To prevent insufficiency of the triceps after total elbow arthroplasty, we have, since 2008, used a triceps-sparing ulnar approach. This study evaluates the clinical results and post-operative alignment of the prosthesis using this approach.

We reviewed 25 elbows in 23 patients. There were five men and 18 women with a mean age of 69 years (54 to 83). There were 18 elbows with rheumatoid arthritis, six with a fracture or pseudoarthrosis and one elbow with osteoarthritis.

Post-operative complications included one intra-operative fracture, one elbow with heterotopic ossification, one transient ulnar nerve palsy, and one elbow with skin necrosis, but no elbow was affected by insufficiency of the triceps.

Patients were followed for a mean of 42 months (24 to 77). The mean post-operative Japanese Orthopaedic Association Elbow Score was 90.8 (51 to 100) and the mean Mayo Elbow Performance score 93.8 (65 to 100). The mean post-operative flexion/extension of the elbow was 135°/-8°. The Manual Muscle Testing score of the triceps was 5 in 23 elbows and 2 in two elbows (one patient). The mean alignment of the implants examined by 3D-CT was 2.8° pronation (standard deviation (sd) 5.5), 0.3° valgus (sd 2.7), and 0.7° extension (sd 3.2) for the humeral component, and 9.3° pronation (sd 9.7), 0.3° valgus (sd 4.0), and 8.6° extension (sd 3.1) for the ulnar component. There was no radiolucent line or loosening of the implants on the final radiographs.

The triceps-sparing ulnar approach allows satisfactory alignment of the implants, is effective in preventing post-operative triceps insufficiency, and gives satisfactory short-term results.

This pilot study reports the clinical outcomes of a combination of partial subscapularis tendon transfer and small-head hemiarthroplasty in patients with rotatator cuff arthropathy. A total of 30 patients (30 shoulders; eight men and 22 women) with a mean age of 74 years (55 to 84) were assessed at a mean follow-up of 31 months (24 to 60). The inclusion criteria were painful cuff tear arthropathy with normal deltoid function and a non-degenerative subscapularis muscle and tendon and a preserved teres minor.

Outcome was assessed using the University of California Los Angeles score, the Japanese Orthopaedic Association score, and the Oxford Shoulder Score. Radiographic measurements included the centre of rotation distance and the length of the deltoid.

All clinical scores were significantly improved post-operatively. The active flexion and external rotation improved significantly at the most recent follow-up (p < 0.035). Although the mean centre of rotation distance changed significantly (p < 0.001), the mean length of the deltoid did not change significantly from the pre-operative value (p = 0.29). The change in the length of the deltoid with < 100° flexion was significantly less than that with > 100° (p < 0.001).

Progressive erosion of the glenoid was seen in four patients. No patient required revision or further surgery.

A combination of partial subscapularis tendon transfer and small-head hemiarthroplasty effectively restored function and relieved pain in patients with rotator cuff arthropathy.

Various surgical treatment were reported on rheumatoid shoulder. However, there were no recommended surgeries in the Japanese 2nd basic published text of rheumatoid disease. We had performed total shoulder arthroplasty(TSA) and humeral head replacement (HHR) in patient with Rheumatoid shoulder from 1992.

The aim of this study was to compare the outcome of humeral head replacement, 2nd generation TSA and 3rd generation TSA in patients followed more than 5 years with rheumatoid shoulder.

Material & Method

From 1992–2007, we performed shoulder arthroplasty in 42 shoulders in 40 patients. Six cases were not able to follow due to die and lost. All 36 shoulders in 34 patients could be followed with x-ray examinations more than 5 years. Averaged follow-up period was 8.6 years (range 5–14.5). HHR with intact cuff performed in 10 shoulders, 2nd generation TSA with intact cuff in 10, 3rd generation TSA in intact cuff in 10 and HHR with muscle tendon transfer in 6 shoulders. The shoulder score of Japanese Orthopaedic Association)JOA score. Modified Neer classification, ROM, lucent lines in X-ray and complications were investigated.

Results

In JOA score, 3rd generation TSA revealed highest score (84 points). Also, in Modified Neer classification, excellent results were obtained 50% of cases in 3rd generation TSA. On the other hand, HHR with muscle tendon transfer group has no cases of excellent results. In flexion & external rotation, 3rd generation TSA had achieved satisfactory results. In X-ray, all glenoid component had a lucent line around the keel type glenoid in 2nd generation TSA. However, only 1.6 points in Lazarus claasification revealed in peg type component in 3rd generation TSA. No nerve injuries and instability were found after surgery. However, two infections and two glenoid resurfacing need after surgery.

Introduction

Although Total elbow arthroplasty (TEA) generally provides favorable clinical outcomes, its complications have been reported with high rate compared with other joints. Previously, we used the Bryan & Morrey approach in TEA, which included separating the triceps muscle subperiosteally from the olecranon; however, since 2008, in order to prevent skin trouble and deficiency of the triceps, we performed TEA by MISTEA method, which required no removal of the subcutaneous tissue in the region of the olecranon and no release or stripping of the triceps tendon.

Objectives

The purpose of this study was to examine the utility of the MISTEA method by evaluating and comparing muscle strength and complications by using both the Bryan & Morrey approach and MISTEA method.

Introduction

We performed humeral head replacement (HHR) with smaller head for closing the cuff defect in patients of cuff tear arthropathy (CTA). And also, if the cuff defect could not close by decreasing the head size, we add muscle tendon transfer such as latissimus dorsi transfer for posterosuperior defect and pectoralis major transfer for anterosuperior defect.

Aim

The purpose of this study was to investigate clinical and functional outcomes of this procedure for CTA according to Hamada-Fukuda classification.

Introduction

In recently, Reverse shoulder arthroplasty (RSA) in patients with irreparable rotator cuff tear has been worldwidely performed. Many studies on RSA reported a good improvement in flexion of the sholulder, however, no improvement in external rotation (ER)and internal rotation motion (IR). Additionally, RSA has some risks to perform especially in younger patients, because high rates of complications such as deltoid stretching and loosening, infection, neurologic injury, dislocation, acromial fracture, and breakage of the prosthesis after long-term use were reported. Favard et al noted a 72% survival with a Constant-Murley score of <30 at 10 years with a marked break occurring at 8 years. Boileau et al noted caution is required, as such patients are often younger, and informed consent must obviously cover the high complication rate in this group, as well as the unknown longer-term outcome. Its use should be limited to elderly patients, arguably those aged over 70 years, with poor function and severe pain related to cuff deficiency. We developed a novel strategy in 2001, in which we used the humeral head to close the cuff defect and move the center of rotation medially and distally to increase the lever arm of the deltoid muscle.

Aim

The aim of this study was to investigate clinical outcome of our strategy for younger patients with an irreparable rotator cuff tear.

Purpose

In total elbow arthroplasty (TEA), especially for elbows with condyle defect due to rheumatoid arthritis or trauma, determination of rotation alignment of implants is often difficult. To develop a navigation system for TEA, selecting bony landmarks that can be identified intraoperatively is important. Therefore, we developed a new roentgen free navigation system such as special alignment jigs for TEA based on CT data of normal elbows. The aim of this study was to evaluate alignments of implants after MIS-TEA using the new systems. And also, we reported that 6 bony landmarks on the elbow showed small variability in normal elbows by CT examinations and were considered to be usable as intraoperative landmarks for determining rotational position of implants last year. Especially in RA elbow, posterior aspect of humerus and ulnar aspect of proximal part of ulna were able to be identified even if there is a large bone defect that extends to the lateral or/and medial epicondyle.

We used a new roentgen free navigation system in TEA with using Solar elbow from 2009. The aim of this study was to evaluate alignments of implants after MIS-TEA using the new systems by CT examinations.

MATERIALS AND METHODS

For determination of alignment and anatomical landmarks to develop the jigs, 3D-CT data of 11 normal elbows was investigated. The posterior aspect of humeral shaft and ulnar aspect of proximal ulna were selected as bony landmarks. Because these can be identified intraoperatively and remain in elbows with extensive bone loss. MIS-TEA with Solar Elbow (Stryker) using these new systems were investigated with postoperative 3D-CT in 14 elbows of 13 patients. Their average age was 68.8 years old. Basic diseases were 10 rheumatoid arthritis and 4 distal humerus injuries. The alignments of humeral and ulnar component were measured on postoperative 3D-CT.

In recently, reverse shoulder arthroplasty for rotator cuff deficient arthritis is widely used in the world. However, a high complication rate was reported and worried about long-term results after reverse shoulder arthroplasty. From 2001, we performed a novel strategy for these cases such as rotator cuff reconstruction w/ or w/o muscle transfer and a humeral head replacement with using smallest head to decrease joint volume. The aim of this study was to investigate with clinical outcomes after this surgery more than two years follow-up.

Materials & methods

Fifty six shoulders underwent humeral head replacement (HHR) with or without tendon transfer for cuff tear arthropathy was able to follow-up more than two years. The mean age was 74 years (60 to 83 years). 42 cuff tear arthropathy, 6 RA, 5 re-tear after cuff repair with arthritis, and 1 arthritis after infection were included. Coracoacromial arch preserved Superior approach with preserving coracoacromial arch was used for replacement the humeral stem and head. Almost of the cases could be repaired with using a smallest head because of the height of humeral head and joint volume were decreased. However, when rotator cuff remained in irreparable condition, a latissimus dorsi tendon or a pectoralis major tendon from same shoulder was transferred for cuff reconstruction. The patients were divided by 2 groups; 36 shoulders of HHR without tendon transfer and 20 shoulders of HHR with tendon transfer. Each patient was evaluated with Japan Orthopaedic Association score (JOA score) and modified Neer's limited goals rating scale after a least 2 year of follow-up.

Results

In all cases, preoperative severe pain was dramatically improved. JOA score improve from 40.2 preoperatively to 80.2 postoperatively. Twelve shoulders estimated as excellent in modified Neer's classification, 34 in satisfactory and 10 in unsatisfactory. Half of cases with RA were unsatisfactory results. Postoperative active flexion statistically improved compared to preoperative range of motion. Averaged postoperative flexion was 136 degrees (preop.;68.8) and postoperative external rotation was 28.6 degrees (preop.;13.2). However, there was no significant difference of external rotation in the HHR group between pre and postoperative evaluation. The radiographic evaluation showed four cases of glenoid erosion. One case had arthroscopic Suprascapular nerve release eight years after surgery.

From 1996, we were added fenestration between coronoid fossa, and olecranon fossa at the time of debridement arthroplasty termed extensive debridement arthroplasty with medial and lateral approach.The purpose of this study is to investigate clinical results of extensive debridement arthroplasty.

17 cases could be followed more than two years. Their averaged age was 57.3 years old. Two elbows had a previous history of debridement arthroplasty. In preoperative averaged flexion angle was 105 and averaged extension was 28C Clinical evaluation was performed with the elbow score of Japanese Orthopedic Association Preoperative averaged JOA score was 54.6 points In ray study we investigated whether the fenestration was open or closed.

In all cases, their symptoms improved D All patients returned to their former occupations satisfied with the clinical results Infection postoperative fracture and ectopic ossification were not observed.The averaged JOA score was 91 points Postoperative averaged flexion was 127 averaged extention was 12_Improvement of extension was 16 and that of flexion was 22 Closure of the fenestration was observed in five elbows Osteophyte formations of the coronoid process and olecranon was seen in 4 elbows

The JOA score of pain and ROM of these results were superior compared with any reports of debridement arthroplasty.The JOA score and results of ROM were superior when the fenestration was open.To maintain the fenestration hole open some modification will be necessary

Short term results of extensive debridement arthroplasty showed satisfactory results in terms of pain relief and Improvement of ROM, especially in extension.

We have reviewed 20 patients stage-IIIB and stage-IV Kienböck’s disease in order to examine the efficacy of two forms of radial osteotomy, namely radial wedge osteotomy and radial shortening. Lateral closing wedge osteotomies and radial shortenings were carried out on 11 and nine patients, respectively. There were no preoperative differences with respect to age, gender, and radiological stage.

After a mean follow-up of 29 months, all patients, in both groups, had either a good or an excellent outcome. After the lateral closing wedge osteotomy, the radioscaphoid angle significantly increased and the St̊hl index significantly decreased. Progression of the degenerative changes at the radioscaphoid joint was found in two patients in this group. By contrast, there were no significant changes in any radiological parameters after radial shortening. Both procedures gave acceptable clinical results in stage-IIIB and stage-IV Kienböck’s disease.
