Calcified thoracic intervertebral disc at two levels as a cause of mid-back pain in a child: a case report.

An uncommon case of calcified disc at two levels in the thoracic spine is presented. A 12-year-old girl presented with intervertebral thoracic disc calcification from the levels D7-D8 and D11-D12. Level D7-D8 remained asymptomatic, whereas at level D11-D12 she had spontaneous pain for 10 months. Her symptoms were self-limiting and disappeared with bed rest, analgesics, and the use of a brace. The radiological changes were the same at 4-year follow-up, but the patient remained asymptomatic.

Hemiplegic/monoplegic presentation of cervical spine (C1-C2) tuberculosis.

Tuberculosis of the craniovertebral region is very rare. Neural deficit in this region is reported in between 24% and 64% of cases, and mainly takes the form of quadriparesis. Hemiplegic and monoplegic presentation among this set of patients is rarer. Out of 32 patients treated at our institution between May 1989 and February 2001, only one had hemiplegia, while two had monoplegia. These three cases are discussed. Case 1 involved a 45-year-old woman who presented with hemiplegia following a trivial fall. Plain radiographs and computed tomographic (CT) scans of the skull appeared normal, but CT scans of C1-C2 and the craniovertebral junction revealed destruction of the dens and atlantoaxial subluxation. The patients in cases 2 and 3 had monoplegia. Plain radiographs in both cases showed an increased prevertebral soft tissue shadow in front of C1-C2. CT in case 2 and magnetic resonance imaging (MRI) in case 3 revealed destruction of the arch of C1 and the dens, with subluxation. All three patients were successfully treated with rest, skull traction, anti-tubercular drugs and suitable braces. Case 3 required stabilization. All three patients achieved complete neural recovery. Patients 1, 2 and 3 had 22, 48 and 4 months' follow-up respectively. Patient 3 was subsequently transferred to a neurosurgery ward for stabilization of the occipito-C3 vertebrae. Hemi/monoplegic presentation is extremely rare; no author in the literature is able to give reason for the rarity or the pathomechanics of the condition. We believe that if medullary cervical junctional involvement extends slightly higher (in rare circumstances), with involvement of one of the branches of the vertebral or lower basilar artery, medial medullary syndrome will occur, sparing medial lemniscus and emerging hypoglossal nerve fibres. Thus the pyramids will be involved, causing contralateral hemiparesis, and if the pyramids are selectively involved, it will cause contralateral monoparesis.

Isolated dislocation of the second metacarpal at both ends.

A dislocation of the second metacarpal at both ends is reported herein for the first time. Six weeks after injuring her right hand in a fall while climbing stairs, a 34-year-old woman visited our clinic with pain, swelling, and deformity of her hand. The radiographs showed a volar dislocation of the head and a dorsal dislocation of the base of the second metacarpal. The probable mechanism of injury was the hyperextension at the metacarpophalangeal joint; this force dislocated the metacarpal head toward the volar plate. Force then further continued along the second metacarpal shaft in the hyperflexed wrist, thus dislocating the base dorsally. We performed an open reduction and K-wire fixation of the second metacarpophalangeal joint and an arthrodesis of the second carpometacarpal joint. At the six-month follow-up, the patient had restricted flexion (0 to 50 degrees) at the second metacarpophalangeal joint, but full range of motion at the interphalangeal joints. The grip strength on the right side was 70% of that measured in the uninvolved hand. Key Words: Dislocation, Second metacarpal.

Cubitus varus: problem and solution.

A lateral closing wedge osteotomy was performed in 39 children with cubitus varus deformity resulting from a supracondylar fracture. All had a deformity of 15 degrees or more, with 5 having more than 30 degrees of varus. The osteotomy was fixed by three different methods. In 8 cases the osteotomy was fixed with 2 parallel Kirschner wies (group K). A modified French technique (group TBW) was used in 25 cases and held with a figure-of-8 wire loop tightened over the screw heads. In the last 6 cases the osteotomy was fixed with an external fixator (group EF). The only poor result (i.e. loss of carrying angle of more than 10 degrees and loss of flexion and extension of 20 degrees or more) was in group K due to pin tract infection and loosening of the K-wires. In the TBW group 5 patients lost some degree of correction, and none became infected. In the EF group no patient suffered pin tract infection or loss of correction. Based on our experience and results, we feel that the best age at which to correct cubitus varus deformity was 6-11 years and that the external fixator is a safe, effective and reliable method to fix the osteotomy. We propose this method of fixation as a good alternative method to the modified French technique, especially in cases of severe cubitus varus deformity, where removal of a large wedge can produce a big step at the osteotomy site, increasing the possibility of disengagement of the stainless steel wire from the screw head. In addition, minor postoperative modifications of correction, if required, can also be performed. It also avoids a second operation for implant removal.

Correlation of clinical course with magnetic resonance imaging in tuberculous myelopathy.

Sixty cases of spinal tuberculosis with neurological deficit treated with 'middle path regimen' were analysed and therapeutic response was correlated with the magnetic resonance imaging (MRI) observations. Tuberculous lesions were found to be more extensive than seen on plain X-ray in 60% of the cases. MRI showed the involvement of one or both pedicles in nearly 90% of the cases, in addition to the vertebral body lesion as seen in the X-rays. The patients showing predominantly extradural collection of fluid with relatively preserved cord size, and MRI evidence of myelitis/oedema, improved neurologically with treatment. The myelomalacia of cord was found to be a poor prognostic sign for neural recovery. The magnitude of thinning of cord did not always correlate with severity of neural deficit, however, thinning of cord in association with myelomalacia carried a bad prognosis. The complete neural recovery is not expected in patients with syrinx formation proximal or distal to the diseased spine, either with antitubercular drugs or after mechanical decompression. MRI changes in dura-subarachnoid complex suggesting arachnoiditis generally correlated with poor neural recovery. MRI provided a reliable guide to the level and extent of surgical decompression, and prognostication of the outcome of therapeutic measures.

Evaluation of foot bimalleolar angle in the management of congenital talipes equinovarus.

The study was undertaken to establish the normal foot bimalleolar (FBM) angle in Indian infants and to correlate it with the severity of deformity and results of treatment in congenital talipes equinovarus (CTEV). Foot tracings with the level of both the malleoli of 182 feet (91 normal Indian infants) were taken. The anteromedial angle between the long axis of foot and the bimalleolar plane was taken as the FBM angle. The FBM angle in normal infants was calculated as 82.5 degrees. Eighty-four CTEV (51 patients) were clinically classified as grade I (five feet; FBM angle, 73.2 degrees), grade II (21 feet; FBM angle, 66.6 degrees), and grade III (58 feet; FBM angle, 54.7 degrees), depending on whether the foot could be passively corrected (grade I) or had a fixed equinus and/or varus of <20 degrees (grade II) or >20 degrees (grade III). Thirty-one feet (22 patients) were followed up prospectively after conservative (17 feet: grade I, three feet; grade II, three feet; grade III, 11 feet) and surgical release (all grade III, 14 feet). All feet with grade I and grade II deformity and 44% (11 feet) with grade III deformity were amenable to gentle graduated manipulations and cast application, whereas 56% (14 feet) with grade III deformity underwent soft tissue release. After nonsurgical treatment, the mean FBM angle was 82.3 degrees. Of the feet that underwent surgery, those with excellent (11 feet) and good correction (3 feet) had a mean FBM angle of 79.9 degrees and 74.3 degrees, respectively. There were no feet with fair or poor results. The clinical severity of foot deformity and results of treatment correlated well with the FBM angle. Foot tracing with the FBM angle is a simple, objective, and reproducible clinical criterion to classify the severity of foot deformity and evaluate the results of treatment.
