Introduction: Although multiple advances have been made in finger defect reconstruction, cross-finger flaps remain an important reconstructive tool. However, data on long-term results are scarce in the literature. This study aimed to assess the clinical and subjective long-term outcomes of patients who underwent cross-finger flap reconstruction for palmar digital and fingertip defects.

Patients and methods: Between January 2003 and July 2022, 35 patients (31 male, 4 female, mean age: 59.0 years±20.1) were screened and included in the study. The data were obtained through a clinical examination, a Quick-DASH score and a self-designed questionnaire. Clinical outcomes were assessed by evaluating the range of motion (ROM) of the reconstructed finger and the donor finger compared with the contralateral uninjured hand. In addition to ROM, a static two-point separation test was performed to assess the sensory function of the reconstructed finger. The follow-up period was between 1 year and 19 years (mean: 12.6 years±6.1).

Results: There was no significant difference in terms of ROM between the reconstructed finger and the donor finger compared with the contralateral uninjured hand. All patients reported normal discrimination between sharp and blunt objects. However, there was a significant difference in two-point discrimination between the reconstructed finger and the healthy contralateral finger (p<0.05). The average Quick-DASH score was 5.1 points. Satisfaction with the functional outcome in terms of mobility and load-bearing capacity of the cross-finger flap averaged 8.1 out of 10 points. Satisfaction with the aesthetic outcome of the reconstructed finger averaged 7.7 out of 10 points. In 4 cases, persistent pain was reported when the reconstructed finger was under stress. No cases of pain at rest were reported.

Conclusion: In the long run, cross-finger flaps are a safe and effective reconstructive procedure for covering defects in palmar injuries of the finger and fingertip amputation. They represent a simple, reliable, long-lasting reconstructive technique. The necessary temporary iatrogenic syndactyly does not lead to long-term limitations in the range of motion.

Autologous postmastectomy breast reconstruction is associated with favourable long-term clinical outcomes and superior patient-reported outcomes (PROMs) compared with implant-based reconstruction. However, adjuvant radiotherapy has traditionally been considered a relative contraindication to immediate flap-based reconstruction due to its unpredictable effects on the reconstructive outcome. While modern adjuvant postmastectomy radiotherapy (PMRT) has been able to significantly reduce acute and chronic radiation-induced complications, plastic surgeons still hesitate to offer immediate autologous reconstruction to patients expected to undergo adjuvant radiotherapy. More recently, evidence has emerged suggesting a paradigm shift in favour of immediate autologous reconstruction despite subsequent radiotherapy. At the 44^th Annual Meeting of the German-speaking Society for Reconstructive Microsurgery (GSRM) in Bern, Switzerland, a workshop discussed the literature on PMRT and autologous breast reconstruction, aiming to establish consensus among the participants. Several areas of agreement were identified, including the goals of postmastectomy reconstruction, specifically the creation of a soft and sensitive breast symmetrical in shape and size to the unaffected breast via the safest procedure possible. The importance of preserving the maximum amount of native breast skin envelope through skin- and nipple-sparing approaches was emphasised. Finally, a consensus was reached that PMRT should no longer be considered a contraindication to immediate autologous breast reconstruction.

Background: Surgical procedures of the hand are increasingly performed in an ambulatory setting. Postoperative analgesia is based empirically on the painfulness of individual surgical procedures without these having been examined systematically.

Patients and methods: The painfulness (visual analogue scale) of 722 surgical procedures of the hand and wrist (1 July 2021 to 30 June 2023) was assessed until day 5. Analgesia was conducted empirically in accordance with WHO principles. The primary endpoint was the pain sensation on the first postoperative day in bone and joint procedures compared with soft tissue or endoscopic procedures as well as hardware removals. Secondary endpoints were pain sensation in correlation with gender, age, duration of the procedure and preoperative analgesia.

Results: Bone and joint procedures were associated with significantly (p<0.001) more pain (5.42±2.8) compared with other procedures (3.47±2.6). Female (p=0.001) and younger patients (R>0.2) as well as longer procedure duration (R>0.2) showed a weak association with higher postoperative pain, whereas preoperative consumption of opioids was moderately associated with higher opioid intake (R=0.34). Overall, pain decreased continuously from the evening of the procedure (4.4±2.8) until day 5 (3.7±2.7; 2.8±2.4; 2.1±2.1; 1.6±1.9; 1.3±1.7) CONCLUSION: This data provides a scientific basis for pain medication supply following surgical procedures of the hand and wrist in an ambulatory setting. A broad range of pain perception must be considered, even in seemingly minor surgical procedures.

Background: Fractures of the distal radius have been traditionally classified based on the suspected mechanism of injury. Among clinicians, the terms "Colles" and "Smith" fractures are commonly used to refer to a distal radius fracture that is either displaced to the dorsal (Colles) or palmar (Smith) side of the radius. When analysing x-rays, it is not uncommon for a Smith fracture to be detected in cases where patients describe a fall on the wrist in an extended position. Thus, the question arises how a flexion-type fracture can occur after an extension injury. So far, only little research has been conducted into this subject.

Material and methods: The aim of this study was to analyse the mechanisms of injury that lead to various types of distal radius fractures. Particular emphasis was placed on "Smith" fractures and on the biomechanical, physiological and anatomical characteristics that contribute to their occurrence. To assess these relationships, data of fractures were collected following a life-like fracture simulation using a "drop-bench" in non-formalin fixated human specimens. These fractures were produced between January 2016 and December 2021. Biographic data of all specimens used were available. Additionally, all biomechanical and physical characteristics of the fracture simulation were fully documented.

Results: Of the 122 specimens with a full data set, 17 (13.9%) fractures were determined to be Smith fractures based on their radiological appearance. In 10 of these flexion fractures, the wrist was set in dorsal extension. The mean angle of extension was 86.3 degrees for flexion fractures compared to 90.5 degrees for extension fractures. Six out of 10 Smith-type fractures that were set in dorsal extension were also exposed to pronation, whereas only one was exposed to supination. The mean potential energy for fracture creation was 168.0 joules for Smith fractures in dorsal extension, whereas all other fractures showed a mean of 185.2 joules.

Conclusions: It can be concluded that a Smith fracture is not limited to being the result of a fall on the wrist in a flexed position. The same fracture may also be the result of a fall with the wrist in an extended position if certain physical factors are applicable.

We present the case of a 24-year-old man who sustained a scaphoid fracture in the presence of congenital scaphotrapezial and lunotriquetral coalitions. As the fracture progressed to a nonunion, a screw osteosynthesis was performed. The altered biomechanics caused by the two coalitions necessitated a dorso-proximal surgical approach, and two screws were implanted to prevent rotational instability. The scaphoid fracture healed entirely.
