Objective

The aim of this retrospective study is to assess the functional and radiological outcome of a multi-planar corrective osteotomy, distraction and locking fixed angle volar plate as the standard of treatment of distal radius mal-unions that require multi-planar correction.

Purpose of study

The aim of this study is to evaluate the role of low intensity pulsed ultrasound, Exogen in the treatment of delayed and non unions. Methodology: We conducted a retrospective study of 292 patients who has had Exogen treatment for delayed and non union from 2005 to 2009. Patient's age, sex, associated co morbidities, smoking history, medications, type of fractures (open/closed), infection and site of fractures were sought for. 271 patients' data (228 delayed and 43 non unions) were available during the study with mean age of 53.5 yrs.

Exogen therapy was initiated at 3–4 months for delayed unions and 6–12 months for non unions in 61 tibia (15 open); 31 femur (2 open); 20 scaphoid; 38 5th metatarsal; 31 ankle (2 open); 17 ulna (1 open); 15 radius (3 open); 29 humerus (2 open); 16 clavicles; 6 olecranon; 4 pilon (2 open) and 2 metacarpal fractures.

Between 1994 and 2002, 81 patients underwent ulnohumeral arthroplasty for elbow arthritis at our institution. All patients were sent a questionnaire with a request to attend for a clinical evaluation. Forty replied and 34 attended for clinical examination, 6 females and 34 males with an average age of 63 years (32-80) and a mean follow-up of 6 years (2-10). There were 22 (55%) patients with primary osteoarthritis, 14 (35%) with osteoarthritis secondary to trauma, two patients with rheumatoid arthritis and one patient each with arthrogryphosis multiplex congenital and post-septic arthritis of the elbow.

Using the VAS (0-10), the pain score was seen to improve from a mean pre-operative score of 8 (6-10) to 4 (0-9). 21 patients (50%) were on minimal or no analgesia and 31 (75%) patients felt they would have the surgery again for the same problem. The arc of motion as regards flexion/extension was found to increase by 19% while prono-supination was found to increase by 30%. There was one patient each with superficial infection, anterior interosseous nerve neuropathy and myositic ossificans while two patients had triceps rupture. Radiological examination showed that in 12 cases the trephine hole was partially obliterated while in 4 cases it was completely obliterated. This could not be correlated clinically. Patients with loose bodies seemed to do better in the post-operative phase.

Ulnohumeral arthroplasty has a role in the management of the arthritic elbow as it provides pain relief in the post-operative period; however, the improvement in the range of movement is limited particularly as regards the arc of extension.

Introduction: Distal radius locking plates are increasingly being used to treat distal radius fractures.

The purpose of our study was to determine the medium term clinical and radiological outcome of comminuted, displaced fractures of the distal radius. We present our experience in using the Aculoc (Acumed) volar fixed angle plate to treat 100 consecutive fractures of the distal radius.

Methods: All one hundred patients were prospectively (clinically and radiologically) assessed between 2003 –2007, with a minimum follow up of one year. Fractures were radiologically classified using the Frykman classification Clinical outcome was measured using the Mayo score, DASH questionnaire, SF36 and Range of Wrist Movement and pinch and grasp power. The post operative x rays were assessed for fracture union, alignment and displacement.

Conclusion: Our study demonstrates that volar fixation of distal radius fractures, using a fixed angle, locking accumed plate provides satisfactory treatment for fractures of the distal radius. Angular stability of the implant provides mechanical stability and aids early rehabilitation which results in good functional outcomes.

Full thickness skin grafting has been used following dermo-fasiectomy for Dupuytren’s contracture. We have used a conservative approach following excision of the contracture. Following radical excision through Brunner’s incision, an elliptical full thickness skin graft is harvested from the volar aspect of the wrist. This is applied to the wound on the volar aspect of the proximal phalanx to cover the gap with the finger held in extension. Patients who have undergone primary Dupuytren’s excision between 1990–1998 were recalled and evaluated in special clinic. Clinical notes were reviewed for pre-operative deformity, wound problems if any and recurrence of deformity at annual follow-up. Patients were reviewed for present status of deformity, ROM, sensation, 2-point discrimination, evidence of recurrence and patient satisfaction.

One hundred and six fingers were evaluated in 80 patients. Average duration of follow-up was 52 months. Sixty-five patients had bilateral disease and 29 patients had family history of Dupuytren’s disease. Average pre-operative flexion deformity of the PIP joint was 68.6 degrees and 12 patients had deformity of the DIP joint. Mean flexion deformity at review of the PIP joint was 26.4 degrees. 29 patients reported sensitivity to cold. Two-point discrimination was abnormal in 24 patients. Skin tightness was noted in 8 fingers and 7 cases had recurrence. In 2 fingers the recurrence was away from the graft and in remaining 5 fingers it was proximal to the graft not crossing the grafted area. Thirty-three patients had progressive disease in the adjacent fingers away from the operated area. There was no case of graft loss. Seventy patients were satisfied with the end results of the operation.

Our study has shown a very low incidence of recurrence following radical dissection and similar result as dermo-fasciectomy, and the skin graft acting as a barrier in cases of recurrence. Also graft harvested from the wrist matches the colour of the palm with increased patient satisfaction.

Aim: To evaluate the therapeutic effectiveness of steroid injection in AC joint arthritis. Method: We prospectively evaluated the outcome of 20 consecutive patients (25 shoulders) with clinical and radiological evidence of primary ACJ arthritis after steroid injections. All patients were evaluated using the Constant score after a minimum of 12 months follow up. Only patients with a negative provocative test after injection of 2ml of depomedrone and lignocaine were included in the study. Results: Eleven females (14 shoulders) and 9 males (11 shoulders) were included. The average age was 53.9 years (range 28 Ð79). The mean preinjection score was 61.6 points (SD 13.12). At 6 months this improved to 81 points, mean difference of 19.36 (CI = 14.19 Ð 24.53), p< 0.01, which was highly statistically signiþcant. There was further improvement at 12 months, on the 6 month score, mean 88.4 points, mean difference of 7.4 (CI = 3.55 Ð 11.25), p = 0.001 which was also statistically signiþcant. In addition, the younger the patient, the greater the improvement in the objective score which measures the range of movement and power (r = −0.47; p = 0.01). Conclusion: We conclude that local steroid injection is an effective method of treatment for primary isolated acromioclavicular arthritis and improvement continues for at least 12 months, but may require more than one injection.

Numerous procedures have been described for degenerative arthritis of the carpometacarpal joint of the thumb. The sling procedure is technically demanding and involves sacrificing part of a healthy tendon. Silicon arthroplasty is associated with stem fracture and synovitis. We have successfully used external fixation for distraction and correction of adduction deformity following trapeziectomy with S-Quattro (Stockport Serpentine Spring System). Following trapeziectomy specially designed pins are inserted into the base of the 1^st metacarpal and radial styloid and distracted with 2 serpentine springs. The fixator is removed at six weeks and removable thermoplastic splint applied for further 6 weeks.

We reviewed the results of 39 trapeziectomy performed in 32 patients (3 male) with an average follow up of 53 months. ROM, power, pinch, pain score and patient satisfaction were reviewed by an independent hand therapist.

Average functional score was 28. 9 post-op (maximum 30) compared to 20. 7 pre operatively. Mean thumb abduction was 48. 9 and extension 49. 2 degrees which increased from 42. 9 and 43. 8 pre-operatively. Span was 19 centimetres and opposition 9. 26 on the Kapandji scale. Average grip strength was 40 lbs, pinch strength of 6 lbs and key lateral of 9. 5 lbs. Pain score improved from 7. 9 pre-op to 0. 9. There was statistically significant improvement of all functions except span. Long term follow up radiograph showed good maintenance of gap between base of 1^st metacarpal and scaphoid. Three cases had deep penetration of the pins, which required early removal. We now insert padding between the fixator and the spring to avoid deep penetration. One patient had mild RSD and another patient had pain in the distribution of the radial nerve, both of which improved following pin removal.

Application of S-Quattro following trapeziectomy is a simple and quick procedure. It is reasonably well tolerated by patients. Long-term follow-up showed improvement in hand function and good maintenance of gap between base of 1^st metacarpal and scaphoid.

We present the mid term results of 267, 3M Capital hip replacement performed in a single institution from 1991 to 1994. Patients were recalled back to clinic in April 1998 after the reported high failure rate of 3M hips. Fifty- nine hips were excluded from this study for various reasons.

Average follow-up was 68.8 months. Nine (4.2%) have been revised for aseptic loosening at the time of review and further 10(4.8%) of the stems are radiologically loose. There was no statistical significant difference between hips that failed, regarding grade of the operating surgeon, surgical approach: trochanteric osteotomy or Hardinge, or type of prosthesis used: monoblock (stainless steel) or modular (titanium). Acetabular wear rate, width of medial cement mantle or cancellous bone at level of neck at Gruen zone7, or stems with canal fill index less than 50%, 7 cm below the level of the collar also showed no statistical difference. Male patients had higher incidence of loosening (p=0.001) which was statistically significant. Both varus and valgus alignment of the stem had higher failure rate which was significant. We could no find any obvious reason for failure in 10 of the 18 patients. The stem was either in varus or there was an inadequate cement mantle in 8 of the failed hips on the initial postoperative radiograph. A feature of this study was high incidence of endosteolysis and debonding of prosthesis from cement in the failed cases.

The present series showed considerably lower revision and loosening rate of 3M stems compared to the published series, the reason for which is not clear. Only Palacos cement was used in this series, which may partly account for the lower failure rate. Surface finish of the stem leading to debonding of the prosthesis from cement along with different modulus of elasticity probably accounts for the higher rate. Technical failure is partly to blame for the higher failure rate.
