Abstract:
INTRODUCTION :
Humerus shaft fractures are common orthopedic injuries, often resulting from trauma
and the choice of treatment remains a topic of debate. Intramedullary interlocking
nailing is a minimally invasive surgical technique that provides excellent bio-
mechanical stability, particularly in diaphyseal fractures and facilitates early
mobilization. This prospective study evaluates the functional outcomes of
intramedullary interlocking nailing in the treatment of Shaft humerus fractures.
OBJECTIVES :
- To examine the functional results of intramedullary interlocking nails used to treat
closed shaft humerus fractures.
- To study the common complications associated with humerus nailing, such as non-
union rate, infection, rotator cuff dysfunction and need for secondary procedures.
MATERIALS AND METHODS :
The present study involved 40 cases with shaft humerus fractures treated with
Intramedullary Interlocking nails. Patient were followed up for minimum of 6 months.
Inclusion criteria were patients of age above 18 years and below 70 years with closed
and segmental fractures. Functional outcome evaluation was done using DASH score.
Radio logical union, intra-operative data, and complications were documented.
RESULTS :
The study observed fracture union in 95% of cases, with an average time to union of
10-16weeks.At the final follow-up, the average mean DASH score was 16.51,
indicating adequate elbow, arm, and shoulder function. Out of 40 patients, 6(15%)
patients had excellent functional outcomes,26(65%) patients had good results, 6(15%)
patients had fair outcome and with 5% having poor outcome which needed secondary
procedures for union.
CONCLUSION :
Intramedullary interlocking nailing is an effective and reliable method for managing
shaft humerus fractures, providing excellent functional outcomes and high rates of
fracture union and acceptable complications. Early mobilization and minimal surgical
morbidity make it a good option. Intamedullary interlocking nailing for humerus shaft
fractures results in significant functional recovery, as evidenced by improved DASH
scores at 6 months. This highlights its efficacy as a minimally invasive treatment
option with favorable long-term outcomes.
