Great care should be taken to minimise damage to the pharynx and upper oesophagus during an anterior approach to the cervical spine. If noticed at the time of surgery primary repair should be carried out; if noticed in the postoperative period, thorough cleaning and placement of a pharyngocutaneous drain will result in spontaneous healing of the majority of fistula. For persistent fistula secondary repair is required using well-vascularised tissue.

We describe cases presenting with progressive thoracic myelopathy after lumbopelvic fusion attributed to proximal junctional vertebral compression fracture (PJF) followed by spinal calcium pyrophosphate dehydrate (CPPD) crystal deposition. ⋯ The combination of mechanical stress plus PJF and CPPD crystal deposition followed by a foreign body reaction to the deposited crystals caused myelopathy. Patients with radiographic evidence of PJF, especially UIV collapse, after lumbopelvic fusion should be followed carefully for the emergence of myelopathy.

Comparative Study
Comparative analysis of complications of different reconstructive techniques following anterior decompression for multilevel cervical spondylotic myelopathy.
Anterior approach was extensively used in surgical treatment of multilevel cervical spondylotic myelopathy. Following anterior decompression, many different reconstructive techniques (multilevel ACDF, hybrid construct and long corpectomy) all had satisfied outcomes. However, there are few studies focusing on the comparison of these three reconstructed techniques. The aim of this retrospective study was to analyze the complications of these three different methods. ⋯ Most of the complications of the three reconstructive techniques subsided gradually after conservative treatment; none of them needed revision surgery. The multilevel ACDF approach has the lowest rate of non-union, but a slightly higher morbidity of the laryngeal nerve-related complication if proximal segments were involved. The long corpectomy approach should be selected prudently because of the high rate of complication.
