OBJECTIVETo study the pathogenesis and treatment of gluteal heterotopic ossification caused by injection.

METHODSFrom April 2006 to May 2011, 4 old female patients with gluteal heterotopic ossification caused by injection were treated by resection. The average age was 71 years old ranging from 67 to 76. The illness were bilateral,the clinical character was pain and hard nodules in the both hip. The X-ray, CT and pathology matched the diagnosis of heterotopic ossification. Two of them were treated by totally removing the ossified tissues, and loosing the spastic and adhesive soft tissues. The other two were treated with local resection and soft-tissue lysis.

RESULTSThe wound of all patients healed well, and there were no complication. All patients were followed-up from 2 to 64 months(averaged 26 months). There were no lump and pain in the location of surgical resection.

CONCLUSIONGluteal heterotopic ossification caused by injection is the drug reaction produced by injecting benzyl alcohol or other drugs,and happens in adults. The key for the treatment is to remove part or all of the painful lump,and loose the local fascia and other soft tissues of the gluteal muscles.

OBJECTIVETo assess the different causes of thoracic ossification of the ligamentum flavum (TOLF).

METHODSFrom July 1989 to November 2005, 142 cases were diagnosed the TOLF, in which 121 were operated. The lesions were classified into three types on the basis of the clinical result: (1) In such primary group (Group 1, 90 cases), without incorporation disease and Ca, P and AKP was all normal; (2) In systemic ossified TOLF group (Group 2, 30 cases), 6 cases ankylosing spondylitis, 3 cases DISH, 10 cases fluorosis, 11 cases OPLL; (3) In local spine disease group (Group 3, 22 cases), 5 cases fracture in spine, 4 cases spine TB, 13 cases posterior marginal intraosseous cartilaginous node. Such clinical feature was analysed, moreover surveyed the thoracic kyphosis angle, upper thoracic kyphosis angle, lower thoracic kyphosis angle and the vertebra body wedge change. The effect was assessed using Epstein Scale.

RESULTS(1) In Group 1, the mainly type was connected type (67/90, 74%). The ossified ligamentum flavum was mainly located at the lower thoracic and thoracic-lumber levels. The local type was less. In Group 2, the mainly type was connected type (21/30, 70%). The local type was none. The lesions figure was the most. In Group 3, the local type was the most (18/22, 82%). (2) In Group 1, the ossified ligamentum flavum was mainly located at the upper and lower thoracic levels (225/486, 47%). In Group 2, mainly located at the whole thoracic, some include cervix and lumber. In Group 3, mainly location was related with the location of primary disease. (3) In group 1, the curve was normal in 81% (73/90) of cases. In Group 2, the curve was abnormal in 87% (26/30) of cases. In Group 3, the curve was normal in the 82% (18/22) of cases.

CONCLUSIONSThe TOLF relates with systemic ossify disease, the change of load on the spine, aging and so on. It should be classified according to its causes.

OBJECTIVETo investigate the surgical treatment of thoracic ossification of the ligamentum flavum (TOLF) and analysis of the therapeutic effects.

METHODSSix patients with thoracic ossification of the ligamentum flavum were retrospectively studied from October 2006 to October 2009. All of the patients in this group were treated by en bloc hemi-articular process laminectomy. There were 4 males and 2 females, ranging in age from 45 to 66 years, averaged 55.2 years. The evaluate factors including the preoperative and postoperative JOA scores,and the function of the urinary bladder were analyzed.

RESULTSAll the 6 patients were followed after operation. The mean followed-up duration was 10.5 months, ranging from 2 to 18 months. According to JOA evaluation criteria, 4 patients got an excellent result, 1 good and 1 bad. The one patient with bad result had spinal cord compressed for too long time, and the T2-weight MRI showed nonreversible degeneration of spinal cord and combined with schizophrenia. The clinical symptoms improved with varying degrees.

CONCLUSIONThe en bloc hemi-articular process laminectomy is an effective method for ossification of the thoracic ligamentum flavum. A thorough decompression and real-time protection of the spinal cord is the key to the success of surgery.

A lipogranuloma is an inflammatory reactive process associated with exogenous or endogenous lipids, and it's occurrence in the breast has rarely been reported. Osseous metaplasia, which is used to describe bone formation in abnormal locations, can develop from several conditions such as trauma or a tumor. However, few studies have reported benign breast lesions that have been seen as osseous metaplasia. We present a case of a benign calcified breast lesion that developed after a traumatic treatment process called "Bu-Hwang", and it was confirmed as a lipogranuloma with osseous metaplasia. To the best of our knowledge, this is the first reported case of a lipogranuloma with osseous metaplasia in the breast.

Heterotopic calcification following head and neck irradiation has rarely been reported. It usually develops as a late complication of radiotherapy in patients with malignancies, including breast cancer, lymphoma, and genitourinary malignancies. The occurrence of heterotopic calcification in the prevertebral space of the cervical spine has not been described as a late complication of irradiation. Here, we report a case of prevertebral heterotopic calcification in a patient with history of chemotherapy and radiotherapy for tonsil cancer 21 years ago.

INTRODUCTIONThis article aims to provide an overview of the epidemiology, medical and rehabilitation issues, current evidence for traumatic brain injury (TBI) rehabilitation, recent advances and emerging practices. Special TBI population groups will also be addressed.

MATERIALS AND METHODSWe included publications indexed in Medline and the Cochrane Database of Systemic Reviews from 1974 to 2006, relevant chapters in major rehabilitation texts and Physical Medicine and Rehabilitation Clinics of North America and accessed Internet publications.

RESULTSTBI has been implicated by the World Health Organisation to be a 21st century epidemic similar to malaria and HIV/AIDS, not restricted to the developed world. One third of patients may suffer severe TBI with long-term cognitive and behavioural disabilities. Injuries to the brain do not only damage the cerebrum but may give rise to a multisystem disorder due to associated injuries in 20% of cases, which can include complex neurological impairments, neuroendocrine and neuromedical complications. There is promising evidence of improved outcome and functional benefits with early induction into a transdisciplinary brain injury rehabilitation programme. However, TBI research is fraught with difficulties because of an intrinsically heterogeneous population due to age, injury severity and type, functional outcome measures and small samples. Recent advances in TBI rehabilitation include task-specific training of cognitive deficits, computer-aided cognitive remediation and visual-spatial and visual scanning techniques and body weight-supported treadmill training for motor deficits. In addition, special rehabilitation issues for mild TBI, TBI-related vegetative states, elderly and young TBI, ethical issues and local data will also be discussed.
