Dupuytren's disease is a progressive fibrotic condition of the hand. The underlying pathomechanism is not fully known. Dupuytren's contracture can be seen in patients with diabetes mellitus, chronic alcoholism, smoking, or hand trauma. It is uncommon to affect the neurovascular supply causing clinical symptoms. We describe a patient with idiopathic Dupuytren's disease complicated with bilateral ulnar neuropathies and highlight the importance of such rare treatable complication.

An elbow dislocation in a child with missed medial epicondyle fracture and late ulnar nerve palsy

Haflah NH, Ibrahim S, Sapuan J, Abdullah S

J Pediatr Orthop B, 2010 Sep;19(5):459-61.

PMID: 20555271 DOI: 10.1097/BPB.0b013e32833b6032

Elbow dislocations associated with a medial epicondyle fracture and ulnar nerve palsy are uncommon injuries. We present the case of an 11-year-old girl with an elbow dislocation treated by closed manual reduction. The medial epicondyle fracture was missed initially until she developed an ulnar nerve palsy 2 months later. Intraoperatively we discovered the bony epicondyle piercing the joint capsule and compressing the ulnar nerve. Removal of the bony fragment relieved her symptoms and she returned to normal activities at 1 year follow-up. We would like to highlight this rare occurrence and present the detailed history and management of this case.

Fulltext Cubitus Valgus with Tardy Ulnar Nerve Palsy - Functional Outcome of Milch Osteotomy without Anterior Transposition of Ulnar Nerve

PMID: 32983386 DOI: 10.5704/MOJ.2007.021

Introduction: To assess the results of Milch osteotomy in terms of deformity correction and functional outcome in the absence of ulnar nerve transposition.

Material and Methods: Nine patients with cubitus valgus deformity greater than 20° with tardy ulnar nerve palsy (TUNP) operated between 2012 and 2017 were evaluated. Correction by Milch osteotomy and fixation was done in each case, without osteosynthesis of the non-union lateral condyle humerus or transposition of the ulnar nerve. At one year post-operatively, carrying angle, elbow function (Mayo Elbow Performance Score) and ulnar nerve symptoms were assessed.

Results: The mean carrying angle pre-operatively was 30.8° on the affected side which improved to a mean of 8.3° postoperatively with an average correction of 22.5°. The mean elbow flexion pre-operatively was 129.4° which improved to 133.3° post-operatively. The mean preoperative MEP score was 76.7 which improved to a mean of 92.2 post-operatively (p < 0.01). TUNP recovered completely in all the patients.

Conclusion: Milch osteotomy is an effective procedure for cubitus valgus deformity correction and its associated tardy ulnar nerve palsy without a decrease in elbow ROM. Correction of even severe valgus deformities without concurrent anterior transposition of the ulnar nerve is likely to improve ulnar nerve symptoms.

AIM: This study was conducted to measure the cross sectional area (CSA) of the ulnar nerve (UN) in the cubital tunnel and to evaluate the role of high-resolution ultrasonography in the diagnosis of ulnar nerve neuropathy (UNN).

MATERIALS AND METHODS: This was a cross sectional study with 64 arms from 32 patients (34 neuropathic, 30 nonneuropathic). Diagnosis was confirmed by nerve conduction study and electromyography. The ulnar nerves were evaluated with 15MHz small footprint linear array transducer. The ulnar nerve CSA was measured at three levels with arm extended: at medial epicondyle (ME), 5cm proximal and 5cm distal to ME. Results from the neuropathic and nonneuropathic arms were compared. Independent T-tests and Pearson correlation tests were used. P value of less than 0.05 was considered significant.

RESULTS: Mean CSA values for the UN at levels 5cm proximal to ME, ME and 5cm distal to ME were 0.055, 0.109, 0.045 cm(2) respectively in the neuropathic group and 0.049, 0.075, 0.042 cm2 respectively in the non-neuropathic group. The CSA of the UN at the ME level was significantly larger in the neuropathic group, with p value of 0.005. However, there was no statistical difference between the groups at 5cm proximal and distal to the ME, with p values of 0.10 and 0.35 respectively.

CONCLUSION: There is significant difference in CSA values of the UN at ME between the neuropathic and non-neuropathic groups with mean CSA value above the predetermined 0.10cm(2) cut-off point. High-resolution ultrasonography is therefore useful to diagnose and follow up cases of elbow UNN.

Fulltext Cubitus Valgus with Tardy Ulnar Nerve Palsy - Is Anterior Transposition of the Ulnar Nerve Always Necessary? A Case Report

Anuar-Ramdhan IM, Remli R, Abdul-Rashid AH, Ibrahim S

Malays Orthop J, 2020 Jul;14(2):126-129.

PMID: 32983387 DOI: 10.5704/MOJ.2007.010

Tardy ulnar nerve palsy is a known complication of cubitus valgus. The options for treating the ulnar neuropathy include anterior nerve transposition or neurolysis. We report on an 11-year-old boy who had a tardy ulnar nerve palsy due to cubitus valgus resulting from a non-union of a lateral condyle fracture of the humerus. Anterior transposition of the ulnar nerve was not done after the closing wedge osteotomy of the distal humerus. The close wedge osteotomy relieved the tension on the nerve and not transposing the ulnar nerve anteriorly prevented an iatrogenic nerve injury. The patient had no restriction with activities of daily living at the six years follow-up although neurological recovery was incomplete.

Fulltext Olecranon Osteotomy Approach for Complex AO-13C Fractures of Distal Humerus: A Prospective Analysis of 24 Cases

Singh R, Singh H, Kanodia N

Malays Orthop J, 2019 Mar;13(1):30-35.

PMID: 31001381 DOI: 10.5704/MOJ.1903.005

Introduction: Olecranon osteotomy is well described approach for complex intra-articular distal humeral fractures. In this study, we investigated the usefulness and complications of olecranon osteotomy approach for such fractures. We hypothesise that outcome is comparable in young adults and middle age group and also functional outcome is independent of fracture subtype following surgical fixation. Materials and Methods: Between December 2012 and September 2015, twenty-four adult patients (male: 15, female: 9) having mean age of 41.4 years with closed intra-articular fracture (AO-13C) were surgically managed using olecranon osteotomy approach and were followed-up for a mean of 28.5 months (range: 22-35 months). Functional outcome was measured using Mayo Elbow Performance Score (MEPS) and complications were observed. Statistical analysis was done using Student t-test and Kruskal Wallis test. Results: All fractures united by the end of three months. Mean elbow flexion achieved was 123°, mean extension lag was 9° and mean active arc of motion was 114°. Mean MEPS was 87 (excellent: 8, good: 14, fair: 1 and poor: 1). Post-operative transient ulnar nerve palsy was noted in two cases, heterotopic ossification (HO) was in one case, infection in two cases, implant prominence in five and elbow stiffness in three cases. Motion arc was higher in young adults and MEPS was comparable in both age group. Functional outcome was also dependent on fracture subtype. Conclusion: The olecranon osteotomy approach for distal humerus fractures had good functional outcome with fewer complications. Joint congruity and fixation could easily be assessed intraoperatively.
