Article Synopsis
  • The wrapping technique aims to protect nerves from scar tissue and enhance their function, particularly after neurolysis for conditions like cubital tunnel syndrome (CuTS).
  • A study analyzed the effectiveness of AxoGuard® nerve protector, a porcine-derived matrix used during revision surgeries for CuTS, comparing outcomes between patients who had only surgery versus those who received the nerve wrapping.
  • Results showed that the wrapping group had significantly better clinical improvement, with 84.4% achieving excellent or good outcomes and no complications related to the implant, indicating that PECM wrapping may help reduce nerve scarring and improve nerve function.

Background: The Eaton-Littler ligament reconstruction is widely used for thumb carpometacarpal (CMC) instability, yet the existing literature lacks a thorough analysis of the outcomes for nontraumatic instability. This study aimed to assess the outcomes of the Eaton-Littler ligament reconstruction and to identify prognostic factors associated with postoperative pain.

Methods: Patients with nontraumatic CMC joint instability, unresponsive to conservative treatment, were included in this prospective study.

Background: Following the repair of a mixed peripheral nerve, functional recovery requires successful nerve regeneration across the repair site and, eventually, reinnervation of distal targets. Reliably determining a failing nerve repair so that revision may be performed before irreversible muscle atrophy remains a challenge in peripheral nerve surgery. This study aimed to ascertain whether any commonly used clinical examination tests during surveillance after nerve repair can detect a failing repair and prompt earlier salvage intervention.

Background: The authors hypothesized that the 3-ligament tenodesis (3-LT) procedure is still sufficient-even in scapholunate advanced collapse (SLAC) cases-to reduce pain and improve wrist function. The authors compared patient-reported outcomes of scapholunate interosseus ligament (SLIL) injury patients with SLAC, to SLIL injury patients treated with 3-LT, and then to patients who underwent proximal row carpectomy (PRC), as a control group.

Methods: The authors included all patients with a traumatic SLIL injury and associated SLAC components treated with 3-LT and completed patient-rated wrist evaluation (PRWE) questionnaires preoperatively and at 12-month follow-up.

Background: Multiple studies have shown that more-positive outcome expectations are associated with better treatment outcomes. Although this has not been shown to represent a causal relationship, there nonetheless is an interest in positively modifying outcome expectations to improve treatment outcomes. However, little is known about what is independently associated with outcome expectations in clinical practice.

Background: A small proportion of patients treated for a hand or wrist condition are also involved in a personal injury claim that may or may not be related to the reason for seeking treatment. There are already indications that patients involved in a personal injury claim have more severe symptoms preoperatively and worse surgical outcomes. However, for nonsurgical treatment, it is unknown whether involvement in a personal injury claim affects treatment outcomes.
