Massive posterosuperior cuff tears (mRCT) retracted to the glenoid are surgically challenging and often associated with high retear rates. Primary repair is a less-favourable option and other salvage procedures such as SCR and tendon transfers are used. This study presents clinical and radiological outcomes of muscle advancement technique for repair of mRCT.

Sixty-one patients (mean age 57±6, 77% males and 23% females) (66 shoulders) underwent all-arthroscopic rotator cuff repair that included supraspinatus and infraspinatus subperiosteal dissection off scapular bony fossae, lateral advancement of tendon laminae, and tension-free double-layer Lasso Loop repair to footprint.

Pre-and post-operative range of motion (ROM), cuff strength, VAS, Constant, ASES, and UCLA scores were assessed. Radiologic assessment included modified Patte and Goutallier classifications. All patients had MRI at 6 months to evaluate healing and integrity of repair was assessed using Sugaya classification with Sugaya 4 and 5 considered retears.

Advanced fatty degeneration (Goutallier 3-4) was present in 44% and 20% of supraspinatus and infraspinatus. Tendon retraction was to the level of or medial to glenoid in 22%, and just lateral in 66%. 50.8% mRCT extended to teres minor. Subscapularis was partially torn (Lafosse 1-3) in 46% and completely torn (Lafosse 4-5) in 20%.

At mean follow-up (52.4 weeks), a significant increase in ROM, Relative Cuff Strength (from 57% to 90% compared to contralateral side), VAS (from 4 ±2.5 to 1±1.7), Constant (50±17.8 to 74 ±13.0), ASES (52 ±17.5 to 87 ±14.9), and UCLA (16± 4.9 to 30 ±4.9) scores were noted. There were six retears (10%), one failure due to P. acnes infection. 93% returned to pre-injury work and 89% of cases returned to pre-injury sport. Satisfaction rate was 96%.

Muscle advancement technique for mRCT is a viable option with low retear rates, restoration of ROM, strength, and excellent functional outcomes.

Complications such as implant loosening, infection, periprosthetic fracture or instability may lead to revision arthroplasty procedures. There is limited literature comparing single-stage and two-stage revision shoulder arthroplasty. This study aims to compare clinical outcomes and cost benefit between single-stage and two-stage revision procedures.

Thirty-one revision procedures (mean age 72+/-7, 15 males and 16 females) performed between 2016 and 2021 were included (27 revision RSA, 2 revision TSA, 2 failed ORIFs). Two-stage procedures were carried out 4-6 weeks apart. Single-stage procedures included debridement, implant removal and washout, followed by re-prep, re-drape and reconstruction with new instrumentations. Clinical parameters including length of stay, VAS, patient satisfaction was recorded preoperatively and at mean 12-months follow up. Cost benefit analysis were performed.

Seven revisions were two-stage procedures and 24 were single-stage procedures. There were 5 infections in the two-stage group vs 14 in the single-stage group. We noted two cases of unstable RSA and 8 other causes for single-stage revision. Majority of the revisions were complex procedures requiring significant glenoid and/or humeral allografts and tendon transfers to compensate for soft tissue loss. No custom implants were used in our series.

Hospital stay was reduced from 41+/-29 days for 2-stage procedures to 16+/-13 days for single-stage (p<0.05). VAS improved from 9+/-1 to 2+/-4 for two-stage procedures and from 5+/-3 to 1+/-2 for single-stages. The average total cost of hospital and patient was reduced by two-thirds. Patient satisfaction in the single-stage group was 43% which was comparable to the two-stage group.

All infections were successfully treated with no recurrence of infection in our cohort of 31 patients. There was no instability postoperatively. 3 patients had postoperative neural symptoms which resolved within 6 months.

Single-stage procedures for revision shoulder arthroplasty significantly decrease hospital stay, improve patients’ satisfaction, and reduced surgical costs.

Acromioclavicular joint (ACJ) dislocations is a common disorder amongst our population for which numerous techniques have been described. It is thought that by using this novel technique combining a CC and AC repair with a reconstruction will result in high maintenance of anatomical reduction and functional results.

12 consecutive patients ACJ dislocations were included. An open superior clavicular approach is used. Firstly, the CC ligaments are repaired after which a CC reconstruction is performed using a tendon allograft. Secondly, the AC ligaments are repaired using an internal brace construct combined with a tendon allograft reconstruction (Figure 1).

The acute:chronic ratio was 6:6. Only IIIB, IV and V AC-joint dislocations were included. The Constant-Murley Score improved from 27.6 (8.0 – 56.5) up to 61.5 (42.0 – 92.0) at 12 months of follow up. Besides one frozen shoulder from which the patient recovered spontaneously no complications were observed with this technique. The CCD was reduced from 18.7 mm (13.0 – 24.0) to 10.0 mm (6.0 – 16.0) and 10.5 mm (8.0 – 14.0) respectively 12 weeks and 12 months postoperatively.

There is some evidence, suggesting to address as well as the vertical (coracoclavicular (CC) ligaments) as the horizontal (acromioclavicular (AC) ligaments) direction of instability. This study supports addressing both entities however comparative studies discriminating chronic as acute cases should be conducted to further clarify this ongoing debate on treating ACJ instability.

This study describes a novel technique to treat acute and chronic Rockwood stage IIIB – IV ACJ dislocations with promising short-term clinical and radiological results. This suggests that the combined repair and reconstruction of the AC and CC ligaments is a safe procedure with low complication risk in experienced hands. Addressing the vertical as well as horizontal stability in ACJ dislocation is considered key to accomplish optimal long-term results.

Introduction Chicken studies implicate pinealectomy within a week of hatching as a cause of scoliosis. The nature of the scoliosis has been demonstrated to be similar to that of human idiopathic scoliosis. Scoliosis was not induced following pinealectomy in Rhesus monkeys (primate model). No human studies have been reported. The aim of this study is to determine if idiopathic scoliosis is associated with treatment for pineal lesions (presumably resulting in pinealectomy) in a human paediatric population.

Methods A medical records search was performed in five Australian States for pineal lesions. Identified patients underwent clinical or radiological evaluation for scoliosis. Pathology varied from germ cell tumour, germinoma, pineoblastoma, teratoma to a pineal cyst and an epidermoid cyst. Treatment ranged from biopsy/ extirpation to radiotherapy/chemotherapy.

Results Of 48 identified patients, thirteen are deceased. No scoliosis was present in the last imaging of the deceased. The mean age at presentation was 9.7 years (range 1–18 years). Ten are female. Two males have idiopathic scoliosis (4.2%). One has a 12° right upper thoracic curve (with 32° kyphosis) and the other has a 60° right thoracolumbar curve, requiring a two-stage arthrodesis

Discussion Although the incidence of idiopathic scoliosis in this cohort is greater than expected from Caucasian population studies (2–3%), it is not typical idiopathic-type, which has a female preponderance of larger deformities. New-born chicken studies demonstrate an incidence of between 50 and 100% scoliosis in the three months following pinealectomy. Chickens of both sexes are involved. Fundamental differences exist between chicken and human/primate models including the age at pinealectomy and the anatomical site of the pineal gland. Chickens have a naturally lordotic thoracic spinal curvature whilst humans/primates have a naturally kyphotic thoracic spine. Adolescents with idiopathic scoliosis have either thoracic hypokyphosis or a thoracic lordosis. Contrary to current beliefs, no causal link can be established between pineal lesions and the development of idiopathic scoliosis in a paediatric population.
