Total Elbow Replacements are indicated for pain and disability in patients with rheumatoid and osteoarthritis of the elbow. The quality of the cementation has been specifically studied and shown to be directly related to the clinical outcome and implant survival.

Aim

The aim of our study is to radiologically assess and grade the cementation around the components following total elbow replacement (GSB 3 or Coonrad Morrey) in two groups of patients.

Materials and methods

Group I underwent total elbow replacement using Heraeus cement gun with medium palacos viscosity cement and group 2 using Zimmer cement gun with simplex medium viscosity cement. Average age in Group 1 was 72.3 (range 67–88 yrs) and group 2 was 69 years (range 52–87 yrs)

3 Coonrad Morrey and 13 GSB 3 total elbow replacement were used in Group 1 and 2 Coonrad Morrey and 14 GSB 3 in group 2. The primary indication for surgery was osteoarthritis, rheumatoid arthritis, post traumatic arthritis and seronegative arthritis in both groups. The cementation was assessed radiologically using three grading system (Morrey, Gerber & Bristol).

Aim

The present study aimed to assess the accuracy of preoperative departmental ultrasound scans in identifying rotator cuff tears at our institution.

Methods

Preoperative ultrasound scan reports were obtained from 64 consecutive patients who subsequently underwent arthroscopic subacromial decompression and/or rotator cuff repair. Data was collected retrospectively using our 2010 database. The ultrasound reports were compared with the arthroscopic findings. The presence or absence of partial and full thickness rotator cuff tears was recorded.

Scaphoid injuries remain a challenge in both diagnosis and subsequent management. Untreated scaphoid non-union leads to inevitable osteoarthritis. Non-unions are picked up via an established management pathway in out trust and treated surgically with a standardised technique of non-vascularised bone grafting and retrograde screw fixation. Patients that underwent primary screw fixation and grafting for scaphoid non-union between 2004-2008 were reviewed. These patients were followed up clinically and radiologically. They were assessed for time to union, complications, DASH score, patient satisfaction and return to work. In addition comparison was made between the use of Herbert screw and Twinfix screw fixation and between tricortical iliac crest graft and corticocancellous distal radial bone graft. Forty-two consecutive patients underwent surgery of which 35 (83%) were available for follow up. Mean follow up was 39 months (range 13-72). 31 (89%) patients had gone on to radiological union. Of those united the mean DASH score was 11. Mean time to union was 4.4 months (range 2-15 95% CI 3.3 – 5.5). 95% of patients were satisfied with their operation and would recommend it to a friend in the same situation. No significant difference in outcomes were identified between Herbert screw and Twinfix screw fixation or between iliac crest or distal radial bone grafting techniques. This study has shown encouraging results for an established protocol for management of scaphoid non-union. Outcomes are as a good as any published comparable series in the literature and provide further support to the use of this technique.

The aim of the current study was to assess the amount of the distal humerus articular surface exposed through the Newcastle approach, a posterior triceps preserving exposure of the elbow joint.

24 cadaveric elbows (12 pairs) were randomized to receive one of the four posterior surgical approaches: triceps reflecting, triceps splitting, olecranon osteotomy and Newcastle approach. The ratio of the articular surface exposed for each elbow was calculated and compared.

The highest ratio observed was for Newcastle approach (0.75 ± 0.12) followed by olecranon osteotomy (0.51 ± 0.1), triceps reflecting (0.37 ± 0.08) and triceps splitting (0.35 ± 0.07). The differences between Newcastle approach and other approaches were statistically significant (p=0.003 vs osteotomy and < 0.0001 vs triceps reflecting and splitting).

The Newcastle approach sufficiently exposes the distal humerus for arthroplasty or fracture fixation purposes. Its use is supported by the current study.

Cement pressurisation in the distal humerus is technically difficult due to the anatomy of the humeral intramedullary (IM) cavity. Conventional cement restrictors often migrate proximally, reducing the effect of pressurisation during arthroplasty. Theoretically with a better cement bone interdigitation, the longevity of the elbow replacement can be improved.

The aim of this cadaveric study was to evaluate the usefulness of a novel technique for cementation.

Eight paired cadaveric elbows were used. The sides were randomly allocated to the conventional cementation group and pressurisation using a foley cathetre used as a cement restrictor. The cathetre was inserted into the IM canal after thorough washout and drying the cavity. The balloon inflated to act as a cement restrictor. Cementation was then performed and the cathetre removed just prior to cement setting. Radiographs of each pair was taken. Each distal humerus sample was cut in 1 cm increments starting from proximal part of the coronoid fossa. The slices were also radiographed to assess cement-bone interdigitation. The area of IM canal and the cement were calculated. The paired samples were compared.

The new technique consistently and significantly achieved a better cement interdigitation into the cancellous bone. The maximum penetration was observed in the proximal 1–3 cms from the coronoid fossa. According to previous studies, this area is the most common part involved in cement failure and loosening.

This study confirms the effectiveness of a foley cathetre as a cement restrictor. The ease of the technique and excellent pressurisation achived support its use.

The aim of this study was to determine patient-reported outcomes after arthroscopic rotator cuff repair with a new knot-free technique.

A questionnaire was completed by 50 patients who underwent an arthroscopic rotator cuff repair with a knot-free technique. Validated questionnaires included the Oxford Shoulder Score (12–60, good to poor) and SF-36 (0–100, poor to good). Patients also completed a 100mm VAS (0–100, good to poor) to rate the following domains: daytime pain, night-time pain, movement, strength, well-being, ability to do ADLs, participation in sports, ability to do leisure activities and whether they felt their shoulder was back to the way it was before the problem started.

The mean length of follow-up was 15 months (range 7–25 months). The mean age of patients was 62 years (range 36–78) and 70% were male. The mean OSS was 22 (SD 10). Mean scores for the 8 domains of the SF-36 were: 74 for physical functioning, 71 for role physical, 66 for bodily pain, 67 for general health, 57 for vitality, 82 for social functioning, 85 for role emotional and 81 for mental health. The mean VAS for the 9 outcome domains were as follows: 16 for night-time pain and daytime pain, 19 for movement, 21 for ability to do ADLs, 22 for well-being, 23 for whether the shoulder was back to the way it was, 28 for ability to do leisure activities, 29 for strength and 33 for ability to participate in sports.

In conclusion, patients reported excellent post-operative OSS with the knot-free technique. The SF-36 revealed that patients had high social and emotional functioning and good physical outcomes were reported on the VAS for pain, ADLs and movement. However, going back to an expected level of sport is not always achievable.

To assess the outcome of semi-constrained total elbow arthroplasty (TEA) in osteoarthritis and compare it to the rheumatoid group.

Two groups of patients assessed. In group-one with the diagnosis of rheumatoid arthritis 40 replaced elbows in 31 patients (25 female and 1 male), with average age of 67 (49–82) were reviewed. Group-two consisted of 14 elbows in 14 patients (9 female and 5 male) with post-traumatic osteoarthritis. Average age in this group was 71 (54–84). Mayo elbow performance (MEPS) and Liverpool elbow scores (LES) were used as the outcome measure.

The average follow up for group-one was 53 (20–90) and group-two 60 months (21–103). According to the MEPS 87.1% of patients in group 1 and 63.6% in group 2 had excellent or good outcome (p=0.09). Only one patient from group one and none in group two had the joint revised. No difference was observed in MEPS of group-one (86 ± 17) and group-two (77 ± 24), (p=0.25). Also the LES in the two groups were not different (p=0.85).

The outcome of TEA is satisfactory in both groups. No statistically significant difference was noted in the two groups. The recommendation of TEA in patients with osteoarthritis is supported by this study.

The aim of this study was to review the outcome of semi-constrained total elbow arthroplasty (TEA) in osteoarthritis and compare it to the rheumatoid group. This was performed on a single-surgeon, single-prosthesis (GSB III) series of patients. Two groups of patients assessed. In the first group with the diagnosis of rheumatoid arthritis 40 replaced elbows in 31 patients (25 female and 1 male), with average age of 67 (range 49–82) were reviewed. The second group consisted of 14 elbows in 14 patients (9 female and 5 male) with post-traumatic osteoarthritis. Average age in this group was 71 (range 54–84). All patients were recalled for clinical review. Fresh radiographs obtained and compared to the immediate postoperative images. Mayo elbow performance (MEPS) and Liverpool elbow scores (LES) were used as the outcome measure. Kaplan-Meier survival analysis for the two groups was performed. The average follow up for the first group was 53 (range 20–90) and second group 60 months (range 21–103). According to the MEPS 87.1% of patients in group 1 and 63.6% in group 2 had excellent or good outcome. This different was not statistically significant (p=0.09). Only one patient from group one and none in group two had the joint revised. No significant difference was observed in MEPS of group one (86 ± 17) and group two (77 ± 24), (p=0.25). Also the LES in the two groups were not different (p=0.85) (group one 8 ± 1 vs. group two 8 ± 2). The outcome of TEA is satisfactory in both groups. No statistically significant difference was noted in the two groups. The recommendation of TEA in patients with osteoarthritis is supported by this study.

Aims: To review the results from a series of GSB III total elbow arthroplasties performed at an independent centre. Between 1996 and 2004 the senior author performed 58 total elbow arthroplasties in 44 patients (10 males, 34 females) using the GSB III implant. These were reviewed and the outcome assessed through the use of a patient-answered questionnaire and clinical and radiological review. Mean age was 65 (49 to 84 years). Indications for surgery included rheumatoid arthritis (46 elbows) and post-traumatic osteoarthritis (11 elbows). Mean F/up was 4.1 years (0.8 to 8.5 years). 4 patients had died (6 elbows) and 4 patients (4 elbows) were unavailable for review. 2 of the implants had been revised (1x aseptic loosening, 1x deep infection), leaving a total of 46 elbows available for review. The survival rate at a mean of 4 years was 98% with aseptic loosening as the endpoint. Complications included 1 case of intraoperative fracture and 1 persistent ulnar neuritis. Overall patient satisfaction was high. The mean Mayo Elbow Performance Score was 83 out of 100 (range, 34 to 100) and mean Liverpool Elbow Score was 8 out of 10 (range, 1 to 10).

Conclusion: Previous studies of outcome following total elbow arthroplasty using the GSB III elbow prosthesis at independent centres have shown satisfactory results, but have looked at small groups of patients. Our results offer more robust data to show that the medium term outcome following total elbow arthroplasty using the GSB III prosthesis is satisfactory.

Background: Posterior dislocation of the elbow with fractures of the radial head and coronoid process is a rare injury which, when treated conservatively, has a high redislocation rate and poor results (7/11 in the largest published series). Methods: Six patients with this injury were treated with triple reconstruction, involving exploration of the joint via a lateral approach with insertion of a radial head prosthesis. The coronoid fracture and anterior capsule was repaired (using an in-to-out technique) and the lateral collateral ligament was reat-tached, using Mitek Super Anchors. All patients were evaluated prospectively. Results: The average age was 52 years (37–75y). At one year follow up all elbows remained in joint and all were pain free or causing slight pain only. The average range of ulno-humeral movement was 55 degrees (range 38–68) and the average forearm rotation was 67 degrees (range 18–104). Functional assessment showed an average Liverpool score of 23/36 (range 17–29) and average Broberg and Morrey score of 74/100 (range 68–84). Conclusions: Triple reconstruction recognises and remedies the three elements of this devastating injury. All of these must be addressed in order to fulþll the short-term goal of restoring and maintaining stability. Our patients have a stable, pain free, though stiff, elbow in contrast to the poor results reported from previous conservative and operative treatments.
