Aims

The aim of this study was to investigate the clinical and radiographic outcomes of microendoscopic laminotomy in patients with lumbar stenosis and concurrent degenerative spondylolisthesis (DS), and to determine the effect of this procedure on spinal stability.

Patients and Methods

A total of 304 consecutive patients with single-level lumbar DS with concomitant stenosis underwent microendoscopic laminotomy without fusion between January 2004 and December 2010. Patients were divided into two groups, those with and without advanced DS based on the degree of spondylolisthesis and dynamic instability. A total of 242 patients met the inclusion criteria. There were 101 men and 141 women. Their mean age was 68.1 years (46 to 85). Outcome was assessed using the Japanese Orthopaedic Association and Roland Morris Disability Questionnaire scores, a visual analogue score for pain and the Short Form Health-36 score. The radiographic outcome was assessed by measuring the slip and the disc height. The clinical and radiographic parameters were evaluated at a mean follow-up of 4.6 years (3 to 7.5).

We classified fractures of the base of the middle phalanx into five types: 1) single palmar fragment; 2) single dorsal fragment; 3) two main fragments; 4) not involving the articular surface, including epiphyseal separation in children; and 5) all others. Types 1 and 2 were subclassified into avulsion, split and split-depression.

Surgery is recommended for unstable type-1 avulsion fractures, type-2 avulsions which may develop buttonhole deformities, and all fractures which displace articular cartilage surfaces. Long-term follow-up showed that surgical treatment which produced good stability and congruity gave good results. These should be the primary aims of treatment.

We treated 31 patients with non-traumatic paralysis of the posterior interosseous nerve over 15 years. There were 10 men and 21 women of mean age 40.3 years (17 to 71). Six were managed conservatively, and 25 by operation.

In 14 patients entrapment occurred at the supinator, including three who had double compression at both the entrance and exit from the muscle. In four it was caused by a ganglion, in one by a lipoma, in one by a dislocated radial head and in two by a marked constriction in the nerve of unknown cause. The remaining three patients were retrospectively diagnosed as having neuralgic amyotrophy, the only observable change at operation being slight oedema of the nerve.

Paralysis recovered in 24 out of the 25 patients at between 2 to 18 months (mean 5.6) after operation, and the one failure was treated later by tendon transfer.

We reviewed 166 adult patients on long-term haemodialysis, dividing them into three groups according to the presence and type of shoulder pain. The 24 patients in group A, with spontaneous pain related to a supine posture, had been under haemodialysis for significantly longer than the others, and had a much higher incidence of carpal tunnel syndrome.

Open or arthroscopic resection of the coracoacromial ligament in 21 shoulders relieved pain during haemodialysis and night pain, and histological examination showed amyloid deposits and inflammatory-cell infiltration in the subacromial bursa in almost all cases, and in the tenosynovium of the bicipital groove in some.

We conclude that one type of shoulder pain experienced by patients on long-term haemodialysis is caused by the subacromial impingement of amyloid deposits. This should be distinguished from other types of shoulder pain, because it can be relieved by resection of the coracoacromial ligament.
