BACKGROUND:

Bony healing of tuberosities around shoulder prostheses is difficult to obtain in the elderly patient. We hypothesized that reattachment of the tuberosities, performed in combination with bone grafting, around a specific reverse shoulder fracture-prosthesis (RSFP) would favour improved tuberosity healing and shoulder mobility in elderly patients with displaced proximal humerus fractures.

METHODS:

We included 49 patients (50 shoulders)(45 female, 4 male) in this prospective study. Mean (± SD) age 80 ± 4 years (range, 70–88). Clinical evaluation consisted of ROM, VAS (pain), Constant scores, patient satisfaction (Subjective Shoulder Value (SSV)) and noted complications. Radiological evaluation consisted of tuberosity healing and component loosening. Mean follow-up 18 ± 8 months (12–39).

Purpose: We hypothesized that lateralization of the RSA, with a glenoid bone graft taken from the osteotomised humeral head, would prevent those problems without increasing torque on the glenoid component by keeping the center of rotation within the glenoid. The objectives of this study were to describe the results of the first 12 patients that underwent a bony increased-offset RSA (BIO RSA).

Method: Thirty-six shoulders in 34 consecutive patients with cuff tear arthritis (mean age 72 years, range 52–86 years) received a BIO RSA, consisted of a RSA incorporating an autogenous humeral head bone graft placed beneath the glenoid baseplate. A baseplate with a lengthened central peg (+25 mm) was inserted in the glenoid vault, securing the bone graft beneath the baseplate and screws. All patients underwent clinical and radiographic (computed tomography) review at a minimum 1-year follow-up.

Results: All patients were satisfied or very satisfied and all had no or slight pain. Mean active elevation increased from 72° to 142° (p< 0.05), external rotation from 10° to 18° (p< 0.05) and internal rotation from L4 to L3 (p> 0.05). Constant Score improved from 27 to 63 points (p< 0.05). The Subjective Shoulder Value (SSV) increased from 27% to 73% (p< 0.05). Radiographically, the graft healed to the native glenoid in all cases and no graft resorption under the baseplate was observed. Complications included one patient with scapular notching (stage 1) and one patient with previous radiotherapy had a deep infection. No postoperative instability, and no glenoid loosening were observed.

Conclusion: The use of an autologous bone graft harvested from the humeral head can lateralize the center of rotation of a RSA while keeping the center of rotation at the glenoid bone-prosthesis interface. The clinical advantages of a BIO RSA are a decrease in scapular notching, enhanced stability and mobility, and improved shoulder contour while keeping the center of rotation at the glenoid bone-prosthesis interface. This bony lateralization allows maintenance of the principles of Grammont and seems to be more appropriate than prosthetic lateralization. These promising early results of this novel procedure warrant further investigation.

Purpose of the study: Completely arthroscopic repair of rotator cuff tears is widely considered as the standard treatment. We reviewed a multicentric retrospective series of patients.

Material and methods: This series of arthroscopic repairs of full-thickness tears of the supraspinatus and infraspinatus were assess with the Constant score together with arthroMRI or arthroscan at one year follow-up at least. Data were analyzed with SPSS10. The series included 576 patients who underwent surgery from January 2001 to June 2003. Mean age was 57.7 years, 52% males and 60% manual laborers. Mean preoperative Constant score was 46.4/100 (r13.4). The tear was limited to the supraspinatus in 69% of patients with extension to the upper third of the infraspinagus for 23.5% and to all tendons for 7.5%. The supraspinatus tear was distal in 41.7% of patients, intermediary for 44%, and retracted for 14.3%. Arthroscopic repair was performed in all cases, with locoregional anesthesia for 60.9%. Implants were resorbable for 33% and metallic for 62.1%. Acromioplasty was performed for 92.7% and capsulotomy for 14.9%.

Results: The mean subjective outcome was scored 8.89/10. The Constant score improved from 46.3±13.4 to 82.7±10.3 with 62% of patients being strictly pain free. The force score improved from 8.5±3.7 to 13.6±5.4. Outcome was excellent or very good for 94% of the shoulders at 18.5 mean follow-up. The rate of complications was 6.2% with 3.1% of patients presenting prolonged joint stiffness, 2.7% reflex dystrophy, 0.2% infection and 0.2% implant migration. The cuff was considered normal in 55.7% of the shoulders with an intratendon addition image for 19%, i.e. 74.7% non-torn cuffs. A point leakage was noted in 9.5% with pronounced leakage in 15.7%, i.e. 25.2% recurrent tears.

Discussion and conclusion: The functional outcome obtained after arthroscopic repair of rotator cuff tears is good. Arthroscopy has the advantage of a low rate of complications yet provides good clinical and anatomic results. Age is correlated with functional outcome and healing, but should not be considered as a contraindication.

Purpose of the study: The objective of this study was to identify clinical and anatomic factors which could affect the outcome of tendon healing after arthroscopic repair of rotator cuff tears.

Material and methods: This prospective cohort study included 122 patients who underwent arthroscopic treatment between May 1999 and September 2002. One hundred twelve patients (114 shoulders) were reviewed (93.4%). Mean age at surgery was 61 years. An arthroscan (78% of patients) or magnetic resonance imaging (MRI) were performed six months postoperatively. Mean follow-up was 24 months (range 13–46 months).

Results: Rotator cuff tears healed completely in 64% of the shoulders (n=73) and partially in 7% (n=8). No healing was observed in 29% (n=33). The Constant score was 49.8 preoperatively and 82.4 at last follow-up (p< 0.0001). Cuff healing improved clinical outcome with a Constant score of 85 points versus 77, particularly for force, 14.5 points versus 10 without healing. Four factors were statistically predictive of tendon healing: duration from symptom onset to operation (24 months for healed tears versus 37 months, p< 0.05); age at cuff repair (81% healed tears in patients aged less than 50 years versus 50% for patients aged over 65 years, p< 0.002); sagittal extension of the rotator interval or extension to the upper third of the infrascapularis (45% healed tears versus 79% without anterior extension, p< 0.0001); fatty degeneration (69% of healed tears for Goutallier grade 0 versus 38% for grade 1 and 2, p< 0.01).

Conclusion: This study demonstrated that four factors can predict tendon healing: time to treatment, age at surgery, anterior extension of the tear, fatty degeneration.

Purpose of the study: A statistical analysis of correlations between clinical outcome and anatomic results after arthroscopic repair of rotator cuff tears.

Material and methods: This multicentric series of rotator cuff tears was limited to the supraspinatus and infraspinatus. The statistical analysis searched for correlations between the clinical outcome (Constant score) and anatomic results (arthroscan and arthroMRI). The series included 576 patients, mean age 57.7 years, 52%μ males and 60% manual laborers. The tear was limited to the suprapsinatus in 69% of patients, with extension to the upper third of the infraspinatus in 23.5% and all tendons in 7.5%. The supraspinatus tear was distal in 41.7% of patients, intermediary in 44% and retracted in 14.3%. Fatty degeneration of the supraspinatus was noted grade 0 in 59.7%, 1 in 27.1%, 2 in 10.8% and 3 in 2.4%.

Results: The Constant score (46.3 preoperatively and 82.7 postoperatively) was strongly correlated with successful repair. The correlation was found for force, motion, and activity, but not for pain. The clinical outcome was correlated with extension, retraction, cleavage, and degeneration of the preoperative injury. The anatomic result was statistically less favorable for older, more extended, retracted, and cleaved tears or tears associated with fatty degeneration. Age was correlated with the extent of the initial tear and also with less favorable clinical and anatomic results. Work accidents were correlated with less favorable clinical outcome.

Discussion: The large number of anatomic controls with contrast injection facilitated demonstration of several statistically significant correlations. This enabled disclosure in a single series of evidence confirming earlier reports in the literature: repair of cuff tears improves the overall functional outcome for massive tears; the anatomic result depends on the size of the initial tear; pre-operative fatty degeneration is an important prognostic criteria; cuff healing is age-dependent.

Conclusion: Study of anatamoclinical correlations helps guide therapeutic decision making and enables the establishment of reliable prognostic criteria after arthroscopic repair of rotator cuff tears.

Using radiography and computer tomography (CT) we studied the morphology of 83 hips in 69 Caucasian adults with osteoarthritis secondary to developmental dysplasia of the hip (DDH). A previously published series of 310 hips with primary osteoarthritis was used as a control group. According to the Crowe classification, 33 of the dysplastic hips were graded as class I, 27 as class II and 23 as class III or class IV.

The intramedullary femoral canal had reduced mediolateral and anteroposterior dimensions in all groups compared with the control group. Only in Crowe class II hips was the femoral neck-shaft angle increased. The proximal femur had more anteversion in all the developmental dysplasia of the hip groups, ranging from 2° to 80°. Templated measurement of acetabular dimensions for plain radiography closely matched measurements taken by CT.

The results of our study confirm the observations previously confined to the Japanese population.

Purpose: We hypothesised that the rate of tendon healing after arthroscopic repair of full-thickness tears of the supraspinatus is equivalent to that obtained with open techniques reported in the literature.

Material and methods: We studied prospectively a cohort of 65 patients with arthroscopically repaired full-thickness tears of the supraspinatus. The patients were reviewed a mean 19 months (12–43) after repair. At arthroscopy, patients were aged 59.5 years on average (28–79). Bone-tendon sutures were performed with resorbable thread and self-locking anchors positioned on the lateral aspect of the humerus. Repair was protected with an abduction brace for six weeks. Forty-one patients (63%) accepted an arthroscan performed six months to two years after arthroscopy to assess tendon healing.

Results: Ninety-four percent of the patients were satisfied with the outcome. The mean Constant score was 51.6±10.6 points preoperatively and 80.2±13.2 at last follow-up (p< 0.001). The arthroscan showed that the rotator cuff had healed in 70% of the cases (29/41). The supra-spinatus had not healed on the trochiter in eight cases (25%) and was partially healed in two (5%). The size of the residual tendon defect was less than the initial tear in all cases except one. The rate of patient satisfaction and function was not significantly different if the tendon had healed (Constant score 81.3/100, satisfaction 93%) or if there was a residual tendon defect (Constant score 77.5/100, satisfaction 92%). Shoulder force in patients with a healed tendon (6±1.9 kg) was better than in those with a tendon defect (4.5±2.8 kg), but the difference was not significant. Factors affecting tendon healing were age > 65 years (43% healing, p< 0.02), and wide tears.

Conclusion: Arthroscopic repair of isolated supraspinatus tears enables tendon healing in 70% of cases as demonstrated by arthroscan. This rate was equivalent to those reported in historical series of open repair. Patients aged over 65 years had significantly less satisfactory healing. The absence of tendon healing does not compromise functional and subjective outcome despite reduced force.
