Summary

Hip excision surgery outcomes show varying mobility and pain levels. Electromyocinesigraphy revealed abnormal muscle activity patterns in operated legs and compensatory changes in non-operated legs.

Area of Science:

  • Orthopedic Surgery
  • Rehabilitation Medicine
  • Biomechanical Engineering

Background:

  • Femoral head and neck excision is a surgical procedure.
  • Post-operative functional outcomes require thorough evaluation.

Purpose of the Study:

  • To assess functional outcomes (walking, pain) after femoral head and neck excision.
  • To investigate muscle function using electromyocinesigraphy (EMG) in patients post-excision.

Main Methods:

  • Retrospective study of 47 patients (45 unilateral, 2 bilateral) with femoral head and neck excision.
  • Follow-up duration ranged from 6 months to 6 years.
  • Functional assessment included walking ability and pain levels; EMG was performed on 6 patients.

Main Results:

Related Experiment Videos

  • 55% walked well with one cane, 31% with two canes, 14% needed assistance.
  • 31% were pain-free, 55% experienced pain on fatigue, 14% had constant pain.
  • EMG showed no hip abductor innervation, high rectus anterior activity, abnormal erector spinae activity, and increased non-operated leg abductor activity.

Conclusions:

  • Femoral head and neck excision impacts gait and pain significantly.
  • Abnormal muscle activation patterns observed post-surgery suggest functional deficits.
  • Compensatory mechanisms in non-operated limbs are evident, highlighting the need for targeted rehabilitation.
