A consecutive series of 372 patients who underwent surgery for disorders of the rotator cuff involving arthroscopic subacromial decompression and open or arthroscopic repairs of the cuff were prospectively investigated as to the comparability of subjective and objective assessment scores of shoulder function. Assessments were made before operation and at 3, 6, 12, 18 and 24 months after surgery using the Disabilities of the Arm, Shoulder, and Hand score, the Oxford shoulder score and the Constant-Murley score, which was used as a reference. All scores were standardised to a scale of 0 to 100 for comparison. Statistical analysis compared the post-operative course and the mean score for the subjective Disabilities to the Arm, Shoulder and Hand score and Oxford shoulder score, with the objective Constant score at each interval. A strong correlation was evident between both subjective scores and the Constant score. We concluded that both the subjective scores would be useful substitutes for the Constant score, obviating the need for a trained investigator and the specialist equipment required to perform the Constant score.

Introduction: Open Repair of the Achilles tendon is associated with problems of wound breakdown and infection. Percutaneous methods have been associated with sural nerve injury. The Achillon system avoids these problems. However no studies have assessed the strength of this repair and whether it allows early active rehabilitation.

Materials/Methods: Simulated Achilles tendon ruptures in sheep Achilles tendons were repaired using either the Achillon method or a two strand Kessler technique with a No.2 Ticron Suture. The tendon diameter was measured in all cases, and was matched for both groups (mean 9mm, range 8–10mm). Specimens were loaded to failure using an Instron tensile testing machine.

Results: Mean load to failure for the Achillon method was 153.13N ±59.64 (range 65–270), and the mean load to failure for the Kessler Repair was 123.13N ±24.19 (range 75–150). This difference was not statistically significant p=0.209. A Pearson’s correlation coefficient was carried out for each group to see if mean load to failure was related to tendon diameter. There were statistically significant higher mean loads to failure for wider tendon repaired by the Achillon method p=0.047, however this was not the case with Kessler repairs p=0.231.

Discussion: The Achillon repair had a similar load to failure as the 2 strand Kessler repair. These results support the use of early active rehabilitation following the Achillon repair and we could not demonstrate stretching at the repair site. As this method is minimally invasive and does not grasp the tendon it may also have less effect on disruption of tendon blood supply and allow faster healing.

Conclusion: The Achillon repair has comparable tensile strength to Kessler Repair, and is a biomechanically sound method of repair of the acutely rupture Achilles tendon in suitable Patients.

Isolated arthrodesis of the subtalar joint has the advantage that it preserves some motion at the midfoot. In cadaveric studies, movement at the Talonavicular joint is reduced by up to 74% and at the Calcaneocuboid joint by up to 44%. This allows some midfoot flexibility, which would not occur with a triple arthrodesis.

There are several methods of performing a subtalar arthrodesis, broadly divided into extra or intra articular techniques, using structural or cancellous bone graft and a variety of fixation methods.

Earlier studies on primary arthrodesis have shown rate of non union from 0 – 6%. More recently, larger studies have reported higher rates of non union from 14 – 17%.

We present the results of 95 subtalar fusions performed with a standard technique, using one screw from the calcaneum to the talar dome, with 100% follow up.

Between 1993 and 2003 the senior author performed 105 subtalar arthrodeses. We performed a retrospective chart review. All patients with a primary subtalar fusion were included. All cases had been refractory to conservative therapy.

The senior author reviewed all patients until fusion had occurred or a diagnosis of nonunion was established. Fusion was diagnosed when the patient were pain free while fully weight bearing, with a clinically rigid subtalar joint and radiographs showing trabeculae crossing the arthrodesis. A CT scan was performed in all cases where nonunion was suspected, and the patient complained of persistent pain.

A total of ninety five subtalar arthrodeses were performed in ninety two patients. All were reviewed with clinical and radiological examination, until union had occurred or nonunion diagnosed. The average time to union was 5.0 months, range 3 – 12 months. The outcomes, graded using the method of Angus and Cowell, were 21 Fair, 7 Poor and 67 Good results
