Article Synopsis
  • The study compared recurrence rates of paresthesias in patients who had primary cubital tunnel surgery with and without wrapping the ulnar nerve in human amniotic membrane (HAM).
  • A total of 78 patients were analyzed, revealing that none of the 21 patients wrapped in HAM experienced recurrence of symptoms, while 19.3% of the 57 control patients did.
  • The results suggest that using HAM significantly lowers the risk of recurring symptoms, prompting the need for more extensive studies to explore its effectiveness in cubital tunnel surgery.

The differential diagnosis of abdominal pain is wide as both benign and malignant pathologies must be considered. There are currently no published case reports of low-grade appendiceal mucinous neoplasms (LAMNs) mimicking perforated diverticulitis. LAMNs are a heterogenous group of tumours, with no consensus treatment algorithm based on stage and histology.

Hiatus hernia is defined as a -diaphragmatic protrusion of the intra-abdominal contents through the oesophageal hiatus into the mediastinum. Surgical repair is indicated in symptomatic patients, with some patients presenting emergently with strangulation and ischaemia of hernial contents. In this situation, emergent decompression and surgical repair is indicated.

Adhesive small bowel obstruction (ASBO) is commonly caused by intra-abdominal adhesions, usually from prior surgery. Conservative management is the mainstay of treatment, with adhesiolysis required for non-resolving obstruction. An unusual patient presentation of ASBO is presented here, where the cause is proposed as an automatic implantable cardioverter defibrillator (AICD) within the abdomen.

Article Synopsis
  • Three patients underwent ulnar nerve transposition and were treated with human amniotic membrane (HAM) wrapping to aid recovery.* -
  • All patients later required reoperation for their original issues, not related to the ulnar nerve, which allowed for study of the transposed nerve.* -
  • The procedure showed reduced scar formation and easy separation of the nerve from surrounding tissue, indicating that HAM wrapping is beneficial in preventing complications.*

Purpose: In patient-specifically instrumented (PSI) total knee arthroplasty, the correlation between the pre-operative surgical plan, accuracy of the cutting block, and intra-operative resection size is unclear. The aim of this study was to evaluate the ability to accurately execute the PSI surgical plan and to add to the merging information with respect to this technology with the hypothesis that the PSI blocks would demonstrate good accuracy with regard to the bony thickness of the resections.

Methods: One hundred and thirty TKAs using PSI (MRI/long-leg radiographs) were retrospectively analysed.

Nerve and tendon lacerations of the foot and ankle region are relatively common. Acute nerve and tendon injuries should be repaired with appropriate techniques at the time of initial wound exploration. Primary nerve repair may help minimize the risk of painful neuroma formation; primary tendon repair can lead to better functional results than delayed repair.
