Subscapularis Z-plasty With Coracoidectomy for Internal Rotation Contracture in Children With Brachial Plexus Birth Injury.

OBJECTIVES: Brachial plexus birth injury (BPBI) is a rare dystocia complication. Although it has a good prognosis, a significant number retain functional impairment to varying degrees. The data concerning shoulder function improvement and complication rates are conflicting due to variations in outcome measures between the studies. Therefore, we report our experience with this approach. METHODS: It was a retrospective study conducted at King Faisal Specialist Hospital and Research Center in Riyadh (FSH&RC), Saudi Arabia. Data such as patient demographics, Mallet scores, and passive external rotation (PER) in adduction and abduction were retrieved from the medical records. RESULTS: In active shoulder function, Mallet score significantly improved (P=0.00). The improvement was most remarkable in active external rotation movement (P=0.00) followed by hand to the neck. However, no significant gain was observed in active abduction and hand-to-back. At the final follow-up, with a mean of 2.9 years, the improvement in PER in adduction and abduction was maintained. Compared to six months postoperative, no significant difference was found in hand-to-neck, hand-to-back, and total Mallet score. CONCLUSION: Subscapularis z-lengthening with coracoidectomy was consistently effective in correcting internal rotation contraction in a patient with BPBI. Significant improvements were observed in the Mallet score and PER in adduction and abduction.

Total Knee Arthroplasty With Megaprosthesis for Idiopathic Charcot Knee.

Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee. The diagnosis was established on the basis of history of neuropathic arthropathy of the knee, supported by knee radiographs and the exclusion of all known etiologies of Charcot knee. Because of a highly destructed knee joint, the patient underwent a total knee arthroplasty using the Global Modular Replacement System proximal tibial prosthesis. The surgery was done without any major complications, resulting in symptomatic and functional improvements.

Bone infarct transformation into undifferentiated pleomorphic sarcoma in sickle cell disease: A case report.

INTRODUCTION: Avascular necrosis of the bone is a very common finding in sickle cell disease (SCD). The malignant transformation of a pre-existing bone infarct is extremely rare, only few cases has been reported related to different etiologies one of which is SCD. PRESENTATION OF CASE: 40 years old male, known to have SCD, he presented as a case of avascular necrosis of the left proximal femur. Upon further investigations the lesion has transformed into undifferentiated pleomorphic sarcoma also known as Malignant Fibrous Histiocytoma (MFH). DISCUSSION: The exact mechanism of the malignant transformation of bone infarcts is not fully understood and yet to be investigated. Few cases were reported in literature of similar malignant transformation of a pre-exciting bone infarct and only one was linked to SCD. CONCLUSION: In reporting this case we hope that further cases worldwide will be reported. A high index of suspicion should be present when encountering bone infarct lesion with an unusual course.
