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.

OBJECTIVESTo investigate the long-term surgical outcome of thoracic myelopathy caused by the ossification of the ligamentum flavum (OLF) and evaluate the related risk factors.

METHODSForty-four patients who underwent decompressive laminectomy with thoracic OLF between January 1990 and December 2005 and got more than 5 years follow-up were retrospectively reviewed. Among these 44 cases, there were 29 male and 15 female whose ages at operation were 52 years averagely (27-68 years). The 2-year follow-up results and long-term outcomes were classified according to the modified Epstein's standard, and then the rates of excellent or good (REG) were calculated. The correlation between the long-term REG and the patients' ages, durations of symptoms, decompressed levels, and dural leak were analyzed.

RESULTSThe mean follow-up period of these 44 cases was 8.5 years (5-19 years). The REG at 2 years after laminectomy was 77.3% (34/44), while the long-term REG was 65.9% (29/44). There was one case who had suffered from an acute spinal cord injury got a poor post-operative outcome. The other 43 cases had chronic durations, including 22 cases whose pre-operative durations of symptoms were less than 12 months and 21 cases whose durations were equal to or more than 12 months. And the long-term REG of these two groups were 77.3% (17/22) and 57.1% (12/21) respectively (P>0.05). The REG of those cases whose decompression levels were limited in T1-T9 was 78.9% (15/19), while that of those cases whose laminectomy was relevant to thoracolumbar segment (T10-L2) was 58.3% (14/24) (P>0.05). There were 7 cases who had excellent or good short-term results and poor long-term outcomes. The reasons of these changes included coexistence of lumbar spinal stenosis in three cases and the growth of the OLF at the adjacent levels in four cases.

CONCLUSIONSAlthough the short-term results of the decompressive surgery for thoracic OLF is good, the regular long-term follow-up is necessary because the symptoms may reoccur or deteriorate secondary to lumbar spinal stenosis or the growth of OLF at the adjacent levels near former decompressive levels; the duration of symptoms which is more than one year and the decompression levels that is involved to T10-L2 segments are possibly related to the poor long-term outcomes.

OBJECTIVETo evaluate the clinical effect of surgical resection of the severe heterotopic ossification (HO) after the open reduction internal fixation (ORIF) of acetabular fractures.

METHODSFive cases of severe HO after the ORIF of acetabular fractures were treated by surgical resection from October 2005 to April 2007. All patients were male, the average age was 34 years (22 to 45 years). The average time of HO after ORIF of acetabular fractures was 14.2 months (3 to 30 months). The original surgical approaches were: Kocher-Langenbeck approach as 4, ilioinguinal combined K-L approach as 1. According to the Brooker classification, there were 4 patients with IV degree and 1 with III degree. The average total movement for all the 5 patients was 8 degrees. All patients received one time radiation therapy before or after operation, the dosage was 7-8 Gy. The surgical approach was Kocher-Langenbeck for all patients. During operation the nerve stimulator was used to explore the sciatic nerve and carefully protected it, resected all HO bone and removed all implants. For one patient, because of confusion between femoral head and acetabulum, total hip replacement were performed. The joint exercise (passively and actively) began from the second day after operation, and at the same time, all patients took the indomethacin to prevent the occurrence of HO.

RESULTSAll patients were followed up for 4 to 22 months. There was no recurrence of HO, the average total movement for all the 5 patients was 160 degrees.

CONCLUSIONEarly surgical resection and combined with radiation and indomethacin for the severe HO after the ORIF of acetabular fractures can obtain excellent results.

Acute neurologic deterioration is not a rare event in the surgical decompression for thoracic spinal stenosis. We report a case of transient paraparesis after decompressive laminectomy in a 50-yr-old male patient with multi-level thoracic ossification of the ligamentum flavum and cervical ossification of the posterior longitudinal ligament. Decompressive laminectomy from T9 to T11 was performed without gross neurological improvement. Two weeks after the first operation, laminoplasty from C4 to C6 and additional decompressive laminectomies of T3, T4, T6, and T8 were performed. Paraparesis developed 3 hr after the second operation, which recovered spontaneously 5 hr thereafter. CT and MRI were immediately performed, but there were no corresponding lesions. Vascular compromise of the borderlines of the arterial supply by microthrombi might be responsible for the paraparesis.

OBJECTIVE: To investigate the application and the clinical effect of nasal endoscope in styloid process truncating operation. METHOD: Dividing 66 patients into nasal endoscope group and control group randomly, and then observe them. Nasal endoscope group were cured with nasal endoscope during the styloid process truncating operation and the control group were treated with the routine method of intraoral path. All the operations were executed by the same person. Observation index included the following aspects: the length of the truncated styloid process, the operation time, intraoperative bleeding, postoperative pain and pain degree, inflammatory reaction of raw surface and rehaemorrhagia. RESULT: Compared with the control group, the length of the truncated styloid process of nasal endoscope group were longer and the operation time had no significant differences. The intraoperative bleeding of intraoperative bleeding group were (85.0 +/- 35.0)ml and in control group were (95.0 +/- 40.0)ml. There are no significant differences between the result. Nasal endoscope group also had the advantages of fewer aches and less inflammatory reaction of raw surface. Both of the team had no rehaemorrhagia. CONCLUSION nasal endoscope can truncate a longer styloid process in styloid process truncating operation and is effective to relieve pain, and ease inflammatory reaction, it's a safe mini-trauma operation.
