Shoulder Reconstruction

Bota, O., et al. (2023). "Complex Functional Posttraumatic Shoulder Reconstruction Using Shoulder Arthroplasty and a Pedicled Innervated Latissimus Dorsi Flap—A Case Report and Literature Review." Orthopaedic Surgery 15(8): 2181-2186  https://onlinelibrary.wiley.com/doi/abs/10.1111/os.13575

                Background The shoulder joint is one of the most freely movable joints in the human body and has therefore high importance for upper limb functionality. Several techniques have been developed to replace the glenohumeral joint including humeral hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty, depending on the underlying pathology. For the soft tissue reconstruction, the innervated latissimus dorsi musculocutaneous flap is a reliable solution flap in shoulder and arm reconstruction. Case presentation We present the case of a 16-year-old male patient with a complete destruction of the shoulder joint and soft tissues after ballistic trauma. We performed the reconstruction of the shoulder joint using a humeral hemiarthroplasty with a mesh fixation to the remaining glenoid. The soft tissue coverage and the restoration of the deltoid muscle function were insured with a pedicled innervated latissimus dorsi musculocutaneous flap. One year postoperatively, the patient showed a good function of the shoulder joint with an excellent aesthetical result and no pain. Conclusion The pedicled latissimus dorsi musculocutaneous flap can safely restore the shoulder function, while the humeral hemiarthroplasty with mesh fixation can be a reliable solution for the reconstruction of a completely destructed shoulder joint.

                Purpose The objective of this study was to compare the outcomes of a single nerve transfer (SNT) with double nerve transfer (DNT) in the restoration of shoulder function in patients with upper (C5-6) or extended upper-type (C567) brachial plexus injuries. Methods A retrospective review of patients with C5-6 or C567 brachial plexus injuries operated on with nerve transfers from January 1, 2005, to December 31, 2017, was completed. The outcomes between SNT and DNT groups were evaluated with the Filipino Version of the Disabilities of the Arm, Shoulder, and Hand (FIL-DASH) scores, pain scores, muscle strength recovery, and range of motion. A subgroup analysis on surgical delay (< or ≥ 6 months), diagnosis (C5-6 or C567), and length of follow-up (< or ≥ 24 months) was also performed. All statistical significance was set at P < .05. Results A total of 22 patients with SNT and 29 with DNT were included in this study. There was no significant difference between the SNT and DNT groups as to postoperative FIL-DASH scores, pain, recovery of ≥M4, and range of motion for shoulder abduction and external rotation, although the absolute values for shoulder function were greater in the DNT than the SNT group. There was no significant difference between the SNT and DNT groups for surgical delay, diagnosis, and length of follow-up. A stronger recovery of ≥M4 for external rotation was observed in the DNT group compared to the SNT group if nerve transfer was performed in less than 6 months (86% vs 41%). Conclusions The outcomes for shoulder function between the 2 groups were similar, although the DNT group performed slightly better, especially with external rotation. Patients operated on less than 6 months from injury will benefit more from DNT for shoulder function, especially for external rotation. Clinical relevance Double nerve transfer may result in improved shoulder function.

                Background: Single injection ropivacaine interscalene anesthesia (ISA) is frequently used in Latarjet reconstruction to enhance post-operative analgesia. A potential limitation is the occurrence of severe rebound pain on block resolution. We investigated the effect of intravenous magnesium on post-operative pain, particularly at the transition of block resolution to multimodal analgesia. Methods: Elective patients (n = 40) having Latarjet open shoulder reconstruction were randomised to receive either intravenous magnesium sulphate 50 mg/kg (M) or normal saline (S) before induction. Post-operatively, a standardised analgesic regimen was used, and post-operative pain was recorded using a verbal numerical rating assessment (VNRA) score. Requirement for injected opioid analgesia was recorded. Results: ISA provided longstanding analgesia in all patients with block duration slightly prolonged in the magnesium group (16.7(1.0) (S), 17.8(1.3) h (M), p = 0.049). Magnesium resulted in less rebound pain following ISA resolution (VNRA 4.0 (0.6) M, 6.2 (0.8) S, p = 0.03) and lower pain intensity at 24 h. Four patients had nausea and two required rescue opioid injection. Conclusion: Magnesium before Latarjet surgery results in less rebound pain following ropivacaine block and improves post-operative analgesia. Magnesium may be indicated in major upper limb surgery, where significant pain intensity is anticipated. Level of evidence: Treatment study; Randomised blinded; Level 2.
