeever classification. There were 24 men and 20 women. The mean age at time of accident was 24 years (range 9-57 years). Sixteen patients had an open physis at the time of trauma. There were 36 patients with isolated fractures and 8 with multiple fractures. All patients were seen for a 1-year follow-up, and 37 patients (84%) were seen for a long-term follow-up visit. Functional results of these 37 patients were graded using the Lysholm, SF-36, and the Western Ontario and McMaster Universities scores. Radiologic results were graded using the Ahlbäck score. RESULTS: At 1-year follow-up, in all 44 patients, the fracture was fully healed. One patient (3%) needed revision of the osteosynthesis due to hardware failure, and in 1 patient (3%), a deep infection (purulent arthritis) developed that was treated by surgical irrigation. The median knee range of motion (ROM) after 1 year was 125 degrees (range 110-140 degrees). The ROM did not change significantly at long term. After a mean follow-up of 16 years (range 5-27 years), the median knee ROM was 130 degrees (range 115-140 degrees). As measured with an objective testing device, no statistically significant difference of anteroposterior stability between the injured and uninjured legs was found, with a mean difference of 1 mm (range -3.9 to 6.9 mm). The Lysholm score showed good to excellent results in 86% of the patients; the Western Ontario and McMaster Universities score showed a mean of 93 (range 40.63-100) points. The mean SF-36 general health score was 77 (24-99). The Ahlbäck score showed a moderate development of secondary osteoarthritis in 2 of the 37 patients (5%). The 16 patients with an open physis at the time of the operation did not develop axial malalignment at long term. CONCLUSIONS: Surgical treatment of tibial spine fractures offers the possibility to regain full stability of the knee joint and good long-term results after open reduction and internal fixation with low infection rates. Knee function is adequately restored in most patients with a minimal risk of developing secondary osteoarthritis.

Operative treatment of 109 tibial plateau fractures: five- to 27-year follow-up results.

OBJECTIVE: To analyze the long-term (5-27 years) functional and radiologic results of surgically treated fractures of the tibial plateau. DESIGN: Retrospective study. SETTING: University hospital. PATIENTS AND METHODS: Two hundred two consecutive tibial plateau fractures were included in this study. All fractures were classified according to both the AO and the Schatzker classification. There were 112 men and 90 women. The mean age at injury was 46 years (16 to 88). One hundred sixty-three patients had isolated fractures and 39 had multiple fractures. A 1 year follow-up was done in all 202 patients. One hundred nine of these patients also had an additional long-term follow-up visit. Functional results of these 109 patients were graded with the Neer- and HSS-knee scores. Radiologic results were graded with the Ahlbäck score. Statistical analysis was performed by means of the SPSS data analysis program. RESULTS: An uneventful union was present at the 1 year follow-up in 95% of the patients, along with a mean knee ROM of 130 degrees (range, 10-145 degrees). One hundred nine patients had a long-term follow-up visit after a mean period of 14 years (range, 5-27 years). The mean ROM at this time was 135 degrees (range, 0-145 degrees). Functional results showed a mean Neer score of 88.6 points (range, 56-100 points) and a mean HSS score of 84.8 points (range, 19-100 points). Monocondylar fractures showed statistically significant better functional results compared to bicondylar fractures. In 31% of the patients, secondary osteoarthritis had developed but was well tolerated in most (64% of the patients). Patients with a malalignment of more then 5 degrees developed a moderate to severe grade of osteoarthritis statistically significant more often (27% of the patients) compared to patients with an anatomic knee axis (9.2%; MWU, P = 0.02). Age did not appear to have any influence on the results. CONCLUSION: Long-term results after open reduction and internal fixation for tibial plateau fractures are excellent, independent of the patient's age.

Rating of internal fixation and clinical outcome in displaced femoral neck fractures: a prospective multicenter study.

The influence of precise surgical technique on the clinical outcome of internal fixation for displaced femoral neck fractures is an under-reported and potential confounding factor in randomized studies involving internal fixation as a treatment modality. Two experienced surgeons blindly rated internal fixation techniques on the perioperative radiographs of 102 patients selected for internal fixation in a prospective multicenter 2-year followup study. Overall technical, fracture reduction, and implant positioning ratings were given according to instruction. One or both raters assigned an inadequate overall rating in 25% of patients. There was a correlation with 2-year clinical internal fixation failure for overall technique and fracture reduction rating. Implant positioning did not correlate with 2-year internal fixation failure. Correlation increased if both raters agreed on inadequate technique. One inadequate rating indicated a problem could arise, whereas two inadequate ratings strengthened this problem likelihood. Adjudication of technique by independent rater(s) is useful, may have clinical implications, and should be performed routinely in future studies involving internal fixation in patients with displaced femoral neck fractures.

[Large variation in indications for internal fixation or arthroplasty in displaced femoral neck fracture; results of a questionnaire distributed among general surgeons in 20 hospitals]. / Grote variatie in indicaties voor interne fixatie of artroplastiek bij de gedislokeerde mediale collumfractuur; enquête onder algemeen chirurgen in 20 ziekenhuizen.

OBJECTIVE: To describe the treatment protocols for displaced femoral neck fractures in all 8 university hospitals (UH) and 12 general hospitals (GH). DESIGN: Descriptive; questionnaire. METHOD: Questionnaires were distributed to general surgeons who also perform traumatology surgery. They were requested to give succinct answers to questions about local protocol for the maximum permissible time interval between hip trauma and operation, indications for internal fixation and arthroplasty, operative technique and postoperative degree of weight-bearing in patients over 60 years of age with a displaced femoral neck fracture. RESULTS: Internal fixation and arthroplasty were performed within 24 and 48 hours respectively in 95% of all hospitals. A biological upper age limit of between 65 and 80 years old was the most commonly quoted indication for internal fixation in 70% of all hospitals. In 83% of GH dementia was considered an indication for arthroplasty as opposed to 0% in UH. Poor bone quality, immobility, comminution and inadequate reduction were incidentally quoted indications for arthroplasty. Rheumatoid arthritis, arthrosis and pathological fracture were contra-indications for internal fixation in all hospitals. Operative techniques for internal fixation and arthroplasty were similar in both UH and GH. After internal fixation, full weight-bearing was recommended in all UH and partial weight-bearing in 7 (58%) of GH. Following arthroplasty all protocols prescribed full weight-bearing. CONCLUSION: The variation in indications for internal fixation or arthroplasty reflects the lack of studies that demonstrate clearly which patient can be treated optimally with which treatment modality. There were few differences in the operative techniques of internal fixation and arthroplasty between the hospitals.

Internal fixation for displaced fractures of the femoral neck. Does bone density affect clinical outcome?

The results of meta-analysis show a revision rate of 33% for internal fixation of displaced fractures of the femoral neck, mostly because of nonunion. Osteopenia and osteoporosis are highly prevalent in elderly patients. Bone density has been shown to correlate with the intrinsic stability of the fixation of the fracture in cadaver and retrospective studies. We aimed to confirm or refute this finding in a clinical setting. We performed a prospective, multicentre study of 111 active patients over 60 years of age with a displaced fracture of the femoral neck which was eligible for internal fixation. The bone density of the femoral neck was measured pre-operatively by dual-energy x-ray absorptiometry (DEXA). The patients were divided into two groups namely, those with osteopenia (66%, mean T-score -1.6) and those with osteoporosis (34%, mean T-score -3.0). Age (p = 0.47), gender (p = 0.67), delay to surgery (p = 0.07), the angle of the fracture (p = 0.33) and the type of implant (p = 0.48) were similar in both groups. Revision to arthroplasty was performed in 41% of osteopenic and 42% of osteoporotic patients (p = 0.87). Morbidity (p = 0.60) and mortality were similar in both groups (p = 0.65). Our findings show that the clinical outcome of internal fixation for displaced fractures of the femoral neck does not depend on bone density and that pre-operative DEXA is not useful.

Open reduction and internal fixation of three and four-part fractures of the proximal part of the humerus.

BACKGROUND: Controversy persists concerning the preferred treatment of displaced fractures of the proximal part of the humerus. The present study was undertaken to evaluate the results of open reduction and internal fixation of three and four-part fractures of the proximal part of the humerus and the functional limitations of patients in whom avascular necrosis of the humeral head develops as a complication of this fracture. METHODS: We assessed the intermediate and long-term results for sixty patients with a three or four-part fracture of the proximal part of the humerus who had undergone open reduction and internal fixation with cerclage wires or a T-plate. The Constant score and a visual analog score for pain were calculated, and radiographs of the proximal part of the humerus were evaluated. RESULTS: After an average of ten years of follow-up, fifty-two patients (87%) had a good or excellent result on the basis of the Constant score whereas eight patients (13%) had a poor result. Fifty-one patients (85%) were satisfied with the result at the time of the most recent examination. Twenty-two patients (37%) had development of avascular necrosis of the humeral head, and seventeen (77%) of these twenty-two patients had a good or excellent Constant score. CONCLUSIONS: Open reduction and internal fixation with cerclage wires or a T-plate yields good functional results in most patients. This option should be considered even for patients with fracture-dislocation patterns that are associated with a high risk for avascular necrosis of the humeral head, as this complication did not preclude a good result.

[Medial femoral neck fracture. Controversies in treatment]. / Die mediale Schenkelhalsfraktur. Kontroversen in der Behandlung.

The treatment of the medial femoral neck fracture remains controversial until today. The goal of this paper is therefore, based on the literature, to show guidelines for optimal treatment: conservative treatment vs. operation, osteosynthesis vs. prosthesis, timing for osteosynthesis, open vs. closed reduction, choice of implant for osteosynthesis, postoperative treatment (weight bearing vs. non weight bearing), Pauwels-Osteotomy vs. prosthesis in cases op pseudarthrosis, femoral head prosthesis vs. total hip arthroplasty, bipolar vs. monopolar femoral head prosthesis, choice of classification. Further we want to point out which statements are evidence based and where we need further investigation.

Functional treatment after surgical repair of acute Achilles tendon rupture: wrap vs walking cast.

The aim of this study was to compare the clinical outcome for patients treated with walking cast immobilization and wrap early mobilization after surgical repair of acute Achilles tendon ruptures. A total of 39 consecutive patients with complete ruptures of the Achilles tendon were identified, treated, and functionally rehabilitated with either a walking cast or a wrap. Because the randomization was quasi-random, chi-square and t-tests were performed to compare the baseline characteristics. A statistically significant difference was present only for the injured side ( p<0.05). Therefore, groups were considered comparable for analysis of outcome. All patients were evaluated at an average follow-up of 6.7 years (range 5-8 years). Functional postoperative treatment with a wrap allowed a significantly shorter hospital stay ( p<0.05) as well as a shorter period to return to pre-injury sports level ( p<0.01) compared with treatment with a walking cast. According to the modified Rupp score, 91.3% of patients in the walking cast group had a good or excellent result, as did 93.8% in the wrap group ( p=0.9). Slight atrophy of the calf muscles was reported in 3 patients in the walking cast group (13.0%) and in 4 in the wrap group (25.0%). One re-rupture was reported in the walking cast group (4.3%). Functional treatment after surgical Achilles tendon repair is safe, and there is no increased risk of re-rupture or wound healing problems. Functional treatment with a wrap is preferable to treatment with a walking cast with respect to hospitalization time and return to sports.
