Osteoporosis associated with pregnancy and lactation is a rare disease that can cause osteoporotic vertebral compression fracture (OVCF).Patients usually complain of severe back pain, which is easily mistaken for pain due to pregnancy, childbirth, and lactation, making a rapid diagnosis and treatment difficult. The authors diagnosed OVCF related to pregnancy and lactation through a physical examination, simple radiography, whole-body bone scan, magnetic resonance image, bone marrow density, and blood tests in a 29-year-old female patient and a 31-year-old female patient who presented with low back pain. This paper reports two cases of symptom improvement through a teriparatide injection, wearing thoracic lumbar sacral orthosis and taking calcium and vitamin D with a review of the literature.

Osteonecrosis of the femoral head usually affects young or middle-aged adults and frequently leading to femoral head collapse and hip arthritis. This review reports the updated treatments of the disease.

Medial meniscal root tears have been repaired using various methods. Arthroscopic all-inside repair using a suture anchor is one of the popular methods. However, insertion of the suture anchor into the proper position at the posterior root of the medial meniscus is technically difficult. Some methods have been reported to facilitate suture anchor insertion through a high posteromedial portal, a posterior trans-septal portal, or a medial quadriceptal portal. Nevertheless, many surgeons still have difficulty during anchor insertion. We introduce a technical tip for easy suture anchor insertion using a 25° curved guide and a soft suture anchor through a routine posteromedial portal.

PURPOSE: Hip fractures in hemodialysis patients are accompanied by high rates of complications and morbidities. Previous studies have mainly reported on nonunion and avascular necrosis of femoral neck fractures in this patient group. In this study the complication and clinical results of hemodialysis patients with intertrochanteric fractures treated with proximal femoral intramedullary nailing have been investigated through comparison with patients with normal kidney function. MATERIALS AND METHODS: Forty-seven patients were included; the hemodialysis group (n=17) and the control group with normal kidney function (n=30). The medical history and clinical findings including preoperative and postoperative blood examinations, radiological examinations and ambulatory status (measured using the Koval score). The rate of complications and morbidities were also investigated and compared. RESULTS: Preoperative hemoglobin/hematocrit was lower but a significant increase in partial thromboplastin time was observed in the hemodialysis group. The amount of bleeding/transfusions were higher and operative time was longer in the hemodialysis group. Upon radiologic examination, there was no significant difference in rate of unstable fracture and nonunion between the two groups. However the postoperative Koval score was significantly worse and the odds ratio of inability to walk after surgery was 13.5 times higher in the hemodialysis group. CONCLUSION: There was no significant difference in radiological results, but the risk of inability to walk after surgery was 13.5 times higher in the hemodialysis group. Hemodialysis patients have more morbidities and are hemodynamically unstable therefore require special attention. Accurate reduction and firm fixation is required and attentive postoperative rehabilitation is needed.

STUDY DESIGN: Retrospective analysis. OBJECTIVES: To determine the relationship between pelvic tilt and lumbar disc degeneration. SUMMARY OF LITERATURE REVIEW: The shape and the spatial orientation of the pelvis determine the organization of the lumbothoracic spine. The purpose of our study was to determine the relationship between pelvic tilt and lumbar disc degeneration. MATERIALS AND METHODS: Sixty patients over 50 years of age who had undergone lumbar spine magnetic resonance imaging were recruited. In individuals between 41 and 60 years of age, the normal pelvic tilt is 14°. Patients were divided into a low pelvic tilt (PT) group (<14°) and a high pelvic tilt (PT) group (≥14°). Lumbar disc degeneration was graded from I to V according to the Pfirrmann grade. We defined grades IV and V as high-grade degeneration and the others as low-grade degeneration. Radiologic parameters and lumbar disc degeneration were compared between these 2 groups. RESULTS: In the low PT group, the average degeneration grade of each lumbar segment was 2.61 in L1-L2, 2.61 in L2-L3, 3.00 in L3-L4, 3.39 in L4-L5, and 3.84 in L5-S1. The corresponding grades in the high PT group were 2.34 in L1-L2, 2.62 in L2-L3, 3.07 in L3-L4, 3.76 in L4-L5, and 3.55 in L5-S1. The grade of degeneration of the high PT group was significantly higher than that of the low PT group for L4-L5 (p=0.031). High-grade degeneration of the L4-L5 segment was significantly more common in the high PT group (odds ratio=4.65; 95% CI, 1.406-15.381; p=0.012). CONCLUSIONS: Patients with high pelvic tilt had a higher grade of lumbar disc degeneration in the L4-L5 segment regardless of age or gender.

STUDY DESIGN: Retrospective evaluation. OBJECTIVES: To determine the relationship between lumbar disc degeneration and back muscle degeneration. SUMMARY OF LITERATURE REVIEW: In the degenerative cascade of the spine described by Kirkaldy-Willis, degeneration of the disc and of the facet joint co-occur with aging. However, the muscles of the back are not included in this model. Several studies have reported significant correlations between back muscle degeneration and facet joint arthritis. The purpose of our study was to evaluate relationships between lumbar disc degeneration and fatty degeneration of the back muscles. MATERIALS AND METHODS: In this study, 65 patients over the age of 50 years who had undergone lumbar spine MRI in our orthopaedic clinic were recruited. Fatty degeneration of the back muscles was qualitatively graded from I to III by the degree of the fat signal in the muscle layer, including both the multifidus and erector spinae. Lumbar disc degeneration was graded from I to V according to the Pfirrmann grade. Correlations between the back muscle degeneration grade and radiological parameters were analyzed. RESULTS: The degeneration grade of the multifidus correlated positively with age and the grade of disc degeneration. Correlations with other radiologic parameters were not significant. The degeneration grade of the erector spinae correlated positively with age. Other radiologic parameters were not significant. CONCLUSIONS: There was a significant correlation between lumbar disc degeneration and multifidus degeneration. Erector spinae degeneration was correlated with age, but not with lumbar disc degeneration. The degenerative cascade of the spine was accompanied by fatty changes of the multifidus with aging.
