Introduction

Complication reporting and assessment is an important part of orthopaedic trials assessing new technologies. Because the reliability of the assessment by the treating surgeon compared to central review is still unknown, it was quantified in this study and possible patterns were identified.

Materials and methods

176 patients with trochanteric fractures, treated with a trochanteric nail, were included in a prospective multicenter study. Surgeons were encouraged to report honestly every single potential complication, to rate severity, most likely cause, relation to implant, and to report the outcome of the complication. After 1-yr follow-up, 3 experienced orthopedic surgeons reassessed independently the same variables (agreement determined using kappa coefficient). Discrepancies were resolved by consensus.

Introduction

Proxy assessment of health-related quality of life (HRQoL) can be an alternative to self reporting in elderly patients with cognitive or physical impairment. However, over- and underestimation by the proxies is reported. The aim of the present study was to examine the agreement of HRQoL answers between old Japanese patients and their close relatives.

Materials and methods

In a clinical study about trochanteric fractures, HRQoL was assessed using the SF36v2. A sample of 27 questionnaires were completed via telephone interview twice on the same day: once by the patients themselves, and once by a close relative. Assessments were performed at either 6 or 12 mo after surgery. The reliability of the SF36v2 dimensions and of the 2 component summary measures was assessed by Intraclass Correlation Coefficients.

Introduction

When translating the principle of intramedullary nailing for trochanteric femoral fractures to Asian patients, design modifications made to adjust for anatomic differences resulted in an PFNA Asia. The primary endpoint of this study was the rate of complications attributable to fracture fixation.

Material and methods

A prospective multicenter case series was performed; 176 patients with a median age of 84 with unstable trochanteric fractures treated with a PFNA Asia were included and followed for one year postoperatively. Complications were reviewed by a complication review board (CRB). Intra- and postoperative fracture fixation complications are presented according to type and incidence proportions (risk).

Introduction

Tip apex distance (TAD) is reported as a predictor for cut outs of lag screws in the treatment of intertrochanteric fractures, and surgeons are adviced to strive for TAD within 20 mm. However the definition of neck axis and the limb position of lateral radiograph are not clearly described in the original literature. We propose the refined TAD by defining these factors. The objective of this study was to analyze the interobserver agreement of this refined TAD.

Materials and Method

X rays of 130 cases of unstable trochanteric fractures were used for the analysis of the refined TAD. In the refined TAD, neck axis was defined as the line between the center of femoral head and midpoint of narrowest part of the femoral neck, and lateral radiograph was taken with hip flexion 90 degrees and abduction 45 degrees. The refined TAD was independently measured by 2 experienced (observer 1,2) and 2 inexperienced (observer 3,4) orthopaedic surgeons who were trained with the new method before the measurement. Intraclass correlation coefficient (ICC [2,4]) was calculated to assess the interobserver agreement.

Introduction

For the increasing number of frail elderly patients in Japan, mobility is crucial to stay independent and maintain quality of life. After failure reports with standard implants, a prospective multicentre study was performed to evaluate whether an implant designed for Asians enables rapid recovery after unstable trochanteric fractures.

Materials and methods

Patients with an AO 31A2 or A3 fracture sustained less than 7 days before fracture fixation with the Asian version of the Proximal Femoral Nail Antirotation. Those with severe dementia and bedridden or confined to a wheelchair were excluded. Outcome parameters were quality of life (SF36v2, EQ5D), mobility (Parker Mobility score PMS) and range of motion (ROM).

Background: The interpretation of safety data from clinical studies such as complication risks requires clear definition of targeted and documented complication events. In addition a standardized classification of complications is required to allow appropriate comparison of safety data between studies and treatment groups. This presentation highlights a proposal for a standardized management and classification of complication data to initiate and seek consensus among trauma surgeons active in clinical documentation and research.

Methods: Complication events are examined regarding their timing of occurrence as well as their potential causal inter-relationship for any given patient. While independent events are numbered sequentially, directly associated events (e.g. a fracture collapse and implant screw perforation into a joint) receives the same complication number. Complications are described and categorized according to a pre-defined list of anticipated complication types, or as un-anticipated complications. They are further classified as local or general; local complications occur at or directly around the injuries and are further classified as being “Implant/Surgical procedure”, “Bone/Fracture” or “Soft tissue/Wound” events. Information regarding their operative and/or non-operative treatment and their outcome is recorded. Further assessments are made regarding their seriousness, their relation to the implant used. Final classification of complication events is better determined after independent review by a panel of experienced clinicians.

Results: Our classification process was applied successfully to a series of clinical studies at our department. In a study of 185 distal radius fractures treated by LCP, at least one complication occurred in 21 patients, and in seven cases there was a combination of associated events (e.g. one CTS with tendon rupture). Complication risks ranging from 0% to 11.4% were noted depending on which complications and time frames were considered. There was no risk to obtain a LCP implant specific related complication, whereas the risk for a local complication within 6 months after surgery was 6% (95% CI: 3% – 11%).

Conclusions: This management and classification system proved valuable in the documentation and analysis of safety data from clinical studies. It facilitates communication and understanding of definitions between clinicians, as well as allows a prompt, standardised and accurate analysis and reporting of complication events and risks. We encourage other clinical researchers and professionals to participate in the further development and acceptance of a universal classification system for complications in traumatology and orthopaedics.

Background: The nature and frequency of complications during or after orthopaedic interventions represent critical clinical information for safety evaluations, which are required in the development or improvement of medical procedures and devices. However, neither uniform definitions nor established classifications about the reporting of complications exist. So complication reporting, even in orthopaedic trials is still up to the surgeons perception and understanding. The goal of this systematic review was to check whether essential data are consistently provided by the authors in the assessment of incidence, severity and characteristics of complications related to orthopaedic interventions in randomized controlled trials.

Methods: Five major, peer-reviewed orthopaedic journals were screened for published randomized controlled trials (RCTs) between January 2006 and July 2007. All relevant papers were obtained, anonymized and evaluated by two external reviewers. A checklist consisting of three main parts: definition, evaluation and reporting was developed and applied for the assessment of complication reporting in RCTs. The results were stratified for the main area of the trial.

Results: One hundred and twelve RCTs meeting our inclusion criteria were identified. The majority of RCTs (n = 73) reported on surgical treatment methods, with most of the trials focussing on arthroplasty (38%); surgical fracture treatment and other surgical interventions accounted for 13% each. Although complications were included as trial outcomes in two thirds of the studies, clear definitions of anticipated complications were provided at least partly in only two trials of fracture treatment and six other trials. It remained unclear whether authors considered the specific events “death”, “mal-union”, “impaired function” and “re-operation” as complications; “impaired function” was not considered as a complication in 93% of the trials and “re-operation” events were considered in only 50% of the trials dealing with surgical fracture treatments. In 83% of RCTs, the identity of the person or group assessing the complications was unknown and in a further 8%, this process was implemented by the treating surgeon. This review did not identify any trial involving a Data Safety Review Board for assessment and classification of complications.

Conclusions: Due to the lack of homogeneity among the published trials, improvement in the reporting of complications is necessary. A standardized protocol for assessing and reporting complications should be developed and endorsed by professional organizations and most importantly, clinical investigators.
