Abstract
Purpose
To analyse and compare the functional and radiological outcome of different methods of surgical management of humerus shaft fractures in 30 patients treated by conventional open reduction and internal fixation (ORIF) or minimally invasive plate osteosynthesis (MIPO).
Methods
This prospective interventional study was conducted among 30 patients by dividing into two equal groups over one year and six months. All patients were followed up for a minimum of at least six months. Radiological outcome was assessed using fracture union in serial radiographs and functional outcome was measured using DASH scoring.
Results
The majority of patients (26.7%) were between 18 to 30 years, overall mean age was 44.4 years, most of the patients (50%) had 12A3 AO type fractures, and 73.3% of patients had injuries following two-wheeler road traffic accidents. On comparing multiple factors, we found a statistically significant reduction of intra-operative blood loss in MIPO compared to ORIF. Though time taken for fracture union, functional outcome and complication rate were better in MIPO when compared to ORIF, these differences were not statistically significant. two patients in the MIPO group and one patient in the ORIF group had a peri-implant fracture following slip and fall again within the study period and underwent Revision plating. Excluding cases of peri-implant fractures, out of 13 patients in the MIPO group, only one patient developed fracture non-union. Of 14 patients in the ORIF group, three developed fracture non-union.
Conclusion
MIPO is a safe, reproducible, efficient and good if not a better alternative to ORIF as it offers good radiological and functional outcomes with advantages of minimal soft tissue damage, minimal blood loss, better cosmesis, no incidence of radial nerve palsy and with few concerns such as the need for fluoroscopy, and a learning curve.
期刊介绍:
International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters.
Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
