We describe a case of rotational dislocation of the proximal interphalangeal joint of the ring finger. This injury was not initially appreciated and therefore closed reduction failed. The clinical findings included puckering of the skin on the dorsum of the joint and rotational incongruity on radiographs. At open reduction there was interposition of the lateral band. Identification of the pathology allows early successful treatment.

Aim: This prospective study was carried out to assess the outcome of manipulation of the shoulder as a treatment for adhesive capsulitis of the shoulder.

Method: 31 patients were followed prospectively for twelve months after shoulder manipulation for adhesive capsulitis. All patients underwent manipulation under general anaesthetic and scalene block followed by intra-artificial gleno-humeral injection of steroid and local anaesthetic. Postoperative physiotherapy was started on the day of surgery. Shoulder function was assessed with range of movement, Constant and Murley score and DASH score (Disability of the Arm, Shoulder and Hand by specialist upper limb physiotherapists, pre-operatively, and post – operatively at 6 weeks, 3, 6, and 12 months.

Results: The DASH score improved from a mean of 60.1 (range 27–98) pre-operatively to a mean of 24.1 (range 5–83) at final follow up. Constant scores improved from a mean of 34.4 (range 16–51) pre-operatively to 65.8 (range 35–88). The mean improvement in Constant scores was 31.5 points.

Pre-operative range of movement (expressed as a percentage of the total ROM of the unaffected side) was 51.5 % (range 23.8–67.2). The mean postoperative ROM was 85.4% (range 56.2 – 99.3). External rotation improved from 41.7% (range 23.5 – 81.5) of the unaffected side preoperatively to 77.7% (range 44.1 – 105.3) at final review. Abduction improved from 47.4 % (range 23.3 – 70.6) to 85.4% (range 49.7 – 100) and forward flexion improved from 59.1% (range 33.5 – 73.9) to 90o (range 64.3 – 100.6). No patients required further manipulation.

Conclusion: All outcome measure improved following treatment. These improvements were sustained at 12-month follow up. In particular, external rotation which was the most restricted movement pre-operatively was seen to improve and this improvement was maintained throughout follow-up. We conclude that manipulation of the shoulder under inter-scalene block and general anaesthetic for adhesive capsulitis results in a sustained improvement in function and movement.

Between 1992 and 1997, we undertook a prospective, targeted clinical and ultrasonographic hip screening programme to assess the relationship between ultrasonographic abnormalities of the hip and clinical limitation of hip abduction. A total of 5.9% (2 of 34) of neonatal dislocatable hips and 87.5% (7 of 8) of ‘late’ dislocated hips seen after the age of six months, presented with unilateral limitation of hip abduction. All major (Graf type III) and 44.5% of minor (Graf type II) dysplastic hips presented with this sign.

Statistically, bilateral limitation of hip abduction was not a useful clinical indicator of underlying hip abnormality because of its poor sensitivity, but unilateral limitation of abduction of the hip was a highly specific (90%) and reasonably sensitive sign (70%). It was more sensitive than the neonatal Ortolani manoeuvre, which has been considered to be the method of choice. It was, however, not sensitive enough to be of value as a routine screening test in developmental dysplasia of the hip.

We consider unilateral limitation of hip abduction to be an important clinical sign and its presence in an infant over the age of three to four months makes further investigation essential.

Between May 1992 and April 1997, there were 20 452 births in the Blackburn District. In the same period 1107 infants with hip ‘at-risk’ factors were screened prospectively by ultrasound. We recorded the presence of dislocation and dysplasia detected under the age of six months using Graf’s alpha angle. Early dislocation was present in 36 hips (34 dislocatable and 2 irreducible). Of the 36 unstable hips, 30 (83%) were referred as being Ortolani-positive or unstable; 25 (69%) of these had at least one of the risk factors. Only 11 (31%) were identified from the ‘at-risk’ screening programme alone (0.54 per 1000 live births). Eight cases of ‘late’ dislocation presented after the age of six months (0.39 per 1000 live births). The overall rate of dislocation was 2.2 per 1000 live births.

Only 31% of the dislocated hips belonged to a major ‘at-risk’ group. Statistical analysis confirmed that the risk factors had a relatively poor predictive value if used as a screening test for dislocation. In infants referred for doubtful clinical instability, one dislocation was detected for every 11 infants screened (95% confidence interval (CI) 8 to 17) whereas in infants referred because of the presence of any of the major ‘at-risk’ factors the rate was one in 75 (95% CI 42 to 149).

Routine ultrasound screening of the ‘at-risk’ groups on their own is of little value in significantly reducing the rate of ‘late’ dislocation in DDH, but screening clinically unstable hips alone or associated with ‘at-risk’ factors has a high rate of detection.
