Structural and Functional Results of Subscapularis and Conjoint Tendon After Latarjet Procedure at 8-Year Average Follow-up

Background: The Latarjet procedure involves initial dissection through a longitudinal split of the subscapularis tendon with only a final partial closure to accommodate the transferred coracoid bone. Furthermore, by transferring the coracoid bone block to the anterior glenoid, the surgeon completely alters the resting and dynamic route of the attached conjoint tendon. The eventual structural and functional integrity of the subscapularis and conjoint tendons is currently unknown. Purpose: To examine the structural and functional integrity of the subscapularis and the conjoint tendon after the Latarjet procedure at an 8-year average follow-up. Study design: Case series; Level of evidence, 4. Methods: Twenty patients with anterior shoulder instability at a mean age of 30 years (range, 19-50 years) underwent the open Latarjet procedure. Clinical examination at the final follow-up included quantitative isometric measurement of abduction and internal rotation strength compared with the nonoperative side. Patients were assessed via radiograph examination and preoperative computed tomography. Final position and healing of the transferred coracoid bone block were evaluated using standard radiographs. At follow-up, the subscapularis and conjoint tendon were evaluated via magnetic resonance imaging (MRI) with metal artifact reduction techniques and via ultrasound. Results: Nineteen of the 20 shoulders remained stable at the final follow-up; there was 1 redislocation (5%) after 14 months. The mean Rowe score was 83 points (SD, 17.9 points), the mean Constant score was 85 points (SD, 8.1 points), and the Subjective Shoulder Value was 80% (SD, 18%). The mean abduction strength of the operative shoulder was 7.41 ± 2.06 kg compared with 8.33 ± 2.53 kg for the nonoperative side ( P = .02). The mean internal rotation strength at 0° for the operative shoulder was 8.82 ± 3.47 kg compared with 9.06 ± 3.01 kg for the nonoperative side ( P = .36). The mean internal rotation strength in the belly-press position for the operative shoulder was 8.12 ± 2.89 kg compared with 8.50 ± 3.03 kg ( P = .13). Four of 20 shoulders showed mild tendinopathic changes of the subscapularis tendon but no partial or complete tear. One patient exhibited fatty degeneration Goutallier stage 1. Conjoint tendon was in continuity in all 20 shoulders on MRI scans. Conclusion: Abduction, but not internal rotation strength, was slightly reduced after the Latarjet procedure at a mean of 8 years of follow-up. The subscapularis tendon was intact based on ultrasound examination, and the conjoint tendon was intact based on MRI scans. Subscapularis muscle girth relative to the supraspinatus muscle remained intact from preoperative measurements based on MRI scans.

OV01 A LOW-COST HERNIA MODEL FOR THE TRAINING OF THE SHOULDICE AND THE LICHTENSTEIN INGUINAL HERNIA REPAIR

Aim Based on an international European survey, residents prefer to study inguinal hernia repair through lectures or video-demonstrations or want to practice either on simulation or cadaveric models. Simulation models in inguinal hernia are scarce or expensive. Material and Methods A low-cost model was developed that can be produced everywhere with the aid of the instruction video: “How to build an inguinal hernia model”. Initially, the model was designed to practice the Lichtenstein technique but after some minor modifications (adding the conjoint tendon, enough slack in the transversalis fascia) it was also possible to practice the Shouldice technique on the same model. It only needs the removal of the stitches of the third and fourth layer before the Lichtenstein can be performed. Results The model was used for several studies with students and residents and proved to be realistic and was approved by an international survey among experienced hernia surgeons. It has been used once in a national training session of residents. Conclusions The video shows the execution of both procedures on the same model.

Plate Fixation for Irreducible Proximal Humeral Fractures in Children and Adolescents—A Single-Center Case Series of Six Patients

Background: Recommended treatment for severely displaced proximal humeral fractures in children is the closed reduction and percutaneous fixation by K-wires or intramedullary nailing. Methods: From January 2016 to January 2017 6, 21 children/adolescents (range 8 to 16 years) with proximal humeral fractures were treated surgically for severe displacement. In these six patients, several attempts of closed reduction were unsuccessful, and an open reduction was performed. The humeral head was fixed with a 3.5 mm T-plate without affecting the growth plate. Plate removal was performed at a mean interval of 132 days after initial surgery. Two years after initial surgery, the clinical outcome was assessed by the Constant–Murley score and QuickDASH score (including sport/music and work) and the shoulder joint was evaluated with a standardized sonographic examination for the rotator cuff and the conjoint tendon. Results: In all six patients, dorsal displacement of the fracture was irreducible due to the interposition of tendinous or osseous structures. Intraoperatively, the interposed structures were the long biceps tendon in two, periosteal tissue in two, a bony fragment in one, and the long biceps tendon together with the conjoint tendon in one case. At mean follow-up of 26 months (range 22 months to 29 months), patients showed very good clinical results with an excellent mean Constant–Murley score of 97.5 (range 91 to 100) and mean QuickDASH score (including sport/music and work) of 5.5 (range 0–20.8). An X-ray follow-up 6 weeks after surgery demonstrated early consolidation and correct alignment in all patients. A sonographic evaluation at 2 years post injury showed that the biceps and the conjoined tendon were intact in all patients. Conclusions: If a proximal humeral fracture is not reducible by closed means, a tissue entrapment (most likely biceps tendon) should be considered. Treatment with an open reduction and plate fixation yields very good clinical and radiological results and preserves interposed structures as the biceps and conjoint tendon.

Spigelian hernia with bilateral undescended (impalpable) testis in a child: rare scenario

Spigelain hernia (SH) is rarely seen in children. Various mechanisms has been described for the co-existence with cryptorchidism. A 4 month old boy, a known case of bilateral impalpable testes and intermittent right lower abdominal swelling was brought to paediatric emergency with complaints of excessive cry, poor feeding and irreducible right lower abdominal swelling - the swelling was a little higher than the usual inguinal hernia. On exploration, SH was seen coming off the deep ring then turning around the conjoint tendon and dissecting between internal oblique and external oblique aponeurosis. The hernia contained oedematous but viable gut with compression over the testicular vessels. Gut was viable. The testes was mobilized and fixed into the scrotum. Left testis was impalpable for which nubbin excision was done at a later date. A SH in the lower abdomen may be confused with a high inguinal hernia. In acute obstruction, emergent exploration and reduction is the cornerstone of treatment.

Laparoscopic iliopubic tract repair for pediatric inguinal hernia has very low recurrence: an Indian experience

BackgroundThe aim of this study is to document results of laparoscopic iliopubic tract (IPT) repair for inguinal hernia in the pediatric age group.MethodsHospital records of 190 children who underwent IPT repair between January 2015 and January 2020 were analyzed retrospectively for demographic details, variations between clinical, radiological and laparoscopic diagnosis, associated pathologies, operative time, hospital stay, postoperative complications and follow-up. The internal ring was narrowed by approximating IPT to conjoint tendon using 3-0 polypropylene continuous or interrupted suture.ResultsIn total, 238 IPT repairs were done under general anesthesia in 190 children aged between 1 and 17 years. 7.9% of children had phimosis, and three children had hydrocele. Three patients had undescended testis and another three IPT repairs were done in cases who presented with appendicitis. Contralateral patent processus vaginalis (CPPV) was detected at the time of laparoscopy in 18.3% of cases. Thus far, 166 children had been followed, and no recurrence was observed in any of these 96 of whom have completed more than 3 years after their surgery. However, two patients developed hernia on the contralateral side.ConclusionsLaparoscopy is beneficial to pick up CPPV. Laparoscopic IPT repair for pediatric inguinal hernia is reproducible and safe with the least recurrence reported thus far. However, further follow-up is needed. Moreover, development of contralateral hernia needs to be investigated.
