Abstract
Background: Simple bone cyst is a common benign lesion in the proximal humerus,
especially in prepubertal children. Up to 75 percent of patients with the bone cyst have a
pathologic fracture and the most significant complication is recurrent pathologic fracture.
Since the process of spontaneous healing of these fractures is rare, treatment is required.
Ideal treatment for simple bone cyst should stabilize pathologic fractures, assist healing
and provide a quick return to normal activity with reduced complication and recurrence.
Methods: In this descriptive case series study, 24 patients with simple bone cysts of the
humerus were selected for retrograde flexible intramedullary nailing from the lateral
cortex of the distal humerus, since 2000 to 2005 at Imam Khomeini Hospital, Tehran.
The mean age of the patients was 14.4 years, ranging from 6-39 years. Results were
evaluated by plain radiography using the classification system of Capanna et al.
Results: The mean duration of follow up for 23 of the patients was 31 (9-51) months.
One patient with short-term of follow-up was excluded. Of these patients, 91.3% were
healed either completely (65.2%) or with residual minor defect (26.1%). Only one cyst
(4.3%) persisted with no response to treatment and one patient (4.3%) had a recurrence of
the cyst. However, there was no instance of recurrent pathologic fracture among these
patients.
Conclusion: This study shows that flexible intramedullary nailing is an effective
treatment for humeral simple bone cysts that reduces the chance of complication,
recurrence of cyst or pathologic fracture. This technique provides sufficient stability for
quick return to normal activity.

Abstract
Background: Shoulder hemiarthroplasty is one of the established methods for management of proximal humerus fractures particularly in the types with more displacement so that fixation is not possible. Successful treatment is a challenge for shoulder surgeons especially in elderly patients. The aim of this study is to investigate the functional results and prognostic factors on shoulder hemiarthroplasty.
Methods: Thirty nine patients operated by one shoulder surgeon in Imam Khomeini and Shariati Hospital in Tehran, Iran, from October 2005 to February 2009 were included in this study and followed postoperatively for at least one year. Mean (±SD) age was 49.7±14.3 years. Functional results were measured by constant score and pain was scored using visual analogue score. The relationship between factors such as age, injury to surgery interval, radiographic parameters and functional results were assessed. Results: Mean (±SD) constant score was 61.9±20.2. The age and injury to surgery interval showed a reverse correlation with constant score (p<0.05). There was a significant correlation between constant score and acromiohumeral interval (r=0.53) and head to tuberusity distance (-0.59). Median VAS score was 4.5 (interquartile range: 2- 5.2) that had a direct correlation with age (r=0.38) and injury to surgery interval (r=0.55) (p<0.05).
Conclusions: Shoulder hemiarthroplasty should be performed in minimal delay from injury and this operation should be performed by an experienced shoulder surgeon to create the best anatomic position of prostheses. Careful rehabilitation particularly in older patients is very important to improve results.

Abstract
Background: The supratrochlear foramen (STF) is an important and relatively common anatomic variation in the lower end of the humerus in humans. In recent years it has become clear that STF should be emphasized because anatomical knowledge of STF is useful for anatomists, anthropologists, orthopedic surgeons, and radiologists. The anatomical structure of the humerus may play an important role in the intramedullary fixation thereby stressing the need of prior anatomical knowledge and preoperative planning in the presence of variations like STF in the distal end of the humerus. This study focuses on STF in the distal of the humerus bone and as well as the intertubercular sulcus (ITS) in the Iranian population.
Methods: This study was performed on 57 adult human humeral bones regardless of their gender at Arak University of Medical Sciences in Iran that it was done from October 2014 to March 2015. A total of 57 dried humerus (27 right side and 30 left side) were examined to determine the presence of supratrochlear foramen and septum. They were free from any pathological changes and fractures. The STF was analyzed for morphology and morphometric correlation.
Results: STF was found in only four cases (6.8%) of the humerus bones, two cases (3.4%) on the left and two cases (3.4%) on the right. The shape of the STF was oval, round and triangular. The mean STF transverse diameter in the right bones was 2.60±2.68 mm and in the left bones 0.57±0.31 mm and the mean vertical STF diameter in the right and left bones were 1.75±1.76 mm and 0.55±0.07 mm, respectively.
Conclusion: There was no significant difference in the shape of the STF and its number in the right and left bones. Twenty-seven bones (47%) out of 53 bones without supratrochlear foramen (STF) had septum.
