The Sauvé-Kapandji procedure is an established treatment option for distal radioulnar joint dysfunction. We retrospectively analysed 36 patients following Sauvé-Kapandji procedure between 1997 and 2013. Fifteen patients were available for a follow-up after a mean of 13 years (range 6 to 23). Six patients needed revision surgery because of ulnar stump instability. Radiographs and sonography were performed to quantify the instability of the proximal ulnar stump. These showed a radioulnar convergence of 8 mm without weight and 2 mm while lifting 1 kg. Sonographically, the proximal ulnar stump dislocated by 8 mm to the volar side while applying pressure to the palm, compared with 4 mm on the contralateral side. Sonographically measured ulnar stump instability showed a positive strong correlation with the Disabilities of the Arm, Shoulder and Hand questionnaire and Patient-Reported Wrist Evaluations and a negative strong correlation with grip strength and supination torque. Because of the high incidence of revision surgery due to instability of the proximal ulnar stump, we restrict the use of the Sauvé-Kapandji procedure only to very selected cases. IV.

Background: The most common postoperative complication of the Sauvé‒Kapandji (S-K) procedure is proximal ulnar stump instability. The distal oblique bundle (DOB) is a stable tissue used to stabilize the distal radioulnar joint. This study created finite-element models of the distal oblique bundle (DOB) to determine its effect on the proximal ulnar stump instability encountered during the Sauvé‒Kapandji procedure.

Background: High-level median or ulnar nerve injuries and repairs typically result in suboptimal re-innervation of distal muscles. Functioning Free Muscle Transplantation (FFMT) is increasingly recognized as an effective method to restore function in chronic muscle denervation cases. This study investigates the efficacy of using an additional FFMT, neurotized by lateral sprouting axons from a repaired high-level mixed nerve in the upper limb, to enhance distal hand function.

Peripheral nerve surgery, particularly in cases of nerve compression syndrome (NCS), necessitates a comprehensive evaluation of intraneural blood flow, as localized reductions in nerve perfusion are integral to the etiopathogenesis of such conditions. Although nerve perfusion is currently guided by morphologic characteristics, this assessment is subjective and prone to bias. Intraoperative fluorescence-assisted perfusion imaging with indocyanine green (ICG) is an established tool in flap and lymphatic surgery to objectively assess perfusion intraoperatively.

- - The one-bone forearm procedure is a promising treatment for severe forearm deformities, but traditionally faced issues like nonunion and infection; a modified technique was developed to improve union rates by enhancing fixation between key bone segments.
- - A study on 28 young patients with forearm supination contracture due to neonatal brachial plexus injury showed an average correction of 116° and a complete bone union rate within about 6.6 weeks, with 100% success and no complications reported.
- - This modified technique not only enables significant rotational correction but also demonstrates a low complication rate, making it a valuable option for treating severe supination deformities in children.

Background And Objectives: Choosing the correct site for a nerve biopsy remains a challenge due to nerve sacrifice and major donor site complications, such as neuroma, as seen in sural nerve biopsy. Selecting a deeper donor nerve can help in burying nerve stumps in deep soft tissues, preventing neuroma. Moreover, using an expendable, deeply situated motor nerve can aid indiagnosis when a motor neuropathy is suspected.
