Abstract
Objective: The aim of this study was to investigate the impact of occupation in patients with transient osteoporosis of the hip (TOH). The study also compares two different types of management for this condition: conservative treatment and surgical drilling.

Methods: This was a retrospective case series study. The medical records for patients diagnosed with TOH at our institution within the period 2012-2017 were retrieved. General demographic data, clinical features, and diagnostic modalities were obtained. In addition, management procedures and their associated prognostic factors were acquired. The effectiveness of these procedures was assessed by the number of days of sick leave, the time needed for full recovery and the number of recurrences of TOH. Also, pain responses at 24 hrs, 48 hrs, and at 1 week were estimated subjectively through a «pain score» out of 10, and objectively through the degree of improvement in daily activity. The patients had a regular follow-up at 4- to 6-week intervals.

Results: In total, 15 cases of TOH, 14 men and one woman, were enrolled in the study. The mean age of the patients was 41 years (range 26-59 years). Out of the 15 cases, nine were healthcare professionals (eight physicians and one nurse). Ten patients underwent hip drilling for core decompression and five patients were treated conservatively. The time needed for full recovery was 5.8 weeks for those who underwent drilling, and 48.3 weeks for three patients receiving conservative treatment. The other two patients who were treated conservatively had not achieved full or near-full recovery at the time of reporting this study.

Conclusion: Physicians may be at increased risk of developing TOH. Further studies should be conducted to examine the role of this occupation as a risk factor. In addition, hip drilling should be considered as an effective treatment modality, especially in those patients who seek a faster recovery.
