Ischial Tuberosity Avulsion Stress Fracture after Short Period of Repetitive Training.

Fatigue fracture of the pelvis is the form of fracture due to repetitive micro-stress accumulation, can be affected by a number of factors such as patient's nutritional status, biomechanics, social status and so on. Still there is no study about precise standard degree of external force that lead to stress fracture, but it may caused by compression force, traction force or complex force and others. Avulsion stress to ischial tuberosity or anterior superior iliac spine by attached muscle is known as the main factor for the avulsion fracture.

Characterizing the Progression of Varying Types of Calcific Tendinitis around Hip.

Purpose: To assess the progression of clinical symptoms and disease course of calcific tendinitis in the hip region according to types of calcification.

Materials And Methods: Among patients with the hip pain, 28 patients (21 males and 7 females; mean age 51 years, range 32-74 years) showing calcified lesions in simple radiography without other possible sources of pain were analyzed retrospectively. Twelve patients displayed a symptom duration of less than three weeks (acute; average=1±0.

Bilateral Necrotizing Fasciitis around the Hips Differentiated from Fournier Gangrene: A Case Report.

As an emergency encountered in orthopedic practice requiring prompt diagnosis and aggressive treatment, necrotizing fasciitis around the hip must be discriminated from Fournier gangrene. The current case report describes a patient who suffered from bilateral type I necrotizing fasciitis around the hips, which was alleviated by prompt surgical debridement and intensive postoperative care.

Cross-cultural adaptation and validation of the Korean version of the Michigan hand questionnaire.

Purpose: The Michigan hand questionnaire (MHQ) is increasingly being used and has been adapted cross-culturally in some Western and Asian countries, but the validation process for an Asian translation of MHQ has not been well described. In this study, we translated and adapted the original MHQ cross-culturally to produce a Korean version, and then assessed the validity and reliability of the Korean version of the MHQ.

Methods: A total of 176 patients with common hand disorders completed the Korean version of the MHQ and the Disabilities of the Arm, Shoulder, and Hand questionnaire.

A case of fracture of posterior margin of lateral tibial plateau by pivot shift mechanism in chronic ACL insufficiency.

We present a case of the fracture of the posterior margin of the lateral tibial plateau, probably by pivot shift mechanism in a chronic anterior cruciate ligament (ACL) insufficient knee. Multitudes of direct and indirect signs of ACL injury were evident on MRI, including anterior translation of the lateral tibial plateau, buckling of the posterior cruciate ligament, deep sulcus sign, and the fracture of the posterior aspect of lateral tibial plateau. With careful interpretation of the history and arthroscopic findings, the main insult of the current case was identified as the fracture of the posterior margin of the lateral tibial plateau with antecedent chronic ACL insufficiency, rather than as the acute or subacute ACL rupture.

A case of pathologic fracture of femur whose primary tumor and occult metastases were ascertained by PET-CT.

We report a case of metastatic pathologic fracture of femoral shaft, whose primary cancer was ascertained by positron emission tomography-computed tomography (PET-CT). The abnormally increased biological activity of the space-occupying lesion of the lung was clearly demonstrated by PET-CT. Moreover, the occult bony metastatic lesions were confirmed with evidence of altered biologic activity.

Lateral epicondylar femoral avulsion fracture combined with tibial fracture: a counterpart to the arcuate sign.

We present a case of femoral avulsion of the lateral collateral ligament (LCL) with complete tear of the posterior cruciate ligament (PCL) and popliteus tendon accompanied by demonstrable posterolateral rotary instability (PLRI) of the knee. A 55-year-old man was involved in a road traffic accident. Radiographs revealed an avulsion fracture of the lateral epicondyle of the femur and a fracture of the tibial shaft.

Meniscal ossicle: a case report.

Meniscal ossicle is a cortical or cancellous tissue with central viable marrow surrounded by meniscal cartilage. We present a case of medial meniscal ossicle at its posterior horn. A 21-year-old male military recruit visited our clinic due to left knee discomfort.

Localized nodular synovitis of the knee presenting as anterior knee pain: a case report.

The localized nodular synovitis is a benign proliferative synovial tumor manifesting as an intra-articular solitary nodule. We report a case of localized nodular synovitis at the infrapatellar fat pad of the knee which presented as a vague symptom of anterior knee pain. An arthroscopic excision of the lesion relieved the anterior knee pain and there has been no evidence of recurrence.

An en bloc avulsion fracture of tibial tuberosity and Gerdy's tubercle in an adolescent basketball player: a case report.

We report a case of en bloc avulsion fracture of tibial tuberosity and Gerdy's tubercle, which has never been reported. A 14-year-old boy suffered from an acute pain in his left knee during running just before a jump. Simple radiographs showed an avulsion of the tibial tuberosity.
